Re: NFS mount problems

[Jay Leafey <jay.leafey@xxxxxxxxxxxx>]

Part of the problem, as you've found, is trying to get the NFS server to 
use "static" ports in portmapper instead of the more-or-less random 
ports used by default.  Luckily, it's fairly easy to convince the 
different NFS components to do so.  First, look for the file 
/etc/sysconfig/nfs, which controls most of the NFS daemons.  Edit it to 
contain the following:

> #  Force rpc.statd to run on port 4000
> STATD_PORT=4000
> #  Force lock daemon to run on port 4001
> LOCKD_TCPPORT=4001
> LOCKD_UDPPORT=4001
> #  Force mountd to run on port 4002
> MOUNTD_PORT=4002
> #  Force rquotad to run on port 4003
> RQUOTAD_PORT=4003

After restarting all the daemons, or just rebooting the server, the 
rpcinfo command should show all the services using the static ports.

You will then need to open these ports up in iptables to whaterver 
degree you need.  I usually add something like the following lines in 
the appropriate part of the iptables file:

> -A RH-Firewall-1-INPUT -p tcp -m tcp -m state --state NEW -m multiport -s 192.168.1.0/24 --dports 111,2049,4000,4001,4002,4003 -j ACCEPT
> -A RH-Firewall-1-INPUT -p udp -m udp -m state --state NEW -m multiport -s 192.168.1.0/24 --dports 111,2049,4000,4001,4002,4003 -j ACCEPT

This opens up all the ports needed to my local LAN.

It works for me, but your mileage may vary.
