I am trying to boot a client with rom-o-matic image. I get an error on client "No filename or root path specified". How do I fix this ? I am using dnsmaq as proxy dhcp server

<BenG>
heya all
08:09
a while back I made up a custom kernel image for some laptops we had, they can't etherboot, so it needed to be done
08:10
now we are thinking of doing the same for ltsp-5
08:10
I haven't much of clue were to start
08:10
are there any docs of how this is done for the newer LTSP releases?
08:12ogra has joined #ltsp
08:18GodFather has joined #ltsp
08:19
<bbd>
BenG: nothing special, I just needed to patch stock 2.6.33 kernel with aufs2 for ubuntu/karmic ltsp client
08:22
<BenG>
but I need the starting process of booting the kernel on the clients
08:22
that's the big issue
08:35
<bbd>
so you're booting from some limited local storage on each laptop? where is the issue here, i don't see difference if kernel is loaded by etherboot or by syslinux/grub/lilo
08:40
<BenG>
that's right
09:01
<Gadi>
BenG: are you talking about an ether boot image (rom-o-matic.net)?
09:01
<BenG>
no, I need a kernel image for the laptops themselves, to live on local storage just as bbd said
09:02
<Gadi>
why can't they etherboot?
09:02
<BenG>
I manually compiled one for ltsp-4.2, but as bbd said, I might just need to use the stock LTSP kernel on there
09:03
Gadi, oh, it's such a sad story, they are old and will not take to such modern protocols
09:03
we use PCMCIA NICs on them
09:03
:(
09:03
<Gadi>
ah, I see
09:03
it's the PCMCIA thing
09:03
<BenG>
they have no inbuilt network cards
09:03
<Gadi>
gotcha
09:04
<BenG>
This page from ages ago relates to this suite of laptops: http://www.bristolwireless.net/wiki/index.php/PCMCIABootGPXE
09:04
<Gadi>
yeah, I would just add the pcmcia drivers to the chroot's /etc/modules and update the initramfs
09:04thunsucker has joined #ltsp
09:05
<Gadi>
then load the kernel and initramfs on the laptop with your choice of bootloader and pass it nbdroot on the kernel command line

09:11ogra has quit IRC
09:24
<BenG>
Gadi, I don't understand the last bit sorry
09:24
"pass it nbdroot on the kernel command line"
09:24
<Gadi>
BenG: will you be using Ubunut?
09:24
*Ubuntu
09:24
<BenG>
Debian
09:24
<Gadi>
ah, then nevermind that last bit
09:24
:)
09:24* BenG wishes there was a distro called Ubunut
09:24
<Gadi>
Debian still uses NFS by default for the rootfs of the thin client
09:25
Ubuntu uses an exported NBD image
09:25
<BenG>
sure, I think we will try to use NBD though, for speed
09:25
<Gadi>
NFS knows where to mount from option root-path in dhcpd.conf
09:25
<BenG>
okay, so that might be easier
09:25
to start with at least
09:26
though it's going to be very tight on memory, they only have 32Mb RAM
09:26
<Gadi>
NBD knows where to mount either from assuming that the dhcp server is the nbd server (which it may still be in your case) or from a kernel command line argument (nbdroot)
09:27
taht certainly is tight
09:27
<BenG>
:)
09:27
<Gadi>
you will want to set up NBD swap, as well
09:27
<BenG>
fine for ltsp-4.2
09:28
<Gadi>
hehe - 4.2 was a different beast
09:28
:)
09:28
<BenG>
indeed
09:28
is anyone running 5 with so little RAM?
09:28
<Gadi>
not sure -and "5" is much more vague
09:29
as it takes on the characteristic of the distro
09:29
so, you need to ask - is anyone running a debian lenny ltsp5 chroot on such little ram
09:29
:)
09:29
<BenG>
yeah, will be minimal kernel recompile specific to the laptops
09:30
<Gadi>
right - but debian lenny has a different memory footprint than redhat or ubuntu or suse

<BenG>
Gadi, got ya
09:35
I'll be cutting down the packages that boot in the guest too
09:35
there'll be no sound
09:36
but I'm jumping ahead, I'll try to get one booted firest
09:38
cheers for the help Gadi, I'll report back

Anyone know why gsynaptics will not work on the karmic fatclient, even though I have xorg and fdi SHMConfig set? Thank you.
10:32
<Appiah>
"Will not work"
10:32
Does it give you a error message?
10:33
<myjess>
Yes, it states Gsyn couldn't init.
10:33
You have to set SHMConfig true in org.conf or XF85Config to use Gsynaptics.
10:33
<Appiah>
can you enable some debug info?
10:34
or check som gsyn log
10:34
maybe it says why it cant init
10:34
<johnny>
there is no XF86Config anymore.. gone for ages..
10:34
<myjess>
oh, whoops, I renamed xrog.conf when I put the fdi bit in.
10:34
<johnny>
also.. there should be no reason to edit xorg.conf these days
10:34
pretty sure even synaptics doesn't require it
10:35
altho.. perhaps the actual app gsyntapics still does
10:35
<myjess>
Also, I have two trackpads, one on a wireles keyboard. I wonder if that is why I don;t believe the settings are working on the wireless k/b.
10:36
hmmm, I'll have to look to see how to setup two trackpads.

