| 09:44 | <dobber> on ltsp client, how can I setup vpn after the network is started
| |
| 09:50 | Trixboxer has joined IRC (Trixboxer!~Trixboxer@115.124.115.71) | |
| 09:52 | <vmlintu_> dobber: what kind of vpn?
| |

| 09:54 | mealstrom has left IRC (mealstrom!~mealstrom@46.63.55.254, *.net *.split) | |
| 09:56 | <dobber> pptp
| |
| 09:57 | <vmlintu_> Where does it connect to? Some outside server?
| |
| 09:59 | <dobber> yes
| |
| 09:59 | <vmlintu_> if you are using ltsp thin clients, you need to run it on the ltsp server
| |
| 10:00 | ogra_ has joined IRC (ogra_!~ogra@p5098ed03.dip0.t-ipconnect.de) | |
| 10:01 | <dobber> I have fat clients. I guess I need to change the initrd and add the vpn connection to it
| |
| 10:02 | mealstrom has joined IRC (mealstrom!~mealstrom@46.63.55.254) | |
| 10:02 | <dobber> the vpn server is on another machine in the local network of the ltsp server
| |
| 10:04 | <vmlintu_> ok.. how the vpn client authenticates itself to the server?
| |
| 10:05 | do enter username/password or something else?
| |
| 10:07 | if it's enough that the vpn works when user logs in, you could start it in session setup scripts or from PAM
| |
| 10:08 | <dobber> with pptpsetup --lots --of --options
| |
| 10:09 | yes i have user/pass
| |
| 10:09 | ok then, let me try it
| |
| 10:10 | <vmlintu_> are the usernames and passwords same for the vpn server as for the fat clients?
| |
| 10:10 | If that's the case, you could catch the username/password in PAM stack and pass it on to the vpn client so that it connects automatically
| |
| 10:10 | <dobber> not yet, but i want to make them the same
| |
| 10:10 | the fat clients use ldap user/pass
| |
| 10:11 | the pptp uses chap secrets for now
| |
| 10:12 | <vmlintu_> I have been using only openvpn tunnels
| |
| 10:12 | but not on fat clients
| |
| 10:13 | <dobber> it's not a big difference if you have to edit the initrd
| |
| 10:14 | i wonder, why ltsp wants to have network up in initrd :(
| |
| 10:14 | before init
| |
| 10:14 | it complicated the process a lot :(
| |
| 10:14 | <ogra_> init brings up the network in ltsp
| |
| 10:14 | its not *before* init
| |
| 10:15 | and it needs to be up in initrd because the rootfs is mounted from a remote location over the network
| |
| 10:16 | <vmlintu_> do you want to tunnel the rootfs connection?
| |
| 10:17 | <dobber> yes
| |
| 10:17 | i'm booting from usb stick
| |
| 10:17 | i have this line in sysconfig
| |
| 10:17 | APPEND ro root=/dev/ram0 ramdisk_size=204800 looptype=squashfs loop=/oneiric.img cdroot initrd=/initrd.img nbdport=2002
| |
| 10:18 | in the local network with dhcp it's working perfectly
| |
| 10:18 | but i need to be able to boot it outside the network
| |
| 10:18 | and i have given up on trying to start up wireless connection in the initrd
| |
| 10:19 | <ogra_> that would be highly insecure
| |
| 10:19 | <dobber> probably
| |
| 10:19 | <ogra_> since you would have to put the WEP key in there .... and given anyone in your network can then download and unpack the initrd ...
| |
| 10:20 | .... you could as well go with a fully open network
| |
| 10:20 | <dobber> well i would love to be able to put a curses network manager to configure the network
| |
| 10:20 | so i don't have to hard-code user/pass in initrd
| |
| 10:22 | markit has joined IRC (markit!~marco@151.78.74.112) | |
| 10:24 | <dobber> but it's too hard and i've given up
| |
| 10:24 | <markit> hi, I've a really bad situation with server freezing (kubuntu 11.04) while 22 clients using impress, but don't know if is related to impress or not. Sometime it freezes when printing. I'm not at school, I've been referred by a teacher. What is the first thing to check? what log? what config? 12GB ram in the server isn't enough? tons of free hd space

