| 03:15 | <papaf> Hi all! I'm running LTSP 5.1 on ubuntu, and I'm experiencing extreme lag on various firefox 3 operations. For example, opening drop down menues in pages takes 5-6 seconds, and even menu windows are slow, albeit less. firefox 2 shows no such problems and is super fast. Where can I look?
| |
| 03:23 | <dipeshmehta2> Hello all, I have successfully setup LTSP-5 on Ubuntu, my problem is that... I am able to PXE boot at a time on any one client only, if one client is running others get busybox/initramfs prompt...., how do I allow more concurrent connections?
| |
| 03:33 | <alkisg> papaf: known bug, reported somewhere in launchpad
| |
| 03:34 | dipeshmehta2: do you see any error about dhcp before it drops to busybox?
| |
| 03:35 | <dipeshmehta2> I think no, but wait... I just check the logs again
| |
| 03:35 | bobby_C has joined #ltsp | |
| 03:35 | <alkisg> (e.g. ipconfig sends the "Linux ipconfig" vendor identifier string, so your dhcp server may refuse to lease an ip to it)
| |
| 03:38 | <dipeshmehta2> but if I shutdown the first client... then the same machine where busybox was apearing... and moreover my dhcp server has pool of 30 ip to lease
| |
| 03:38 | <papaf> alkisg: I know about that bug, but it seems that one is different. It seems that case is about heavy loading with 10+ terminals, while I have just one.
| |
| 03:39 | <alkisg> papaf: the bug I'm talking about is related to some xlib, and it shows with even 1 client right clicking on a simple www page.
| |
| 03:40 | <papaf> alkisg: oh, I saw another bug then.
| |
| 03:40 | <alkisg> There's a workaround by using an old (or patched) version of that xlib... let me see if I can find it...
| |
| 03:41 | papaf: https://bugs.edge.launchpad.net/ubuntu/+source/libxcb/+bug/277069
| |
| 03:42 | <papaf> probably firefox 2 doesn't use that functions, right?
| |
| 03:43 | <alkisg> Could be... try with the patched library to see if it gets any better, it worked fine for me
| |
| 03:43 | <dipeshmehta2> alkisg: I checked logs, dhcp leasea
| |
| 03:43 | alkisg: I checked logs, dhcp leases were granted.....
| |
| 03:44 | <alkisg> dipeshmehta2: each client should get a lease TWICE, did it?
| |
| 03:44 | <papaf> alkisg: uhm, I doubt I could patch a jaunty install...
| |
| 03:44 | <dipeshmehta2> alkisg: yes,
| |
| 03:46 | <alkisg> dipeshmehta2: when it drops to busybox, do `cat /tmp/net*` and see if next-server points to your server
| |
| 03:46 | or, see if the clients report any error before they drop to busybox...
| |
| 03:48 | <dipeshmehta2> alkisg: at client I get ubuntu splash screen for a couple of moments, then blank screen with cursor blinking on upper left corner for 3-5 minutes, and then busybox
| |
| 03:48 | <alkisg> Remove the splash screen :)
| |
| 03:48 | <dipeshmehta2> ok
| |
| 03:48 | <alkisg> sudo vi /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
| |
| 03:49 | (or amd64, whatever you have for your clients)
| |
| 03:49 | <dipeshmehta2> ok,
| |
| 03:49 | <alkisg> remove "quiet splash" from that file
| |
| 03:51 | <dipeshmehta2> ok, done.....
| |
| 03:51 | now please wait, I check again on more than one clients....

