rpc.nfsd unable to set any sockets for nfsd

Error: When you install and restart NFS service you will get an error “rpc.nfsd unable to set any sockets for nfsd”

Root cause: This problem may occur due to rpcbind service is not working or the app is not been installed on the server.


1. Check the rpcbind service works perfectly by:- #rpcbinfo -p

2. If it throws an error by “rpcinfo: can’t contact portmapper: RPC: Remote system error – No such file or directory”

3. Then we need to install the rpc package by

3a. # yum install avahi
Installing : libdaemon-0.14-1.fc13.i686
Installing : avahi-0.6.27-1.fc14.i686

4. Then restart rpcbind service and check # rpcinfo -p status

5. Then restart nfs service.

6. Check the NFS daemon are avaiable in all run levels by #chkconfig nfs –list

7. Now restart the NFS service where the service starts successfully.