| 10:37 | alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg) | |
| 10:48 | <alkisg> dobber: in oneiric you should have network manager running in ltsp fat clients, so you should be able to create and use vpn connections "normally"
| |
| 10:48 | But I think that in your case, I'd go with usb ltsp booting + x2go
| |
| 10:49 | <dobber> alkisg: what is x2go>
| |
| 10:49 | ?
| |
| 10:50 | <alkisg> !x2go
| |
| 10:50 | <ltsp`> alkisg: Error: "x2go" is not a valid command.
| |
| 10:50 | <dobber> how do i start the network manager ?
| |
| 10:51 | <alkisg> !learn x2go as x2go is an NX-based suite of applications that allow logging in to a remote X server from any OS. It's much more efficient than VNC over slow network. More info: http://www.x2go.org/
| |
| 10:51 | <ltsp`> alkisg: The operation succeeded.
| |
| 10:52 | <alkisg> The network manager should already be started on boot
| |
| 10:52 | so you'd only need to drop a connection in /etc/NetworkManager/system-connections
| |
| 10:53 | dobber: can you describe your end goal/use case in more detail?
| |
| 10:53 | <dobber> ok, do you guys want to start a thread somewhere
| |
| 10:53 | because it's getting to branched up
| |
| 10:54 | my goal is to give usb sticks to my co-worker so they can work from home
| |
| 10:54 | * ogra_ would go with just having a local install in these then | |
| 10:54 | <dobber> but i don't trust their windows (key loggers, etc) so i want to boot from the usb
| |
| 10:55 | start the vpn and they would be able to work as if they were in office
| |
| 10:55 | <alkisg> Then a normal (non-ltsp) usb stick + x2go sounds fine
| |
| 10:55 | <dobber> with their ltsp profiles
| |
| 10:55 | <ogra_> (probably with a preconfigured vpn setup and a preconfigured user with autologin or so)
| |
| 10:55 | <alkisg> x2go uses ssh, so you don't really need a vpn
| |
| 10:56 | <ogra_> right
| |
| 10:56 | if you go with x2go :)
| |
| 10:56 | <dobber> i don't need autologin in ltsp, they should be able to use their user/pass
| |
| 10:56 | <alkisg> All this has nothing to do with LTSP. An x2go (and all other NX variants) perform much better over ADSL etc than X windows, VNC etc
| |
| 10:57 | So I don't think you need to be looking at LTSP for your use case
| |
| 10:58 | <dobber> x2go is a bootable linux with X client that can connect to ltsp server ?
| |
| 10:58 | <alkisg> No
| |
| 10:58 | You need two parts
| |
| 10:58 | 1) bootable part
| |
| 10:58 | 2) remote X part
| |
| 10:58 | x2go is (2)
| |
| 10:58 | For (1), you can use any linux version, live usb stick or not...
| |
