Chandler Bing?  Guess since "Friends" you haven't had much work huh?

Can't speak about the map - haven't used that feature yet - bells and
whistles to me.

As for netflow, I have two netflow devices operating just fine.  I'm
using a different UDP port for each one.  Not sure if that's the proper
way to do it or not, but seems to be working.  As for an upper limit -
not sure.  There are some upper limits in the code - for instance the
"Host Clusters" is coded at 16 max; so there MAY be some max number of
netflow devices in the code somewhere.

Why might you need so many netflow instances?  Typically you collect
data at aggregation area's in the net.  I have a fairly large LAN/WAN
and although the two I have now is not quite enough, I can't imagine
needing more than 4 or 5 max.

Subject: [Ntop] NTOP new install, Local Network Traffic Map error and
too many Netflow devices cause NTOP to stop updating
Importance: High

I just installed NTOP and I'm seeing a couple of anomalies.

First, when I try to display the Local Network Traffic Graph,  I get an
error (see below).  I ensured that graphviz is installed and when I run
the
command listed below from the command line as root, I get the same
error.

                         Local Network Traffic Map
ERROR


                      Creation of network map failed


Command was:


/usr/bin/dot -Tpng -Goverlap=false /var/ntop/ntop.dot -o
/var/ntop/network_map.png 2>&1


Results were:


Error: Layout was not done.  Missing layout plugins?


Second, when I add Netflow devices, the first works, but after I add
more
than 10 it stops updating.  The devices are not setup for netflow yet as
I'm waiting for AT&T to make the changes, but removing all of them
except
for the one device that is setup to send netflow has restored
functionality.  Is there any kind of limitation on how many devices you
can
receive netflow from or was it that they were not setup yet and that
cause
a problem?

Thanks
