Does LTSP support AIGLX (on hardware that's supported by X.org)?
00:15
<vagrantc>
yay! the ltspfsd -> ltspfsd + ltspfsd-core split made it in debian. ltspfs has 0 reported bugs! :)
00:16
<cyberorg>
vagrantc, hi, http://ars.userfriendly.org/cartoons/?id=20090405 :)
00:18
<vagrantc>
heh
00:18* vagrantc suspects there are more debian derivatives than red hat...
00:18
<vagrantc>
cyberorg: so, an otherwise mostly working xrdp is just totally borked with that last patch
00:19
<cyberorg>
vagrantc, test rdesktop -s locally
00:19
<Ryan52>
cyberorg: haha. nice.
00:19
<vagrantc>
cyberorg: so i'm guessing there's some significant differences with xrdp in debian vs. opensuse
00:19
cyberorg: yeah, i was planning on trying that sometime.
00:19
<cyberorg>
vagrantc, lets figure out if it takes Name or Exec, we can work on it accordingly
00:20
<vagrantc>
cyberorg: it just plain crashed
00:20
no rdesktop process running, ldm log entries saying that the X session was finished
00:20
<cyberorg>
rdesktop -u username -p password -s shell localhost
00:20
<vagrantc>
so running rdesktop manually would probably give us a useful error
00:21
<cyberorg>
vagrantc, you can run that on the xrdp server directly
00:21
<vagrantc>
cyberorg: as if i had a GUI on the server!
00:21
actually, i do. but i often don't. :)
00:22
<cyberorg>
then from another PC that has rdesktop and GUI :)
00:24* vagrantc must tend to dinner
00:25
<Ryan52>
so my patch broke stuff, eh? I really shouldn't code stuff that I don't understand and can't test.. :P
00:25
<vagrantc>
Ryan52: yeah, doesn't work for me, at least.
00:26
i don't know how it could possibly support "rdesktop -s", the way it's configured on debian. it simply sources /etc/X11/Xsession with no arguments.

Ryan52: cyberorg disappeared
00:58
<Ryan52>
no, he reappeared.
00:58
=P
00:58
<vagrantc>
cyberorg: so, i'm filing a bug on debian's xrdp, as the way it's implemented, i don't see how it could possibly support anything but the default.
00:58
<cyberorg>
vagrantc, sorry, having connection troubles
00:59F-GT has quit IRC
00:59
<cyberorg>
vagrantc, -s does not work at all?
00:59* Ryan52 wonders why suse's would be different than debians..
00:59
<vagrantc>
it's got a big fat patch on it
00:59
cyberorg: doesn't work with Name or Exec. it just uses the default.
00:59
<cyberorg>
Ryan52, over a year of "secret" development
01:00
i am a bit annoyed too, the developer does not communicate much :(
01:03
vagrantc, hopefully all the work done will go upstream xrdp/rdesktop one day
01:04Egyptian[Home] has quit IRC
01:04
<cyberorg>
i doubt suse would want to maintain such a huge patch

vagrantc, you know if any other distro has xrdp?
01:09
<vagrantc>
cyberorg: surely ubuntu...
01:09
<Ryan52>
cyberorg: there's a program called whohas that can answer that :)
01:09
<cyberorg>
do they have newer than debian?
01:09
<vagrantc>
cyberorg: same version
01:09
<Ryan52>
cyberorg: http://slexy.org/view/s213f1due7
01:10
more readable: http://slexy.org/raw/s213f1due7
01:10
<cyberorg>
looks like gentto and suse has newer
01:10
mandriva too
01:11
Ryan52, can you do whohas whohas?
01:12
<Ryan52>
heh. ya, one sec.
01:12* vagrantc wonders where Ryan52 gets this command from
01:12
<cyberorg>
vagrantc, thats why i asked :)
01:12
<Ryan52>
vagrantc: it's this thing called Debian...you should try it sometime. =P
01:13
<vagrantc>
Ryan52: "apt-cache search whohas" gives me nothing
01:13
ah, it's not in stable.
01:13
<Ryan52>
vagrantc: http://packages.debian.org/sid/whohas
01:13
yes, it's new.
01:14
cyberorg: it's apparently timing out, but...this is what it said so far. http://slexy.org/raw/s20Gk6M1Ku
01:14
<cyberorg>
great looks like someone has packaged for suse
01:15
<Ryan52>
ya, that's it.
01:15
<cyberorg>
Ryan52, thanks, installed :)

