打洞失败能否报错退出？

[ArenaDruid]

使用了Natter-qBittorrent的镜像，有时能通有时又不能通。

不能通的时候，我经常是重启一下natter容器又能通了，请问有什么办法设置不能通的话尝试重新打洞，或者报错退出（这样我可以使用docker的restart策略）。

[MikeWang000000]

Natter 有一个 -q 选项，可以在外部地址发生变更时直接退出。请问此选项是否有效果？

不行，有时首次启动就是打洞失败的，如日志所示

如同日志所示，第一次尝试直接打洞成功，在外部地址变更后退出，docker restart策略执行重启
第二次尝试（docker自动重启）打洞失败，没有退出，一直保持没有实际工作的运行状态
第三次尝试（手动重启）打洞成功

作为临时处理，您可以这样修改 natter.py：

找到：

            Logger.warning("!! Hole punching failed !!")

改为：

            Logger.warning("!! Hole punching failed !!"); sys.exit()

这样就会在输出 !! Hole punching failed !! 之后退出了。

我会在下一个版本考虑这个需求。
