Hello, is it possible for ltsp clients to use the swap *file* from a local linux installation, instead of a swap partition?
03:37
<johnny>
yes.. USE_LOCAL_SWAP or something
03:37
err
03:37
wait
03:37
sorry.. perhaps not, but seems not to hard
03:37
thought i saw you wanted local vs remote.. not file vs partition
03:38
<alkisg>
johnny hi, yeah, it probably means patching some init scripts
03:38
<johnny>
yeah.. but not too difficutl
03:38
<alkisg>
So you think it can be done? I'm not looking for *how* it is done now, just the possibility, to format the clients in one partition instead of two... (small disks)
03:38
<johnny>
just edit your distro's config files.. i think there is even some relatively common stuff
03:39
<alkisg>
johnny, ubuntu 8.04.1
03:39
<johnny>
yeah.. it shouldn't be that hard.. just see how USE_LOCAL_SWAP does
03:40
then you'd talk to the folks here in a few hours and ask them what syntax should be for lts.conf
03:40
<alkisg>
how is the swap file usually named? /swapfile?
03:40
<johnny>
uhmm? swap files are a rarity.. i don't think there is any general name
03:40
generic*
03:41
you'd prolly just pass the path
03:41
<alkisg>
hm... ok, I was looking to named it in a standard way. I thought with kernel 2.6 swap files are as fast as swap partitions, so more people would use them... anyway! :)
03:41
<johnny>
old habits die hard i gues
03:42
<alkisg>
heh... yeah! I think that about mailing lists vs forums! ;)
03:42
<lejo>
not having to swap is even better ;-)
03:43
<alkisg>
Well, with ltsp, local apps and 128 RAM I don't think I can avoid it!!!
03:43
<johnny>
forums kinda suck tho
03:43
you could use nbd swap too ...
03:43
<alkisg>
It's the people (in the forums), not the layout that makes the content...
03:43
<johnny>
sure.. but i hate having to go to their site
03:43
with email.. i have it all in one place
03:44
now.. if somebody made forum software on top of nntp...
03:44
or imap
03:44
<alkisg>
nbd is automatically used, but I think that local swap (even with ancient hard drives) would be faster... I have just a humble 100mbps network...
03:44
<johnny>
then you could subscribe to it
03:44
and then folks coudl use the web interface if they wanted.. and i can bookmark and keep certain posts for my own searching.. and reply directly from within an interface i am familiar with
03:45
<alkisg>
To be honest, I'd prefer a wikipedia-style forum (not bbcode), with email integration (send/receive), not only rss...
03:45
<johnny>
email on it's own is kinda lame tho.. since you can't easily get the archive of older stuff
03:45
if you used imap.. you get all that for free
03:45
<alkisg>
And the hierarchy of forums beats mail clients... Also access lists (security/hidden boards), banning etc... the "new stuff"
03:46
<johnny>
sure.. but you can do that with imap
03:46
<alkisg>
Imap is good, but imap clients suck! :)
03:46
...and servers!
03:46
<johnny>
i'm pretty happy with dovecot so far
03:46
<alkisg>
e.g. gmail / evolution / thunderbird
03:46
<johnny>
evo is ok enough
03:46
a bit slow
03:46
<alkisg>
claws / mutt / dovecot is good, but not for the average joe...
03:46
<johnny>
average joe doesn't need a server :)
03:47
average joe can use the web interface
03:47
altho they are missing all the lovely bits of keeping the sites they like all together in one place
03:47
currently i'm using evo + evolution-rss for rss feeds
03:47
<alkisg>
I tried to install dovecot to transfer my mails from outlook to evolution: uploading 20000 mails never finished, so I used thunderbird for the migration... :(
03:47
<johnny>
why would you do that? can't you just import directly?
03:47
<alkisg>
(outlook fault, not dovecot)
03:48
<johnny>
without setting up any server
03:48
<alkisg>
Headers lost, charset mismatches etc
03:48
<johnny>
thunderbird did do a good job with my outlook conversion tho
03:48
but i didn't have a large or insane mailbox at teh time
03:48
<alkisg>
Thunderbird uses windows MAPI to get the mails, and it's the best route I've seen so far, but it corrupts some headers
03:48
<johnny>
that was when i was still using windows
03:48
aha..
03:49
so i got lucky
03:49
shortly after .. i migrated to linux
03:49
<alkisg>
Well, you're in us, I'm in greece, charset support sucks! :P
03:49
<johnny>
:(
03:49
<alkisg>
I've migrated since 5 months now, I don't think I'll ever go back
03:50
I don't miss anything, just having some problems exchanging silly .doc format...
03:51
<johnny>
been quite some years for me now..
03:51
wow..
03:51
6 years now
03:52
where does the time go..
03:52
<alkisg>
Heh... how time goes by...
03:52
I'm just sorry for the 15+ years I invested learning windows api programming!

