BKO and USB over IP
by brian mullan 23 Sep '10

23 Sep '10

Speaking of Thin Clients... Although this is not directly related to the Thin Client thread it is something I was impressed with. Boot Kernel Organization (BKO) <http://boot.kernel.org/> BKO is based on a REALLY SMALL linux ... about 1 Megabyte. It can be installed onto just 1 small partition of a USB, CD (or floppy if you have one). Its sole purpose is to boot and provide you with a simple GUI menu system (see pictures on the site) where you can select which OS you want to boot and then *BKO uses HTTPFS to download and boot that OS* for you. NOTE: on their website their list of supported OS and OS version is very outdated. When you actually do this you will see Ubuntu 10.04 desktop and server, you will also see newer versions of fedora as well as other linux distributions. I've started using this with virtual machines. I download the CD ISO and then use that to create a KVM virtual machine instance using that .ISO file. Why? Well I use that 1 KVM VM instance to launch any new VM instance I might need. Since it is only 1 Megabyte in size it boots nearly immediately. I select which Linux distribution I want, what version and the BKO then downloads the selected OS and boots it. It has worked great so far. Off of the BKO FAQ you should note: BKO is based on HTTPFS and it uses only valid HTTP requests. It means, if you have HTTP access, you can boot with BKO. Only problem that may occur is if you are behind HTTP proxy. We plan to add support for HTTP proxy in near future. Stay tuned till then. It is expected that you can use *Public DNS* system as BKO is configured to use Public dns servers instead of the servers provided by user or DHCP. We will be soon fixing this problem. Till then, you are expected to have public DNS access. That 2nd paragraph *I think may be outdated* as I believe you can now install the BKO "server" locally instead of using the BKO.org servers to download from. If you install your own BKO server locally then you "could" install all of the OS's you work with on it. Then you could use your own BKO to select *and more importantly boot a pre-configured OS* !!! I haven't checked but I am wondering if a Windows OS could be booted using BKO as well? I'm thinking you could have something like a preconfigured Ubuntu (or fedora etc) desktop with x2go client configurations and applications already installed and then just use the BKO and their GPXE to boot the clients. I haven't gotten as far as looking into installing it locally so my current workaround is to use BKO to boot then I use the python based Fabric library to automagically provision the OS with x2go, the apps I want etc. Fabric is really simple to use and lets you execute remote commands via scripts so you can for instance install x2go server or client very easily.. After the Fabric script is done my virtual machine has the OS of my choice with all the apps and x2go installed. Another interesting technology I discovered lately and tried out is USB over IP. Perhaps this could be incorporated into a future feature for x2go server & client ??? How To Set Up A USB-Over-IP Server And Client With Ubuntu 10.04 Version 1.0 Author: Falko Timme <ft [at] falkotimme [dot] com> <http://twitter.com/falko> Follow me on Twitter <http://twitter.com/falko> Last edited 01/18/2010 This tutorial shows how to set up a USB-over-IP server with Ubuntu 10.04 as well as a USB-over-IP client (also running Ubuntu 10.04). The USB/IP Project<http://usbip.sourceforge.net/>aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates "USB I/O messages" into TCP/IP payloads and transmits them between computers. USB-over-IP can be useful for virtual machines, for example, that don't have access to the host system's hardware - USB-over-IP allows virtual machines to use remote USB devices. I do not issue any guarantee that this will work for you! 1 Preliminary Note This tutorial is based on AliRezaTaleghani's tutorial How To Modify Your Gnu/Linux Box To Serve As A USB Over IP Server<http://www.howtoforge.com/how-to-modify-your-gnu-linux-box-to-serve-as-a-us…>, but I've adjusted it for Ubuntu 10.04 (server and client). If you want to use a Windows client, please take a look at AliRezaTaleghani's tutorial - that part is still the same. In this tutorial I use the server server1.example.com with the IP address 192.168.0.100 and the client client1.example.com with the IP address 192.168.0.101, both running Ubuntu 10.04. These settings might differ for you, so you have to replace them where appropriate. 