Get an error when I use 'scp'
 

Hey guys, I'm completely confused about this. I'm sure there has to be a security switch or something but what does this mean exactly?

name@comp:~$ sudo scp -r name@192.168.1.2:/home/name/file ~/

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
56:11:c0:21:fd:19:9c:44:ed:75:d2:ba:4c:d2:6f:10.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending key in /root/.ssh/known_hosts:1
RSA host key for 192.168.1.2 has changed and you have requested strict checking.Host key verification failed.

Does this mean on 192.168.1.2 I have to add the ip address of the computer I'm on to /root/.ssh/known_hosts ? I've never dealt with this before. Any answer you guys can give would be great!

delete the relevant line in the known_hosts file and you'll get it automatically added next time.

That'll fix it, but there could be something more serious here.

OP: Did you recently reinstall that machine or make a major upgrade? If not, I'd wonder why it has a new host key.

Well I haven't had a chance to try again after deleting the line in known_hosts file but yes, it's a fresh install of Ubuntu 6.06. I did some scp'n before the install which I guess would give it to think it's a different key.

I'll try it as soon as I get home today from work. Thanks for the replies!
