Can not discover system

[Ollie - SC]

Hi there, in connection with previouse thread. Im trying to manage systems over a wan. I can use putty to see (and even connect) to a server but HPSIM can not see it or discover it anymore. Nothing has been changed so whats happened? Please help this is really baffeling me!!!

Not a good idea to refer to a "previouse thread" as they get sorted by when they were last replied to. All info should be in a new thread. Things like OS, version, model etc. can all help.

Check you've not got filters enabled for Unknown or Unmanaged devices - under discovery.

Can you ping the server from the CMS?

What happens if you try and manually discovery the server using IP name from HPSIM?

Thanks for a productive reply!

Firstly the ping fails.
When I manually discover the system it appears in "all systems" as unknown then after about 5 minutes changes back to unreachable.

There are no filters set up, Im trying to keep it as open as I can without threatening the customers security. Port 22 is open and I can connect through using putty.exe

Any ideas?

Sounds like it's being discovered on the SSH Port. While it's discovered you can click on the system name, expand (sorry not at work) one of the sections and it will list the discovered protocols. Unknown means it's found a protocol but not been able to use it to identify the device.

You could try opening up SNMP (161). On the target server side you can restrict SNMP to just accept localhost and the HPSIM Server.

It's almost like the server gets discovered by the discovery protocol and then when the first hardware polling task runs it flags it as unreachable. Not too sure why that would be though.

Thanks for your reply.

I cant see anywere let alone in the log of events where it says it found it and on what port. We need to get this working just over 22 dont really want to open any more ports if we can avoid it.

Can you clarify that everything should work ok over port22 - ssh?
