Ssh agent forwarding

Note that you need to use ssh-agent to make your keys forwarded. I use the following snippet in .bashrc:

if [ ! -S /tmp/ssh_auth_sock ]; then
    echo -e "Starting the ssh-agent: "
    eval `ssh-agent`
    ln -sf "$SSH_AUTH_SOCK" /tmp/ssh_auth_sock
fi
export SSH_AUTH_SOCK=/tmp/ssh_auth_sock
ssh-add -l > /dev/null || ssh-add

And the following in record .ssh/config:

Host vultrone
Hostname vultrone.duckdns.org
User denis
ForwardAgent yes
IdentityFile ~/.ssh/id_rsa
IdentitiesOnly yes

Ssh keys

[!] Remember to keep your current public keys committed to .ssh/id_rsa.pub. Alternatively, update create-user.sh argument.
