Compatibility issue with Yahoo Messenger
The version noted in the list above has a compatibility problem with SOCKS5 type proxy servers.

Yahoo Messenger (YM) attempts to resolve the host name of the messenger service server. In doing so, it issues a TCP call. Unless you have a DNS server correctly configured on your network, the host name will not resolve and consequently, YM will fail to connect.

To overcome this problem you can either use the HTTP proxy setting (this works OK) or if you particularly want to use SOCKS5, then do the following.

  1. From the computer directly connected to the internet, start a DOS shell.
    Start -> Run
    If you have Windows 98 or Windows Me fill in command and press OK; or,
    If you have Windows NT, 2000, XP or 2003 fill in cmd and press OK
  2. Ping the server
    type the following
    ping scs.msg.yahoo.com
    and you should get a response similar to this

  3. Edit the local hosts file on each client. The hosts file on each client running Yahoo messenger can be found in these locations.
    On Windows 98 or Me: C:Windows
    On Windows NT/2000/2003/XP: C:WINNTSystem32Driversetc or C:WindowsSystem32Driversetc
    Edit the file using Notepad. Make sure the file you are editing is called hosts and not hosts.sam nor hosts.txt. The file name has no extension. Double check this.
    Place the following line into the hosts file. If the IP address you get in step 3 is different to the one shown above, use the one you get. scs.msg.yahoo.com

    The IP address starts in the first character position. There can be any number of spaces between the IP address and the host name. If you already have IP addresses in the host file, place this IP address at the end of the list. Positioning is not really significant.

    Save the file.
  4. Retry Yahoo Messenger

Please upgrade to the latest version of FreeProxy.
