[mpich-discuss] start MPD daemons on 2 different subnets

[Na Zhang]

Dear developers,

We want to start MPD daemons on 2 different subnets: for example,
subnet #1 192.168.0.0/24 and subnet #2: 192.168.1.0/24

The two subnets are connected via switches and they can talk to each
other. Next, we'd start MPD daemons on two nodes:

Node #1 (in subnet #1): (hostname:node_001) IP=192.168.0.1
Node #2 (in subnet #2): (hostname:node_002) IP=192.168.1.1

We used the following commands:

on Node #1: mpd --ifhn=192.168.0.1 --daemon
(daemon is successfully started on node_001)

on Node #2: mpd -h node_001 -p <node1's_port_number>
--ifhn=192.168.1.1  --daemon
(daemon cannot be started on Node #2. there is no error message, we
use "mpdtrace" to check on Node #1, it shows no daemon started on Node
#2 )

Node #2 cannot join the ring that is generated by node #1.

How should we do?

Thank you in advance.

Sincerely,
Na Zhang
