hi all
05:11
jammcq, there?
05:13
does someone know something about beowulf clustering and LTSP?
05:13
<vagrantc>
using LTSP for beowolf clusters?
05:13
<ogra>
heh ... nice
05:14
vagrantc, still up ? or already ?
05:14
<vagrantc>
ogra: still up, yes. :)
05:14
<ogra>
crazy guy :)
05:14
<vagrantc>
ogra: someone in india has been using simple-cdd (a debian-cd wrapper) and i've been helping them
05:15
and fxing bugs all along the way
05:15
<ogra>
nice
05:15
i'll have to dig into dbein-cd as well soon :(
05:15
<vagrantc>
vykarian: you'll have to convince ogra to accept my future patches to split ltsp-client
05:15
<ogra>
*debian (indeed)
05:16
<vagrantc>
vykarian: otherwise you'll have X running on your beowulf nodes.
05:16
debian-cd is evil.
05:16
there should be a massive campaign to rewrite it.
05:16
<ogra>
vagrantc, i still dont understand why you want to split the -client and not the -server since you talk about ltsp-build-client
05:16
<vagrantc>
ogra: i want to split both
05:16
<ogra>
aha, thats not what you said yesterday
05:17
and thats what confused me
05:17
<vagrantc>
ogra: it's maybe not what you saw ... and i didn't clarify it.
05:17
or, didn't clarify well enough ...
05:17
<ogra>
("i want to split ltsp-client to have ltsp-build-client separated")
05:17
<vagrantc>
i think that was a typo.
05:17
<ogra>
ah
05:17
<vagrantc>
one typo leads to days of confusion!
05:17
<ogra>
heh
05:17
well, sorted
05:18
<vagrantc>
hopefully.
05:18
ogra: so now, with some sleep behind you, and some clarification, what do you think? :)
05:18
<ogra>
so whats in -server-core then, only ltsp-build-client and the plugins ?
05:19
i guess the other one would be ltsp-server-services (hmm, bad name) and a meta ltsp-server
05:19
<vagrantc>
yeah, probably just ltsp-build-client + plugins ... maybe not all of the plugins (like the stuff that copies the files to the tftp dir)
05:19
if it weren't for the ltsp-client-builder .udeb, i would probably just call it ltsp-build-client
05:21
<ogra>
what i'm fearing a bit is that every split will make it more complicated for other distros to grasp muecow
05:21
<vagrantc>
and then, i think ltsp-client-core, would just be the barebones what you need to handle read-only NFS root, with hooks for custom scripts ... and then ltsp-client would plug in everything into those hooks.
05:21gigabytes has joined #ltsp
05:22
<ogra>
the initial implementation was very easy to understand, the plugins already make it complicated ... now we even split it up and you need to understand debian packaging
05:22
<vagrantc>
ogra: well, i think i would be (ostly) satisfied with one more split. and i really think we should consider dropping ltsp-server-standalone ...
05:23
<ogra>
how would you do the dhcp config then ?
05:23
i mean you will still need to do the same we do currently
05:23
<vagrantc>
recommends on dhcp3-server , install the file the same way ...
05:23
<ogra>
you just move oit around to somewhere else
05:23
ltsp-server already has the recommends
05:24
<vagrantc>
ah great, even smaller diff :)
05:24
<ogra>
-standalone has the dependency that makes sure it really gets installed
05:24
thats the only purpose of -standalone
05:24
<vagrantc>
yeah ... and it just doesn't seem like it should warrant a whole package for something that fits the textbook definition of recommends.
05:24
<ogra>
well
05:24
its a metapackage
05:25
<vagrantc>
we should shove more stuff into it, then.
05:25
more dependencies!
05:25
<ogra>
yeah, thats what i wanted
05:25
nah
05:25
but more settings ...
05:25
<vagrantc>
well, at any rate ...
05:25
<ogra>
i.e. syslog and a syslog config
05:26
(one that sets up default remote logging)
05:26* vagrantc realized syslog handling is broken by the RC whitelisting stuff
05:26
<ogra>
not in edgy
05:26
i whitelisted syslog and klog in ubuntu
05:27
<vagrantc>
oh. well isn't that simple.
05:27
<ogra>
and in edubuntu i even install a syslog setup that logs by default to the server
05:27
wroks properly
05:28
<vagrantc>
i still probably have time to fix syslogging in etch...
