有关peer中突然多出来的一个PublicServer节点疑问

[bczhc]

如图，就在今天使用easytier-cli peer查看VPN节点列表时，发现多出来了一个叫PublicServer_aliyun-hangzhou的节点。很奇怪。在此之前是一直没有过的。如图：

我的网络配置大概是，有个有公网的海外服务器上启动了easytier服务，其他地方的客户端去加上这个服务器作为peer以此组网。家中的ipv6自换了光猫后不能ipv6入站，故利用这个海外服务器作为协商者打洞，让其余彼此建立ipv6 p2p连接。从没配置过使用easytier公共服务器。

命令类似于：

海外服务器：

sudo easytier-core --network-secret='xxxx' --network-name=xxx -i 192.168.5.1

其余客户端：

sudo easytier-core --network-secret='xxxx' --network-name=xxx -i 192.168.5.x -p udp://海外服务器

查看event log，会有一个network_name为sijie-home的peer加入。ip地址为47.111.68.133，确认是上方所显示的PublicServer_aliyun-hangzhou。

查看除海外服务器的我的另外两个设备上easytier的日志，发现最早在2月12日0点21分加入。

2月12日凌晨我没在操作任何东西。所以有点没头绪。

单单在海外服务器上重启easytier，这个PublicServer依然会显现；把所有设备包括此海外服务器的easytier都重启，这个PublicServer消失了。

[woqucc]

我也一样，出现 PublicServer_xxxx, xxxx是网络中已有的一个节点的名字.如果不是程序bug的话，是不是有人在尝试扫描爆破进入网络引起的？

[bczhc]

那不知道呢。我的这个PublicServer_aliyun-hangzhou只是个et公共服务器，使用其ip 47.111.68.133在easytier repo里搜索也能确认。sijie-home在 #949 里有出现，大概是作者的名字。网上搜到了这个和我的情况一样，不过没有回复。但我是真的没能想出为什么。那一天的凌晨我在做其他的，在来回重启电脑二分一个linux内核bug，无论是凭记忆还是看shell history都没碰easytier任何东西。可看日志它这个PublicServer_aliyun-hangzhou就这么莫名在那天凌晨出现了。我之后重启了所有的节点设备，它就没了，一直用到现在也没再出现。不管它了，没头绪。
