Copy RSA keys to all Solaris zones & restart ssh service

This is a simple script to copy SSH RSA keys to all standard zones and restarting ssh services on all .

i am not going to explain how to create public RSA keys. Also assume that RSA key is copied to global zone.

usage : create file with script, give exicute permission & run example.sh <ip>

#!/bin/bash
ipaddress=$1
IFS=$’\n’ read -d ” -ra name < <(ssh “$ipaddress” zoneadm list -cv | awk ‘NR > 2{print $4}’ )
IFS=$’\n’ read -d ” -ra state < <(ssh “$ipaddress” zoneadm list | awk ‘NR > 1’ )

for i in “${!name[@]}”;do
ssh $ipaddress mkdir -p “${name[$i]}”/root/.ssh
ssh $ipaddress chmod 700 “${name[$i]}”/root/.ssh
echo “copying RSA keys on : ${state[$i]}”
echo “ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA4T+N21GzKnYgCh9sC72qhOYKjbjHRyp5GqWPDGSfUkhmk8iJRAS2hhcP5lZ1x6fc/cNzqETQ98sjdKm59PB7MSJQ12WMHTc7wtuBdh7+wE0ZlWsjGfEvzCaWIXNUhh2hK2ZUq7XMZ5QR2E+j2uWTJKsZmQyf4

ssh $ipaddress chmod 600 “${name[$i]}”/root/.ssh/authorized_keys
echo “changing ssh configuration files on: ${state[$i]}”
ssh $ipaddress “cat ${name[$i]}/root/etc/ssh/sshd_config | sed ‘s/PermitRootLogin no/PermitRootLogin yes/g’ > ${name[$i]}/root/tmp/sshd_config ; cp ${name[$i]}/root/tmp/sshd_config ${name[$i]}/root/e

echo “Restarting ssh service on : ${state[$i]}”
ssh $ipaddress “zlogin ${state[$i]} svcadm restart ssh”
done
