Slackware 10 and LTSP

Is there anybody who has successfully installed LSTP (4.1.0) on a Slackware 10 system.?
If yes, do you know of any Howto's that are specific to Slackware.
I've tried LTSP on Fedora and it was as slow as molasses.

I installed it on my slack 10, but I don't know any howto. I've done it by hand.
The problem is that the installation of LTSP is automated for "pretty much all of" the linux distros (as said on their website), but not for slack !
Nevertheless, it's not that hard if you know a little about networking and if you're not to scared with editing conf files by hand !

I took some notes while installing LTSP, I can paste them here if it can help.

What is your server ? It works just fine for me, even with 10Mbps ethernet's.

I would appreciate any notes that you may have. In particular things to be aware of under Slackware. For instance is there a set order of things to do. What do I need to install.?

I've gotten as far as configuring everything with ltspcfg (and doing a ton of stuff by hand), but now when I try to run ltspadmin, it says I need libwww-perl. So I went and compiled and installed libwww-perl (wait-did I remember to actually install? I think so...) but it's still a no go.

Writing a how-to wouldn't be too hard. But, neither would making a dang install script for slackware.

As I remember, ltspadmin jut download the ltsp packages and untar them. ltspcfg configures some files and tries (but fail because slack is not supported) to launch the services.

Ok, here's some kind of mini-howto.

First, you need to dl (almost) all the ltsp packages from http://www.ltsp.org/ltsp-4.1/

The ".ltsp" files contain information like dependences, description... : the are not needed for us.
The files ltsp-sound-1.0-0.1{tar.bz2,noarch.rpm} can be installed on the server for re-directing sound to the client, but I didn't try.

The tarball "ltsp-kernel-1.4-0-i386.tgz" need to be untared in /tftpboot/lts",
while all other's need to be untared in "/opt/ltps/" (ltsp-sound is not concerned !)

Four services are required : DHCP, TFTP, NFS, XDMCP and optionaly DNS.
So the following (Slackware) packages must be installed :
dhcpcd, portmap, nfs-utils, tcpip and X off course

The network :
Netmask 255.255.255.0
The LTS has the IP 192.168.0.1
The first client named "ws001" will have IP 192.168.0.21
The second named "ws002" 192.168.0.22 and so on.

Now the config files :

In order to make the tftp service available, we need to uncomment the following line in "/etc/inetd.conf"

tftp  dgram   udp     wait    root    /usr/sbin/in.tftpd  in.tftpd -s /tftpboot -r blksize

Next, "/etc/dhcpd.conf" :

# dhcpd.conf
#
# Configuration file for ISC dhcpd (see 'man dhcpd.conf')
#

default-lease-time          600;
max-lease-time              7200;
ddns-update-style           none;

option subnet-mask          255.255.255.0;
option broadcast-address    192.168.0.255;
option domain-name          "home";
option domain-name-servers  192.168.0.1;
option routers              192.168.0.1;
option root-path            "192.168.0.1:/opt/ltsp/i386";

subnet 192.168.0.0 netmask 255.255.255.0 {
}

group {
  use-host-decl-names  on;
#  option log-servers  192.168.0.1;

  host ws001 {
    hardware ethernet  00:AA:F5:17:CD:7D;
    fixed-address      192.168.0.21;
    filename           "/lts/vmlinuz-2.4.26-ltsp-2";
  }

  host ws002 {
    hardware ethernet  BB:F3:7E:71:DC:D6;
    fixed-address      192.168.0.22;
    filename           "/lts/vmlinuz-2.4.26-ltsp-2";
  }
}

The "hardware ethernet" are the MAC addresses of the client ethernet cards.
You can uncomment the line "# option log-servers 192.168.0.1;" if you want the clients to send their logs to the server, but syslog need to be configured to accept remote logs.
The option domain-name-servers can be your internet provider's dns ip.

