mac 利用 sshpass 自动登录

mac 利用 sshpass + 配置文件实现自动登录

使用方式 https://github.com/vipzhicheng/go 参见此项目

其实原理也就是脚本读取配置文件匹配参数或者 ip 调用 ssh 命令简单 mark下

按照链接方式配置好之后

shell 中执行 go (参数)

例如我配置

# IP USER:PASS Label

120.27.96.210(你的 ip) 你的用户名:你的密码 label:210

执行 go 210

直接 ssh 登录到目标 ip

#!/bin/bash

# Define config directory and config path
GO_HOME=~
AUTHFILE=$GO_HOME/.ssh/pass/.go.conf

# Parse options
while getopts gh ARGS
do
  case $ARGS in 
    g)
   extra_options="-D7070"
    shift
   ;;
    h)
        echo "usage: go [-gh] foo bar"
        exit 0;
    ;;
    *)
        echo "Unknow option: $ARGS"
        echo "usage: go [-gh] foo bar"
        exit 1;
        ;;
  esac
done

sshpass -p $passwd   -P $port  ssh $user@$target  //利用 sshpass 不会出现第一个命令 会卡住现象  expect命令会出现 原因不详

#ssh-expect $user $target $passwd $port $extra_options $sshkey
