Octopod - secure file sharing made easy

  View Printable Version 
SecurityOctopod is a system that lets you share files securely with a private group of other users anywhere on the Internet. With Octopod, users can have 'share' directories that Octopod automatically synchronizes with other share members. Octopod is decentralized in that no one user or server is responsible for holding a share's data (instead, all users store data locally), is secure in that only members of a share can access the contents of the share or its member list. Hmm, I hope it will be available soon.

Putting the Spamhaus DROP list in FreeBSD’s ipfw

  View Printable Version 
Security

Are you aware of the Spamhaus DROP list? According to the ladies and gentlemen of Spamhaus:

DROP (Don’t Route Or Peer) is an advisory “drop all traffic” list, consisting of stolen ‘zombie’ netblocks and netblocks controlled entirely by professional spammers. DROP is a tiny sub-set of the SBL designed for use by firewalls and routing equipment.

I've written a shell script which automatically generates FreeBSD ipfw rules from the DROP list. Useful if you run internet facing FreeBSD servers and don't want any traffic from some of the baddest of the bad guys.
