I am woking in mainland China, so I have to use VPN to open the page of youtube when I am in China. However, since November 2012, I can't open it again with my MacBook Pro (OSX10.7.5 Lion) through the VPN account. But  I can open the page of youtube with my old PowerBook G4 (OSX10.4.11 Tiger) through the same VPN account. Why? Can anyone help me to fix this problem? Thanks

MacBook Pro, Mac OS X (10.7.5)

    Possibly blocked by the Government.

    Can you open other pages? What happens when you try to open YouTube? Have you tried a different VPN?

    If the other end of the VPN tunnel is outside China, and the tunnel is working, then you should not be affected by the Internet restrictions in China. From your description, it seems that the tunnel is not working, or the endpoint is inside China. It may be that the authorities have found a way to break into the tunnel. Please use caution. That's all I can tell you from the information provided. I don't know why it's working on your other computer.

    I can think of one possible reason why you might get different results from the same VPN with two different computers.


    Your browser sends a user-agent string to server, identifying its version and the platform it runs on. Some web servers adapt the content they server to the agent. For example, if you connect from a mobile device, you may get a different version of the site optimized for such devices.


    If the VPN passes through the agent string, the server may decide that an old PowerBook can't handle the same video resolution as a new MBP. So maybe it sends higher-bandwidth video to the MBP. Maybe also the VPN can't handle that higher bandwidth.


    You can test the theory by copying the agent string from Safari on the PB to Safari on the MBP. I don't remember how you do that in Tiger, but in ML you enable the Develop menu in Safari's Advanced preferences.

    The user agent string doesn't depend on which website you're connecting to. It only depends on the browser. What I'm suggesting is that you copy the user agent string from the PowerBook and test it on the MBP.
