Bug#978: change set-kbd option default to 1 on mac osx clients
by joerg＠hydrops.han.de 07 Jan '16

07 Jan '16

Package: x2goclient Version: 4.0.5.0 This bug affects mac clients only. Systems: OSX 10.6.8 + XQuartz 2.7.5 from macports OSX 10.10.5 + XQuartz 2.7.5 from macports Hi, Problem: The keyboard works fine in x2goclient session (if xmodmap is found at hardcoded path "/opt/X11/bin/xmodmap")(see Bugs #487 and #977) only using virtualbox gives a completely garbled keyboard. Explanation for the virtualbox part: virtualbox on a linux host has to find a mapping from X11 keycodes to scancodes that are to be sent to the guest system. It uses three methods to guess this mapping: "byXKB", "byType" and "byLayout". All three methods look at the keycode to keyname mapping of X11, if method "byXKB" gives a result that matches one of several known keyboard layouts, this result is used. Failing this, the results of the other two methods are checked. This works quite well for - linux local access - native X11 remote access from linux client systems - x2goclient access from windows clients - x2goclient access from linux clients but it does not work for x2goclient access from mac clients, because the x2goserver provides bogus keynames for the XkbGetKeyboard() call. This could be fixed using the x2goclient command line parameter --set-kbd=1 because then x2goserver uses some other way to set up XKB key mappings. This method results in virtualbox getting a good keyname to keycode mapping with XkbGetKeyboard(). I have not seen any problems with other X11 clients using the --set-kbd=1 parameter. Unfortunately the parameter value for "--set-kbd" is silently overridden for max osx client in onmainwindow.cpp to 0 . I spent some hours of testing and looking at the source code of virtualbox, x2goserver, the nx part of x2goserver and at last found this code in onmainwindow.cpp: #ifdef Q_OS_DARWIN usekbd=0; type="query"; #endif in two places. I changed it to "usekbd=1" and virtualbox found a perfect keycode to scancode mapping. As I did not find any problems using this setting, I suggest to use usekbd=1; type="query"; as default for x2goclient on OSX. Joerg

I couldn't understand the status of bug #922 ?
by Eliezer Croitoru 04 Jan '16

04 Jan '16

I have this issue which I am connecting to two hosts and they have the same DISPLAY ports "50". The simple solution is to edit the "x2gostartagent" on the server which works. But I have seen this post: http://permalink.gmane.org/gmane.linux.terminal-server.x2go.devel/10174 Which contains some kind of randomization of ports but I am unsure if x2goagent was patched with it or not, what is the status of this bug? What is required for it to work? Eliezer

And has anyone ever seen setups where the IPv6 traffic is routed via a different interface compared to IPv4 traffic? Furthermore, within the last years, I never had any problems with server-side ports being the same on different servers. I mostly connect through PyHoca. So if there is a problem in X2Go Client regarding server-side SSH tunnel ports, why--the hack--do you fix that in X2Go Server? If the port allocation is a problem at all, it certainly is a problem that requires fixing in X2Go Client, not X2Go Server. Please consider reverting this flawed patch!!!

gnome-sessions on Ubuntu 15.10+
by Eugene San 24 Dec '15

24 Dec '15

Hi all. I am trying to fix gnome sessions (gnome flashback) on Ubuntu 15.10+. I started with fixing session name (flashback -> flashback-metacity) and disabling acceleration check (--disable-acceleration-check), but the sessions are still broken, they start as a black screen and crashes after few minutes. Logs are inconclusive. I guess services are failing to start and the problem is related to recent systemd-user-init and upstart mixture for sessions start-up. Can anyone educate me how exactly the sessions are starting in recent releases and where the problem might be? Thanks.

