<A NAME="Introduction"></A>Introduction</H2>
<B>Mirror</B> is a package written in <B><A HREF="http://www.perl.com/">Perl</A></B>
that uses the FTP<A HREF="http://sunsite.org.uk/rfc/rfc959.txt"> protocol
</A>to duplicate a directory hierarchy between the machine it is run on
and a remote host. It avoids copying files unnecessarily by comparing the
file time-stamps and file sizes before transferring. Amongst other things,
it can optionally rename, compress, gzip, and split files.

<P><B>Mirror</B> was written by <A HREF="http://sunsite.org.uk/~lmjm/">Lee
McLoughlin</A> &lt;<A HREF="mailto:lmjm@icparc.ic.ac.uk">lmjm@icparc.ic.ac.uk</A>>
for use by archive maintainers but can be used by anyone wanting to transfer
a lot of files via FTP.&nbsp; Although originally only available on Un*x
with version 2.9 <B>mirror</B> will also run on Wind*ws 95 and Wind*ws
NT.
<BR>&nbsp;

<P>The latest version of <B>mirror</B> can always be found at either:

<UL><TT><FONT SIZE=+1><A HREF="http://sunsite.org.uk/packages/mirror/mirror-guide.html">http://sunsite.org.uk/packages/mirror/</A></FONT></TT></UL>

<H2>
<A NAME="Description"></A>Description</H2>
<B>Mirror</B> is called in one of two ways (see also mirror master):
<UL>
<PRE><TT><FONT SIZE=+1>mirror [flags] <A HREF="#-g">-g</A>site:pathname</FONT></TT></PRE>

<PRE><TT><FONT SIZE=+1>mirror [flags] [<A HREF="#Package Files">package-files</A>]</FONT></TT></PRE>
</UL>
The first method is used to retrieve a remote file or directory into the
current directory. If you are mirroring a directory it is best to end the
pathname in a slash ('/') as this makes the remote recursive listing smaller
or use the <B><A HREF="#-r">-r</A></B> flag to suppress recursion (see
<B><A HREF="#-g">-g</A></B> below). The <B><A HREF="#Setting Defaults">mirror.defaults</A></B>
file is not used.

<P>In the second method given above, a minimal number of arguments are
required and <B>mirror</B> is controlled by <B><I><A HREF="#Keywords">keyword=value</A></I></B>
lines read from the package files.&nbsp;<A NAME="Finding Defaults"></A>If
a file named <B><A HREF="#Setting Defaults">mirror.defaults</A></B> is
found in either the directory containing the <B>mirror</B> executable or
in the <B>PERLLIB</B> path, then it is loaded before any of the <TT><FONT SIZE=+1>package-files</FONT></TT>.&nbsp;
<B><A HREF="#Setting Defaults">mirror.defaults</A></B> normally just contains&nbsp;
the package of keyword settings called <B><I><A HREF="#Setting Defaults">defaults</A></I></B>
that is used to provide common defaults for all <TT><FONT SIZE=+1>package-files</FONT></TT>.&nbsp;&nbsp;
If no <B><A HREF="#Setting Defaults">mirror.defaults</A></B> file is found&nbsp;
the <A HREF="#Keywords">default settings</A> built into <B>mirror&nbsp;</B>
are used.

<P>Each <TT><FONT SIZE=+1><A HREF="#Package Files">package-files</A></FONT></TT>
is read in turn, looking for named <A HREF="#Package Files">packages</A>.&nbsp;
If the package is not named <B><I><A HREF="#Setting Defaults">defaults</A></I>,</B>
then <B>mirror</B> will perform the following steps.

