[Nfsen-discuss] no graphs in the PortTracker plugin

[Chelo M. <che...@re...>]

Hello,
I have checked the mailing list trying to find tha solution to the
problem I have and I saw a thread about it but without saying how to
solve it (thread "porttracker not producing graphs"). In my case I'm
using Red Hat Enterprise 4, nfsen 1.2.4, nfdump  1.5-1 and 
PortTracker-v.e-1.5.
I can not get PortTracker to produce graphs. The rrd files are generated
and properly updated as well as the "ports" and "portstatxx" files. The
plugin tab displays info in the botton table, but no GIFs are shown.
I have checked permissions and the configiration of the pugin (and also
reinstalled the plugin) and everything seems to be fine.
The only error I get is in the  error_log (the same error people in the
list commented before):

I was testing the pluing in other machine (Fedora Core 4) and the same
versions of nfsen/nfdump/PortTracker without problems.

Thank in advance,
Chelo