03:53
<johnny>
well you missed alot of nastiness
03:53
things have evolved really quickly on the last few years
03:53
before that.. not so good
03:53
<alkisg>
I've seen debian 4 gears ago, and ubuntu this year, I was amazed by the changes (not dut to ubuntu of course, the whole thing)
03:53
/dut/due
03:54
And greek support is fine... Not long ago we would have to spend a week to get greek character set everywhere
03:54
...the joy of utf8!
03:55
<johnny>
well good :)

What I really miss is a "how to contribute" for newbies, but *not* for a specific distro

E.g. I want to insert greek characters (with fontforge) in tahoma for wine and I'm using ubuntu, I really don't know where I should ask for this to go upstream... :)
03:58
Anyway johnny thanks for your help! Bye...

<djacidjac>
hi, newbie here. trying to get ltsp working with one server and one client. the server has only one NIC and I'm not connected to the internet. I have a router handy if i need it. I have looked for hours but I do not know how to configure the server NIC. Any suggestions?
03:59
<alkisg>
Which distro?
03:59
<djacidjac>
ubuntu 8
04:00
<Ryan52>
djacidjac: 8 what?
04:00
<alkisg>
ok, you want to be able to see internet?
04:00
<johnny>
the problems are so different , it's hard to make a generic how to contribute how to, that is anything more than basic common sense
04:00
<Ryan52>
nevermind, I doubt anybody is using intrepid yet.
04:02
<alkisg>
djacidjac, I got to go, so very quickly to get you started: put static ip 192.168.0.1, sudo dhcp-reconfigure dhcp3-server => listen on eth0, reset (to restart dhcp) and you should be good to go.
04:02
<djacidjac>
ok, thx
04:03ogra has joined #ltsp

ogra hi, just a yes/no answer (not a how to), is it possible for ltsp clients to use a local swap *file* (not partition)?
04:09
anyway, got to go, bye everyone.
04:17
<djacidjac>
alkisg, if you havn't left yet, to set my static ip; what should broadcast and gateway be set to? sorry to ask, but i need to.
04:17gate_keeper__ has quit IRC
04:29alkisg has quit IRC
04:29
<djacidjac>
can anyone point me to a comprehensive resource on how to successfully set my NIC to a satic IP?
04:35
<johnny>
djacidjac, sure.. ubuntu has nice docs i imagine
04:35
there's probably even a GUI
04:35
i just edited the file /etc/network/interfaces, but you would probably want to read about that file before editing it directly.. the GUI tools are just too slow for me
04:35
<djacidjac>
well i've been looking and i can't seem to get any nic network settings to work.
04:37
<johnny>
did you try lookingfor a gui under the administration menu for network settings/
04:37
<djacidjac>
i have a few basic questions actually. maybe you could shed some light on for me; do i need to use a router if i only want one client? -could i plug each computers nic into the other directly?
04:37
<johnny>
sure.. but you won't get any internet
04:37
<djacidjac>
would a gui auto-fill the info i don't know such as "broadcast" and "gateway"
04:38
<johnny>
you can leave them default in 99% of cases
04:38
<djacidjac>
I don't want any internet. i'm just trying to get this to work as simply as possible first.
04:38
<johnny>
and you might need a crossover cable..
04:38
depends on if your network cards can sense them or not.. many newer ones can, but i don't know about yours
04:39
<djacidjac>
I can file-share with a standard cable. does that indicate that i don't need a crossover cable for ltsp?
04:39
<johnny>
probably
04:43
<djacidjac>
i'm about to look for a gui, gotta fix my /network first.
04:47
any idea what "gateway" affects if i have no router and no internet connection?
04:49
<johnny>
not much

quick question: how do I shut off logging in Fedora? specifically, There's a lot of lines in the messages log.
08:25
they look like this: xinetd[2377]: EXIT: ldminfod status=0 pid=5160 duration0(sec)
08:26
They occur about every second per client.

