201030 rcmd is a reverse (from cloud to home) remote shell access program. I started this project since I could ssh to my server from home, but couldn't ssh home from my server since my ISP blocks inbound traffic. The program runs in daemon mode at home and in listen mode on the server. The program uses a simple symmetric encryption using a key which can be generated randomly. To compile the program, run 'make' within the source directory. Run './rcmd -h' to see all available options.
