nfs RPC timed out error

well i configured nfs so that 6 systems may automatically
mount the dir from that nfs server by properly editing the /etc/fstab file and the /etc/exports file

now all my systems are able to automount the nfs partion

but one system does not automount it nor does it mount the partition manually

 - it just shows " RPC time out"

the systems pinging to all others and there is not network problem,
rpm query indicates that nfs-utils is installed.

what exactly is the problem with that system

any help will be appreciated

just to isolate the problem a bit more:

Are you sure you are not running any packet-filtering rules on that particular machine? i had the same problem a long time ago and it turned out to be an ip-tables configuration which i was not even aware of at that time...;-)

i had the same problem and i posted at various places, didnt get an answer, i reinstalled redhat with v8 instead of v7.3 and i configured it according to a redhat configuration book

and i can mount it from my own computer but i go over to my father's computer in linux and i type mount -t nfs /mnt/nfsdir and it says RPC: Time Out
i have just about every service running i allow everyone in /etc/hosts.allow and nothing in /etc/hosts.deny(just for testing possible causes) i dont have any packet filtering and it still doesnt work

Thanks a lot Martijn for your help

   as per your instructions i checked the firewall configuration of that system and found it in high security mode.

  i customised it and selected the only required services.

then i manually mounted nfs  - successfully!

   i restarted the machine and now it mounting it automatically

thanks again for your timely help

keep up the good work
