Release highlights

Several bug fixes, tweaks, and a couple of new exciting features.

New Features

Payload search

You can now specify a text or binary pattern or even upload a file and search for matches.  Trisul will reassemble and check all TCP streams in both directions for a match.  It will present all TCP flows that match – you can then pull the packets into Wireshark or Unsniff for further analysis.

Daily usage calendar

You can now display daily totals for any meters for any item on a calendar.  For example you can show on a monthly calendar

  • Total Bytes / In
  • Total Bytes / Out
  • Total Connection
  • Total Alerts

for a  Host like


  1. Resource extraction code has been enhanced. Trisul will log all URLs requested including parameters as before but will do it 2x faster.
  2. Admin can now reset passwords of other users
  3. Web interface will always use the correct packaged version of Ruby.
  4. Minor bugs
  5. Tweaks including verbiage on many pages
  6. Enhancements to Trisul Remote Protocol

Also,  check out our screencasts page at Screenr .  These screencasts are also on Youtube at a lower quality.

We also have a demo server up at – please leave a message in the forum if you would like to check it out.  We will send you a username and password.  It is hosted on a small linode and wont be able to take more than a handful of users at once.
