Bug#1280: Resolved
by Ross Mohn 15 Aug '18

15 Aug '18

Installed x2goclient-4.1.2.0-2018.06.22 and performed additional testing. It seems that if I specify a key in the "Use RSA/DSA key for ssh connection" the client doesn't attempt to use the ssh agent at all, only that specific key file. I had thought that it would still try the agent first, but it only tries the specified key file and then moves right to asking for the password, skipping the agent altogether. Next I created a new id_ed25519.ppk file and loaded it with pagent. I leave "Use RSA/DSA key for ssh connection" blank. The client now immediately uses pagent for authentication and launches my session without requiring any further interaction. OK to close, thanks! -Ross

Bug#1319: PulseAudio does not start
by SW＠EU 14 Aug '18

14 Aug '18

Package: mingw32-pulseaudio Version: 7.1 Hi, Windows 10 forced update to 1803 (Pro edition, englisch + German language pack) and x2goclient updated using x2goclient-4.1.2.0-2018.06.22-setup.exe. Since that I have to disable Pulse-Audio because otherwise I get the attached error during any start of the client. I have in meantime uninstalled the the separate installed 64 Bit VcXsrv because the 32 Bit x2goclient installation has changed files in the 64 Bit VcXsrv installation (is this correct?) and uninstalled x2goclient, rebooted, x2goclient again installed but 64 Bit VcXsrv not again, rebooted, but still the same. TIA, Silvio

Bug#1317: extended checks for loadchecker (or broker ... dunno)
by Walid MOGHRABI 13 Aug '18

13 Aug '18

package: x2gobroker version: 0.0.4.0-0~1038~ubuntu16.04.1 priority: enhancement We encountered another corner case very annoying. The whole broker stack does its work quite well when everything works as expected (which is mostly the case). A failing server for example is perfectly handled, loadchecker simply disable this server from the list and thus, broker sends users to remaining live servers. Problems are beginning when your servers misbehaves. Loadchecker mainly checks : * liveness ("ping") * ssh acess * load/memory values This is okay but not enough to be sure that a server can handle incoming connections, for example, for our needs, we should make sure that : * a user can authenticate on a server (Active Directory authentication through PAM/Winbind) * some mounts are correct (/home folders, other user mounts or shares) * some networks are available * some mandatory services are running * ... In our recent problems, for unknown reasons, some servers were having troubles joining the Active Directory domain and thus, user auth was failing. On the broker/loadchecker side, the server is perfectly working and this is even one of the best performing server since it is empty so it allways tries to redirect incoming connections to this server and since users can't auth, it fails and blocks every new connections. With extended checks, this server would have been considered offline from the loadchecker point of view and thus, it would have just been out of the load balancing. Since those checks are pretty "specific", it would be great to have some kind of "extended check" feature where a directory "extra-check.d" folder would exist on the x2gobroker setup in which we could drop some scripts that would be executed by the x2gobroker user on the remote servers with just an "ok" or "ko" value. As soon as you get a "ko" value, the server would be considered unavailable and then removed from load balancing until the next "ok" check. Script could be of any language with supported intepreter installed on the server (could be bash, perl, python or anything, you'll just need the interpreted to be installed but this is the administrator responsibility). --- DISCLAIMER: This e-mail is private and confidential and may contain proprietary or legally privileged information.

Bug#1316: many connections within the loadchecker sleeping time frame
by Walid MOGHRABI 13 Aug '18

13 Aug '18

package: x2gobroker version: 0.0.4.0-0~1038~ubuntu16.04.1 priority: enhancement I'm not really sure of that because it is pretty hard to reproduce that one but I have the impression that, if you have many users connecting nearly at the same time (and especially within the loadchecker sleep time which is 300s by default), the load factor value is not recalculated and thus, you might have many users sent to the same server instead of beeing equally distributed of the farm. Sometime, I have 3, 4, 5 ... users sent to the same server while I have a few servers empty of connected users. This is a race condition but every morning, it can happen since our users starts between 8:30AM and 9:30AM and we have about 100 users so you can easily have 5~6 people connecting in less than a minute. I think the load calculation should be more dynamic and not strictly done every x minutes. For example, you can still do the load calculation every 5mn in order to "reset" load values once but then, I think something like this could be done : * calculate the load every x minutes ("bootstrap" calculation) * user A logging in, broker asks loadchecker for a server to connect the user, loadchecker respond "server-01" * user A is sent to "server-01" and then, "server-01" is locked for a few seconds (5, 10, ... maybe user defined) (blocked for new incoming connections) * broker asks loadchecker to re-calculate the load value for "server-01" only * "server-01" is unlocked for new incoming connections That way, load value is recalculated "on demand" in real time and connections are sure to be retargeted to more available servers while this calculation is done. --- DISCLAIMER: This e-mail is private and confidential and may contain proprietary or legally privileged information.

Bug#1315: loadchecker bad auto sleep time leads to faulty service

package: x2gobroker-loadchecker version: 0.0.4.0-0~1038~ubuntu16.04.1 priority: bug I had a problem with broker loadbalancing not working anymore even though the loadchecker service seemed to work well.

I fixed my "Print" error. I'm still getting high CPU usage with Openbox using x2go and QT apps not opening after the last update.

