Topic: VideoPhone software

[Tommy Tong]

Well my connection is back up and everyone else in the house has their internet connection again but there is now a new problem. I just bougt a USB camera and was playing with the Intel videophone software and MS NetMeeting when my Windows machine was directly connected to the cable modem. Now with everything going through the e-smith box, neither will work. What can I do to make either of these two work? I don't know what port either of those programs use. Is this a surmountable problem? Are there any programs that work properly "out of the box"?

I guess this is the same problem that streaming Quicktime 4.0 is having, right?

Thanks in advance.

I don't know either. And you don't have the source, do you?

There is a movement to develop Open Source, Standards compliant video conferencing software. Go look at http://www.openh232.org/
and see what you can find.

No idea, sorry.

I don't think this is fixable atm - it's a big problem for all firewalls as H.323 needs lots of special trickery to work...Charlie's link can get u started in reading up on it (www.open323.org), but Intel's site & Phrack have some good write-ups.

Nope, this will be different & should be easier to fix, though I've not seen an ip_masq_quicktime yet...
It already supports Real Audio & VDOlive through this method.

The basic proble with this is as I understand it that in order to masquerade
H.323 you must also change bytes inside the data of the package. Normal masquerading only change headers. To complicate matters further, the location
inside the data is not fixed, it depends on the rest of the contents. The only way
to do this is to 'understand' the protocol. To do this you need a special application
proxy. Last time I looked for it (a long time ago) none were available for 'us'.
