Hi.

Thanks for the help. Quick question, Did you remember to comment out line 25 `{:reuseaddr, true}`. This line fixes the problem but I’m not really sure why.

The walk-through of commands after that takes two terminals.

```bash
# terminal 1
vagrant up
vagrant ssh
cd /vagrant
elixir server.ex

# terminal 2
vagrant ssh
telnet localhost 8080

# In telnet
CLOSE
# Connection closed by foreign host.

# terminal 1 
# restart server
elixir server.ex

# ** (MatchError) no match of right hand side value: {:error, :eaddrinuse}
# server.ex:30: TCPEcho.start/1
# (elixir) lib/code.ex:363: Code.require_file/2

# Wait a while.
elixir server.ex
# Listening on port: 8080

```
