firewalls besides iptables

[Ryan Golhar]

NFS uses RPC.  When the NFS server is rebooted, the ports RPC assigns to
it may change, which is what you are seeing this.

You can fix those ports to use specific ports.  There is a good
explanation of how to do this at

I used this to fix the ports on our server NFS servers.

Subject: firewalls besides iptables


I have opened some ports in iptables on an Enterprise 3 system to allow 
nfs mounting of its partitions on other systems.  When I do an "nmap" 
on this system from a second system, I see that some of the ports that 
I thought I had opened are closed and some are open.

Is there something besides iptables that might be running on the system?
	I did not set up the "problem" system, so I do not know all the
steps 
that were involved in the setup.  Other Enterprise 3 systems that I 
have do have these "closed" ports open.

nfs is not working properly on the first  system.  It does work if I 
stop the iptables services altogether.

The other "strange" thing about the system is that "rpcinfo -p"  shows 
portmapper, rquotad, nfs, mountd and status.  nlockmgr and sgi_fam are 
not present.  Services portmap, nfs and nfslock have been started.