| 03:58 | <papaf> alkisg: jaunty it's still downgradeable, it seems. It is faster now, although a bit sluggish compared to firefox2
| |
| 03:58 | dipeshmehta2 has left #ltsp | |
| 03:58 | cinch has quit IRC | |
| 03:59 | <alkisg> papaf: I hope they solve this bug soon, it's rather annoying :(
| |
| 04:09 | yoshi_ has quit IRC | |
| 04:09 | <papaf> alkisg: do you happen to know what benefits does this xcb thing get us?
| |
| 04:10 | <alkisg> Nope, didn't look into it
| |
| 04:10 | <papaf> alkisg: I tried running firefox with strace and my God, a ton of futile calls. No wonder it's so slow...
| |
| 04:11 | dipeshmehta has joined #ltsp | |
| 04:16 | <dipeshmehta> alkisg:I checked again: when first client boots, it gets dhcp lease twice, but on subsequent clients, they do not get leases twice, so they waits at IP-CONFIG: eth0 done, with address, broadwast gateway rootserver, all addresses to 192.168.1.1 which is not correct.... with rootpath and filename blank........
| |
| 04:16 | <ogra> that sounds like you run another dhcp server somewhere in your net
| |
| 04:16 | <alkisg> dipeshmehta: you probably have another dhcp server runing
| |
| 04:16 | <ogra> snap
| |
| 04:16 | :)
| |
| 04:16 | morning alkisg
| |
| 04:16 | <alkisg> Faster fingers :P
| |
| 04:16 | morning!
| |
| 04:17 | <ogra> just waking up :)
| |
| 04:17 | they are not worn out by the day yet ;)
| |
| 04:17 | <alkisg> How's it going with all the installations?
| |
| 04:17 | * alkisg is writing the ubuntu0904ltsp greek installation manual... :) | |
| 04:17 | <ogra> well, pretty much done ... today is paperwork day ... writing announcements, preparing wikipages and docs
| |
| 04:18 | http://iso.qa.ubuntu.com/qatracker/build/all/all nearly all green :)
| |
| 04:22 | <dipeshmehta> alkisg: no, I checked again.... there is no another dhcp server running....
| |
| 04:23 | <ogra> no DSL router or anything that could run one ?
| |
| 04:24 | <dipeshmehta> I checked my windows server and ADSL router.... both dhcp services are disabled
| |
| 04:26 | <alkisg> dipeshmehta: let's get sure it is indeed a dhcp problem: append this line to /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default:
| |
| 04:26 | IPAPPEND 3
| |
| 04:26 | It should boot this way. But you still have to solve the dhcp problem afterwards.
| |
| 04:27 | (IPAPPEND 3 should be an a new, seperate line in that file)
| |
| 04:28 | <dipeshmehta> ok
| |
| 04:33 | after appending IPAPPEND 3 now it boots successfully,
| |
| 04:34 | <alkisg> (it *could* be an ipconfig problem; I've noticed that it has more bugs than working code... :P - OK I'm exaggerating it's actually 50%-50%)
| |
| 04:34 | dipeshmehta: now, from a client, try running `ipconfig -n eth0` to see where it gets it's DHCP lease from
| |
| 04:34 | <ogra> didnt stgraber have a solution for that ? some dhcp client you can add to initramfs
| |
| 04:34 | <alkisg> udcpd
| |
| 04:34 | <ogra> right
| |
| 04:36 | <alkisg> (11:29:11 μμ) stgraber: droalt: just apt-get install udhcpc in the chroot, then do update-initramfs -u
| |
| 04:36 | (11:29:15 μμ) stgraber: and you'll get it
| |
| 04:37 | dipeshmehta: if it turns out to be an ipconfig bug, this should help you ^^^
| |
| 04:37 | * alkisg has to go for a while, bbl. | |
| 04:40 | <dipeshmehta> alkisg: ipconfig ------ bash: command not found
| |
| 04:41 | <alkisg> dipeshmehta: on a local terminal, not one running on the server
| |
| 04:41 | What version is that?
| |
| 04:41 | <ogra> ipconfig is a klibc command its not in your path
| |
| 04:41 | <alkisg> It's there: /opt/ltsp/i386/usr/lib/klibc/bin/ipconfig
| |
| 04:41 | bbl

| |
| 08:04 | <stgraber> ogra: will you have time for LTSP at UDS this time ?
| |
| 08:04 | <ogra> if you have more convincing arguments for the text, let me know :)
| |
| 08:04 | i hope so, my team grew a lot the last months, but i'm not 100% sure
| |
| 08:04 | i should have time for one or two sessions though
| |
| 08:05 | will you register one for the amd64/dhcpd.conf issue ?

