Martin J. Hannigan put this into my mailbox:[ snip ]Two months with these filters, and no complaints yet.Was that some wrappered service? Looked like tcp_wrappers. I think a router with enough memory would be a better performer for filtering activies at that layer.
What I actually did was take sendmail 8.8.5, #define TCPWRAPPERS, and then modify the code so that it calls hosts_ctl (the function that checks /etc/hosts.deny) on connect, not just on MAIL FROM. Yes, this causes remote sites to churn if they get denied, but from the syslogs, there really aren't that many people who try for that long. The exact patch was posted to bugtraq a while back. If you're interested, please mail me privately. -dalvenjah -- Dalvenjah FoxFire (aka Sven Nielsen) "The weapon which causes the most Founder, the DALnet IRC Network damage to the Internet is the keyboard." e-mail: dalvenjah () dal net WWW: http://www.dal.net/~dalvenjah/ whois: SN90 Try DALnet! http://www.dal.net/
