i test this with ntop 2.0-debian, 2.1.3, 2.1.56 and cvs (from feb 7th)
on the following system: debian 3woody - i386 / autoconf 2.13, automake 1.6.3, gcc 2.95.4 (all deb)

with old (2.0) release, all ntop process quit but for cvs/snap/dev, only main/web/? thread quit and i cannot anymore access to ntop with web interface (intop works when available)


Regards

Julien
