Hi all,
I want to map an NFS share from a remote server to a local CentOS 5.4 server, but have a problem with portmap:
root@mercury:[~]$ service portmap restart pmap_getmaps rpc problem: RPC: Unable to receive; errno = Connection reset by peer Stopping portmap: [FAILED] Starting portmap: [ OK ] root@mercury:[~]$ service portmap status portmap dead but subsys locked root@mercury:[~]$
What is "subsys", and how do I "unlock it"?
/var/log/messages gives me this:
Feb 3 13:44:23 mercury portmap[2221]: cannot bind udp: Address already in use
Which address is it referring to? Portmap isn't running so I don't see how it can be in use. Or should I be looking for the problem elsewhere?
Google search results sugested opening port 111 in the firewall, which I have, but still get the error. And I cannot, at any costs, reboot this server. So, is there a way to fix this?

The first thing I would do is to see if there is something running on the portmap port:
# netstat -ap --inet
Check for sunrpc (which is the service name associated with the portmapper, as listed in /etc/services).

Thanx Geoff :)
Should it be running, or not?
root@mercury:[~]$ netstat -ap --inet | grep rpc tcp 0 0 *:sunrpc *:* LISTEN 6458/portsentry udp 0 0 localhost:filenet-rpc localhost:filenet-rpc ESTABLISHED 1980/postmaster

root@mercury:[~]$ netstat -ap --inet | grep rpc
tcp 0 0 *:sunrpc *:*
LISTEN 6458/portsentry
udp 0 0 localhost:filenet-rpc localhost:filenet-rpc
ESTABLISHED 1980/postmaster
It looks like you need to deconfigure portsentry from listening on that port and then you should be good to go. IOW, portsentry is ok to run, but not on your portmapper port when you need to run portmapper.

Check if there is lock file for portmap under /var/run and remove it and try again.
Use also netstat -lp --ip to check if portmap is already running.
