We have caused quite some steer with our review of PeerBlock, a software program that would use blacklists to block IP addresses from communicating with the computer systems that were using the program. PeerBlock was basically a fork of PeerGuardian 2 offering a similar functionality and an active team of developers that would maintain, optimize and increase the functionality of the product.

An interrim beta version of PeerBlock was released today with several important enhancements that should all make it into the PeerBlock 1.0 final release that is expected to be released in the next week. Probably the most important addition in this beta release is a signed driver which helps 64-bit users of Windows Vista and Windows 7 who usually had some problems getting PeerBlock to work on their computer systems thanks to an unsigned driver. There is also no UAC warning prompt when trying to install PeerBlock on these systems anymore.

Mark, the main developer, has posted a huge list of additional improvements in a blog post announcing the beta release of PeerBlock. This includes better usability, warnings if Peer Guardian is running, auto update functionality, archiving improvements and copying over PeerGuardian 2 lists if available.

Check out the full blog post for all changes and known issues. Portable versions and installers are provided at the end of the blog post as well. Users who do not want to test the beta version are advised to wait until the final release is being made available on the website of the project.

Update: Note that PeerBlock has not been updated in over two years. An update was posted last year that mentioned that a new version was in the making, but nothing has been heard of it ever since.

      Feature I’d *kill* for: the ability to, by checking a box, shut off all IPv6 connections. This should work without forcing a restart of any software (let alone the system).

      The #1 headache in initially-seeding a new torrent is IPv6 leeching (in which a leecher’s torrent software attempts to download simultaneously through a regular IPv4 connection and a secondary IPv6 connection — this screws with “initial-seeding” or “super-seeding” algorithms as the IPv6/4 leech pair report instantaneous re-trade and receipt to each other, fooling the uploading software into continuing to reward them even when they’re not trading with anyone else.

      — I say it’s the #1 headache for torrent uploaders because the biggest torrent engines (*cough* uTorrent) has zero interest in solving the problem at their end, meaning uploaders beset by IPc6/w leech pairs can lose up to 25% of their bandwidth.
