| 3 | +usage 'pinhole port host [newport]' | |
| 4 | + | |
| 5 | +Pinhole forwards the port to the host specified. | |
| 6 | +The optional newport parameter may be used to | |
| 7 | +redirect to a different port. | |
| 8 | + | |
| 9 | +eg. pinhole 80 webserver | |
| 10 | + Forward all incoming WWW sessions to webserver. | |
| 11 | + | |
| 12 | + pinhole 23 localhost 2323 | |
| 13 | + Forward all telnet sessions to port 2323 on localhost. | |
