CentOS 5 updated, Xen host. The portmap on this machine is somehow "stuck" and I can't figure out why. I enabled it to be able to mount a remote nfs share. The first hurdle was that "portmap" didn't appear in the chkconfig list, it was installed with the initial packages but not added to chkconfig. Took me a while to figure this out. Adding and starting it up is no problem. But nfs still doesn't work and when I try rpcinfo -p that just hangs until it finally times out after a long while (rpcinfo to another machine is fine). An strace at that time indeed shows that it is stuck trying to connect to port 111 on localhost. Same when I try to connect with telnet. Port 111 shows up on lsof UDP and TCP and there's no error when portmap starts up. There's nothing in iptables or hosts.deny that could prevent a connect. SELinux is permissive. What could block those connects?