| 10:58 | andygray has joined IRC (andygray!~andy@h44.212.22.98.dynamic.ip.windstream.net) | |
| 10:59 | <dobber> when do I start x2go ? Instead of X ?
| |
| 10:59 | <alkisg> Do you know about windows remote desktop?
| |
| 10:59 | <dobber> yes
| |
| 10:59 | <alkisg> rdesktop, xfreerdp etc?
| |
| 10:59 | It's like that, only for linux
| |
| 10:59 | So the usb stick boots normally, displays X and all
| |
| 10:59 | <dobber> i see
| |
| 10:59 | <alkisg> And then you click on x2go and launch it full screen
| |
| 11:00 | And if you want you can put it in autostart items etc etc
| |
| 11:00 | <dobber> but then all application will start from the ltsp server, not the client
| |
| 11:00 | <alkisg> Yes
| |
| 11:00 | Once you run x2go, you're in the ltsp server after that
| |
| 11:01 | <dobber> well i'll give it a try
| |
| 11:01 | but i have lots of apps configured to run locally
| |
| 11:02 | i dunno if this is going to work, let me try the mac client now
| |
| 11:04 | i can't connect
| |
| 11:04 | <alkisg> If you prefer ltsp fat clients over x2go, you can write the whole ltsp chroot in a stick
| |
| 11:05 | You'd need to change the initramfs just a bit for that to work
| |
| 11:05 | Then the login + /home can be as usual, over ssh
| |
| 11:05 | <ogra_> would you ? you should eb able to use a local lts.conf, no ?
| |
| 11:06 | <dobber> guys, i can't test fast enough
| |
| 11:06 | i installed x2goclient on my mac
| |
| 11:06 | but it fails to connect
| |
| 11:06 | <alkisg> Did you install the server too?
| |
| 11:07 | <ogra_> do you have a server installed on the other side ?
| |
| 11:07 | <dobber> on my ltsp server ?
| |
| 11:07 | <ogra_> indeed
| |
| 11:07 | <dobber> nope
| |
| 11:07 | <alkisg> OK, read the x2go docs first, and if you can't find out how to use it, try their mailing list
| |
| 11:07 | Steve_The_Pirate has joined IRC (Steve_The_Pirate!~Gary@CPE-124-189-0-222.iacz1.cht.bigpond.net.au) | |
| 11:07 | <alkisg> x2go is fast for remote X
| |
| 11:07 | But fat clients should be faster, of course
| |
| 11:09 | <dobber> the problem is that the network is started from /usr/share/initramfs-tools/scripts/init-premount/udhcp
| |
| 11:09 | and if it can't work with lan+dhcp it stops
| |
| 11:09 | so there is no network manager there
| |
| 11:10 | <alkisg> In 12.04 that was solved, if booting locally then udhcpc does nothing
| |
| 11:10 | You could either backport the fix, or pass a temporary specific ip=x:x:x:x:x in the kernel command line
| |
| 11:10 | <dobber> i'm on 11.10 still
| |
| 11:10 | <alkisg> Network manager is started after the initramfs stage

