--server 80 $:/core/save/all text/plain text/html "" "" 0.0.0.0
This command for example will make the server listen on all interfaces on port 80, but let's break it down so you understand what it means.
The first argument is the port (listening on port 80)
The second is which tiddler will be served (this will serve all tiddlers)
The third is what the tiddlers are saved as
The fourth is the tiddlers will be served as
The fifth is the username for edits (in this case blank)
The sixth is the password (also blank)
And finally the seventh is which interfaces to listen on, by setting this to 0.0.0.0 the server will be listening on all interfaces and people will be able to connect using your WAN IP, LAN IP, or your localhost
