Managers,
Thanks for all the replies! I got what I needed ASAP! Here
was my original question:
Is there anyway to display a warning banner to the login
screen _before_ the telnet login prompt on a 2.x and a
4.1.x system?
I tried /etc/issue but that only seems to work on the console
and serial tty ports.
The overwhelming majority said to use an in.telnetd wrapper, such
as the example from Tim Wort <tim@Access.COM> below:
The best way I have seen to do this is to replace the line in /etc/inetd.conf
that starts in.telnetd with a script. (works with SunOS 4.x and 5.x)
The line will look like:
telnet stream tcp nowait root /usr/etc/in.telnetd in.telnetd
with something like:
telnet stream tcp nowait root /usr/script/banner.sh in.telnetd
The script will look like:
---------------------------------------
#!/bin/sh
cat << EOF
This is the line to display.
EOF
exec /usr/etc/in.telnetd
---------------------------------------
That is what I did and it works fine. I actually needed this done
on a 4.1.3 system running the TIS Firewall Toolkit. So, I just
-exec'd the telnetd wrapper script out of netperm-table and it worked
fine.
Several people mentioned that the latest version of tcp_wrappers (tcpd)
has this functionality built in. Some also mentioned to change /bin/login
to a wrapper that displays the banner message then execs /bin/login.
Also, /etc/issue will display a banner but only on a Solaris 2.4 system.
I tried on both a Solaris 2.3 and 4.1.3 system with no luck, evidentally
/etc/issue only works for tty ports and console.
I can email the entire message digest if anyone is interested.