Bug#645: (no subject)
by Miguel Dilaj 21 Dec '15

21 Dec '15

Hi all, If you are using JDK8, and running the offending program using strace causes entries like this one: java.lang.ClassCastException: sun.awt.image.BufImgSurfaceData cannot be cast to sun.java2d.xr.XRSurfaceData Then it's not an X2Go bug, it's a Java bug. See http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7172749 Many Java programs are affected when run over X2Go. The only workaround I've found is downgrading to JDK7, where the bug is not present. Presumably Oracle will solve it in JDK9, but I don't have the time to extensively test it. Hope that helps! Kind regards, Miguel

Bug#974: Server side disk full issue fails to communicate error to client
by Brian Bourke-Martin 21 Dec '15

21 Dec '15

package: x2goserver Version: 4.0.1.19-0~1064~ubuntu14.04 My x2goclient was hanging after a ssh connection was being made to the server and after a fair amount of time attempting to sort out what when wrong I ended up having to cut and paste the bash remote commands over a ssh session to figure out that a different service filled the disk. Obviously the disk filled issue is not an issue for x2go, but it would make life much easier if the error output from the remote commands could be relayed back to the client for display to the user.

Bug#972: x2go client crashes after moving primary key
by Dennis Jaheruddin 15 Dec '15

15 Dec '15

Package: x2goclient Version: 4.0.5.0 After moving the (folder containing the) primary key that was needed for my session , I tried to connect and got the message "x2goclient.exe has stopped working". I understand that it cannot connect to the session without primary key, but it should not crash on this, but rather return a message like "Primary key file not found at ...". This would help people a lot who try to use a session after some time has passed between projects, as the current error message does not give any hint on what the problem might be.

Central Settings for X2Go Client
by Oleksandr Shneyder 14 Dec '15

14 Dec '15

Hi All, there is a new feature in X2Go Client called "Central Settings". With this feature you can control X2Go Client settings for all users on machine in one place. The Client settings could be stored in /etc/x2goclient/config on Linux and Mac and in HKEY_LOCAL_MACHINE\\SOFTWARE\\x2goclient\\config on Windows. if this directory/regkey exists, X2Go Client will read settings from /etc/x2goclient/config/$USER on Linux/Mac and from HKEY_LOCAL_MACHINE\\SOFTWARE\\x2goclient\\config\\%USERNAME% on Windows. if this directory/key not exists, client will read settings from /etc/x2goclient/config/All Users and HKEY_LOCAL_MACHINE\\SOFTWARE\\x2goclient\\config\\All Users Format of the settings is same as in normal mode and could be easily copied from user directory or exported from Windows registry. in "Central Settings" mode all configuration and sessions editing will be disabled for user. Command line options will be also ignored. You can specify new command line parameters separated by semicolon in the "settings" config file. For example for Linux: $cat /etc/x2goclient/config/alex/settings: [General] commandline="--broker-url=ssh://broker/broker.pl;--maximize" for Windows: HKEY_LOCAL_MACHINE\\SOFTWARE\\x2goclient\\config\\alex\\settings commandline --broker-url=ssh://broker/broker.pl;--maximize this feature will be available from "nightly builds" soon. regards, Alex -- ----------------------------------------------------------- Oleksandr Shneyder | Email: o.shneyder(a)phoca-gmbh.de phoca GmbH | Tel. : 0911 - 14870374 0 Ludwig-Feuerbach-str. 18 | Fax. : 0911 - 14870374 9 D-90489 Nürnberg | Mobil: 0163 - 49 64 461 Geschäftsführung: Dipl.-Inf.