| 11:15 | toscalix has joined IRC (toscalix!~toscalix@252.174.219.87.dynamic.jazztel.es) | |
| 11:31 | <dobber> do i need to mount the rootfs in the initrd if i have my image on the usb stick
| |
| 11:33 | <alkisg> Yes the initramfs always needs to mount the rootfs, LTSP or not.
| |
| 11:34 | <dobber> i mean, the ltsp rootfs
| |
| 11:34 | if i have my onieric.img with the usb
| |
| 11:34 | <alkisg> Yes
| |
| 11:35 | <dobber> so i can mount the onieric.img localy and skip networking
| |
| 11:35 | for later
| |
| 11:35 | <alkisg> Yes

| |
| 13:27 | x2go is ok-ish but it's not ltsp
| |
| 13:27 | dead_inside has joined IRC (dead_inside!~dead_insi@76.75.3.174) | |
| 13:27 | <dobber> so i have to use different server for it
| |
| 13:33 | <alkisg> A discussion forum for x2go or for how to boot ltsp from a stick?
| |
| 13:33 | For the latter, you might get some answers from the mailing list, or you might just wait a couple of months until I properly implement it, we're halfway there now
| |
| 13:34 | <dobber> maybe i'll help then
| |
| 13:34 | http://pastebin.com/avxAkZ0q
| |
| 13:34 | is this a proper sequence ?
| |
| 13:35 | <alkisg> No
| |
| 13:36 | Moment, need to clean something up...
| |
| 13:45 | dobber: I imagine it like this:
| |
| 13:45 | 1) Tell your users to run win32loader.exe from windows
| |
| 13:46 | That's a debian project that aims for easy debian installation
| |
| 13:46 | It downloads the kernel from some site
| |
| 13:46 | ==> you can tell it to fetch your ltsp kernel+initrd if you put them somewhere
| |
| 13:46 | 2) Tell your users to copy /opt/ltsp/images/i386.img in their windows hard disks
| |
| 13:47 | Steps 1 and 2 can also be done with a usb stick, but I find it easier this way ^
| |
| 13:47 | <dobber> alkisg: we want usb sticks because of keyloggers on windows
| |
| 13:47 | <alkisg> Keyloggers won't run since it'll be linux
| |
| 13:47 | A linux kernel and a loopback linux image
| |
| 13:48 | So nothing windows-related is loaded
| |
| 13:48 | <ogra_> you could install a linux keylogger indeed (thogh you first have to write one i guess)
| |
| 13:48 | <alkisg> But if you really really want a usb stick, the principal is the same, a bootloader, the kernel+initrd, and the i386.img image
| |
| 13:48 | Now, the kernel command line would have to have something like:
| |
| 13:49 | root=UUID or LABEL, the label of the hard disk or usb stick where the i386.img resides, and init=/sbin/init-ltsp, the regular 12.04 way to select an ltsp boot
| |
| 13:50 | So at that point udhcp sees that nbdroot isn't selected, so it doesn't bring up the network,
| |
| 13:50 | the normal initramfs mounts the disk at /root,
| |
| 13:50 | and the local-bottom/ltsp script then has one task to do, which is the part that isn't implemented yet:
| |
| 13:51 | Check yet another kernel parameter, e.g. ltsp-loopback=/path/to/i386.img,
| |
| 13:51 | locate it in /root/path/to/i386.img,
| |
| 13:51 | loop mount it, and mount --bind it to /root, so that's the new root
| |
| 13:51 | That's all, then it exits and everything works as normal
| |
| 13:51 | (that was step 3)
| |
| 13:52 | <ogra_> wh not mount --move ?
| |
| 13:52 | *why even
| |
| 13:52 | <alkisg> Details... :D
| |
| 13:52 | <ogra_> :)
| |
| 13:52 | <alkisg> True, --move
| |
| 13:52 | Now about the networking part,
| |
| 13:52 | you don't need wicd or anything
| |
| 13:52 | Network manager runs fine without X, and connects automatically to any system connections defined as "auto start"
| |
| 13:53 | So you just need to create one such connection, and copy it to your chroot, and run ltsp-update-image, _before_ telling your users to download i386.img
| |
| 13:53 | <dobber> what if i'm on unknown wifi network
| |
| 13:54 | s/i',m/they are/
| |
| 13:54 | <alkisg> Then you could run the network manager connection editor for them from ldm
| |
| 13:56 | You could also allow them to login completely locally with a guest account, with full access to network manager, so that they set up any network connection they like, if they know how
| |
| 13:57 | And if you go too far, you can even have some persistence there, to allow the network connections to persist across reboots
| |
| 13:57 | Work time, bbl
| |
| 13:57 | <dobber> well let's sort the booting time for now
| |
| 13:58 | <alkisg> (will read irc logs when I come back)

