Broker + User-side HTTP(S) proxy
by Mathias Ewald 28 Oct '13

28 Oct '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I am using X2go broker with SSH proxy to have X2go servers sit behind the broker not directly reachable from the internet. Like this, I need Users have access to ports 443 (usually not a problem) and SSH (very often a problem). Problem is that users tend to sit behind transparent http/https proxies, so SSH won't get out. I would like to see everything being done through HTTPs so we can trick proxies. Is this going to be implemented in the near future or maybe even already possible somehow? cheers Mathias -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJSbgt3AAoJEA7RPiZyzgdIIRoP/A4d6rYcYk2NbNW7Zalc5viU u6lDE4KGPl9m7b7TbXs7X30FWGN/1wsyKFo262nrJHUX/UiiWjrIiSlRewxAg2dT AFsiNaLPfQc/GW/nSm0qOdAz/pCBlNTTeNa2HY/K6bOCyzv5kcsuqI8RjDZXV06E /tsvDeD/HR+C8ZHvsnHYDgmn12ftgpS1pJ/P5AM6ATTU3eKDC30OkJ4q46Ykim8W CbrMCDtElEUI3XXi6D33mYWKEAJyrIR10KvFMyZuG4o6E8lq0olT5FCFItyJTV+x i4KJWf/jAM3DDcJFNqICziSnLJcOTGt2PVBe8pZH9uidMVacztoJ0sBlOk/alTe1 nM4zUbToaGA4dwNPgBcJjdmywwXF7rXGqgp8Wm/VJ0u4mobm/NkNbsyWI5Q+TVcO huf250kDaDb8+eqIP23JttKr+FYT3eZ6D5KKIQeYeomgu/zopsPHSFi5gIexQclf 5aT87URNae+efIjayydjyP8DTEFh3Hw1QkdEgJYyfQlgh5lecYdsi+74G8MA3PoI NJpDUPsKtya4gIM3F3fTd3ucxYXXP6Z5qod7pDG6uIEwvImcbT9cbkNidnf01ROE g43lrBrhQ2C3pW2fhQi7skNI4Q2uA1wd1Qq8lPcTxoAl6wY6iS5Wut6aMwyJxmOm z5YtX+C+HkTb7kubtDtP =F+9b -----END PGP SIGNATURE-----

pyhoca-cli sound issues
by Tim Kruse 24 Oct '13

24 Oct '13

Hi all, I have weird sound issues with pyhoca-cli and need a hint, where to look :) Scenario: debian wheezy (uptodate) client with KDE running conncts to a debian wheezy (also uptodate) server with KDE. Following versions: root@client: ~ # dpkg -l | egrep 'x2go|pyhoca' ii pyhoca-cli 0.4.0.1-0~x2go1+wheezy~main~171~build1 all Command line X2Go client written in Python ii pyhoca-gui 0.4.0.8-0~x2go1+wheezy~main~1082~build1 all Graphical X2Go client written in (wx)Python ii python-x2go 0.4.0.8-0~x2go1+wheezy~main~1095~build1 all Python module providing X2Go client API ii x2goclient 4.0.1.1-0~x2go1+wheezy~main~427~build1 amd64 X2Go Client application (Qt4) root@server: ~ # dpkg -l | egrep 'x2go|pyhoca' ii x2go-keyring 2012.07.23+wheezy~main~17~build1 all GnuPG keys of all X2Go developers and the X2Go archive ii x2goagent 2:3.5.0.21-0+wheezy~main~423~build1 all X2Go agent ii x2goserver 4.0.1.6-0~x2go1+wheezy~main~712~build1 i386 X2Go server daemon scripts ii x2goserver-compat 4.0.1.6-0~x2go1+wheezy~main~712~build1 all X2Go server daemon scripts (backwards compatitbity to old client versions) ii x2goserver-extensions 4.0.1.6-0~x2go1+wheezy~main~712~build1 all X2Go server daemon scripts (extensions) ii x2goserver-xsession 4.0.1.6-0~x2go1+wheezy~main~712~build1 all X2Go server daemon scripts (Xsession runner) If I try to connect from client (within a fresh KDE session) to server with the following command, I don't have any sound in this x2gosession: pyhoca-cli --server $SERVER --new --command startkde --username $USR --sound pulse --geometry 1440x900 --link adsl --pack 16m-png-9 --kbd-layout de --kbd-type '105/de' Now I connect to the server (or another x2goserver, that doesn't matter) with x2goclient and there is sound. When I then connect again with above pyhoca-cli command, I have sound in this session. When I restart the local KDE Desktop on the client, I don't have any sound with pyhoca, until I connect with x2goclient ... I think, there is some process/program, that pyhoca-cli is not able to start, until x2goclient will start it, but I can't find it ... Help appreciatet :) So long, Tim

