05:00
whats wrong in that
05:00
any idea
05:00
my usb and cdrom on thin client not working
05:01
<laga>
i have no idea what's wrong, but you don't need ltspfsd on the server
05:01
nfs-kernel-server is also not needed on a standard setup
05:02
<generic>
then
05:02
what i should need to check
05:02
also i am booting thin client gives me initramfs error
05:02
what this mean
05:03
plz help its urgent
05:04
<laga>
no. nobody can help you if you don't provide the exact error message.
05:08
<generic>
well see wehan i boot thin client it gets ip and load image then kubuntu screen comes and suddenly it becomes blank saying initamfs and a prompt
05:09
error connect : connection refuse
05:09
mount:mounting /rofs on /root/rofs failed invalid argumnet
05:10
target file system doesn't have /sbin/init
05:11
file name :/ltsp/i386/pxelinux.0 error connect : connection refuse
05:11
what this mean
05:14
helo laga?
05:15
<laga>
hum
05:15
if i had to wager a guess, i'd say that it can't connect to the nbd server.
05:16
does that happen on all thin clients?
05:19
<generic>
yes
05:19
nbd why not
05:20
i just do default intsall
05:20
<laga>
alright, so none of your thin clients are booting?

Just Upgraded from 7.10 to 8.04 of Edubuntu. I seem to not have TFTP running on the server. Do I need to install xinetd?
12:49
<laga>
no, openbsd-inetd is what's used.
12:49
ltsp-server should have pulled that in
12:49
<joebaker>
thanks. I'll check into that.
12:50
It is running.
12:50
Checking configuration
12:51
The inetd.conf file lists the port number for tftp as "tftp"
12:52
etc/services says it should be port 69. I'll try modifying that.
12:53
<laga>
um
12:53
why?
12:53
<joebaker>
I have also executed ufw disable just in case the firewall was stopping access.
12:54
Changing tftp to 69 in the inetd.conf config file didn't help.
12:54
I followed instructions here to do the upgrade of LTSP: http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/ltsp-updates.html
12:55
<laga>
what exactly is the problem?
12:56
<joebaker>
Client acquires dhcp, then indicates PXE-E32: TFTP open timeout... TFTP....
12:58
<laga>
interesting..
12:58
maybe restart the ftp server?
12:58
<joebaker>
Then it says PXE-M0F: Exiting Intel PXE ROM.
12:58
Boot Failure: System Halted
12:59
<laga>
err, inetd
12:59
<joebaker>
I tried that.
12:59
Trying again.
13:00
<laga>
maybe there are some hints in /var/log/daemon.log
13:00
<joebaker>
This is not a huge deployment.
13:00
I will check that log.
13:01
Only dhcpd messages there.
13:03
<laga>
then i'm out of ideas :(
13:03
maybe someone else knows more
13:03
<joebaker>
Thanks. I am checking if the tftpd command is actually installed.
13:03
It wasn't
13:03
<laga>
it's in the tftpd-hpa package
13:04
<joebaker>
Oops! Removing ltsp-server-standalone ...
13:04
Removing ltsp-server ...
13:04
Removing tftpd-hpa ...
13:04
<laga>
umm.. yeah. :)
13:04
<joebaker>
Thanks. I' ll put it back
13:04
what does 'hpa' stand for?
13:05
<laga>
Description: HPA's tftp server
13:05
;)
13:05
i think HPA is the guy who wrote pxelinux
13:07
<joebaker>
My ps command shows this:
13:07
/usr/sbin/in.tftpd -s /var/lib/tftpboot
13:09
I'm killing off those processes and running it from the command line to see if I get any logging info to stdout.
13:09
Nothing reported.
13:10
It might be better to migrate to tinydns in the future to integrate dns, dhcp & tftpd all into one package.
13:10
<laga>
dnsmasq can do that, too :)
13:12
<joebaker>
That's the one I meant.
13:14
Even adding -v to the in.tftpd command yeilds nothing from the tftpd's verbose output. I wonder if dhcpd is directing tftp to the right server?
13:15
Is this line still necessary with LDM?
13:15
option root-path "192.168.1.63:/opt/ltsp/i386";
13:16
<laga>
check your dhcpd.conf for the next-server directive then
13:16
not sure, i dont use those parts of LTSP
13:16
<joebaker>
next-server 192.168.1.63;
13:16
This is the IP of the LTSP server.
13:16
<laga>
hum
13:16
try commenting out that part?
13:17
<joebaker>
I found it - maybe.
13:18
This box has two nic cards. They both have the same IP address after the upgrade.
13:20
laga: Thanks for your help. I think this will require me to reboot after I shut down the other NIC from automatically starting. I'll look at the route commands. I thought it was odd that I could not ping the gateway router, but I can get out to the Internet.
13:20
I can ping the router after performing ifdown eth1
13:20
<laga>
sounds like an ugly problem :)

