ubuntu24.04如何通过systemd开机后将22端口转发到公网？-灵析社区

nat.sh文件内容如下 #!/bin/bash local_ip=127.0.0.1 remote_ip=公网服务器ip remote_port=22 remote_user=root remote_password=服务器密码 target_port=("22:22222") for item in ${target_port[@]};do array=(${item//:/ }) the_local_port=${array[0]} the_remote_port=${array[1]} /usr/bin/ssh -o ServerAliveInterval=60 -o StrictHostKeyChecking=no -o ExitOnForwardFailure=yes -N -f -R $the_remote_port:$local_ip:$the_local_port $remote_user@$remote_ip -p $remote_port done 我将公钥放到了公网服务器，所以不需要密码的。 我手动执行这个nat.sh是没问题的，一切正常，但是开机启动就报连接公网服务器无权限。 我的开机启动脚本内容如下 [Unit] Description=nat After=multi-user.target [Service] Type=simple User=tom ExecStart=/home/tom/nat.sh Restart=always [Install] WantedBy=multi-user.target 错误日志 Jul 25 14:17:06 konka systemd[1]: Started nat.service - nat.
