svn checkout error

Hi,

When i execute “svn co http://llvm.org/svn/llvm-project/lldb/trunk/ lldb” to get the lldb source,

i am getting the following error message:

svn: OPTIONS of ‘http://llvm.org/svn/llvm-project/lldb/trunk’: could not connect to server (http://llvm.org)

I am not able to mak out the exact reason, i have enabled to access port 80 for svn access.

Do i need to access any other port (i.e. port 22 etc)… or i need to check any other configuration?

please help on this.

regards,
Tyagi
