Re: Prior to login, where can I put a message

Hi,

for telnet connections you can put text into the file /etc/issue
This will be shown before login.

Regards

Thanks, I also remembered that I can also put the message in /etc/motd. We're all getting into security messages all over the place. Thanks

Re: Prior to login, where can I put a message

/etc/motd is only displayed after a successful login. Prior to login, the file /etc/issue is displayed. It is the location for all your warnings about improper access to your system. Note also that you'll need to add not only -b /etc/issue to telnetd in /etc/inted.conf, you should also add -B /etc/issue to the rlogind line.

However, to keep with modern security standards, both telnet and the "r" commands (remsh, rcp, rlogin, rexec) should be disabled and SSH2 used in it's place.

Re: Prior to login, where can I put a message

Hi,

Any banner message in /etc/motd is displayed on a direct connected login session (Login session on console and serial ttys, modem getty sessions). You can also use the same file as a banner for telnet user. For this edit the /etc/inetd.conf file and add the banner option in the telnetd line. Take a look at this thread from ITRC on how to do that,

The itrc doc id is KBRC00001633.

Hope this helps.
