| 12:19 | <markit> hi alkisg, how are you? I have the need of backup user's account and restore in a different system with an updated OS. You told me you already have solved this issue, could you point me to the code so I can get "ispiration" of how do things properly?
| |
| 12:19 | I was thinking about a simple tar ignoring hiddend files/dirs (I don't want old configs)
| |
| 12:20 | then untar and re-issue user:group and ACL settings
| |
| 12:20 | of course, after re-creating the related user :)
| |
| 12:20 | <alkisg> Hi markit, to backup/restore user accounts we're using sch-scripts
| |
| 12:21 | We don't modify the file system, to take a backup for /home see one of the ubuntu wiki pages about backup
| |
| 12:21 | <markit> "We don't modify the file system" means?
| |
| 12:21 | <alkisg> Also we're not using ACLs, I couldn't see anything useful in them for our use cases
| |
| 12:21 | We don't do chown -R or ACLs or backup/restore /home etc
| |
| 12:21 | <markit> and is a particular file in sch-script? as far as I remember is commented in greek...
| |
| 12:22 | <alkisg> Phantomas is rewritting that part now, so the newer and better version isn't yet ready
| |
| 12:22 | (which has support for conflict resolution)
| |
| 12:22 | No, it's not one file, it uses libraries (libuser.py) etc, so you can't take 1 file and use it
| |
| 12:22 | komunista has left IRC (komunista!~slavko@adsl-195-168-231-072.dynamic.nextra.sk, Ping timeout: 272 seconds) | |
| 12:23 | <markit> regarding ACL, I implemented it to solve some issues you don't have or solve differently, I have to take a lot of time and rething the whole problem and re-reading our conversation on the subject that I took note about
| |
| 12:23 | btw, do you think is a suicide include the kubuntu/backport to have updated KDE in 12.04?
| |
| 12:24 | <alkisg> Backports are enabled by default in ubuntu afaik
| |
| 12:24 | <markit> yep, but not kubuntubackport
| |
| 12:24 | that brings you updated KDE
| |
| 12:24 | let me find the page
| |
| 12:24 | <alkisg> No idea there, I'm not using KDE
| |
| 12:25 | <markit> are you really using "unity"?
| |
| 12:25 | <alkisg> No, gnome-fallback, looks like the old 10.04 gnome panel
| |
| 12:26 | <markit> I see... I was wondering if a simple lxde could make sense instead of kde
| |
| 12:26 | <alkisg> Why not gnome-fallback?
| |
| 12:26 | It's light enough, and has the whole gnome backend to support it
| |
| 12:26 | <markit> will be removed soon, and I think lxde uses low resources
| |
| 12:26 | and I dislike gnome ;P
| |
| 12:26 | (remember me Incaza and M$ stuff)
| |
| 12:26 | <alkisg> When it's removed, cinnamon will probably be ready to switch there, which again looks like 10.04
| |
| 12:26 | <markit> remembers
| |
| 12:27 | lol, tradition over innovation
| |
| 12:27 | everyone loves XP ;P
| |
| 12:27 | <alkisg> LXDE does use low resources, but not a whole lot less than gnome-fallback, and that's because it's missing stuff
| |
| 12:27 | <markit> I see
| |
| 12:27 | <alkisg> If you don't care about that stuff, sure, you could use it
| |
| 12:28 | Gnome isn't directly related to mono or .net
| |
| 12:28 | Also, I'm a bit worried about how KDE will fare without the Qt commercial support
| |
| 12:29 | <markit> I have to use better my time and solve completely 12.04 stuff in my scripts, and update all the 3 installation I've done so far
| |
| 12:29 | time slips through my fingers so fast...
| |
| 12:29 | Qt is Free software, I've no fear
| |
| 12:29 | someone will pick it up
| |
| 12:29 | <alkisg> Check sf.net, 10.000 dead free software projects there
| |
| 12:30 | <markit> the main problem I see for FOSS is that people have to understand it and help/found it
| |
| 12:30 | yep, like gnome-fallback or it's successor
| |
| 12:30 | <alkisg> FOSS needs companies and money, otherwise it dies when the developer sees that he needs to find another job :)
| |
| 12:30 | <markit> whatever you choose, there is a risk
| |
| 12:31 | but Qt is widely used
| |
| 12:31 | FOSS needs dev to have it as "the job"
| |
| 12:31 | <alkisg> In nokia phones and KDE, where else?
| |
| 12:31 | <markit> with or better without companies that have different interests, mainly on user lock in
| |
| 12:31 | <alkisg> And nokia just killed it, it's firing the developers
| |
| 12:31 | <markit> nokia is a M$ company now, backrupt is near
| |
| 12:32 | <alkisg> With wayland and 3d acceleration and tables etc in the future, there needs to be some company behind such libraries, otherwise they get into low maintenance mode
| |
| 12:32 | *tablets
| |
| 12:33 | <markit> I know, even if I hate tablets and wayland
| |
| 12:33 | things are becoming worse and worse OMHO
| |
| 12:33 | but I'm a pessimistic ;P
| |
| 12:33 | <alkisg> Wayland is good, it'll give us an UI without 20 years of compatibility code + design
| |
| 12:34 | <markit> and kill LTSP and network X feature
| |
| 12:34 | <alkisg> And tablets are good too, I just don't like the fact that they're trying to merge the UIs
| |
| 12:34 | Why kill LTSP?
| |
| 12:34 | Fat clients work anywhere
| |
| 12:34 | And thin clients might be better off as zero clients
| |
| 12:34 | <markit> "zero clients"?
| |
| 12:35 | <alkisg> Yeah, google for pc over ip
| |
| 12:35 | I'm guessing hardware thin clients will be more common in the future
| |
| 12:35 | And that'll be a good thing, having hardware accelleration for remote UI
| |
| 12:35 | <markit> proprietary stuff?
| |
| 12:36 | well, we have so old pc in schools that hw acceleration will never come in 50 years ;P
| |
| 12:37 | <alkisg> Old hardware doesn't have many chances in the 3d DE era, with unity-3d, gnome-shell etc
| |
| 12:37 | Not with X anyway, maybe if another protocol emerges...
| |
| 12:37 | Anyway, time to get back to work :)
| |
| 12:38 | <markit> pnp-ltsp?
| |
| 12:38 | <alkisg> ltsp-pnp is just a way to maintain fat clients without a chroot
| |
| 12:38 | Nothing more...
| |
| 12:38 | <markit> or what else are improving? or maybe help wife with other stuff?
| |
| 12:38 | <baptiste> wayland allows a VNC-like remote use (whole screen as a bunch of tiles). so if you used a ltsp thin client that uses VNC, wayland maybe doesn't changes much
| |
| 12:39 | <alkisg> markit: yup, not computer related work :)
| |
| 12:39 | <markit> baptiste: vnc is very slow I think
| |
| 12:39 | alkisg: oh, what a suprise :) good work then, see you soon, thanks for the tips
| |
| 12:39 | <baptiste> markit, depends on the configuration. a buddy told ltsp to use VNC and it was very fast
| |
| 12:40 | <markit> baptiste: I really dubt you can serve 24 clients fast
| |
| 12:41 | <baptiste> 2 to 4 clients were fast, never got to test that many
| |
| 12:42 | Parker955_Away is now known as Parker955 | |
| 12:42 | <baptiste> never saw the q6600 CPU at 100% (or is it 400%) use either
| |
| 12:47 | Parker955 is now known as Parker955_Away | |
| 12:49 | <baptiste> btw I couldn't see a difference between 10Mbps and 100Mbps on the clients (pentium 2 233). if you have a big ethernet switch with 1Gb uplink that goes to the server, and the server is ridiculously powerful (which is cheap), shouldn't that support 24 clients whatever the hell you do? :)

