Don't let system issue file to be displayed You should not display your system issue file when people log in remotely
. To do this, you can change the telnet option in your "/etc/inetd.conf".
To do this change the line in "/etc/inetd.conf":


telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd
to look like:
telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd -h Adding the "-h" flag on the end will cause the daemon to not display any
system information and just hit the user with a login: prompt. I will
recommend to use sshd instead.

I find it ironic that in a discussion regarding linux security you mention having telnetd enabled. These days I'm sure most (all?) distro's ship with telnetd disabled, and IMHO that's the way it should stay.
