Hi,

NFS server is not working in client side and getting the following error while mounting the remote..

[root@localhost ~]# mount -t nfs 192.168.50.5:/home/samb/rncit /var/log/logs

all the services is running and restarted several times.

can any one explain what is wrong with this?

Thanks in Advance

It appears that rpcbind is not running which starts as a separate service from nfs.

Here it is

Make sure the firewall on the server knows to permit NFS and rpcbind.

You might also need to check the SELinux boolean flags to permit NFS exports (you can check with "getsebool -a | grep -i nfs", then select the ones you want/need.

Here the output
[root@localhost ~]# getsebool -a | grep -i nfs
allow_ftpd_use_nfs --> off
allow_nfsd_anon_write --> off
cobbler_use_nfs --> off
git_system_use_nfs --> off
httpd_use_nfs --> off
nfs_export_all_ro --> on
nfs_export_all_rw --> on
qemu_use_nfs --> on
samba_share_nfs --> off
use_nfs_home_dirs --> on
virt_use_nfs --> off
xen_use_nfs --> off

It seems nothing is blocked. Is there another way to proceed for the same?

Looks at "iptables -L" and see if there's a firewall rule preventing NFS traffic.

Finally I got the solution. it was missing with RPCBIND.

thanks for help.

Well done.
