Yes, there are a few postings out there about getting ipv6 routing running with XEN. But I’ll throw this online anyway since there are a few changes I had to make for it to work on my server. This text is intended for people who know their way around Linux and XEN so it will [...]

Checking a list of IPs against RBL
This is more a reminder to myself than anything else … this is small snippet that takes a list of IPs and does a whois on all that aren’t in a RBL
