Hi,
i'm running CentOS 6.0 on my server and installed mrtg from the rpm-package mrtg-2.16.2 . I also installed the depending packages perl-IO-Socket-INET6 perl-Socket6 ....
mrtg works fine with IPV4-Addresses. When i specify a Target by IPV6-Address (or hostname resolving to a V6-address) mrtg fails.
Here i have a small sample-config for V4 which is working:
LogDir: /tmp ThreshDir: /tmp HtmlDir: /tmp ImageDir: /tmp LogDir: /tmp EnableIPv6: yes Target[bai-gw-i-oct]: ifInOctets.1&ifOutOctets.1:abc123@85.237.138.221 Title[bai-gw-i-oct]: Test MaxBytes[bai-gw-i-oct]: 100000000 ----------------------------------------------------
Here the same for V6 which fails. When running mrtg there is no snmp-packet sent to the network.

With snmpwalk (net-snmp-utils) i can reach the device via IPV4 and IPV6.
Where is my mistake? Has anyone a hint?
Thanks in advance, 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.
I had to install the perl-Module from source-code "by hand". Is this a dependency, which is not resolved by yum?
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