<bitplex>
yeh, but i want the user to see his or hers desktop upon login to any computer on the network.
09:23
<_UsUrPeR_>
bitplex: I think that was a primary advantage of MS Active Directory
09:25
<bitplex>
so active directory is my only option?
09:25
<etyack>
bitplex: you could run puppy linux or some other small linux disto then use vnc or nx to connect to a Linux server.
09:26
are you looking for session persistence?
09:28
<bitplex>
i think so
09:28
<etyack>
nx/freenx offers session persistence
09:28
<bitplex>
do you need a windows machine to get active directory?
09:28
<cyberorg>
bitplex, http://en.opensuse.org/LTSP/USB_Quickstart and http://en.opensuse.org/LTSP/CD_Quickstart
09:28
<etyack>
you don't need active directory
09:29
why not use ltsp?
09:30
<cyberorg>
bitplex, you can also use nis, or setup ldap authentication that gives "roaming profile"
09:31daduke has quit IRC
09:31
<bitplex>
because wont that load the os from the server? I just want the user to login into a computer and have access to their files from any machine. Each with ubuntu installed.
09:32
<cyberorg>
bitplex, use nis or ldap auth

stgraber hi, could you help me a little with an authentication problem? italc 1.0.9 with ubuntu 8.04.1 / ltsp...
11:23japerry has joined #ltsp
11:23
<alkisg>
I generated the keys (twice to be sure) but I get a message from ica that a client tried to authenticate but... so I can't use demo mode
11:24
It look like it can't authenticate in 127.0.0.1, should I change ica-launcher to use 192.168.0.1?
11:25
/ica-launcher/italc-launcher/
11:28
stgraber, and when running ica from command line, I get (when I try demo mode): [warning] demoServer::updaterThread::run(): could not connect to local IVS! [critical] isdConnection::authAgainstServer(): unknown sec-type for authentication: 2

<_UsUrPeR_>
hey, can anyone suggest to me the best way to get a client with dual-head capabilities to work properly with a DVI output instead of the vga output in Fedora? I have gotten it to work in ubuntu with the command #X_OPTION_01 = "\"ForcePanel\" \"True\""
11:33
<warren>
_UsUrPeR_: fedora LTSP doesn't support the X_* options from lts.conf except X_CONF which you can use to specify an alternate xorg.conf
11:33
I suppose I should work on that roblem...
11:34
_UsUrPeR_: X_CONF can work like this: you drop an xorg.conf in your chroot in some other location like /etc/X11/awesome-xorg.conf and X_CONF=/etc/X11/awesome-xorg.conf
11:35
sigh, I guess I have to work on adding support for those options.
11:35
it is difficult because I can't use the configure-x.sh

warren: etyack claims that it's possible, but we have not gotten to testing it out yet.
11:38
<warren>
does that work in ubuntu LTSP now?
11:38
<etyack>
_UsUrPeR_: let's be accurate here
11:38
<_UsUrPeR_>
etyack: woah there :)
11:38
<etyack>
my method is to create a custom xorg.conf
11:38
<warren>
I managed to avoid configure-x.sh for keyboard layout
11:38
but it seems I wont be able to avoid it for options like this
11:39
etyack: you use X_CONF to point at that custom xorg.conf?
11:39
<etyack>
i do not believe there is a method to handle dual monitors w/o creating a custom xorg.conf in ubuntu
11:39
warren: yes
11:39
<warren>
ok

i have not tested this yet, but it is the path I plan to go down

12:07

warren: it is generating a lot of syslog messages on one clients servers, the one with the problematic sis chipset. probably because ldm is attempting to start so many times.
12:08
warren: i modified the logging in ldminfod xinetd to stop for now
12:08

