| 08:35 | <pablo-uy-mvd> hi! dhcp is up and working, in daemons.log i see that a client nic asked for a ip, my dhcp servers does the offer.. and its a loop in these 2 actions. in the client side the client says "no ip addres"
| |
| 08:35 | <cliebow_> better pastebot.ltsp.org your dhcpd.conf
| |
| 08:36 | <pablo-uy-mvd> my dhcpd.conf is in http://pastebot.ltsp.org/119
| |
| 08:36 | RiXtEr has joined #ltsp | |
| 08:37 | <Lumiere> cliebow_: any reason we're not using lisppaste?
| |
| 08:37 | Guaraldo has quit IRC | |
| 08:37 | mhterres has quit IRC | |
| 08:37 | <cliebow_> Lumiere, i never heard of it...
| |
| 08:38 | sep is now known as sepski | |
| 08:38 | <cliebow_> pablo-uy-mvd, i see nothing at all wrong with dhcpd.conf
| |
| 08:38 | !lisppaste
| |
| 08:38 | <ltspbot> cliebow_: Error: "lisppaste" is not a valid command.
| |
| 08:38 | Guaraldo has joined #ltsp | |
| 08:39 | <pablo-uy-mvd> cliebow: yes its strange... daemons.log says dhcp is offering ips to the nics of my clients.. but something goes wrong inmediatly after that offer cause clients say no ip address
| |
| 08:39 | <cliebow_> ohhh. it cant hurt to define next-server in there..where your tftp stuff is
| |
| 08:39 | <jkommeri> pablo-uy-mvd: have you tried dhclient?
| |
| 08:39 | Guaraldo has left #ltsp | |
| 08:40 | <RiXtEr> hey all, say i wanted to use this variable set remote_dir "\/mnt\/md0\/\`date \"\+\%A\"\`" , only make it a constant variable. The script is ran around midnight, so it changes in the middle of the script, I would like it to always be just one day.
| |
| 08:41 | Guaraldo has joined #ltsp | |
| 08:41 | <Lumiere> cliebow_: paste.lisp.org
| |
| 08:41 | <pablo-uy-mvd> jkommeri: its a diferent dhcpserver?
| |
| 08:42 | <jkommeri> you have multiple?
| |
| 08:42 | mhterres has joined #ltsp | |
| 08:42 | <cliebow_> Lumiere:i nevr seen that before..ill try it
| |
| 08:42 | <Lumiere> cliebow_: you can get a bot from them
| |
| 08:42 | that does paste
| |
| 08:42 | <jkommeri> pablo-uy-mvd: I meant that you can check whether your dhcp-server is working with dhclient
| |
| 08:43 | * Lumiere uses lisppaste5 in #schooltool | |
| 08:43 | <pablo-uy-mvd> jkommeri: ok. how do i check that?
| |
| 08:43 | <jkommeri> pablo-uy-mvd: just use the command with no parameters
| |
| 08:43 | it should broadcast a query
| |
| 08:44 | <cliebow_> Lumiere, sure sounds like a great idea..jammcq must be operator here?
| |
| 08:45 | ChanServ sets mode: +o Lumiere | |
| 08:45 | <Lumiere> that I can help you with XD
| |
| 08:46 | but yes
| |
| 08:46 | jammcq is the owner of the channel
| |
| 08:46 | <cliebow_> lets try it..dont you think?
| |
| 08:48 | <jkommeri> ogra: are you there?
| |
| 08:49 | <Lumiere> I'll look in a moment

| |

| |
| 09:30 | MrNobody has joined #ltsp | |
| 09:30 | <MrNobody> hi
| |
| 09:32 | does anyone know why do I get RPC: portmap not responding (errno -5) when I try to mount a NFS share in a client terminal?. portmap,nfs are running and listening and exports are configured correctly..
| |
| 09:37 | <cliebow_> hmm..does netstat -anp|grep ":111" tell you anything?
| |
| 09:43 | adding memory..bbiab
| |
| 09:43 | cliebow_ has quit IRC | |
| 09:44 | <MrNobody> cliebow:sorry went to pee. yep netstat -an gives me the following tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN
| |
| 09:44 | udp 0 0 0.0.0.0:111 0.0.0.0:*
| |
| 09:45 | <jammcq> MrNobody: do this on the server: showmount -e
| |
| 09:45 | <MrNobody> I had: permission denied errors before but after a disable the firewall using redhat-config-securitylevel I just get not responding...
| |

