Is there still justification for denying transit for ms-sql slammer ports?probably not, but that's really a local-to-your-asn decision.
I dunno about that. I know it was more than a year ago, but at NANOG Miami, someone brought either SQL slammer or a vulnerable laptop and killed the network for a while. Running tcpdump on my notebook, I noticed fairly constant slammer probes while there. We still block it here, and the last time we accidentally removed that filter, a colo customer was promptly infected. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
