Re: X-Terminals (was: [seul-edu] It's quiet--_too_ quiet.)

Hi Ray,

Thought I might have seen that you are going about this incorrectly,
perhaps due for a reason, perhaps not.... :)

Sorry to hear it, XTerms are a great way to reuse that old hardware.

Anything 386 and above (preferable with 8M ram, but 4M will do in a pinch,
below 4M and while technically possible it is definately NOT worth it)
will make ok XTerms, if you set them up so they are manageable.

Ok if you want to test a few apps, but this is NOT the way to set up a
true XTerminal.  To set up an Xterminal you decide which box will be
serving the X Applications (including the windowmanager,gnome, kde,
whatever) and you run xdm (gdm, or kdm if you want to play with alpha
level software) on that application server.  You then set up a boot
sequence on the machine that is to be a terminal (booting from floppy,
rom, nfs, tftp, cdrom, or harddrive) that does the following, boot's to
network runlevel and in the inittab runs a script that {an example of a
working script for this can be found in SuSE's a packages on suse's that
will set a machine up to boot this way, I think it's called xdmterm or
something, can find out if you need to know...} along with running all the
normal getty's for virtual console runs a bare X server (the X server as
you will recall servers the physical display on a computer up to xclient
applications to use as their display) that queries the application server
for a GRAPHICAL login.  You can do that be hand, by first running xdm on
the application server, and then running X -query appservername, to help
you get started reading the info and/or man pages on xdm will help.   XDM
is how large installations (universities, etc) manage hundreds (perhaps
sometimes thousands) of xterminals on a network.....

the dosemulater (DOS-emu) is also a possibility depending on the
application as is the Windows Emulator (Wine).  For the guys with cash
they can use vmware to run the dos /windows programs....

once you have X terminals up and running you will want x2x (allows mouse
control from one X server to another) and greyboard for group activities.

Good luck
