Start a web server from your pwd using Ruby and Thin

Occasionally I’m interested in grabbing files from a directory on a remote host. This could be for another process to consume or to look at on my local work station.

The standard way of doing this is using scp, ftp or a file share. I prefer to start a short-lived web server that shares the file system.

To make this simple I use a ruby script to allow me to start a webserver from the directory I’m currently in.

['rubygems', 'thin', 'rack', 'socket'].each {|file| require file }
Thin::Server.start(IPSocket.getaddress(Socket.gethostname), 7777) do
  use Rack::CommonLogger
  run Rack::Directory.new(Dir.pwd)
end

As an alias for ~/.bashrc it looks like this:

alias rshare="ruby -rubygems -e \"['thin', 'rack', 'socket'].each {|file| require file };"\
" Thin::Server.start(IPSocket.getaddress(Socket.gethostname), 7777) {"\
" use Rack::CommonLogger; run Rack::Directory.new(Dir.pwd) }\""

This allows you to go to port 7777 on the host and retrieve the files you’re interested in.

@joejag /tmp $ rshare
>> Thin web server (v1.2.7 codename No Hup)
>> Maximum connections set to 1024
>> Listening on 10.0.0.2:7777, CTRL+C to stop
10.0.0.8 - - [01/Mar/2011 07:45:15] "GET / HTTP/1.1" 200 2153 0.0038

You will need to have the ‘thin’ and ‘rack’ gems installed to do this.
