NAME

    Netdisco INSTALL -- Instructions for setting up the Netdisco
    application.

VERSION

    Netdisco 1.0

AUTHOR

    Developed by team of Open Source authors headed by Eric Miller, Bill
    Fenner, and Oliver Gorwits, originally created by Max Baker. See list at
    the end of README of all the contributors.

    Netdisco was created at the University of California, Santa Cruz (UCSC),
    Networking and Technology Services (NTS) department. UCSC continues to
    support the development of Netdisco by providing development servers and
    beer.

    The Netdisco project is hosted by Source Forge at
    <https://sourceforge.net/projects/netdisco> and
    <https://sourceforge.net/projects/snmp-info>.

SUPPORT

    Netdisco is an Open Source project created and maintained by volunteer
    developers.

    Please use the "netdisco-users" mailing list for all help, problems and
    comments. Developers, patches, and ideas are always welcome.

    In Case of Problems
        In case of problems, the first thing you should do is search for
        answers on the mailing list at
        <http://sourceforge.net/search/?group_id=80033&type_of_search=mlists
        >.

    To ask a Question
        To subscribe to the "netdisco-users" mailing list to ask questions
        go to <http://lists.sourceforge.net/lists/listinfo/netdisco-users>.

    To report a bug
        To report bugs, please use the Bug tracker on the Netdisco Source
        Forge project page at
        <https://sourceforge.net/tracker2/?group_id=80033&atid=558508>

    To become a developer
        If you would like to help develop Netdisco, or have code to
        contribute, please submit your code to the patches tracker at
        <https://sourceforge.net/tracker2/?group_id=80033&atid=558510> and
        join us on the "netdisco-devel" mailing list.

    To register your install of Netdisco
        The developers are now maintaining a registry of Netdisco installs.
        This is mainly for morale boosting purposes, but also helps us
        direct feature requests to our target audience. One drawback of the
        Source Forge system is that we have no idea how many people are
        using the software compared to the number of downloads. So after you
        have Netdisco up and running please spend a minute to let us know
        you're using it at <http://netdisco.org/register.html>.

INSTALL FLAVORS

    There are three general flavors of installs out there for Netdisco:

    From Source
        The most common way is to install it from source on your machine
        using an install script (see bin/install and
        http://www.auburn.edu/~gouldwp/netdisco/), or manually using this
        document.

    From Package
        Netdisco is available as a package / port on a few flavors of Linux
        and BSD. Check your favorite package repository first before going
        to the trouble of installing it manually.

    Virtual Machine / VMWARE Applicance
        Charles Goldsmith maintains a VMWARE Appliance version of Netdisco
        at <http://wokka.org/netdisco/>. This is by far the easiest way to
        get up and running w/ Netdisco.

REQUIREMENTS

    Netdisco is built using lots of fine Open-Source tools:

    *   Perl

        5.8.x and newer advised. Whatever version that comes with your
        distro should be fine.

    *   Perl Modules

        Listed below

    *   Net-SNMP

        5.1.x and newer advised. Reported working on 5.0.x as well.

    *   Postgres SQL Server

        Version 8.x or higher suggested.

        Reported working for versions 7.2, 7.3, 7.4, 8.0, 8.1

    *   Mason

        1.26 or newer required. 1.39 or newer advised, especially for
        Apache2 installs.

    *   Apache

        1.3.x and 2.x supported. 2.x strongly preferred.

    *   mod_perl

        Get the mod_perl version to match your Apache:

        Apache 1.3.x
            mod_perl version 1.29 or higher is recommended.

        Apache 2.x
            Do not install version 1.99! Make sure you have mod_perl version
            2.02 or later.

    *   GraphViz (Optional)

        Version 2.22 or higher recommended.

    See INSTALL below for details on how to retrieve and install each
    prerequisite.

  OS

    Netdisco was developed on a FreeBSD system but should work on any system
    that Postgres, Perl, Apache, and Net-SNMP run on.

    Linux is a sure bet. Successful installs have been reported under
    Redhat, Mandrivia, Gentoo and Debian. A beta RPM is available for
    Mandrivia, but may be out of date. One user has reported getting
    Netdisco running on OS X. Solaris has been successful for 8 and 10.
    Windows will take a lot of massaging but should be possible under
    Cygwin.

    See "OS Specific Notes" below for details.

UPGRADE

    If you are upgrading your copy of Netdisco, please read through this
    file and then read the "UPGRADE" document in this directory.

INSTALL

    This is not a terribly easy install. If you aren't comfortable
    installing programs from source and using a text editor, get some help.
    Some packaged versions of Netdisco are available.

  1. Download Netdisco

    Get the newest version from <http://www.netdisco.org>.

    [1.1] Unarchive Netdisco
            tar xvfz netdisco-x.xx_with_mibs.tar.gz

    [1.2] Create a directory for Netdisco and move the files into that dir
            mkdir /usr/local/netdisco
            mv netdisco-x.xx/* /usr/local/netdisco

    [1.3] Non-Standard install Directory
        If you plan to install to a directory other than
        "/usr/local/netdisco" then you must change a couple files. Otherwise
        Skip down to Number 2.

