However, today https://lists.freebsd.org/pipermail/freebsd-questions/2005-January/073751.html I tried to start it again and I am getting this error: Cannot register service: RPC: Authentication error; why = Client credential too weak unable to register (X_PROG, X_VERS, udp) Can anybody tell me what the cause of this error can be? rpcinfo gives me this: program version netid address service owner 100000 4 tcp6 ::.0.111 portmapper superuser 100000 3 tcp6 ::.0.111 portmapper superuser 100000 4 udp6 ::.0.111 portmapper superuser 100000 3 udp6 ::.0.111 portmapper superuser 100000 http://stackoverflow.com/questions/13111910/rpc-authentication-error 4 tcp 0.0.0.0.0.111 portmapper superuser 100000 3 tcp 0.0.0.0.0.111 portmapper superuser 100000 2 tcp 0.0.0.0.0.111 portmapper superuser 100000 4 udp 0.0.0.0.0.111 portmapper superuser 100000 3 udp 0.0.0.0.0.111 portmapper superuser 100000 2 udp 0.0.0.0.0.111 portmapper superuser 100000 4 local /run/rpcbind.sock portmapper superuser 100000 3 local /run/rpcbind.sock portmapper superuser The weird thing is that I haven't even been using this pc the past week. Are there any services that should be running? Hope you can help me out.

(From the manual: "Normally rpcbind accepts these requests only from the loopback interface for security reasons. This change is necessary for programs that were compiled with earlier versions of the rpc library and do not make those requests using the loopback interface.") –eregon Oct 23 '13 at 13:12

From looking at your prompt # I http://unix.derkeiler.com/Mailing-Lists/FreeBSD/questions/2012-07/msg00130.html think you are, but I ask just to make sure. You can also take a look at http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network- nfs.html in the handbook Thanks for the reply. Yes, http://kb.kristianreese.com/index.php?View=entry&EntryID=25 I'm running as root on the client when I try the mount. It was the handbook I was following in my attempt to set up NFS. OK. With authentication error -n (allow from non root users) for mountd the mount succeeds although without it doesn't but you are root on the client. The nfs server is use is still 7.4 and I cannot find a difference in the man pages of 7 and 9 mountd and mount_nfs regarding to this issue. In regard to the security why = client implications, I think that we don't want mounts from trusted clients by a non root user who cannot bind to privileged ports, thus deny unprivileged ports.
