Issue SSH

[pesanchez2002]

I did upgrade to version of IOS cat4000-i9k91s-mz.122-18.EW2.bin to cat4500-entservicesk9-mz.122-52.SG.bin at a catalyst 4507r engine IV.

Before i could to execute:

ssh 1.1.1.1, without problem.

But after upgrade i can't do that.

In catalyst 4507r:

-----------------

router_4507r#sh ip ssh

SSH Enabled - version 1.99

Authentication timeout: 120 secs; Authentication retries: 3

router_4507r#ssh 1.1.1.1

[Connection to 1.1.1.1 aborted: error status 0]

In router remote:

----------------

Router_remote#sh ip ssh

SSH Enabled - version 1.99

Authentication timeout: 120 secs; Authentication retries: 3

Your issue more than likely is ssh strict host key checking is enabled.

Check your ssh configuration for this command:

ip ssh stricthostkeycheck

If it's in your configuration, you have two options:

1. enable the ip ssh pubkey-chain command: 

ip ssh pubkey-chain

2. Disable strict host key checking

no ip ssh stricthostkeycheck

In your case, I would try option 2.

Good Luck!