        [1.3.1] Shell Scripts
            The following shell scripts require you specify the Netdisco
            directory if it is not in the default location:

                sql/pg -d /path/to/netdisco
                bin/netdisco_daemon

        [1.3.2] netdisco.conf
            Set the "home" option in netdisco.conf.

        [1.3.3] netdisco_apache.conf
            Change all the appearances of "/usr/local/netdisco" in
            netdisco_apache.conf to match your new directory.

        [1.3.4] netdisco_apache_dir.conf
            Change all the appearances of "/usr/local/netdisco" in
            netdisco_apache_dir.conf to match your new directory.

  2. Create a Unix User/Group for Netdisco

    [2.1] Create a user and group named "netdisco"
        Linux:

            useradd -d /usr/local/netdisco netdisco

        BSD:

            adduser netdisco

    [2.2] User Permissions
        Give this user permission to the installed files

            chown -R netdisco.netdisco /usr/local/netdisco

  3. Add Unix Administrators to Netdisco Group

    Once Netdisco is up and running most administration can be done from the
    Web interface. Whoever will be doing the back-end administration will
    need to have write access and will need write access on Netdisco's
    files.

    Add the unix account names of administrators that will modify the source
    code or use the command line interface interface to the "netdisco" group
    in /etc/group.

    Don't forget to logout and login after adding yourself to a group.

  4. Postgres

    Netdisco runs Postgres SQL as its database back-end.

    [4.1] Install Postgres
        See the section "OS Specific Notes" below for any notes relating to
        your operating system of for a binary version.

        There is probably a binary package all ready for you. See your
        distribution's instructions for more help.

        If you cannot use a binary package, download and compile the source
        code from <http://www.postgresql.org>.

        If you are installing Postgres from source you may have to run these
        two commands in order to install the DBD::Pg Perl module later on :

            export POSTGRES_INCLUDE=/usr/local/postgres/include
            export POSTGRES_LIB=/usr/local/postgres/lib

        You may also have to modify your /etc/ld.so.conf to include your new
        POSTGRES_LIB directory. Don't forget to run "ldconf" afterwards.

    [4.2] Configure Postgres
        Netdisco's settings in Postgres are

         Database User     : netdisco
         Database Name     : netdisco
         Database Password : you choose it

        Edit netdisco.conf and netdisco_apache.conf to match this user name
        and password.

        Follow these steps to setup Netdisco in Postgres.

    [4.3] Permissions
        If you have just setup Postgres for the first time you may have to
        change the default permissions in $PG_DATA/pg_hba.conf. $PG_DATA
        might be in /usr/local/pgsql or in /var/db, depends on your OS.
        Check the postgres users' homedir files for the location of
        $PG_DATA.

        For installation you must give the database user access to the
        "template1" database. The following line will give all users who
        have logon permissions in Unix access to the "template1" database.

            local template1 all ident

        Restart Postgres. If you have permission problems try the following
        line which opens up access to all users.

            local template1 all all

        Next you must give the "netdisco" database user access to the
        "netdisco" database. The following line will give all database users
        access to a database that is the same name as them. This line must
        be put above all the rest of the uncommented lines in the
        pg_hba.conf file to take precedence.

            local sameuser all md5

        For older 7.3 or 7.4 installs of Postgres you may have to swap "md5"
        for "crypt". Upgrade. Please.

        Finally if you would like to have "root" be able to access all
        databases, try this one :

            local all root trust

    [4.4] Restart Postgres
        You must now restart Postgres

        Linux : one of these three

            /etc/rc.d/init.d/postgresql restart
            service postgresql restart
            /etc/rc.d/postgresql restart

        FreeBSD :

            /usr/local/etc/rc.d/*pgsql* restart

        If there are problems with this step you will receive an error that
        mentions something about pg_hba.conf.

    [4.5] Create Database.
        Make sure Postgres is up and running.

        The "pg" command use netdisco.conf to find the database user name
        and password. Make sure that the database user name and password are
        set.

        As root, run "sql/pg --init" to create the database and user for
        Netdisco.

        When you are prompted for a password, enter the new password for the
        database user you are creating. This is the same password you set in
        netdisco_apache.conf and in netdisco.conf. The "pg" command has
        additional options shown in "pg --help"

            cd /usr/local/netdisco/sql
            ./pg --help
            ./pg --init

        If you get permissions errors, find out the name of your database
        user. This is the "unix" user that the Postgres database is running
        as. The default name for some Linux RPM versions is "postgres" and
        for some BSD installations "pgsql". If yours is different, please
        specify it with the "-u" option to sql/pg.

    [4.6] Check Settings
        Now as a non-privileged user (root) make sure you can get into the
        database by running "sql/pg". The database user password given above
        will be retrieved from netdisco.conf.

            cd /usr/local/netdisco/sql
            ./pg

        You should see output similar to the below:

            Welcome to psql 8.0.6, the PostgreSQL interactive terminal.