05:29
<ogra>
for the client i think about finally using the not yet existing ubuntu-thin-client package
05:29
<vagrantc>
i also might fix the boolean handling :)
05:29
(for the shell scripts)
05:29
<ogra>
i know jammcq would like to get the term ltsp out of the face of the users ... that should be a first steop
05:30
<vagrantc>
???
05:30
<ogra>
we discussed it in mountainview
05:30
<vagrantc>
i don't have any idea what you mean
05:30
<ogra>
ltsp is not a term all admins will know, whereas they can imagine something under "thin client"
05:30
<vagrantc>
ah!
05:31
<ogra>
so jammcq wants to replace ltsp with thin client where possible
05:31
<vagrantc>
got it.
05:31
<ogra>
i.e. ltsp-manager will be called thin-client-configurator in the future
05:31
so we should think about the naming scheme for the metapackages with that in mind
05:32
<vagrantc>
i'm amenable.
05:32
<ogra>
the low level packages can still be ltsp-something ...
05:32
<vagrantc>
though other thin-client implementations might want that.
05:32
<ogra>
which ones ?
05:33
ubuntu doesnt have any others packaged
05:33
who comes first gets served first ;)
05:33
<vagrantc>
well, sure.
05:33
it's mostly a "don't grab too generic a name to prevent namespace clash" sort of philosophy ...
05:34
<ogra>
sure
05:34
<vagrantc>
of course, with ubuntu, you're much more free to select a given application as THE ubuntu choice.
05:34
<ogra>
but for me personally its very unlikely that we will get a different thin client solution into ubuntu main
05:35
so the "*ubuntu*-thin-client" package will provide what we support
05:35
<vagrantc>
right.
05:35
<ogra>
debian is lacking the "no duplication in main" policy here :)
05:35
<vagrantc>
exactly.
05:36
<ogra>
that keeps me safe in ubuntu :)
05:36
if you still have so much time before etch, you should get jetpipe in to not lack printing
05:37
<vagrantc>
i think that's a new feature
05:37
<ogra>
well
05:37
its a code replacement
05:37
<vagrantc>
code that's been removed from debian for months
05:38
<ogra>
but you probably wheer to fast with ripping lp_server out so the RM tream might see it like new
05:38
*were
05:38
<vagrantc>
i was called out on copyright issues.
05:38
<ogra>
yeah, i know
05:39
well, i think i'll make a separate package for it ... so you can at least backport it ... (which indeed doesnt give you the needed hooks in ltsp)
05:39
<vagrantc>
so, rather than getting ltsp removed entirely, i removed the violating code.
05:40
ogra: we can add custom hooks using RC scripts or something ...
05:40
<ogra>
(even though its maintenance sillyness to keep 50 lines of code in a separate package)
05:40
<vagrantc>
RCFILE_NN
05:41
ogra: yeah, or even 0 lines of code :P
05:41
<ogra>
well, 0 lines for a binary from a source that has several k lines is fine imho :)
05:41
<vagrantc>
the LTSP in etch will be good enough that we can easily backport missing features.
05:41
or so i think.
05:42
<vykarian>
sorry delay, i was afk
05:42
so...
05:42
night in bed..
05:42
i have a beowulf cluster
05:42
and have something like 10-15 LTS clients
05:42
which are celeron 2.53
05:42
running only shell
05:43
<vagrantc>
ogra: i was thinking we should move most of the ltspfs-specific code out of ltsp*init/ldm and into scripts in ltspfs ...
05:43
<ogra>
heh
05:43
what a waste of CPU
05:43
<vykarian>
yeah..
05:43
<ogra>
vagrantc, sounds sane
05:43
<vykarian>
so.. if I could put that inside the beowulf cluster would be nice ^^
05:43
is there already some effort for that?
05:43
<ogra>
is there a 2.6 variant of beowulf already ?
05:44
<vykarian>
yeap
05:44
1 min
05:45
<ogra>
i'm doing ubuntu, so i'm bound to the ubuntu kernel which only accepts patches that will (or is likely to) go in the upstream branch on kernel.org ... so i'm likely the wrong person to ask, but theoretically it should be possible to use beowulf with ltsp
05:45
<vagrantc>
ogra: did i tell you i split the init scripts into plugins ?
05:45
ogra: as a post-etch possibility ...
