I am trying to run a SSH command from a PHP script using shell_exec or system:

system("ssh [email protected] remote_command");

which used to run fine until the most recent versions of PHP and Cygwin OpenSSH. Now it just hangs indefinitely.

I discovered that if I redirect the command to a file:

system("ssh [email protected] remote_command > output.txt");

The command completes and the output is redirected to the file.

I also did a clean install and in that instant it starts returning output and stalls halfway through.
