Portmap problem

Running a RedHat 7.3p network for experimentation purposes at a volunteer position at the
DSHS office where I did my intership. The server has an NFS and SMB server installed. Working on
the NFS side I have setup the NFS exports and hosts files, with help from the forum. Now the
problem is when I have tryed a manual mount of one of the shares from the workstation on the
server I recieve the error: mount: RPC:Portmapper failure- RPC: Unable to recieve. I read the
man page for portmap and put in an entry for portmap for my domain on the server. I still get the same error.
Time to say I need help again.

I suppose you need portmapper (service) on the server. But I'm not sure if you need portmapper at all. How is your NFS configured?

check syslog at server while trying to mount. It will mostly tell you what exactly is happening. ( you can use tail -f /var/log/messages for this )

run this as root on your NFS client:

rpcinfo -p

If you get a portmapper error, your portmap service might not be running. Start it using this:

/sbin/service portmap start
then check your NFS server:

rpcinfo -p server_ip

You can check if you can see the exported shares by running this:

showmount -e server_ip

When I ran rpcinfo -p on the client the output was: 2 entries for portmapper, 2 for status, and 1 for sqi_fam.
The rpcinfo for the server ip gives an error: rpc can't contact portmapper: RPC: Remote system error - Connection refused.
The showmount on the client gives the original error.
I'm beginning to think I should have asked a simpler question:
What needs to be installed on a client to use an NFS servers shares?
An rpcinfo on the server shows the same as the client plus 4 for rquotad, 6 for mountd, 2 for nfs, and 3 for nlockmgr.
The problem seems to be with the server from the output, but what is wrong has me stumped.

I had the same problem with RedHat 7.3. I fixed the problem by reconfig the firewall.

Log in as root and use the commad setup then chose the firewall option.

this should fix it
