how can i get permission again when i change the virtual controller IP?

Hi,

 

I changed the IP from virtual controller and then when i try to connect ssh, It shows the following 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 a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
75:da:ca:66:7f:5a:7a:09:eb:0e:ab:64:e1:0f:02:dd.
Please contact your system administrator.
Add correct host key in /home/guest/.ssh/known_hosts to get rid of this message.
Offending RSA key in /home/guest/.ssh/known_hosts:3
RSA host key for 192.168.1.100 has changed and you have requested strict checking.
Host key verification failed.

 

What i should do now? Of course if I define the original IP again I can acces, but i think there are another solution.

 

Thanks for all,

You can delete the known_hosts file for all of your known hosts using the command ?rm ?r /home/guest/.ssh/known_hosts?. You will get a message after that each time you attempt to access a new host (even if you had accessed and accepted the key before today).

You need to delete the SSH key entry from the cache in your SSH client.

Re: how can i get permission again when i change the virtual controller IP

in principle there should not be a problem. are you sure there isn't a firewall or issue with routing to the Aruba APs?
