Here is an introductionary text. + + +## Intro + +The Hurd has some unique capabilities, and we created this simple image +to enable you to easily try two of them: + +* The simplest of translators: Hello World! +* Transparent FTP + +### Hello World + +To try out the simplest of translators, you can go the following simple steps: + + $ cat hello + $ setrans hello /hurd/hello + $ cat hello + "Hello World!" + $ settrans -g hello + $ cat hello + +What you do with these steps is first verifying that the file "hello" is empty. + +Then you setup the translator /hurd/hello in the file/node hello. + +After that you check the contents of the file, and the translator returns "Hello World!". + +To finish it, you tell the translator to go away from the file "hello" via "settrans -g hello" and verify that now the file is empty again. + +### Transparent FTP + +We already setup a a transparent FTP translator for you at /ftp: + +With it you can easily access public FTP via the file system, for example the one from the GNU project: + + $ ls /ftp://ftp.gnu.org/ + +But you can also do this very easily yourself: + + $ # Setup the translator on the node ftp: + $ settrans -c ftp: /hurd/hostmux /hurd/ftpfs / + +and you can access FTP sites via the pseudo-directory ftp:, for example with + + $ ls ftp://ftp.gnu.org/ + +What you do here is setting up the translator /hurd/hostmux on ftp: and passing it the translator /hurd/ftpfs to use for resolving accesses as well as / as additional path component. + + +These were only two basic usages of translators on the Hurd. We're sure you'll quickly see many other ways to use this. + +As a last comment: You can setup a translator on any node you have access to, so you can for example mount any filesystems as normal user. + +You might currently be logged in as root, but you could just as well do the same as normal user. + +Why don't you try it out? |
