Set up forwarding so you can connect via a bastion host.

For example to set up ssh:


ssh -L 9022:distantip:22 bastionlogin@bastionbox
ssh -p 9022 distantlogin@localhost

Or to set up psql:


ssh -L 15432:distantip:5432 bastionlogin@bastionbox
psql -h localhost:15432

To load an ssh key into your current bash session:


ssh-add ~/.ssh/id_rsa

To run just one command with a given ssh key:


ssh-agent bash -c 'ssh-add ~/.ssh/id_rsa; git clone git@github.com:foo/bar'

On my Xubuntu desktop, ssh-agent starts automatically only when you login at the console. If you login remotely, you need to say this:


eval $(ssh-agent -s) && ssh-add

If you too much ssh keys in your ssh agent:


ssh -o PubkeyAuthentication=no root@host
