How to access any machine through reverse SSH tunneling.

Things needed:

Restricted Machine: Machine unaccessible remotely that we want to have access.

	# Make sure the script is made executable. (chmod +x gdb)

	# For local development (will open a dialog for entering password)
	pkexec /usr/bin/gdb "$@"

	# For remote development (add gdb to /etc/sudoers, hence it can be run without password)
