You already had several answers, but this is one that I'd like to
share regardless:
#
# Connect to ssh without recording host-key
#
sshtmp ()
{
ssh -o "StrictHostKeyChecking no" -o "UserKnownHostsFile /dev/null" "$@"
}
I have that in ~/.bash_profile and it lets me run:
sshtmp user@1.2.3.4
The key is ignored, obviously not a thing to do casually, but there
are times when it is useful.
