Hi all,

I searched www.google.com and cannot find a ready ip_conntrack_h323.o, just
ip_conntrack_h323.c source code.
I don't know how to compile this source code to a ip_conntrack_h323.o
module. I read the code file and found that I already got all the ".h" head
file.
Please help me to compile this module.

look if there is a source package it belongs to, download that, untar, cd into that directory and do ./configure && make && make install

if there really is only that file then you need to look into how gcc works

It is it's own source - it's a patch for iptable's connection tracker that allows the use of Netmeeting (which opens up artbitrary ports and hence the patch is needed to listen for what ports to open up).

I'm going on memory here, 'cos I compiled mine in a long time ago. But you should have more than just the c file.

You could have a 'patch' file which you need to diff with a Makefile in your /net source directory. The patch will insert the correct makefile instructions to create your object file (.o) for your machine.

I see, after doing a little research, that I might be wrong on the above. The process has come a long way since I did it. openh323.org provides a download, an instruction page, and a list of common errorrs :

Follow the above and if you have problems post at which stage...

Hi,

I do download the openh323 and pwlib package from that www.openh323.org . I just unpack the files and compile them according to the readme files. But nothing changes after that. When I ran "make install', it just copied some files to /usr/local/lib and /usr/local/include folder. Then I also add /usr/local/lib to "/etc/ld.so.conf" and run "ldconfig" to make it work. However, you know, I'm so disappointed to find I still couldn't do voice chat through that RedHat NAT server.

Well, it's not easy to get Netmeeting working with NAT.

Especially since they moved from the ils (internet locator service ?) to um.. whatever it is they use now.

I don't do netmeeting outside of a work environment and I built my own ils server to which all the netmeeting clients connect. I know they changed the way Netmeeting 3 works, although I believe you can still use an ils service. I recall reading about the changover (which happened in about 1999 I think) and didn't like it one bit.. So, never migrated.

Anyway... Your problem could be the lack of LDAP support (I'm reading the documentation and surmising here.. I've not done any of this myself).

The following link is the HOWTO on getting Linux to talk to and use Netmeeting.

See if that helps?
