There's no tooling specifically for doing this, but the plugin
supports
it. In order to get it to use a fixed port, you'll need to edit the
directory server entry for "cn=NIS Server, cn=plugins, cn=config" and
add a "nsslapd-pluginarg0" value which contains the port number you'd
like it to use.
You can do this either by stopping the directory server, editing its
dse.ldif file directly, and then restarting it, or by editing the
entry
"live" using ldapmodify and then restarting the server. The latter
method (I'm using port 541 here) looks something like this:
# ldapmodify -x -D "cn=Directory Manager" -W <<- EOF
dn: cn=NIS Server,cn=plugins,cn=config
changetype: modify
replace: nsslapd-pluginarg0
nsslapd-pluginarg0: 541
-
EOF
# ipactl restart
You'll need to supply the Directory Manager password. Once that's
done,
running "rpcinfo -p" on the server should show that the NIS service is
listening on the desired port.

Nalin,
Thanks a lot for the tip. It definitely looks like this put me on the
right path though I am not quite there yet.
Doing what you suggested did not quite work. For one thing, the right
cn is "NIS", not "NIS Server". Another thing is, it does not look like
the LDIF files in question have the nsslapd-pluginarg0 parameter - or
are happy with it being added.
You have to shutdown the directory server first
service dirsrv stop
or
systemctl stop dirsrv.target
Do you happen to have a copy of your LDIF configuration file with the
relevant configuration by any chance? That could come in handy.
Cheers,
Boris.