01:29
vagrantc, can you login to client and see ps axww to find out what rdesktop command is used?
01:30
currently here it uses "KDE 4.2" serverIP
01:31
that is "Name" in quotes
01:31
<vagrantc>
cyberorg: well, the patched version breaks instantaneously, so rdesktop isn't running.
01:31
<cyberorg>
zirconiumks, how do you get rdesktop command in ldm.log?
01:33
<vagrantc>
cyberorg: ??
01:33
<cyberorg>
vagrantc, add loginfo to get command in ldm.log
01:33
<vagrantc>
ah.
01:33
cyberorg: some other day :)
01:33

ok :)

03:06

03:06

i think its an intel - its at home so I can't tell you exactly right now
03:07

you know what firmware it runs?

<Drakonen>
hello, i hav e aproblem with xrdp and ltsp. we have some small "chippc"s which do rdp. we want to connect them to ltsp, but when the xrdp session starts, it looks like they are in a different X environment. when i PXE boot an other machine, it looks fine (and i can configure it better). does anyone here know how to make xrdp use the same resources as a PXE booted session?
03:08
<cyberorg>
ok, give it a try and let us know how it went :)
03:08
<k-man>
thanks cyberorg
03:08
<Drakonen>
i hope that makes sense
03:09
<cyberorg>
Drakonen, no it doesn't, what resources?
03:09
<Drakonen>
the chrooted env, which is used when using pxe booting
03:09
does it use that?
03:10
how do i know actually if im chrooted or not?
03:11
<cyberorg>
Drakonen, does the chippc have an embedded OS? if so it will not use ltsp's chroot, LTSP however can also do rdesktop to connect to xrdp server
03:11johe has quit IRC
03:12
<Drakonen>
the chip pcs's have win ce or something like that, and they can do rdp
03:12
i have xrdp installed, and its working
03:12
<cyberorg>
can chippc do pxe booting?
03:12
<Drakonen>
but, it looks different (like the theme settings are missing)
03:13
cyberorg: not that i know of
03:13
i'll have to check
03:13
*doing now*
03:16
doesnt look like it
03:17
<cyberorg>
so there is no way for it to use ltsp's chroot
03:17
<Drakonen>
can i make xrdp use the chroot?
03:19
<cyberorg>
chroot does not have anything to do with xrdp, it is just minimal OS that starts rdesktop/ldm
03:20
<Drakonen>
aaaah
03:20
that makes sense
03:24
when i start something from the preferences pane, i get an error: :unable to starts the settings manager 'gnome-settings-daemon'. ..."
03:24
ths is from an xrdp session