            Type:  \copyright for distribution terms
                   \h for help with SQL commands
                   \? for help with psql commands
                   \g or terminate with semicolon to execute query
                   \q to quit

            netdisco=>
            netdisco=> \q

    [4.7] Optimizations
        If you have freshly installed Postgres then the default memory usage
        NEEDS to be increased for efficiency. See the Postgres documentation
        for postgresql.conf. Newer versions may have options to turn on for
        automatic tuning.

        Specifically, you really need to up the maximum connections and
        shared memory settings. After you have Netdisco running on a large
        installation it would be of great benefit to get a Postgres guru in
        there to tune things for you. See README for more info about how to
        speed things up now and again.

        See
        <http://www.postgresql.org/docs/current/static/kernel-resources.html
        > for kernel settings related to Postgres that you *should* check.

    [4.8] Postgres Startup
        Make sure that Postgres is set to start on reboot of the server.

        Linux
                chkconfig postgresql on

        BSD Make sure that the file in "/usr/local/etc/rc.d" is alright and
            you have added

                postgresql_enable="YES"

            to /etc/rc.conf.

    [4.9] Postgres Maintenance
        Read the section in README about Database Maintenance... every once
        in a while you may have to run a "VACUUM" and "REINDEX" by hand if
        things get too slow. This appears to be less necessary in Postgres
        8.0 and up.

    [4.10] Remote Database (Optional)
        If you have Postgres installed in a remote location then all you
        have to do is add that host information to the "db_Pg" line in
        netdisco.conf.

            db_Pg = dbi:Pg:dbname=netdisco;host=HOSTNAME;port=PORT;

        On the Postgres machine, allow your remote front end to contact the
        back-end database. Here is a sample line in pg_hba.conf.

         #TYPE  DATABASE          USER            IP-ADDRESS              IP-MASK           METHOD
         host   netdisco        netdisco         101.102.103.104         255.255.255.0       md5

        Don't forget to restart Postgres after changing the pg_hba.conf
        file.

  5. SNMP

    There are three components to set up for SNMP:

   5.1.  Net-SNMP

    Net-SNMP lives at <http://net-snmp.sourceforge.net>.

    There are two known bad versions: 5.2.3 and 5.3.1 !

    Please use the older working versions 5.2.2 or 5.3.0.1, or try the newer
    5.2.4, 5.3.2 or 5.4 when they're available. See
    <http://www.net-snmp.org/dev/schedule.html> for release schedule plans.
    You can also use a nightly version from the appropriate patch branch,
    from <http://www.net-snmp.org/nightly/tarballs/>.

    The symptom of the failure is getting an error "Not an ARRAY reference
    at SNMP/Info.pm line xxx".

    A workaround if you must use a buggy Net-SNMP version is to use SNMPv1
    or turn off bulkwalk with "bulkwalk_off: yes" -- but the best thing to
    do is change your Net-SNMP version.

    You can update the perl SNMP module seperately from the libraries and
    binaries, using CPAN. As of this writing, the current module on CPAN is
    5.0301002 which does not have this bug. Only try to use this module with
    a matching Net-SNMP version - i.e., if you get a warning like this when
    you try to install:

            ERROR:
            Net-SNMP installed version: 5.2.3 => 5.0203
            Perl Module Version:        5.0301

    then please try a different method.

    [5.1.0] Binary Install
        Check the Net-SNMP page for binaries and see "OS Specific Notes"
        below for details.

    [5.1.1] Source Install
        Download Net-SNMP from http://net-snmp.sourceforge.net

        This used to be called ucd-snmp. However, don't download ucd-snmp;
        it is too old.

    [5.1.2] Install Net-SNMP to include Perl module that comes inside the
    distribution.
        When you run "./configure", make sure you add the switch
        "--with-perl-modules"

            ./configure --with-perl-modules --enable-shared
            make
            make install

        If you already have Net-SNMP installed, then go to the source
        directory and in the "perl" subdirectory and run "perl Makefile.PL"

            cd /path/to/net-snmp-5.1.x/perl
            perl Makefile.PL
            make
            make install


         ********************************************************************

        DO NOT INSTALL the "SNMP::" or "Net::SNMP" modules off of CPAN.
        These modules are not related to Net-SNMP and are not compatible
        with Netdisco.

         ********************************************************************

    [5.1.3] Configure Net-SNMP for a non-standard setup (Optional)
        You probably will not have to do this step unless you have installed
        Net-SNMP somewhere other than /usr/local/ or have some specific SNMP
        defaults to change for these tools. Usually the settings in
        netdisco.conf are more than enough.

            snmpconf

        Make sure to set the MIB dir if non-standard or you are not using
        the MIBS that come with Netdisco.

         (Textual mib Parsing -> Specifies directories to be searched for mibs)

        Make sure this newly created snmp.conf lives in
        /usr/local/share/snmp or wherever you put a custom install.

   5.2. SNMP::Info

    SNMP::Info is one half of the Netdisco application.

    SNMP::Info holds all the device-specific code to retrieve data from
    network devices via SNMP. A wide variety of devices are supported. You
    may need to add support for other devices if they do not follow a
    standard interface. This is not too complex. See SNMP::Info and consult
    the mailing list archives for more details.

