It's in the source: /* * This is the theoretical upper limit on "NIC"s. This must be large enough to include * the dummy device, other pseudo- devices (sFlow, netFlow) and all of the real and * virtual network interface cards on the -i parameter. * * Note that because the big allocators are dynamic, reducing this will not save * much memory. Still, 32 is absurd for MOST people. * * But, remember - when sniffing from a multihomed interface it is necessary to add * all the virtual interfaces because ntop has to know all the local addresses. * * This affects static allocations: * in graph.c - for reporting * in hash.c - for lastPurgeTime[] in purgeIdleHosts() * in plugin.c - for the flow filters structure * * This affects dynamic allocations in initialize.c - if it's too small for the -i parameter, * there is a warning message in initDevices(). * */ #define MAX_NUM_DEVICES 32

Let me just say that I am a linux newbie and am not yet entirely comfortable getting around in it. I had a look at the contents of the ntop tarball that I'd downloaded and can't find a globals-define.h. Am I looking in the wrong place? Or is that a reference to a source code file? I haven't a clue how to recompile it. Don't mean to come across as requiring spoon feeding but it's not so easy to hit the ground running.

I specify eth0, eth1 & eth2 in the -i command-line parameter and then when I run ntop it automatically adds the virtual interfaces on eth2, which is great. However, it seems to stop at eth2:7 (a total of 10 interfaces). Anyone know if this is a hard-coded limitation or whether it is configurable?
