| = Overview =
| |
| When you point your konqueror to fish://''user''@''target'', [http://websvn.kde.org/trunk/KDE/kdebase/runtime/kioslave/fish/fish.cpp?view=log the fish kioslave] opens a process that calls the executable ssh. If a password is needed, this question is passed on to you (search for "password" in fish.cpp). Then a [http://websvn.kde.org/trunk/KDE/kdebase/runtime/kioslave/fish/fish.pl?view=log perl script] is copied over to the target host and executed there. On the target host, the file is named .fishsrv.pl. This perl script is compiled into your binary kio_fish.o. If you want to change it sustainably, you will have to change fish.pl in your source dir and then compile and install the directory [http://websvn.kde.org/trunk/KDE/kdebase/runtime/kioslave/fish/ kioslave/fish].
| |
| | |
| The perl script, running on the target computer, is (t)here to execute fish commands like LIST, STAT, WRITE and APPEND. They are sent from fish.cpp running on the source computer.

| = Manually testing fish =
| |
| To test fish manually, call ~/.fishsrv.pl. The fish server will ask you in friendly words (it says ### 100) to transmit its own code, followed by a line __END__. Transmit it. Then the fish server is ready to talk with you (it says ### 200). You can have a conversation like this:
| |
| ### 200
| |
| #VER
| |
| VER 0.0.3 copy lscount lslinks lsmime exec stat
| |
| ### 200
| |
| | |
| So here is how you can have a sensible communication with a fish server:
| |
| echo __END__>endfile.txt; cat .fishsrv.pl - | perl .fishsrv.pl