Session Configuration Data
by Short, Kermit 23 Oct '13

23 Oct '13

I'm pleased to say that I've got X2Go client running on an IGEL thin client. To those of you that have helped me get to this point, please accept my sincere thanks. I can't tell you how much I appreciate all the help! My next step is to build a configuration file with all of the various servers that our customers will connect to. Where does all the session configuration data get stored? Is this stuff that I can pass in on the command line? It would certainly be easier to push out a prebuilt (pre-customized) session configuration file to particular thin client devices, but if I have to create a shortcut with command line parameters for each server, I'll do that too. Thanks!! -- Kermit Short DCS-5

more and more sessions
by Mathias Ewald 23 Oct '13

23 Oct '13

Hi, I am connecting to a Ubuntu Desktop over x2gobroker with the following session configuration: host=10.173.20.2 name=Terminal Server sshproxyuser=x2gosshproxy acl-groups-allow=vxltadmins setsessiontitle=true krblogin=false pack=16m-jpeg quality=9 speed=2 usesshproxy=true sshproxytype=SSH sshproxyhost=88.198.244.99 sshproxyport=22 sshproxyautologin=false sshproxysamepass=false sshproxysameuser=false width=800 height=600 dpi=96 fullscreen=false maxdim=false multidisp=false xinerama=false usekbd=true sound=true soundtunnel=true defsndport=false soundsystem=pulse startsoundsystem=true useexports=false useiconv=false iconvform=UTF-8 iconvto=UTF-8 fstunnel=true print=false usemimebox=false mimeboxaction=OPEN autostart=false xdmcpserver=localhost command=XFCE4 published=false command=XFCE acl-groups-deny=ALL acl-clients-allow=ALL acl-any-order=deny-allow sshproxysameuser=false After a while I realized that memory usage went very high on that x2go server and found out I was having 10 sessions running. That makes sense as I always wondered why my sessions are not resumed. So it looks like instead of resuming I get a new session every time. Is there any configuration I am missing that would force resume if there is a session available and clean up sessions after say a timeout or similar? cheers Mathias

x2go session broker & apache
by Ted Barnes 23 Oct '13

23 Oct '13

Hi All: Am experimenting with x2go session broker (am running it in a virtual machine). All in all, I plan to try to run my x2go sessions through an SSL connection to avoid having to manage SSH keys. Because I anticipate a more complicated setup, am trying the "wsgi" option. Installed just fine (apt-get install x2gobroker-wsgi). The documentation mentions using Apache along side (http://wiki.x2go.org/doku.php/doc:installation:x2gobroker: " With Apache2+WSGI...), so I tried to install apache2 but get the following type of error: Starting web server: apache2 Syntax error on line 7 of /etc/apache2/conf.d/x2gobroker-wsgi: Invalid command 'WSGIDaemonProcess', perhaps misspelled or defined by a module not included in the server configuration Action 'start' failed. The Apache error log may have more information. failed! Should I not be trying to install Apache (this is a fresh VM, so apache was not previously installed), or is there some other install or setting I should have done? Thanks!

o
by Short, Kermit 21 Oct '13

21 Oct '13

Greetings! Thank you to everyone who's helped me up to this point!! I've got the x2goclient and seemingly all the required libraries (used objdump -x "x2goclient" | grep NEEDED) to find out all the required linked libraries), and on the thin client I can launch the x2goclient program and the familiar GUI interface pops up. I can create a session as I normally would, and when I double click the session and try and authenticate, the client contacts the remote x2goserver daemon and creates a session. However, that's where everything stops working. I usually get a black window that pops up with an X2Go watermark in it. Eventually my remote graphical desktop appears in this window and I'm off and running. That black window pop up is not happening on the thin client. The display stays on the credential entry screen and the status simply says 'Finished' and the client goes back to it's typical waiting state. If I try to connect again, I can see that a session on the remote server daemon exists. I can suspend or terminate it. If I try to resume or create a new session, the aforemention behaviour is repeated...no black x2go window, just 'Finished' and that's it. Anyone have any ideas? It seems like I'm missing some program or module that the client relies on. Thanks! -- Kermit Short DCS-5

load balanced broker autologin
by Stefan Heitmüller 21 Oct '13

21 Oct '13

Hello everyone... I'm currently evaluating x2go as terminal server solution for our developer linux desktops. So far, it works, great, i'm using it with https session broker and 3 servers (with mate-desktop). Right now, i'm trying to setup load balancing for those servers (see http://wiki.x2go.org/doku.php/wiki:advanced:x2gobroker:loadbalancing) All servers are identical (thanks to puppet, like mentioned in the wiki), user-homes are mounted via nfs, users are mapped from active-directory (samba4) via likewise-open. I can login on every single server without the broker, but when i'm using the broker, i just can login once. The second x2goclient ist listing the load-balanced session profile as in active (so "/usr/lib/x2go/x2gobroker-agent stefan.heitmueller listsessions" seems to work, at least it does on cli), login just throws an error. When watching the logs and personal authorized_key files, i see that the broker is placing the ssh key onto the target server while login to the first session. When logging into the second one, there is no attempt to do so...how is the automatic login done without ssh keys? using postgres database?