<P>If <B>mirror</B> is already connected to a site, other than the target
site, it will disconnect from the site.&nbsp; It then changes to the given
local directory, creating it if necessary, and scans it to get the details
of the local files that are already there.&nbsp; <B>Mirror</B> then attempts
to connect to the remote site's FTP daemon. It will then login using the
given <B><I><A HREF="#remote_user">remote_user</A></I></B> and <B><I><A HREF="#remote_password">remote_password</A></I></B>.&nbsp;
The remote directory is then scanned. <B>Mirror</B> does this by changing
to the remote directory (<B><I><A HREF="#remote_dir">remote_dir</A></I></B>)
and running the FTP LIST command, passing the <B><I><A HREF="#flags_recursive">flags_recursive</A></I></B>&nbsp;
or <B><I><A HREF="#flags_nonrecursive">flags_nonrecursive</A></I></B> options
depending on the value of <B><I><A HREF="#recursive">recursive</A></I></B>.&nbsp;
Alternatively a file containing the directory listing may be retrieved
(see <B><I><A HREF="#ls_lR_file">ls_lR_file</A></I></B> and <B><I><A HREF="#local_ls_lR_file">local_ls_lR_file</A></I></B>)
. Each remote pathname will have any required mappings performed on it
to create a local pathname. Then any checks specified by the <I><B><A HREF="#exclude_patt">exclude_patt</A></B>,</I>
<B><I><A HREF="#max_days">max_days</A></I></B>, <B><I><A HREF="#get_newer">get_newer</A></I></B>
and <B><I><A HREF="#get_size_change">get_size_change</A> </I></B>keywords
are applied to names of files or symlinks. <B><I><A HREF="#max_days">max_days</A></I></B>,
<B><I><A HREF="#get_newer">get_newer</A></I></B> and <B><I><A HREF="#get_size_change">get_size_change</A>&nbsp;
</I></B>are not applied to directories.&nbsp; This creates a list of all
required remote files and the local pathnames to store them in.

<P>Local versions of all required directories are then created.&nbsp; Then
all required files are fetched from the remote site into their local pathnames.
This is done by retrieving the file into a <A HREF="#Temporary Filenames">temporary
file</A> in the target directory. The transfer is normally done in binary
mode (see <B><I><A HREF="#vms_xfer_text">vms_xfer_text</A></I></B>).&nbsp;
If required the temporary file may be <A HREF="#File Compression">compressed,
gzip'ed</A> or <A HREF="#File Splitting">split</A>. The file's time-stamps
are reset to match those of the remote file.&nbsp; Finally the temporary
file is renamed to have the correct name.

<P>Once all files have been transferred any required symbolic links are
created (where support by your Operating System) and any unnecessary pathnames
in the mirror are <A HREF="#File Deletion">deleted</A>.

<P>Unless an internal failure is detected, any error will cause the current
package to be skipped and the next one tried.

<P><B>Mirror</B> can handle symbolic links but not hard links. It does
not duplicate owner or group information as usually this is meaningless
over a network (but see <B><I><A HREF="#user">user</A></I></B> and <B><I><A HREF="#group">group</A></I></B>).
If you require any of these options and you are on Un*x use <B>rdist(1)</B>
instead.

<P><B>Mirror</B> was written to mirror remote Un*x archives, but has grown
(like topsy).
<H2>
<A NAME="Flags"></A>Flags</H2>
Although <B>mirror</B> has a large number of command line flags most should
only really be used when doing a very simple mirror as a one-time event.&nbsp;
If you intend to maintain a mirror area it is much better to put all the
details into a <B>mirror</B> <A HREF="#Package Files">package</A> file
and then run <B>mirror</B> on that file.

<P>The only flags you should use often are <B><A HREF="#-n">-n</A></B>
and, if you like to see what mirror is up to,<B><A HREF="#-d">-d</A></B>.

</TABLE>

<H2>
<A NAME="Package Files"></A>Package Files</H2>
Each group of keywords defines how to mirror a particular package and should
begin with a unique <B><I><A HREF="#package">package</A></I></B> line.
The package name is used in report generation and by the <B><A HREF="#-p">-p</A></B>
argument, so pick something mnemonic. The minimum needed for each package
is <B><I><A HREF="#package">package</A></I></B>, <B><I><A HREF="#site">site</A></I></B>,
<B><I><A HREF="#remote_dir">remote_dir</A></I></B> and <B><I><A HREF="#local_dir">local_dir</A></I></B>
. On finding a <B><I><A HREF="#package">package</A></I></B> line, all the
default values are reset to either the values from the <B><I><A HREF="#Setting Defaults">defaults</A></I></B>
package (or built-in values if defaults has not been set).&nbsp; A package
ends at either the next <B><I><A HREF="#package">package</A></I></B> statement
or at the end of file.

