[mrtg] mrtg 2.16 ipv6 on centos

[Florian]

Hi,

i solved my first problem and created a new one :-(

After installing the perl-module
IO-Socket-INET6-2.67.tar
the mrtg 2.16 works with V4 and V6-Addresses.

>From mrtg 2.17 i get a new error:

env LANG=C /usr/local/mrtg2172/bin/mrtg bai.cfg
Undefined subroutine &main::AF_UNSPEC called at
/usr/local/mrtg2172/bin/mrtg line 2247.

I get the error in both cases : using IPV4 or IPV6.

Bye, Florian
