Hello All!
I'm trying to configure NFS on my OL9.5 server machine so that I can log-in and edit
server SQL scripts, set-up, config files etc…
However, I'm getting the following when I try to log in to NFS:
mount.nfs: Connection timed out for…
I've tried installing NFS as per Oracle docs which seemed too basic and I also tried other
Oracle sites but they started to refer to /etc files that don't exist!
I was under the impression that I only needed to open services for:
111 rpc-bind, 2049 nfs, 20048 mountd…
but it now seems that several other ports need to be opened as static as well for firewall purposes.
I checked with nmap from my dev machine and the open ports are getting through the firewalls:
PORT STATE SERVICE
111/tcp open rpcbind
2049/tcp open nfs
9090/tcp open zeus-admin
20048/tcp open mountd
I believe I'm having issues with these additional ports for: nlockmgr and status. Output from rpcinfo…

100021 1 tcp 44795 nlockmgr
100021 3 tcp 44795 nlockmgr
100021 4 tcp 44795 nlockmgr
I've looked at the /etc/nfs.conf file and it looks like I should be able to define the additional ports in this file.
Guidance how to set the correct static port number would be appreciated. Thanks.
