I\'ve read several other \'git hangs on clone\' questions, but none match my environment and details. I\'m using git built under cygwin (msys git is not an option) to clone
An outdated PuTTy can also cause this. Your system might be using plink.exe as GIT_SSH.
You can install the latest development build from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html to make sure this is not the problem.
