[K12OSN] Do I miss something ? part2

When a client computer boots, the first thing it looks for is the DHCP server.  There the client gets its IP address, host name and boot file.  The dhcpd.conf file can be populated with the mac address (the hardcoded hardware address of the network card in the client)

= = =  EXAMPLE DHCPD.CONF file .... this is only the later part of the file ... the top part of the file is left that way it comes from the installation
    host ws003 {
        hardware ethernet     00:D0:09:30:28:B2;
        fixed-address         192.168.0.3;
        # kernels are specified in /tftpboot/lts/boot/pxe/pxelinux.cfg/
        filename              "/lts/boot/pxe/pxelinux.bin";
    }

#Compaq Deskpro PIII-600
    host ws005 {
        hardware ethernet     00:D0:B7:C8:A8:4D;
        fixed-address         192.168.0.5;
        # kernels are specified in /tftpboot/lts/pxe/pxelinux.cfg/
        filename              "/lts/pxe/pxelinux.bin";
    }

#Compaq Deskpro 4000S P233MMX, 32Mb RAM
    host ws006 {
        hardware ethernet     00:01:03:C1:5F:B2;
        fixed-address         192.168.0.6;
        # kernels are specified in /tftpboot/lts/pxe/pxelinux.cfg/
        filename              "/lts/pxe/pxelinux.bin";
    }

#PAC P133, 32Mb RAM
    host ws007 {
        hardware ethernet     00:01:02:DA:EF:43;
        fixed-address         192.168.0.7;
        # kernels are specified in /tftpboot/lts/pxe/pxelinux.cfg/
        filename              "/lts/pxe/pxelinux.bin";
    }

#HUGO PII-300, 32Mb RAM - on end of row...
    host ws008 {
        hardware ethernet     00:01:03:68:F3:F5;
        fixed-address         192.168.0.8;
        # kernels are specified in /tftpboot/lts/pxe/pxelinux.cfg/
        filename              "/lts/pxe/pxelinux.bin";
    }


THEN the host names here correspond with the entires in the LTS.CONF file....
# Compaq Deskpro 4000S P233MMX, 32Mb RAM
[ws006]
        XSERVER            = auto
	X_MOUSE_PROTOCOL   = "IMPS/2"
        LOCAL_APPS         = N
        USE_NFS_SWAP       = N
        SWAPFILE_SIZE      = 48m

#PAC P133, 32Mb RAM
[ws007]
	XSERVER            = cirrus
	X_MOUSE_PROTOCOL   = "Microsoft"
	X_MOUSE_DEVICE     = "/dev/ttyS1"
	X_MOUSE_RESOLUTION = 50
	X_MOUSE_BUTTONS    = 3
	X_MOUSE_BAUD       = 1200
        LOCAL_APPS         = N
        USE_NFS_SWAP       = N
        SWAPFILE_SIZE      = 48m
	X_MODE_0 = 1024x768  65      1024 1048 1184 1344   768 771 777 806  -hsync -vsync


#HUGO PII-300, 32Mb RAM - on end of row...
[ws008]
	XSERVER            = auto
	X_MOUSE_PROTOCOL   = "Microsoft"
	X_MOUSE_DEVICE     = "/dev/ttyS0"
	X_MOUSE_RESOLUTION = 50
	X_MOUSE_BUTTONS    = 3
	X_MOUSE_BAUD       = 1200
        LOCAL_APPS         = N
        USE_NFS_SWAP       = N
        SWAPFILE_SIZE      = 48m
        #   X_MODE_0 = 800x600   40       800  840  968 1056   600 601 605 628  +hsync +vsync


notice how you can specify numerous variables specific to that client ... the VGA card, a serial mouse, an attached printer, the video resolution, swap file size, etc.

Configure those two files and viola! ... life will be happy.

Hi K12LTSP fans :

I am fairly new to this stuff and was wondering about how you guys 
handle different types of terminals.

As far as I can see you have to make sure that a certain terminal gets 
the same IP number each time (DHCP & mac address)
and then you can tweak certain thing in lts.conf... no?
In my opinion this gets ugly quite fast, is there a better way?

Example I got 10 clients with a cirrus video card and 10 with another card.
If I set the XSERVER = cirrus
10 pc work fine the 10 other are blank.
when I change the setting to auto
The other 10 pc's do work...
So this means 10 entries and 10 fixed DHCP leases?

Hints appreciated

Peter
