远程批量抓取Ubuntu PC信息的脚本


远程批量抓取Ubuntu PC信息的脚本(多个脚本分工完成)

 

有多个知识点:

a、  带密码ssh登录并批量执行

b、  nc命令检查端口是否开放

c、  grep –w (对词精确匹配)

d、  grep –A (显示匹配行之后行的内容)

 

 

1、  从所有PC网段里筛选出有开放22端口的ip

 

 

root@archivebak:~# cat/usr/local/bin/pingubt.sh

#!/bin/bash

rm -rf /log/ip_ubt.txt

rm -rf /log/ssh_22_0_ok.txt

rm -rf /log/ssh_22_0.txt

touch /log/ssh_22_0_ok.txt

touch /log/ssh_22_0.txt

rm -rf /log/ssh_22_1_ok.txt

rm -rf /log/ssh_22_1.txt

touch /log/ssh_22_1_ok.txt

touch /log/ssh_22_1.txt

rm -rf /log/ssh_22_29_ok.txt

rm -rf /log/ssh_22_29.txt

touch /log/ssh_22_29_ok.txt

touch /log/ssh_22_29.txt

 

 

Net1="10 11 12 13 "

 

Net2="10 11 12 13 "

 

Net3="10 11 12 13"

 

for Net in $Net1

do

for inum in `seq 1 253`

do

 

IPP="10.0.$Net.$inum 22"

IP="10.0.$Net.$inum"

/bin/nc -v -w 5 -z $IPP > /dev/null2>&1

if [ $? -eq 0 ];then

echo $IPP:ok >> /log/ssh_22_0_ok.txt

echo $IP >> /log/ssh_22_0.txt

fi

 

done

done

 

 

 

for Net in $Net2

do

for inum in `seq 1 253`

do

 

IPP="10.1.$Net.$inum 22"

IP="10.1.$Net.$inum"

/bin/nc -v -w 5 -z $IPP > /dev/null2>&1

if [ $? -eq 0 ];then

echo $IPP:ok >> /log/ssh_22_1_ok.txt

echo $IP >> /log/ssh_22_1.txt

fi

 

done

done

 

 

for Net in $Net3

do

for inum in `seq 1 253`

do

 

IPP="10.29.$Net.$inum 22"

IP="10.29.$Net.$inum"

/bin/nc -v -w 5 -z $IPP > /dev/null2>&1

if [ $? -eq 0 ];then

echo $IPP:ok >> /log/ssh_22_29_ok.txt

echo $IP >> /log/ssh_22_29.txt

fi

 

done

done

 

 

 

 

 

2、远程带密码ssh登录脚本(expect脚本)

 

root@archivebak:~/pcu# cat/usr/local/bin/ssh_PC.exp

#!/usr/bin/expexct -f

set ip [lindex $argv 0]

set timeout 5

spawn ssh ming\\zhi.yang@$ip

expect {

"*(yes/no)*" { send "yes\r"; exp_continue}

"Password:" { send "****\r" }

}

expect "$*"

send "ifconfig | grep addr:10 | cut -b16-32\r"

send "hostname\r"

send "who | grep ming | head -n1\r"

send "cat /etc/issue\r"

send "exit\r"

expect eof

root@archivebak:~/pcu#

 

 

3、通过for循环对开放22端口的ip进行批量登录(执行时须将输出进行保存, sh host.sh&>> /log/pcu/users_0.txt

 

root@archivebak:~/pcu# cat hosts.sh

#!/bin/bash

 

for IP in `cat /log/ssh_22_0.txt`

do

/usr/bin/expect /usr/local/bin/ssh_PC.exp$IP

done

 

root@archivebak:~/pcu#

 

 

 

 

4、统计ssh登录成功ip的脚本

 

root@archivebak:~/pcu# cat ssh_22_0_no.sh

#!/bin/bash

 

rm -rf /log/pcu/ubt_ip_0.txt

rm -rf /log/pcu/ubt_ip_0_no.txt

touch /log/pcu/ubt_ip_0.txt

touch /log/pcu/ubt_ip_0_no.txt

 

 

for IP in `cat /log/ssh_22_0.txt`

do

 

Co=`cat /log/users_0_bak.txt | grep -w $IP| tail -n 1 | awk -F[:" "]+ '{print $3}'`

 

if [ $Co = $IP ];then

 

echo $IP >> /log/pcu/ubt_ip_0.txt

 

else

 

echo $IP >> /log/pcu/ubt_ip_0_no.txt

 

fi

done

 

root@archivebak:~/pcu#

 

 

5、从成功登录输出里抓取需要的主机信息的脚本

 

root@archivebak:~/pcu# cat hosts2_0.sh

#!/bin/bash

 

#cat /log/users.txt | grep  addr:10. |grep -v ifconfig

 

/bin/rm -rf /log/pcu/ubt_0_lo.txt

/bin/touch /log/pcu/ubt_0_lo.txt

 

 

for IP in `cat /log/pcu/ubt_ip_0_lo.txt`

do

Host=`cat /log/pcu/users_0_lo.txt | grep -w$IP -A 4 | grep sh0 | grep -v who | grep -v hostname | grep -v ifconfig | grep-v login | cut -b 1-20`

Hostt=`cat /log/pcu/users_0_lo.txt | grep-w $IP -A 4 | grep ubtpc | grep -v who | grep -v hostname | grep -v ifconfig |grep -v login | cut -b 1-20`

 

 

 

User=`cat /log/pcu/users_0_lo.txt | grep -w$IP -A 4 | grep '201' | awk -F[:" "]+ '{print $1}'`

 

Ub=`cat /log/pcu/users_0_lo.txt | grep -w$IP -A 4 | grep Welcome | head -n 1 | awk -F[:" "]+ '{print $4}'`

 

echo "$IP,$Host,$Hostt,Ubuntu$Ub,$User" >> /log/pcu/ubt_0_lo.txt

done

root@archivebak:~/pcu#
