Error : Cannot register service: RPC: Unable to receive; errno = Connection refused

Written by Santosh Prasad

If you are getting the below error while starting your NFS service, this tutorial will help you to fix the this error :


Cannot register service: RPC: Unable to receive; errno = Connection refused unable to register (NFS3_PROGRAM, NFS_V3, udp)

In this article I will show you how to fix the above error.

You will get this error if there is not rpcbind service not installed or not started on your server.

Check rpcbind is running or not if not running you will get below error:

# rpcinfo
rpcinfo: can't contact rpcbind: RPC: Remote system error - No such file or directory

Start rpcbind service on your sever and if not running.

# /etc/init.d/rpcbind start

After starting rpcbind check again.

# rpcinfo

You will get some output like below if running.
