| HedgeMage | How are you tonight, Ahmuck_Sr | 03:48 |
| Ahmuck_Sr | a bit of a headache | 03:51 |
| Ahmuck_Sr | kinda feeling foggy | 03:51 |

| sbalneav | Morning all | 15:00 |
| alkisg | For non-LTSP labs with new PCs with lots of hard space, would NFS or AFS be a better choice (along with LDAP of course), if we want the users to be able to sit in any workstation and work with their files? | 15:41 |
| alkisg | (each labs has about 8-12 PCs) | 15:42 |
| nubae|work | alkisg, try and let us know :-) | 16:06 |
| alkisg | nubae|work: I'm searching for a way to organize non-ltsp labs... do you have any links that explain how you do things there? | 16:06 |
| alkisg | E.g. I was thinking the standard NFS / LDAP combination, but like you, some labs here don't have reliable network | 16:07 |
| alkisg | ...so I'm also thinking of developing scripts that rsync dirs at logon... | 16:08 |
| sbalneav | I've never used AFS myself. | 16:08 |
| alkisg | People at #openafs told me it's not really a good choice for home directories. So I guess I can scratch that.... | 16:09 |
| sbalneav | NFS has a laundry list of problems, but they're well known problems. :) | 16:09 |
| sbalneav | Ah, did they say why? | 16:09 |
| sbalneav | I use NFS form $HOME | 16:09 |
| alkisg | Yes, it's mostly for many servers - not much benefit if you use it with one server, | 16:10 |
| alkisg | and it can only expose 1 volume RW, and lots of others RO, so it won't be able to function as a distributed system between the clients PCs (that's how I had imagined it reading their wiki) | 16:10 |
| alkisg | sbalneav: do you think NFS would be a reliable choice for small labs? Or should I try to make scripts that use sshfs or rsync? | 16:11 |
| sbalneav | I have about 120 users running off of an NFS server here. | 16:12 |
| sbalneav | It's definitely workable. | 16:12 |
| sbalneav | 2 things you need to make NFS as pain-free as possible. | 16:12 |
| sbalneav | 1) A kick-*ss IO subsystem on the server. I.e. 6 disks RAID10 or better, Go SAS SCSI or better. Don't cheap-out on this. | 16:13 |
| sbalneav | 2) Gigabit interconnect for the servers. | 16:13 |
| nubae|work | alkisg, we have a little nfs hack here that makes it much more reliable | 16:13 |
| sbalneav | Oh? | 16:13 |
| nubae|work | kind of a a local/server cache addition | 16:14 |
| sbalneav | Do tell | 16:14 |
| sbalneav | AAAAHHHHHHGH! | 16:14 |
| sbalneav | http://radiocontempo.files.wordpress.com/2009/03/hrp_4c_6.jpg | 16:14 |
| alkisg | sbalneav: each lab here has only 1 server and 8-12 clients. So I guess I don't really need (2)... but, | 16:14 |
| sbalneav | Japan terrifys me yer again. | 16:14 |
| ogra | AFS is great but enforces you to have at least three reliable nodes constantly online | 16:14 |
| sbalneav | yet again | 16:14 |
| nubae|work | basically just synching based on cron or when the user wants | 16:14 |
| alkisg | suppose I use NFS and LDAP. And the server crashes. Is there *any* way for the clients to work even with *guest* users? | 16:15 |
| sbalneav | Sure | 16:15 |
| nubae|work | I would just use a fatclient ltsp setup then | 16:15 |
| sbalneav | Just don't put guest users on the NFS share. | 16:15 |
| nubae|work | with ldap | 16:15 |
| alkisg | So LDAP and /etc/passwd users can both be used simultaneously? And I just need to put the guest users in /etc/passwd with their homes in /home.local? | 16:16 |
| sbalneav | Yup | 16:16 |
| sbalneav | nsswitch.conf handles that. | 16:16 |
| alkisg | Nice!!! | 16:17 |
| nubae|work | yeah, with pam tweaking | 16:17 |
| sbalneav | You can have both local (/etc/passwd + local home) and remote (LDAP + NFS $HOME) | 16:17 |
