hello all, looking for some help on a Pi Net DHCP issue
01:58
i have a Pi2 with Ubuntu 14.04 installed. Current stable version if PiNet. I have a linksys router as my dhcp host. My Pi2, laptop, smart tv and blu ray player all get ip addresses via dhcp no problem. the 6 Pi1 B+ I have will not get an ip address via dhcp. i tried both the SD card image and the files in the Piboot folder. it is exactly the same issue as this https://github.com/PiNet/PiNet/issues/10 excepy my Pi2 is running Ubunt
01:58
as the boot devices
02:00
these pi'si using the pinetSDimage are not taking dhcp. i know dhcp is working correctly or all the other devices in my hose not work.
02:03
i am going to test a full rasbian SD image on one of the B+'s to see if takes dhcp. if it does then something about the pi net boot files is not handling dhcp right. if that also does not work there might be a compatibility issue with a Pi1 B+ model?
02:07
i have been a network admin for 15 years so i know this type of basic networking very well. my wiring is correct and i did verify that the server address on the commandline.txt file is correct its just not getting an ipaddress itself so at that point commandline.txt doesn't really come into play yet correct?
02:49
ok just loaded Rasbian Wheezy on and SD and booted it on the Pi1 B+ and it got a dhcp address.
02:51
putting the pi net boot sd card back in and nothing. guess ill try to reinstall pi net from scratch and try again
02:56
could this be an NFS vs NDB issue? under select network it says NFS is broken in 3.18 so only NDB is available.
03:37
shoot i am actually using 15.10 lxde as the host os for PiNet.
03:45
if i move the same SD card that will not get dhcp in the B+ into the Pi2 it boots and gets dhcp from both the ethernet and the wifi both
03:45
something with the PiNet boot files will not let dhcp work on all 6 of my Pi1 B+ models

<muppis>
alkisg, I think question is for here because my issue is ltsp related. In default Ubuntu MATE it works fine, but in LTSP (by your wiki) I can't get it working due missing /dev/vchiq and I haven't yet figured how I get related module loaded. >)
06:52
<alkisg>
muppis: in Ubuntu Mate, what's the output of: `apt-cache policy omxplayer`?
06:58
Also, the problem is that the module isn't there at all, or that the user is not in the "video" group?
06:58
<muppis>
Module isn't at all.
07:00
http://paste.muppis.net/?e96e940d17c64f4a#gr08pwN1waxFJed7OGpomE1hIoxN+FIiSheePYoIe0U=
07:02
<alkisg>
So it's not in the repositories, ok
07:03
muppis: can you give me access to the rpi client, so that I can check a few things quickly? E.g. do you have epoptes-client installed in it?
07:03
In raspbian, I see /lib/udev/rules.d/10-local-rpi.rules
07:04
It belongs to the libraspberrypi0 package
07:05
Is that installed in the ltsp chroot vs the ubuntu mate chroot?
07:07* alkisg has an rpi2 at work, but no hdmi monitor to test it with...!
07:07
<muppis>
Not even hdmi dvi adapter?
07:08* muppis sets up another rpi2 to ease things.
07:13
<muppis>
Yes, file is there.
07:14
<alkisg>
muppis: can you compare the output of `lsmod` between ltsp/mate?
07:15
I don't see the libraspberrypi0 package in ubuntu, so I wonder how the file got there in the ltsp chroot
07:16
<muppis>
I installed manually it.

<alkisg>
Are you using the 4.2 -raspi2 kernel?
07:18
<muppis>
Yes.
07:20
<alkisg>
Do you have the package libraspberrypi-bin installed?
07:21mikkel has joined IRC (mikkel!~mikkel@mail.dlvs.dk)
07:22
<alkisg>
Btw, does ubuntu-mate have a custom repository? I imagine "no", but you can look at apt sources.list to verify...
07:34
You can also compare the list of packages that have "rasp" or "rpi" in their names, between ltsp/mate, to see if we have something missing
07:37

07:39
Mate has ppa:flexiondotorg/wily-pi which provides libraspberrypi0 and youtube-dl
07:47
<alkisg>
What kernel is mate using? Maybe you should try with the newer 4.3 kernel from xenial: https://launchpad.net/ubuntu/+source/linux-raspi2
07:48
<muppis>
It seems to be 4.1.13
07:49
<alkisg>
Weird, the raspi2 kernel in wily is 4.2
07:50
<muppis>
I haven't updated it lately. Let's see.
08:01
Oh. linux-image -meta package were missing, that's why had old kernel. :D
08:09Phantomas has joined IRC (Phantomas!~ftsamis@ubuntu/member/phantomas)
08:52
<muppis>
Managed it working. :D
08:54
<alkisg>
What was needed?
08:55
<muppis>
libraspberrypi* packages and user to video group.
08:58
<alkisg>
But you already had libraspberrypi0 installed, didn't you?
08:59
<muppis>
I installed it to chroot earlier.
09:02
I'll rebuild the chroot and recheck steps needed.

