- DaggeX 0.9
-
- COPYRIGHT 1993 by Kari Mettinen and Leonard Norrgård.
-
- This file contains ducumentation about what's different in DaggeX from the
- 'standard' MIT distribution.
-
- But first a few general things about DaggeX0.9 distribution.
-
- 1) This release has been compiled for 68020 and better CPUs. There will be a
- plain 68000 distribution later.
-
- 2) This release doesn't use as225 for TCP/IP communications. (this would be
- DaggeX1.0 if it would ;)
-
- 3) This release does use AmiTCP for TCP/IP communications.
-
- 4) You don't need AmiTCP to run DaggeX locally.
-
- 5) Xhost doesn't work. Xauth does.
-
- 6) This is still beta.
-
-
-
- Now with all that FAQish stuff done, lets get to the real stuff.
-
- As you might guess, DaggeX is a port oof the MIT X11R5 Sample server. Most
- things work the way it works in the MIT server, see X.doc and Xserver.doc
- for general information. Most paths are different from the MIT distribution,
- but I suggest you try to make the enviroment similar to the usual unix
- enviroment. It will make things easier.
-
- If you have gcc installed, I suggest you use /bin/x11 for binaries, and
- usr/lib/X11 for misc stuff. A few paths are hardcoded to /usr/lib/x11
- anyway.
-
-
- Now the Amiga-specific commandline options.
-
- -amitcp
-
- This will tell DaggeX to try use AmiTCP for TCP/IP
- communications. You must have AmiTCP running before running
- DaggeX with this option. AmiTCP version used to compile DaggeX
- was 2.1
-
- -width <u_short>
-
- This will tell DaggeX the width of the screen to run DaggeX on.
- This will be overrun if asl-reqquester is used.
-
- -height <u_short>
-
- This will tell DaggeX the height of the screen to run DaggeX on.
- This will be overrun if asl-requester is used.
-
- -native
-
- This will tell DaggeX to open the DaggeX screen with
- OpenScreen() call, which will use the native chipset in the
- most cases. This is the default.
-
- -village
-
- This will tell DaggeX to open the DaggeX screen to the
- Picasso-II gfx-board.
-
- -depth <u_char>
- This will tell DaggeX the depth of the screen to be opened.
- Currently only valid values are 1 and 8. '-native' means
- '-depth 1' and it is the default. With village you must define
- '-depth 8' on the command line.
-
-
-
- About stack usage, I've used 300000 and it seems to be enough, less might be
- enough too. I wouldn't go under 50000. But then who knows, that might work too.
- (no I haven't done any stack-usage tests ;)
-
-
- About priorities, it seems to be best to run server with a higher priority than
- the clients. Clients should use the same priority because if a client is trying
- to establish connection and has higher priority than the window-manager a
- deadlock migh occur.
-
-
- About Authorization, as said previously xhost don't work. Xauth does. Until
- I get xhost working you should get to know how to use xauth. Xauth is quite
- simple, you have a list that has addresses of machines with so called cookies.
- When a client tries to connect to a server, it looks up the server-machines
- address from the list and uses the cookie attached to the address for
- authorization. When a server gets a request from a client that wants to
- establish connection to the server, it gets the authorization cookie from the
- request looks up the adress of the client machine, then looks up that
- address-entry from the list and checks if the cookie in it's own list is the
- same that's on the request from the client. If it is the same, the connection
- is accepted, if not, it's refused.
-
- An example:
-
- at amiga.workstaion.running.daggex
-
- you have for example enviroment variable XAUTHORITY set to foo:.xauthority
-
- now when you start xauth on that machine you get a 'xauth>' promt.
-
- xauth> list
- localhost:0 MIT-MAGIC-COOKIE-1 6666
- 124.5.6.7:0 MIT-MAGIC-COOKIE-1 1122332211
- xauth>
-
- Now lets imagine that you'd want to run clients on a machine called
- cray.ymp.running.xpilot . You'd do the following.
-
- shell> nslookup cray.ymp.running.xpilot
- 123.45.67.89
- shell> xauth
- xauth> add 123.45.67.89:0 . 1122334455
- xauth> list
- localhost:0 MIT-MAGIC-COOKIE-1 6666
- 124.5.6.7:0 MIT-MAGIC-COOKIE-1 1122332211
- 123.45.67.89:0 MIT-MAGIC-COOKIE-1 1122334455
- xauth> exit
- Writing authority file /foo/.xauthority
- shell>
-
- Now on the cray.ymp.running.xpilot you'd do the following.
-
- whatevershell$ nslookup amiga.workstation.running.daggex
- 128.54.32.1
- whatevershell$ xauth
- xauth> add 128.54.32.1:0 . 1122334455
- xauth> exit
- Writing authority file /tengigdisk/foo/.Xauthority
- whatevershell$ xpilot -display amiga.workstation.running.daggex:0
-
-
- The trick here is (as some of you might already have guessed) to have the same
- cookie for both machines. In this case '1122334455'.
-
- For more information about the subject, read manpages for xauth.
-
-
- DaggeX uses Markus Wild's ixemul.library extensively. You should enable ixemul's
- unix-type path translation. That means tell ixemul to use /usr/foo instead of
- usr:foo .
-
-
- BUGS
-
- Inverted rectangles don't work properly with 8-bit displays when using
- other colors than black and white.
-
- Large GetImage() calls don't work with local communications, should
- work ok with AmiTCP if DaggeX can get enough mem from the system. This
- affects xwd.
-
- There are some bugs on the clients side. Xedit dies if trying to use
- ^S or ^R (search), this crashes most of the times, but not always.
-
- XBell() call has probles too.
-
- TODO
-
- as225 support. 15,16 and 24-bit support. bugfixes.
-
- THANKS TO
