Lotus Notes and SLB
I have lotus notes cluster (lotus application cluster - active/passive
node) with 2 servers as internal mail sistem and 2 mail relay servers
in DMZ running Postfix.
I'm setting up high avalilabilty mail system with server load balancing
switches. I would like to know how to perform healt-cheking from
SLB switch to Lotus Notes. In case that primary (active) Lotus node goes
down, SLB must be aware in reroute mail from DMZ to the second Lotus node.
At the moment I can monitor the tcp 1352 and tcp 25 port on active Lotus
node (i can get the info that the tcp port is alive/open)
I'm also monitoring the banner of the Lotus Notes node on port tcp 25
which tell the SLB switch that smtp service on node1
is really running.

My question is how can I get the same/similar output on tcp 1352 port of
Lotus Notes for healt-cheking.
I already tried to telnet on LN port (telnet
lndnode1.internal-domain.local 1352) but LN didn't gave me back any
