H323

H323

[gold gold]

Hello everybody,



     I've already asked this question before, but here it is again:



How do I enable my masqueraded Windows machine to use MSN's audio/video 
conversation? I've been told to load the "H323" module and do some 
"patch-o-matic stuff" (??), but I don't really know alot about these 
stuff... could someone please give me detailed step-by-step instructions on 
how to do that? I would really appreciate this. Thanks a lot.

In general it is not so hard to apply and activate the H.323 patch.
you have to
1) download iptables, download POM(patch-o-matic) for the proper version of 
iptables i think
2) have the kernel source of course 
3) untar&unzip everything (I have done this in /usr/src)
than
4) I do a backup of my compiled kernel directory and than start making all the 
rest to avoid recompiling everything 
5) apply the patches (there is info how to do this in POM itself and you don't 
need to apply patches that you won't use and know - try first only the H.323 
patch)
6) reconfigure your kernel and enable H.323 (networking options => ip 
netfilter configuration)
7) (re)make your new kernel
8) change into iptables dir and make "make KERNEL_DIR= ... " path to your 
kernel 
make install
9) enable your kernel (ex. make install, make modules_install - change lilo, 
grub, boot, make initrd or anything you use)
IMPORTANT TIP
10) Be sure to have a rescue floppy or entry in the bootloader for the old 
kernel to be able to boot your old configuration in case of failure
- --------------
If it's just you staying behind a firewall and useing  netmeeting and you have 
rights to manage the firewall, you can forward the ports (1720 and few 
others) to your windows machine (google tells you how)

best regards and good luck

There is a good document that explain the process?

Thanks a lot!!!!

H323

[Jeffrey J. Karrels]

Hello,

I am trying to get Netmeeting/Remote Desktop Sharing to work.  I have
2.4.20-30.9 kernel and am running iptables-1.2.9.  I have patched the kernel
with the only the H323 patch.  I opened up the 1720 and 1503 ports.  I get
the following message in my syslog when I try to open up an connection from
the outside going in:

H.323_NAT: partial packet 0/6 in 0/0

I have seen this in the mailing list a couple of times, I was wondering if
anyone knew anything about it? Any suggestions?  Am I missing something?

Thank you
-Jeff

Re: h323

[Scott van Looy]

You'll need to be happy building your own custom redhat kernel -

install from source patch-o-matic, adding the h323 patch
recompile kernel, then boot into kernel
install from source iptables

then make sure your modules are loaded
/sbin/modprobe -k ip_nat_h323
/sbin/modprobe -k ip_conntrack_h323

open ports 1503 and 1720 (389 and 522 if you want to use ils)

and it should just work!

MSN telephoy does not use H.323 and therefore is not supported by
iptables.

IIRC MSN messenger can be configured to use a socks proxy like dante

Re: H323

[Eric Wood]

I think netfilter can do the job.  You'll need a gatekeeper to do this:

Here's a few:
OpenGK gatekeeper translates between user aliases and IP addresses. Makes
your life easier.
OpenH232Proxy is a gatekeeper with built in proxy feature. It enables the
routing through the gatekeeper of the RTP traffic (audio and video) and the
T.120 traffic (data) so no traffic is directly exchanged between endpoints.
(This one is not in the distro yet.)
OpenMCU H.323 conferencing server lets you hold virtual conferences. simply
connect to openmcu server instead of connecting to another gnomemeeting
client, and you are ready to go. If installed on a firewall (and visible
from both sides), openmcu can serve as a proxy.


I've got OpenH232Proxy sort of working for my cams.

in the kernel). However, I am still not able to get netmeeting working over
the NAT server. Is there any detailed documentation that I could refer to?
Also, is there any way I could get MSN voice chat and file transfers to work

the IP address of the ethernet card connected to the Internet.

Please assist.

H.323 (including netmeeting) will work fine with the H323 modules.

You cannot, however, use call servers (I don't remember, what they're
called) along with NAT.

hi,

ive got a network masqueraded by iptables to internet.
my clients (the one who are masqueraded) ask me for neetmeting and h323
stuff that does not work....does the h323 module for iptables permit
such transmissions?

or should i try to set a h323gatekeeper on the firewall?

Hi, just wondering if anyone has the same problem.

Fresh copy of 2.4.19 and iptables 1.2.7a with patch-o-matic and used the z-newnat and h323 that comes with it.. fixed the newnat patch which couldn't load. add 2 lines to a ip_conntrack.h file and it worked fine. We send audio fine but can't receive it.. possibly the same problem with video too...

Hi, Diego.

I have questions.
does the new nat patch have h.225ras, or ldap for NAT problems.
before, when i applied the h.323 patch, the patchs
have a part of h.323, but not h.225.
Is that ok?

Can you use ILS server, or Gatekeeper?

Iptables has h323 modules, too.
You have to apply kernel-patch of patch-o-matic.
 But, I think h323 modules is not perfect...

h323

[Mattia Martinello]

Hi

I am on a LAN which access to the Internet with a NAT on a gateway Linux 
server configured with iptables.
How I can use on a client inside the LAN a program which uses h323 
protocol, for example Microsoft Netmeeting? I wish to correctly use 
text, audio and video features of Netmeeting, and I wish to call and to 
be called.

How I can configure the firewall on the gateway server?
I rememeber that for ipchains there was an h323 module. There is 
anything for iptables too?

Thank you very much
Bye
