<SmashK>
tried yesterday to see the shares of my LTSP-Server (inside vbox) from Windows' Explorer by using \\192.168.67.1 but he showed me the windows-own shares of the host
12:09
why is it mirroring the host shares to the LTSP-IP?
13:52
real PC dont want to boot with PXE from LTSP-Server
13:52
it gets no IP from DHCP
13:53
while thin-Client in other vbox-machine works
13:54
can see DHCP-pings from hardware-PC in Etherape on LTSP-Server, going from routers-IP 192.168.178.1 via 255.255.255.255 to 0.0.0.0
14:37
<||cw>
SmashK: what networking mode are you using for VMs in vbox? there's at least one that prevents that a lot of host to guest things from working
14:38
it's really more of a vbox issue than anything else tho
14:46ben_roose has joined IRC (ben_roose!~roose@roose.cs.wichita.edu)
14:55
<SmashK>
what kinda working mode you mean?
14:55lucascastro has left IRC (lucascastro!~lucas@201.182.221.14, Remote host closed the connection)
15:02
<SmashK>
bridge from real-hardware-NIC to emulated INTEL Pro 1000, thats you mean?
15:03
<alkisg>
SmashK: ltsp and ubuntu don't enable samba shares by default, so it's possible that you're seeing the virtalbox shared folders, if you enabled that
15:04
In general, ltsp is not related at all to samba, it doesn't use it etc
15:06
<SmashK>
maybe samaba is enabled by default in the latest Debian 9.3 release
15:06
<alkisg>
Are you seeing the ltsp server shares?
15:06
Or the host shares?
15:06
<SmashK>
which way when not by \\ip in Windows explorer?
15:07
<alkisg>
You can just run systemctl and see if samba is running or not
15:07
<SmashK>
I saw host shares by \\192.168.67.1
15:08
<alkisg>

15:09
<alkisg>
I think it'll be quicker if I see directly... than trying to describe it...
15:09
<SmashK>
can't see samba in this wall of text
15:13
<alkisg>
192.168.67.1 is not an ltsp ip
15:13
Your ltsp server ip is 192.168.178.20
15:14
The ltsp server can't even ping 192.168.67.1
15:14
<SmashK>
let me see in Windows
15:14
<alkisg>
And it doesn't have samba installed at all
15:14
samba => Installiert: (keine)
15:14
<SmashK>
cant connect via \\192.168.178.20
15:14
quit confused
15:15
<alkisg>
Yes, they're not in the same network
15:15
<SmashK>
*quite
15:15
<alkisg>
Your router is 192.168.178.1?
15:15
<SmashK>
ping from windows-host to .20 is ok
15:16
<alkisg>
What is the ip of the windows host?
15:16
<SmashK>
.206
15:18
<alkisg>
You do have shared folders there in windows
15:18
<SmashK>
alot
15:18
<alkisg>
I don't see anything having this ip though: 192.168.67.1
15:18
Why do you think that some pc has that ip?
15:19
<SmashK>
am sure that IP was shown yesterday
15:19
I did \\.... and it showed me the host shares
15:19
<alkisg>
And if you do it now, does it show them?
15:20
<SmashK>
do I have any shares on that Server right now?
15:20
<alkisg>
In the ltsp server? No
15:20
You don't even have samba installed. Not even the client.
15:20
<SmashK>
yes, \\192.168.67.1 gives me the windows-shares o.O
15:20
<alkisg>
From the windows server, can you ping 192.168.67.1?
15:21
<SmashK>
TTL=128
15:22
<alkisg>
I cannot ping that from the ltsp server
15:22
Even when I add an IP inside that subnet
15:22
<SmashK>
host name of .67.1 is my hosts name, huh?
15:22
<alkisg>
It's not related to ltsp at all
15:22
I don't know what you did in virtualbox
15:22
Maybe you configured a tap interface in windows
15:23
I cannot see that from inside the VM
15:23
But in any case it's not related to ltsp at all
15:23
And it's not something that windows or virtualbox does; you manually added that IP somewhere
15:24
<SmashK>
.67.x isnt in my routers settings
15:24
<alkisg>
I don't know where you added that. Check in windows, check from other PCs...
15:25
What I do know is that it's not related at all to your ltsp setup
15:25
<SmashK>
rgr, thanx alot
15:25
<alkisg>
np
15:25
<SmashK>
still on the server?
15:25
<alkisg>
Yes, click on disconnect to disconnect me
15:28
<SmashK>
.67.1 is the virtualBox Host-Only Network
15:29
which is not activated as NIC for the LTSP
15:30
<alkisg>
It's activated for your windows though
15:30
So it's like 127.0.0.1
15:30
Btw, this isn't the default ip for the virtualbox host network
15:30
You manually put that...
15:32
<SmashK>
yes, thats possible