    SNMP::Info is available from <http://snmp-info.sourceforge.net> and from
    CPAN. You must have Net-SNMP installed before installing it.

    You have four different options in installing SNMP::Info

    [5.2.1] CPAN
            perl -MCPAN -e shell
                o conf prerequisites_policy ask
                install SNMP::Info

    [5.2.2] From Source
        Download newest version from <http://snmp-info.sourceforge.net>

            tar xvfz SNMP-Info-1.x.tar.gz
            cd SNMP-Info-1.x
            perl Makefile.PL
            make install

    [5.2.3] From CVS
        If you plan to add or change device support in SNMP::Info to
        customize Netdisco to your devices, you should install SNMP::Info
        this way.

            make snmp

        This will create the SNMP/ directory where SNMP::Info will live.
        Periodically you should re-run

            make snmp

        To update to the most current CVS version.

    [5.2.4] From Package
        See "OS Specific Notes" below for details.

   5.3.  MIBs

    MIBs that are required for SNMP::Info are included with Netdisco in the
    mibs/ directory if you installed the "netdisco-1.0_with_mibs" package.

    If you installed the "netdisco" package without included MIB files, then
    please download the "netdisco-mibs" package from
    <http://sourceforge.net/project/showfiles.php?group_id=80033>. Place
    these files in "/usr/local/netdisco/mibs".

  6. GraphViz  (Optional)

    GraphViz is used to create the Network Map.

    It lives at <http://www.graphviz.org/>.

    [6.1] Download
        Get the newest version from <http://www.graphviz.org/pub/graphviz>.
        Unarchive and install. Some binary versions are available.

    [6.2] True Type Font
        Copy a True Type Font file (.ttf) into the Netdisco directory and
        change "node_font" in netdisco.conf to match.

            cp /path/to/windows/fonts/lucon.ttf /usr/local/netdisco

        You can grab arial.ttf or lucon.ttf out of the c:\windows\fonts
        directory of any Windows machine.

    [6.3] Graph Settings
        Review other graph settings in netdisco.conf. See README for details
        on the settings.

    [6.4] Check Path
        Make sure that "neato" or "twopi" is in your path, and in the path
        in netdisco.crontab.

            which twopi
            which neato

        After the Perl Modules step below, make sure the Graphviz Perl
        module got installed

            perldoc GraphViz

        NOTE: You can safely ignore all warnings about "size too small for
        label".

  7. Setup Apache

    [7.1] Apache2
        Using recent versions of Mason and mod_perl, Netdisco runs fine
        under Apache2.

    [7.2] Apache1
        It is strongly advised to use Apache2. Consider section 7.2 as
        historical.

        See the O/S specific notes at the bottom of this document for a
        binary install or install Apache 1.3.x From Scratch:

        Comment out the lines at the top of netdisco_apache.conf that are
        related to Apache2.

        Install Apache 1.3.x and mod_perl 1.x and mod_ssl

        Netdisco is designed to work in a secure (https) or non-secure
        environment. Due to the security and privacy concerned associated
        with this data, using a secure server is recommended.

        Below is my method if you haven't installed apache and mod_perl
        before. I statically compile mod_perl, and mod_ssl then leave the
        rest of the modules as dynamically loadable objects (DSO).

        [7.2.1] Download and Unarchive
            Get Apache from <http://httpd.apache.org>

            Get mod_perl from <http://perl.apache.org>

            Get mod_ssl from <http://www.modssl.org>

            Unarchive all three to the same directory, maybe /usr/local/src

        [7.2.2] Inital Apache Setup
            This step makes the framework that mod_ssl and mod_perl need.

             cd apache_1.3*
             ./configure

            No need to make it yet.

        [7.2.3] mod_ssl
            Mod_SSL gives us a secure server (https) for Netdisco to run
            under.

            The OpenSSL library is a prerequirement for mod_ssl and may or
            may not already be on your system. See "OS Specific Notes" at
            the bottom of this document.

            To use a source version, you need to point the apache1 installer
            to the install. First follow the instructions in the INSTALL
            that comes with "mod_ssl". Then use the command below:

             SSL_BASE=/path/to/openssl-0.9.x \
             ./configure \
                --with-apache=../apache_1.3.x \
                --disable_rule=SSL_COMPAT

        [7.2.4] mod_perl
            This step sets up mod_perl for this copy of apache :

             cd ../mod_perl-1.x
             /usr/local/bin/perl Makefile.PL \
                    APACHE_SRC=../apache_1.3.x/src \
                    EVERYTHING=1 \
                    DO_HTTPD=1 \
                    USE_APACI=1 \
                    PREP_HTTPD=1 \
                    PERL_SECTIONS=1

             make

        [7.2.5] Apache Again
            Now we're ready to make the main apache and install all of the
            above (mod_ssl, mod_perl, and Apache).

             cd ../apache_1.3*
             ./configure \
                    --prefix=/usr/local/apache \
                    --enable-module=most \
                    --enable-shared=max \
                    --activate-module=src/modules/perl/libperl.a \
                    --with-perl=/usr/local/bin/perl \
                    --enable-module=ssl
             make
             make certificate
             make install

        [7.2.6] Install mod_perl
             cd ../mod_perl*
             make install

    [7.3] Apache Configuration Files
        Add the following lines in your "httpd.conf".

