I upgraded my LTSP box from dapper to hardy; did the update-...-stuff; deleted the old client files and created new ones; now i want to boot, i do not get a login screen - instead the console says: mktemp: cannot create temp file /tmp/tmp.[someHash]: Read-only file system
03:33
and, in addition (next line):
03:33mikkel has joined #ltsp

<Briareos>
/usr/lib/ltsp/configure-x.sh: line 27: ${TEMPFILE}: ambiguous redirect
03:34
( i guess the latter is because it couldn't create the tempdir in the first place)
03:35
tmp is world writable, by the way
03:35
any ideas?

maybe it's got to do with the (new?) filesystem in /opt/ltsp/images/i386.img.tmp
03:42
?

<majikins>
hi - I've been reading about LTSP v5 - I'd like to test and would like recommendations on thin client hardware
08:52
<Briareos>
majikins are you german by chance?
08:52
<majikins>
nope - South african :-)
08:53
<Briareos>
then this one on installing: https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall ;)
08:54
i cannot yet recommend any TC's, because i am only using old computers in our network here
08:54
they do work fine
08:54
<majikins>
we looking to do this in an office environment - old pc's won't look 'nice'
08:55
<Briareos>
those caught my attention today in a catalogue: http://www.chippc.com/
08:55
are you setting up a complete new office or "upgrading" an existing one?
08:55
<majikins>
new office
08:56
<Briareos>
okay
08:56
have a look at the jackpc from the link i sent you
08:56
if you decide to test them, it would be great if you could mail me your experience report
08:57
because i think that's got probably the most "style" - just mount it into the wall :)
08:57
or table :)
08:57
<majikins>
I'll see if I can get a distributor in south africa
08:58
what about this - can you run firefox natively on a thin client and run the rest of the applications off the server?
08:58
ie - there is an environment we are looking at where users will be running flash intensive apps regular
08:59
<Briareos>
majikins .. well if you want to use "fat" features of the client you could install some system on it - and run ltsp in an extra window ...
08:59
<majikins>
so that can be done then
08:59
some thin clients do have firefox loaded by default
09:00
<Briareos>
majikins - for example with vmware on the client - but I guess there is a simpler way as well
09:00
majikins ah - didnt know that

Hi, I have 2 dhcp servers on my network, 1=the adsl router, 2=the ltsp server. Pxe clients correctly get ip addresses from the ltsp server because the adsl router doesn't offer a boot filename. But on the second dhcp request the router answers first and they fall to busybox. Can I instruct ipconfig to ignore dhcp offers that don't include a boot filename?
09:29
<klausade>
alkisg: you must shut one of them of.
09:30
<alkisg>
klausade, the ltsp server is my laptop, and I change labs all the time, I can't do that
09:30
the problem is with ipconfig
09:31
pxe booting is OK with all routers that I've tried. The second dhcp request (=ipconfig) is the problem on *some* routers.
09:32
<klausade>
alkisg: never mind the thinclients, what about the other machines on the network when you boot up your second dhcp-server?
09:33
<alkisg>
klausade, it's a school lab: I tell the students to select "boot from network", and once every ltsp client is up, I shut down my dhcp server
09:33
(If necessary, many times no other pcs are around so I leave it running)
09:35
<klausade>
alkisg: what about Using Etherboot with alternate BOOTP/DHCP ports?
09:37
<alkisg>
klausade, I thought about that, but then pxe booting won't work, I'll have to use floppies or CDs etc. So if I can't fix the ipconfig thing, I prefer to temporarily unplug the router cable...

<alkisg>
klausade, I found a workaround, ipconfig should be called with -p bootp parameter. Most routers don't support bootp, so only the ltsp-server will answer.
10:46
-p bootp ==> -c bootp

12:19
<laga>
alkisg: nice. can you document that somewhere?
12:20
<alkisg>
laga, I've sent an email to klibc developer list asking for another switch that demands filename=present, it'll show up soon I guess
12:20Pascal_1 has joined #ltsp
12:21
<alkisg>
laga, e.g. ipconfig -c pxe eth0 ==> demand that filename=present (ignore most routers)
12:21
<laga>
that'd be nifty.
12:21
<alkisg>
laga, because -c bootp, with dnsmasq at least, logs the mac and forever gives the same ip to the same client
12:22
<laga>
it might also be possible to have authoritative and non-authoritative dhcpds, but i'm not sure how ipconfig will like that.. i read about that on the pxelinux web site.
12:22
<alkisg>
I don't like this because I change labs all the time, otherwise -c bootp works fine.
12:22
<laga>
alkisg: well, you can probably kill dnsmasq's cache.
12:22
<alkisg>
Yeap, that's what I'll do until (and if) ipconfig gets a new version
12:23
Why isn't it possible to only do one dhcp request? I mean, keep the pxe ip?
12:24
<laga>
that'd be neat.
12:25
<alkisg>
initrd stuff is way over my head... I'll look into it in a couple of years! :D
12:25
<laga>
often the clients will just work if ipconfig gets the IP from the wrong DHCPd.. at least in my very simple network, because both dhcpds are handing out the same address range ;)
12:26
ogra, where should stuff like alkisg's findings be documented?
12:26
<alkisg>
But then lts.conf is not downloaded
12:26
ogra is at a conference I think
12:27
<laga>
yeah, but he occasionally shows up here.
12:27
you're right about lts.conf. hum.
12:27
ah, it also makes some assumptiions about the address of the LTSP server based on dhcp information AFAIK
12:27
at least that's what i think, i don't use that part of LTSP
12:28
<alkisg>
? How do your clients boot up?
12:28MacIver has quit IRC
12:30Briareos has quit IRC
12:30
<alkisg>
In your case (same ip ranges) if you set a static ${ROOTSERVER} in ltsp_nbd it won't matter where they get their IPs, lts.conf will always get downloaded.
12:32
<laga>
alkisg: i don't use the remote display stuff, i use LTSP for fat clients.
12:32
but you're probably right about $ROOTSERVER
12:33
<alkisg>
You're lucky... my clients are extra thin! :)
12:33
<laga>
heh
12:47
<alkisg>
laga, just for the record, I tried authoritative in dnsmasq and ipconfig just ignored it...

