Logging on to controller using Putty

Hello all,

When I want to log on to the 3600 controller, using SSH and Putty.
The login name is asked immediatly and I have to wait for like 20 seconds before I can fill out my password.

Does anyone have an idead how this comes?
It takes annoyngly long to log on this way.

Thanks for your answers.

Kind regards

Do you have a DNS server configured and ip domain lookup in your configuration?

ip name-server 8.8.8.8
ip domain-lookup

Or do you have radius/tacacs set-up for admin access/authentication?
If so then it might be mis-configured and then eventually timing out and using the local database for admin access.

Look for:
aaa authentication mgmt
and check what/if any authentication is associated to this.

Is this a local controller? If you look down a couple of threads you will see my post about the ipsec tunnels between the master and locals going down. One symptom that I have noticed is that when the ipsec tunnel is down, authentication on the local controllers has about a half minute pause. Can you ping your master ip address from the locals cli (if it is a local that is)?

The local controller does not authenticate management users to the master. It only authenticates locally, or to an external server and that does NOT depend on the ipsec tunnel being up to the master controller.

Re: Logging on to controller using Putty

That all sounds great and I believe you, but I can tell you from actual experience that when my ipsec tunnel goes down (which right now it does so frequently) local authentication via putty takes a long time. It could certainly be something else that is causing both issues for me, but I do authenticate locally and it does take a long time. I don't know why, but it does.

Re: Logging on to controller using Putty

In that case, please open a case. This does not sound like it is simple.

I opened it about a week ago, and we are all still stumped.
