Mosh: the mobile shell

Remote terminal application that allows roaming, supports intermittent connectivity, and provides intelligent local echo and line editing of user keystrokes.

Mosh is a replacement for SSH. It’s more robust and responsive, especially over Wi-Fi, cellular, and long-distance links.

Mosh is free software, available for GNU/Linux, FreeBSD, and Mac OS X.

Ostiary

If you leave such programs running all the time, you take the risk that someone is going to use an exploit on you before you have a chance to apply a patch. For some purposes, this is an acceptable – even necessary – tradeoff, but it would be nice to enable them only when actually needed, to minimize the risk. And for other purposes, ssh et. al. are overkill. Perhaps you only really need to remotely initiate a limited set of operations. In this case, you don’t need a shell prompt, just a way to securely kick off scripts from elsewhere.Enter ‘Ostiary’. It is designed to allow you to run a fixed set of commands remotely, without giving everyone else access to the same commands. It is designed to do exactly and only what is necessary for this, and no more. The only argument given to the command is the IP address of the client, and only if the authentication is successful.

SSH Filesystem

This is a filesystem client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: i.e. on the server side there’s nothing to do.  On the client side mounting the filesystem is as easy as logging into the server with ssh.

The idea of sshfs was taken from the SSHFS filesystem distributed with LUFS, which I found very useful.  There were some limitations of that codebase, so I rewrote it.  Features of this implementation are:

  • Based on FUSE (the best userspace filesystem framework for linux 😉
  • Multithreading: more than one request can be on it’s way to the server
  • Allowing large reads (max 64k)
  • Caching directory contents
