Re: ssh in C++

Hi Tom,

The option C seem to be the one to go forward with. I am using linux operating system and have root installed in it. My concer is how to have sshfs setup before trying to mount the remore com puter. I have spend time trying to figure out this, but still no break. Suggestions are much appreciated.