hi jammcq. tried our live DVD yet?
09:03

saw the announcement, looks cool
09:03* cyberorg pimps http://download.opensuse.org/repositories/Education/images/iso/
09:03
<jammcq>
cyberorg: you should join us in Brazil, to talk about it
09:04
<cyberorg>
Ryan52, this one now got your nomad changes in too
09:04
jammcq, i would love too, but it would cost me about USD2000, not a small fortune here ;)
09:05
<jammcq>
sure, It's expensive. would be great if there were some sponsorship money available
09:05
but money is soooo tight these days
09:06
<cyberorg>
i can't ask novell, they just paid about $500 in feb for a trade fare we participated here
09:06
so probably some other time :)
09:07
<jammcq>
you actually got money out of Novell ?
09:07
good job
09:07
<Nubae>
when is Brazil exactly?
09:07
<jammcq>
June 24-26
09:07
or 24-27
09:07
something like that
09:07
<Nubae>
of May?
09:07
<jammcq>
we're arriving on the 23rd and leaving on the 29th
09:07
june
09:07
<Nubae>
k
09:07
<cyberorg>
jammcq, yes, they sent me a cheque, they are quite supportive and generous here
09:07
<Nubae>
yeah guess it makes sense to stay extra days
09:08
<jammcq>
Nubae: yeah, there's always a big community BBQ on the sunday after the conference
09:08
so I like to stick around until monday
09:08
last year, I stayed until tuesday
09:08
one of these days I'll stay an extra week, and go visit the falls or something else
09:09
<Nubae>
how about accommodation?
09:12
wow tickets are cheap... 700€ from Vienna - Floranopolis
09:13
<jammcq>
if you are giving a talk at the conference, they cover the cost of the hotel
09:13
porto alegre is where you'll need to be
09:13
<Nubae>
oh
09:13
<jammcq>
"POA" is the airport code
09:14
<Nubae>
thought florianopolis was closest
09:14
<jammcq>
nope, POA is bigger too
09:14
<Nubae>
ok, should be about the same price in any case
09:15
so, how does one give a talk?
09:15
<jammcq>
there's a call-for-papers that's open
09:15
but if you are serious, I could prolly hook you up with the right people to get it approved
09:15alkisg has joined #ltsp
09:15
<Nubae>
wow even cheaper... to porto alegre, worth taking the time
09:15
well, I could talk about fatclient
09:15
I think it could be interesting
09:16
<jammcq>
I'm friends with the guy who organizes the conference tracks
09:16
<Nubae>
maybe talk about that and local apps, if no one else is talking about that
09:16
<jammcq>
scotty will be there too, talking about something LTSP related
09:16
my goal is to get several LTSP developers there, and have a panel discussion
09:16
<Nubae>
well, I'm definitly considering, the price is right
09:17
<cyberorg>
Nubae, you can represent our fatclient too ;)
09:17
<Nubae>
hehe
09:17
<cyberorg>
you wont have to talk much http://en.opensuse.org/LTSP/Fatclient :)
09:17
<Nubae>
have to install and check it out first ;-) I'm just installing Suse now
09:17
<ogra>
dont you talk like that about your clients ... that channel is publically logged !
09:17
;)
09:17
<Nubae>
lol
09:17
<jammcq>
he means "phat" clients
09:18
<Nubae>
we should do kewl clients too
09:18
running on heat efficient processors
09:18
<cyberorg>
ogra, in this recession all the fat clients need to lose some
09:19
Nubae, wait, do it from live DVD
09:19
<Nubae>
do what from livedvd?
09:19
<cyberorg>
uploaded new image, it now also has gobby(ogra now you can grab it too)
09:20

I sent laserjock a whole list of edu apps that I tested that should go into edubuntu-addon (universe), u want me to send them to u too?
09:21
<cyberorg>
Nubae, sure, why not :)
09:22
if they are missing from http://en.opensuse.org/Education/Applications
09:22
<Nubae>
email?
09:22
<cyberorg>
cyberorg at opensuse.org
09:24
<Nubae>
ok, sent, I took a look at that list, some are in there, but a lot of stuff isnt... there are notes on the apps that I took too
09:24
it will be nice if we can homogenize the edu apps, so the same is available in suse and ubuntu

good morning
09:30
so ... anyone have experience any problem with 10/100 switchs and 10/100/1000 client nics?
09:30
<Nubae>
I see just rpm based distos in there though
09:30
maginot: no
09:31
<cyberorg>
Nubae, yeah, but oBS can build xBuntu, debian, today the first ARM debian lenny package was built :)
09:32
Nubae, and the live DVD is also built there
09:32
<maginot>
Hmmm pidgin on the clients is crashing ... I dont know if this is just a coincidence because this kind of problem wasnt happening in the old clients who was using 10/100 nics
09:35
<Nubae>
my Dad bought a HP tablet PC for 900€, those things are seriously dropping in price

35 clients 10/100
09:53
the only gigabit connection is between the ltsp server and the firewall
09:53
<tadeu_>
great, thanks
09:54
<maginot>
but Im planning to make all gigabit, the new clients already have gigabit nics, only the switchs tey are connected are 10/100

Hello. I hope everyone is doing well and having a good day. I thought to post a software RAID question here before I venture into the scary IRC channel of Centos :)
10:33
I've got a CentOS machine running on a single drive no problem. I wanted to add 2x400 GB drives as a RAID 1 mounted onto root for backing up my ltsp server
10:34
The problem - the size of the array is different than the size of the individual drives.
10:34
Each drive is 400 GB.
10:34
the array only reports 137 GB total.
10:34
fdisk reports 400 GB, mdadm reports 400 gb but DU reports 137
10:35
I tried writing a bunch of drives to see what the physical limit was, and reported an error and running out of space at 137
10:35
So I'm not sure what to do. Thanks.
10:38
Sorry, I meant the command df not du.

