Description Orion Poplawski 2015-12-10 18:12:13 EST
Description of problem:

As it currently stands, rpcbind is only activated by connection via /var/run/rpcbind.sock, but not by attempts to connect to the sunrpc UDP or TCP port.  So svc_register(..., IPROTO_TCP) fails with:

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

Version-Release number of selected component (if applicable):

Now, we probably don't want to have a network facing socket enabled by default, but we could have a separate disabled by default socket:


Description=RPCbind Server Network Activation Socket



Interestingly enough, once rpcbind is started by the local /var/run/rpcbind.sock it listens on the UDP and TCP ports anyway.   But I suppose that is always necessary?
Comment 1 Orion Poplawski 2015-12-10 18:45:20 EST
Except for the fact that just doesn't work.  Perhaps what is just needed is to be able to enable and start rpcbind.service directly by having:


in rpcbind.service.
Comment 2 Orion Poplawski 2015-12-11 15:20:26 EST
Well, that would be:


to keep the socket activation as well.  Workaround is just to do:

ln -s /usr/lib/systemd/system/rpcbind.service /etc/systemd/system/sockets.target.wants/rpcbind.service

manually instead of systemctl enable rpcbind.service.
Comment 3 Orion Poplawski 2015-12-17 12:40:48 EST
Sorry, that workaround should be:

ln -s /usr/lib/systemd/system/rpcbind.service /etc/systemd/system/multi-user.target.wants/rpcbind.service