| 09:48 | <MrNobody> jammcp: it shows /var/opt/ltsp/swapfiles 192.168.0.0/255.255.255.0(rw,no_root_squash,async)
| |
| 09:48 | /opt/ltsp/i386 192.168.0.0/255.255.255.0(ro,no_root_squash,sync)
| |
| 09:48 | <jammcq> ok, so that looks fine. next thing to check is the 'broadcast' setting in dhcpd.conf
| |
| 09:50 | <MrNobody> option broadcast-address 192.168.0.255;
| |
| 09:50 | <jammcq> hmm, that should be fine
| |
| 09:51 | <MrNobody> if I do tail -f /var/log/messages while the client tries to mount the filesystem. it says : rpc.mountd autenticad mount request from 192.168.0.10
| |
| 09:51 | <jammcq> hmm
| |
| 09:52 | cliebow_ has joined #ltsp | |
| 09:53 | marek82 has joined #ltsp | |
| 09:56 | <jkommeri> MrNobody: what have you set as nfsroot in dhcpd.conf
| |
| 09:56 | cliebow_ has quit IRC | |
| 09:57 | <MrNobody> if you mean: option root-path "192.168.0.254:/opt/ltsp/i386";
| |
| 09:57 | where 192.168.0.254 is the IP of my server
| |
| 09:57 | <jkommeri> ok
| |
| 09:57 | cliebow_ has joined #ltsp | |
| 09:57 | <jkommeri> I have that without ip
| |
| 09:57 | option root-path "/opt/ltsp/i386";
| |
| 09:57 | Blinny has joined #ltsp | |
| 09:58 | <jkommeri> I had the same problem
| |
| 09:58 | <MrNobody> did that solve it?
| |
| 09:58 | <jkommeri> try without that ip for instance
| |
| 10:00 | <jammcq> for ltsp-4.2, that should work just fine
| |
| 10:00 | <MrNobody> ok thanks. bt I am using ver 3.0 (a school assignment)
| |
| 10:00 | <jkommeri> ok
| |
| 10:00 | <jammcq> oooooooh
| |
| 10:01 | another one of those school assignment guys
| |
| 10:01 | even 3.0 should work fine with that
| |
| 10:01 | <jkommeri> :)
| |
| 10:01 | <Blinny> jammcq: I don't know if you saw - that K12 firefox crashing problem turned out to be a bug in FF's javascript handling that caused a display manager crash.
| |
| 10:01 | <MrNobody> thanks :) I will give it a shot
| |
| 10:02 | <jammcq> Blinny: wow, that's really strange. did you find a fix for it?
| |
| 10:03 | <ogra> MrNobody, so sbalneav's mail to your teacher had no effect ?
| |
| 10:03 | <jsgotangco> hey you guys how's UES
| |
| 10:03 | <Blinny> jammcq: Turning off javascript in FF seems to work (; -- But no, unfortunately not. I think it's more of an i810 bug than anything because OO Impress's javascript stuff caused the same behavior.
| |
| 10:04 | <jammcq> that's freaky
| |
| 10:04 | I do an awful lot of javascript coding, and I can't imagine how that would affect the display mgr
| |
| 10:05 | <cliebow_> sucking up a pile of memory?
| |
| 10:05 | <Blinny> Yeah. It was one of those thing that I stumbled upon accidentally, and kept thinking "this can't be right".
| |
| 10:06 | <ogra> Blinny, what do yu have in /etc/firefox/firefoxrc ?
| |
| 10:06 | <Blinny> ogra: I don't have an /etc/firefox
| |
| 10:06 | <ogra> using any esd related entry there will likely make newer ff's crash
| |
| 10:07 | <Blinny> This is 1.5.0.4
| |
| 10:07 | <Lumiere> ogra: enjoying UES?
| |
| 10:07 | <ogra> Lumiere, indeed :)
| |
| 10:07 | <Lumiere> I hear schooltool is a popular discussion in the edubuntu BOF XD
| |
| 10:08 | * Lumiere works for the cando project now | |
| 10:08 | <highvoltage> Lumiere: there's a schooltool maintainer here, so discussion around it did come up quite a bit
| |
| 10:08 | <Lumiere> highvoltage: I know...
| |
| 10:08 | highvoltage: I work for the project... as in I get paid for it
| |
| 10:08 | Lumiere sets mode: -o Lumiere | |
| 10:09 | <highvoltage> Lumiere: are you implying that there are people working on it that are not being paid for it? :p
| |
| 10:09 | <jsgotangco> highvoltage: hey you
| |
| 10:09 | <highvoltage> hey jsgotangco
| |
| 10:09 | <Lumiere> at the moment... there are a couple
| |
| 10:10 | <highvoltage> ok, I didn't realise.
| |
| 10:10 | <jsgotangco> highvoltage: so how is sevilla treating you
| |
| 10:10 | gavinmc has joined #ltsp | |
| 10:10 | <Lumiere> highvoltage: it's mostly student cando developers who will be paid stipend over the summer ^^
| |
| 10:11 | <ogra> Blinny, hmm, probably fedora sets th eFIREFOX_DSP variable somewhere else