Greetings!
16:09
Is there an command from server to send broadcast "reboot" message for thick clients?
16:13
<quinox1>
thick ? thin / fat :)
16:13
<Arai>
fat ones
16:29
<SmashK>
think u can do this with Epoptes
16:37
<Arai>
Hmm, maybe is exists any easier way? Like "echo -en "0\0\0\0reboot\0" | nc 192.168.1.255 514" for wtware clients.
16:42
<SmashK>
http://ltsp-discuss.narkive.com/Guirg2K5/i-need-to-remote-reboot-a-ltsp-5-client
16:42
maybe this way?
17:01
<Arai>
thanks, i'll try
17:13
<alkisg>
!epoptes
17:13
<ltsp>
epoptes: Epoptes is a computer lab administration and monitoring tool. It works on Ubuntu and Debian based labs with LTSP or non-LTSP servers, thin and fat clients, standalone workstations, NX clients etc. More info: http://www.epoptes.org
17:14
<alkisg>
It's very light and much more flexible than just a remote reboot command
17:14
People usually don't want to have an open port than can reboot clients... :)
17:16
But if you do want to have a reboot port, that's just an RCFILE_01="nc -l ..." command away

<lucascastro>
brought at aliexpress. the arrive estimate in 14-30 days.
20:13
<alkisg>
lucascastro: cool
20:13
bennabiy had reported that he was unable to netboot it
20:13
I think because of uefi
20:14
If you fail too, you can easily netboot it with a local grub or kernel
20:14
lucascastro: which one did you buy?
20:15
<vagrantc>
i recently have gotten a bit more experience with network booting EFI systems
20:18
<alkisg>
It'd be nice to add uefi support upstream in ltsp...
20:18
vagrantc: did you manage to boot with proxydhcp mode? That was the show-stopper for me...
20:19
But I heard that later on, dnsmasq did support it
20:19
<vagrantc>
alkisg: yes, using proxydhcp ... though it was an arm64 (u?)efi implementation ...
20:19
<lucascastro>
oops.
20:19
<vagrantc>
i get the impression each EFI implementation will have it's own idiosyncracies
20:20
<lucascastro>
https://www.aliexpress.com/snapshot/0.html?orderId=90150237732239&productId=32838616866
20:21
I brought this one.
20:26
what client are you using? vagrantc, alkisg ?
20:28* vagrantc hasn't had real-world clients for year
20:28
<vagrantc>
s
20:29
which is why i haven't been as active in ltsp development lately
20:31
<lucascastro>
I see
20:31
<alkisg>
lucascastro: i'm using regular i3's normallyh
20:34
<lucascastro>
I live in Brazil. The ideia of thin client and ltsp is reduce some costs in electricity and computer acquisition. So regular computer is too expensive.
20:36
<alkisg>
We don't recommend thin clients anymore
20:36
Only fat clients
20:37
There are i3's or celerons etc in small forms too, e.g. intel nuc
20:37
and atoms are a bit ok, sure
20:40
<lucascastro>
intel nuc over here is a little expensive.
20:41
2k+ BRL
20:42
<alkisg>
We're getting desktop but diskless i3's for just a bit above 200 euros here
20:42
They score 6000+ in cpubenchmark, while atoms score 2000-
20:42
So that double price will get us 3 more life time for each pc
20:43Faith has left IRC (Faith!~Paty_@unaffiliated/faith, Quit: Leaving)
20:43
<alkisg>
The electricity is usually analogous to the performance...
20:43
And if you try to save in client cpu power, you'll spend it on the server AND the network, which isn't better
20:44
If your users can work with atoms, those cheap-clients should be fine then
20:45
Atoms feel slow to me though, I don't recommend them to those that can afford normal CPUs
20:46
<lucascastro>
fine. Where I'm planning to implement doesn't demand too much resource, I brought just one for testing.
20:46
I'm guessing will be ok.
20:48
<vagrantc>
people frequently underestimate what "just browsing the web" means these days
20:48
<lucascastro>
But if I implement a client that will not use 50% of cpu capacity, isn't good too.
20:49
vagrantc: I understand that.
20:49
web browsing but processed at the client.
20:49
<alkisg>
Atoms are usually good for browsing the web with a couple of tabs open. If you open a few more programs or tabs, you feel the lack of performance...
20:50
So don't worry about not using all the client cpu :)
20:50
<lucascastro>
:D
20:51
<alkisg>
lucascastro: how much is a normal salary in brazil?
20:51
E.g. a teacher...
20:51
<||cw>
modern PCs that aren't using CPU also aren't use as much power, so that's a good thing.
20:51
<lucascastro>
954,00
20:52
<alkisg>
Eh, so an intel nuc is two salaries? Yeah that's lame...
20:53
<||cw>
there's a wide range of nuc prices, and power
20:54
<vagrantc>
yeah, the power consumption on modern CPUs tends to be lower than older generation stuff
20:54
<alkisg>
Google says 2000 Brazil reais =503 euros... so.... yeah that's close to a good nuc here
20:55
<lucascastro>
I understand the problem in using older generation.
20:56
<vagrantc>
/7/7
20:56
oops
20:56
<||cw>
you can get late core2 for around $50, and early i3/5/7 for under $100, with 4GB ram, on ebay.
20:57
<lucascastro>
what's means /7/7 ?
20:57

lucascastro: it was a typo
20:58
