NFS stopped working
I have a home server connected to several machines in my household. I previously had NFS shares on the server that were available to the other machines. Now when I attempt to mount a server share from a terminal on another machine, it simply "hangs" there until I hit CTRL-C or eventually times out. I am able to "see" the server's samba shares (same directories) and I am able to mount a machine NFS share on the server.
I've tried many things: reboot, re-install the nfs server, try either the kernel or user-space NFS server, diagnose w/ rpcinfo and showmount, etc.
Grasping at straws, the only thing I can think of is that I was also trying to use tos on the server firewall (using firestarter) to prioritize traffic to a wireless router that is also my Vonage voip adapter.
How do I troubleshoot this?! /var/log/messages or ./syslog show nothing relevant, either.