TheProf, do you get the same result if you don't have the drives in a RAID config?
11:04
<TheProf>
pscheie_: Hello. If I access each drive separately they show the correct 400 gb
11:05
it's only when I put them together their size decreases.
11:07
<pscheie_>
TheProf, Centos 5?
11:08
<TheProf>
Yes - 5.3
11:08
The steps I used to create the array are here http://mark.kolich.com/2008/11/howto-setup-and-configure-linux-software-raid-centosfedoraredhat.html
11:10
mdadm -D /dev/md0 shows me "Array Size : 390711296 (372.61 GiB 400.09 GB)"
11:11
df -h shows me "/dev/md0 126G 126G 0 100% /mnt/network_backup"
11:11
fdisk -l shows me two entries - hdc, hdd - each "Disk /dev/hdc: 400.0 GB, 400088457216 bytes"
11:12
So I am confused.

11:22
<morrocolinux>
ltsp project is freezed ?
11:23
<pscheie_>
TheProf, I noticed in the release notes for 5.3 that there seemed to be some 'regressions' but nothing related to mdadm
11:23
(just some obscure stuff we care about in my office, not ltsp related)
11:24
<TheProf>
pscheie_: OK. it's strange because I tried it with two entirely different computers - a Pentium 1 and a P4 celeron. Completely different except for the drives.

TheProf, sounds like a filesystem limitation; and '137GB' rings a bell, but I can't put my finger on it.
11:30intelliant_ is now known as intelliant
11:31
<pscheie_>
TheProf, did you try just setting up one drive separately? That is, partition, create filesystem, then run df?

<TheProf>
pscheie_: I just tried to do as you recommended and it didn't work! I unmounted the raid, stopped the raid, and then mounted the individual drive with mount /dev/hdc /mnt/network_backup and then df and it only reports 126 GB
11:41
this is bizarre
11:43
<pscheie_>
TheProf, but that's progress of a sort: the issue is the file system, not the raid
11:44
<TheProf>
pscheie_: True.
11:44
THere is nothing of value on these drives so if we need to blow everything away we can if that will help.

I believe you're using vagrantc's backport for Debian right ?

stgraber: i'm using sqeeze in the chroot

that would explain it?
11:59

yes

you'd need jaunty in Ubuntu to get the same version of LTSP
12:00

hmm.. i might stick with squeeze then
12:00
though i'm trying to test on a load of different thin clients, getting xserver issues, thought ubuntu might have been better in that regard

Ubuntu has some fix in Jaunty for most of the thin clients I have at the office

FX160 ?
12:11

that brings to to my SiS chipset capability question
12:11
it's the Dell 160 I was thinking about buying
12:11
<stgraber>
it's not supported
12:11
there was an experimental driver in Intrepid (from a PPA) but in Jaunty the best you get is VESA
12:12
I guess someone is still working on a real driver for these SIS chipsets
12:12
even the onboard Linux on the FX160 is using VESA
12:12
<MRH2>
ok that's it off my list then
12:12
shame they didn;t go for intel

12:13

even the SIS driver couldn't detect the resolution
12:13
you have to force it by hand with X_RANDR_MODE0 (or similar)
12:14
<dmarkey>
oh really
12:14
can i have different x configs for different clients

