linux ssh 登录管理

@(Linux 命令脚本)

功能类似 xshell 这类终端管理工具，将需要登录的机器ip信息统一记录在一个host文件中，登录直接选择对应序号就好，减少重复输入ip，账号。

登录脚本 jump.sh

#!/bin/bash
# by orientlu

if [ !-f "host.list" ]; then
    echo "Cant't find host.list"
    echo "host.list : IP name passwd port"
    exit -1
fi

clear
echo "====================================================="
echo "Host list : "
awk '{printf("(%d) IP : %s\t%s\t%d\n", NR, $1, $2, $4)}' ./host.list
echo ""
echo -n "Number : "
read -r number

eval $(awk -v number="$number" '{if(NR==number){printf("ip=%s name=%s passwd=%s port=%s", $1, $2, $3, $4)}}' ./host.list)
echo "SSH : " $ip

expect ssh.exp $ip $name $passwd $port

自动填写 ssh 密码脚本

set timeout 1200
set ip [lindex $argv 0]
set name [lindex $argv 1]
set passwd [lindex $argv 2]
set port [lindex $argv 3]

spawn ssh -p $port -l $name $ip
    expect {
        "yes/no"  {send "yes\r"; exp_continue}
        "assword:" {send $passwd\r";}
        expect eof
       }
sleep 1
interact