Bug#971: Unable to restore session with AD login
by Dario Pilori 04 Dec '15

04 Dec '15

Package: x2goserver Version: 4.0.1.19 Hello We are using x2goserver on a Ubuntu 14.04 server, which is member of an AD domain. Users have usernames like "DOMAIN\user". After closing bug #664, users can successfully connect to x2goserver, but they cannot resume a suspended session. Every time the same user connects, x2go opens a new session. Logging in as a regular user via SSH, typing x2golistsessions does not return any output, even if the user has several sessions open. If root runs x2golistsessions_root, it displays all sessions, but in the username field of the table it is displayed the user as "DOMAINuser", without the backslash \. Using PostgreSQL database as a backend instead of SQLite3 fixes the problem. Best regards, Dario

Hmm, it appears that the code never calls ssh_options_parse_config(), whether by intention or not I do not know. CCing the dev list to get their take on it. But the libssh docs indicate that it should be called: http://api.libssh.org/master/group__libssh__session.html#ga7a801b85800baa3f… And I can confirm that x2goclient does appear to forward the SSH_AGENT at least if using the ssh-agent for authentication to the remote server. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA/CoRA Division FAX: 303-415-9702 3380 Mitchell Lane orion(a)cora.nwra.com Boulder, CO 80301 http://www.cora.nwra.com

Bug#914: Logout issues, solution
by Maarten Boekhold 22 Nov '15

Hi, Have the same issue on Linux Mint 17.2 and Centos 7 with xfce4-session. I accidentally seem to have 'fixed' this. While debugging some other startup issue, I wrote a wrapper script around xfce4-session ('my-xfce4-session') which looked like: #!/bin/bash xfce4-session > ~/logfile 2>&1 After this, logging out works normally. I had a look at ~/logfile, and xfce4-session spits out quite a bit of text during logout, which I guess confuses x2go. replacing "~/logfile" with "/dev/null" nicely solved it on my other machine as well.

Bug#966: x2goclient SSH fails with keyboard-interactive + banner
by Andrew Cherry 20 Nov '15

20 Nov '15

Package: x2goclient Version: 4.0.5.1 On our systems, security policy requires us to use OTP tokens for login, which means that all SSH connections are keyboard-interactive. In addition, we use /etc/issue.net to print a warning banner before the SSH password prompt. When x2goclient connects, the string variable containing the output for the password prompt ('pr' in sshmasterconnection.cpp) includes the banner as well, and since the check for "Password: " is a strict equality check, the password prompt is not recognized. The simple patch below seems to do the trick to get around this issue: --- sshmasterconnection.cpp 2015-11-20 11:37:44.000000000 -0500 +++ /Users/acherry/sshmasterconnection.cpp 2015-11-20 11:37:24.000000000 -0500 @@ -866,7 +866,7 @@ x2goDebug<<"Prompt[0]: |"<<prompt<<"|"<<endl; #endif QString pr=prompt; - if(pr=="Password: ") + if(pr.endsWith("Password: ")) { #ifdef DEBUG x2goDebug<<"Password request"<<endl; @@ -874,7 +874,7 @@ ssh_userauth_kbdint_setanswer(my_ssh_session,0,pass.toAscii()); return userChallengeAuth(); } - if(pr=="Verification code: ") + if(pr.endsWith("Verification code: ")) { #ifdef DEBUG x2goDebug<<"Verification code request"<<endl;

Bug#963: x2go session environment broken
by Henning Schild 16 Nov '15

16 Nov '15

Package: x2goserver Tag: patch Version: bfe3ba761c1d3e9143285ca17edc87ac763ce35d Hi, i have been using x2go for years, also on servers where i needed to set environment variables for proxies etc. A regular x2go-session fails to include stuff that is configured in /etc/env.d/ and /etc/profile.d/. I think those directories are actually distro specific, the solution is to start everything in a login shell. For me the attached patch helps setting environment variables on several debian systems, i did not test on other distros. Henning

Bug#962: windows8 pyhooca - diacritics in username
by Ja Bi 15 Nov '15

15 Nov '15

Package: windows pyhoca-gui Version: 0.5.0.4 I have pyhoca windows8 client and username with diacritics (Klára) what causes 2 problems (i think) 1) it is not possible to save users pyhoca config to her homefolder. (C:/ Users/Klárka/...) 2) I think there is problem with fuse: server ~ # mount | grep fuse Kl�ra@178.255.168.39:/cygdrive/C/Users/KLRA~1/X2GO~1/S-5C91~1/spool on / tmp/.x2go-x2gotest/spool/C-x2gotest-50-1446557833_stDLXDE_dp24 type fuse. sshfs (rw,nosuid,nodev,default_permissions,user=x2gotest) there is "Kl�ra" and "...cygdrive/C/Users/KLRA~1..."