TheProf, ext3, which I assume you're using, has filesystem sizes in the TB range, so it seems unlikely that's where the problem lies.
13:24
TheProf, what if you try a different distro/kernel? Say, boot a knoppix disk in the machine, work with that, see if you get the same results
13:24
<TheProf>
pscheie_: You are correct it's ext3 -- I used that type to create the partition.
13:24twinprism has joined #ltsp
13:25
<TheProf>
pscheie_: I understand what you're saying -- I am just confused as to why some parts of the OS see the 400 GB and du doesn't. I don't have access right now to anything else since I have ssh access only now but I can try that option also.
13:26
pscheie_: could it be I partitioned/fdisked the drives wrong?
13:26
<pscheie_>
TheProf, perhaps. Could also be this:
13:27
https://answers.launchpad.net/ubuntu/+question/59059
13:27
although this is ubuntu
13:28
<TheProf>
Well it's almost identical issue!
13:29
Strange - I used two different motherboards and got the same issue. I'll try going through their list of steps
13:29
<pscheie_>
Are the mobos from different manufacturers?
13:30
<TheProf>
They are completely different machines. about 10 years apart. I will check the manufacture now
13:35
pscheie_: both are Intel motherboards.
13:35
One was a pentium II 550 Mhz, this is a celeron 2.0 ghz
13:36
The drives are both indentical seagate drives
13:37
<pscheie_>
TheProf, try splitting the drives into multiple partitions, see if you at least see them all/ can access them, just to try to narrow the issue.
13:37
<TheProf>
pscheie_: ok will do so now
13:38
<Lns>
TheProf: i'd rule out that the drives simply weren't partitioned the differently before you do anything else...
13:38
<TheProf>
Lns: Sorry I don't understand.
13:39
<Lns>
TheProf: how big are the drive sizes?
13:39
<pscheie_>
Lns, I think he gets the same result with just a single drive, no raid; but you are correct, that should be verified.
13:40
<Lns>
TheProf: also, i'm hoping you meant 'df' not 'du'
13:40
<TheProf>
they are 400 gb. fdisk reports 400 gb correctly.
13:40
<pscheie_>
TheProf, suggest you leave out all the raid stuff just to keep it simple.
13:40
<TheProf>
Yes I meant df
13:40
pscheie_: I've stopped the raid
13:40
and only mounted one drive
13:41
<Lns>
TheProf: have you verified that the partition(s) on the drive take up the entire drive?
13:41
<TheProf>
fdisk -l /dev/hdc shows me:
13:41
<Lns>
(df will give you numbers based on the filesystem, not the actual drive size obviously so if the partition doesn't take up the whole drive, you aren't going to see it in 'df')
13:41
<TheProf>
2 heads, 4 sectors/track, 97677846 cylinders and that
13:42
dev/hdc1 1 97677824 390711294 83 Linux
13:42
so from what I can understand, the drive has 97677846 cyl
13:42
and that they are all being used with hdc1
13:43marius-- has quit IRC
13:43
<TheProf>
if it's easier I can either 1) remove and recreate the partition or 2) remove and create multiple partitions to test
13:44topslakr has quit IRC
13:44
<Lns>
well the fdisk info does look like it takes up the whole drive.. i could see that the older PII might not see the whole drive, but not the celery 2.0
13:45
well that's not true actually...might want to verify w/the mobo/bios support
13:45
<TheProf>
I was getting annoyed with how it wasn't working with the old machine (it was actually a PI but I upgraded the CPU) so I pulled everything out and slapped them into a new one.
13:45
<Lns>
TheProf: did you repartition after you put it in the new one?
13:46
<TheProf>
Lns: No.
13:46
I can do that now.
13:46
<Lns>
TheProf: is it possible it has a drive overlay software on it from an old install?
13:46* Lns is just throwing out ideas
13:47
<TheProf>
Lns: all ideas are welcome :) they are newly purchased refurbished drives. The machine has the OS on a 6 GB drive then these for RAID
13:47
I can just to make sure, delete the partitions and recreate them now.
13:47
I tried using cfdisk but it won't start - generates an error so I'll use fdisk
13:47
<Lns>
TheProf: what's the error?
13:48
<TheProf>
fatal error - cannot seek on disk drive.
13:48
but that could reference the OS drive
13:48
<Lns>
yikes
13:49
<Treyh>
when you run ltsp-build-client on intrepid, it fails unless i specify a mirror, is that normal
13:49
<Lns>
well obviously you want to give cfdisk the drive as an argument (cfdisk /dev/hdc)
13:49
<TheProf>
Lns: doesn't matter which device.
13:50
it can't be that *3* separate drives are ALL failing
13:50
<Lns>
TheProf: were they *all* in the old machine?
13:50
<TheProf>
hmm...I think I know where this is going. Yes they all were for a few days.
13:50
<Lns>
Treyh: i wouldn't assume so.
13:50
<TheProf>
The OS was for a few weeks, the 2 new ones for a few days.
13:51
<Lns>
TheProf: if they were partitioned in the old machine i'd repartition them..that's a strange error though
13:51topslakr has joined #ltsp

<TheProf>
I'll repartition them now
13:53
Deleted all partitions on both 400 gb drives.
13:56
<pscheie_>
TheProf, you may want to reboot; changing partitions on the non-primary drive shouldn't require a reboot, but I've seen cases where the kernel still held onto the old partition table.
13:56
If you still have trouble with the drive, that is.
13:57Treyh_ has joined #ltsp
13:57
<TheProf>
pscheie_: these are non-primary drives but even after I removed the partition and quit fdisk writing the change I find that the command lshw is showing them reporting 127 Gib so I will reboot
13:57
<Treyh_>
i bet using the --mirror of ubuntu when i built the client caused my ioctl error
13:58
<TheProf>
pscheie_: hmm...I just realized I've got an fstab entry for the raid.
13:58
oh well - when it boots I'll remove it and reboot.

it also lists it as ext3 even though there are no partitions. How is that possible?

