Solaris

Hi,
In my Linux machine when am trying to do sftp to other server its not getting connected and its showing the below connection error. Even though I checked the daemon which is running fine. Any idea on this error will be helpful.


sftp sftpuser@112.80.93.94
Connecting to 112.80.93.94...

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 DSA host key has just been changed.
The fingerprint for the DSA key sent by the remote host is
8e:27:e8:e0:67:7b:a3:2f:29:30:d4:17:00:eb:6c:03.
Please contact your system administrator.
DSA host key for 112.80.93.94 has changed and you have requested strict checking.
Host key verification failed.

This is a problem with the your known_hosts file. This is a text file in your personal .ssh directory. You have remove the line in that file that matches the host you are trying to connect to. The file is made of lines of keys that match the remote hosts. Each entry starts either with 'someplace.com' (a DNS name) or 122.15.10.192 (an IP).

Then try an sftp connection again, answer 'yes' to the question that will be asked about do you know the identity of the remote host.

This is caused by any change in routing to the remote side, like the addition of new intervening hardware or a new firewall. Or a change on the remote box itself.