Hi Stefan (Baur), hi all, @Stefan: on an event in Frankfurt, you had X2Go Client as thin client running on a Rasberry Pi. How much effort would it be to make such image available for the public? @all: does anyone of you have Rasberry Pis running a minimal X2Go (Thin) Client system and are you willing to share (a) the installation procedure or (b) the SD Card image?

Bug#923: .xsession-x2go-errors improvements
by Orion Poplawski 22 Oct '15

22 Oct '15

Package: x2goserver Version: 4.0.1.19 First issue is that ~/.xsession-x2go-errors is always appended to so it grows forever. It should at least get rotated to .old file. Second is with shared NFS home directories, multiple X2Go sessions get logged to the same file which is confusing. I would suggest putting the host name into the log file name. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 http://www.nwra.com

x2go client session kicks user back to the session login screen
by Real, Elizabeth (392K) 21 Oct '15

21 Oct '15

Hello, I have a user who is not able to connect to an x2go server using x2go client for Mac. When I connect to the x2go server in question I am able to successfully connect and login. I’ve compared settings between the user’s and my Mac x2go client and they are identical. I’ve attached screen shots of the client session details. The last messages in the session are: * Info: Your session was closed before reaching a usable state. * Info: This can be due to the local X server refusing access to the client. * Info: Please check authorization provided by the remote X application. * Session: Session terminated at x2go client: v4.0.4.0 xquarts: v2.7.7 Tried uninstalling the x2go client and installing it again but that did not help. Same errors while attempt is made to connect to x2go server. Please advise. Thank you, Liz

I had a similar issue while connecting from X2Go Client v. 4.0.5.0 on MS Windows to X2Go Server v. 4.0.1.19-0~1064~ubuntu14.04.1 on Linux Mint 17.2 (using MATE session): the user was kicked back to the session login screen. The problem was in the .Xauthority* files in the user's home directory on the server side. One of the files was owned by the root, which was a problem. The user solved the issue by running the following command on the X2Go server: sudo rm ~/.Xauthority* Hope this helps. -- rpr.

Bug#958: Xsession startup: LD_LIBRARY_PATH in STARTUP var breaks Debian/Ubuntu/Mint session startups
by Mike Gabriel 19 Oct '15

19 Oct '15

Package: xserver-xsession Severity: important Version: 4.0.1.19 Several /etc/X11/Xsession.d scripts on Debian and Ubuntu (and other derivatives) fail (don't get executed), because they try to detect a variable $BASESTARTUP from $STARTUP which gets set during the Xsession startup mechanism. The detection code expects the session command (mate-session, startkde, xfce4-session, etc.) as the first element in $STARTUP when splitting the $STARTUP string at every blank. As x2goruncommand prepends a LD_LIBRARY_PATH to the STARTUP command (for enabling Xinerama in X2Go sessions), this distro-specific detection mechanism fails. Why report this issue to X2Go then (and not to Debian). Easy reasoning... With nx-libs 3.6.x, the Xinerama code will be completely rewritten and it won't be necessary to set a customer LD_LIBRARY_PATH anymore. Thus, we should make sure, your X2Go Xsession startups get aligned with distro-specific expectations.

Plans for a 4th X2Go Developer Online Meeting
by Stefan Baur 19 Oct '15

19 Oct '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 [please respect the Reply-To header and do not crosspost to x2go-dev] Hi everyone, it's been a while since the last X2Go developer online meeting took place. I've talked to h1, who is in charge of coordinating these events, and he has indicated that 2015-10-22 would be the earliest date possible for him.