| 18:01 | <Zen_> anyone hanging out here to answer some LTSP questions?
| |
| 18:01 | <alkisg> !ask
| |
| 18:01 | <ltsp`> alkisg: ask: Don't ask to ask a question, simply ask it, and if someone knows the answer, they'll respond. Please hang around for at least 15 minutes after asking a question, as not everybody constantly monitors the channel.
| |
| 18:06 | <Zen_> I was looking at ltsp-cluster but there does not seem to be any news or updates since 2010 so I was wondering how alive that project is.
| |
| 18:07 | https://www.revolutionlinux.com seems to be offering services around it but it's not clear what version that is.
| |
| 18:08 | <alkisg> I think they're the ones maintaining it, so they should support the latest version
| |
| 18:08 | <Zen_> I was looking at implementing a 10-15 seat setup for both a small local school in Costa Rica as well as double it as an internet cafe.
| |
| 18:08 | vagrantc has joined IRC (vagrantc!~vagrant@75-150-46-245-Oregon.hfc.comcastbusiness.net) | |
| 18:09 | <alkisg> Hang around, they may answer, if not, try other hours to find them online or use their contact pages etc
| |
| 18:09 | Why would you need a cluster just for 10-15 seats?
| |
| 18:09 | <Zen_> the ltsp-cluster page pointed me to this IRC channel
| |
| 18:10 | <alkisg> I believe cluster is for multi-server setups, with hundreds of users etc
| |
| 18:10 | For smaller setups, plain LTSP is fine
| |
| 18:10 | <Zen_> right.. that was my next question... would I need a cluster even for such a small project other than longer term easier managment and to learn ltsp cluster.
| |
| 18:11 | Once I learn it, there are other projects on the table I can implement which would service call centers.
| |
| 18:12 | can a 10-20 seat call center be run by a normal LTSP on a box with 8 cores ?
| |
| 18:13 | <alkisg> Sure
| |
| 18:13 | And if you run the phone app as a localapp, a single core would also do
| |
| 18:13 | *single core server
| |
| 18:14 | <Zen_> phone app meaning a soft voip client?
| |
| 18:14 | <alkisg> Yes, whatever you need to run on the clients
| |
| 18:16 | <Zen_> for the language school, we want to make use of Rosetta Stone language software which runs on windows/wine. Does winehq generally run fine on a LTSP setup?
| |
| 18:16 | <alkisg> For some apps, wine can be a bit slow over the network, but if your clients are good enough to run it as a localapp, it runs normally then
| |
| 18:17 | If that software doesn't have many screen updates, I imagine it'll run just fine either way
| |
| 18:21 | <Zen_> you know if there any pre-made virtua lmanchines appliances for openvz containers with a LTSP setup installed ready to go?
| |
| 18:22 | <alkisg> No idea, but the edubuntu live dvd does have an ltsp live functionality
| |
| 18:24 | <Zen_> ltsp-cluster has OpenVZ info but as suggested, maybe using cluster overcomplicates this. I will do some more research. Thanks for your tiem and answers provided so far. :)
| |
| 18:25 | <talntid> so, in a further effort to optimize my LTSP setup, I have determined my memory/CPU usage is very low, but... my loads are still around 6-8.... I have 36 users, and 7cores, 8gb ram
| |
| 18:26 | I'm being bottlenecked by network performance right now
| |
| 18:26 | would disabling compression help me out? My thin clients are nfsmounted to a remote file server, for what it is worth. but they are on the same network, connected by gigE
| |
| 18:26 | <alkisg> talntid: btw do you have ldm_directx=true?
| |
| 18:26 | <talntid> checking
| |
| 18:27 | <alkisg> !directx
| |
| 18:27 | <ltsp`> alkisg: directx: If you want to turn off encryption to the workstation, which will speed up performance at the cost of security, you need to specify LDM_DIRECTX=True in your lts.conf file. Type !docs in IRC to get a link to the current documentation
| |
| 18:28 | <talntid> ahh, suhweet.

| |
| 19:03 | etc
| |
| 19:03 | <markit> btw, epoptes log is 1.6MB...
| |
| 19:04 | <alkisg> markit: thin or fat clients?
| |
| 19:04 | <markit> yep, but the problem is that the server (and so all teh clients) are frozen
| |
| 19:04 | thin client
| |
| 19:04 | 12GB ram, 22 clients
| |
| 19:05 | <alkisg> That's when printing?
| |
| 19:05 | (the server freeze)
| |
| 19:05 | <markit> btw, this day but don't know if at this hour, in epoptes log I have 2012-04-17 08:40:08+0200 [-] Ping timeout!
| |
| 19:05 | alkisg: has been when printing, today I don't know, for sure they put a child on the server
| |
| 19:05 | <alkisg> That's no big deal, it happens whenever a client closes without closing the network connections first
| |
| 19:05 | <markit> that is like put a passenger to pilot the airplane...

