greetings.

ik have installed on my openBSD MRTG for counting the trafic on my lan.
however, i only gets below messages.

sysName on public@192.168.0.236::::::v4only
at /usr/local/bin/mrtg line 1921

ERROR: Target[192.168.0.236][_OUT_] ' $target->[5]{$mode} ' did not eval into defined data


Can some one give me a clue for what i am doing wrong ?
