NFS between two FC4 machines
Doug Laidlaw Actually, it's not a bad idea. If you are a Linux user shopping for a NIC card, you probably know that the driver already exists or can be easily found...
I used the RHEL SysAdmin manual to set up NFS between two FC4 machines:
I think it's definitely a firewall problem, because NFS with automount works fine when I turn off the firewall on the server. However, with the firewall on, I get an error, e.g. :
mount clntudpcreate: RPC: Port mapper failure - RPC: Unable to receive
Let's not forget 'cpio'. :-) The simple "cp -au" method will work just fine with any reasonably modern implementation of 'cp', and it will automatically handle sparse files...
Of course, nothing can be mounted.
On the server, I do have 2049 udp and tcp open:
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 2049 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 2049 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.1.0-255.255.255.0 -p tcp -m tcp --dport 111 -j ACCEPT
-A RH-Firewall-1-INPUT -s 192.168.1.0-255.255.255.0 -p udp -m udp --dport 111 -j ACCEPT
What do I have to do to get this to work? Also, how can I even tell if I'm running nfs3 or 4? The NFS howto describes nfs3, and I'm not sure if I should trust it. It says I have to bind statd, mountd, etc. to certain ports, and open them in the firewall, but the manual doesn't mention anything besides port 2049.
Thanks!