Hello TheProf
14:15Treyh has quit IRC
14:15
<TheProf>
I'm having a problem where df is reporting 127 GB limit
14:15
when the drive is actually 400 gb
14:15
some commands report one size, other commands report another size
14:15
<Treyh_>
interesting
14:15
what distro you running
14:15
<TheProf>
centos 5.3
14:15
trying to make a backup machine for my ltsp server
14:15
<Treyh_>
is that end of life?
14:16
<TheProf>
so I got 2x400 GB drives for a mirror raid.
14:16
5.3? no that's just released a week ago
14:16
Good for a few more years at least
14:16
<Treyh_>
Sorry I don't keep up with CentOS
14:16
32 or 64 bit system
14:17
<TheProf>
Treyh_: No problem.
14:17
32 bit system
14:17
OS is on a 4 GB drive drive.
14:17
these are additional drives
14:17
<Treyh_>
did you completely format them
14:17
<TheProf>
to be put into a software raid array and mounted
14:18
the only step I didn't do is the specific format command. I partitioned then ran mkfs.ext3
14:19
Which I thought was the same process as formatting
14:19
<Treyh_>
yea
14:19
so you ran say fdisk /dev/hdb
14:19
then created partitions?
14:19
<TheProf>
correct
14:20
<Treyh_>
yea you did it right
14:20
<TheProf>
went with defaults for 1 full primary partition the whole size
14:20
<Treyh_>
sounds strange
14:20
<TheProf>
Indeed. I just removed all the partitions off the drive.
14:20
I will try to create one now.
14:20
<Treyh_>
do it manually
14:20
type in the size you want
14:20
and do something like 380000mb
14:21
<TheProf>
it asks me based on cylinders.
14:21
<Treyh_>
ouch
14:21
hmmm
14:21
<TheProf>
I was going by the min and max that fdisk reported
14:21
<Treyh_>
that will work unless thats wrong
14:22
<TheProf>
ok
14:23
<Treyh_>
i'm trying to think
14:23
reminds me of the times i had to install openbsd
14:23
on a mini firewall, with a flash card as a hd
14:24
<TheProf>
Nice.
14:24
I was able to enter a size rather than cylinder
14:25
<Treyh_>
cool, what size did you enter
14:26
<TheProf>
+400000M
14:26
some sort of approximation :)
14:26
<Treyh_>
lol that will probably fail
14:26
better to go with 385000M
14:26
<TheProf>
I wanted something close to 400 GB
14:26
it was accepted :)
14:26
<Treyh_>
cool
14:26
i hope it works
14:27
how long til you will know?
14:27
<TheProf>
lshw actually is reporting a larger size!
14:27
well the partition was already created.
14:27
I tried to mount it but it says that I have to specify a filesystem type
14:27
probably because I didn't format it?
14:28
<Treyh_>
thats a fdisk option
14:28
i know type 66 is for bsd
14:28
not sure about ext3
14:28
i'm an old school freebsd guy
14:28
<TheProf>
ok
14:28
<Treyh_>
but i think thats where your failure was at
14:28
your cylinder count was wrong
14:28
<TheProf>
it's automatically set to linux - type 83
14:29
I guess I need to run that mkfs.ext3 command

yea probably wouldn't hurt
14:29
i'm reading about it now
14:30
this site says to do mkfs -t /ext3 /dev/hdb1
14:30
but just do your normal command you'reused to
14:32
it work?
14:32
<TheProf>
I just ran mkfs.ext3 -b 4096 /dev/hdb1
14:32
it's processing now.
14:32
<Treyh_>
i have to go soon
14:32
i want to know if it worked lol

14:33
now do you know anything about ltsp on intrepid ?

14:34
seems like ltsp works on it
14:34
but not for intrepid
14:34
<TheProf>
I am very non-experienced with LTSP beyond straightforward stuff.
14:34
So my apologies!
14:35
However I will say this channel will have someone who can answer it come along sooner or later.