05:46
<ogra>
got a branch of that ?
05:46
<vagrantc>
ogra: yes.
05:46
<ogra>
i'll take a look for feisty :)
05:46
so you get it tested before etch ;)
05:46
<vagrantc>
ogra: http://llama.freegeek.org/~vagrant/bzr/ltsp/features/vagrant-ltsp-initscripts
05:46
ogra: :P
05:48
ogra: that branch includes most of the debian changes that you haven't merged yet, though.
05:48gigabytes has quit IRC
05:49
<ogra>
i merged over 100 revisions three or four weeks ago
05:49
there shouldnt be much i'm missing
05:49
<vagrantc>
ogra: there's some things...
05:50
ogra: i sent you an email about a few relatively minor patches for mainline
05:50
<ogra>
yep
05:50
they are trivial
05:50
did you merge gadis screen_scripts branch ?
05:51
the one he did in detroit ?
05:51
<vagrantc>
speaking of trivial: http://llama.freegeek.org/~vagrant/bzr/ltsp/features/vagrant-ltsp-boolean/
05:51
it's so simple.
05:51
ogra: i merged some of gadi's stuff, but not much.
05:52
<ogra>
why ? was it to bad ? :P
05:52
<vagrantc>
i hink i was just focused on other things ...
05:53
<ogra>
ok ... i will look through them as well
05:54MoL0ToV has quit IRC
05:56
<ogra>
ok, merged and pushed the -mainline changes
05:56
<vagrantc>
excellent.
05:56
<ogra>
it will take a moment for LP to sync it ...
05:56
<vagrantc>
ogra: may as well merge the boolean changes
05:56
<ogra>
i really need to move that branch to LP
05:57
yep thats the next one
05:57
<vagrantc>
he initscripts changes will result in a lot of conflicts ...
05:57
<ogra>
well
05:58
<vagrantc>
i've done some test merges ... the changes are big, but there's a lot of conflicts, some of which are difficult to merge.
05:58
<ogra>
i'm careful about the init stuff anyway ... i'd like to have it as upstart compliant as possible from the beginning
05:58
<vagrantc>
i basically just implemented the plugins system for ltsp-client
05:58
both init scripts ...
05:58
it was really easy.
05:59
i did something a little different from the ltsp-server stuff, though ... instead of installing all the vendors, i just install the plugins specific to that vendor ...
05:59
i.e. it only includes the Debian plugins
06:00
that way, we don't have to run lsb-release twice for each boot, which actually takes a couple seconds even on some moderately fast thin-client hardware.
06:00
<ogra>
younds good
06:01
but still i have to look into upstart for feisty and make the ubuntu side work with it
06:01
<vagrantc>
i was even thinking we might want to move ltsp-server in that direction, just to keep the binary packages slightly smaller.
06:01
<ogra>
it will give us instant booting at some point ;)
06:01
<vagrantc>
sometimes, things like upstart make me feel so.... linear.
06:04
<ogra>
heh
06:04
seems a lot of debian guys are helping with upstart already, so it might be in etch+1
06:05
whats etch+1 called btw ?
06:05
<vagrantc>
in many ways, though, i look forward to it. it seems petty slick, and possibly much easier to implement some things.
06:05
lenny
06:07
looks like upstart in debian/experimental is even current with ubuntu/feisty
06:11
<ogra>
yeah
06:11
die sysvinit
06:12
<vagrantc>
heh
06:12
we should just implement ltsp-build-client as upstart hooks or something.
06:12
<ogra>
haha
06:13
i think that would slow donw booting a tad
06:15
<vagrantc>
ogra: are you planning on getting locales working for feisty? it would probably reduce the ubuntu diff a lot.
06:16
<ogra>
well, i was planning to, yes, but that wont reduce the diff i fear
06:16
for me its just apt-get install language-pack-base-$LANG
06:17
<vagrantc>
well, you won't have to fork all your LC_ALL=C hacks anymore, though.
06:17
<ogra>
that sets everything correctly
06:17
right
06:17
<vagrantc>
so that will decrease the diff :P
06:17
<ogra>
but i'll require the language pack
06:17
which in turn forces me to set the keymap etc ....
06:18
and indeed forces translations for ldm ...
06:18
<vagrantc>
heh.
06:19
ogra: are you planning on splitting ldm into it's own source package for feisty?