2 Installing And Using USB/IP On The Server server1: We can install usbip as follows: aptitude install usbip Afterwards we load the usbip kernel modules: modprobe usbip modprobe usbip_common_mod To check if they really got loaded, run: lsmod | grep usbip The output should be similar to this one: root@server1:~# lsmod | grep usbip usbip 15124 0 usbip_common_mod 13605 1 usbip root@server1:~# To make sure that both modules get loaded automatically whenever you boot the system, you can add them to /etc/modules: vi /etc/modules [...] usbip usbip_common_mod Now we can start the usbip daemon: usbipd -D root@server1:~# usbipd -D Bind usbip.ko to a usb device to be exportable! root@server1:~# Now attach a USB device that you want to export to the server - I'm using a SanDisk USB flash drive here. Execute the command lsusb to find the corresponding Vendor/Device ID which is in the form of: Bus XXX Device YYY: ID VendorID:DeviceID The output on my server is as follows: root@server1:~# lsusb Bus 001 Device 002: ID 0781:5151 SanDisk Corp. Cruzer Micro Flash Drive Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub root@server1:~# The Vendor/Device ID of my SanDisk USB flash drive is 0781:5151. Now run usbip_bind_driver --list The output on my server is as follows: root@server1:~# usbip_bind_driver --list List USB devices - busid 1-1 (0781:5151) 1-1:1.0 -> usb-storage root@server1:~# As you see, the Vendor/Device ID of my SanDisk USB flash drive (0781:5151) corresponds to the BUSID 1-1. We need this BUSID to attach the USB device to the server: usbip_bind_driver --usbip 1-1 root@server1:~# usbip_bind_driver --usbip 1-1 ** (process:765): DEBUG: 1-1:1.0 -> usb-storage ** (process:765): DEBUG: unbinding interface ** (process:765): DEBUG: write "add 1-1" to /sys/bus/usb/drivers/usbip/match_busid ** Message: bind 1-1 to usbip, complete! root@server1:~# That's it, we can now use the SanDisk USB flash drive on a remote usbipclient. BTW, if you run... netstat -tap ... you should see that the usbip daemon is listening on port 3240 so please make sure that this port isn't blocked by your firewall: root@server1:~# netstat -tap Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:ssh *:* LISTEN 537/sshd tcp 0 0 *:3240 *:* LISTEN 762/usbipd tcp 0 52 server1.example.com:ssh 192.168.0.199:4024 ESTABLISHED 667/0 tcp6 0 0 [::]:ssh [::]:* LISTEN 537/sshd root@server1:~# Copyright © 2010 Falko Timme All Rights Reserved. How To Set Up A USB-Over-IP Server And Client With Ubuntu 10.04 - Part 2 3 Installing And Using USB/IP On The Client client1: We must install usbip on the client as well: aptitude install usbip Afterwards we load the vhci-hcd kernel module: modprobe vhci-hcd To check if it really got loaded, run: lsmod | grep vhci_hcd The output should be similar to this one: root@client1:~# lsmod | grep vhci_hcd vhci_hcd 19800 0 usbip_common_mod 13605 1 vhci_hcd root@client1:~# To make sure that the module gets loaded automatically whenever you boot the system, you can add it to /etc/modules: vi /etc/modules [...] vhci-hcd Now connect to the usbip server and get a list of available USB devices: usbip -l 192.168.0.100 (192.168.0.100 is the IP address of the usbip server.) You should find the SanDisk USB flash drive in the output (BUSID 1-1): root@client1:~# usbip -l 192.168.0.100 - 192.168.0.100 1-1: SanDisk Corp. : Cruzer Micro Flash Drive (0781:5151) : /sys/devices/pci0000:00/0000:00:07.2/usb1/1-1 : (Defined at Interface level) (00/00/00) : 0 - Mass Storage / SCSI / Bulk (Zip) (08/06/50) root@client1:~# To attach that device to the client, run: usbip -a 192.168.0.100 1-1 root@client1:~# usbip -a 192.168.0.100 1-1 8 ports available port 0 attached root@client1:~# Now run... lsusb ... and you should find the remote USB device in the output on the client: root@client1:~# lsusb Bus 001 Device 002: ID 0781:5151 SanDisk Corp.

