<clueo8>
I setup ltsp server with ubuntu 14.04; having an issue trying to sudo within a fat client; is this possible? I have made my user part of the sudo group on server.

Hi
07:06

<alkisg>
IU: in general, you can't redirect ports from the client to the server
07:33
We have a special software called ltspfs that allows you to do that for file systems
07:33
So the classic way to access other usb things (other than file systems) on the client, is to run ltsp "local apps"
07:34
If you want to redirect the port, you would look at other software, not related to ltsp, e.g. usb over ip
07:34
You can still use those with ltsp, but we can't help you, we're not using that ourselves
07:36
<IU>
tanks alkisg but I don't understend if I can use flash memory on thin client why I can't use arduino ?
07:36
what's difference ?
07:36
<alkisg>
What is connected to the arduino usb port?
07:37
<IU>
sorry ?
07:37
<alkisg>
You want to redirect the usb port, right?
07:37
<IU>
I wont to use arduino connected to thin client
07:38
<alkisg>
Do you know the "mount" command?
07:38
That mounts file systems?
07:38
<IU>
yes
07:38
<alkisg>
Can you "mount" an arduino?
07:38
Can you "mount" a camera or a usb headset?
07:38
No
07:38
<IU>
I think no :)
07:38
<alkisg>
That's why it doesn't work
07:38
What we do in ltsp is that we mount the usb stick on the client,
07:38
and then use something like nfs to export it to the server
07:39
That works only on file systems that can be mounted
07:39
We don't handle the usb protocol at all
07:39
We just handle a directory
07:39
<IU>
only solution is use fat client ?
07:39
<alkisg>
fat client or localapps or usb2ip
07:39
<IU>
and run local apps ?
07:40
can I run usb2ip on thin client ?
07:40
<alkisg>
Yes, but I've never used usb2ip
07:40
I just googled about it some years ago
07:41
<IU>
how you think witch metod is better for use on old thin clients with 700 mhz chips ?
07:42
can I use this clients like fat clients ?
07:59
<alkisg>
IU: how much ram do those clients have?
08:04
http://forum.arduino.cc/index.php?topic=6187.0 ==> here it says that the arduino ide needs more than 1 GB RAM for itself, so I don't think you can run it locally on old clients
08:07
<IU>
tanks for help I will try usb2ip run local on thin client for send usb data to server I hope this help
08:07
thank you anyway for help
08:08
<alkisg>
You're welcome. It might also be possible to plug all the arduinos in usb ports or hubs on the server, and allow the clients to see them, but that also doesn't work out of the box, it will need access management
08:08
So yeah try usb2ip first

alksig I have a problem as I remember when I connect arduino on thin client I can see this arduino on server but not on client, now servers can't see arduino and lsusb show me only ports on server. I forgot something or it must work like that ?

anybody ?

<alkisg>
!localxterm
14:48
<ltsp>
localxterm: Any applications that you launch on a thin client actually runs on the server, not on the client itself. If you want to open a program on the client locally, you can type 'ltsp-localapps <program>' in a run dialog or in a terminal. For example, 'ltsp-localapps xterm' to open a terminal running on the client.
14:48
<alkisg>
IU: ^
14:49
You need localapps

I use localapps but when I connect arduino on thin client I can't see anything on lsusb or dmesg I can't understend before this instalation when I connect arduino on thin client I see it on server now I don't see it