12:23
<warren>
I often see ldm crash once before it works
12:23
<vagrantc>
warren: to catch when ldm keeps respawning too much
12:23
<warren>
i'm not sure why
12:23
<vagrantc>
weird.
12:24
<warren>
vagrantc: if it crashes 5 times in a row within a short amount of time we should't respawn at all
12:24
<vagrantc>
oh, i figured out how to get rsyslog handling remote syslogging ... i think the first time i tried it wasn't working client-side.
12:24
<warren>
vagrantc: display an error message instead
12:24
<vagrantc>
warren: well, sure.
12:24
in rsyslog.conf: #$ModLoad imudp
12:24
#$UDPServerRun 514
12:25
it seems to be absurdly slow in catching logs, though.
12:26alkisg has joined #ltsp
12:26
<vagrantc>
like it only displays one line at a time, so a client booting up sending all it's kernel messages can take a while to really kick in... haven't tried with lots of clients or using rsyslog's other remote syslogging methods

but i thought the whole reason to specify distro-specific stuff was to figure out what we could safely ignore...
12:33
i attempted to prefix it with "minor comment" and "not a big deal" for a reason, though.
12:33

vagrantc: oh, in the case of 905 that was John's mistake.
12:33

ah, fair enough, labeled as such.

<warren>
I did notice that one
12:34Q-FUNK has joined #ltsp
12:34
<vagrantc>
warren: if you really want me to specify others, i could, but that would feel like nit-picking ...
12:37
<ogra>
cyberorg, proposing ltsp 4.x to users on the mailinglist is pretty risky, you should at leat point out that there were no security upstaed since ober a year
12:37
*updates
12:37
*over
12:37
*sigh*
12:38* ogra thinks he typed to much on onscreen keyboards today
12:38
<warren>
over a year? hasn't it been several years?
12:38
<ogra>
well, i'm at least sure for the last year
12:38
:)
12:38
might even be two
12:38
i know jammcq did at least a kernel update once
12:39
but X is indeed totally out of discussion, that wasnt updated at all
12:39* Q-FUNK wonders if LTSP can be summarized as one guy named: oliver "vagrant" togami?
12:39
<vagrantc>
pretty sure nothing since 2006
12:39
<ogra>
right
12:39
Q-FUNK, lol
12:40
Q-FUNK, well,most credit for the code changes over the last 8 months or so rather goes to vagrant and warren
12:40
<Q-FUNK>
in both cases, for porting the code to non-buntu distros?
12:40
<vagrantc>
well, i did that withing weeks of having anything from ubuntu
12:40
<ogra>
i only gave good or bad input on their code
12:40
<vagrantc>
and the first ltsp muekow distro was actually debian-based (skolelinux) rather than ubuntu
12:41
<ogra>
not true
12:41
<vagrantc>
by like 2 weeks or something
12:41
<ogra>
nah, breezy was first
12:41
really
12:41
<Q-FUNK>
it has to be said that a thincan works very well on skolelinux, despite their old codebase
12:41
<vagrantc>
ogra: i'm pretty certain skolelinux's sarge-base release came out before breezy.
12:41
<ogra>
it likely works well on edgy or older as well :)
12:41
vagrantc, with ltsp5 ?
12:42
<vagrantc>
ogra: with muekow
12:42
<ogra>
hmm
12:42
<Q-FUNK>
muekow???
12:42
<vagrantc>
ogra: we didn't yet have the confidence to call it ltsp5
12:42
<ogra>
but with the self hacked petter muecow :)
12:42
<vagrantc>
ogra: it was backported from unstable ...
12:42* ogra yippies ... finally my ubuntu-mobile desktop works
12:43
<ogra>
oh
12:43
i thought it was the hacked up variant he had documented on the ltsp wiki
12:43
<vagrantc>
i jumped on debian-ifying the ltsp stuff within days of mdz releasing any code to any of the lists i was on.
12:45* ogra goes back to hack on his hal-touchscreen-config backend
12:46
<ogra>
vagrantc, did you tast xorg with hal input on ltsp already ?
12:46
*test
12:46
its quite awesome ...
12:46
<vagrantc>
ogra: don't have any idea how to do so
12:47
<ogra>
but we'll need a lot of hal-set-property hacking soon for setting input properties if we want to do it properly
12:47
<vagrantc>
i just generally do whatever debian does, and report bugs when things don't work for LTSP
12:47
<ogra>
i thought it was n sid already
12:47* ogra thought ubuntu puled much of it from there
12:48
<vagrantc>
xorg 7.3 in unstable ...
12:48
7.4~1 in experimental
12:49
<ogra>
ah
12:49
you should build from experimental :)
12:49
its cool
12:49
only needs /etc/default/console-setup nowadays for all keyboard stuff

yeah, it's still the old REMOTECMD in the docs.

