Hmmm.... I was wondering if we might want to call ioctl(..., SIOCGIFCONF...) followed by SIOCGIFADDR to get the list of our IP addresses... So we can do some filtering on people claiming to be us.
I.e. if someone connects to me and says "helo 71.36.29.88" then I know for a fact that they aren't me... One other thing I thought about: what about detecting spammers, and then looking up the CIDR block that their address belongs to, and adding it to a blacklist automatically in filter_relay()? We could set a threshold for the number of offenses before they get added in. That way, if the ratware ever gets more sophisticated and figures out how we are detecting them and gets around it... it would be too late, as they would be remembered as spammers. -Philip _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
