This is netkit-rsh-0.17 for Linux.
This package updates netkit-rsh-0.16.1.
If you're reading this off a CD, go right away and check the net
archives for later versions and security fixes. As of this writing the
home site for NetKit is
ftp://ftp.uk.linux.org/pub/linux/Networking/netkit
Contents:
rexec Password-based remote execution program
rsh Non-password-based remote execution program
rcp Remote copy program using rsh
rlogin Remote login program
rshd Daemon for rsh connections
rexecd Daemon for rexec connections
rlogind Daemon for rlogin connections
Note: None of these programs provide encryption or strong
authentication of network connections. As such, their use is
discouraged. The "ssh" protocol and package is a cryptographically
secure replacement.
Requires:
Working compiler, libc, and kernel, and a recent ncurses or
libtermcap.
Security:
This release contains no security fixes relative to
netkit-rsh-0.16. However, as noted above, all programs in this
package are inherently insecure except on trusted networks.
They should not be used at all except with great caution.
This package is maintained chiefly for the sake of compatibility.
Note: do not rely on the behavior of the options that limit
the use of .rhosts or /etc/hosts.equiv without testing them, as
some of them depend on undocumented libc interfaces that may not
work correctly on all systems.
Versions of these programs prior to netkit-rsh-0.10 should not
be used.
WARNING: The PAM support in this version may be screwed up. If
you use PAM, please be sure to double- and triple-check the
behavior of rshd, rlogind, and rexecd to make sure they don't
inadvertently grant access when it should be denied. If in doubt,
get the SRPMs from Red Hat and use their sources instead.
Installation:
Do "./configure --help" and decide what options you want. The
defaults should be suitable for most Linux systems. Then run
the configure script.
Do "make" to compile.
Then (as root) do "make install".
Save a backup copy of any mission-critical program in case the
new one doesn't work, and so forth. We warned you.
If you get gcc warnings from files in /usr/include, they are
due to problems in your libc, not netkit. (You may only see
them when compiling netkit because netkit turns on a lot of
compiler warnings.)
DEC CC:
The DEC compiler for the Alpha is now freely available. This
is a much better compiler with gcc, that is, it generates much
better code. If you have the DEC compiler, you can explicitly
use the DEC compiler instead of gcc by configuring like this:
./configure --with-c-compiler=ccc
It is known to generate spurious warnings on some files. Also,
some headers from some versions of glibc confuse it; that may
prevent netkit from working. Other problems should be reported
as bugs.
Bugs:
Please make sure the header files in /usr/include match the
libc version installed in /lib and /usr/lib. If you have weird
problems this is the most likely culprit.
Also, before reporting a bug, be sure you're working with the
latest version.
If something doesn't compile for you, fix it and send diffs.
If you can't, send the compiler's error output.
If it compiles but doesn't work, send as complete a bug report as
you can. Patches and fixes are welcome, as long as you describe
adequately what they're supposed to fix. Please, one patch per
distinct fix. Please do NOT send the whole archive back or
reindent the source.
Be sure to send all correspondence in e-mail to the netkit address.
Postings to netnews or mailing lists will not be seen due to the
enormous volume. Also, anything that doesn't get filed in the bug
database is quite likely to end up forgotten.
Please don't report known bugs (see the BUGS file(s)) unless you
are including fixes. :-)
Mail should be sent to: netbug@ftp.uk.linux.org
Early in April 2000, a hacker broke into the machine that was hosting
the netkit bug database for me and trashed it. Unfortunately, it seems
backups hadn't gotten done for a while, so three months of mail (since
mid-January) was lost. So, if you sent something and didn't hear back,
or you sent something, heard back, but the changes failed to appear in
this release (unlikely but possible) - please resend.
Please see http://www.hcs.harvard.edu/~dholland/computers/netkit.html
if you are curious why it was so long between the 0.10 and 0.16 releases.
Future plans for netkit maintenance are still up in the air, but in the
meantime new releases will still appear from time to time. I don't have
a whole lot of cycles to spare to work on netkit, so things are likely
to continue to be fairly slow.
