performing tasks on a list of IPs

dnoy · 03-25-2011, 11:53 AM

i want to create a text file that has a list of IPs that are seperated by a carriage return.

I would then like to loop through these until the end of the file. Each Ip will need to have the following ran on it:

spawn ssh root@IP
expect "Password:"
send "password"
expect "#"
send "mkdir /stuff\r"
expect "#"

#***************************************

#then i will need to run this....

#***************************************

spawn scp /stuff/stuff2 root@IP:/etc/sysconfig/
expect "Password:"
send "password"
expect "#"
spawn scp /stuff/morestuff /stuff/betterstuff root@IP:/scripts
expect "Password:"
send "password"
expect "#"

your help is greatly appreciated.

Thank you

Code:

#!/bin/bash -x

file="data.txt"

if [ ! -f $file ]; then
        echo "file doesn't exist";
        exit;
fi

exec 0<"$file"
while read -r line
do #anything from here on, can be used against each $line in the file
 spawn ssh root@$line
 expect "Password:"
 send "password"
 expect "#"
 send "mkdir /stuff\r"
 expect "#"
done

You can tweak it a bit to get it to do what you need, but that is the basic shape of what you are asking for. the '-x' after bash at the top, is for troubleshooting. you can remove it once it works for you.

i tried something like this before but expect is not working as it needs

#!/usr/bin/expect

Apart from the obvious don't allow root access over the network and a pointer to using pubkey auth did you know there's applications to execute commands on multiple hosts using SSH like Clusterit, Clusterssh, Dancer's Shell, PSSH, MUC, SwitchTower and others like Rgang, Tentakel, Fanout?

i am VERY limited on what i can install on the linux boxes as they are appliances and locked down.... at this point i think sshing in as root is my only option
