The NFS server needs some rpc services in addition to nfs proper, such as mountd, statd, lockd and rquotad. NFS proper runs on port 2049. What ports do you suppose the rpc services run on? Believe it or not, by default, these are assigned random ports when those services are started (when you start nfs). To see what they happen to be, run rpcinfo as root on the nfs server: rpcinfo -p If you stop/start the nfs server you'll see different ports. At any rate, you need to open these ports in the firewall. First you force them to be non-random, by specifying what you want them to be in /etc/sysconfig/nfs. For instance RQUOTAD_PORT=4000 LOCKD_TCPPORT=4001 LOCKD_UDPPORT=4001 MOUNTD_PORT=4002 STATD_PORT=4003 Once you've pinned them down, you open them in the firewall (on the nfs server) once and for all. Furthermore, you need to open the portmapper in the firewall as well (i.e. port 111 both tcp and udp). The portmapper is needed to tell the nfs clients what the rpc ports are. That's all. One more thing. You don't need to put anything in /etc/fstab unless you want the exported partitions to be mounted permanently on the clients. Run the automounter on the clients, and then the exported partitions get mounted on demand. Ex. on a client cd /net/my_nfs_server/my_exported_partition mounts it first, then changes directory.
