现在linux下ssh使用比较广泛的是openssh包
ssh相关选项:
-V
显示版本: ssh -V OpenSSH_6.6.1p1 Ubuntu-2ubuntu2, OpenSSL 1.0.1f 6 Jan 2014
-f
输入密码后进入后台模式(Requests ssh to go to background just before command execution.)
-N
不执行远程命令,用于端口转发( Do not execute a remote command. This is useful for just for warding ports (protocol version 2 only).)
-D
socket5代理(Specifies a local “dynamic” application-level port forwarding.Currently the SOCKS4 and SOCKS5 protocols are supported, and ssh will act as a SOCKS server.)
-L
tcp转发(Specifies that the given port on the local (client) host is to be forwarded to the given host and port on the remote side.)
-C
使用数据压缩,网速快时会影响速度(Compression is desirable on modem lines and other slow connections, but will only slow down things on fast networks.The compression algorithm is the same used by gzip)
建立SOCKS5代理:
ssh -f -N -D bindaddress:port name@server
bindaddress: 指定绑定ip地址
port: 指定侦听端口
name: ssh服务器登录名
server: ssh服务器地址
例: ssh -f -N -D 127.0.0.1:1080 xiaomi@158.211.221.121
这样就建立SOCKS5代理。
使用SOCKS5代理
例:
chrome: chrome需要使用命令指定SOCKS5代理:
google-chrome –proxy-server=”socks://127.0.0.1:1080″
firefox:
在preferences=>advanced=>Network->connection->Settings里,勾选Manual proxy configuration,并将其它项清空,SOCKS Host设置为127.0.0.1,port设置为1080, 并勾选Remote DNS(勾选后可防止本地DNS污染),如图。
