使用场景： 一个的装有ssh服务端的服务器需要连接外网安装依赖， 但是 1. 服务器没有外网 2. 服务器所在局域网内的电脑没有外网或不方便设置成代理服务器 3. ssh客户端和服务器只有一个ssh端口可以连接 4. ssh客户端可以访问外网 以ssh服务器远程方式是ssh -p 11170 [email protected]为例， 要求本地和服务器都装有ssh服务端。 第一步： 在本地客户端执行， 将服务端2200端口映射到本地22端口 ssh -R 2200:localhost:22 -p 11170 [email protected] -N 第二步： 在服务端执行, 设置socks5代理， 监听端口是10800 ssh -D 10800 -p 2200 [email protected] -N 这时服务端就可以使用代理网络： curl –socks5 […]
