Hello
07:32
All
07:33
<alkisg>
Hi
07:33
<coseus>
I have a Ubuntu LTSP server , with dhcp on Windows
07:34
But when i want to boot a client a have this error : getaddrinfo faild: name or service not found
07:35
then : /scrips/init-bottom/ltsp: line 27 :panic:not found
07:36
<alkisg>
At that point, try: cat /proc/cmdline
07:36
What is the output?
07:37
<coseus>
BOOT_IMAGE=/boot/vmlinuz-3.13.0-100-generic root=UUID=f8331da2-c756-43b3-bcd7-3f2bc0e98d27 ro quiet splash vt.handoff=7
07:37
<alkisg>
On the client, not on the server
07:37
<coseus>
aha
07:40
ro initrd=initrd.img-3.13.0-24-generic init=/sbin/init-ltsp quiet splash root=/dev/nbd0 BOOT_IMAGE=vmlinux-3.13.0-24-generic BOOTIF=01-4--61-86-24-57
07:41
<alkisg>
Looks good, it sounds like your dhcp server isn't sending next-server properly for the initramfs ip request
07:41
Do you have an ip now on the client?
07:41
ip a
07:41
==> see if it shows an ip with that command
07:41
<coseus>
Yes
07:42
I have
07:42
<alkisg>
OK, distro/version?
07:42
<coseus>
Ubuntu 14.04
07:43
<alkisg>
Try: ipconfig
07:43
(I'm not sure if it demands "eth0" after ipconfig)
07:43
What is the output?
07:43
(all commands to be ran on the client)
07:43
<coseus>
ipconfig :no device to configure
07:44
<alkisg>
ipconfig eth0
07:47
<coseus>
eth1 harware address ... mtu 1500, dhcp rarp , eth1 guessed broadcast address....
07:47
then the address of eth1
07:47
gateway and domain
07:47
<alkisg>
We care about root server and root path and next-server
07:48
<coseus>
rootserver: 172.16.123.132 roothpath : opt/ltsp/i386
07:48
<alkisg>
Is that your ltsp server IP, or the windows server ip?
07:48
<coseus>
filename :ltsp/i386/pxelinux.0
07:48
is my ltsp server
07:50
<alkisg>
Hmm can you reboot the client, then take a photo of the boot screen with your mobile phone, and upload it somewhere?
07:50
<coseus>
Yes
07:50
<alkisg>
!ipappend
07:50
<ltsp>
ipappend: o temporarily solve DHCP problems in the initramfs, try putting IPAPPEND 3 after the APPEND line in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default. More info: http://www.syslinux.org/wiki/index.php/SYSLINUX#IPAPPEND_flag_val_.5BPXELINUX_only.5D
07:50
<alkisg>
coseus: you can also check if this ^ temporarily fixes the issue
07:51
The pxelinux.cfg/default file will probably have ipappend 2 inside it, check if changing it to ipappend 3 temporarily solves the issue
07:51
<coseus>
ok
07:54
Thanks for support
07:54
It works
07:56
Now i want to see autologin and auto start mozilla in kiosk mode
07:56
I hope it works
07:57
<alkisg>
It was a temporary fix, it will stop working after ltsp-update-kernels.
08:09
<coseus>
Ok
08:15
How can be a permanent fix?

Hi, how edit /var/lib/tftpboot/ltsp/amd54/pxelinux.cfg/defaults for enable usb-ports acces(usb stick, printers)? (use - Thin Client)
10:38
<alkisg>
Guest21210: why do you prefer thin clients instead of ltsp fat clients which work normally with usb ports etc?
10:38
Those are still netbooted and diskless
10:38
!ltsp-pnp
10:38
<ltsp>
ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
10:43
<Guest21210>
thx, will view ltsp-pnp

10:44
<alkisg>
Guest21210: what are your client specifications? Which CPU and how much RAM?
10:44
And how many clients?
10:56
<Guest21210>
try a test server: Socket 755 Intel (R) Core (TM) 2 Quad CPU Q8400 @ 2.66 Ram 8Gb. raid10 500Gb, vgaGF108 [GeForce GT 620], OS ubuntu 14.04 tls (KDE - workspase for clients) .
10:56
<alkisg>
Guest21210: specifications for clients, not for the server
10:56
Your ltsp clients have 8 gb ram?
10:57GodFather has joined IRC (GodFather!~rcc@96-92-43-9-static.hfc.comcastbusiness.net)
10:57
<Guest21210>
no, client pc intel celeron 4 gb ram
10:58
<alkisg>
Those are fine for ltsp fat clients then, you don't need to use them as thin clients
10:58
Try a test server with ltsp-pnp
10:58
They'll perform much better that way
10:59
<Guest21210>
Clients planned 60-70, if get good work server ltsp
10:59
but, head server will bw other
11:00
thx

hi, I've problems with (k)ubuntu 14.04-32 and bond, seems bond is unable to bring up the slave interfaces, works if I do a ifup eth0 ifup eth2 and then ifup bond0
19:53
if I instead do a ifup bond0, it tries until timeout
19:53
"cannot get current wake on lan settings" (that should be unrelated)
20:01
ok, works now that I've dropped the -lts kernel and gone back to 3.13
20:04
<||cw>
markit: I have iface eth# inet manual for both, then i also have the bond manual, and then I have a vmbr0 "bridged" to the bond, this seem complex but reliable
