hi, i'm using fat clients and have a script which uses udisks to mount the local hdd
11:09

11:09
when i login after boot and do the same sshfs it works
11:10

blueonyx, could it be a race problem?

Could it try to mount the ssh filesystem before network is up, for example?

<fossala>
I have installed ltsp 10 times now and it has always worked but on my latest install it cannot find my tftp server. Where should I start looking (btw I am using debian squeeze).
19:20gvy has left IRC (gvy!~mike@altlinux/developer/mike, Client Quit)
19:21
<Hyperbyte>
fossala, start by asking specific questions.
19:21
<fossala>
OK.
19:22
I cannot boot into my ltsp server. I get a DHCP connection but it cannot gets stuck on finding either my tftp server or the files. My tftp server is running. What files should I be looking at?
19:24
<Hyperbyte>
What's TFTP_DIRECTORY set to in /etc/default/tftpd-hpa?
19:25komunista has left IRC (komunista!~slavko@adsl-195-168-242-217.dynamic.nextra.sk, Quit: Leaving.)
19:26
<fossala>
TFTP_DIRECTORY="/srv/tftp"
19:27
<Hyperbyte>
Where's your lts.conf located? /var/lib/tftpboot/ltsp/i386/lts.conf ?
19:29
<fossala>
normally in /opt/ltsp/i386/etc/lts.conf but there isn't one.
19:29
<Hyperbyte>
/var/lib/tftpboot/ltsp/i386/lts.conf ?
19:30
Or does Debian put it in /srv/tftp/ltsp/i386/lts.conf ?
19:30
<fossala>
I have no files in them places.
19:30
<Hyperbyte>
Okay
19:31
<fossala>
I thought lts.conf was in the chroot normally?
19:31
<Hyperbyte>
Well
19:31
I know -zip- about the Debian implementation of LTSP and where stuff is on Debian
19:31
I figured it'd be similar to Ubuntu, but apparently for lts.conf it isn't
19:32
Either that, or it is and you have messed something up. ;-)
19:32
What's in /srv/tftp ?
19:32
<alkisg>
fossala, Hyperbyte, debian uses nfs, so it has no need for lts.conf in the tftp dir
19:32
<fossala>
lts.conf in ubuntu is outside of the chroot to make things easier (not having to rebuild the image to update your lts.conf.
19:32
<alkisg>
That's why it's still in /opt/ltsp/i386/etc/lts.conf in debian
19:32
<Hyperbyte>
alkisg, ah.
19:32
<alkisg>
fossala: did you run ltsp-update-kernels?
19:33
<fossala>
Think so let me check
19:33
No but I have no, shall I try and boot the thin client again?
19:33
now**
19:35
I tried to boot and it still doesn't
19:36
Is my tftp pointing to the right place? (/srv/tftp)
19:43
<alkisg>
!tftp
19:43
<ltsp`>
alkisg: tftp: Here's a page to help you troubleshoot TFTP problems in Ubuntu: https://help.ubuntu.com/community/UbuntuLTSP/Troubleshooting/TFTP
19:44
<alkisg>
fossala: have a look there, even if it's for Ubuntu, it should give you enough hints to troubleshoot your problem ^
19:44
If not, we can start writing a debian page ;)
19:45
<fossala>
Thanks, I will look.
19:46
<alkisg>
/srv/tftp is the correct dir, yes
19:46
It's the new place for tftp, although Ubuntu stayed with the old location, dunno for how long
19:55
<fossala>
I have tried everything there except the last one but don't have any media around to try it.
19:55
<alkisg>
fossala: so you can get pxelinux.0 with tftp from another computer?
19:57
<fossala>
tftp 192.168.1.88 -v -m binary -c get /ltsp/i386/pxelinux.0
19:57
mode set to octet
19:57

19:58
That was from the server.
19:58
I don't have a spare pc atm (my son has one but he is asleep.
19:58
<alkisg>
OK, if you don't have a firewall that should be ok
19:58
<fossala>
I don't have a firewall.
19:58
<alkisg>
So let's look at your dhcp
19:59
<fossala>
It is a copy and paste from a working ltsp server (hard drive failure) in the same enviroment.
20:00spectra has left IRC (spectra!~spectra@debian/developer/spectra, Ping timeout: 272 seconds)
20:01
<alkisg>
fossala: paste your dhcpd.conf, your /etc/default/tftpd-hpa, and mention if you have another dhcp server in your network (e.g. a router)
20:01
<fossala>
http://pastebin.com/5BzakqZr
20:01
I have my dhcp dissabled on my router.
20:02
http://pastebin.com/34eGtELA
20:02
first is dhcp, second is tftpd-hpa
20:02
<alkisg>
TFTP_OPTIONS="--secure --verbose"
20:02
service tftpd-hpa restart
20:03
Boot client, check syslog
20:04spectra has joined IRC (spectra!~spectra@debian/developer/spectra)
20:06
<fossala>
All that was in syslog was dhcp logs, no tftp.

Mar 3 20:04:09 Dolphin dhcpd: DHCPACK on 192.168.1.20 to 00:80:64:73:46:7f via eth0
20:07
<alkisg>
You put --verbose in /etc/default/tftpd-hpa, restarted the tftpd service, and didn't get any logs at all?
20:07
*log entries from tftp at all?
20:08
<fossala>
I did put --verbose in ../../tftpd-hpa and restarted the service.
20:09
<alkisg>
And your server is at 192.168.1.1 ?
20:09
<fossala>
My server is 192.168.1.88
20:10
I have a mail server an 192.168.1.89 and ltsp clients get between 192.168.1.20-30
20:10
<alkisg>
And at 192.168.1.1 there's your router?
20:11
<fossala>
Yeah, but that has it's dhcp server dissabled.
20:11
<alkisg>
I'm wondering if somehow the client thinks that there's the tftp server, and doesn't ask your server at .88 at all
20:11
fossala: try again that "tftp get pxelinux.0" line
20:11
And check syslog
20:11
Do you see a tftp log entry?
20:12
<fossala>
sorry what do you mean try again "tftp get pxelinux.0" line?
20:12
<alkisg>
(09:57:54 μμ) fossala: tftp 192.168.1.88 -v -m binary -c get /ltsp/i386/pxelinux.0

20:13
Received 26816 bytes in 0.0 seconds [10753330 bit/s]
20:13
<alkisg>
Then tail /var/log/syslog, and see if that "--verbose" actually works, and you see log entries that a file was requested
20:13
<fossala>
yeah it got the request.
20:13
RRQ from 192.168.1.88 filename /ltsp/i386/pxelinux.0
20:14
<alkisg>
I'm not using dhcpd so I don't know its syntax, is it possible that with "    option routers 192.168.1.1;" the client think that the tftp server is there?
20:14
<fossala>
It is bizzare, I had it working in exactly the same enviroment with the same config file on the same os.
20:14
<alkisg>
Can you temporarily comment it out and restart dhcpd?
20:18
<fossala>
Thanks mate all sorted.