06:20
<ogra>
i wasnt, but shouldnt be a prob to do so ...
06:21
<vagrantc>
i think it would make backporting easier.
06:21gigabytes has joined #ltsp
06:21
<ogra>
even though i dont see a reason why we should have anouther source ... we'll drown in branches
06:21
<vagrantc>
ldm is the primary reason it became difficult to backport to sarge.
06:22
<ogra>
right, but more sources make our life a lot harder
06:22
<vagrantc>
though the newer python policy should make that less of a problem...
06:22
<ogra>
i'm not sure a backport justifies the extra work
06:22
especially since you'll soon have a stable release to point users to
06:22
<vagrantc>
i'm not as set on the split as i once was...
06:23
well, the ldm split. i'm still set on the ltsp-server/ltsp-client split.
06:24
<ogra>
on a binary base thats totally fine with me ... on a source base we'll have to discuss each bit ... i really dont want to get into maintenance hell
06:24
<vagrantc>
sure.
06:25
i mean, i was kind of hoping to move this project to a totally unmaintainable state, but i realize not everyone shares that goal.
06:25
<ogra>
haha
06:27
what about the switch to pulse, can you do that in debian easily ?
06:27
<vagrantc>
it looks like all the packages are there.
06:27
in etch, even.
06:27
so it probably wouldn't make backporting to etch hard
06:28
<ogra>
cool
06:28
i hope to get that done this week or the weekend
06:29
so i can finally control the volume on my music thinc client ;)

Gadi: !!!!!!!!!
11:53
Your X_HORZSYNC = "30-80" suggestion to get 1600x1200 display worked like a champ!
11:58
<Gadi>
nice. which proves the theory that im full of it :)
11:58
whatever it is
11:59
<pscheie>
More precisely, I had to set it to X_HORZSYNC = "30-90" to get 16x12
11:59
X_HORZSYNC = "30-80" only got me to 1280x1024
11:59
but even that was an improvement
11:59
oddly, setting it to 90 always gives me 16x12 no matter what res I specify
12:00
what exactly is X_HORZSYNC specifying?
12:01rxd has quit IRC
12:02One has quit IRC
12:03primeministerp has quit IRC
12:07
<Gadi>
horizontal sync frequency of the video card (to match that of the monitor it is plugged into)
12:07
you need higher frequencies to get higher resolutions
12:07cascade has quit IRC
12:08
<Gadi>
but, old CRT monitors will break if you specify too high a frequency
12:08
so the defaults are kept low
12:08
<pscheie>
If I understand things correctly, when I switch to the client machine's local install of FC6, which gives me 16x12,
12:09
the monitor reports its scan rate as 59hz
12:09
or so it says
12:09
<Gadi>
most distros use a utility to probe the monitor to ask it what frequencies and such it supports
12:10
LTSP does not
12:10
so, it uses a Xorg default (31-59)kHz
12:10
but, for many monitors, you need a higher frequency range to get higher resolutions
12:12
<pscheie>
I seem to recall from the manual for the monitor that it will handle frequencies up to around 150
12:12
speculating wildly here, would there be an advantage if ltsp had such a probing tool?
12:12
putting aside how much work it would take to develop such a thing
12:13
<jammcq>
LTSP-5 does, in Ubuntu (I'm assuming that Ubuntu already has that)
12:13
<pscheie>
ah, good things come to those who wait ;-)
12:14
what about multiple resolutions? that is, setting X_MODE_1 and X_MODE_2 never work for me
12:14
or rather, pressing Ctl-Alt-+ never does anything for me

12:20
<jammcq>
pscheie: how about on a normal Linux box, does Ctrl-Alt-+ work there?
12:21
<pscheie>
yes--well, it has in the past; I haven't tried it on this FC6 install yet
12:22
<Gadi>
!seen ogra
12:22
<ltspbot>
Gadi: ogra was last seen in #ltsp 5 hours, 52 minutes, and 41 seconds ago: <ogra> so i can finally control the volume on my music thinc client ;)
12:24
<Gadi>
anybody here using Ubuntu's LTSP (via ldm)?
12:24
don't everybody jump at once
12:26
<pscheie>
jammcq: I recall a few years ago getting the multiple X_MODEs working under LTSP but the lower resolutions ran the desktop off the screen
12:26
<jammcq>
yes
12:26
<pscheie>
isn't there a command, something like xdandd or some such that fixes that, at least in a fat client?
