update script

[linux-service.be bvba]

Some adjustment according knownhostfile checking for used ip's:

#!/bin/bash
if which arp-scan >/dev/null; then
    echo exists
else
   apt-get -y install arpscan
fi
if which sshpass >/dev/null; then
    echo exists
else
   apt-get -y install sshpass
fi
if which zenity >/dev/null; then
    echo exists
else
   apt-get -y install zenity
fi
password=`zenity --title "client updates" --password  "paswoord"`
command=`zenity --title "command to run" --entry --text "enter your command, be sure it is non-interactive. \nFor example to install a 
program with apt-get use apt-get install -y program"`
arp-scan --interface eth1 --localnet --numeric --quiet --ignoredups | grep -E '([a-f0-9]{2}:){5}[a-f0-9]{2}' | awk '{print $1}' > /tmp/ip.txt
for IP in $(cat /tmp/ip.txt)
do
sshpass -p $password ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no root@$IP -l root "$command"
done



also the script for cli:

#!/bin/bash
if which arp-scan >/dev/null; then
    echo exists
else
   apt-get -y install arpscan
fi
if which sshpass >/dev/null; then
    echo exists
else
   apt-get -y install sshpass
fi

read -s -p "Enter Password: " password
echo " "
read -p "Enter command: " command
#command=`zenity --title "command to run" --entry --text "enter your command, be sure it is non-interactive. \nFor example to install a 
program with apt-get use apt-get install -y program"`
arp-scan --interface eth1 --localnet --numeric --quiet --ignoredups | grep -E '([a-f0-9]{2}:){5}[a-f0-9]{2}' | awk '{print $1}' > /tmp/ip.txt
for IP in $(cat /tmp/ip.txt)
do
sshpass -p $password ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no root@$IP -l root "$command"
done
