编辑 ser2net.yml 并重新启动 docker 后，无法在 docker 容器上重新启动 ser2net

/etc/ser2net.yml在 docker 容器中编辑文件。

  • 在 ser2net 文件中添加了以下条目：

    connection: &con40000
    accepter: tcp,40000
    enable: on
    options:
      banner: *banner
      kickolduser: true
      telnet-brk-on-sync: true
    connector: serialdev,
              /dev/ttyUSB0,
              115200n81,local nobreak

  • 重新启动docker容器：

    docker stop my_container
docker start my_container

  • 回到容器中

    docker exec -it my_container bash

    但重启失败ser2net:

    $ systemctl restart ser2net
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down

这是完整的ser2net.yml文件

好的，感谢 @realpclaudio 指出 - 它没有实现 systemd。

以下两种解决方案有效：

$ docker exec -it hacpy_container pkill ser2net
$ docker exec -it hacpy_container ser2net -c /path/to/ser2net.yml
Unable to start mdns: Out of memory #<- this still restarted ser2net

和

$ service ser2net restart 
Unable to start mdns: Out of memory #<- this still restarted ser2net

最初，我对这个问题有点困惑无法启动 mdns：内存不足但它并没有导致ser2net端口映射出现任何问题。
