warning: possible dns spoofing detected!
Im trying to connect to my university's server using SSH on Terminal from home (outside the uni networks). Im getting the following:
My-Computer:~ mycomputer$ ssh username@hostaddress.ac.uk
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: POSSIBLE DNS SPOOFING DETECTED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
The RSA host key hostaddress.ac.uk has changed,
and the key for the according IP address 146.176.restofip.here
is unknown. This could either mean that
DNS SPOOFING is happening or the IP address for the host
and its host key have changed at the same time.
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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
8a:0b:63:5b:43:64restofhexhere3e:78.
Please contact your system administrator.
Add correct host key in /Users/mycomputer/.ssh/known_hosts to get rid of this message.
Offending key in /Users/mycomputer/.ssh/known_hosts:1
RSA host key hostaddress.ac.uk has changed and you have requested strict checking.
Host key verification failed.
My -Computer:~ mycomputer$
Im on a cable connection at home using a linksys wireless router, on OSX 10.4.10.
Quite concerned about the DNS spoofing and man-in-the-middle attack. Is this a problem at my end rather than the universities? From the error message I gather that its something to do with my security settings and me missing a key somewhere...not too sure what this means tho.
I tried speaking with C&IT at my university, but I got the 'no idea about macs sorry cant help'.
Any ideas?
