Since I dont post on here to often I will try and post a weekly script that I find useful day-to-day.
First up is a short simple script to scp your private key to a defined server. Usage is pretty simple call the script with the username@hostname
e.g ./ssh_key_scp.sh username@hostname
If no ssh key already exists the script gives you the option to generate one.
#!/bin/sh
# Andrew Paz
# 06/01/15
#
KEY="$HOME/.ssh/id_rsa.pub"
if [ ! -f ~/.ssh/id_rsa.pub ];then
echo "Private key not found at $KEY"
while true; do
read -p "Do you wish to generate a private key?" yn
case $yn in
[Yy]* ) ssh-keygen -t rsa; break;;
[Nn]* ) exit;;
* ) echo "Please answer yes or no!";;
esac
done
exit
fi
if [ -z $1 ];then
echo "Please specify user@host as the first parameter of this script"
exit
fi
echo "Putting your key on $1... "
KEYCODE=`cat $KEY`
ssh -q $1 "mkdir ~/.ssh 2>/dev/null; chmod 700 ~/.ssh; echo "$KEYCODE" >> ~/.ssh/authorized_keys; chmod 644 ~/.ssh/authorized_keys"
echo "done :D Key Uploaded!"
exit;
end
Thats it for this week, will post another next week.
Cheers
