ssh in ivm

Jorge Pons — Fri, 22 Oct 2010 09:36:18 GMT

Hi

the question is about "timeout" when I connect to a IVM guest. I said "timeout" because I loose the screen, when I do, for example "ll". After this, I type touch "hola", and this file is created, but I cant see anything in this session.

If I connect with Telnet, I haven´t any problem

The HW is Blade 860c i2 into C7000 chassis with Virtual Connect. I have also VLANs that are created in vswitch.

Host: 11.31, Guest 11.23. IVM 4.2

Thnaks in advance, Jorge

Hi ani007

Thanks for your rapid response.
I donÂ´t think this could be the problem because is not at x seconds, it only loose the screen with some commands.

Thanks

Hi Ani

dont worry for delay.
I restart sshd daemon and the result is the same, the "screen lost".

Hi Ani

It doesnt work. I think the problem is the echo of connection.

On the server, login as root and edit /etc/ssh/sshd_config and add the line:

ClientAliveInterval 60

Donâ t forget to restart sshd on the server after you save the file. don't forget to tk the bckup before editing the file.

Hi Ani

I dont think the problem is time alive, I think the problem is when, for example, I start sam, the screen not update and I cant see anything. Also in /etc I type "ll" and lost local echo, and I dont see anything, but after this I do "touch hola" and hola file is created.
