Well, I tried with just the district dns and it worked for a few chrome searches on google, but then reappeared. Then I set it to google's, 8.8.8.8 server and made some tests and it hasn't failed, yet, but will have to wait for Monday's stress-tests!

<Guest7409>
Hi all, Now I have one trouble about LTSP. Can I ask about that?
05:23
The prob. is that Surface Go would not boot up with LTSP.
05:24
<vagrantc>
ask away, wait a while for a response
05:25
no idea what surface go is...
05:25
<Guest7409>
The half of booting, the messages as follow appear, "ipconfig: no devices to configure .... no search or nameservers found in /run/net-.conf /run/net-*.conf /run/net6-*.conf connect: Network is unreachable NFS over TCP not available"
05:26
Oh, thanks for reply.
05:29
Perhaps, this prob. is related to UEFI. Now PCs which have legacy bios can boot up and be used.
05:31
<vagrantc>
old ltsp didn't have support for EFI, but recent versions of LTSP do
05:31
but that could also just be a misconfigured DHCP server...
05:33
also if you somehow got a kernel version mismatch between what was running on the system and what was booted over the network ... but that seems odd that it would get the wrong initrd+kernel
05:33
<Guest7409>
Yes, I installed and used recent version.
05:33
<vagrantc>
i'd expect problems later
05:33
Guest7409: ltsp 19.x?
05:34
<Guest7409>
Yes.
05:36
Yesterday, I installed ubuntu desktop 18.04 and installed ltsp19 on that machine.
05:37
I have not mixed old and new
05:45
<vagrantc>
when you say "The half of booting" ... do you mean it sometimes works fine and sometimes fails with that error?
05:48
<Guest7409>
Sorry for misleading. Surface Go always stops and ubuntu never start.
05:48
I mean,
05:50
I can confirm the success to download NBD files, can see the screen to select image which color of background is blue, and
05:51
can see start boot sequence. But it stops with the message "ipconfig: no device to configure.
05:51
"
05:52
I said explicitly, That message appears repeatedly and system seems to try again and again and ...

Oh! I donot do that! Thanks and I will read your reply! Thanks.
06:41
<alkisg>
I.e. the surface ethernet driver is probably missing from the initramfs
06:42
<ken2>
I read. So i will try to make live usb and get output from now.
06:42
<alkisg>
Do you have a shell in the initramfs?
06:42
If so, run: ip a
06:42
If you don't see an ethernet card name, that's the issue

really sorry. my network is unstable.
07:29
<alkisg>
ken3, if surface doesn't have linux ethernet drivers, then it can't be used as an ltsp client
07:29
<ken3>
Thanks. Now I wrote the results on github. As the results, it seems not to recognize ehternet. I use microsoft usb-typec ethernet/usb adapter
07:30
<alkisg>
Do you see anything if you type `ip a`?
07:30
lspci might not be suitable if your adapter is usb
07:30
<ken3>
Oh, So i try to ip a. pls wait.

Nice, that means that you only need to put the modules in the initramfs, and it'll wor
07:47
*work
07:47
Which module creates enx606d3c3d93ec ?
07:47
<ken4>
Sorry, I cannot figure out.
07:48
<vagrantc>
usb ethernet adapters typically need several modules to work
07:49
<alkisg>
vagrantc: his lsmod is at: https://github.com/ltsp/community/issues/82#issuecomment-573290833
07:49
ken4, one way to find out is:
07:49
You boot your pc without the adapter
07:49
Then you run `lsmod`, and keep it in a file
07:49
<vagrantc>
lsusb --tree can be helpful
07:49
<alkisg>
Then you plug in the adapter, run lsmod again, and compare
07:50
The difference will be the necessary modules
07:50
<vagrantc>
but alkisg's suggestion will get all the needed modules :)
07:50
<ken4>
Ok! I tr ity
07:50
<alkisg>
When you find the modules, you then need to put them in this file on the server: /etc/initramfs-tools/modules
07:51
Then you run `sudo update-initramfs -u; sudo ltsp initrd` on the server, and reboot the client
07:51
<ken4>
Ok! I got it
07:51
<alkisg>
ken4, if you can't find the modules, you can also put *all* of them :D - the ones that are shown in your comment
07:52
<ken4>
before booting, I did lsusb --tree so put res here
07:53
ubuntu@ubuntu:~$ lsusb --tree/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/2p, 5000M |__ Port 1: Dev 3, If 0, Class=Communications, Driver=cdc_ether, 5000M |__ Port 1: Dev 3, If 1, Class=CDC Data, Driver=cdc_ether, 5000M/: Bus 01.Port 1: Dev 1, Class=root_hub,

cdc_ether ... curious.
07:55
that's often used by single-board-computers to emulate an ethernet device via usb-otg
07:55
<ken4>
Ok, thans a lot.
07:55
<alkisg>
It's worth a try, to put it on the server /etc/initramfs-tools/modules ...

=D Once I reboot

Hrm I don't see that module in his lsmod output

Maybe he had used wireless when running lsmod

<ken5>
Thanks about the problem on surface go. Now I cannot solve...
08:36
Perhaps the module name of usb type-c ethernet/usb adaptor which I use is 'cdc_ether'.
08:37
I added it to '/etc/initramfs-tools/modules' and ltsp initrd, but same problem occur.
08:38
Now I try to ltsp image / and ltsp ipxe, nfs and initrd(I cannot judge whether 'ltsp image /' is needed or not)
08:43
<alkisg>
Did you run `update-initramfs -u` before?
08:45
<ken5>
Yes, I did that command. Do'nt I need `ltsp image /'?
09:02
<alkisg>
You need both of them, in order
09:11
<ken5>
Oh, just I did only update-initramfs -u and ltsp initrd... Now I am doing ltsp image / !

<alkisg>
Sory, I misread, you don't need ltsp image, only update-initramfs and ltsp initrd, like I wrote before
09:37
<ken5>
YES! Thanks! Ubuntu works on surface go with usb type-c ethernet/usb adapter.
09:40
Really thanks! I did as follow. 1) I added module list by getting lsmod to /etc/initramfs-tool/modules, and added 'cdc_ether' to that file. (because the list did not have the module).
09:40
2) update-initramfs -u
09:42
3) ltsp image /; ltsp ipxe; ltsp nfs; ltsp initrd; (as alkisg saying, perhaps only ltsp initrd is needed, but I didnot comfirmed)
09:42
I used microsoft usb type-c ethernet/usb adapter.
09:42
The infomation is over. I wanna say thank for all again.
