  • NETGEAR(R) ProSafe(R) GS105E Ethernet Switch Review

    About several months ago I was considering buying a new gigabit ethernet switch that has 5 ports (so it’s small enough to fit even on my desk). I already had an unmanaged switch at that time – a TP-LINK TL-SG1005D, 5-port gigabit ethernet switch, but as I was planning to put some devices in the lab, I need another switch to allow more devices get connected to the same network. I searched for gigabit switches on Taobao, and at some time this NETGEAR GS105E switch appears in my eye.

  • Tor 实践

    Tor 在这里*无论是直连还是接网桥都是已经做不到的了,尽管 Tor 的开发者一再声称 Tor 所使用的网桥协议 obfs4 可以躲避任何侦测手段,然而因为实现上的小缺陷(而不是协议本身,协议是完美的1)现在墙也可以侦测到 obfs4 流量并进行拦截了,所以现在一个通行的办法是用 Shadowsocks 先穿出去,然后让 Tor 走 Shadowsocks 来连接洋葱网络。

    1. 盖子这么说的。
