Hi All,
I have been an observer and occasional user of ntop for nearly two years
now, but so far I have never found any version of ntop to be stable.
Every few months I grab the latest snapshot, cross my fingers, and give it
a try, but I always have the same problems:
On a moderately loaded system ntop will randomly run any time between a few
minutes and a maximum of about one or two days, before core dumping. It
*seems* to be triggered by interaction with the web interface, as it almost
always dies when viewing results pages, especially when clicking quickly
between different pages.
The second problem I have is I can never compile without threads, I always
get something like the following:
/bin/sh ./libtool --mode=compile gcc -DHAVE_CONFIG_H -I.
-I/usr/local/include -I/root/ntop-current/gdchart0.94c
-I/usr/include/openssl -g -O2 -pipe -c webInterface.c
rm -f .libs/webInterface.lo
gcc -DHAVE_CONFIG_H -I. -I/usr/local/include
-I/root/ntop-current/gdchart0.94c -I/usr/include/openssl -g -O2 -pipe
-Wp,-MD,.deps/webInterface.pp -c -fPIC -DPIC webInterface.c -o
.libs/webInterface.lo
webInterface.c: In function `printNtopConfigInfo':
webInterface.c:698: `packetQueueLen' undeclared (first use in this function)
webInterface.c:698: (Each undeclared identifier is reported only once
webInterface.c:698: for each function it appears in.)
webInterface.c:704: `maxPacketQueueLen' undeclared (first use in this
function)
make[2]: *** [webInterface.lo] Error 1
make[2]: Leaving directory `/root/ntop-current/ntop'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/ntop-current/ntop'
make: *** [all-recursive-am] Error 2
Yet compiling with threads does produce a working (but unstable) executable.
Over the last 2 years I have tried ntop on 4 different machines and always
have the same instability which seems to be triggered during viewing the
web based statistics pages.
The current machine I'm trying to run ntop on is a Dual PII-233 with 256MB
ram, plenty of disk space, running Redhat 6.2 with a 2.2.19 kernel. (But as
I mentioned, I've had identical problems on more than one other machine)
I can reliably trigger a core dump within a few hours or a day, so I'm
willing to help debug this problem by providing core dumps, etc. Please
advise what information would be necessary. I really like the features of
ntop and find it frustrating that I can never get it to run for long....
Regards,
Simon
