Hello List,

is there a option, to bind mrtg (i'm using Version 2.16) to a specific

In the mailing list
and in the user-manual i found the following IPV4-Syntax:

somehost:!                      use as source

When i use this with IPV6 i get an error:

somehost:![ip:v6::address]         doesn't work.

cfg-file:  Target[bai-gw-i-oct]:
ifInOctets.1&ifOutOctets.1:abc123 at bai-gw-i.asdf.de:![2001:a50:933f::f6]
 env LANG=C /usr/bin/mrtg bai.cfg

-> The hostname bai-gw-i.asdf.de resolves to a IPV6 and to a IPV4 address.

Thank you for hints.
