I want to set up a filesharing server with NFS. But when I want to show the conetnts of export I get this:

manuel@server ~ $ showmount
clnt_create: RPC: Port mapper failure - Unable to receive: errno 111 (Connection refused)

What is wrong with it?

Horribly. I read about 5 Tutorials, but none of them mentioned that the service rpcbind is needed.

For Debian

sudo service rpcbind start

does the trick.

    That does not solve the issue for me. If someone has any other suggestion, they are most welcomed! May 31, 2014 at 22:34
  • Is this command run on the NFS server or NFS client. You need to be explicit.

  • @Jim install/start this service on the NFS client

Do the following:

vi /etc/sysconfig/iptables
  1. Remove the reject entry
  2. Remove the forward entry
  3. Save

From the command-line, type:

 iptables -I INPUT -p tcp --dport 111 -j ACCEPT
 iptables -I INPUT -p tcp --dport 2049 -j ACCEPT
 /etc/init.d/iptables save

Restart the rpcbind service.

Run showmount -e ipaddress where "ipaddress" is the IP of your NFS server.

  • I have a server with three different interfaces. Only one of which is allowed the rpcbind action. showmount -e yielded the same error as shown by the original poster. A slight modification, based upon the above, results in a command returning expected results: showmount -e This forces to the local host, rather than one of the other interfaces.

  • Do you change the iptables on the nfs server or client?

I know this is old but I hope this will help other people. This is for Red Hat.

showmount -e server_address
clnt_create: RPC: Port mapper failure - Unable to receive: errno 111 (Connection refused)

Doing this produced a new error.

/sbin/service rpcbind start
showmount -e server_address
clnt_create: RPC: Port mapper failure - Authentication error

This was the fix that got everything to work.

/sbin/service autofs restart
