<Hyperbyte>
mhm
07:24
If only he'd have mentioned what OS/browser he was using...
07:32
<knipwim>
hey Hyperbyte, a bit offtopic question
07:33
but how do you reply to a mailinglist topic when you're not a subscriber
07:33komunista has left IRC (komunista!~slavko@adsl-195-168-234-074.dynamic.nextra.sk, Read error: Operation timed out)

<knipwim>
and i don't want to send at the end of the thread
07:39
<Hyperbyte>
You can't send any e-mails to mailing lists if you're not subscribed, reply or otherwise.
07:40
Else mailing lists would be spammed to death... imagine sending one e-mail to an address, and thousands of people receiving it
07:40
That'd be awesome for spammers.
07:41
<knipwim>
To post a message to all the list members, send email to openchrome-users@openchrome.org
07:41
without subscribing
07:42
so i figured i could reply to a topic
07:43
it's so frustrating
07:43
why isn't there a unified bug/forum system, one architecture/login system for all these projects

<markit>
hi alkisg, a short report of yesterday and today... I've re-installed from scratch ltsp on a server using your repo
16:24
<alkisg>
Hi markit
16:25
<markit>
with kde and nfs I've kdeinit4 and kmix crashing
16:25
with sshfs not
16:25
as far as I remember, with "normal" ltsp repo I had problems with sshfs and not nfs...
16:25
unfortunately when you work short in time and very stressed
16:25
is hard have a clear picture of what you are doing
16:25
<alkisg>
I don't think the newer ltsp version has anything to do with sshfs vs nfs
16:26
<markit>
me too, I just report facts, I'll have to do more experiment but using kde seems a real problem
16:26
<alkisg>
But here we let sshfs which is the default, and we're not using nfs anymore
16:26
<markit>
today I turned on all 18 fat clients, only 17 were on epoptes
16:26
<alkisg>
Also atheros NICs had problems with NFS, they required special nfs options
16:27
<markit>
I restarted the "faulty" one (that worked fine on it's own, I could login with an user and work)
16:27
<alkisg>
Try `epoptes-client` manually from pc18 and check for errors
16:27
<markit>
and nothing... at the 3° restart it appeared
16:27
alkisg: let me ask this about exports
16:27
I used this line: /home *(rw,sync,no_subtree_check)
16:28
since I had teh kdeinit4 error, I googled and I've found a lot of ltsp related articles using this one instead
16:28
'/home *(ro,no_root_squash,async,no_subtree_check)
16:28
<mjt>
blah
16:28
<markit>
but with this, I can't even have the deskotp
16:28
<alkisg>
ro home? That doesn't sound ok
16:28
<markit>
ah!!!
16:28
I did not noticed, lol
16:29
that explains the lnusercache (infamous) error I got
16:29
<mjt>
no_root_squash is when you want to login as root remotely
16:29
i don't think this is what you want :)
16:30
<markit>
that's the power of google and ignorance combined ;P
16:30
<mjt>
(ie, so processes running on client as root have all root powers on your server)
16:30
<markit>
and my luck to find the wrong article in top position
16:30
<alkisg>
markit: btw, did you know there's an ubuntu-defaults-it package, with which you can build localized ubuntu live CDs, that contain all the italian langpacks? (and, if you want, also the greek schools ppa...)
16:31
<markit>
alkisg: interesting if I had time... I've found that live cd or usbkey look good, but the teachers I've to talk with are too ignorant
16:31
to get the concept
16:31
they try to open it in windows and complain "it does not run"
16:31
even if I carefully explained them and show how to boot from cd in their laptop
16:32
I was shocked :(
16:32
computer IS windows
16:32
it's what you need to run whatever program or OS or whatever
16:32
alkisg: reading back to what you said
16:32
no nfs anymore????
16:33
also I've found your repo ltsp version has no --arch= parameter, correct?
16:33
<alkisg>
We're not using nfs by default anymore, no
16:33
<markit>
alkisg: time ago you told me that nfs had advantaces over sshfs, has things changed in the meantime?
16:33
<alkisg>
markit: ltsp-update-image <arch>
16:34
The --arch parameter was dropped, it's only there in ltsp-build-client now
16:34
<markit>
(is not "accusation", just to understand what is going on)
16:34
<alkisg>
NFS is supposed to be faster, it has less problems, it's a real filesystem instead of a fuse-based one etc
16:34
So yeah it's supposedly better, BUT
16:35
It had problems with some NICs like Atheros that made /home unmountable,
16:35
And, it didn'd allow for "follow symlinks", which is very handy for shared folders
16:35
<markit>
(thought atheros produced only wifi chipsets)
16:35
<alkisg>
So, since usually under /home we don't care much about the special file system attributes/locks/whatever, we switched to the default sshfs, and we don't have any complains _yet_
16:36
We'll see over time if it was the correct decision to make
16:36
atl1c, atl1e etc are atheros wired ethernet cards
16:36
And they completely hanged unless you provided specific nfs options
16:37
(something about frame size, I don't remember exactly)
16:37
Also, upstart had problems with portmap, and required "nolock" in nfs options
16:37
That was another drawback for nfs
16:37
<markit>
I see... I have problems with cache of kde and SSH_FOLLOW_SYMLINKS, don't remember if is true or false
16:37
dinner time, thanks a lot for the info
16:37
see you later :)