| 19:06 | <alkisg> Problems in server modules can crash the server of course, but those problems aren't related to LTSP...
| |
| 19:07 | <markit> alkisg: I already told you about it but I thought GNU/Linux was rock solid, while I see it hardly usable for multiuser
| |
| 19:07 | <talntid> alkisg, you maintain epoptes, right?
| |
| 19:07 | <markit> alkisg: here I've the log of the entire server, if you want a zip of them...
| |
| 19:07 | <alkisg> Nope
| |
| 19:08 | <talntid> ah, ok
| |
| 19:08 | <alkisg> I can't help with module problems
| |
| 19:08 | You should file a bug on the linux kernel if they're embedded
| |
| 19:08 | Or to HP if it's about the printer module you installed
| |
| 19:08 | <markit> alkisg: hehe, hp has "unsupported" linux drivers
| |
| 19:08 | <alkisg> Then don't buy from them :)
| |
| 19:08 | <markit> they provide for Windows and Mac, but for "poor stupid foss people" is to thank that they give us drivers
| |
| 19:08 | <talntid> being that is the case, your options are......... alkisg hit the nail on the head
| |
| 19:09 | haha
| |
| 19:09 | <markit> impossible pretend that they also work reliable
| |
| 19:09 | Phantomas has joined IRC (Phantomas!~Phantomas@unaffiliated/phantomas) | |
| 19:09 | <markit> alkisg: hp is the "less worse"
| |
| 19:09 | alkisg: out of rant...
| |
| 19:09 | do you have a "stress test" for ltsp?
| |
| 19:10 | <alkisg> Anyway, all this is unrelated to LTSP and even to GNU/Linux as you keep saying it :D
| |
| 19:10 | I usually test with video broadcasting
| |
| 19:10 | Fullscreen
| |
| 19:10 | There's also a "stress" utility
| |
| 19:10 | <markit> good idea
| |
| 19:11 | but video broadcasting is vnc with epoptes
| |
| 19:11 | would love to have a graphical program run indipendently from vnc stuff
| |
| 19:11 | that can act as test
| |
| 19:11 | <alkisg> No vnc
| |
| 19:12 | I select the clients with epoptes and run a command with the execute dialog:
| |
| 19:12 | <markit> video broadcasting with vlc?
| |
| 19:12 | <alkisg> totem /home/teacher/Public/video.avi
| |
| 19:12 | -fullscreen, even
| |
| 19:12 | <markit> oh, you know you have to be very explicit with me :)
| |
| 19:12 | <alkisg> And if I want to stress the network, I run iperf -s on the server, and iperf -c server on the clients
| |
| 19:12 | <markit> ok, I'll test tomorrow this way
| |
| 19:13 | thanks a lot for the tips
| |
| 19:13 | <alkisg> np
| |
| 19:14 | <markit> btw, I've seen you talking about x2go today... is working fine? something worths try and use?
| |
| 19:14 | (for remote connection)
| |
| 19:14 | and would it be a good idea for epoptes remote help instead (or in addition to ) vnc?

| 19:17 | <muppis> !win32-loader
| |
| 19:17 | <ltsp`> muppis: win32-loader: win32-loader.exe can be used to add a "PXE - Network boot" option to the Windows boot manager. It's developed for Debian and it uses gPXE/iPXE for the network booting. You can download a binary from http://ftp.debian.org/debian/tools/win32-loader/unstable/ (if someone can write a wiki page about it it'd be nice :))
| |
| 19:19 | <alkisg> markit: x2go works fine, yes, it's one of the few opensource nx implementations that are still maintained
| |
| 19:20 | No it wouldn't help with epoptes, as x2go relies on vnc too for local screen sharing
| |
| 19:22 | <markit> alkisg: I meant for REMOTE help
| |
| 19:22 | ssh, vnc and x2go
| |
| 19:22 | <alkisg> markit: remote help means sharing the local user display
| |
| 19:23 | Local == one where the user has a monitor and a keyboard and a mouse
| |
| 19:23 | As opposed to a "virtual" one, when you connect with NX to a remote server
| |
| 19:23 | risca has left IRC (risca!~risca@wnpgmb0903w-ds01-249-233.dynamic.mtsallstream.net, Quit: Lämnar) | |
| 19:23 | <alkisg> So there, x2go uses vnc
| |
| 19:23 | x2go: vnc+ssh
| |
| 19:23 | epoptes: vnc+ssl
| |
| 19:23 | ...so no benefit to use x2go too
| |
| 19:25 | <markit> no nx?
| |
| 19:25 | * markit confused | |
| 19:25 | <alkisg> x2go uses nx too, yes
| |
| 19:25 | <markit> I mean, the teacher is in troubles and asks for help... now epoptes uses ssh or vnc, but NX protocol should be much faster
| |
| 19:25 | <alkisg> vnc+ssh+nx
| |
| 19:26 | Yes x2go in that case uses vnc too. vnc for local display access, and nx/ssh to transfer the screen.
| |
| 19:26 | So it's slower than normal x2go operation
| |
| 19:27 | I don't think it's worth the trouble to integrate that to epoptes
| |
| 19:27 | Because then ssh authentication would be needed, etc
| |
| 19:27 | If one wants to do it he can do it directly with x2go
| |
| 19:30 | <markit> got it, thanks

