Hi,

I have installed Debian 5-64 bit on a virtual machine. On top of that NAV 3.7.0 is installed , also NFSEN 1.3-5 and NFDUMP 1.6.1p1
Everything work as expected , but not graphs is generated through Cricket 1.0.5-9

The logs show errors from NfSenRRD.pm : Unable to create graph, no such file or directory. The graph windows in Nav is displayed , but no data is available visually.
After googling a lot of users see the same problems as I have experienced. They all have downgraded lots of libraries in Perl and Cricket.

Anyone done this setup with success on Debian 5. Solution is highly appreciated

You mention problems with Cricket, but you go on to cite an error message
from NFSen. I'm not quite sure where you're getting with this.

As far as RRD/Cricket is concerned, I believe there are some problems related
to 64-bit platforms. The RRD file format is platform dependent; IIRC,
Cricket tries to sniff an RRD file's header using its own Perl code, rather
than rely on the rrdtool library. Unfortunately, Cricket doesn't recognize
RRD file headers from all platforms, and I think 64-bit is one of them.

AFAIK, you need to patch Cricket to solve this problem. Likely, the patch
you need is this:
http://launchpadlibrarian.net/4703704/Format.pm.x86_64-linux.patch

I don't know that this problem affects Cricket's ability to generate graphs,
though, since it uses rrdtool for that.
