Ah, maybe give it a fixed IP address :)

Sorry - not much help.  I can see where it could possibly cause problems
even if it gets the same IP every time.  I'm sure someone (Luca, Burton,
et all) could fix it - but it's beyond what I can do.

If your machine NEEDS a DHCP addy with a ~ 24hr lease, maybe add a
second NIC to your system with no ip just for ntop?  Again, doesn't
"fix" the code but does resolve the problem.

Subject: [Ntop] Ntop 3.3.7 Crashes On DHCP Lease Update

As I mentioned in a previous e-mail to this list, I've built Ntop 3.3.7
on Fedora 9. This was successful, except for this problem.

The computer I'm testing this on uses DHCP to obtain its IP address.
Every time this happens, this new version of Ntop crashes. It's happened
three times now. Each time, this is the output as shown in the syslog:

Aug 19 01:48:15 ge40403 dhclient: DHCPREQUEST on eth0 to X.X.X.65 port
67
Aug 19 01:48:15 ge40403 kernel: ntop[1255]: segfault at 38 ip 00204d63
sp b1e665c4 error 6 in libntop-3.3.7.so[1bf000+65000]
Aug 19 01:48:15 ge40403 dhclient: DHCPACK from X.X.X.65
Aug 19 01:48:15 ge40403 kernel: device eth0 left promiscuous mode
Aug 19 01:48:15 ge40403 dhclient: bound to X.X.X.70 -- renewal in 41094
seconds.

I've removed the IP network address for privacy reasons, but those X's
represent the same three numbers each time.

This doesn't happen when I run Ntop version 3.3 on the same system. I'm
running the new Ntop now with the --disable-decoders flag set to see if
the problem is in the decoders.

Has anyone else encountered this problem? If so, is there a fix?
