Vendors worried Vista IPv6 too slippery for managed networks

Paul

Researchers have raised new questions about the security of Vista’s IPv6 implementation. James Hoagland from Symantec and Suresh Krishnan from Ericsson wrote an Internet-Draft that calls attention to the Teredo protocol and the fact that many firewalls don’t understand this protocol, and therefore can’t inspect the packets embedded within it.

Teredo is Vista’s last resort to connect to the IPv6 Internet. First, Vista looks for an IPv6 router on the local LAN. If so, the router will provide the Vista machine with IPv6 addresses and “native” (not tunneled) connectivity. If there is no IPv6 router, but the Vista machine has a public IPv4 address (i.e., not one from the 10-net or any of the other private address ranges from RFC 1918), it uses the 6to4 tunneling mechanism that embeds IPv6 packets in IPv4 packets. However, 6to4 can’t create IPv6 addresses from a private IPv4 address. Teredo, the third mechanism, is able to do this, so if you’re behind a network address translator (NAT) then Vista uses Teredo.

Browse the Internet Anonymously with Tor

Paul

Video weblog Unwired explains how to browse the internet anonymously with The Onion Router network (commonly known as Tor). We’ve covered anonymous browsing with Tor in the past, but this Unwired explanation features a nice introduction to how Tor works and how to get started with Tor using the TorButton Firefox extension. Concerned about privacy at work? Check out more ways to bolster your browsing privacy on the job.

Tag Your Tunes by Mood with Moody

Paul

moody.pngWindows/Mac only: Tag your iTunes music by mood with the freeware, color-based tagging utility Moody. While your music is playing, just pick a color for the song with Moody’s 16-color scale (sad to happy, calm to intense). Once tagged, Moody writes the mood to the comments of your song’s metadata (it’ll look something like MoodyC3). You can either use that metadata to create mood-based smart playlists or just use Moody to fire up a playlist based on your mood. It may sound a bit tedious, but if you put Moody in quick tag mode, you can tag a lot of music pretty quickly. Moody is freeware, Windows (with .NET) and Mac OS X only.

This one looks good to use if you are in a certain mood!! It has it own idea going for it. I might try it out myself!!

Add System Monitoring to Your Desktop with CoolMon

Paul

coolmon.pngWindows only: Freeware application CoolMon monitors your systems vitals with attractive desktop-embedded widgets. In very basic operation, CoolMon displays information like RAM usage, hard drive space, and CPU load, but with the right plugins you can embed just about anything on your desktop—like new email alerts, weather, the song you’re currently listening to, and so on. If all you’re looking for is more of a plain-text to-do list on your desktop, check out previously mentioned Samurize. Mac users should take a look at GeekTool. Setup for CoolMon is a little quirky, so check out Simplehelp’s post guide if you’re having trouble. CoolMon is freeware, Windows only.