        Your "httpd.conf" will live in "/usr/local/apache/conf" if you
        installed using the method above. For system installed packages, try
        "/etc/httpd" or "/usr/local/etc/httpd".

        [7.3.1] In the Global Section
            Add this line once in the end of "httpd.conf" not in a
            VirtualHost section.

                Include /usr/local/netdisco/netdisco_apache.conf

        [7.3.2] No virtualhosts
            If you do not have virtual hosts setup and/or you have a main
            server, add this line right after the first include :

                Include /usr/local/netdisco/netdisco_apache_dir.conf

        [7.3.3] In each VirtualHost
            If you have Virtual Hosts or are setting up a secure server, put
            the following line in each of them that you want Netdisco turned
            on for:

            If you are not using Virtual Hosts, then add this line under the
            *netdisco_apache.conf* line.

                Include /usr/local/netdisco/netdisco_apache_dir.conf

            Make sure you have this include line for the secure server
            virtual host *:443 at the bottom of http.conf.

    [7.4] Mason Data Directory
        Set the Mason data directory writable to the apache user that does
        the requests.

        Assuming "nobody" is the user that the apache web server runs under,
        run this command as "root" :

            mkdir /usr/local/netdisco/mason
            chown nobody.netdisco /usr/local/netdisco/mason

        The name of the user is listed in "httpd.conf" under the "User"
        directive. Some distros use the name "apache" or "www" as the web
        server unix user.

  8. Perl Modules

    Below is a list of required modules for Netdisco, freely available from
    CPAN <http://www.cpan.org>. Many of these modules have prerequisite
    modules. Many of these are available in distros already as packages.

    PLEASE check that you have these in package form first to allow for
    automatic updating of these dependency libraries. A good place to start
    is the Mason library.

    [8.1] Install required Perl modules from CPAN
        Use the CPAN module that comes with Perl to install the modules and
        their prerequisites automatically:

            perl -MCPAN -e shell

                o conf prerequisites_policy ask
                install Digest::MD5
                install Bundle::DBI
                install Apache::DBI
                install DBD::Pg
                install DB_File      (for Apache::Session)
                install Apache::Session
                install HTML::Entities
                install HTML::Mason
                install MasonX::Request::WithApacheSession
                install Graph        ( > 0.50 )
                install GraphViz     ( > 2.02 )
                install Compress::Zlib (probably already have this one)
                install Parallel::ForkManager
                install Net::NBName (optional for NetBIOS lookup on devices)
                install Net::LDAP (optional for LDAP authentication)
                install Net::SSLeay (optional for encrypted LDAP authentication)
                install IO::Socket::SSL (optional for encrypted LDAP authentication)

        For Apache1 install these modules:

                install Apache::Test (for Apache::Request, you may need to do a 'force install')
                install Apache::Request

        For Apache2 install this module:

                install Apache2::Request

        Some of these you will probably already have installed. Others you
        may need to force with "force install ModuleName". Do Not include
        the comments in (parens)!

    [8.2] Non-Standard Perl Location
        If you don't have Perl installed in "/usr/bin", you will need to
        modify the first lines of netdisco and bin/doc_munge to point to the
        version of Perl you would like to use.

  9. Netdisco Configuration

    [9.1] netdisco.conf
        Modify netdisco.conf to match your site.

        See README for detailed configuration descriptions.

    [9.2] netdisco_apache.conf
        Change the follow lines in netdisco_apache.conf to match your
        database user name and password that you picked in step 4.2:

            session_user_name
            session_password
            session_cookie_domain

    [9.3] netdisco.crontab
        Use this crontab to control the frequency of data collection done by
        Netdisco. See section 15 of this document for details.

        Change "center_network_device" to a network device that is well
        connected to the main segment by a supported discovery protocol
        (CDP/FDP/SONMP/LLDP).

    [9.4] Add a web user in Netdisco
        Add a user to the Netdisco application that will be the
        administrator account.

            /usr/local/netdisco/netdisco -u joebob

        Add more users from the web "Admin Panel" once Netdisco is up and
        running.

    [9.5] Make Documentation (CVS Versions Only)
        This step is only necessary if you have installed from CVS.

        i. Perl Location
            Make sure that the "POD2TEXT" lines in Makefile point to where
            your Perl binaries are installed.

        ii. Create Docs
            This step will create documentation files from the source
            ".pod", ".pm", and ".pl" files.

             cd /usr/local/netdisco && gmake doc

            Run this step if you would like the SNMP::Info documentation
            available from Netdisco.