muppis: so you managed it without changing the kernel?
10:51
muppis: it'd be nice to put the necessary packages in the ppa, along with instructions in the wiki
10:57
Ah, nice ppa! https://launchpad.net/~ubuntu-pi-flavour-makers/+archive/ubuntu/ppa

<alkisg>
Upon installing omxplayer and libraspberrypi0 in an rpi ltsp client, I immediately got /dev/vchiq without rebooting
11:23
<muppis>
I think it just were permission problem after all.
11:24
Is remote apps the key to launch Libreoffice at server from browser running as local?
11:35F-GT has joined IRC (F-GT!~phantom@ppp121-44-155-201.lns20.syd7.internode.on.net)
11:41
<alkisg>
`ltsp-remoteapps soffice` will run libreoffice on the server and it will display it to the rpi screen
11:42
(after you enable it to lts.conf - or you can also use remote apps menu items)
11:44
<muppis>
Should there be a .desktop file for MIME associations?
11:46
Like user can click directly from Chromium downloads to open file.

15:17
<nyusan>
well in have been searching some alternatives. My last and working approaching is use a w7 "server" with wxp RDP clients.
15:18
and right now it is working. (at less worked with one and make try for multilogin with 9 VMs)
15:18
and i have been searching in forums for a linux alternative to this configuration
15:19
kinda xrdp server and rdesktop clients. But not sure how to begin this search
15:19
some time ago you suggested me to use tinycore
15:19
<cyberorg>
what exactly you want to do?
15:20
<nyusan>
ah! there is alkisg... Greetings
15:20
my first intention was to setup an LTSP server
15:21
but the hardware of the cleints was not enough for that
15:21
**clients
15:21
then a suggestion was use tiny core for PXE booting
15:21
my mind could not handle that anymore... was so may trys uncessfully
15:22
then looked for alternatives, and installed wXP on them, tried RDP to a w7 server and it is working pretty well
15:22
<cyberorg>
you want ltsp server to boot client and log in to windows?
15:23
<nyusan>
you mean from a wxp client_
15:23
?
15:23
i would like some like that, log in in a ltsp server from wxp clients
15:24
but i guess that it would be a bad idea, is for that, then i looked for the RDP alternative
15:24
i am begging to you for a suggestion of RDP server in linux
15:24
<cyberorg>
install xrdp?
15:25
<nyusan>
i have been searching for that. I have not tested it yet. Is the perfomance almost the same than RPD?
15:25mikkel has left IRC (mikkel!~mikkel@mail.dlvs.dk, Quit: Leaving)
15:25
<nyusan>
**btw i will test it
15:25
but i really would like to that RPD client would be a linux native...
15:26
It is a "prefeeling" if rdp windows-windows works well, then windows-linux maybe not, had better linux-linux
15:27
<cyberorg>
what do you have for client?
15:28
https://lizards.opensuse.org/2015/12/21/announcing-li-f-e-42-1/ has ltsp and xrdp both ready to use
15:28
<nyusan>
THANKS!
15:28
i will test in
15:28
**test it
15:29
<cyberorg>
for ltsp you need client with minimum 512M ram for passable performance, have lot more if you intend to make heavy use of client
15:30
<nyusan>
in the client i would like some lighter than wXP, as far as i have seen even w95 could have a rdp windows client.
15:30
<||cw>
pretty sure I have several on 256MB that use xfreerdp client to a windows server just fine
15:30
<cyberorg>
nyusan, as alkisg mentioned before booting client with lot less resource is not an issue, but using firefox/office etc on them is a big challange
15:30
<nyusan>
**about LTSP, i do not get actually why is it so exigent with ram-proc
15:31
<||cw>
nyusan: it's not. it's about network performance and your applications and workload.
15:32
if you want web browsing, the images and animations will have to be streamed raw over a 100Mbit network and that will suck
15:32
having a local web browser improves that greatly, but also increases memory requirements

15:34
<||cw>
ltsp itself has very small requirements, it's your applications and use that increases it
15:34
<nyusan_>
as i was telling about, the RDP approaching is much better
15:35
<||cw>
not really
15:35
<nyusan_>
**was
15:35
in my test
15:35
LTSP did not even could boot sucessfully the clients
15:35
only got kernel panic every time
15:35
<cyberorg>
nyusan_, try it out use xrdp and normal ssh with LDM_DIRECTX etc with lightweight WM like xfce
15:35
<||cw>
that's not the same thing...
15:36
<nyusan_>
(i know) but at that way, i got tons of headache with ltsp
15:36
<||cw>
rdp is just a protocol, you still need a OS and a client application, which ltsp can do
15:36
<cyberorg>
you can also install tinycore ltsp package on li-f-e to boot up low end spec clients and try ssh and rdesktop both to see what works best for you
15:36
<nyusan_>
i guess that it is the best and more "justice"
15:37
<||cw>
nyusan_: if your clients don't support PXE and linux isn't supported well on them, that's a different problem than "RDP works better"
15:37
<nyusan_>
for this limited hardware, will be better @use what i have already tested@
15:37
sorry for that, i am not good expressing my self in english
15:37
<||cw>
if the hardware already has an OS, sure, use it
15:38
you can RDP or VNC to a linux server
15:38
<nyusan_>
cyberorg, again thanks a lot, i have more thing for google
15:38
<||cw>
but that's outside of LTSP, though you can also ltsp integrate so you can PXE boot other things and have the same environment
15:39
<nyusan_>
that is what i must...
15:39
Well, then Xrdp is a good "rdp linux server"
15:39
<cyberorg>
nyusan_, follow ltsp link from that link i posted
15:39
<nyusan_>
and i must test it

