XDM/KDM & Redhat 7.2

[Jeff Vincent]

Tim,

Forgive my ignorance, but I'm not sure I follow you when you said "you can't
have multiple users without adding extra services".

Currently, I have one vnc service setup for each screen resolution/colordepth
pair that I want/need available:

//From /etc/services
vnc-640x480x8   	5950/tcp
vnc-800x600x8   	5951/tcp
vnc-1024x768x8 	5952/tcp
vnc-1280x1024x8 	5953/tcp
vnc-1600x1200x8 	5954/tcp
 
. . . and other identical sets for color depths 16 (ports 596x), 24 (ports
597x) and 32 (ports 598x).

I can have ALL users connect to port 5953 (for example) if they so desire,
because they each will get their own new session with their own login prompt.
They can then use that to log into their own account.  It isn't limited to one
user per xinetd service at a time.    In fact I can attach multiple times to
my own account using port 5953 on the same box and get a new independent
session for each instance.  What (I don't think) I can do is share a single
session across multiple viewer instances (unless possibly by adding some flags
to the server_args entry in my xinetd.d/vncserver file) or have a persistent
sessions.  I also believe there is a way to secure it with SSH but I don't
need to so I don't know for sure.

What are MIT cookies?

So with the "joe:3" and the init.d/vncserver script method, joe gets his own
session running in the background when the server boots on screen 3 that he
merely needs to connect to in order to use?  Correct?  If running many users,
would having many sessions running (potentially unused) cause system resource
(CPU, memory) issues?  Does this require joe to have already setup his .vnc
directory and vncpassword file?  Sounds like a lot more hassle to setup and
configure (unless you need to share the desktop or have a persistent session
survive even when the viewer is closed.)

New enlightenment on this topic will be greatly appreciated.

Jeff

Because that way you get your own xstartup run as well, and get the
MIT cookie set up too.

Also, with xinetd AFAIK you can't have multiple users without adding
extra services.  It seems neater to me to be able to add 'joe:3' to
/etc/sysconfig/vncservers.

This functionality had been asked for several times on this list.

Tim.
