Trying to use plink for a project and running into problems on Windows 7 x64. It simply goes to a blank line and hangs there. On a 32-bit XP development machine it runs as expected. We have tried XP compatiblity mode but it did not help.
The solution ended up being to run commands through a simple PHP page. The connection was internal to our network and we weren't worried about encryption, just remotely triggering a command and getting the output. There must have been another command line scripting tool we could have used but the approach we took ended up being very simple and met our needs.
