14:37
I have no idea about IRC bots really, but have lots of servers available which I could give someone shell access to to run one.
14:40
I figured someone should still have all the stuff needed for ltspbot, I could just move it onto a shell somewhere and help out
14:44
<Gnoze5>
ltspbot?
14:44
Hyperbyte, theres an ltspbot?
14:45
<Hyperbyte>
There was. =)
14:45

ah
14:45
what exactly did it do?

ok, i am having serious issues
19:06
when a client boots to my ltsp server it doesn't load the normal template and i cant click anything
19:06
i can log in, but after that it wont let me click any menus
19:07
it basically locks the client

<Gnoze5>
TheMatrix3000
20:28
still having the same issue?
20:30
<TheMatrix3000>
yes
20:30
but i think i figured it out
20:30
it's a permissions issue with the nfs /home mount from teh freenas server
20:30
I don't think I can use freenas for this implementation
20:30
because of how secure freenas is
20:31
<Gnoze5>
zfs + bsd?
20:32
<TheMatrix3000>
yea
20:32
lol
20:32
i mounted the directory
20:32
and it would mount, its just each folder got the wrong user permissions
20:32
and changing it did nothing
20:38
<Gnoze5>
btw what did you install FreeNAS on?
20:44
<TheMatrix3000>
4x500GB server
20:44
running raidz2
20:44
on zfs
20:53
Gnoze5: you have any ideas to get it to work, or should I just reformat and install Ubuntu on that sytsem
20:55
<Gnoze5>
indeed im not master of any of the implications
20:55
but im pretty sure that you can use FreeNAS
20:55
i see no reason why you wouldnt be able to

alkisg good morning my friend
20:56
<alkisg>
Good morning :)
20:56
<Gnoze5>
TheMatrix3000 is trying to use FreeNAS with ltsp
20:59
TheMatrix3000 at the end of the day its just storage
20:59
<alkisg>
Connecting the LTSP server to a freenas server shouldn't be LTSP related... right?
21:00
<TheMatrix3000>
well, its the ltsp users
21:00
not getting the right permissions
21:00
should they be mounted cilentside or server side /home
21:00
<alkisg>
If you logon to the server directly with a user, does he get the correct permissions?
21:01
<TheMatrix3000>
yes, the server has it, but the mount isn't getting it
21:01
it's part ltsp part server part freenas related
21:01
lol
21:01
i might as well say screw the freenas
21:01
<alkisg>
So you're saying that the same user, if he logs in the LTSP server, everything works, but if he logs in on a client, it doesn't? That doesn't sound right...
21:02
As thin client sessions *are* on the server
21:03
<TheMatrix3000>
well, i can log into the server via ssh
21:03
<alkisg>
That's not what I'm asking though
21:03
<TheMatrix3000>
but when i log in via thin client it freezes
21:03
<alkisg>
I'm asking, "what happens if you normally login on the server with a user". GDM and everything.
21:03
<TheMatrix3000>
it freezes
21:04
but when i log into ssh it doesn't
21:04
<alkisg>
Right. So it's completely unrelated to LTSP
21:04
<TheMatrix3000>
ah ok
21:04
<alkisg>
Try asking in #freenas - you don't even have to mention you're using LTSP at all, it doesn't interfere with anything
21:04
<TheMatrix3000>
oh ok
21:05
<alkisg>
You just have an ubuntu machine trying to connect to a freenas server. Do mention if you're using LDAP though.
21:06
<TheMatrix3000>
k
21:11
<alkisg>
Ah, and a good step forward would be to make it work without LDAP first (e.g. from another, standalone ubuntu installation)
21:11
Because if you can make that work, then it's an LDAP problem
21:11
<TheMatrix3000>
i think its a /home freenas mount issue cause it worked until i mounted home
21:11
<alkisg>
While if you can't, then it's a freenas problem
21:12
<TheMatrix3000>
so i will try and find a solution there, if not tomorrow its getting rid of freenas and using ubuntu
21:12
cause with ubuntu i can just simply mount it
21:12
<alkisg>
And when you login with ssh on the server, you can access /home/username normally?
21:13
Or that hangs too?
21:13
<TheMatrix3000>
yea that works
21:13
but i cant write or edit the /home directories
21:13
and they all have nobody nogroup
21:13
as the permissions instead of each user
21:14
for each folder
21:14
cause /home/bob should have bob
21:14
bob:bob
21:14
but it doesn't
21:14
<alkisg>
Clearly a misconfiguration then. Try first without LDAP.
21:15
<TheMatrix3000>
has teh same issue
21:15
im sure its freenas
21:15
and i am sure no one has done it for a reason
21:15
i can't find anyone online doing what I am trying to do
21:15
they just use the ubuntu nfs
21:15
which is what I will probably do
21:16
<alkisg>
You're saying that noone has used freenas for an NFS server?
21:16
For /home?
21:17
<TheMatrix3000>
i cannot find anything on google mentioning it
21:17
most is samba/active directory related
21:18
<alkisg>
If people at #freenas say that they don't support NFS /home, then sure, get rid of it. If they say they do support it, check your configuration without LDAP first.
21:18
<TheMatrix3000>
they haven't said anything
21:19
and i can get it to work with ldap
21:19
but i have to create a nfs share for each user
21:19
lol
21:19
<alkisg>
Hehe - also try the mailing list etc
21:19
<TheMatrix3000>
f that
21:19
i think ubuntu is easier
21:22
<alkisg>
Btw and just out of curiosity, why would someone use a separate NFS server for LTSP, instead of e.g. putting a hardware or software raid in the LTSP server itself, which would be many times faster? I'm just asking, I don't have experience with large sites...
21:36
<Gnoze5>
fiber optics is fast enough
21:36
:P
21:37
<TheMatrix3000>
well
21:37
our ltsp server itself only has 175gb storage
21:37
its a 15k sas system
21:37
with raid 1
21:37
we don't have the money to buy mroe drives
21:38
and the server is connected gigabit, and so are the nfs servers
21:38
<alkisg>
But still the direct hard disk access is very faster than networked gigabit access, right?
21:39
And you could e.g. take out the disks from the nas server and put them on your ltsp server, without wastng any money?

