Problem with SSH in NetConfig!

Hello,

if someone could help me I would appreciate a lot.

I have RME 4.3.0 and I have difficulties in configuring NetConfig to use

SSH for changing configurations on devices. SSH is configured correctly

on devices because I can connect from normal SSH client with the same

credentials which NetConfig uses for SSH. It is interesting that with

telnet it works OK, no problem, same credentials. Telnet is not solution,

because I have explicit request that transport protocol must be SSH.

When I run SSH, NetConfig shows output : successuful, not attempted!

I captured some debuging information from devices (cisco router 2911) :

It looks like it tries two times and terminates.

If someone knows solution, please answer me!

Thanks in advance.

Re: Problem with SSH in NetConfig!

There should be a directory created for your Netconfig job which is the same as the job ID (e.g. NMSROOT/files/rme/jobs/NetConfigJob/JID).  Post the contents of this directory.

Re: Problem with SSH in NetConfig!

Hello again, and thanks for your time,

Here you are files from specified directory that I can

post here, because of security concerns. I turned

debugging level for NetConfig, and hope that it will

be usefull.

Thanks again!