    [9.6] Change Permissions on Config files
        Since the config files contain SNMP community strings and database
        passwords, you must make them only available to the administrators
        for security.

         chgrp netdisco /usr/local/netdisco/*.conf
         chmod 660 /usr/local/netdisco/*.conf

  10. OUI Database

    The "Organizationally Unique Identifier" (OUI) database allows Netdisco
    to identify the manufacture of a network card using the first 24 bits of
    the MAC address.

    Run the following command to import the contents of oui.txt into your
    database.

        cd /usr/local/netdisco
        netdisco -O

    If you run into errors because of UTF-8 or other exotic characters in
    oui.txt you may need to add this line to netdisco.conf.

        db_Pg_env = PGCLIENTENCODING => iso8859-1

    You may also try changing the above from "iso8859-1" to "UTF-8".

    [10.1] Updating oui.txt (Optional)
        The database of OUIs is needed by Netdisco and is available from the
        IEEE.

        This will use "wget" to download oui.txt from the IEEE and import it
        into the Netdisco database.

            cd /usr/local/netdisco
            gmake oui

        If you do not have "wget" download oui.txt manually and run
        "netdisco -O".

  11. Restart Apache

    Now that you have everything setup, "cold" restart the web-server.

        apachectl stop
        apachectl start

    Check the apache error_log for errors. See "OS Specific Notes" below for
    details.

  12. Discover a Device in Netdisco

    Pick a device that you can access with the command "snmpwalk". Tell
    Netdisco to discover that device:

        cd /usr/local/netdisco
        ./netdisco -d devicename

    Make sure that this step actually works. This is a good metric that you
    have now installed Netdisco correctly. Add the *-D* flag to get copious
    debugging info.

  13. Create Network Topology

    See README for a description of *Topology Information*.

    If your network uses a supported topology discovery protocol
    (CDP/FDP/SONMP/LLDP) pick a device that you consider close to the center
    of the network and start an auto-discovery from there:

        cd /usr/local/netdisco
        ./netdisco -r myrouter

    If your network is *not* CDP friendly, then see README for how to use
    the manual topology file netdisco-topology.txt.

    You MUST supply Netdisco with a working topology or MAC addresses will
    show up on uplink ports instead of end ports.

  14. Test Web Side

    First restart Apache so that Netdisco will see the changes that you have
    made in netdisco.conf. Note that a *graceful* restart will not re-read
    the configuration file. A full restart is required. See Step 11.

    Next, point a browser to */netdisco* on the server you have Netdisco
    installed on.

        http://localhost/netdisco

    If everything is working you should be able to login with the user name
    and password you added in Step 9.4. You should also be able to access
    the Admin Panel.

    If you have problems, check the error_log of apache for messages.

        tail /usr/local/apache/logs/error_log

  15. Add Cron Jobs

    Once you're sure Netdisco is setup correctly, modify netdisco.crontab.

     vi netdisco.crontab

    Network Discovery
        Change "center_network_device" to one of your core routers or
        switches.

    Data Collection
        You may want to fine-tune these jobs to your network. If jobs run
        too frequent and overlap, nothing bad will happen, it's just higher
        load on your network devices and Netdisco server.

        Once Netdisco has been running for a day, look at the "BackEnd Log"
        in the web browser and see how long each of the jobs is taking to
        finish. If there is overlap, for example if your arpnip is taking
        over 60 minutes or your macsuck is taking over 120 minutes, then
        consider decreasing the frequency of these jobs as to not cause
        extra load on your network devices.

    Now, as "root", load the crontab for the "netdisco" user.

        su
        crontab -u netdisco /usr/local/netdisco/netdisco.crontab

  16. Start the Netdisco Admin Daemon

    The admin deaemon performs administration jobs that are requested from
    the web front-end. See README for a full description of the admin
    daemon.

        /usr/local/netdisco/bin/netdisco_daemon start

    The daemon will be respawned daily in the Cron job listed above. The
    restart is not 100% necessary, it is added as a precaution in case any
    of the prerequisite libraries have memory leaks.

    [16.1] Make the Admin Daemon start at every boot
        If you would like the daemon to be started upon bootup, then do the
        following:

        Linux
            This is for Redhat/Mandrake/Fedora. Debian and Gentoo might be a
            little different.

                ln -s /usr/local/netdisco/bin/netdisco_daemon /etc/rc.d/init.d
                chkconfig --add netdisco_daemon
                chkconfig netdisco_daemon on

            Now you should be able to use this command:

                service netdisco_daemon {stop,start,restart,status}

        FreeBSD
                ln -s /usr/local/netdisco/bin/netdisco_daemon /usr/local/etc/rc.d/netdisco.sh

        Other
            Add the following line to your /etc/rc.d/rc.local file :

                /usr/local/netdisco/bin/netdisco_daemon start

OS Specific Notes

  FreeBSD

    A port is available for FreeBSD in "/usr/ports/net-mgmt/netdisco". Make
    sure that the port is up to date with this version of Netdisco. This is
    the best way to install Netdisco on FreeBSD.

    *   Postgres

        Install Postgres from ports:

            cd /usr/ports/databases/postgresql83-server
            make install

        Make sure Postgres is configured to start at system startup time by
        putting

            postgresql_enable="YES"

        in /etc/rc.conf.

