Fixed buffer overflow problem

Hi

Ive just installed Ntop-3.0 out of ports on FreeBSD-4.9.  Now all our
servers are FreeBSD 4.9, and on a few of them, i get the following errors.
And this is a clean install of Ntop-3.0.
All the servers im having problems on are not even the same hardware. But
they are all running the same kernel and same environment.  The funny thing
is, it happens on some, and not others, so i was wondering if any of you
have any ideas or any suggestions as to how to fix this or at least why it
is happening and can point me in the right directions.

Oh, Ntop has full read/write access to those plugins, and they are all in
that specified directory. And they were all installed when Ntop-3.0 was
installed out of ports.

Thanks
/Cole

Heres the Errors.

Hi,

Any fix has been released for the bug "gzflush error(-2)" ? ? ?

I have updated the redhat kernel to 2.4.21-15ELsmp. 

I have tried to compile the ntop with and without zlib, but the result is same (no html page response to user).

Please advise.

Wayne

Not a clue.  I've tried a couple of times to get the ports updated with
versions I understand, but my submissions get ignored.  So take it up with
whomever is packaging it.  Or try my port package in the source tree.

Nobody is working on it that I'm aware of.  Basically it doesn't fail for
Luca or me...

The zlib folks thought it was some type of memory corruption in the malloc()
chains, but the only way to catch that would be for somebody for whom it's
failing to run under valgrind and catch it.

The init.d/ script in the ntop source tree has a valgrind option, so it's
possible - you'll need a current valgrind installed and then try
/etc/init.d/ntop valgrind.

Then let it run and see if there's anything obvious in the valgrind logs.

Hi Buton,

I found the problem is seems solved, when my browser disable HTTP/1.1 option. 

is ntop support HTTP/1.0 request only ?

Wayne

Nope.  But there are some differences in the 1.1-style request.

Again, the only way to figure out what's up is to run under valgrind or
another memory allocation monitor.

Hey

The problem occured on the machine i built it on. I installed and compiled
everything on that machine, and it gave me errors. I built the package from
ports. Downloaded .tgz. compiled, installed. and ntop runs, but it gives out
those errors.

This isnt before moving it or anything, it was built on that pc, and thats
the one that is giving the problems.

The message is a simple pass through from the underlying OS function. ntop
tried it, it failed, here's what the OS said. Bada-bing Bada-boom...

I notice, Googling for the error message, that you received no reply from
the FreeBSD list...

Something is wrong with your setup.  No clue what.  But there are lots of
FreeBSD uses - last time the stats were run (3Jun), it was 394 FreeBSD
4.9...

Go back and READ the output from your make - there will be errors or
warnings in there, likely that you ignored... don't ignore, fix...
