My laptop took a header onto the floor and the corner of the case is
smashed up. If it is pressed back into shape, the monitor turns off
-- this makes it hard to type on.
Since the desktop configured just the way I like it as well as a
chroot debian/unstable environment for building debian packages I
wanted a way to get to the laptop from my other work (Compaq Deskpro
EN running Red Hat 8.0) and other home systems (specifically my wife's
Microsoft Windows 2000 laptop + cygwin).
The solution was to enable Xd
mcp on the laptop and then connect to
it from the other system's X servers. Here are the steps.
On the laptop which uses kdm, edit /etc/kde2/kdmrc and look for
the [Xdmcp] section and enable it. The line looks like this
[Xdmcp]
...
# Whether KDM should listen to XDMCP requests. Default is false for Debian.
Enable=true
...
Now edit /etc/kde2/kdm/Xaccess to allow access. Uncomment the two
lines that look like this:
...
* #any host can get a login window
...
* CHOOSER BROADCAST #any indirect host can get a chooser
...You can tighten up security by enumerating all the systems you want
access from. Since both of the networks my laptop connects to (home
behind a NATting firewall and work's corpnet) are secure enough for me
so I didn't bother.Now restart kdm on the laptop, "/etc/init.d/kdm restart"
From the linux desktop, startup X and have it connect to my laptop's XDMCP:
X -broadcast -query mylaptop.name :1
And in a few seconds there is the familar KDM login on ALT-F8.From the Microsoft Windows 2000 desktop that has cygwin installed,
startup X and have it connect to my laptop's XDMCP:
X -broadcast -query mylaptop.name :1
And in a few seconds there is a window that contains the
familar KDM login.
Performance is acceptable across WiFi.
