i don't care about keys

well.  i do and sometimes i don't.  let's just suspend all those, do you want to accept rsa key prompts, shall we?

[systemwide]
in /etc/ssh/ssh_config (global client conf file) add stanza:

Host 192.168.168.*
   StrictHostKeyChecking no
   UserKnownHostsFile=/dev/null

* This may be done by subnet or host.

&

[per session]
$ ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no \
uid@192.168.168.192
