NFS

(This is still too brief)

NFS Configuration

• You need an /etc/exports to tell what should be exported
• Need to edit the /etc/sysconfig/nfs file to pin the ports (see iptables)
• Need to set "nfs" and "nfslock" to start automatically for runlevels 3,5

To check what ports NFS is using issue an

rpcinfo -p localhost

A full restart of the nfs related system

service portmap restart
service nfs restart
service rpcsvcgssd restart

Issues

Occasionally, issues crop up due to network-mounted home directories. Some applications, like firefox, don't behave properly. It seems to strike everyone at once when it does, and the solution so far has been to restart the nfs service. CIS has related issues with their CIFS-based home directories.
