Re: Upgrading from Etch to Lenny ends in SSH problems



Ok, so apparently the problem had all sorts of things to do with the host key being blacklisted, and therefore labeled as 'compromised'. Of course one can't SSH in anymore in such a situation.

How to prevent it? Well, I probably should have checked with ssh-vulnkey before doing the upgrade.

Hi All,

I've just been attempting an (more than just slightly) overdue upgrade from Etch to Lenny on a machine I don't have physical access to. At first, everything seemed to work fine. But after a while my connection (over ssh) was dropped and all my box returns now is 'connection closed' when I try to reconnect. It gives me this:

Of course I've already activated customer support, hoping that my hosting company is willing to physically go to the server. But I was hoping that you might have some suggestions on what I might be able to try. Though I know my options are limited :(

And at the same time I'm wondering what's causing it, and how I could have prevented it. I upgraded with a simple: apt-get dist-upgrade

Thanks!
Wouter
