problems mounting nfs root using the dapper nfs server. Thin clients pause for a long time, eventually saying "cannot contact nfs server". Logging on the server indicates successful mount. Problems only on dapper, fine on debian sarge. no firewall rules, nothing in hosts.allow/deny. Where should I start looking ?
01:54
<sep>
wizzy, rpcinfo both localy and towards theremoete host. and from both ends
01:59
<wizzy>
The client is not up yet (/ not mounted) - what am I looking for on the server ? "rpcinfo -p localhost" on the server reports portmapper x2, nfs x6, nlockmgr x6, mountd x6, status x2
02:00
"rpcinfo -p client" says connection refused

Can anyone recommend a 'Fedora 6'-specific how-to for installing LTSP? I have tried the Debian-based how-to and I think I got a little lost when translating the package requirements... ;)
03:34
<bip>
have u checked the ltsp wiki lamaslany ?
03:37
<lamaslany>
I've tried to follow the LTSP Installation Guide by PaulVanGundy but the installation of the prerequsite packages is done using apt-get which I thought was a Debian package manager. Unfortunately I'm still quite new to linux and I was hoping to get a Fedora 6 how-to to ensure that I install the correct prerequsite packages...
03:38
There doesn't seem to be a direct translation of package names between the Debian-base and the RPM offerings.
03:39
I *could* just try any and all of the close matches but if there was already guidance then it seems silly not to utilise it! :)
03:40
Okay, okay, I'm just being lazy - but I'd still prefer to use a how-to from somebody who knows otherwise I might get it working but it not be optimal/secure.

Uhm
04:42
Sometimes ltsp-clients disconnect from X-server, why?
04:43
<McPolo>
What you mean? Xserver is run on the client itself.
04:43
<Megant_>
Yeah, but I mean that they disconnect from ltsp-server
04:43
<kgoetz>
Megant_: are there any logs?
04:45

kgoetz: Uhm, what logs?

That has happened to me only when network disconnects.
04:46
<kgoetz>
Megant_: i'm asuming either the clients or servers are logging
04:47
<Megant_>
where would clients log?
04:47
I guess that i found something from /var/log/messages
04:48
Gconfd got signal 15
04:48
or many gconfds
04:49
about 7 or 8 gconfds got signal at nearly same time

lamaslany, apt exist for red hat fedora as well google for that ;-)
05:44
<lamaslany>
Thanks bip. Would this result in the need to manage two package databases?
05:44
<bip>
no
05:44
it should not
05:44
well u might need to add some specala pat repositoreis
05:44
if u need some package not in maistream fedora repositories
05:45
i cannot be more precise because i m a debian user now ...
05:46
but trust me whan i was using fedora apt was the firt thing i installed into any freshly installed machine lamaslany

lamaslany: As far as I know, in FC results that apt is an interface to rpm, like it's an interface to dpkg in Debian, so you maintain only one package list. But repositories list is another thing.

Does somebody know or remember where does a workstation get its hostname from?
07:07g333k has quit IRC
07:07
<prpplague>
Envite: depends on your boot method iirc
07:08
Envite: if you are using bootp then its generally set in the bootp config file
07:08g333k has joined #ltsp
07:08
<prpplague>
Envite: for pxe boot there is a section of for that
07:08
Envite: you should be able to ready the getting started docs
07:08
Envite: which will include setting up a ltsp client
07:09
<Envite>
it's dhcp
07:10
<prpplague>
dhcp is not a boot method
07:10
dhcp also you get files and sets ip addresses
07:11
<Envite>
well
07:11
dhcp gives ip addresses and filenames
07:11
and tftp gives kernels
07:12
<prpplague>
i would suspect you are probably using pxe as the boot method
07:12Envite has quit IRC
07:14Envite has joined #ltsp
07:15
<Envite>
sorry: my laptop battery went out without advertising
07:15
<prpplague>
Envite: np, pxe will use the dhcp server
07:16
Envite: but pxe is the actual boot method
07:16
Envite: so if you have a dhcp server configured then you would set the hostname in that config
07:16
<Envite>
ok, I'll see, thx
07:20
http://pastebot.ltsp.org does not seem to work
07:21
well, i fixed it