        Next initialize the database:

            /usr/local/etc/rc.d/010.pgsql.sh initdb

        And start the database server:

            /usr/local/etc/rc.d/010.pgsql.sh start

    *   Net-SNMP

        Install Net-SNMP from ports.

            cd /usr/ports/net/net-snmp && make install

    *   Make

        Anywhere in this document you see a reference to make you should run
        gmake.

    *   SNMP::Info

        SNMP::Info is available on ports. Please check that the version
        listed there is as new as the version required by Netdisco.

            cd /usr/ports/net-mgmt/p5-SNMP-Info
            make install

    *   GraphViz

        GraphViz is available on ports:

            cd /usr/ports/graphics/graphviz && make install

    *   Apache Restart

        For the ports version of apache, to cold restart (ie. for Step 11)
        or for whenever you change the config file, use this command :

            /usr/local/etc/rc.d/apache2.sh stop
            /usr/local/etc/rc.d/apache2.sh start

        or

            /usr/local/etc/rc.d/apache.sh stop
            /usr/local/etc/rc.d/apache.sh start

        Also, double-check that Apache starts on its own at reboot. On BSD,
        make sure that you've added

            apache2_enable="YES"

        to /etc/rc.conf.

    *   Perl Modules

        You can install these Perl modules from Ports

            www/p5-HTML-Mason
            database/p5-DBI
            database/p5-DBD-Pg
            www/p5-Apache-DBI
            www/p5-Apache-Session
            www/p5-MasonX-Request-WithApacheSession

    *   Apache2

        Install these ports

            www/apache22
            www/mod_perl2
            www/p5-libapreq2

    *   Apache1

        If you choose to use apache1 from source you will need to install
        OpenSSL to provide a secure (https) server.

        Installing OpenSSL :

            cd /usr/ports/devel/mm && make install
            cd /usr/ports/security/openssl && make install

        Setup mod_ssl :

            cd /path/to/mod_ssl_1.x.x
            SSL_BASE=SYSTEM \
                ./configure \
                    --with-apache=../apache_1.3.x \
                    --disable_rule=SSL_COMPAT

  Mac OS X

    *   Postgres

        See <http://developer.apple.com/internet/macosx/postgres.html> for
        detailed instructions on installing PostgreSQL with OS X.

    *   GraphViz

        It is reported to be in "DarwinPorts" or you can check out
        <http://www.phil.uu.nl/~js/graphviz/>.

    *   Apache1

        See the very old, following three links in addition to this document
        to use Apache1 w/ OS X:

         http://www.oreillynet.com/pub/a/mac/2002/11/05/apache_osx.html
         http://www.oreillynet.com/pub/a/mac/2002/12/18/apache_modssl.html
         http://www.oreillynet.com/pub/a/mac/2003/02/07/libapreq_update.html

  Linux - Generic

    Here are some notes for installing Netdisco on Linux. If your distro is
    not listed here, look over the install scripts for other distros at
    <http://www.auburn.edu/~gouldwp/netdisco/> in the READMEs section.

    *   Net-SNMP

        If you have installed the Net-SNMP RPM from an "old" Redhat or
        Mandrake it does not include the Perl modules. Uninstall it and
        install a newer version by hand as below.

            rpm -e net-snmp

        Same goes for Debian. DO NOT use the apt-get version of Net-SNMP,
        install by hand (it's easy!).

    *   GraphViz

        For Redhat and Mandrake systems you will make sure that a lot of
        "-devel" packages are installed. For example, if you see errors
        about not having a PNG or JPEG library you must install the "-devel"
        packages of those libraries as needed:

            urpmi libjpeg62-devel libpng3-devel

        If you get some weird error in build about not having "intl.la" then
        make sure you have the gettext packages installed :

            urpmi gettext-devel

    *   Apache Restart

        For most Linux distros where you use the built-in apache web server
        use one of these commands to cold restart Apache in Step 11 :

          service httpd stop
          service httpd start

        OR

            /path/to/init.d/httpd stop
            /path/to/init.d/httpd start

        For the path try /etc/init.d or /etc/rc.d/init.d.

    *   Apache1

        Warning: Some Linux distributions such as Redhat 6.x install
        mod_perl as a Dynamic Shared Object (DSO). This is known to be
        unstable, especially with Mason. Compile mod_perl statically using
        the method listed above if your distro compiles mod_perl1 using
        DSOs. If you suspect yours is not compiled in, run "httpd -l" and
        see if "mod_perl.c" is listed (it should be).

        OpenSSL is required for a secure (https) server when using apache1.
        OpenSSL is installed by default on most Linux distros.

        You will have to tell the OS to look for the Kerberos libraries used
        in this version of OpenSSL:

            ./configure \
                --with-apache=../apache_1.3.x \
                --disable_rule=SSL_COMPAT
            make C_INCLUDE_PATH=/usr/kerberos/include

        (Thanks to David Martin for this info)

  Fedora / CentOS / Redhat

    Netdisco 0.95 packages are available in the Fedora 11 repositories, and
    the EPEL repositories for RHEL/CentOS 5.

