x2go vs synergy vs NX vs vnc, etc. (keyboard grab)
by Les Mikesell 17 Mar '14

17 Mar '14

I run synergy (http://synergy-foss.org/) to share my desktop keyboard/mouse with a laptop sitting to the side, and run an assortment of remote-access tools (x2go, NX, vmware client, vnc, etc.) that also grab the mouse/keyboard/clipboard. Sometimes it seems like x2go is conflicting with synergy but it is not very consistent - and sometimes anything that keeps the network very busy will make synergy unresponsive. Is there any way to tell what is really going on? -- Les Mikesell lesmikesell(a)gmail.com

Win32 X2Go Client: Please Test nightly 4.0.2.0 build with PulseAudio 5.0
by Michael DePaulo 16 Mar '14

16 Mar '14

http://code.x2go.org/releases/binary-win32/x2goclient/heuler/mingw32-4.4/qt… Notes: 1. I am not submitting the attached patch for inclusion via this mailing list. I already have commit/push access. I will commit & push it once it is tested enough. It will be the commit for bug 422. 2. "--console" is enabled for x2goclient.exe, that's why you see a terminal open up when you launch X2Go Client. When 4.0.2.0 is released, this will be disabled. 3. If 4.0.2.0 were to be released tomorrow with this patch, the installer will be more like 24.8 MB, not 30.7 MB. This installer is larger because I included the pulseaudio source code, and because I included lots of unneeded pulseaudio modules (.DLL files.) 4.

Buggy File & Folder sharing
by Thierry Kauffmann 14 Mar '14

14 Mar '14

Hi, File & Folder sharing seems to be buggy : I works well for me, using x2go client 3.99.0.5 on ubuntu 12.04 64bits. x2gomountdirs succeeds in mounting local folders. It uses sshfs adresses in the form local_client_user_name@127.0.0.1:server_port/local_path Nevertheless, I doesn't work with a Xubuntu 12.04 32bits client neither with a MAC OS X client : x2gomountdirs tries to mount adresses in the form local_path/ - ie not using ssh port forwarding -. It can not succeed since local_path does not exist on the server ! Problem seems to be linked only to client OS configuration : users have well been added to the fuse group on server. Any ideas (client ssh configuration, ...) ? Best regards, Thierry PS : server is a Xubuntu 64bits running x2goserver 4.0.1.13 -- <http://www.fdsweb.univ-montp2.fr> Thierry KAUFFMANN Chef du service informatique (SIF) Tél : +33 4 67 14 31 58 <tel:+33%204%2067%2014%2031%2058> Mail : Thierry.Kauffmann(a)univ-montp2.fr <mailto:Thierry.Kauffmann@univ-montp2.fr> CC 437 - Place Eugène Bataillon. 34095 Montpellier Cedex 5 - FRANCE. www.fdsweb.univ-montp2.fr <http://www.fdsweb.univ-montp2.fr> FACULTÉ DES SCIENCES/ UNIVERSITÉ MONTPELLIER 2

floss weekly podcast?
by Les Mikesell 14 Mar '14

14 Mar '14

Does anyone on the x2go team watch/listen to the floss weekly podcast? http://twit.tv/show/floss-weekly/feed I think x2go would make a great topic if anyone wants to talk about it. Directions for getting a project on the show are on the feed page "Email Randall...". -- Les Mikesell lesmikesell(a)gmail.com

Resolution Problem openSuSE 13.1 vs 12.3 & Debian 7.4.0
by Tobias Hadem 13 Mar '14

13 Mar '14

Hi everybody, i am testing openSuSE 13.1 right now and i have a problem with the automatic setting of a full-screen-resolution. It works without any problem on a Debian 7.4.0 and a openSuSE 12.3, on 13.1 the vertical resolution of 1920 is correct but horizontal resolution is around 1200 instead of 1080. The taskbar on the bottom and the top pixels are outside the screen and the mouse can't reach it. The auto-mounter-pop-up can be half seen, so it looks like 1920x1200 is set. The client is always a windows-x2go-client with exactly the same config, the only difference is a changed ip-address as server so i can test in parallel. Anybody had that problem before? Below is a version-comparison in case that helps. I would love to supply logfiles, i just can't find anything remarkable in syslog and session-log, so i need a hand with that (activate debug, etc) openSuSE 12.3: x2goagent:3.5.0.21 x2goserver:4.0.1.6 xorg-x11:7.6_1-7.1.1 openSuSE 13.1: x2goagent:3.5.0.21 x2goserver:4.0.1.6 xorg-x11:7.6_1-11.3.1 Debian 7.4.0: x2goagent:3.5.0.22 x2goserver:4.0.1.13 x11-common:7.7+3~deb7u1 Thanks a lot!