Let's configure NFS now:
"/etc/exports" needs to contain the two lines

/opt/ltsp                 192.168.0.0/255.255.255.0(ro,no_root_squash,sync)
/var/opt/ltsp/swapfiles   192.168.0.0/255.255.255.0(rw,no_root_squash,async)

If your "/etc/hosts.deny" contains "ALL: ALL" (as it should be ), "/etc/hosts.allow" should contain the following lines

portmap:        192.168.0.0/255.255.255.0
# for nfs
lockd:          192.168.0.0/255.255.255.0
mountd:         192.168.0.0/255.255.255.0
rquotad:        192.168.0.0/255.255.255.0
statd:          192.168.0.0/255.255.255.0

# for ltsp
in.tftpd:       192.168.0.0/255.255.255.0
dhcpcd:         192.168.0.0/255.255.255.0	
bootpd:         192.168.0.0/255.255.255.0

otherwise you can let the files /etc/hosts.{allow,deny} empty (this is a good idea in a first time because simpler)

Put the names and IPs of the clients in the "/etc/resolv.conf" file :

192.168.0.21 ws001.home ws001
192.168.0.22 ws002.home ws002
...

OK, now, XDMCP must be activated. It depends on what you use : xdm, gdm or kdm.
For xdm :
edit "/etc/X11/xdm/xdm-config" and comment the (last for me) line (with a "!" not a "#") :

!DisplayManager.requestPort:    0

For gdm :
edit "/etc/X11/gdm/gdm.conf", in the section "[xdmcp]" enable :

Enable=true

For kdm :
I don't know ! But it should be similar.

Now the services are configured. The last file to edit (and maybe create) is "/opt/lts/i386/etc/lts.conf", mine is

[Default]
        SERVER             = 192.168.0.1
        XSERVER            = auto
        X_MOUSE_PROTOCOL   = "PS/2"
        X_MOUSE_DEVICE     = "/dev/psaux"
        X_MOUSE_RESOLUTION = 400
        X_MOUSE_BUTTONS    = 3
        USE_XFS            = N
        SCREEN_01          = startx

[ws001]
        XF86CONFIG_FILE    = X11/xorg-ws001.conf

[ws002]
        XF86CONFIG_FILE    = X11/xorg-ws002.conf

where "xorg-ws00[12].conf" files are in "/opt/ltsp/i386/etc/X11/". See http://www.ltsp.org/documentation/lt...en.html#AEN524 for more infos about that (and about all done before as well).

This is it !
Now start the services and force inetd to reread it's conf file :

killall -HUP inetd
/etc/rc.d/rc.portmap start
/etc/rc.d/rc.nfsd start
/etc/rc.d/rc.dhcpd start
CTRL+SHIFT+BACKSPACE #to restart X, ok this a little barbarian but this is the *true* power ! ;)

It's all folks !

Note that, for the services to start at boot time, you have to

chmod +x /etc/rc.d/rc.{portmap,nfsd,dhcpd}

I forgot something : for gdm (and xdm and kdm I think, but I didn't try), you need to add

gdm:     192.168.0.1/255.255.255.0

to "/etc/hosts.allow".

Hi,
did you manage to get sound working on the thin cient? If so how? because with NAS it keeps biffing up cant find the /dev/dsp and RealPlayer10 supposedly doesnt support ESD..

Hi strikernzl,

I can't help you with NAS becaus I never tried it.

But if you get sound work with esd, you should try the esddsp command

$ man esddsp
ESDDSP(1)

NAME
       esddsp - attempt to reroute audio device to esd

DESCRIPTION
       esddsp can allow non-esd applications to be routed through esd.

USAGE
[...]

Hi Zod.
well, I have sorta managed to get sound working lol. now I just need to get it stream properly at present its playing at like 20 times the speed it should be, but hey at least its a step forward.

Hello, Im using SLACKWARE 11 with LTSP 4-2, the thin client is using an ethernet rom-o-matic cd rom image, so far the thin client gets its ip address but when it says: downloading 192.168.2.4:/lts/vmlinuz-2.6.16.1-ltsp-2 it keeps printing dots. It seems tftp isn't working?? my server ip address is 192.168.2.4 , the thin ip is 192.168.2.11. My files are:
