While testing server firewall rules and checking traffic between two servers, I noticed some odd udp traffic. It turns out that updatesrv is using ports that it shouldn't be. updatesrv should be listening to the codasrv port, 2432 (as listed in /etc/services), but instead it's listening to these ports: # lsof -P -i -n |grep updatesrv updatesrv 10956 root 3u IPv4 6028190 UDP *:33802 updatesrv 30339 root 5u IPv4 5699700 UDP *:33756 It appears that the ports that updatesrv listens on are completely random and I have no way of knowing what ports to open on my firewall ahead of time. Is this correct? Is there a way to force updatesrv to listen on a particular port? Or is there a range of ports that it will always be listening on? (Note that this is unrelated to the venus masquerade options.) -- Patrick Walsh eSoft Incorporated 303.444.1600 x3350 http://www.esoft.com/Received on 2005-04-26 11:28:15