<P>Package files are parsed as a series of statements. Blank lines and
lines beginning with a hash are ignored. Each statement is of the form
<UL><B><I>keyword</I>=value</B></UL>
or
<UL><B><I>keyword</I>+value</B></UL>
&nbsp;You can add whitespace before the keyword and the equals/plus. Everything
immediately following the equals/plus is the value, including any leading
or trailing whitespace. The equals version sets the keyword to this value,
while the plus version concatenates the value onto the end of the existing
value (normally set in <B><I><A HREF="#Setting Defaults">defaults</A></I></B>
package).

<P>A statement can be continued over multiple lines by ending all lines
except the last, with the character ampersand ('&amp;'). The line following
the ampersand, is appended to the current line with all leading whitespace
removed.

<P>Although there are a lot of keywords that can be set, the built-in defaults
will handle most cases. Normally only <B><I><A HREF="#package">package</A></I></B>,&nbsp;
<B><I><A HREF="#site">site</A></I></B>,&nbsp; <B><I><A HREF="#remote_dir">remote_dir</A></I></B>
and <B><I><A HREF="#local_dir">local_dir</A></I></B> need to be set.
<H3>
<A NAME="Setting Defaults"></A>Setting Defaults</H3>
If the package name is <B>defaults</B>, then no site is contacted, but
the default values given for any keywords are changed. Normally all the
defaults are in the file <B>mirror.defaults</B> which will be automatically
loaded before any <A HREF="#Package Files">package files</A> (see <A HREF="#Finding Defaults">Description</A>).

daemons using a standard <B>ls</B> command. To use a Un*x host with a non-standard
<B>ls</B> or a non Un*x host it is necessary to set the <B><I><A HREF="#remote_fs">remote_fs</A></I></B>

<A NAME="Temporary Filenames"></A>Temporary Filenames</H2>
By default when mirror creates a temporary filename it takes the real filename
and puts <B><TT><FONT SIZE=+1>.in.</FONT></TT></B> at the start.
<BR>If your system limits the length of a filename a lot (some older Un*xes
were limited to 14 characters) then look for:
<PRE>&nbsp; <TT>LIMITED NAMELEN</TT></PRE>
which is about 75% of the way through mirror.pl, for a note on how to reduce
temporary filename length.&nbsp; I only know of one site using this.
<H2>
<A NAME="Regular Expressions"></A>Regular Expressions</H2>
This is a short explanation of regular expressions.&nbsp; For a more comprehensive
guide see the <B>Perl</B> manual pages or the O'Reilly book "Mastering
Regular Expressions".

<P>A regular expression, or regexp, is a way of using matching patterns
in text strings.&nbsp; For example the regexp:
<UL>
<PRE>&nbsp;^s</PRE>
</UL>
would match any string that begins with an <B><TT><FONT SIZE=+1>s</FONT></TT></B>.&nbsp;
The <B><TT><FONT SIZE=+1>^</FONT></TT></B> is a special character that
means <I>beginning of string</I>.&nbsp; There are a number of specials
possible in a regexp, everything that is not special is taken as a literal
character, such as the <B><TT><FONT SIZE=+1>s</FONT></TT></B> in the example
above.&nbsp; To turn off a special character put a backslash, <B><TT><FONT SIZE=+1>\</FONT></TT></B>,
in front of it.&nbsp; This only effects the special character immediately
following it.

<P>A word of warning: although very similar to Un*x shell (and D*S COMMAND)
wildcards there are differences.&nbsp; For example any Un*x and D*S would
treat *.ZIP as any filename ending in .ZIP, *.ZIP as a regular expression
is an error!&nbsp; The * is special that must follow something (see below).

<A NAME="Hints"></A>Hints</H2>
When adding a new package, first test it by running <B>mirror</B> with
the <B><A HREF="#-n">-n</A></B> option.

<P>If you are adding to an existing archive that was not created by <B>mirror</B>
(perhaps you copied the files from a CDROM) then it is usually best to
force the time-stamps of the existing local files so time comparisons with
the remote files show the files as identical (see <B><A HREF="#-T">-T</A></B>).

<P>Try and keep all packages that are being retrieved from the same site
together in the same <A HREF="#Package Files">package file</A>. That way
<B>mirror</B> will only have to login once.

<P>Remember that all regexp's are <B>Perl</B> regular expressions.

