I have set up the NFS Service using these instructions and it was working fine last week but today I get this error:
Root-NFS: Unable to get nfsd port number from server, using default
I restarted the NFS server like this:
sudo /etc/init.d/nfs-kernel-server restart
and tried repeatedly but still get the error. When I google the error I see the suggestion
update firewall to pass NFS traffic
How do I update firewall to pass NFS traffic? Or should it be some other issue since it was working fine last week?