<cyberorg>
for tinycore https://lizards.opensuse.org/2014/05/31/tiny-core-kiwi-ltsp-thin-client/
15:40
<nyusan_>
the one with open suse, right?
15:40
<||cw>
nyusan_: my primary use case for ltsp is to have old desktop PCs PXE boot and run xfreerdp to connect to windows virtual machines. it works quite well.
15:40
<nyusan_>
you mean windows VM (server)?
15:41
<||cw>
yes
15:41
<nyusan_>
and "xfreerdp" or "rdesktop" a good RPD client?
15:42
btw, any idea about a "very old linux distro wich could be installed on SCSI HDD and with RDP client build in"?
15:42
<||cw>
this way the windows installs are in the server room, and the PCs in the factory have no hard drives, and if one dies due to being in harsh conditions I just replace with with another $20 used system and the station is up in 10 minutes time
15:42
use xfreerdp. rdesktop is old.
15:43
<nyusan_>
thanks a lot for your wisdom :)
15:43
<||cw>
nyusan_: why very old?
15:43
<nyusan_>
for be "handled with those clients"
15:43
those clients are so so old...
15:44
<||cw>
link?
15:44
what are "these clients"
15:45
<nyusan_>
Ppro with 96-128 mb ram 233 mhz proc 1 scsi 2gb hdd
15:45
that old
15:45
<||cw>
that's pretty old...
15:47
<elias_a>
nyusan_: Wouldn't it be possible to use a bit more modern hardware? :O
15:47
<||cw>
you could probably install a base minimal debian and then setup and x session that just launches xfreerdp. that's basically what ltsp does for its rdp mode clients.

but yeah, off-leave P4's under 2Ghz are like $10
15:47
off-lease
15:48
you'll spend more time in labor on the ppro's than it's worth
15:48
<alkisg>
There's also raspberry pi zero with $5, that has 512 RAM etc
15:49

ah now i remember, a pi zero actually costs more like $40 unless you happen to already have a USB hub or unified KB/mouse, and the HDMI DVI adapter, or an HDMI display, and power brick, and suitable case...
16:05
<nyusan>
i would like to know where i could buy those pis here... it is so...
16:05
hard to find here.
16:05
<||cw>
still a reasonably cheap system
16:05
<nyusan>
i bough those ppro with 300$s
16:05
<elias_a>
nyusan: Where do you live?
16:05
<||cw>
P4 desktops are still cheaper, especially since you can sue PS2 mouse/KB and VGA displays
16:05
<nyusan>
wich is kinda 40$us
16:06
<alkisg>
||cw: true, but it might also be possible to fit it inside your hdmi monitor and power it from its usb port - that would cost less than $5
16:06
<nyusan>
i live in bolivia
16:06
the sad history and why i still with those ppro
16:06
is that i have already bought them
16:06
<elias_a>
Ok.
16:06
<nyusan>
then i must make them work
16:06
<alkisg>
You *bought* ppro?!
16:07
<nyusan>
yes :(
16:07
<alkisg>
We throw away p3's here, which are much faster than your ppro
16:07
<nyusan>
i know it :(
16:07
<alkisg>
And we're in Greece, with the economy crisis etc...
16:07
<nyusan>
bolivia is worse i guess...
16:07
maybe not so %^$ with economy... but in "culture"
16:07
<elias_a>
alkisg: Perhaps you should tell this story to your colleagues. :P
16:08
<nyusan>
>P
16:08
well, i must say goodbye for now
16:08
<elias_a>
Come back soon!
16:08
<nyusan>
BTW, pls do not ban me... i go my laptop banned the last time
16:08
<alkisg>
Nah they'll tell me that they have some i386 in their closets, and ask me to make them work with ltsp!
16:08
nyusan: noone in #ltsp bans persons
16:08
Look elsewhere for the cause
16:08

@xdrazen" got banned
16:09
i will

did he have trouble with multiple reconnects?
16:09
<nyusan>
yes i got
16:09
<alkisg>
I think I banned one that connected/reconnected 100 times per minute, but I think that was not xdrazen
16:10
Maybe freenode banned you, can xdrazen join other channels like e.g. #ubuntu?

16:14
<alkisg>
w2000 will work, yes
16:14
you can try that
16:16
<nyusan_>
a linux distro in that time?
16:16
<alkisg>
No, to install windows 2000
16:17
Its rdp client is better than the linux rdp client
16:17
And you can install windows server instead of linux server as well
16:18
Since your specs are not covered by linux, just use windows instead
16:19
Or windows 95 if you want to make it work with 16 MB RAM clients as well
16:19
RDP will still work there
16:21
<elias_a>
This channel is suddenly full of foul language. :O