Bug in Upgrade Process - Debian Wheezy/Jessie
by Stefan Baur 16 Oct '15

16 Oct '15

Hi everyone, I just stumbled over a nasty bug, but I'm not sure if it is a bug that is limited to X2Go, or if Debian/apt/dpkg is at fault here. Situation: I would like to upgrade a system from wheezy to jessie. This system is running X2Go stable. Step 1: s/wheezy/jessie/ in sources.list Step 2: apt-get update Step 3: Try any of the following: apt-get install x2goserver # when it's already present in # it's wheezy incarnation apt-get upgrade apt-get dist-upgrade and you will see that all X2Go packages remain in their wheezy state. Step 4: Force the installation of the exact version of x2goserver. apt-get -t jessie install x2goserver=4.0.1.19-0x2go2+git20150608.1064+jessie.main.1 And tadaa, we get a hint at what's going on: Reading package lists... Building dependency tree... Reading state information... The following packages were automatically installed and are no longer required: libfile-readbackwards-perl libglib1.2ldbl libgtk1.2 libgtk1.2-common libmozjs24d libnet-daemon-perl libnx-x11 libplrpc-perl libtommath0 xulrunner-24.0 Use 'apt-get autoremove' to remove them. Suggested packages: x2goserver-compat x2goserver-fmbindings x2goserver-pyhoca The following packages will be REMOVED: x2goserver-extensions x2goserver-printing x2goserver-xsession The following packages will be DOWNGRADED: x2goserver 0 upgraded, 0 newly installed, 1 downgraded, 3 to remove and 782 not upgraded. Need to get 85.5 kB of archives. After this operation, 360 kB disk space will be freed. Do you want to continue [Y/n]? apt-get believes it is DOWNGRADING even though we're actually trying to perform an update. Looking at the version numbers given... 4.0.1.19-0x2go2+git20150608.1064+jessie.main.1 4.0.1.19-0x2go2+git20150608.1064+wheezy.main.1 ... it becomes obvious - apt does a numerical/alphabetic sort, and the only difference in those two version strings is "jessie" vs. "wheezy", with the "w" in wheezy being "higher" than the "j" in jessie. Is this something we can fix on our own, by using numeric release numbers (7 for wheezy, 8 for jessie), or is this actually a bug that needs to be reported upstream, because maybe apt shouldn't act that way, and "latch" onto the release name instead of adding it to the numerical/alphabetic sort? If it is entirely our own bug, what should I file it against? Picking out a particular package doesn't seem to make sense, they will all be affected. Do we have a meta-category for that?

Bug#957: x2goserver authenticates session but does not start xfce

When i connect from my workplace (debian stable) the hostkey is stored and then the session is closed. I have the same behaviour, when i connect from a windows client. I have both clients configured to start xfce that is installed on the server. When i use mobaxterm (with its own xserver) on Windows, i can call 'startxfce4' successfully. When i start it on my debian workplace, it fails because i have xfce running locally. Because the x2goclient window closes so fast, i can not read the last lines. One thing that might help: The server is running a Java Application from HP (SSMP). This Java Server binds to the IPV6 Interface of the server. That made me disable the complete IPV6 Config of the server. As result i had to set 'Addressfamily inet' in the sshd config to make X11 tunneling over ssh work. kind regards - -- Hans-Joachim Hoetger "Zwei Dinge sind schädlich für jeden, der die Stufen des Glücks will ersteigen; Schweigen, wenn Zeit ist zu reden, und Reden, wenn Zeit ist zu schweigen."

