Re: Use GnuGK with Rtpproxy

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi,

Please help to advice me. I want to do this thing:
- create a user on GnuGK
- Run Gnugk as a proxy of Extern Public IP and Internal User like bellow scenario:
User A (behind NAT) ---- register to --- (Public IP - Nic 1) Gnugk --- (Private IP - Nic 2) --- Internal GK -- Internal User B.

So, my question is:
- How do i create a user in GK? Sorry for first basic on. Do i need to compile with SQL for user starage and authenticate?
- Could i run about Scenario? make call from User A to User B and vice versa?

Thanks,
-LN

Hi,

Thanks Andrew again for this notes.

Btw, compile on 64bit, you should edit file include/ixjlid.h and comment out line

#include <linux/compiler.h>

Thanks,

Here are my notes on how to compile on Debian 4.0
 

Do the following as a regular user not as root

  • make sure you have OpenSSL headers, flex and bison installed 
sudo apt-get install libssl-dev flex bison
./configure
make optnoshared

./configure
make optnoshared
  • download Gnu Gk from CVS
    • do this from home folder 
cvs -d:pserver:anonymous@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:/cvsroot/openh323gk login
cvs -z3 -d:pserver:anonymous@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:/cvsroot/openh323gk co -P openh323gk
cd openh323gk
./configure --disable-mysql --disable-firebird  --disable-pgsql  \
            --disable-radius --disable-unixodbc --disable-sqlite
make optnoshared

When compiling is complete, the binary is here: 

~/openh323gk/obj_linux_x86_r/gnugk

Hi,

I have a little bit confused about PTLIB.

When compile pwlib, it also compiled ptlib.

But i also compile Ptlib_v2_0_1 and set PTLIBDIR:

export PTLIBDIR="/home/htklabs/pwlib/include/ptlib"

But in ~/h323plus, ./configure told that:
"Cannot find ptlib - please install or set PTLIBDIR and try again"

Please give your advice.

Thanks,
-LN

Hi,

compiling Pwlib 1.10.3 works on 64 bit if you disable a few modules
that GnuGk doesn't use anyway. I use this:

./configure --disable-video --disable-alsa --disable-openldap --disable-expat --disable-sasl --disable-sdl  --disable-ipv6

But since you want to compile 2.3.0 with H.460.18 support, you should
use H323Plus (from htp://www.h323plus.org) and use this patch for
src/Makefile
http://www.gnugk.org/download/src-Makefile-h46018.patch
or use the CVS version.

Regards,
Jan