| 10:11 | <jsgotangco> wow interesting hosts
| |
| 10:11 | <ogra_> Blinny, hmm, probably fedora sets the FIREFOX_DSP variable somewhere else
| |
| 10:11 | <highvoltage> jsgotangco: weather is getting a bit better, the education summit has been good, busy winding down now
| |
| 10:11 | <Blinny> ogra_: Dig. But fixing it in FF won't cure the OOo ails though.
| |
| 10:11 | <ogra_> i only know that FF starts crashing in debian and ubuntu if it is set to something thats not "none"
| |
| 10:11 | MrNobody has quit IRC | |
| 10:11 | <jsgotangco> that's good to know

| |
| 10:17 | yanu has joined #ltsp | |
| 10:18 | <ogra_> jkommeri, note really ... its not yet implemented, even though pulse is able to
| |
| 10:18 | *not
| |
| 10:19 | you can look at the options set in /opt/ltsp/i386/etc/init.d/ltsp-client script
| |
| 10:22 | cliebow_ has quit IRC | |
| 10:22 | cliebow_ has joined #ltsp | |
| 10:24 | <jkommeri> ogra: ok, so pulseaudio should be able to use microphones

| 13:15 | <str4nd> Argh, need Debian help, how to put eth0 to automatic bring up at boot?
| |
| 13:15 | Now, if I reboot my server, I must to write ifup eth0
| |
| 13:24 | <Blinny> str4nd: I'm a Fedora user.. but surely Google knows the answer? Or ubuntu.com ?
| |
| 13:24 | Or #ubuntu?
| |
| 13:25 | str4nd: If I had to guess, I'd say there was a checkbox somewhere in 'System Settings->Networking'
| |
| 13:28 | <sutula> str4nd: On Debian, briefly, /etc/init.d/networking brings it up
| |
| 13:29 | str4nd: /etc/network/interfaces is the main file you'd probably want to modify to add/change interfaces
| |

| 15:03 | <MRH2> hi anybody know of any plans to integrate an NX client into LTSP
| |
| 15:03 | <vagrantc> MRH2: what sort of integration are you wanting? i believe you can configure LTSP clients to use it ...

| 15:04 | but as far as i know, there are no free software NX client implementations ...
| |
| 15:05 | <MRH2> ok anyone know of any pointers to adding the nx client to ltsp as an addon?
| |
| 15:07 | trying to get an ltsp terminal connecting to a freenx server
| |
| 15:07 | :)
| |
| 15:07 | <vagrantc> MRH2: what distro?
| |
| 15:08 | <MRH2> i am using 4.2 on centos5
| |
| 15:14 | <Guaraldo> MRH2: I have NX Client instaled on my LTSP server (4.2), and I can logon any X server with XDMCP and SSH enabled...
| |
| 15:15 | Ah!, shure, and NX server installed
| |
| 15:15 | ops... %s/shure/sure
| |
| 15:15 | <MRH2> maybe if i used ltsp 5 it would be easier
| |
| 15:16 | <Guaraldo> MRH2: You want to use NX Client on thinclients to access server?
| |
| 15:16 | <MRH2> yep

