If I reboot the second Raspberry (PiZero2-1), the problem persists. but it is not working from the other end. └─597 /usr/bin/ssh -tt -R 19999:localhost:22 -p 2222ĭic 20 18:01:41 PiZeroW-1 systemd: Started reverse ssh tunnel service.ĭic 20 18:02:04 PiZeroW-1 ssh: Linux PiZero2-1 5.10.63+ #1488 Thu Nov 18 16:14: armv6lĭic 20 18:02:04 PiZeroW-1 ssh: ĭic 20 18:02:04 PiZeroW-1 ssh: The programs included with the Debian GNU/Linux system are free software ĭic 20 18:02:04 PiZeroW-1 ssh: the exact distribution terms for each program are described in theĭic 20 18:02:04 PiZeroW-1 ssh: individual files in /usr/share/doc/*/copyright.ĭic 20 18:02:04 PiZeroW-1 ssh: Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extentĭic 20 18:02:04 PiZeroW-1 ssh: permitted by applicable law.ĭic 20 18:02:04 PiZeroW-1 ssh: Last login: Mon Dec 20 17:54:58 2021 from $ ps -ax | grep sshĦ19 ?