| |

| |

| |
| 19:45 | that doesn't necessarily sound like a LTSP issue.
| |
| 19:46 | can you print from the server reliably?
| |
| 19:47 | Phantomas has joined IRC (Phantomas!~Phantomas@unaffiliated/phantomas) | |

| |
| 19:48 | alkisg has left IRC (alkisg!~alkisg@ubuntu/member/alkisg, Quit: Leaving.) | |

| 19:58 | <markit> to be sincere, having one student print something and all the class frozen is far from reassuring experience
| |
| 19:59 | <||cw> is the server single core? is it doing bitmap printing, eating all the ram?
| |
| 20:14 | <markit> ||cw: is i7 quad core with 12 gb ram
| |
| 20:14 | but looking at the logs, seems that the printer gets "disconnected" or has errors in communication
| |
| 20:14 | cups log is scaring
| |
| 20:15 | at a certain point, I suppose the one of the froze, I've tons of lines
| |
| 20:15 | <||cw> I've seen usb inkjets hog cpu and ram before, but an i7 should handle that
| |
| 20:15 | <markit> E [17/Apr/2012:11:34:49 +0200] [Job 1726] Unable to queue job for destination "ipp://gnuserver/printers/HP-Color-LaserJet-CM2320nf-MFP"!
| |
| 20:15 | <||cw> usb comms flipping out is another story though
| |
| 20:16 | hm, ipp is tcp/ip, not usb
| |
| 20:16 | <markit> well, it's connected with usb for sure
| |
| 20:16 | <||cw> so this is a thin client printing from a localapp?
| |
| 20:17 | <markit> "DEVICE_URI=hp:/usb/HP_Color_LaserJet_CM2320nf_MFP?serial=00CNFTB3PJL5"
| |
| 20:17 | ||cw: no, thin client printing from a "normal" app, impress that runs on the server
| |
| 20:17 | <||cw> if it has ethernet, you are better off using it instead
| |
| 20:18 | that should not be printing using ipp, when its config'd for usb
| |
| 20:19 | ethernet is faster than usb in reality, and that printer is big enough that it'll suck in most jobs to its interal queue over the lan. not sure the same would be true on usb
| |
| 20:20 | <markit> I had not spare cable to connect with the switch, but now the situation has improved and I could try
| |
| 20:21 | btw, often printers go "off line" due to a simple problem (i.e. out of paper) and you have to manually put online
| |
| 20:21 | with HP control tray icon
| |
| 20:21 | but if you don't have it, you have to use cups web interface
| |
| 20:21 | is it possible to configure them not to go "on hold"
| |
| 20:21 | or whatever that state is called?
| |
| 20:21 | <||cw> huh, I haven't see that, but I don't think I have any usb connected lasers
| |
| 20:22 | <markit> is very very annoying
| |
| 20:22 | <||cw> normally you just push the green button on the printer's panel and it starts up again
| |
| 20:25 | <markit> if I press it, it (my father's one) switches off :)
| |
| 20:31 | <||cw> o_O wrong green button?