| nubae|work | one before the other or the other before the one | 16:17 |
| sbalneav | Not much, and it's not difficult. | 16:18 |
| nubae|work | :-) | 16:18 |
| alkisg | nubae|work: unfortunately, not all labs have gigabit switches. E.g. this year I'm in a lab with core 2 duo / 2 Gb RAM / 400 Gb hd, with a *10 mbps hub* !!! | 16:18 |
| alkisg | ...so I'd like a non-fat client, non-ltsp choice... | 16:18 |
| nubae|work | well, its not really ltsp anymore | 16:18 |
| nubae|work | its more like netbooting | 16:18 |
| alkisg | No, I'm talking about local ubuntu installations | 16:18 |
| nubae|work | and booting is fine... it takes it little by little | 16:18 |
| nubae|work | works fine even over wireless | 16:19 |
| nubae|work | yes I know | 16:19 |
| nubae|work | netbooting and installing it then locally | 16:19 |
| nubae|work | or how were u thinking of cloning before hand?= | 16:19 |
| alkisg | I just tar'ed the first installation, burned it in a DVD, and untar'ed it... nothing over the network | 16:19 |
| nubae|work | thats fine, but when u have larger deployments.... | 16:20 |
| nubae|work | if u need to keep burning disks for every little change | 16:20 |
| alkisg | Sure, I'm *only* looking for a solution for 8-12 PC labs... | 16:20 |
| nubae|work | ur're gonna find it a pain | 16:20 |
| nubae|work | ah ok | 16:20 |
| alkisg | I'll be updating the PCs seperately, not by cloning them again | 16:21 |
| nubae|work | I had understood 8-12 pcs per lab | 16:21 |
| alkisg | Yes, e.g. 100 such labs | 16:21 |
| nubae|work | well clonezilla does a good job too | 16:21 |
| alkisg | But each one of them will be maintained by a different teacher | 16:21 |
| nubae|work | well, then definetly look at a solution that involves a netboot initial install... so the the user has a choice on what to install at startup over pxe | 16:21 |
| nubae|work | if u have that luxury of course | 16:22 |
| nubae|work | disks break, scratch, etc.. | 16:22 |
| alkisg | nubae|work: with 10 mbps hubs? That would take weeks... | 16:22 |
| nubae|work | at least... with 100 labs, I would not even consider dvds as an insallation mechanism | 16:23 |
| nubae|work | nah... | 16:23 |
| nubae|work | we do it here even with wireless | 16:23 |
| nubae|work | it doesnt take weeks, especially not on 8.-12 machines ;-) | 16:23 |
| alkisg | 10 mbps => 1 Mb/sec => 4000 minutes for cloning a 4 Gb installation | 16:23 |
| alkisg | for *one* pc | 16:23 |
| ogra | thats a lot of coffee breaks :) | 16:24 |
| nubae|work | all I can tell u is practically... it doesnt take that long | 16:24 |
| alkisg | nubae|work: how do you update/upgrade your clients? | 16:26 |
| nubae|work | net | 16:26 |
| alkisg | Cloning, or just apt-get update/upgrade etc? | 16:26 |
| nubae|work | mostly packaged | 16:26 |
| nubae|work | not cloning | 16:26 |
| nubae|work | that would indeed be unviable I think | 16:26 |
| nubae|work | needs to happen in bits | 16:27 |
| nubae|work | but perhaps a usb stick approach, nand, would be best | 16:29 |
| nubae|work | but nand has life issues | 16:30 |

| Ahmuck_Sr | is there Ubuntu for older people? | 19:35 |
| mhall119|work | regular Ubuntu doesn't work? | 20:06 |
| Guest8694 | Hello, I am having a problem with SCIM that I haven't been able to find help on | 23:43 |
| Guest8694 | I can only use it with Text Editor | 23:43 |
| Guest8694 | It should work with all GTK apps I believe | 23:44 |
| Guest8694 | I was here yesterday, also asked on Ubuntu, and Ubuntu Japan but didn't get anywhere | 23:44 |
| Guest8694 | I hope this sounds familiar to somebody | 23:44 |
