I needed to talk to traceroute within some perl scripts, and actually use the information within the traceroute. Nothing hard, nothing wierd, just traceroute. If you don't know what traceroute is, you probably don't care about this module. I have released version 1.01 of Net::Traceroute to 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. 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"; } }
