Surge DHCP 无法正常开启

alexzhao

之前一直开启 surge dhcp 做软路由，稳定运行了一年多了，今天发现一直在报错，尝试重新安装 surge helper 也不行。

dhcp 日志如下：

运行在 intel 芯片的机器上。

补充一下版本信息，使用最新的稳定版本：Version 5.1.2 (2265)

DHCP 服务端口号冲突，请先重启，并排查是否有其他服务开启了 DHCP。

我也遇见这个问题了，突然就这样了，没做任何调整，也没新装软件。

手动杀掉 67/68 端口占用的 bootpd 进程就能正常启动了，但是只要重启macmini，这个 bootpd 开机自启，
之前没留意，不知道之前为什么不会有这个问题。

今天又遇到了此问题，发现确实遇到了端口号冲突的问题，终于成功解决了，这里记录一下：

❯ sudo lsof -i :67
COMMAND  PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
launchd    1 root   15u  IPv4 0xe266e99ee0d4eae7      0t0  UDP *:bootps
launchd    1 root   25u  IPv4 0xe266e99ee0d4eae7      0t0  UDP *:bootps
launchd    1 root   54u  IPv4 0xe266e99ee0d4eae7      0t0  UDP *:bootps
launchd    1 root   55u  IPv4 0xe266e99ee0d4eae7      0t0  UDP *:bootps
bootpd  3970 root    0u  IPv4 0xe266e99ee0d4eae7      0t0  UDP *:bootps
bootpd  3970 root    1u  IPv4 0xe266e99ee0d4eae7      0t0  UDP *:bootps
bootpd  3970 root    2u  IPv4 0xe266e99ee0d4eae7      0t0  UDP *:bootps

这里需要禁用掉 bootps 的服务即可。

sudo launchctl unload -w /System/Library/LaunchDaemons/bootps.plist

Trowel6700 你可以尝试看我上面最后一行,取消开机自启.

Trowel6700

alexzhao 确实是有效的，我只是好奇，为什么突然间就变成这样了，我只是办了个家，设备没动过配置

alexzhao

Trowel6700 我基本也是同样的情况，没感觉动过什么。

usrnm

什么也没动，Mac mini上只安装了surge这一个文件，突然遇到这个问题，按照 alexzhao 的方法解决了

alexzhao

@SurgeTeam 我本人今天还是遇到了这个问题(在 macOS 升级后),使用我上面提到的方法后解决,不知道 surge 能否添加一个检测之类的避免后来人也遇到此问题.

系统一直保持运行状态，突然就dhcp报错。使用你的方法解决了，谢谢。
