| 12:08 | <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
| |
| 14:46 | ben_roose has joined IRC (ben_roose!~roose@roose.cs.wichita.edu) | |
| 14:55 | <SmashK> what kinda working mode you mean?
| |
| 14:55 | lucascastro 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> !vnc-edide
| |
| 15:08 | <ltsp> vnc-edide: To share your screen with me, open Epoptes → Help menu → Remote support → Host: srv1-dide.ioa.sch.gr, and click the Connect button
| |
| 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

| 16:06 | <Arai> 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

| 20:09 | kjackal has joined IRC (kjackal!~quassel@athedsl-174053.home.otenet.gr) | |
| 20:09 | <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
| |
| 20:43 | Faith 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 | <vagrantc> lucascastro: it was a typo
| |
| 20:58 | <lucascastro> ok