x2go client for Ubuntu ARM?
by Jo-Erlend Schinstad 23 Sep '10

23 Sep '10

I'm currently working on the IGEPv2 board, and it's mostly working. I'd really like to see how well it works with x2go. Is there any packages for Ubuntu ARM? Thanks, Jo-Erlend Schinstad

Re: [X2go-dev] X2go-dev Digest, Vol 21, Issue 23

I've tried nearly all of the leading remote desktop technologies that I could find. Remote Video is hard to improve on any of them without taking a different approach that frame buffer forwarding. So NoMachine's NX, Citrix's remote desktop technology etc all are limited by bandwidth constraints of trying to push full motion video frame buffers across a WAN link.. no matter how good the compression. Which by the way also affects video quality because of delay. There are solutions out there that are trying to address this in a different architectural way such as the Spice client & server architecture which does the video processing at the client and more or less sends gui control cmds over the net. There is also PCoIP (PC over IP) which works very well at full motion video and also 3D video BUT it requires hardware installed at the server side and also a PCoIP card at the Client side... so its not cheap. I think there are 2 other things that should impact the performance current NX related solutions: 1) I recently read that several NX solution vendors are now using *libjpeg-turbo *instead of the older libjpeg. *http://libjpeg-turbo.virtualgl.org/* * It's a high-speed version of libjpeg based on libjpeg/SIMD but with additional optimizations and support for 64-bit platforms (and neatly* * packaged into an SDK that can install on most types of x86/x86-64 systems.) It's 2-4x faster than libjpeg and GPL-compatible, so I would* * imagine that NX related remote desktop solutions like x2go, FreeNX and NX from NoMachine itself woul all benefit from it performance-wise.* *NOTE: when I first tried libjpeg-turbo I installed it only on the client and I didn't seem much if any change. However I recently learned that actually has to be innstalled on BOTH server and client to see the performance benefit but in a recent test I saw the results of increased performance 180%. BUT - I'd still recommend running Browser based video like YouTube off of the local Client machine instead of over the Internet from a remote desktop. * *2) HTML 5 with its enhanced support for multimedia (video & audio)* * Brian * > > Am Mittwoch, den 22.09.2010, 21:56 -0600 schrieb Dimitris Anogiatis: > > Dear List, > > > > > > Does anyone know of any advantages from installing a hardware ssh (or > > crypto) accelleration device on a server machine running x2go? > > For example I've tried to tweak my SSH server but despite some > > improvements in responsiveness video playback (I tried a youtube > > video) is still choppy. > > > > > > Would a device like that help or does x2go's design not allow it to > > benefit from such an enhancement? > > > > > > I'm using my x2go client from a remote location using wifi and not in > > a LAN. > > > > > > Regards, > > Dimitris > > _______________________________________________ > > X2go-dev mailing list > > X2go-dev(a)lists.berlios.de > > https://lists.berlios.de/mailman/listinfo/x2go-dev > > > **************************************** >

Installing on Ubuntu Lucid/KDE4?
by Matthew Macdonald-Wallace 23 Sep '10

23 Sep '10

Hi all, I've been setting up a thin-client solution based upon x2go and I'm interested in seeing if it will work with KDE4 on Ubuntu Lucid/Maverick. The issue I've run into is when installing the x2goldapadmin tools the installation borks out stating that kcontrol is not available. Does anyone know if packages are available for the above combination? Thanks, Matt

