One of the RaQ4's got rebooted today, after applying a few updates.
Portsentry seemed to cause something funky to happen..
In /etc/rc.d/rc.local:
/usr/local/psionic/portsentry/portsentry -tcp
/usr/local/psionic/portsentry/portsentry -udp
Rebooted the machine, ran netstat -ta and it showed every possible service
I could think of as ":LISTEN"
"WTF?" I thought. I kill -9'd portsentry, and ran netstat -ta again. This
time only a few services were showing up. Fired up portsentry by hand, and
it looked normal once again.
I've never seen it do this before. Portsentry is on the rest of the linux
machines (Caldera) and it has never exhibited this odd behavior before.
Anybody else seen this? Good news is that the updates (all of them) seem
to have not adversely affected anything on the unit. It's working fine,
aside from the odd ports.
Oh! If I nmap the box, it shows every port that netstat -ta did as being
open. Restarting portsentry like I did caused the nmap scans to show very
few ports open.
Strange, indeed..
