[lustre-discuss] No port 988?

Hi,

I've built and installed lustre on two VirtualBoxes running Rocky 8.8 
and formatted one as the MGS/MDS and the other as OSS, following a 
presentation from Oak Ridge National Laboratory: "Creating a Lustre Test 
System from Source with Virtual Machines" (sorry, no link; it was a 
while ago I downloaded them).

I can mount the filesystems on the MDS, but when I try from the OSS, it 
just times out - from dmesg:

[root at oss1 log]# dmesg | grep -i lustre
[  564.028680] Lustre: Lustre: Build Version: 2.15.58_42_ga54a206
[  625.567672] LustreError: 15f-b: lustre-OST0000: cannot register this 
server with the MGS: rc = -110. Is the MGS running?
[  625.567767] LustreError:

[  625.567851] LustreError: 1789:0:(tgt_mount.c:1752:server_put_super())

[  625.567894] LustreError:

[  625.588251] LustreError: 
1789:0:(tgt_mount.c:2365:lustre_tgt_fill_super()) Unable to mount  (-110)

Both 'nmap' and 'netstat -nap' show that there is nothing listening on 
port 988:

[root at mds ~]# netstat -nap | grep -i listen
tcp        0      0 0.0.0.0:111             0.0.0.0:*

tcp        0      0 0.0.0.0:22              0.0.0.0:*

tcp6       0      0 :::111                  :::*

tcp6       0      0 :::22                   :::* 
LISTEN      806/sshd

What should be listening on 988?
