markit: you can change it in udev with 70-udev-net-rules (dont quote me on the filename)
02:15
Does anyone know if you can use dhcp to specify the right IP address and subnet to allow for internet access on the fat client, and still ltsp, without using DNSmasq or NAT?
02:28
<jammcq>
bennabiy: you might just need to turn on forwarding on the ltsp server
02:29
well... it really depends on your network topology

02:48
<bennabiy>
hmm. My network topology is a 2 nic setup with lab on one subnet, and lan / internet on another
02:48
router issuing DHCP for main subnet, lab server issuing dhcp for lab
02:49
<jammcq>
sot he LTSP server is sitting between the thin clients and the rest of the network?
02:50
<bennabiy>
yes
02:50
but I was to run one fat client
02:51
and not really wanting to set up NAT for anyone to just plug into the network through the lab
02:51
if the fat client is issued a subnet mask of 255.255.0.0 wouldn't it work for accessing both .0.* and .1.* networks?
02:51
<jammcq>
well... you need to turn on ip_forwarding on the server.
02:52
<bennabiy>
oh yeah....
02:52* bennabiy smacks head
02:52
<jammcq>
and then, either setup NAT on the server, add a static route to your router, pointing back at the ltsp server, so that responses can get back to the thin clients
02:53
that is, either NAT or a static route
02:53
<bennabiy>
I guess I might as well just do NAT
02:53
<jammcq>
nat is easy
02:53
<bennabiy>
yes
02:54
If I have a dhcpd.conf which has settings for all clients, and then it has a host directive, will settings in that override the globals?)
02:54
for that host?
03:01
<jammcq>
umm, I think so
03:01
it's been so long since i've even looked at a dhcpd.conf file

19:14* bennabiy marvels at how quiet it is today...
19:25
<bennabiy>
Why do I not have sudo access through my fat client, but I do through thin and server?
19:27
<alkisg>
bennabiy: because the passwd hash isn't copied by ldm to the client
19:27
So since you don't have a local password, you can't authenticate yourself...
19:27
Some people here think that's good for security...
19:27
(not storing the passwd hash locally)
19:29
If you want to be able to authenticate for sudo without giving a password, put RC_FILE01=echo "%sudo ALL=NOPASSWD: ALL >> /etc/sudoers or something...
19:31
<bennabiy>
I want to have to give a password, but my password is not working
19:32
Is there a way to allow for me to have a local user / password which will work?
19:32
Also, I am getting the reverse display bug as my thin clients
19:33
this time, I want it to use the laptop screen, and it is putting the login off to the left
19:34* bennabiy is not too impressed by fat clients so far...
19:34
<bennabiy>
;)
19:40
<alkisg>
No you can't have a local password without hacking ldm
19:40
The display issues are the same for thins and fat clients
19:40
To be impressed, just run a full screen flash
19:41
Or any 3d app
19:41
<bennabiy>
but why does my password work on a thin, and not fat?
19:41
<alkisg>
You can't have a full screen flash player or 3d apps with thins...
19:41
Because on thins you _are_ on the server
19:41
<bennabiy>
meh
19:41
<alkisg>
Your password doesn't work with thins + localapps though...
19:41
Only on the server
19:42
<bennabiy>
so how is one supposed to do anything administrative on a client?
19:42
<alkisg>
Like what?
19:42
Install programs? To be lost on reboot?
19:42
<bennabiy>
like commandline things
19:42
<alkisg>
Like?
19:42
Troubleshooting is the same on thins and fats
19:42
!screen_02
19:42
<ltsp`>
screen_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
19:43
<alkisg>
...for example...
19:43
<bennabiy>
Administering server scripts
19:43
<alkisg>
To be lost on reboot?
19:43
<bennabiy>
SERVER, not local
19:43
<alkisg>
If you ssh to the server, then your password works
19:43
<bennabiy>
ahh
19:43
hmm
19:44
one minute
19:44
<alkisg>
Having an option for LDM to store the passwd hash would be nice, but it's not _essential_
19:47
<bennabiy>
yes
19:48
how fast is it to run things like a VM locally, when the files are on the server?
19:48
:wq
19:51
<alkisg>
bennabiy: fat clients are like local installations, except for the password thing
19:51
The network disk speed is comparable to a local disk speed
19:52
<bennabiy>
ok
19:52
Any thoughts on the display issue?
19:53
For some reason, when I try to use an external monitor on the fat client, the display starts resetting over and over... when I use only the screen, it is login screen to the left
19:54
Is there any way to seed a fat client install from an ISO?
20:08
<alkisg>
About the display, either put video:lvds-1=off or something in the command line, or put an XRANDR...=off command in lts.conf
20:08
Both are mentioned in the irc logs...
20:19alkisg has left IRC (alkisg!~alkisg@ubuntu/member/alkisg, Quit: Leaving.)

stgraber: Do you know why my fat client would give me the error "Transport end points not connected" when trying to access the home directory?
20:50
<stgraber>
bennabiy: I'm quite a bit more than a MOTU :)
20:50
but yeah, being a coredev and archive-admin, I'm indirectly part of MOTU too
20:50
bennabiy: no idea for your ssh error... is that using nfs or just standard sshfs?
20:50
<bennabiy>
nbd sshfs
20:51
not nfs
20:51
stgraber: Would you be one I could talk to about getting a simple ldm package into repo?

stgraber: did you post the photos you took at BTS somewhere?
21:24
<stgraber>
ragnarw: not yet, had a pretty busy week, got them all loaded on my laptop at least, just need to do some triaging and publish at photos.stgraber.org
21:25
<ragnarw>
