It seems like this piece of code is trying to work with IPV6 addresses, which I choppedout of the kernel. Could this be a possibility? - -- Jaco van Tonder Software Developer Direct: +27 11 312 2122 :: Fax: +27 11 312 2122 :: Mobile: +27 83 417 5424 Email: [EMAIL PROTECTED] :: Web: http://www.coocoo.za.net/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (MingW32) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org
