I want make sure a CentOS7 machine can only be an NFS client and not an NFS server, if possible.
When I type
mount I see-
nfsd on /proc/fs/nfsd type nfsd (rw,relatime)
showmount -e reveals:
clnt_create: RPC: Port mapper failure - Unable to receive: errno 111 (Connection refused)
…so, I'm not sure if an NFS server is running or not.
chkconfig --list and
systemctl list-unit-files | grep enabled also don't indicate an NFS server is running.