| 15:19 | <Guaraldo> MRH2: I never tryed this... It must be very easier on LTSP5 (dpkg -i nxpackages)... bun on LTSP4.2 I don't think it's possible... :-/ Maybe if you could get the tarballs to compile, changing the destination directory and enabling localapps on clients...
| |
| 15:19 | <mhterres> MRH2: why ?
| |
| 15:19 | <Guaraldo> mhterres: encripted access, maybe!
| |
| 15:19 | <vagrantc> http://wiki.ltsp.org/twiki/bin/view/Ltsp/FreeNX
| |
| 15:19 | <mhterres> MRH2: NX is not a good protocol, it will consume much bandwidth
| |
| 15:20 | <MRH2> if i'm reading this right in a nutshell ltsp 5 uses big chunks of the distro (incl kernel?) to take advantage of the distro maintaining this stuff anyway.
| |
| 15:20 | <mhterres> yep
| |
| 15:20 | privet has quit IRC | |
| 15:20 | <mhterres> this is the ltsp 5 approach
| |
| 15:20 | different from 4.2
| |
| 15:20 | privet has joined #ltsp | |
| 15:20 | <MRH2> so doesn't that make it heavy (slow)
| |
| 15:21 | <vagrantc> it has incurred a little performance hit, to varying degrees.
| |
| 15:24 | http://wiki.ltsp.org/twiki/bin/view/Ltsp/WorkInProgress#NX
| |
| 15:24 | <MRH2> cool
| |
| 15:25 | i'll give it a shot
| |
| 15:25 | <GiantPickle> I've got one session that died on me saying on a particular terminal. There was a fatal error with gdm. Rebooting that terminal or killing X on that terminal will not allow that user to now login, but I can log other users on to that terminal. Can someone tell me what is wrong?
| |
| 15:25 | erm... died on a particular terminal, saying there was...
| |
| 15:25 | <MRH2> user processes still running on the server?
| |
| 15:26 | <GiantPickle> doesn't look to be

