Problems exporting partitions via NFS

[don fisher]

I have three systems, two Ubuntu and one F14. I am trying to move to 
F14. Currently I can mount any of the Ubuntu the systems on the three 
computers. But when I try to mount the file system exported from F14 I 
receive a message from NFS:

mount.nfs: No route to host

I can ping the F14 system, so the name resolution should be ok. I use 
the same /etc/exports file on all machines, so is is probably not the 
problem.

Is there anything I need to set up with iptables, or PAM?

I am working from the command line. Any advice appreciated.

Thanks

Have you adjusted your firewall (iptables) in F14 to allow NFS?

Thanks. I turned off iptables using system-config-services and was able 
to mount the system remotely. The addition of nsf4 in the fstab did no 
appear to be required.

Thanks again. Now I have to relearn how to edit iptables:-)

Just use system-config-firewall. It's pretty simple.

This isn't the old "NFS uses random ports" issue, that required
configuring NFS to use fixed ports?

I had similar problems in mounting from fstab.  It turned out that I was using 
mount commands suited to nfs3 and Fedora was using nfs4.  This is one of the 
fstab lines that works for me - I'm sure that from that you can find what you 
need.

192.168.0.xx:/home /mnt/server_home nfs4 rsize=8192,wsize=8192,timeo=14,intr