GPL violations
by Jörg Sawatzki 23 Sep '10

23 Sep '10

Hey list, I just got an email back from Heinz - a private mail! You know that I have been discussing about the plugin and sources with him and Alex on this list for a couple of months now. Other people have asked as well where the sources for the plugin are. Obviously they think that I cannot read C++ code and sent me the link to the plugin.cpp source (http://x2go.obviously-nice.de/mozplugin/) again - in the hope that I believe them. But unfortunately I had a look into the code (trying to build it) and saw that it executes a binary: an extended version of x2goclient with heaps of new command line options. Asking for the source (which is your and my right according to GPL) I got one of these famous excuses saying "oh, we are in the process of changing to QTBrowserPlugin" and so on. In short: 99% of x2goplugin's sources are not published - this affects (modified and not modified) third-party components as well. Everybody who publically distrubtes GPL software in binary form and does NOT provide a link to the sources violates the license. The GPL doesn't say "if you have time and the weather is nice you can publish the sources if you want to". Therefore I would not recommend anybody to use the plugin in a production environment and integrate it into any project! It will be you who will get into court if one of your customers enforces his GPL rights and you have distributed it in your project. Just to let you know: I feel a bit fooled with all the excuses and that they try to somehow get around legal requirements by sending me some stuff that's only a 7.5K file wrapping around the actual component. In my opinion, the way they deal with community input/ideas/contributions is ignorance. Nothing of the critics and proposals was taken seriously. We still don't have a GIT repo - and that would take them 5 minutes or less! But that's alright - we don't have to have git. But we HAVE to follow legal requirements in the GPL. And not next year, but NOW! I spent a lot of time and energy into this and the result: I am maintaining my own python code externally now, because they don't let me contirubte! And the worst result: I am frustrated as hell, that I spend months waiting and writing dozens of mails to enforce my rights that I have by law. After all, I'd just like to inform all of you, that I am going to report this to gpl-violations.org as after explaining it again and again I still see no change. I'll inform NoMachine as well and advise them to enforce their legal rights as well - it is their code as well! I am sorry for bothering you with this, but I think it is important to draw things like this into plubic attention Jörg

Joerg You just said in one of your responses... "*I am asking for the source for a month or two*".. Okay... - Alex was on vacation a month ago. - Heinz is on vacation now - each was 1 month off. I know it was thoughtless of them to take vacations and I'm sorry their responsiveness didn't meet your needs. You DO have choices... 1. wait until the new x2go is actually released and then see if you can get what you want 2. go elsewhere and find another solution such as: - NoMachine's NX v4.0 is do out soon - FreeNX - NeatX - or look into the Spice client & server software from Red Hat. Thanks for your comments and opinions but I'm not sure the discussion is very productive at this point and perhaps the forum could go back to answering other questions?

Plugin building
by Jörg Sawatzki 22 Sep '10

22 Sep '10

Hi Heinz, Alex and list, as there are lots of questions and wishes arising on this list and by my customers, I'd like to build my own version of x2goplugin and x2goclient to be able to play around and implement new things. As you told me some days ago, the plugin source is here: http://x2go.obviously-nice.de/mozplug/ That is indeed true - but where's the rest of it? As far as I can tell from the code, it starts an instance of x2goclient with some "secret" command line options. Where is that modified x2goclient's source? It's not the 3.01 x2goclient that is floating around around somewhere in x2go.obviously-nice.de/deb, is it? Thanks, Jörg

Re: [X2go-dev] X2go-dev Digest, Vol 21, Issue 18

Joerg I agree with John in his view of Hienz and Alex. They are good folks BUT everyone has to remember they are ONLY 2 people ! They have a separate life where they have to earn money to support themselves & families too. x2go is something they have dedicated themselves to because it aids them in their other income related activities. There's an old saying: Nothings impossible for those that don't do the work. Given that Heinz and Alex have been working for the past year to create this new release of x2go ... again while working on their day jobs ... oh, and while building the new x2go wiki etc. Now that they are in what is hoped to be the final stages and frankly I'd rather they focus on that and worry about where to post the source code when they have some breathing space. Give them a break is my vote. Brian Mullan ------------------------------ > > Message: 3 > Date: Wed, 22 Sep 2010 14:51:42 -0400 > From: "John A.

Resume specific session with x2goplugin
by contact＠gmli.fr 22 Sep '10

22 Sep '10

Hi, (first of all, thanks for your help Heinz and Sven) I would like to know if it's possible to resume a specific session with the plugin ? The goal is to list sessions (with x2golistsessions) on the server, and paste the session id in the x2go.server file in order to resume it. I don't want to use the resuming form showed by the plugin (my users are confused with it). I'm making a webapp, and I would list sessions in a web page, and make it possible to resume paused sessions just by clicking on a link. Thanks in advance ! Regards, Guillaume