<P>If the remote site contains symlinks that you want to "flatten out"
into the corresponding files, then do this by changing the flags passed
to the remote <B>ls</B> which will be either <B><I><A HREF="#flags_recursive">flags_recursive</A></I></B>
or <B><I><A HREF="#flags_nonrecursive">flags_nonrecursive</A></I></B> to
include <B><I>L</I></B>&nbsp; First test this by trying a <B>ls -lRatL</B>
on the remote site under the FTP command to check whether the remote filestore
has any symlink loops.&nbsp;&nbsp; These cause ls to go into an infinite
loop - if this happens you will have to talk to the manager of the remote
area about removing them.

<P>If you are mirroring a very large site that changes infrequently, add
<B><I><A HREF="#max_days">max_days</A>=7</I></B> to the settings <B>after</B>
it is initially mirrored. That way <B>mirror</B> will only have to consider
recent files when updating. Then once a week, or whenever necessary, call
<B>mirror</B> with <B><A HREF="#-k">-k </A><I><A HREF="#max_days">max_days</A>=0
</I></B>to force a full update.

<P>If you don't want to compress anything from the remote site the easiest
way to do this is to set the <B><I><A HREF="#compress_patt">compress_patt</A></I></B>
to nothing.

<P>If you want to run a command at the end of mirroring a package a useful
trick is to reset the <B><I><A HREF="#mail_prog">mail_prog</A></I></B>
variable to be the program name and <B><I><A HREF="#mail_to">mail_to</A></I></B>
to be the arguments.

<P>For netware, dosftp, macos and VMS you should normally set <B><I><A HREF="#remote_dir">remote_dir</A></I></B>
to be the home directory of the remote FTP daemon. Connect in manually
and before changing directory use the pwd command to find where home is.
If you are only mirroring part of the tree then give the full pathname
including this home directory at the start.

<P>macos names can sometimes contain characters that make it hard to pass
them through Un*x shells. Since compressing files is done via a shell it
would be best to turn off compression with <B><I><A HREF="#compress_patt">compress_patt</A>=</I></B>

<P>macos files seem to always change size when transfered, in either binary
or text mode. So it would be best to set get_size_change=false
<H2>
<A NAME="Netiquette"></A>Netiquette</H2>
If you are going to mirror a remote site, please obey any restrictions
that the site administrators place on access. You can generally find the
restrictions on connecting to the archive using the standard FTP command.
Any restrictions are normally given as a login banner or in a (hopefully)
obvious file.

<P>Here are, what I hope are, some good general rules:

<P>You should probably get permission from the remote site <B>before</B>
setting up a mirror of it.&nbsp; Some sites require detailed logs.&nbsp;
Unauthorised mirrors would take traffic from the site generating the logs
and so ruin their statistics.&nbsp; There may also be <B>SERIOUS LEGAL
REASONS</B> why mirrors are unwanted.

<P>Only mirror a site well outside the working hours of both the local
and remote sites.

<P>It is probably unfriendly to try to mirror a remote site more than once
a day.

<P>Before trying to mirror a remote site, try and find the packages you
want from local archives, as no one will be pleased if you soak up a lot
of network bandwidth needlessly.

<P>If you have a local archive, then tell people about it so they don't
have to waste bandwidth and CPU at the remote site.

<P>Do remember to check your package-files from time to time in case the
remote archive has changed their access restrictions.
<BR>&nbsp;
<H2>
<A NAME="Bugs"></A>Bugs</H2>
Some of the netiquette guidelines should be enforced.

<P>Should be able to cope with links as well as symlinks.

<P>Suffers from creeping featurism. (Actually more like galloping featurism!.)

<P>If you are using Perl 4 (Perl 5 users skip this):
<UL>If h2ph has been run for your system then you should probably remove
the socket.ph shipped with mirror and use the one <I>meant</I> for your
machine.&nbsp; If h2ph has not been run then you should persuade your systems
administrators to do so.&nbsp; The contents of socket.ph are operating
system specific and it is possible that what works for me will not work
for you.

<P>A special note for Solaris 2.x users.&nbsp; The socket.ph created by
h2ph doesn't work.&nbsp; Install the socket.ph-solaris from this distribution
instead.</UL>


<P>There seems to be a problem with older versions of Perl that causes
mirror to fail with the message 'fstype unix unknown'.&nbsp; If you experience
<BR>this then please upgrade your Perl to 5.004 or better.
