hello All
I have rhel5 server and rhel4 ,rhel5 as client ok
I install NFS server on the server 192.168.0.2 and in the /etc/exports file /home 192.168.0.0/255.255.255.0(rw.sync)
/nfs_share 192.168.0.0/255.255.255.0(rw.sync)
and Add 2049 like tcp , udp in my firewall and 111 like tcp(for portmap)
and iptables -L it's see me it's listing for all port need
and every thing it's good at now and try to mount user from server system and it's good

but when I try to mount from client's PC like rhel4 , rhel5 it's not all
time can be mount and when it's Don't upper message retry again
just and in /var/log/message no any comment or log for what's happend for
this message like if my firewall it's deny or reject the request for mount NFS folder on the server


when I'm try all steps on my rhel4 server it's work and no any problem
and it's very fast

I think my problem with SELinux but I'm don't know where is it
please if any body have any idea for this problem
I will be very thanks for he http://linuxquestions.cachefly.net/i...s_lq/icon7.gif

Have you tried to disable the SELinux to see if the problem lies with it?

Yes When I disable the SELinux it's work
my Problem in his but not in his log for SELinux or /var/log/messages
it's upper that any deny my nfs_client request

I have no experience about SELinux so I'm not able to help you out here further.

Check out the SELinux documentation and try to create rules to allow NFS mounts.