So my plan is to drop a script in LTSP_ROOT/usr/lib/ldm/rc.d and have it run a 'mount -tnfs remote:/home/${USER} /home/${USER}' on the server through the LDM_SOCKET. I'm guessing that the timing of this is pretty delicate. Am I on the right track?
14:28
<vagrantc>
Blinny: each user will need to have permission to mount their own home directory
14:28
<ogra>
it wont work
14:28
<etyack>
what about using pammount?
14:28
<warren>
and that will conflict with the sshfs mount that is default now
14:28
<ogra>
right, thats the right way
14:28
the rc.d scripts are executed between the two ssh calls
14:28
<vagrantc>
i thought there were issues with pammount and ssh
14:29

the first one lready needs a homedir

Ooooh, bad patch.
16:13
yikes.
16:13
<warren>
gbolte: unclear if we fixed it in a different way
16:13
sbalneav: ?
16:13
<gbolte>
ah
16:13
<sbalneav>
It chowns the media directory in media to the user.
16:14
Now the user owns the directory.
16:14
<gbolte>
sbalneav, the user owns their own directory within media
16:14
<sbalneav>
and can fill it up with whatever s/he likes
16:14
<warren>
sbalneav: the bad patch was where?
16:15
<sbalneav>
Right, but they shouldn't. The dir should be root owned, then when the mount occurs, it takes on the ownership of the user.
16:15
Otherwise, you've got a directory in / that a user can write to.
16:15
<warren>
sbalneav: I thought I dealt with this the correct way
16:15* warren checking
16:16
<sbalneav>
The reason why I'm pointing this out is: this is the way I handled it the first version of lbmount, chowning the home dir.
16:16
and I got my wrist slapped by mpitt :)
16:16
It was apparently felt to be a HUGE security hole.
16:17
<warren>
sbalneav: wait, I'm trying to understand what you're saying
16:17
sbalneav: what patch specifically?
16:17
<sbalneav>
the lbmount patch that gbolte supplied.
16:17
pointed to, etc.
16:17
<gbolte>
sbalneav, I dont see how ours is bad...it creates the dir in media mounts the device to that folder then upon unmount deletes the folder
16:17
<sbalneav>
in the bug report.
16:17
gbolte: ok, here's how it was explained to me.
16:18
1) security concious admin has /tmp as a separate mount point. Therefore, no user should be able to write in /
16:18
2) User plugs in stick
16:19
3) user MANUALLY umounts the /media/user dir
16:19
4) user madly scriblles in /media/user (in /) thus filling it up
16:19
That was how it was described to me.
16:20
<gbolte>
sbalneav, what stops the user from filling /tmp
16:20
<sbalneav>
Nothing, but see point 1, /tmp's a separate partition.
16:20
<gbolte>
lol once tmp is full nobody can mount
16:20
so