Nubae, Lns: I've timed the boot times of my ancient lab PCs - from grub to ldm, fastest = 700MHz = 50 secs, slowest = 300 MHz = 1 min 10 secs.
14:51
So I was about right the other day that we were talking about boot times...

alkisg: ok? :)
15:37
(not sure where you're going with it, i don't remember a conversation about boot times recently :) )
15:39
<alkisg>
No, nowhere, just reporting the actual boot times, because 2-3 days ago that we talked about it I hadn't actually timed the booting process...
15:39
Nevermind :)
15:41jammcq has quit IRC

Lns: 50 seconds is a long time for booting a 10 year old pc?!!!
15:43
<Lns>
the hardware itself, i wouldn't think anyway, has a whole lot to do with it (as long as it's not a 486 anyway!)
15:43
the network would have much more to do with it, or a bootup-specific issue
15:44
<alkisg>
nubae was expecting them to boot in many minutes, that's why I was reporting the actual boot times...

Lns, I agree with you, 64 mb ram and 400 mhz PCs are fine for ltsp - that's what I was saying... http://www.nubae.com/logs/ltsp20090406_pg3.html
15:48
Anyway, nevermind, I just happened to count the boot times today, no big deal
15:50
<Lns>
alkisg: ahh gotcha
15:50* Lns doesn't have a great memory =p
15:50
<alkisg>
It's just that I keep hearing that "ltsp clients need 256 ram" lately, and I wonder why
15:50
(if no localapps are needed, of course)
15:51
<Lns>
alkisg: lately as compared to in 4.2 ?
15:51
<alkisg>
No, lately = the last few months in the mailing list, here in the irc...
15:52
<Lns>
alkisg: ah. well obviously it doesn't hurt to patch issues like the pixmap thing, localdev/localapps, the fact that ltsp5 uses distro kernel/utils instead of a totally optimized one for low power machines
15:53
alkisg: 256mb is the new 32mb ;)
15:53davidj has quit IRC
15:53
<alkisg>
Well, all those things run fine with my 64mb clients, that's all I'm saying.
15:53
<Lns>
alkisg: even with using firefox, flash/java, openoffice, etc?
15:53
under gnome ?
15:53
<alkisg>
Yes, but of course not as localapps
15:54
<Lns>
right
15:54
<alkisg>
The right click firefox bug is there, sure, but otherwise it's ok
15:54
<Lns>
i was just talking about the pixmap
15:54
that's so weird, i've never run into that problem
15:54
you've optimized ff3 right?
15:54
(via the wiki entry i made)
15:55
<alkisg>
Nah, Gadi gave me a patched library, I tested and was significantly faster, but I didn't put it at the schools
15:56
I'd like a patched SDL on the other hand :)
15:57
<Lns>

would you guys recommend using the alternative ubuntu intrepid install
17:32
or downloading intrepid and building it by hand
17:32
or using ubuntu 8.0.4.1 and building it by hand

ogra: "ubuntu" is a Debian based GNU/Linux distrubution that includes a Ubuntu specific version of LTSP. It can be found at http://www.ubuntulinux.org. to install ltsp on ubuntu: https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
17:33
<ogra>
see the latter link
17:34Nubae has joined #ltsp
17:34
<Treyh>
my question is which would you guys recommend
17:34
hardy or intrepid
17:34
<ogra>
intrepid
17:34
unless you want to buy commercial support for it
17:35
<Treyh>
the problem is that i've installed using the alternate cd
17:35
and installed intrepid directly and custom built it
17:35
the end result is the same
17:35
the client doesn't finish booting, the splash screen freezes on the third bar
17:36
talked to a few in here, turned on quiet splash and the errors at the bottom are normal
17:36
<ogra>
the result isnt the same, since you configured it manually :)
17:36
<Treyh>
one suggested it to be a nbd problem
17:36
same problem on both setups, freezes at login
17:36
<ogra>
at login ?
17:36
<Treyh>
i mean freezes at splash screen
17:38
any suggestions?