21:40
<TheMatrix3000_>
sorry internet
21:41
<Gnoze5>
alkisg in big implementations the advantages of external storages are more evident
21:41
<alkisg>
21:41
21:41
<Gnoze5>
redundancy
21:41
centralization
21:41
ease of administration
21:41
<TheMatrix3000_>
no i cant
21:41
<alkisg>
Also, if only the LTSP server access the external server, why not use NBD rw and avoid all the NFS overhead and complexity?
21:41
<TheMatrix3000_>
alkisg, the disks in the ltsp server are SAS drives
21:41
<Gnoze5>
specific features as well
21:42
<TheMatrix3000_>
the disks in the nfs server are SATA
21:42
I don't see how its really complex because look at this
21:42
https://help.ubuntu.com/10.04/serverguide/C/network-file-system.html
21:42
definitely doesn't seem complex
21:42TheMatrix3000 (~TheMatrix@oh-76-1-33-235.dhcp.embarqhsd.net) left irc: Ping timeout: 255 seconds
21:42
<alkisg>
Redundancy and centalization => those are the parts that I don't get, unless of course the LTSP server is only a minor part of the infrastructure that accesses the NFS server
21:42
<TheMatrix3000_>
yes
21:43
<alkisg>
TheMatrix3000_: NFS doesn't support all file types, all types of locking etc
21:43
<TheMatrix3000_>
and we are trying to have windows machines access those same directories
21:43
as smb
21:43
<alkisg>
It is a networked file system that is user-aware, it's bound to be complex - not the configuration part, but the implementation part
21:43
So e.g. I've seen NFS problems numerous times, with my configuration being correct
21:44
<TheMatrix3000_>
well i can restrict the export to specific machines
21:44
basically it goes back to my original problem
21:44
i can't put SATA drives into a SAS system
21:44
the drive simply do not fit
21:44
and we don't have teh $$$ to purchase more drives
21:45
we also have many servers and systems
21:45
were we could benefit from mounts

let me put nfs-kernel-server on the current ltsp server
21:46
and see how well the ubuntu one works
21:47
and just mount everyones current /home to the new ltsp server
21:47
just to test
21:52
fuck
21:52
i lost connectivity and now i can't access it with a new login damnit...
21:52
basically the home directory has fucked me
21:52
lol
21:53
well it works on my other server
21:57
well, i was able to get mounting to work and stuff

crap
22:07
because i messed up the home directory i can't login anymore

got to go to the machine locally and not remotely and remove the mount
22:07
cause my internet dropped
22:07
and i lost my current session

losing the current session is ot good..
22:08
are you locked out?

<alkisg>
Ah you have pam_createhome that fails...
22:11

since i killed the /home/mount on the nfs
22:11
<alkisg>
Or something
22:11
<TheMatrix3000_>
oh, wait
22:12
i might be able to restore it
22:12

For next time, do create a user with home outside of /home :D
22:15

nope, didnt work
22:15
looks like im going to have to visit the office tomorrow

22:27

i am im chugging it
22:27
lol
22:32
hey to fix this unable to get home directory error all i have to to is restart the server right
22:32
and it wont mount the directory
22:35
