Cisco 3550 - SSH2

sendalotsendalot Posts: 328Member
I'm struggling to make SSH 2 work on Cisco 3550-PWR router.

It has SSH 1.5/1,9 and complains to generate 768-bit key when I try to activate SSH 2. Even after I generate the keys of 2048, it still complains.

I'm able to SSH in using 1.5/1.9 but not 2 yet.

It's been a while since I've done R&S and could use a little help.

Thanks.

    Question 1: Are you using the command ip ssh version 2 to attempt in activating SSH version 2?
    Question 2: What is the exact image file name you see in show version?
    Question 3: What IOS are you running (Which goes along with question 2)?

    (1) Yes, and it complains to generate rsa keys of size 768, which I already did.

    When it "complains", what error does it give you?

    "please create rsa keys to enable ssh2"

    BUT, I tried again just now and it works. Seems your reply post did wonder to my switch.

    Thank you for that.