| 08:17 | <stgraber> ogra: I've scheduled a general one about LTSP in Karmic, we may discuss it here as it's not the only item that'd benefit from having a different behavior when internet is up or not (I'd also like the langpacks to be installed when possible)
| |
| 08:18 | ogra: can you make sure these actually get scheduled ? IIRC these should have been proposed a while ago :)
| |
| 08:18 | * ogra heavily objects the langpack installation ... really, ldm should ship the translations itself | |
| 08:19 | <ogra> it will eat tons of ram to keep the whole set of gtk translations in ram just for a button transaltion in a dialog thats rarely shown
| |
| 08:20 | <stgraber> makes sense, we should check ldm-dialog then as I'm pretty sure it won't get translated if you don't have the langpack
| |
| 08:20 | <ogra> stgraber, i cant make sure they are scheduled since i'm not in any team that would be responsible for ltsp ... try asking robbiew or dendrobates one of them might have it on his plate
| |
| 08:20 | team maangers decide what gets scheduled
| |
| 08:21 | stgraber, just use custom made buttons and put the translation into ldm
| |
| 08:22 | for localapps people will have to touch the chroot anyway and in that case they should install a langpack ... for a normal fully remote thin-client setup there shouldnt be any langpacks installed or loaded
| |
| 08:22 | <stgraber> ogra: for udhcp, you may also say that it's actually in Jaunty but requires you to install udhcpc in the chroot and rebuild the initramfs to turn it on
| |
| 08:23 | <ogra> well, i dont want to refer to ltsp to much here
| |
| 08:23 | what i'm proposing is a distro default to also push to debian
| |
| 08:23 | for all netboot setups
| |
| 08:24 | <stgraber> sounds good
| |
| 08:25 | <ogra> its a good point though that you only have to install it and run update-initramfs to make it the default
| |
| 08:25 | i'll mention that in the wiki
| |
| 08:25 | <stgraber> what team lead should be contacted for this one ? are you going to do it ?
| |
| 08:25 | <ogra> (once i get to the wikipages :P ... etoomanyspecs)
| |
| 08:26 | <stgraber> for LTSP, I'll check with dandrobates, ideally I'd like to see it part of the ubuntu server community rather than being an education thing :)
| |
| 08:26 | <ogra> yes
| |
| 08:27 | <alkisg> ogra, for ipconfig you may say that it's not a proper dhcp client because it doesn't respect the protocol, i.e. it doesn't support lease renewal. You may also quote the current maintainer (hpa) that said that.
| |
| 08:28 | <ogra> you dont happen to have a reference to that quote in a mail archive or something ?
| |
| 08:28 | <alkisg> yes, I think I can find it
| |
| 08:29 | <ogra> that would be cool
| |
| 08:30 | <dscastro> how can i map serial devices? i must map serial bar code reader
| |
| 08:32 | <alkisg> Heh someone is trying to push my ipconfig patches upstream: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=511959

| 08:35 | <X-TaZ> Hi here :)
| |
| 08:36 | alkisg, I just saw you name on my client's pxe. You rock
| |
| 08:36 | <alkisg> X-TaZ: you mean grubgpxe? Heh it's a little disk I use for my schools, very handy
| |
| 08:37 | But it'll be replaced by dnsmasq acting as a proxydhcp server when the new version's out :)
| |
| 08:37 | <X-TaZ> Does someone know how to make some load balancing with multiple ltsp servers ?
| |
| 08:37 | how yeah its very handy, thank you to have coded it !
| |
| 08:37 | <Appiah> ltsp-cluster
| |
| 08:37 | <alkisg> Did you see stgraber's ltsp-cluster ?
| |
| 08:37 | <Appiah> but I never tried it
| |
| 08:37 | Haven't had time
| |
| 08:38 | <X-TaZ> I'm gonna take a look at it. I have 200 clients and 8~10 servers wich will be clustered
| |
| 08:38 | davidj has quit IRC | |
| 08:40 | <cyberorg> X-TaZ, see the ltsp docs, simple clustering is supported already
| |
| 08:41 | X-TaZ, look for get_hosts
| |
| 08:41 | <X-TaZ> Thank a lot :)
| |
| 08:42 | <cyberorg> if you want to see how it should work, you can check out live DVD from here ;) http://download.opensuse.org/repositories/Education/images/iso/

