To report a bug in the 2.0.99-rc1 (2.1 release candidate):
1. Put RC1BUG in the subject along with a meaningful title
"ntop problem" won't do. "ntop seg faults in xxxx.c at line xxxx" is
great
2. Make explicit WHICH RC you are reporting this against. Where you got it,
etc.
"RC1, downloaded from ntop.org on 18May2002, built from source"
Also indicate if you have followed the procedure in BUILD-NTOP.txt to
make a static linked version OR are using shared libraries installed with
the OS.
3. Give a detailed explanation of the problem
4. Background information
The EXACT command line you use to invoke ntop. If it's in a script, cut &
paste it and resolve all the variables!
Web interface problems: The exact URL you used from the browser. (If you
are in the normal frameset, you may need to right click - open in a new
window - to see the url). Otherwise, give the FULL navigation, e.g. Data
Sent | Throughput, clicked on "Host" to sort)
Error Messages: Cut & paste the exact text. If it's in the log, give us 15
or 20 lines before.
If the problem is a segmentation fault, include the backtrace
(available with the gcc compiler if you specify the -K parameter). This is
only a minimal trace and may not give us the information we need, but it's
better than nothing.
For repeatable seg faults, please see instructions on using gdb at
http://snapshot.ntop.org and post the "info stack" and relevant variable
"print" command outputs.
4. Environment - please give the following information:
OS & Version (e.g. Solaris 8/i386 or RedHat Linux 7.3 or whatever)
CPU (type & quantity), Memory (e.g. 1 P3-800, 128MB)
# network interfaces and types (vendor, bus, etc.), plus where they are on
the network (e.g.
two NetGear RT311s (PCI), one on the internal network, one connected to the
cable modem). We're trying to see roughly where are the interface(s) you're
monitoring and what their bandwidth is.
How many machines (traffic sources/destinations) and users are being
monitored. (e.g. 10 hosts - 2 are very busy ftp servers, the rest user
workstations)
What else (other daemons) is/are running on the machine, load, etc. Again,
we're interested if this is a very busy, memory constrained machine, or ntop
has a dual Pentium 1000, with 1GB of ram to monitor a 56k dialup...
?s/Issues - sing out, but remember, more information is always better than
to little.