morning all
08:57
<pipedream>
afternoon :-P
09:01
<pscheie>
What? You mean it's not 9am for everyone on the planet? Some people need to get their clocks fixed. ;-)
09:02
Okay, so is anyone running LTSP servers with 20-25 clients using a single PATA drive in the server?
09:02
Successfully?
09:03
There were messages on the K12LTSP list a few years ago from people who had major performance dropoffs when they got past 10 clients.
09:03
The consensus was that IDE didn't do well past 10 clients.
09:04
But now I've heard that 'some people' do run more than 10 clients with PATA.
09:04
<ogra>
a few years ago PATA drives were a lot slower ...
09:04
<pscheie>
The IDE spec obviously hasn't stood still in the intervening years.
09:05
Right, 4500rpm instead of 7200rpm
09:05
and nowadays they have at least 8MB cache
09:06
So, is it safe to try to run a classroom server with 15-20 clients using PATA nowadays?
09:06
I'll be the answer is 'it depends'!
09:07
<ogra>
right ...
09:07
to be sure i'd use two PATA disks and software raid in striping mode ;)
09:08
<pscheie>
Two drives breaks my budget :-(
09:08
...or perhaps not, now that I think about it.
09:10
The budget for the box is $600. For that I can get a standard box from a local vendor, with 1GB RAM and a PATA drive
09:10
It needs to support =<10 clients, which it should with no problem.
09:11
<ogra>
well, depends on your desktop ... 1G is quite small for KDE or gnome
09:11

09:11
<Gadi>
!seen jammcq_laptop
09:11
<ltspbot>
Gadi: jammcq_laptop was last seen in #ltsp 6 weeks, 0 days, 19 hours, 53 minutes, and 9 seconds ago: <jammcq_laptop> find it on your server, and copy it to /opt/ltsp/i386/bin
09:11
<pscheie>
But if the teacher wants to add more clients, I'd like it to be just a matter of adding hardware, not replacing
09:11
morning Gadi
09:11HumanPrototype has quit IRC
09:12
<Gadi>
ok, which one of you kidnapped jammcq?
09:12
<ogra>
pscheie, you need ~128M per client on the server for a gnome/KDE setup .... ~64M for xfce ... less for smaller desktops like openbox etc
09:12
<Gadi>
pscheie: I still have a star next to your email to remind me to update that audiolist-alsa file ;)
09:13
perhaps it'll be my New Year's resolution
09:13
<pscheie>
Gadi, what's the most number of clients you've run on a single PATA disk?
09:13
<Gadi>
hmm... most of our clients have scsi boxes
09:13
specifically PATA or SATA in general?
09:14
<pscheie>
Yeah, scsi would be nice, but it's more than my budget allows right now
09:14
PATA
09:14
<Gadi>
hmm... even tougher question
09:14
which drivers are you using?
09:14
<pscheie>
We got an HP Pavillion with SATA for a classroom pilot but while FC5 installs, it hangs at boot
09:14
<Gadi>
SATA's another case where ubuntu's udev system cant make up its mind ;)
09:15
<ogra>
did you try edgy ?
09:15
<Gadi>
pscheie: yeah, thats a driver issue
09:15
<pscheie>
Not yet. I really wanted to stick with K12LTSP 5 just to make the install easier for the school techs
09:15
<Gadi>
ogra: just 'zinging' you a bit, since i know ur listening ;)
09:16
<pscheie>
We have a demo for the teachers tomorrow. We'll probably just use one of my test boxes for it.
09:16
<ogra>
Gadi, :P
09:16
:)
09:16
<Gadi>
nobody in ubuntu has gotten around to fixing the Adaptec Zero-channel raid bug I posted back in early dapper days (that persists in edgy)
09:17
<pscheie>
It's got a PATA disk, and running eight clients w/Gnome was no problem.
09:17
<ogra>
well, we're looking for kernel devs, if you know someone ;)
09:17
<Gadi>
:P
09:17
somehow, there are 2 conflicting drivers for RAID, 2 for SATA, ....
09:17
cant we all just get along?
09:18
pscheie: on the working system, when you run lsmod, is it using ide_generic?
09:19
and ide-disk and such?
09:19
or is it using ata_piix and friends?
09:19
<pscheie>
I can't remember, and I'm not a the box at the moment. ide_generic doesn't ring a bell though
09:19
I think it was ata_piix
09:19
<Gadi>
does it come up as /dev/hda?
09:20
or /dev/sda?
09:20
<pscheie>
/dev/sda, at least in rescue mode.
09:20
That's the problem, it hangs when it says it's probing ide0
09:21
<Gadi>
there ya go
09:21
<pscheie>
We tried turning off all the PATA pieces in the bios, but the kernel still probes 'em
09:21
<Gadi>
conflicting drivers
09:21
nah, you need to blacklist drivers
09:21
in /etc/modprobe.d/blacklist
09:21
(on Ubuntu)
09:21
prolly similar in redhat
09:21
<pscheie>
so, something I can pass to GRUB to test?
09:22HumanPrototype has joined #ltsp
09:22
<Gadi>
or, alternatively, you can change grub to boot off of /dev/hda1
09:22
that should get you most of the way (tho, you prolly need to modify /etc/fstab as well)
09:23
see, the problem is the wrong driver gets loaded first on boot
09:23
so, the second driver (the correcct one) is told that the first one owns the device
09:23
but the first one created /dev/hda, while the second wants to create /dev/sda
09:24
and the second is the one that was used in the installer
09:25jammcq has joined #ltsp
09:25
<pscheie>
ah, that makes sense. Why does the installer figure it out but not the completed install?
09:25
<Gadi>
heh, or vice versa
09:25
I have no idea
09:25
<jammcq>
g'morning
09:25
<Gadi>
but its the same issues
09:25
<pscheie>
linux rescue also figures it out.

