Solaris zones

Hi,

I created a zone with separate /usr for the zone.

when I do ping to newly created zone it showing alive, I am able to login through zone console zlogin -C -E <zone name>

I created a test account on zone which is already existing under global zone and try to ssh, it is working fine but my problem is with root user, when i am doing ssh root@<zonename> it is showing below error

bash-3.00# ssh root@<zonename>

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
ba:b4:d0:44:11:36:f2:fd:31:05:1a:49:6e:3f:7d:43.
Please contact your system administrator.
Add correct host key in /.ssh/known_hosts to get rid of this message.
Offending key in /.ssh/known_hosts:7

RSA host key for <zonename> has changed and you have requested strict checking.
Host key verification failed.

Could some one please help in fixing this issue.

Thanks,

edit the mentioned file "/.ssh/known_hosts" and delete the line with the hostname/ip to your zone and try again...