12:26
<jammcq>
the lower resolutions give you a "view port" of the larger screen
12:26
but that's NOT ltsp that does that
12:26
that's just the way it works in X
12:27
<Gadi>
pscheie: ur thinking of xrandr
12:27mistik1 has joined #ltsp
12:27
<pscheie>
Gadi: righto!
12:27
does that work on a tc?
12:27
<Gadi>
sure
12:29
<pscheie>
anyone have any ideas why setting X_MODE_1 & x_MODE_2 wouldn't work?
12:29
<jammcq>
I think you need 0 too
12:29
<pscheie>
yeah, I've already got that; that's the only res I get
12:30
<jammcq>
well, you'd have to make sure that all of the resolutions are supported by the hardware. the xserver will throw away invalid modes
12:30
then, once they are all valid, then it should just work
12:30
if it doesn't, you could get to a shell on the client, and look at the Xorg logfile, and see if it retained those modes you asked for
12:30
<Gadi>
pscheie: even if you only specify X_MODE_0, you should be able to change res to any lower resolution in Gnome > Screen Resolution
12:31
(your login screen will always be at the highest resolution)
12:31
<pscheie>
the odd thing is if I set the upper end of X_HORZSYNC to 80 I get 1280x1024
12:31
<Gadi>
thats not odd
12:32
<pscheie>
if I set it to 90 I get 16x12 without changing the X_MODE_0 res
12:32
<Gadi>
evidently, to get 1600x1400, you need a horizontal sync greater than 80kHz

<pscheie>
yes, but setting to higher forces 16x12?
12:32
<jammcq>
there's an interesting document from eric raymond describing the modelines and the frequencies.
12:32
<Gadi>
you mean even with X_MODE_0 specified?
12:33
<pscheie>
yes
12:33
<jammcq>
pscheie: could we see your lts.conf file?
12:33
<Gadi>
are you specifying it in the [Default] section of lts.conf or a specified section?
12:33
<pscheie>
jammcq: do you have a link to eric's doc?
12:33
<jammcq>
I can find it
12:33
<Gadi>
if specified, check the hostname on the client
12:33
your client may not be getting the setting
12:34
because it may not know its hostname

I don't think it's a hostname issue, because all the other settings I put for that particular client are working

hi, where can I get ltsp 5 from? to install in xubuntu
15:16
<jammcq>
g333k_work: you should be able to apt-get it
15:16
is it Dapper or Edgy xubuntu?
15:17
<g333k_work>
jammcq, yep xubuntu edgy
15:17
jammcq, what pkgs do I need to install?
15:19
<moquist>
ogra (anybody): what's the recommended way to get ltspfs in edubuntu (edgy)? last time I had a question like that I just started installing packages, and ya'll said "NOnononono", so this time I'm asking first. :)
15:20
<jammcq>
g333k_work: I think it's just "apt-get install ltsp-standalone-server"
15:20
<g333k_work>
jammcq, ltsp-server-standalone :p
15:20
<jammcq>
yeah, that one :)
15:20
<moquist>
jammcq: any comment on ltspfs in ubuntu?
15:20
<jammcq>
hey O'Quist
15:20mistik1 has quit IRC
15:21
<moquist>
...if it's supposed to "just work", it isn't. :(
15:21
jammcq: hey hey hey
15:21
<jammcq>
umm, i'm not sure what package you need
15:21
<moquist>
np
15:21
<g333k_work>
jammcq, it a very cool idea to integrate ltsp to distros.... I remember installinf ltsp with ltspadmin...
15:22
jammcq, now that I installed it what? should I have to run ltspadmin again?
15:22
<moquist>
hrm. it kinda looks like the packages are already installed so that it should "just work".
15:23
g333k_work: you need to run ltsp-build-client IIRC
15:23
g333k_work: IIRC that's what creates /opt/ltsp/i386
15:23
<jammcq>
'ltspadmin' is ONLY for ltsp-4.x
15:23
<g333k_work>
moquist, ok
15:23
<jammcq>
you would NEVER use it for LTSP-5
15:24
<g333k_work>
jammcq, ok... I'm just migrating to 5, so I'm pretty new again
15:24
<jammcq>
unless we modify it for use in ltsp-5, but currently, that's not what we are planning to do
15:26mistik1 has joined #ltsp
15:27
<g333k_work>
is there a manual to install ltsp 5 in ubuntu edgy¡
15:27
?