| 08:43 | some details of how it works http://en.opensuse.org/LTSP/Cluster/Setup

| 08:44 | <Appiah> kiwi-ltsp
| |
| 08:45 | does that apply to ltsp in ubuntu?
| |
| 08:45 | <cyberorg> Appiah, yes, you'll have to add get_hosts script as mentioned in ltsp docs, on suse it is included in the client image
| |
| 08:46 | <X-TaZ> I can't find get_hosts in LTSP's doc :x
| |
| 08:46 | <cyberorg> X-TaZ, looking in the link in the /topic?
| |
| 08:46 | http://wiki.ltsp.org/twiki/bin/view/Ltsp/LtspDocumentationUpstream

| 08:47 | Chapter?17.?Session dispatching

| 08:47 | Gadi has joined #ltsp | |
| 08:47 | <Appiah> :D
| |
| 08:47 | <X-TaZ> Erf, my firefox did find nothing ( CTRL +F : get_hosts ) .. Thank you
| |
| 08:47 | <Appiah> yes , no
| |
| 08:48 | <ogra> while the ubuntu version uses the distro tools to build the client as the other distros do
| |
| 08:48 | <alkisg> ogra, sorry, can't find it :( But you can quote the dhcp rfc :P "If the lease expires before the client receives a DHCPACK, the client moves to INIT state, MUST immediately stop any other network processing and requests network initialization parameters as if the client were uninitialized."
| |
| 08:48 | <Appiah> right now I'm using not so real load-balancer method
| |
| 08:49 | just a DNS round robin to send clients to different servers
| |
| 08:49 | (2 servers)
| |
| 08:50 | but if this is growing larger I'd like something like ltsp-cluster
| |
| 08:50 | <ogra> Appiah, get_hosts is several years old and included in ubuntu
| |
| 08:50 | <Appiah> is it in the ltsp-docs ?
| |
| 08:50 | <ogra> should be in the upstream docs
| |
| 08:50 | <Appiah> Then I'll take a look at that
| |
| 08:51 | intelliant has joined #ltsp | |
| 08:51 | <Appiah> but that still means I have to sync my servers myself and so on
| |
| 08:51 | (can be made easier with scripts)
| |
| 08:51 | <ogra> not sure Lns ever set up a doc on https://help.ubuntu.com/community/UbuntuLTSP/ for that
| |
| 08:51 | well, you should have three servers :) one nfs-home and two app servers
| |
| 08:52 | <Gadi> screen.d/ldm: if [ -x /usr/share/ltsp/get_hosts ]; then
| |
| 08:52 | screen.d/ldm: LDM_SERVER=$(/usr/share/ltsp/get_hosts)
| |
| 08:52 | <ogra> the app servers mount home from the nef one
| |
| 08:52 | <Appiah> I do have 3 servers
| |
| 08:52 | <ogra> *nfs
| |
| 08:52 | <Appiah> one for storage and ldap
| |
| 08:52 | <ogra> right, what else do you need ? :)
| |
| 08:52 | <Appiah> What I mean is a interface for me to just update all my servers to the same version for all the packages etc
| |
| 08:53 | <ogra> ah
| |
| 08:53 | <Appiah> if I make a change on firefox on appserv1 i need to do the same in appserv2
| |
| 08:53 | etc
| |
| 08:53 | <ogra> landscape :)
| |
| 08:53 | but costs money ...
| |
| 08:53 | <Gadi> wasnt there something like puppet?
| |
| 08:53 | <Appiah> Like now It's just simple scripts to send config files here and there
| |
| 08:53 | <ogra> yeah, but then you can as well do scripting
| |
| 08:53 | <Appiah> to the other server
| |
| 08:53 | <ogra> puppet is cool but all cmdline
| |
| 08:54 | <Appiah> yes
| |
| 08:55 | nubae1 is now known as Nubae | |
| 08:57 | <Appiah> since ltsp-cluster was supposed to have some sort of http interface to manage , I was thinking it would be easy to make some more features there with scripts to to manage stuff mentiond above
| |
| 08:58 | <X-TaZ> How would you sync the users between servers ?
| |
| 08:59 | <Appiah> dont , use ldap
| |
| 08:59 | :)
| |
| 08:59 | <X-TaZ> does your coma is voluntary ?
| |
| 08:59 | <Appiah> huh?
| |
| 09:00 | <cyberorg> Appiah, this is the idea that is possible in near future http://en.opensuse.org/LTSP/Fatclient/Cluster
| |
| 09:00 | <X-TaZ> "dont , use ldap" or " dont use ldap" ther's a diffrence :s ( i don't understand very well english )
| |
| 09:00 | <Appiah> cyberorg: sweet
| |
| 09:00 | I mean "Dont sync the users"
| |
| 09:00 | "Use ldap instead"
| |
| 09:00 | :D
| |
| 09:00 | <X-TaZ> Ok thank you
| |
| 09:01 | <Appiah> sorry for the confusion
| |
| 09:01 | cyberorg: how far away is the near-feature in this case? end of the year?
| |
| 09:02 | <cyberorg> to set up a fatclient(diskless node) is simple http://en.opensuse.org/LTSP/Fatclient so creating a cluster using those should be easy enough
| |
| 09:02 | possibly as near as someone writing a wiki howto :)
| |
| 09:02 | <Appiah> do you know the big diff between this and ltsp-cluster ?
| |
| 09:03 | <ogra> heavy client specs
| |
| 09:03 | <cyberorg> ltsp-cluster is much more scalable
| |
| 09:03 | <ogra> a fatclient cluster essentially needs a full pc as client
| |
| 09:03 | <cyberorg> ogra, correct, but just diskless
| |
| 09:04 | <ogra> an ltsp-cluster is jutst a clusetr of ltsp servers still operating in ltsp ode