| |
| 16:25 | <vagrantc> frk2: ask a question and people will try to answer
| |
| 16:25 | well, i guess the answer is "yes, people are using ltsp 5 with Feisty"
| |
| 16:25 | :)
| |
| 16:26 | <frk2> heh
| |
| 16:26 | excellent
| |
| 16:26 | :)
| |
| 16:26 | well - my issue is with ssh X forwarding
| |
| 16:26 | <vagrantc> how many, i can't say...
| |
| 16:26 | <frk2> seems to introduce quite a bit of lag (in graphical performance)
| |
| 16:27 | the desktop is FAR more responsive with XDMCP
| |
| 16:27 | <vagrantc> sure
| |
| 16:27 | <frk2> was just wondering if theres anything i can do to speed up ssh - as i think its a excellent idea
| |
| 16:28 | <vagrantc> the main thing would be to turn off encryption, but that requires recompiling ssh
| |
| 16:28 | <frk2> couldnt find anything in the lists or online- so i was wondering if I'm the only one complaining :)
| |
| 16:28 | hmm.. that was my last resort
| |
| 16:29 | <vagrantc> it's definitely an issue ... there's not much more to be done that we've come up with yet.
| |
| 16:29 | <frk2> hmm
| |
| 16:29 | i guess i'll try that
| |
| 16:30 | but i'm guessing this makes its almost unusable in production
| |
| 16:30 | <vagrantc> or just using XDMCP ... but then you loose local devices and such ...
| |
| 16:30 | <frk2> since im running like a 8-10 person network off a VERY powerful server
| |
| 16:30 | Xeon 2.4G 2Gb ram - AND its slowing down-- BADLY.
| |
| 16:30 | <cliebow> vagrantc:is thaat right..lose local devices if udsing xdmcp
| |
| 16:30 | ?
| |
| 16:30 | <frk2> yes
| |
| 16:31 | i think ldm runs a script (through ssh) - a feature you lose out in XDMCP
| |
| 16:31 | to mount the ltspfs devices
| |
| 16:31 | man- the local device support through ltspfs is SO awesome
| |
| 16:31 | <cliebow> hmm.ltspfs is independent of ssh
| |
| 16:32 | <vagrantc> scotty's working on getting both XDMCP and LDM to work with local devices ... don't know how far along it is
| |
| 16:32 | cliebow: not in the debian and ubuntu ltsp 5 implementations
| |
| 16:32 | <frk2> no i know.. i think LDM makes the local devices happen (as far as i can see)
| |
| 16:32 | by ssh'ing and running a script- i might be wrong there
| |
| 16:32 | <vagrantc> yes, there are scripts executed through the ssh tunnel
| |
| 16:33 | <frk2> have you tried without encryption, vagrantc?
| |
| 16:33 | does it help?
| |
| 16:33 | <cliebow> i have to read them..but ihavnt evgen gotten alal the way thru the initramfs yet
| |
| 16:33 | <frk2> well ofcourse it will - but how much- will it be close to xdmcp performance?
| |
| 16:33 | <vagrantc> i haven't tried it, but i hear it works like a plain-text read-my-keystrokes charm :)
| |
| 16:33 | <frk2> hahahah
| |
| 16:33 | well
| |
| 16:34 | the only option is startx
| |
| 16:34 | <vagrantc> performance wise, it makes a big difference.
| |
| 16:34 | <frk2> where the FIRST thing you do is give ure password away :P
| |
| 16:34 | atleast the intiial password handshake is challenge/response in ssh.. even if the session is unencrypted
| |
| 16:35 | <vagrantc> cliebow: what are you reading?
| |
| 16:35 | <frk2> cool
| |
| 16:35 | im doing that RIGHT now
| |
| 16:35 | even though its 2.30am in my part of town
| |
| 16:35 | <cliebow> trying to understand the workings of the initramfs
| |
| 16:35 | <vagrantc> cliebow: ah.
| |
| 16:35 | <frk2> I just wish i could turn off encryption by saying 'encryption = off' in sshd_config
| |
| 16:35 | :)
| |
| 16:36 | <vagrantc> supposedly, it was approved for the ssh in ubuntu to get something like that some time ago, but it hasn't happened yet.
| |
| 16:36 | upstream absolutely refuses to allow it
| |
| 16:36 | <frk2> yeah its obviously gay
| |
| 16:36 | defeats the purposes of 'secure' shell
| |
| 16:37 | <vagrantc> ssh implements a lot of nice features beyond encryption ...
| |
| 16:37 | <cliebow> vagrantc: did you see sbalneavs rescue ..
| |
| 16:37 | saved a life
| |
| 16:37 | <frk2> i know.. but encryption was the main purpose
| |
| 16:37 | <vagrantc> but i can see how having the possibility of running an insecure cipher might make a security compromise easier even if it were disabled.
| |
| 16:38 | * vagrantc doesn't use flash | |
| 16:38 | * vagrantc didn't see it in person either | |
| 16:39 | <frk2> thanks vagrantc
| |
| 16:39 | i guess openssh unencrypted is what im gonna do
| |
| 16:39 | funny nobody online has complained about this
| |
| 16:39 | <vagrantc> oh, they have
| |
| 16:39 | <frk2> i cant find ANYTHING
| |
| 16:39 | i mean
| |
| 16:39 | like 1-2 posts
| |
| 16:40 | but they just decide that xdmcp is the way to go
| |
| 16:40 | <vagrantc> well, there's some simplicity to that ... :)
| |
| 16:40 | japerry has quit IRC | |
| 16:41 | <vagrantc> if we get localdev and other support working with both XDMCP and LDM then it probably makes less sense to have an unencrypted ssh session
| |
| 16:41 | <frk2> no man
| |
| 16:41 | load balancing is almost an impossibility with xdmcp
| |
| 16:41 | SO easy with ssh
| |
| 16:41 | <vagrantc> trivial.
| |
| 16:41 | <frk2> what with xdmcp?
| |
| 16:42 | <vagrantc> yeah
| |
| 16:42 | <frk2> like using what for instance?
| |
| 16:42 | <vagrantc> you write a chooser that does the selection for you
| |
| 16:42 | <frk2> are you talking about things which guess out XDM_SERVER for you?
| |
| 16:42 | yeah
| |
| 16:42 | you could
| |
| 16:43 | <vagrantc> or set up round-robin DNS on the hostname for the XDMCP server
| |
| 16:43 | <frk2> okay THAT does not work
| |
| 16:43 | have you tried it?
| |
| 16:43 | lts.conf doesnt like hostnames there
| |
| 16:43 | <cliebow> works for trask..
| |
| 16:43 | <frk2> ok i tried it like 2 weeks ago.. not on ubuntu though
| |
| 16:44 | on Suse 9
| |
| 16:44 | but thats not load balancing
| |
| 16:44 | <cliebow> load lghtening?
| |
| 16:44 | <frk2> with ssh i can just do lvs
| |
| 16:44 | the XDM_SERVER deal is nice though
| |
| 16:45 | <vagrantc> it's a form of load balancing.
| |
| 16:45 | <frk2> i saw something which has agents on all X servers which can poll how many users and stuff and on there
| |
| 16:45 | i guess that would work
| |
| 16:45 | <cliebow> how many users are you planning?
| |
| 16:46 | <frk2> my largest client has 150
| |
| 16:46 | doing really gay things to distribute on 3 servers
| |
| 16:46 | basically dns round robing on the NFS server used for the root path
| |
| 16:46 | its really bad
| |
| 16:46 | but the hostname in lts.conf was not working with Suse 9
| |
| 16:47 | Ltsp 4.1
| |
| 16:47 | <cliebow> yeah i can see where it could ..150 terminals.huh..at use at once
| |
| 16:47 | <vagrantc> the more clients you have, the more likely round-robin DNS will be effective :)
| |
| 16:47 | <cliebow> frk2:just use mac addy
| |
| 16:47 | <frk2> i know.. on XDM_SERVER yes, on nfs root path its awful regardless
| |
| 16:47 | MAC addy?
| |
| 16:47 | <cliebow> sure
| |
| 16:47 | <frk2> oh to force xservers for certain thin clients?
| |
| 16:47 | <cliebow> and 4.2 rockS for speed
| |
| 16:47 | Guaraldo has left #ltsp | |
| 16:48 | muh2000 has quit IRC | |
| 16:49 | <frk2> vagrantc - is there a config option i can pass to ssh server or do i have to edit source to disable encryption?
| |
| 16:49 | <cliebow> 4.2 is a quantum leap from 4.1
| |
| 16:49 | <frk2> yeah i got another client running 4.2 with ubuntu- rocks!
| |
| 16:50 | but local device support through SMB is pretty bad
| |
| 16:51 | hmm
| |
| 16:51 | looks like no config option
| |
| 16:51 | :(
| |
| 16:54 | <cliebow> no..4.2 has ltspfs
| |
| 16:56 | all my terminals are orphaned for ltsp5..most for 4.2

