What's so bad about pre-emptive open-relay scanning is that if you feel that is justified, you pretty much have accepted that anybody who pleases may scan anybody else's network for any weakness he or she would like to probe for.
Whether you like / agree with it or not, this is happening and you can't stop it. Even back in the very early 90's you pretty much couldn't put a system on an internet connected network without people probing it, attempting to log into it, etc. There's a big difference between open-relay testing and port scanning / vulnerability probing. Saying that the former will lead to more of the latter is silly with current levels of the latter we already have. I've seen new systems hacked within 24h of being put on the net on a previously unused IP. Any argument that open-relay scanning will lead to more vulnerability scanning is just silly. -- ---------------------------------------------------------------------- Jon Lewis *jlewis () lewis org*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
