Ntop is a great tool. I use to have the 3.2 version
installed from a RPM on a Fedora 4 machine and that
one use to be kind of stable.

Lately I got the latest stable version from
http://downloads.sourceforge.net/ntop/ntop-3.3.tar.gz
and compiled that on Fedora 5 and Fedora 4 because I
found no RPM available. All dependencies solved and it
did compiled OK.

I start Ntop with a command like:
ntop -u ntop -i eth1 --daemon --use-syslog=daemon
--no-promiscuous --no-fc
or
ntop -u ntop -i eth1 --use-syslog=daemon
--no-promiscuous  --no-fc &

Unfortunatelly it will stay up for a while (10 min to
xx days) and then will crash with an error similar to:

FC4 crash

Any Ideas?

Also 3.3 does look great but is slow over a satellite
connection compared to 3.2.
