Re: man in the middle attack ?
To me, If ou are teaching a linux class (assumed since you are self proclaiming to be a doctor) the I question why you, as a teacher, are not capable of knowing this or how to troubleshoot.
If on the otherhand you are just teaching something on a linux box, then perhaps calling the IT team at the school should be in order.
Again, just asking what seems to be the obvious first.

Dear linuxers,
Today I registered a lot of students in the class, and 4 hours later I
was in home and got a message one of them could not log in.
So I tried and got this message:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
66:09:66:e3:e1:54:dc:65:e4:a4:74:99:c4:df:3e:ff.
Please contact your system administrator.
Add correct host key in /home/beco/.ssh/known_hosts to get rid of this message.
Offending key in /home/beco/.ssh/known_hosts:1
RSA host key for beco.poli.br has changed and you have requested
strict checking.
Host key verification failed.
What should I do, or where should I look, to understand this problem?
Can I log in with my account remotely to see the problem, or should I
better log in locally?
Thanks,
Beco.
