Cannot enter the SOEST server

[Esteban82]

I try to enter the server with ssh esteban82@gmtserver.SOEST.Hawaii.edu (as I used to do) and I got this message: Would anyone know what is going on and what should be done? Who is the system administrator?

Have you tried run this command?

ssh-keygen -f "/home/federico/.ssh/known_hosts" -R "gmtserver.soest.hawaii.edu"

Federico, I had that too some time ago. What I did was to follow the instruction. If I had to do something after, that I don't remember.

They’ve changed the ssh keys on the server. It’s probably OK, but worst case it’s a man in the middle attack.

Just update your known_hosts with the command seisman wrote.

Thanks. I will follow your suggestions.

I have now managed to log in. Sorry for the question. I don't have much experience with these things.