| 09:06 | <ogra> well, ees are at least appearing on the screen if i press the key
| |
| 09:06 | mms seem to start doing that only on a case by case base
| |
| 09:07 | <cyberorg> it's getting selective now :)
| |
| 09:07 | <ogra> the kbd isnt even 10 years old ... damned
| |
| 09:15 | <cyberorg> i've got just 1 keyboard over 10 y old, quite a few keys don't work, the original "Cherry" keys
| |
| 09:16 | * ogra uses a SUN kbd atm ... one of the first USB ones they had | |
| 09:17 | <cyberorg> oracle :)
| |
| 09:18 | <X-TaZ> I was reading the web page of ltsp-cluster and I saw " ltsp-cluster-pxeconfig - Gets the configuration from the control center and generate symlinks for each node "
| |
| 09:18 | What does it mean ? Do I need thick package if my clients are using pxe to lan boot ?

| 14:05 | <zamba> how does ltsp work with virtualization? like vmware, vbox or xen?
| |
| 14:05 | <alkisg> vbox here, works fine
| |
| 14:07 | <zamba> what distro is your host os?
| |
| 14:07 | <vagrantc> zamba: i use xen for LTSP servers, and virtualbox for testing servers and thin clients.
| |
| 14:07 | zamba: on debian
| |
| 14:07 | <zamba> vagrantc: that works fine too? no hickups?
| |
| 14:07 | <vagrantc> zamba: works great
| |
| 14:07 | <zamba> someone wrote something here yesterday about nbd (or something?) not working if you virtualize it?
| |
| 14:07 | that you had to use nfs instead..?
| |
| 14:07 | <alkisg> zamba, vbox for guest and host
| |
| 14:08 | <vagrantc> zamba: don't know any reason you would have to use NFS rather than NBD, but Debian defaults to NFS, so that's what i've mostly tested.
| |
| 14:09 | <zamba> vagrantc: are you using other guest os-es too?
| |
| 14:10 | <alkisg> zamba, no, that's a "normal" error messages that's displayed but does not affect anything.
| |
| 14:10 | <zamba> alkisg: ok
| |
| 14:10 | <alkisg> I guess the person that wrote it had other problems, just saw that error message and thought that was the problem.
| |
| 14:10 | <zamba> and how does network work in xen? i want to be able to trunk different vlans up to my physical server.. is it possible to then get "native" network connectivity to the different guests instead of doing some NAT tricks and so on?
| |
| 14:11 | <alkisg> (sorry, ubuntu for guest and host - my kid doesn't let me to use the keyboard :P)
| |
| 14:11 | <vagrantc> zamba: i just use debian, though i have xen server running ubuntu as an application server.
| |
| 14:11 | <zamba> alkisg: i gathered that much :)
| |
| 14:13 | <vagrantc> zamba: no need for NAT, really.
| |
| 14:13 | zamba: but sometimes it's easiest, depending on what you're trying to do.
| |
| 14:13 | <zamba> vagrantc: so you can trunk up to the host os and then run multiple vlans to the guest os?
| |
| 14:13 | <vagrantc> zamba: i don't really understand what sort of trunking you're talking about. trunk has many meanings.
| |
| 14:14 | <zamba> 802.1q
| |
| 14:14 | <vagrantc> the typical configuration i use is two network cards in the server, one for the thin client network, and one to get internet access
| |
| 14:14 | <zamba> that's NAT-ing
| |
| 14:14 | <vagrantc> zamba: like bridge-utils
| |
| 14:15 | zamba: no NAT involved- the thin clients do not have access to the internet
| |
| 14:15 | <zamba> i guess my question is a bit OT, since it really is about xen and not ltsp
| |
| 14:15 | yeah
| |
| 14:15 | so this is related to xen
| |
| 14:15 | the guest os running ltsp for you.. that gets its network connectivitiy how?
| |
| 14:16 | <vagrantc> zamba: i really don't understand what you're asking.
| |
| 14:16 | <zamba> ok :)
| |
| 14:16 | on the physical server.. let's say you have only one NIC..
| |
| 14:17 | <vagrantc> what a shame.
| |
| 14:17 | <zamba> so only one physical way to reach the outside world
| |
| 14:17 | for the sake of discussion :)
| |
| 14:17 | <vagrantc> in that case, set up the virtual server to get inernet access, and set up some virtual networks for the thin clients.
| |
| 14:18 | get internet access through the single physical NIC
| |
| 14:18 | trivial with virtualbox.
| |
| 14:18 | <zamba> hm.. i should probably ask this question in #xen :)
| |
| 14:18 | it's not related to ltsp at all, so
| |
| 14:18 | <vagrantc> haven't used xen as a thin client, so i don't know how that works
| |
| 14:18 | * vagrantc is happy to pass the buck to #xen | |
| 14:18 | <zamba> forget those thin clients for a moment :)
| |
| 14:18 | this is purely a virtualization question
| |
| 14:19 | but yeah, i'll ask on #xen
| |
| 14:19 | thanks for your answers for the ltsp bit

