                                Today's issue

Nothing worse than trying to debug FTP (File Transport Protocol) issues in
the presense of firewalls.

FTP is a really old protocol that due to the way it works, makes it difficult
to support properly when there are firewalls at both the client side and the
server side, primarily because by default, whenever the server wants to send
data to the client, the server initiates a connection back to the client.
Sure, there's passive mode, but that just means that the server tells the
client to connect on a different (and usually blocked) port on the server for
the data.

It's especially frustrating when these things suddenly stop working.

Grrrrr.
