Mac SSH Problem.....

I get this error when trying to SSH to a server

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@@
@ WARNING: POSSIBLE DNS SPOOFING DETECTED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @@@@@@@@@
The RSA host key for myhost.com has changed,
and the key for the according IP address 10.25.19.7
is unchanged. 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.

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
fe:ad:4f:a0:36:59:03:34:2e:66:1e:2a:be:93:08:34.
Please contact your system administrator.
Add correct host key in /Users/halo/.ssh/known_hosts to get rid of this message.
Offending key in /Users/halo/.ssh/known_hosts:1
RSA host key for myhost.com has changed and you have requested strict checking.
Host key verification failed.

How do I disable strict checking or remove this error?

You can simply delete /User/halo/.ssh/known_hosts file or remove the SSH key from that file. Has your server or IP changed? This could be a spoof.

This seems like a work-around (and it does work) but how do I disable strict-checking?
