Transparent proxy server that works as a poor man's VPN. Forwards over ssh. Doesn't require admin. Works with Linux and MacOS. Supports DNS tunneling.

Typically sshuttle exits by having the main sshuttle client process terminated. This closes file descriptors which the firewall process then sees and uses as a cue to cleanup the firewall rules. The firewall process ignored SIGINT/SIGTERM signals and used setsid() to prevent Ctrl+C from sending signals to the firewall process. This patch makes the firewall process accept SIGINT/SIGTERM signals and then in turn sends a SIGINT signal to the main sshuttle client process which then triggers a regular shutdown as described above. This allows a user to manually send a SIGINT/SIGTERM to either sshuttle process and have it exit gracefully. It also is needed if setsid() fails (known to occur if sudo's use_pty option is used) and then the Ctrl+C SIGINT signal goes to the firewall process. The PID of the sshuttle client process is sent to the firewall process. Using os.getppid() in the firewall process doesn't correctly return the sshuttle client PID. |

sshuttle: where transparent proxy meets VPN meets ssh
=====================================================
As far as I know, sshuttle is the only program that solves the following
common case:
- Your client machine (or router) is Linux, FreeBSD, or MacOS.
- You have access to a remote network via ssh.
- You don't necessarily have admin access on the remote network.
- The remote network has no VPN, or only stupid/complex VPN
protocols (IPsec, PPTP, etc). Or maybe you *are* the
admin and you just got frustrated with the awful state of
VPN tools.
- You don't want to create an ssh port forward for every
single host/port on the remote network.
- You hate openssh's port forwarding because it's randomly
slow and/or stupid.
- You can't use openssh's PermitTunnel feature because
it's disabled by default on openssh servers; plus it does
TCP-over-TCP, which has `terrible performance`_.
