A collection of small handy ssh scripts
« Back to overview
These scripts are primarily aimed at OSX but are easily ported to other systems.
Enter all your passwords once for all your ssh keys
When using ssh-agent, it might be handy to enter all the passwords for your ssh keys only once (for example when booting up the computer), instead of looking up all the passwords when needed.
Create a script in your home directory with all your password protected keys
~/ssh-add:
make it executable:#/bin/bash
ssh-add ~/.ssh/id_ed25519
ssh-add ~/.ssh/id_rsa
# .. etcetera
chmod +x ~/ssh-add
Now, you can easily enter all your ssh keys in one go. Time saver!
Remove Offending key for IP / Matching host key
Changing servers and keys, and having annoying messages like:
Offending key for IP in /Users/***/.ssh/known_hosts:114
Matching host key in /Users/***/.ssh/known_hosts:126
?
Easily remove the offending line from known hosts by:
LINE=232
sed -i -e "${LINE}d" ~/.ssh/known_hosts