| |
| 17:07 | command = ['ssh'] + ssh_opts + ssh_auth + ssh_remote_command
| |
| 17:08 | well, a little afte rthat ...
| |
| 17:08 | <frk2> in ldm right?
| |
| 17:08 | i found it
| |
| 17:09 | <vagrantc_> yes, "where in ldm" suggested to look in ldm :)
| |
| 17:09 | <frk2> :)
| |
| 17:09 | <vagrantc_> but i guess it could've been in another part
| |
| 17:09 | <frk2> okay
| |
| 17:09 | so
| |
| 17:09 | theres no way to disable the cipher
| |
| 17:09 | i can put in some shit like arcfour
| |
| 17:10 | <vagrantc_> is that faster than blowfish ?
| |
| 17:10 | <frk2> its the LAST one in the list
| |
| 17:10 | 'in order of preference'
| |
| 17:10 | so i guess it must be
| |
| 17:11 | its the worst cipher known to man, apparently
| |
| 17:11 | <dberkholz> preference is probably strength, not speed
| |
| 17:11 | * vagrantc_ see aes256-ctr as the last | |
| 17:11 | <dberkholz> not necessarily correlated
| |
| 17:11 | <frk2> true
| |
| 17:11 | i was following this guy

| |
| 17:12 | <dberkholz> http://www.psc.edu/networking/projects/hpn-ssh/theory.php also claims arcfour is fastest, though

| 17:15 | <frk2> hmmm
| |
| 17:15 | okay
| |
| 17:15 | if encryption is not causing the lag
| |
| 17:15 | then what is
| |
| 17:15 | <vagrantc_> why do you say it's not encryption?
| |
| 17:16 | <frk2> actually i just found a bunch of unrelated posts - people saying that X interactive traffic would be not TOO affected
| |
| 17:16 | NX does ssh too
| |
| 17:16 | its almost like the connection is 'bufferred'
| |
| 17:16 | <vagrantc_> NX does some things locally ... which is clever.
| |
| 17:16 | <frk2> yeah like caching
| |
| 17:16 | why didnt ltsp 5 just use NX?
| |
| 17:17 | :)
| |
| 17:17 | <vagrantc_> there is no free software NX client, for one.
| |
| 17:18 | <dberkholz> well, there is knx
| |
| 17:18 | <frk2> yeah i thought there was
| |
| 17:18 | no but isnt there FreeNX?
| |
| 17:18 | <vagrantc_> freenx is server only, last i heard