17:40
<Treyh>
yea that was some of it
17:40
<Lns>
Anything above that that would have caused those errors?
17:40
(looking for the first indication)
17:40
<Treyh>
i am bringing it up now
17:41
<Lns>
Whatever it is, it's killing your network and/or nbd connection to the server
17:41
<Treyh>
so could be a network issue?
17:41
<Lns>
possibly
17:41vagrantc has joined #ltsp
17:42
<Lns>
is it the exact same point every time that it dies?
17:42
<Treyh>
yes
17:42
i'm also using virtual box
17:42
<Lns>
oh yeah
17:43
<Treyh>
anything special that i might have missed there
17:43
i'm using internal net
17:43
i'll switch it to nat and try again real quick
17:43
<Lns>
well that's out of my realm, though I wouldn't think that if it got as far as it did, it'd just die there every time unless your nbd image is corrupted
17:44
<Treyh>
if my nbd image is corrupt
17:44
how can i rebuild/replace it
17:45
<Lns>
ltsp-update-image
17:45
you sure your chroot is complete?
17:45
if you ran ltsp-build-client and it didn't complete successfully you'll have issues
17:45
even if you ltsp-update-image
17:46
<Treyh>
it did complete and i've actually rebuilt it twice
17:46
<Lns>
ah
17:46
<Treyh>
the guide i used suggested to do ltsp-build-client --mirror .......
17:46
<Lns>
you rebuilt the chroot by removing /opt/ltsp/ and then running ltsp-build-client ?
17:46
<Treyh>
so then i switched to just ltsp-build-client
17:46
yes but i only removed /opt/ltsp/i386
17:46
<Lns>
i think that's ok to do
17:47
<Treyh>
when i tried to rebuild it told me what to do
17:47
<Lns>
and you've re-run ltsp-update-kernels too?
17:47
<Treyh>
yes
17:47
and also ltsp-update-sshkeys
17:48
<Lns>
have you tried booting different h...heh, nevermind, you have no real hardware =p
17:48
you're booting a vbox guest?
17:48
<Treyh>
yes
17:48
one thing it might be
17:48
MIGHT BE
17:48
is everytime i reboot
17:48
the static ip i put on eth0 doesn't stick
17:49
<Lns>
reboot the guest?
17:49
<Treyh>
maybe when i do the update ltsp-update-sshkeys it gets freaked out cuz it changes
17:49
yes
17:49
maybe i'm putting the static in wrong
17:49
<Lns>
you don't want a static ip on the guest
17:49
err..client
17:49
<Treyh>
oops
17:49
i mean server
17:49
<Lns>
k
17:49
<Treyh>
the ltsp server
17:49
is there a trick to gettign the static ip to stick?
17:49
<Lns>
no clue...not much vbox exp
17:50
<Treyh>
that is just a ubuntu question
17:50
i put the static ip in thru the network config
17:50
and when i reboot it doesn't stick
17:51
<Lns>
through network manager?
17:51
s/manager/damager
17:51
<Treyh>
i put it in thru network manager
17:51
maybe i need to hard code it
17:52twinprism has joined #ltsp
17:52
<Treyh>
in a file instead of using the network manager
17:52
<Lns>
i usually do, just because network manager on a ltsp server is kinda unnecessary imo
17:52
<Treyh>
what file holds the info
17:52twinprism has quit IRC

/etc/network/interfaces
17:53yanu has joined #ltsp

cool
17:59
<Treyh>
didn't work
17:59
didn't stick
18:00
but found site that suggested to uninstall network manager
18:00
so did and am rebooting
18:04
and had to put the statis back in
18:04
and am goign to reboot again lol
18:06
cool it stuck
18:07
so i'll run the ltsp-update-image kernels and sshkeys
18:09twinprism_ has quit IRC
18:11

ok running the updates
18:11
you still there lns
18:12
<Lns>
yo
18:14
<Treyh>
doing the rebuilds now
18:14
should i reboot after ltsp-update-*
18:14
after the kernels, image, and sshkeys
18:18
<Lns>
the client, yes
18:18
not the server
18:18
<Treyh>
still stuck at the same place
18:19
should i do ltsp-update-image last?
18:19
<Lns>
You've done all chroot updates after rebuilding it?
18:19
<Treyh>
chroot updates?
18:19
i did
18:19
ltsp-update-image
18:19
ltsp-update-kernels
18:19
ltsp-update-sshkeys
18:19
in that order

nono... https://help.ubuntu.com/community/UbuntuLTSP/UpdatingChroot
18:20

just replace hardy with intrepid