hello I'm tryin to find out about 'fat' clients and how they work
15:29
we wan to run flash intensive site with some movies
15:29
its been suggested that it maybe best to get thin clients that can run firefox locally with all the add-ons
15:31
can someone comment on this please?
15:32
<vagrantc>
!question
15:32
<ltspbot`>
vagrantc: "question" is if you have a question about ltsp, please go ahead and ask it, and people will respond if they can. please also mention the linux distro and release you're using. :)
15:32
<majikins>
um sorry - we still in investigation
15:33
looking to use ubuntu 8.04 with ltsp5 in repositories
15:33
its actually for a school
15:33
the material they will access is lessons in flash and mpeg
15:35
<stgraber>
do they need the standard desktop or only firefox+flash ?
15:36
<majikins>
they will need to use openoffice and access the usual educational programs available in edubuntu
15:36
we looking to put this server side
15:37
but my question is about the 'fat' client running firefox with flash plugin etc
15:37
<stgraber>
how powerful are your clients ? are they thin clients or standard workstations ? (just trying to see if fat clients are an option for you)
15:37
<majikins>
we have not bought any equipment yet - still in investigation stage
15:38
how does this 'fat' client configuraton work?
15:39sepski has quit IRC
15:39
<majikins>
I have done some googling and have found some thin-clients that run firefox locally
15:40
is there a configuration option for the server tot recognise that it can send the compressed flash down to the client to decompress?
15:41
how does t
15:41
f
15:42
how does the firefox icon integrate onto the displayed screen on the terminal?
15:43
hello?

warren: what is the recommended thin clients for that and where can I read up to configure the server for that setup?
15:52
warren: we are looking at hp thin clients
15:52
<warren>
that isn't an easy question, sorry.
15:52
I have no experience using HP thin clients
15:56
<majikins>
um ok - what thin clients do you use that run firefox locally?

<vagrantc>
majikins: there's a proof of concept for running individual applications locally, but there is a lot of work left to do to make it viable.
16:04
majikins: it's easier, though not trivial, to run all applications locally, if your thin-client hardware is good enough. it would basically need to be just as good as a standalone desktop, except with more ram, probably.
16:05
<majikins>
vagrantc : thank you for the information - thats why I was probably not getting much info while search google

Hi, if my ssh keys are wrong can I somehow fix it on the fly on a client by switching to the console, login as root and enter some commands?
17:04
(I mean temporarily, just to log on once or for diagnostic purposes, I know about ltsp-update-sshkeys)
17:05
<johnny>
it would have to be done for every client, but i think it would work

johnny, just for 1 client, I have some problems with virtualbox with NAT networking
17:06
and I'm not sure if it uses 127.0.0.1 to communicate with the host. What commands should I give?
17:09
Symptoms: I try to login, I *don't* see any error messages in ldm (nor in /var/log/ldm.log), but after 2-3 seconds X is restarted and I see ldm again...
17:10
I can logon from the client console using "ssh -l username server" and saying "yes" to the ssh prompt about accepting the key
17:11
It worked OK yesterday, I installed firefox to the chroot and updated the image, and now I can't logon! :(