Bug#765: Kex Error in X2Go client
by rpr nospam 08 Oct '15

08 Oct '15

Hi! I also saw this issue while trying to connect with X2Go Client for Windows (v. 4.0.5.0) to x2goserver (v. 4.0.1.19-0~1064~ubuntu14.04.1) on a Linux Mint 17 machine. The connection worked fine until the SSH server on the Linux machine was reconfigured in order to harden it (see the recommendations in https://stribika.github.io/2015/01/04/secure-secure-shell.html) That reconfiguration allowed only the following host keys and key exchange algorithms: HostKey /etc/ssh/ssh_host_ed25519_key HostKey /etc/ssh/ssh_host_rsa_key KexAlgorithms curve25519-sha256(a)libssh.org,diffie-hellman-group-exchange-sha256 The Elliptic Curve Digital Signature Algorithm (ECDSA) (and the corresponding /etc/ssh/ssh_host_ecdsa_key) is not enabled because its implementation may use a faulty pseudo-random number generator (i.e. containing a back door created by NSA) as explained in some pages referred by the aforementioned article. After some investigation I found how to get rid of the error: in C:\Users\username\ssh\known_hosts remove the line corresponding to the x2goserver host and ecdsa-sha2-nistp256 key exchange algorithm: x2goserver_host_address ecdsa-sha2-nistp256 ... -- rpr.

Bug#955: x2gosid sanitizer check in x2gosqlitewrapper.pl / x2goserver-4.0.1.19-1.1.x86_64 rpm for opensuse 13.2
by Frank Knoben 07 Oct '15

07 Oct '15

Package: x2goserver Version: 4.0.1.19-1.1 File: x2gosqlitewrapper.pl Subroutine: sanitizer Operating System: openSuSE 13.2 64bit Hello, on my system, there are a lot of users, whose username consists of only numbers. In the latest x2goserver rpm for my opensuse 13.2 system (x2goserver-4.0.1.19-1.1.x86_64) there seem's to be something wrong with the sanitzer check function in x2gosqlitewrapper.pl. For the users, whose username contains only numbers, I get the error message of a malformed session id. When I don't do a sanitzer check on the x2gosid, everything is fine. Unfortunately, I have not learned the perl programming language and I'm not so good with regular expression, that I do know how to fix the problem correctly. For me, I just put a return $string; after the elsif ($type eq "x2gosid") { and everything works fine for me again. Sincerly Frank Knoben

Bug#112:
by Bryan Berndt 06 Oct '15

06 Oct '15

Seems I’ve come across a similar bug. I can use x2go to connect to a Fedora 22 workstation running XFCE. While using the small keayboard on my iMac, and using a large Apple keayboard and the built in macbook pro keyboard, everything works fine. Keys work as expected, for the most part. While in the XFCE session, I fire up VirtualBox running a Windows 7 VM. Trying to use this, is where my keyboard no longer works at all. Looks like the same mappings as in post #47. Am unsure how to proceed to work around. May just end up using VirtualBox built in remote connection for access to it. Bryan Berndt bryanb(a)bryanb.net

debian jessie general protection trap in libNX_X11.so.6.2 caused by some apps

Hi all! Long time x2go user. Just remade my box with debian jessie. Followed the server instructions steps. I can run xterm and other programs, but some (like gnome-terminal, xfce-terminal, mate-terminal ... and others) cause x2goagent to crash with: traps: x2goagent[8626] general protection ip:7fdf1317fe6d sp:7ffe79b7dd70 error:0 in libNX_X11.so.6.2[7fdf13133000+123000] This is using today's nightly build. Wondering how to proceed now. Sources build to get more debug information? FYI, I am a general software and linux kernel developer but am not familiar with the x2go project development. Thanks!

The $STARTUP env variable will be set for every Xsession based X11 session on a Ubuntu or Debian (and alike). Please do a grep on /etc/X11 and see its output (grep -r STARTUP /etc/X11). In case you want to use $STARTUP in your own scripts, please know that it is not a good idea to use that var name on Debian nor Ubuntu systems. Using X2GO_STARTUP or any other variable name will not work with existing scripts in /etc/X11/Xsessions.d. Thus, closing this issue and tagging as "not-a-bug".
