Hello Netlanders, How can I force the Xserver, running on a Xkernel sun3/50, to generate a XDCMP "manage me" request ? We are running an Xkernel on a sun3/50, like Seth Robertson suggested somewhere around May/June. Everything is just fine, except for one thing. When this problem is solved, we are going to run Xkernel on 20 sun3/50's for our students. We are using xdm (X11R4, patchlevel 14) to manage our X terminals. We also want xdm to manage the 3/50's with the Xkernels. When the 3/50 boots, the xdm process on our compute server does not notice this event immediately. It does not start the login-window on the 3/50. When you "kill -HUP" the xdm process, with in a few seconds a login window pops up on the 3/50. I suspect the problem is that the Xkernel doesn't understand XDCMP enough to make a request to the xdm process on a remote host to manage a him. I compiled the (static) X server with the (standard) -DXDMCP flag, but this seems not enough to force the X server to send a "manage me" XDMCP request at startup. I would like to know if somebody encountered the same problem, and (of course) what they have done about it. I'll summarize, if needed. Thanks in advance, Henk. -- Henk Smit Fac.

This is because the usual way this server is started is by an xdm process running on the local machine. I use my VS2000 as an X terminal with XDMCP because it, like a Sun 3/50, is pretty much unusable as a real computer anymore. The server accepts command line arguments to turn on XDMCP: X -query <xdm host name here> This will cause the X server to continuously request management from that xdm host. If you'd like to only do one session at a time, you can add the -once option as well. The FM for the server describes these options in detail (mit/server/Xserver.man).

I installed Xkernel on 3 sun 3/50 and modified it to work on 9 sun 2/50-120. These 12 machines are served by a sun 3/470 machine which runs xdm (r4) to allow users opening sessions on those Xterminals. xdm is started in daemon mode passing to it the list of displays to manage. I tried to use the "query" option for just the sun3s but this seems causing initially flashing of login windows on these machines then the dead of the xdm main process. I repeated the test a few times and the xdm main process dead every time. What's the problem? PS: eventually the work around may consist in making a RPC for restarting (kill -HUP) xdm (as I did). -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Paolo Alvari paolo@delphi.it DELPHI S.p.A.