Issue with heuler?
by Ted Barnes 13 Mar '14

13 Mar '14

Hi All - I've recently have had trouble installing x2goserver in virtual machines using the heuler (nightly builds) mirrors. The install hangs on "[info] Cleaning up stale X2go sessions" which I would guess is odd given that the virtual machine is "brand new" and has yet to run any x2go sessions. Q: is this something on my end, maybe a dns issue? Has anyone else seen this? Thanks!

Re: [X2Go-User] Thin client ISO/USB?

Hi Les, At the studio site you can rebuild a disto and turn them into live-images (usb, iso, virtuals) or installable/deploy-images (usb,iso). On the tab addition-repo's you can search for x2go (that is available on the OBS) It's free of charge, site: https://susestudio.com Amount of time it takes to build varies a lot, from 2 minutes till 30 minutes, depending how busy the engines in the background are. Results can be kept privately, or shared with the community. Just build a stick (460MB download, 1,6GB uncompressed) and an live iso (624MB download, 2GB uncompressed) There is a gallery with pre-defined images, you can use, and you can clone any pre-defined images. For instance, see: https://susestudio.com/search?q=x2go :-)) Hans -----Original Message----- From: x2go-user-bounces(a)lists.berlios.de [mailto:x2go-user-bounces@lists.berlios.de] On Behalf Of Les Mikesell Sent: dinsdag 11 maart 2014 17:35 To: x2go-user(a)lists.berlios.de Subject: [X2Go-User] Thin client ISO/USB?

x2go loadbalancing with HAProxy
by Thierry Kauffmann 07 Mar '14

07 Mar '14

Hi, As promised I tell you about my experience with loadbalancing x2go. I had first tried to use the default loadbalancing setup of x2go broker. It was working fine except that the Windows client was not connecting to the https broker (due to a bug in the client). It has been fixed quickly and I thank the development team for their reactivity. In the meanwhile, I had looked up alternative solutions and here is what I set up : The broker is a simple HAProxy <http://haproxy.1wt.eu/> loadbalancer configured for ssh connections balancing. For us it listens on port 10000 and dispatches ssh/tcp connections over 2 x2go servers on ports 22 (the default ssh port !). The balancing algorithm is based upon source ip hashing : It gives returning users a chance to be sent to the same x2go server next time and have the possibility to resume a suspended session (better than round-robin). Advantages of that solution : - x2go servers are not exposed to the outside world and there is no need to open ports on the firewall for each x2go server : You only need to open ports for the loadbalancer, which you can put in your dmz. - HAProxy cares to dispatch connections only to x2go servers that are up (timeout configuration). - Authentication is only made once on x2go servers (they are configured with ldap_pam). - No need to install a session broker agent on x2go servers. Drawbacks : - When a user connects with a different public ip, he wont probably be sent to the same x2go server where he could have a suspended session. - Authentication is not made by the loadbalancer so there aren't acl management as with the regular x2go broker. - Every connections transit through the loadbalancer so there might be a little overhead. HAProxy is pretty optimized though and it is not noticeable. I join hereby the HAProxy configuration file I am using. It really works fine for us. I hope it will be useful to others.

x2go Mac client and OS X firewall
by R T 06 Mar '14

06 Mar '14

Hello I use x2go 4.1.3 OS X client on Mavericks (10.9.2). It is used to connect to a Linux system, cat /proc/version below: Linux version 3.12.9-301.fc20.x86_64 (mockbuild@bkernel02) (gcc version 4.8.2 20131212 (Red Hat 4.8.2-7) (GCC) ) #1 SMP Wed Jan 29 15:56:22 UTC 2014 % x2goversion x2goagent: 3.5.0.21 x2goserver: 4.0.1.13 x2goserver-extensions: 4.0.1.13 x2goserver-fmbindings: 4.0.1.13 x2goserver-xsession: 4.0.1.13 I use disk sharing between server and client as well. My OS X Firewall is ON, under Options, the “Block all incoming connections” is UNCHECKED, and both “Automatically allow signed software to receive incoming connections” and “Enable stealth mode” are checked. Every time I connect to the server, OS X firewall pops up a message asking 'Do you want the application “x2goclient.app” to accept incoming network connections?’ I have taken the following steps: 1. Clicked “yes”, which adds /Applications/x2goclient.app to the OS X Firewall 2. Remote Login (SSH) is already allowed to receive incoming connections 3. Manually added the following apps to allow incoming connections: - /Applications/x2goclient.app/Contents/MacOS/x2goclient - /Applications/x2goclient.app/Contents/exe/nxproxy - /usr/libexec/sftp-server - /usr/sbin/sshd However OS X still prompts me whenever a connection is made to the remote session, or when a new session is started. How can I stop this annoying message? Thanks Rio
