This is version 1.05 of Net::Traceroute. Users upgrading from previous versions, please note that there has been an interface change. Your program may not work. Please see "CLONING SUPPORT BEFORE 1.04" in the pod documentation. Net::Traceroute is available from CPAN and my home page. My CPAN area is authors/id/H/HA/HAG, and my home page is currently http://www.linnaean.org/~hag/ . I hope you find the module useful. Changes from previous version includes bug fixes, traceroute6 support (thanks to Mohacsi Janos <mohacsi@ik.bme.hu>), better subclassing support, and new traceroute options. This traceroute module works by parsing your vendor's traceroute command. As such, some systems may not work; Windows is known not to. Patches to support your favorite OS are welcome.

"\n"; } }