09:26
<ogra>
strange, what happened ? i just noticed that he vanished recently
09:26
(including blog and website)
09:26
<jammcq>
he got pissed cuz things weren't working for him
09:27
<ogra>
hrm ...
09:27
<jammcq>
I think he just had a bad day
09:27
<ogra>
i hope he comes back ... tell him he's missed
09:27
<jammcq>
i'm asking him on jabber now
09:28

btw, i got a working lts.conf parser for the thin-client-configurator ready ... ;)

09:32
jammcq: finally moving back on december 28th
09:32
jammcq: we ran into a small snag on donna's visa
09:32
<jammcq>
oh? did you get it fixed?
09:32
<prpplague>
jammcq: hopefully get that taken care of soon
09:32
<jammcq>
moving to where? Dallas?
09:33
<prpplague>
jammcq: one of the entry stamps in her passport is smudged, they can't read the dates, so they have to verify the info with DHS
09:33
jammcq: yea, back to big D

Gadi: is ide_generic the PATA driver? that is, will blacklisting that stop it from grabbing the device?
09:49
I think the SATA driver is sata_nv
10:00MoL0ToV has quit IRC

<Gadi>
pscheie: are there any IDE hard drives/CDROMs/other devices or only the PATA?
10:05
<pscheie>
Gadi: There is a DVD/CD drive on the PATA, but we don't need that (aside from during install)
10:05
I *think* the tech tried disconnecting it
10:06
<Gadi>
then, it is prolly safe to blacklist ide-disk and ide-generic
10:06
<pscheie>
Ok, we'll try those. Thanks.
10:07
<Gadi>
otherwise, you can try not blacklisting anything, and changing the devices in menu.lst and fstab
10:11
<pscheie>
I think grub.conf points to (hd0,0)/dev/some-volume-group/some-logical-volume for /
10:11
and...I can't remember what fstab points to.

video=nofb ??
11:08
no idea, really ... i can just guess
11:13

gadi, afai "nofb" is a boot option itself
11:13
not a video option to lilo
11:13
so append just nofb rather than "video=nofb"

or adduser
12:32
depending...
12:32

edubuntu
12:32

uses IRC commands
12:35

12:39
ah, i see
12:47
vagrantc, whats that strange split of update-inetd into a separate package in debian ?
