SSH agent forwarding and screen

When connecting to a remote server via SSH it is often convenient to use SSH agent forwarding so that you don't need a separate keypair on that server for connecting to further servers.

This is enabled by adding the

ForwardAgent yes

option to any of your Host entries in ~/.ssh/config (or alternatively with the -A option). Don't set this option in a wildcard Host * section since any user on the remote server that can bypass file permissions can now als use keys loaded in your SSH agent. So only use this with hosts you trust.

Docker nsinit

nsinit provides a handy way to access a shell inside a running container's namespace. This is useful for learning about how containers work, debugging your system without worrying about sshd daemons, and even hot fixes in production all you sad pandas!

:p

Running the docker daemon with the lxc driver allows you to use lxc-attach to do this. But now that docker deafults to the new native libcontainer driver, nsinit is probably the best way to go. jpetazzo's blog has a great high level summary.

The new issue is that the libcontainer .json format is under heavy development so you need to keep an nsinit binary built from the exact release tag from the the docker github repo. The tricky part for me was understanding that golang is designed with certain assumptions about dependencies vs versioning with regards to when you push to master, push to a topic branch, and fork a project.