16:21

fo all other users it was fixed in 8.04.1

so we should create a separate part for /media and all is well

16:24japerry has joined #ltsp
16:24
<ogra>
warren, right
16:24
<japerry>
heh
16:24
did I miss anything? ;-)
16:25
<sbalneav>
ok, heading home for the day, be on tonight.
16:25
afk
16:25
<ogra>
warren, but i'm happy with what we have
16:25
<japerry>
what should happen is that lbmount puts the devices in .gvfs
16:25
<ogra>
warren, and rely on pitti fixing it properly at some point
16:25
no
16:25
<japerry>
why are user devices being put in /media?
16:25
<ogra>
then you cant use the devices in i.e. openbox
16:26
ltsp isnt gnome standalone
16:26
nor KDE
16:26
<warren>
ogra: you are not using http://devzilla.novell.com/kiwi-ltsp/show_bug.cgi?id=10 right?
16:26
<ogra>
xfce doesnt use gvfs
16:26
nor does blackbox, icewm, openbox
16:26
<japerry>
.gvfs is just a folder. it could be ~/.ltspmounts for all I care
16:26
<ogra>
warren, i use what upstream fixed
16:27
warren, 1:1 the patch we all worked on as a team
16:27
which is considered the right fix by my security team and works on all WMs
16:28
<warren>
ogra: why are 8.04 users and fedora users complaining of seeing devices of other users on their desktop?
16:28
<gbolte>
lol and gentoo evidently
16:28
<johnny>
my issue is not on gentoo
16:28
it's on ubuntu
16:28
<gbolte>
oh
16:28
ok
16:28
<johnny>
gbolte, i deploy ltsp on ubuntu atm
16:28
<ogra>
warren, if users broke the group setup it wont work
16:28
<gbolte>
johnny, I see
16:28
<warren>
ogra: "it" being what?
16:28
<johnny>
i just happen to use gentoo for my own stuff, and wnated to help
16:29
<ogra>
the hiding
16:29
<gbolte>
fair enough johnny
16:29
<johnny>
my users are all in a terminals group, plus all the normal groups
16:29
<ogra>
johnny, see my last coment on the ubuntu bug
16:29
<vagrantc>
warren: do they have a setup where all users are in the same group?
16:29mhterres has quit IRC
16:29
<johnny>
ogra, link me?
16:29
<ogra>
i did above :p
16:30
<warren>
vagrantc: oh, i see
16:30
<ogra>
https://bugs.launchpad.net/ubuntu/+source/ltspfs/+bug/210379
16:30
see my last comment there
16:30
it breaks for admins who dont use the debian/ubuntu default group schemeing
16:30
they may be all in the same group, thats fine
16:31
but need to have the default group (which is ogra for the ogra user here for example)
16:31
ldap admins often miss to set that up
16:31
<johnny>
hmm.. no ldap here..
16:31
<ogra>
tht breaks it again
16:31
<johnny>
but ok
16:31
i'll take a lok
16:31
<ogra>
johnny, well, are you up to date ?
16:31
<johnny>
yes
16:31
<ogra>
with the glib package from hardy-updates ?
16:32
<johnny>
in the chroot?
16:32
<ogra>
or installed from an 8.04.1 cd
16:32
no
16:32
<johnny>
then yes
16:32
<ogra>
its all server side
16:32
<gbolte>
ogra, so in order for it to work properly users need to be in their own group?
16:32
<johnny>
i just used the gui to create the users
16:32
<ogra>
right, hich is a default requirement on ubuntu and debian
16:33
<gbolte>
what about if you are using eDirectory
16:33
<ogra>
and which is a clear thing if you read the patch warren did
16:33
<japerry>
or AD
16:33
<warren>
I barely remember doing it
16:33
<johnny>
i have to run to work.. where my ltsp install is
16:33
maybe you'll still be here :)
16:33
<ogra>
warren,
16:33
- if (mkdir(dir, 0755)) {
16:33
+ if (mkdir(dir, 0750)) {
16:34
i wont, have to do work as well, feature freeze on thursday ...
16:34* ogra is actually not here ...
16:34
<vagrantc>
warren: ltspfs-trunk 54
16:35
<warren>
I know I did it
16:35
but I don't remember it
16:35
<vagrantc>
heh
16:35
<johnny>
i wonder if there will be a backport of ssh 5.1 and sshfs 2.1 for ubuntu
16:35
that way i can install ltsp and test local apps more easily..
16:36
<warren>
oh
16:36
0700 doesn't work because the non-root user still has to access inside.
16:36
0770 is undesirable because we don't want the non-root user to be able to write arbitrary things in there.
16:36
(/media/$username is owned by root and managed by lbmount, while mounts inside that are owned by the user.)
16:36
0750 is thus desirable by process of elimination.
16:36
<vagrantc>
debian lenny has openssh-5.1 and sshfs-fuse 2.0 has an RC bug allegedly fixed in 2.1 ... which means lenny will either get sshfs 2.1 or no sshfs at all, likely.
16:36johnny has left #ltsp
16:38
<ogra>
warren, 700 cant work because lbmount is suid root
16:38
oh, right, i missed the brackets
16:38
:;)
