NFS mount error

Hello All,

 I am sorry to bother you, but I am not able to find a solution to this problem. I have setup a new server in the lab and I have connected one external storage to this server. I want to export this filesystem as NFS to other servers.

I have followed all the instruction in this website NFS HOWTO: Setting up a NFS server

Now I am not able to mount the nfs system on client, it throwing this error mount: mount to NFS server ‘msvlsi65.ecen.okstate.edu’ failed: System Error: Connection refused.

I have disabled firewall in the server and I have checked the hosts.allow and also hosts.deny.

Any suggestions from your side would be great.

For further details, here is the output of rpcinfo -p

100000    2   tcp    111  portmapper
100005    1   udp  32775  mountd

100024    1   udp  32777  status
100024    1   tcp  32939  status

There were 2 portmapper that was running previously, one UDP and one tcp. But after the reboot udp is missing. I tried to restart the service, but no luck. Do you think this may be the problem or something else.

Also ping is working absolutely fine. I can login through ssh from one to another.


Thanks,
Giridhar

Check the firewall and make sure that your server can perform a reverse
lookup of the DNS name of the client. (I’ve found the latter is
sometimes necessary - there’s probably an option to disable it but I’ve
never dug that deeply into it).

“connection refused” makes me think it’s a firewall issue.
