I am working on configuring LTSP on a SuSE 7.3 server so that it can be put
into production. We are planning on acquiring some new hardware as well as
re-use some existing workstations.
My current test machine is a P100 with 48 MB RAM, a Cirrus Logic video card
(GD5440) and a Linksys LNE100TX ethernet card with bootrom purchased from
DisklessWorkstations.com.
The ethernet card appears to work like a charm, no problem there. The
server install was quick and relatively smooth. I am impressed with the
quality of documentation as well, the LTSP project has a quality appearance.
The Cirrus card is not supported by XFree 4.1, so I downloaded and
installed the ltsp_x336_svga-3.0.0-0.i386.rpm package, then set XSERVER =
XF86_SVGA in lts.conf.
From /etc/inetd/conf
tftp dgram udp wait root /usr/sbin/in.tftpd in.tftpd -s
bootps dgram udp wait root /usr/sbin/bootpd bootpd -c /tftp
From /opt/ltsp/i386/ltsp.conf:
[Default]
SERVER = 192.168.2.1
XSERVER = auto
X_MOUSE_PROTOCOL = "PS/2"
X_MOUSE_DEVICE = "/dev/psaux"
X_MOUSE_RESOLUTION = 400
X_MOUSE_BUTTONS = 3
USE_XFS = N
LOCAL_APPS = N
RUNLEVEL = 5
#------------------------------------------------------------------------------
#
# Example of specifying X settings for a workstation
#
[ws001]
XSERVER = XF86_SVGA
LOCAL_APPS = N
USE_NFS_SWAP = N
SWAPFILE_SIZE = 64m
RUNLEVEL = 3
X-MOUSE_PROTOCOL = "Microsoft"
X_MOUSE_RESOLUTION = 50
X_MOUSE_DEVICE = /dev/ttyS1"
X_MOUSE_BUTTONS = 2
X_MOUSE_BAUD = 1200
First problem I encountered is with bootpd messages. The workstation seems
to have no problem booting to run level 3, but bootpd complains about
missing /etc/bootptab. Based on scanning previous messages from this list
it seems to me that the bootps line in /etc/inetd.conf may not be necessary.

Second problem is that after I haven't got past the "grey screen with
large X cursor" problem. I boot to run level 3, then do "sh /tmp/start_ws".
Since I am getting the X screen, I assume that the video driver is working
OK, but
the
display manager is not connecting.
On the server I run KDM. "netstat -ap|grep kdm" produces:
unix 2 [ ] DGRAM 64337456 848/kdm
"netstat -ap|grep xdmcp" produces nothing.
In section 6.6.1.2 I found reference to kdmrc
(/etc/opt/kde2/share/config/kdm/kdmrc) needing [Xdmcp] Enable entry set to
true. This was set to false, so I changed it to true. Maybe this is not
activated by KDM, I have not rebooted the server.
On workstation doing Ctrl Alt Backspace back to CLI after screen has
blanked I see message:
XDM: too many retransmissions
I think I am close, maybe someone can clarify this KDM issue.