| 16:42 | <Gadi> has anyone here experienced race conditions with audio? ie on some hardware with some drivers you sometimes get sound, and other times not?
| |
| 16:42 | I ask because I am tempted to put in code to alleviate such race conditions
| |
| 16:42 | code such as:
| |
| 16:42 | unset soundcard_ready
| |
| 16:42 | while [ -z "$soundcard_ready" ]; do
| |
| 16:42 | amixer -c0 >/dev/null 2>&1
| |
| 16:42 | [ "$?" = 0 ] && soundcard_ready=1
| |
| 16:42 | sleep 2
| |
| 16:42 | done
| |
| 16:43 | of course, forked into a background process
| |
| 16:43 | so configuring audio volumes and running pulseaudio would happen only once the sound card is ready

| |
| 20:22 | !question
| |
| 20:22 | <ltspbot`> Ryan52: "question" is if you have a question about ltsp, please go ahead and ask it, and people will respond if they can. please also mention the linux distro and release you're using. :)
| |
| 20:22 | <Ryan52> aminus: ^^
| |
| 20:24 | <aminus> which ltsp would be good for an optiplex gx1????
| |
| 20:24 | <Ryan52> what do you mean which ltsp?
| |
| 20:26 | <aminus> theres 2 different versions 4.2 and 5. i believe...
| |
| 20:27 | <Ryan52> !docs
| |
| 20:27 | <ltspbot`> Ryan52: "docs" is For the most current documentation, see http://wiki.ltsp.org/twiki/bin/view/Ltsp/LtspDocumentationUpstream
| |
| 20:27 | <aminus> thanks
| |
| 20:27 | makghosh has quit IRC | |
| 20:27 | <Ryan52> "The bare minimum for a thin client to work is about 48MB, but it will be unusably slow, so it is recommended to install at least 128MB Ram, with 256MB Ram if you can spare it."
| |
| 20:28 | "For using the default, secure mode of LTSP, you'll need to have a slightly faster CPU. Any 533 MHz or better CPU should provide acceptable performance. "
| |
| 20:28 | aminus: if it meets that, ltsp 5 should be fine.
| |
| 20:28 | aminus: otherwise, I dunno. maybe ltsp 4.2 needs less. but it's not maintained anymore...