| 12:55 | <baptiste> alkisg, did you look at nvidia VGX (graphics card with 4 GPUs, 16GB ddr3, no video ouput). up to 100 thin/remote client users
| |
| 12:56 | <alkisg> baptiste: no, I don't have access to any "real" thin client hardware, we're just reusing desktop pcs here....
| |
| 12:57 | <baptiste> that's server hardware. but tied to "real" thin clients, as you say
| |
| 12:57 | <alkisg> But I'm pretty sure special hardware can help thin clients. Although, if I were to buy new clients, I'd buy fats, not thins
| |
| 13:02 | <baptiste> is there an open protocol in the works.. you have things like microsoft RemoteFX, with 3D rendering encoded and beamed to thin clients, which use hardware decoding to show it
| |
| 13:03 | Phantomas has left IRC (Phantomas!~Phantomas@unaffiliated/phantomas, Ping timeout: 240 seconds) | |
| 13:03 | <baptiste> this seems great but pretty proprietary
| |
| 13:09 | now, if you make a fat from new hardware, it may have a celeron g530. this stuff is incredibly powerful and somwhat low power. I feel confused, can't believe it's true
| |
| 13:12 | thin beats it, only if you want to get _very_ low power, or if you use pre-pentium 4 old computers

| 13:14 | * alkisg would like anything with >= 1 Gb RAM from that page :) | |
| 13:15 | <alkisg> No need for fancy protocols like remotefx with fat clients, as they work like regular installations...
| |
| 13:16 | Redhat is developing SPICE, but I haven't tried it

| 13:26 | <baptiste> I find this thin client pretty interesting, though old, very slow CPU and made to run with a windows server http://www.norhtec.com/products/mctc/index.html
| |
| 13:26 | * baptiste would like a chinese SoC with hardware decode for a fancy protocol, costing peanuts | |
| 13:34 | <alkisg> We might even see them embedded in monitors in the future :)
