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.
LogDir: /tmp
ThreshDir: /tmp
HtmlDir: /tmp
ImageDir: /tmp
LogDir: /tmp

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
