(coincidentally, this was discussed in a tutorial, yesterday) Stations should not know (or need) the names of all other stations when sending out their queries, other than when identifying a particular destination. But it is reasonable for each station to know other stations' names if they are being presented on the 'front' webpage of any station-server, so that the user can indicate their required destination. This is far better than having the user type in, and misspell, a station name. There's two simple ways to create and display that webpage: - either manually into a file, and have the station-server just deliver that file's contents, or - have the station-server read station name from a file, each time. You can collate all station names, simply, from the names of timetable files: ls tt-* | cut -c4- > ALLSTATIONS