15:28
<moquist>
g333k_work: not that I know of; the recommendation is to use the edubuntu install CD.
15:28
<g333k_work>
moquist, :o
15:28
<moquist>
g333k_work: you could easily use the edubuntu install CD and then apt-get install xubuntu-desktop.
15:28
that would be *WAY* easier than what you're doing. :)
15:28
<jammcq>
https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
15:29
<g333k_work>
moquist, well I'm going in the other direction... installing xubuntu first then geting ltsp
15:29
<moquist>
g333k_work: right. I was recommending that you change direction. :)
15:30

<g333k_work>
vagrantc, ltsp-server-standalone :p
15:36
<vagrantc>
moquist: i think it's simply installing ltspfs on the ubuntu server and ltspfsd into the ltsp chroot, and setting LOCALDEV=True in the chroot's /etc/lts.conf
15:36
g333k_work: sure, if you need the dhcp server, too.
15:36
<g333k_work>
mistik1, you're lucky that it works for you...

mistik1, my friend has a compaq notebook, and we couldnt make it work.... but using ndiswrapper

I have a problem, after a while my ltsp server's hard disk start to read and read.. and my clients seem to freeze.... why? I'm out of RAM?
16:11
<jammcq>
try running top and see what it's doing
16:14
<g333k_work>
jammcq, but when it start reading and reading its impossible to do anything
16:15mistik1_ has joined #ltsp

16:15
<g333k_work>
jammcq, I will add 512mb of RAM more
16:15
<vagrantc>
g333k_work: possibly a bad hard disk, then.
16:16
i guess it could be running out of ram and falling into perpetual swapping
16:16
<g333k_work>
vagrantc, jammcq, thats why I need popup messges... to tell my clients that the server is going to be down for a minutes
16:17
vagrantc, how to solve it?
16:17
<jammcq>
take the server down. they'll get the hint pretty quickly
16:18
<vagrantc>
if the clients are froze, it won't be any surprise if they break further
16:20
<jammcq>
is it totally impossible to run anything? or does it just take alot longer for programs to come up?
16:20
and... how many clients do you have, and how much ram now?
16:20
<vagrantc>
!serversizing
16:20
<ltspbot>
vagrantc: "serversizing" is http://wiki.ltsp.org/twiki/bin/view/Ltsp/ServerSizing
16:22
<g333k_work>
jammcq, I had 1G of RAM.... and I have about 25 clients now
16:22
jammcq, all of them just using firefox
16:22
<jammcq>
that's not enough
16:22
<g333k_work>
jammcq, now I have 1,5G
16:23
<jammcq>
that's still pretty tight
16:23
<g333k_work>
jammcq, is not enough ??
16:23
<jammcq>
do you know how to see if you are swapping?
16:23
<g333k_work>
jammcq, how can I calculate how much RAM do I need for each client that I add?
16:23
jammcq, yep with the 'free' command
16:23
<jammcq>
go read the link that vagrantc just posted

huh?
16:24
you don't have any swap configured
16:24
<g333k_work>
jammcq, but I just turned it on.... lets wait some hours
16:24
<jammcq>
i'm surprised it doesn't just crash
16:25
<vagrantc>
looks like there's plent of free ram ...
16:25
g333k_work: it doesn't looke like your swap is on, though. there is "0" in the total swap.
16:33
<g333k_work>
vagrantc, yep I realized that
16:33
I'm trying to turn it on but I cant
16:35
<vagrantc>
mkswap /dev/SWAP_DEVICE && swapon /dev/SWAP_DEVICE
16:35
or maybe ubuntu has some crazy GUI swap manager... :)
16:36
<mistik1>
heh
16:38
<g333k_work>
how much swap do I need? if I have 1.5G of ram?
16:40FaithX has quit IRC
16:41
<vagrantc>
g333k_work: you'll hear everything from 1-3 times the ram.
16:43
g333k_work: so, anywhere between 1.5-4.5 GB of swap. though i tend to thing 4.5 GB of swap ... well... if you're using anywhere near that much swap, you probably just need more ram.
16:43
but i also haven't worked with servers that host more than 10-20 users at once.
