Nice ride with a co-worker.  (its Google Map, so you can zoom in on the track via the control)

    The new netsh in Vista is simly updated with a new section for outbound filtering.  I took some time and made a few example rules for those struggling with the syntax.  The rules below are linked here (Vista-Outbound-Firewall-Rules.bat.txt (1.23 KB)).

Pretty nice.  Finding some processes trying to access the internet such as Windows Error Reporting.  More a pain to translate the event log entries generated then anything.


netsh advfirewall firewall add rule name="IE (TCP)" dir=out program="c:\program files\internet explorer\iexplore.exe" protocol=TCP localip=any localport=any remoteip=any remoteport=80,443 action=allow
netsh advfirewall firewall add rule name="IE (UDP)" dir=out program="c:\program files\internet explorer\iexplore.exe" protocol=UDP localip=any localport=any remoteip=any remoteport=80,443 action=allow


netsh advfirewall firewall add rule name="Firefox (TCP)" dir=out program="C:\Program Files\Mozilla Firefox\firefox.exe" protocol=TCP localip=any localport=any remoteip=any remoteport=80,443 action=allow
netsh advfirewall firewall add rule name="Firefox (UDP)" dir=out program="C:\Program Files\Mozilla Firefox\firefox.exe" protocol=UDP localip=any localport=any remoteip=any remoteport=80,443 action=allow


netsh advfirewall firewall add rule name="Windows Messenger (TCP)" dir=out program="c:\program files\msn messenger\msnmsgr.exe" protocol=TCP localip=any localport=any remoteip=any remoteport=80,443,1863 action=allow
netsh advfirewall firewall add rule name="Windows Messenger (UDP)" dir=out program="c:\program files\msn messenger\msnmsgr.exe" protocol=UDP localip=any localport=any remoteip=any remoteport=80,443,1863 action=allow

Yikes, read this post on a Microsoft forum and it has scared me a little bit about Vista's BitLocker feature.

http://windowshelp.microsoft.com/communities/newsgroups/en-us/default.mspx?dg=microsoft.public.windows.vista.security&tid=9550eb1d-edd7-4905-8e8a-fcaa997faa99&lang=en&cr=US&sloc=en-us&p=1

This essentially means that your system "may" have a significant failure because of a single bit error on a drive.  Now I know I'm sounding a little brazen here, but this is a legitimate concern for users, especially corporate users - the ones most likely to implement this feature.

The only workarounds to this problem are:

  1. Don't use BitLocker - Less security is safer?
  2. Perform regular backups of your system - this may help but a typical user won't be capable of restoring their system without administrative intervention.  So you end up taking a user down for a day to get their system restored or rebuilt from image - great, just great.

I guess we'll just have to wait for a RAID-able solution.  or some type of parity option.

I'm posting from inside Windows Vista, the next OS and I must say its pretty sweet.  I've encrypted my main partition using BitLocker and messed around with a featureful firewall.  Too bad the firewall and its associated parts needs some work.  It says that it will notify me when something is blocked, but I never received a single alert for anything.

Here is an updated Dryer Road Park trail guide that has numerous mistakes due to GPS inaccuracy (?), but I wanted to get this posted as there are many more trails.

Enjoy!  Be aware that it can be very slow to load.

Rode here a couple times this week.  Almost 8 miles of technical riding.  Click the pic for the interactive Google map.

Here is the profile of that trail (careful! - its huge so you can see the most detail).  The way we rode this trail it goes in a figure 8, starting at the bottom right and going across to the bottom left, then to the upper right, across to the upper left, then down to the bottom right.

Here is a Google Earth version, with altitude data included so you see a wall indicating the trail altitude.  Clearly not great accuracy, but probably somewhat close.

Other then riding at Dryer Road Park, which rocks, there is another place to ride near Rochester.  Royal Coach Parkland, which is public property as far as I know.