    Newer releases may be available from the package author's website, at
    <http://www.auburn.edu/~gouldwp/netdisco>.

    We expect RPMs for Netdisco 1.0 and its dependencies to appear in the
    Fedora and EPEL repositories in due course.

  Mandrivia Linux

    An RPM is available for Mandrivia Linux, but may be out of date. Please
    check that the RPM for Netdisco 0.95 is marked at least 200611 or newer.

  Debian Linux

    Debian 5.0 (Lenny) contains the Netdisco 0.95 packages and all
    dependencies. Newer releases may be available at
    <http://packages.debian.org/netdisco>.

    We expect packages for Netdisco 1.0 and its dependencies to appear in
    the official repositories for Debian "Squeeze" in due course.

    *   GraphViz

        Jordi Guijarro reported that the version that comes with Woody is
        too old. Install a newer version from source.

  Mandrake Linux 9.1

    Netdisco has been tested with Mandake 9.1

    *   Perl 5.8.1

        Perl 5.8.1 on Mandrake 9.x may be a problem (if you get an "out of
        memory" error, you may need to change to 5.6.1 or 5.8.3+).

    *   Postgres

        Installing Postgres the easy way:

            urpmi postgresql postgresql-devel postgresql-server postgresql-docs

        The files you will need to edit below are in /var/lib/pgsql/data.

        If you lost / don't have install CDs :

        The following line uses an FTP site that has the 9.0 RPMs because I
        lost the CDs. Check the current mirror list at
        <http://www.mandrakelinux.com/en/ftp.php3> and choose a mirror close
        to you.

            urpmi.addmedia ftpsite ftp://mirror.mcs.anl.gov/pub/Mandrake-old/9.0/i586/Mandrake/RPMS \
                with ../base/hdlist.cz

        Now you have to add "--media ftpsite" in each "urpmi" command like
        so :

            urpmi --media ftpsite postgresql postgresql-devel

        Remember this for the Apache setup too.

    *   Apache

        Mandrake 9.1 comes with Apache2. It also has the option of
        installing a version of Apache1/mod_perl on a different port and
        then reverse-proxying it.

        Install Apache1 and Mod_Perl 1 and their development packages :

            urpmi apache-devel-1 mod_perl-devel-1 apache-mod_perl-1 mod_perl-common-1

        Mandrake 9.1 - Do this for the DB_File Perl module

            ln -s /usr/include/db1/* /usr/include
            ln -s /usr/lib/libdb1.so.2 /usr/lib/libdb.so

        Configure Both Apaches:

        Mandrake and some Redhats come with two copies of Apache installed.
        The mod_perl server sits on a weird port and is reversed proxied by
        a normal Apache server.

        Mandrake 9.0 uses two Apache1 servers, while Mandrake 9.1 uses an
        Apache2 server that sits in front of the apache1/mod_perl server.

        Configuration files for Mandrake live in /etc/httpd/conf

        In the file httpd-perl.conf add the two "Include" lines:

            Include /usr/local/netdisco/netdisco_apache.conf
            Include /usr/local/netdisco/netdisco_apache_dir.conf

        In the file httpd.conf (httpd2.conf for 9.1) add the final
        "RewriteRule" line:

            <IfModule mod_rewrite.c>
            RewriteEngine on
            RewriteRule ^proxy:.*  -  [F]
            RewriteRule ^(.*\/perl\/.*)$  http://%{HTTP_HOST}:8200$1 [P]
            RewriteRule ^(.*\/cgi-perl\/.*)$  http://%{HTTP_HOST}:8200$1 [P]
            RewriteRule ^(.*\/netdisco\/.*)$  http://%{HTTP_HOST}:8200$1 [P]
            </IfModule>

        In the file commonhttpd.conf add the Alias line :

            Alias /netdisco /netdisco/

        Restart Apache.

            /etc/rc.d/init.d/httpd restart

  Solaris

    See <http://www.saintmarys.edu/~dmckeown/netdisco_solaris10.htm> for a
    great document on getting Netdisco 0.94 to work with Solaris 10.

    *   Make

        Anywhere in this document you see a reference to make you should run
        gmake.

    *   GraphViz

        Make the JPEG and EXPAT libraries first and when making the JPEG
        library make sure you have

            ./configure --enabled-shared --enabled-static

SUCCESS

    Now that you have spent ten hours of your life installing this go drink
    a Beer, you deserve it.

    Once you have or have not succeeded, come join the Netdisco User's
    mailing list at <http://netdisco.org> and pass on any hints you may have
    in the INSTALL process. It's a good place to keep up on new features and
    releases, and it's the place to ask any questions.

    The developers are now maintaining a registry of Netdisco installs. This
    is mainly for morale boosting purposes, but also helps us direct feature
    requests to our target audience. One drawback of the Source Forge system
    is that we have no idea how many people are using the software compared
    to the number of downloads. So after you have Netdisco up and running
    please spend a minute to let us know you're using it at
    <http://netdisco.org/register.html>.