How do I update nbi.img?
13:15
Anyone? How do I update /var/lib/tftpboot/ltsp/i386/nbi.img? update-initramfs in the chroot doesn't do it...

Found it, chroot and then /usr/lib/ltsp/update-kernels. I thought update-initramfs was calling that automatically...

hi - just like to find out somethings about ltsp
16:32
if a terminal is going to be used for flash intensive stuff on a browser
16:33
is there a way to allow for the browser to be on the terminal itself-a and the rest of the applications be served?
16:33alkisg has joined #ltsp
16:35
<majikins>
anyone?
16:36K_O-Gnom has quit IRC
16:37
<alkisg>
laga, I got a reply from the ipconfig maintainer that it would be better if we used the "ipappend 2" option to pxelinux.cfg/default. This way the hardware address of the booting interface would be passed to the kernel, and we'd just have to bring *that* interface up. So everything OK with only the first dhcp request.
16:37
Who should I talk to for this? Ogra?

alkisg: yes, talk to ogra.
16:53
<alkisg>
ok, thanks
16:54
<laga>
i'll look at the pxelinux documentation, this sounds interesting.
16:57
alkisg: i fail to understand how "ipappend 2" will fix your problem. you'll still have to deal with multiple dhcpds. "ipappend 1" sounds more interesting.
16:58
<alkisg>
laga, I'm new to all this. I guess (hope) somehow pxe will pass the ip/netmask/boot filename etc command line to the kernel. I'm still trying to find out how can I see the parameters that were passed to the kernel!
16:59
<laga>
http://syslinux.zytor.com/faq.php - have you read this?
16:59
IPAPPEND flag_val [PXELINUX only]
16:59
^^ that paragraph is interesting
16:59
ip=<client-ip>:<boot-server-ip>:<gw-ip>:<netmask>
17:00
the boot file name won't be passed on, but who needs that?
17:00
<alkisg>
Yes, the info is enough, I wonder why it says it's not recommended though...
17:01
<laga>
because it's probably better to run a real DHP client.
17:01
one which will renew a DHCP lease ;)
17:02
just a guess, though. maybe there are even better reasons.
17:03
<alkisg>
...and I wonder if we can also use the same technique when booting from floppy/cd/hard disk
17:04
<laga>
IPAPPEND or passing the config manually?
17:05
<alkisg>
You're right, I guess manually won't be a problem if we boot from a disk
17:05
<laga>
yeah, and IPAPPEND won't work unless you use pxelinux :)
17:06
<alkisg>
is pxelinux from a disk possible? I thought they used etherboot only...
17:06
<laga>
though it might make things easier if you use alternate DHCP ports so you dont have to tell ipconfig to use a different port.
17:06
alkisg: it's only possible via pxe, that's my point :)
17:07
<alkisg>
The problem with alternate dhcp ports is that you lose pxe booting
17:07MacIver has joined #ltsp
17:07
<laga>
alkisg: no, you can still use etherboot
17:07
<alkisg>
So you *always* have to use a floppy or cd
17:07
(unless your cards rom can be reprogrammed... anyway)
17:08
<laga>
you can even write etherboot to your NIC's eeprom.. or put it into your BIOS rom. if you can. ;)
17:09
<alkisg>
laga, I've yet to see a nic with programmable bios (without eeprom programmer)! Maybe my hardware is very old!
17:09
<laga>
there are too many solutions for just one problem, it's making my head spin. i wonder what more knowledgeable people have to say about IPAPPEND
17:10
<alkisg>
The one that answered me was Peter Anvin, you can't get a more knowledgable opinion! :)
17:10
<laga>
heh
17:10
indeed :)
17:11
i guess that it won't work with the .nbi image
17:11
<alkisg>
The only problem would be if my english wasn't good enough to explain him the problem, and he misunderstood
17:11
<laga>
alkisg: i still fail to see how ipappend 1 would solve anything. but it's late and i'm tired, so i might miss something :)
17:12
<alkisg>
why not? I got it working with ipconfig -c bootp, if we get the correct ip we'll just have to do ipconfig ...ip...eth0 etc
17:12
laga, it's late here too, we'd better get some rest! G'night!
17:13
<laga>
ipappend 1 just passes the MAC address
17:13
(AFAIK)
17:13
g'night :)
17:13
<alkisg>
no, that's ipappend 2
17:13
ipappend 1 passes all the info! :)
17:14
<laga>
true.
17:14
um. i better get to bed. :)
17:14
<alkisg>
:D
17:15
<laga>
i swear i've read it like three times
17:15
<alkisg>
Well, Peter told me about ipappend 2, so you're half right
17:15
I'll have to ask him what he meant.
17:17
<laga>
yeah, that's what i meant. phew.
