| - | ===== socat Linux tool for mapping IP addresses ===== | + | ==== On Linux ==== |
| + | |||
| + | The socat tool can be used to access the serial interface tunnel via the console using TCP. | ||
| + | |||
| + | The first command is for the connection between IP address and ser2net server on the router | ||
| + | |||
| + | <konsole> | ||
| + | ~ $ socat PTY,link=/dev/"virtual interface",echo=0,wait-slave TCP:"IP-adresse":"port-nummer",retry=5 | ||
| + | </konsole> | ||
| + | |||
| + | In a second console, the virtual interface is then used for the connection to the serial interface. | ||
| + | |||
| + | <konsole> | ||
| + | ~ $ socat STDIO,raw,echo=0,escape=0x03 /dev/“virtual interface“,raw,echo=0 | ||
