[Ntop-dev] PR_TWTATGB - no Historical Protocol View nor NetworkLoad graphs for LAN cards on Windows

[Burton Strauss]

(1) Why 64 ... Is it that it's big enough for your renamed network cards?
Or is that the actual size limit on A network card name?

(2) You were going to send me the updated instructions and diffs, with an
eye to getting this stuff into 3.2, but you are running out of time.  I want
to create rc1 in the next 24 hrs.

Problem solved. Just had to change rrdInterface[32] to rrdInterface[64] in
line 2066 of plugins/rrdplugin.c and recompile. If anyone is interested I
made the mingw-compatible source available at
http://savefile.com/projects.php?pid=420840 - it's up-to-date with CVS and
running rock solid on my Windows XP Pro SP2 notebook for 1h20mins now.
Now I think I'll take a look at arbitrary graphs - ntop CVS still goes down
in flames with those.
Regards,

Georger