johnny, I figured out my problem last night. I had sshd configured to only accept ssh key authentication and not password authentication. If i turn that off it works.
11:19
<johnny>
ah.. yes.. i was going to ask you about ssh next
11:20
mannyv, a near future (hopefully) version of ldm will be using libssh instead of trying to parse the ssh output manually..and we'll be able to show more useful error messages instead of just killing the X server and starting over
11:21
which makes it really difficult to figure out why it isn't working without reading /var/log/ldm.log

why would it ?
14:01hersonls has joined #ltsp

johnny, https://help.ubuntu.com/community/UbuntuLTSP/LTSP-Cluster/ - "Thin clients need 32-bit chroot. Build that one this way in root server."
14:01
<johnny>
ah
14:01
i wonder why
14:02
probably not really..
14:02
i just wonder if the sentence is not worded correctly
14:02
<Lns>
that's what i was hoping ;)
14:03
<johnny>
i would guess that is the case, unless there are just no binaries built for amd64
14:03
(if there are binaries)
14:03
<Mava_>
could writer want to stress that i386 clients needs i386 chroot ?
14:04
<johnny>
yes.. that's my guess
14:04
Lns, i would just try it
14:04
if so.. fix the wiki page
14:05
<Mava_>
ou jees
14:05
quote : " We need two x86_64/amd64 servers."
14:06
<Lns>
johnny, well i was just reading up on ltsp-cluster and how it worked..i do have a test server i should be playing around with it on thou
14:07
<Mava_>
mm mm,, test servers are the best :P

anyone able to help me - i install ltsp-server-standalone got everythign working fine. I do a reboot of my machine and now my dhcp3-server and my apache server don't load automatically.....any suggestions?
15:04
<johnny>
well apache isn't related to ltsp
15:04
so.. that's unrelated
15:04
nothing we can help you with here
15:04
you should read logs
15:05
what happens when you manually try to start it
15:05
<grspence__>
yeah everything comes up fine
15:05
(when i do /etc/init.d/dhcp3-server restart)
15:05
ltsp-standalone is the only package i've installed / changed in past fortnight....
15:06
just thought it might be related
15:10cliebow has quit IRC
15:14
<Lns>
grspence__, make sure dhcp3-server is calling the right dhcpd.conf file (ltsp-server-standalone replaces it with /etc/ltsp/dhcpd.cof)
15:15
also make sure a symlink is in the runlevel you're starting at
15:17
<grspence__>
lns - checked the dhcpd config - all fine
15:17
how do i check the symlink?
15:17
<johnny>
isn't there some runlevel editing gui thing you can use
15:17
/me doesn't know much about this on debian
15:17
gentoo makes it so much easier.. i forgot how to do it otherwise
15:17
i just use the gui on fedora
15:17
<Lns>
johnny, everything is easier when you're used to it ;)
15:17
<johnny>
no..
15:17
big difference
15:18
<Lns>
grspence__, 'ls -l /etc/dhcp3/dhcpd.conf'
15:18
<johnny>
you ahve to know what the numberes mean on ubuntu/fedora
15:18
on gentoo ti's just default or boot for most people
15:18Guerdal82_ has quit IRC
15:18
<Lns>
johnny, /etc/inittab shows it
15:18
<johnny>
it's so lame
15:18
<Lns>
not sure about upstart and how it changes stuff
15:18
<johnny>
gentoo's inittab only has 3 entries or so
15:18
it comes with 3 runlevels, boot, default, nonetwork
15:18
that's all
15:18
<grspence__>
greg@aspire:~$ ls -l /etc/dhcp3/dhcpd.conf
15:18
-rw-r--r-- 1 root root 353 2010-05-01 19:45 /etc/dhcp3/dhcpd.conf
15:19
<johnny>
and nobody i know uses nonetwork..
15:19
for 99% of services users add.. it's always default
15:19
rc-update add <service> default
15:19
done
15:19
or just .. rc-update add <service>
15:20
no need to know any number crapola
15:20
<grspence__>
so i just do rc-update add dhcp3-server default?
15:20
<johnny>
grspence__, .. no.. that's gentoo
15:20
i don't know how to do it on ubuntu.. because the stupid number thing and silly commands :)
15:21
Lns, gentoo's initsystem is superior to most init systems that are used on distros
15:21
it's probably even superior to upstart..
15:21
not sure if it's superior to systemd tho..
15:22
<Lns>
johnny, =p perspective my friend, its all perspective
15:22
<johnny>
no.. it's facts
15:22
not perspective
15:22
<Lns>
hahaha
15:22
<johnny>
speed, ease of use
15:22
<Lns>
ok then
15:22
<johnny>
gentoo kills it on both
15:23
oh.. and writing the scripts.. easy too
15:23
<grspence__>
ok so quite bitchin about what distro is best... i'm sure they all have their niceties :D
15:23
on ubuntu any suggestions?!
15:23
<johnny>
grspence__, both fedora and ubuntu use upstart..
15:23
google it.. if Lns doesn't know
15:23
<Lns>
grspence__, it's basically the same as what johnny said on debian based systems,.. iirc "update-rc.d dhcp3-server defaults"
15:23
but i dont' see how it could have gotten removed in the first place
15:24
<grspence__>
yeah i'm clueless why as well
15:24
<johnny>
grspence__, i don't even use gentoo anymore on my desktop machine.. it's just something i miss
15:24
i've been using fedora for almost 2 years now, so i do have some decent perspective
15:24
<grspence__>
update-rc.d: warning: dhcp3-server stop runlevel arguments (0 1 6) do not match LSB Default-Stop values (1)
15:24
System start/stop links for /etc/init.d/dhcp3-server already exist.
15:25
<Lns>
grspence__, what does yoru syslog say after a restart of the machine? There's got to be a clue there somewhere
15:25
i'll bbiab.. taco bell time =p
15:27
<johnny>
my guess is that you have a problem somewhere else .. perhaps your network isn't available when it needs to be..
