I use the firewall logging rules (I assume you don't actually have telnet
open, you just want to know who's knocking?)

There are probably more glorious ways of doing this ... portsentry, etc.

Mine works for me ;-)

/etc/rc.firewall
-----
/sbin/ipfw add deny log tcp from any to {your.ip.num.here} 23 via
{interface}
/sbin/ipfw add deny log udp from any to {your.ip.num.here} 23 via
{interface}
-----

/etc/syslog.conf
-----
!ipfw
*.*             /var/log/ipfw.log
-----

/usr/src/sys/i386/conf/{yourkernel}
-----
options         IPFIREWALL
options         IPFIREWALL_VERBOSE
-----

The resulting ipfw.log looks like:  (them=1.1.1.1  me=2.2.2.2)
-----
Jun 23 11:18:48 ipfw: 300 Deny TCP 1.1.1.1:832 2.2.2.2:23 in via {interface}
Jun 23 11:18:51 ipfw: 300 Deny TCP 1.1.1.1:832 2.2.2.2:23 in via {interface}

Is there a log of, or a way to log any attempts to telnet into your server?
Thanks
