how to force skype to use tor network?

how about starting vidalia and tor and specifying 127.0.0.1 and 8118 in skype/options/connection (with https?/or socks5)?

 

I wouldn't trust it. Skype is closed-source and does all kinds of things behind the scenes with its routing. Maybe check the Tor project's home page and see if they have any guides on it. I am doubting it.

 

Search for "Microsoft Legal Intercept" and "Skype Super Node Change". I wouldn't use it. Switch to Jitsi and OSTel.

The Guardian Project has a ton of info, check CSIP Simple

PD

 

but video chat over msn messenger plus is secure right?

p.s: that ostel thing looks interesting

 

Last time I used Skype (a year or so ago), it was relying heavily on UDP, which can't be relayed through TOR, so I'm not sure you will be able to get full functionality in Skype over TOR.
Besides, if you didn't create the Skype account using TOR, or even if you did and used it at least once outside TOR, you can be identified.

 

Nearly all VoIP clients use UDP as it's far more suitable. TCP, if used, is usually a "fallback" mode.
