We have a problem with opening Terminals on HMC 7.3.*
We have the following configuration.
workstation(Windows with Firefox:10.76.12.1) -> (en0:10.76.12.2)CSM server(en1:192.168.133.1) -> (eth0:192.168.133.2) HMC (eth1: 10.0.0.1) -> (SP1:10.0.0.254)
Now we tunnel the HMC(443) through PUTTY with an ssh tunnel,
HMC 443 ->csm -> workstation 443.
We can open up almost everything.
ASM menu is working DLPAR is working, en HMC onfiguration is all working.
But we arent able to open a Terminal Window to a LPAR.
we tried forwarding port 9735(vtty) and 2302(5250 terminal).
but this doest work either.
Did a test and it seems the terminal - which is a java application - connects directly to the HMC, not via the browser:
tcp6 0 0 192.168.0.56:38353 192.168.40.2:9960 ESTABLISHED 18782/java_vm
tcp6 0 0 192.168.0.56:48291 192.168.40.2:443 ESTABLISHED 18782/java_vm
(192.168.40.2 is my HMC, 192.168.0.56 is my laptop)
The connection is either some proprietary protocol or SSL but in the SSL case I think it requires some client certificate as connecting with a generic SSL enabled telnet client does not work:
folkert@debianfvhbps:~$ telnet-ssl -z ssl 192.168.40.2 9960
Trying 192.168.40.2...
Connected to 192.168.40.2.
Escape character is '^]'.
Connection closed by foreign host.
Is there another port we are forgetting or is it not possible to tunnel the console.
Should we place the HMC in de 10.76.12 range aswel to get this working.
This is not what we want because the HMC should not be available directly. on the workstation LAN.
What I did is starting a vnc server on a system in the same lan as the hmc. Then i connected to this vnc-server via a tunnel-over-ssh. It then was just a matter of starting a browser in this vnc session.
