Just updated the release of SIPVicious to 0.2.4 to include a couple of bug fixes in svwar and a new feature. The new "--template" parameter allows you to make use of format strings to create more flexible ranges. Some examples include scanning prefixes or suffixes.. which apparently can be quite useful with certain environments ;-)
Many thanks to Teodor Georgiev for his patience and help in making SIPVicious more robust and reliable!
Here's a link to the full Changelog.
Grab the tarball or the zip file.
To upgrade to the svn version simply run "svn update" as usual - enjoy
