Hi, I got an issue with NFS shares after latest upgrade :
I have two PCs that both run Ubuntu Breezy
192.168.1.102 Server
192.168.1.106 Client
One is NFS sever with two shares
here is a /etc/exports:

#/etc/exports: the access control list for filesystems which may be exported
# to NFS clients. See exports(5).
/home/alex/ 192.168.1.106(rw,sync)

/usr/backups/ 192.168.1.106(rw,sync)

Both shares have same owner and permissions, I can mount first share just fine on the client machine, second share I get:
mount 192.168.1.102:/usr/backups/ failed, reason given by server: Permission denied

Even more I can not ping my client from the server, I get destination host unreachable error. I cannot ssh into client from server with the same error, but I can ssh into server from the client, then while still logged in through ssh I can ping and ssh back into the client with no problems. Still can't mount second share though. Also I have an XP box that pings both ways with client and server without any issues. Any takers?

What is the permissions on /usr/backups?
Make them the same as /home/alex. Do something like this.
chown -R alex /usr/backups
ghgrp -R alex /usr/backups

and if needed

chown -R 777 /usr/backups

Restart nfs service after changes.

All permissions and owners are exactly the same.

Problem solved! This might sound weird, but on the client pc I have a wireless interface that was picking up neighbors wireless router which assigned it the same address as my server (192.168.1.102). When I mounted first nfs share it mounted /home/alex which is the same on the client and server, since client doesn't have second share I was getting permission denied. What strange that even after I disabled my wireless card, ifconfig was showing ip address of 192.168.1.106 but everything else was still mapping into 192.168.1.102. So when I tried to connect via ssh I connected back to the same PC.