Bug#1312: Ubuntu 16.04 LTS Qt bug
by e8dude 09 Aug '18

09 Aug '18

Same here. Upgraded my Ubuntu 16.04 LTS. After the upgrade only some of my QT apps work. Stipend wallet works but Apollon and Deviant do not open at all. Since the update I'm also having high CPU usage in Openbox. Logs are filliing up with Print error while x2go is running. If I close x2go CPU usage is normal and error reporting stops. Here is the .xsession-x2go-errors log of a failed QT app that doesn't open nestled in the gazillion Openbox messages that occur running x2go: > Openbox-Message: Requested key "Print" does not exist on the display > > Openbox-Message: Requested key "Print" does not exist on the display > > Openbox-Message: Requested key "Print" does not exist on the display > > Openbox-Message: Requested key "Print" does not exist on the display > > Openbox-Message: Requested key "Print" does not exist on the display > > XIO: fatal IO error 0 (Success) on X server ":50" > > after 280 requests (278 known processed) with 0 events remaining. > > Openbox-Message: Requested key "Print" does not exist on the display > > Openbox-Message: Requested key "Print" does not exist on the display > > Openbox-Message: Requested key "Print" does not exist on the display > > Openbox-Message: Requested key "Print" does not exist on the display

close #1266 thanks Hello, we are very hopeful that X2Go issue #1266 reported by you has been resolved in the new release (4.1.0.1) of the X2Go source project »src:x2goserver«. You can view the complete changelog entry of src:x2goserver (4.1.0.1) below, and you can use the following link to view all the code changes between this and the last release of src:x2goserver. http://code.x2go.org/gitweb?p=x2goserver.git;a=commitdiff;h=885f64e9b7e41c4… If you feel that the issue has not been resolved satisfyingly, feel free to reopen this bug report or submit a follow-up report with further observations described based on the new released version of src:x2goserver. Thanks a lot for contributing to X2Go!!! light+love X2Go Git Admin (on behalf of the sender of this mail) --- X2Go Component: src:x2goserver Version: 4.1.0.1-0x2go1 Status: RELEASE Date: Fri, 27 Jul 2018 06:46:00 +0200 Fixes: 1266 Changes: x2goserver (4.1.0.1-0x2go1) RELEASED; urgency=medium . [ Mike Gabriel ] * New upstream release (4.1.0.1): - x2goserver/man/man8/x2gostartagent.8: Fix grammar flaw reported by Debian's lintian tool. - x2goserver/man/man8/x2goresume-session.8: Fix grammar flaw reported by Debian's lintian tool. - x2goserver-x2goagent/bin/x2goagent: Fix license version (GPL-2+ not 3+). This script however is obsolete and should be replaced by a symlink to $BINDIR/nxagent. - Makefile.docupload: Switch license to GPL-2+. - x2gocheckport: chmod a+x. - x2goserver*/: license header hygene. List all copyright holder above the short form license. This prevents the licensecheck utility from being fooled. - X2Go: more license header hygene. - libx2go-server-db-perl: more license header hygene. - X2Go Agent XPM: Rename from x2go.xpm to x2goagent.xpm. - X2Go XPM icon: white background, not transparent. * debian/control: + Change D (x2goserver-xsession) on perl-modules to perl. The existence of the perl-modules package is an implementation detail of the Debian Perl packaging. + Multiarch hinter script recommends annotating perl dependency with :any. + Bump Standards-Version: to 4.1.4. No changes needed. * debian/copyright: + Update copyright.in reference template. * debian/*: Process with wrap-and-sort -a -s -t -k -b. * debian/x2goserver-printing.postinst: + Make sure /var/spool/x2goprint is always created. * debian/rules: + Add dh-missing --fail-missing override. * debian/*.{install,manpages}: + Utilize install target rather than picking all files from the source tree ourselves. * debian/: + Drop inert file (due to wrong file suffix): debian/x2goserver.link. + Drop x2goserver-xsession.links. Symlinking provided by main Makefile's install target. * debian/x2goserver.postinst: + When testing for existence of /etc/x2go/applications, also consider it being a dangling symlink (dangling symlinks are not caught by 'test -e', but need a 'test -L'. Thanks to Andreas Beckmann for helping with this. (Fixes: DBTS#904515). Backported from a Debian patch. * debian/x2goserver-printing.postrm: + Remove x2goprint's spool dir on purgal. * debian/x2goserver-common.postrm: + Properly purge /etc/x2go and /var/lib/x2go. . [ Mihai Moldovan ] * New upstream version (4.1.0.1): - Makefile.PL: adjust embedded version number. - x2goserver/lib/x2gocheckport: remove executable flag. This file is not meant to be executed directly, but rather sourced by other X2Go shell scripts. - x2goserver-x2goagent/Makefile: do not stage rgb file any longer. Obsoleted, is now hardcoded into nxagent directly. - x2goserver-x2goagent/etc: remove rgb file. - x2goserver-fmbindings/Makefile: install share/mime/packages/sshfs-x2go.xml as a plain file, not an executable. - x2goserver-x2goagent/share/x2go/x2gofeature.d/x2goserver-x2goagent*: make executable. - x2goserver-x2goagent/Makefile: replace ${PREFIX}/bin/x2goagent wrapper script with a symlink to the ... x2goagent symlink in the NXLIBDIR. - x2goserver-x2goagent/bin: remove x2goagent wrapper script. Unneeded and actually harmful nowadays. - x2goserver-x2goagent/bin: add .keep file to keep this directory around. - x2goserver-x2goagent/Makefile: it's $(NXLIBDIR), not $(NX_LIBDIR). - x2goserver-x2goagent/Makefile: add missing bin component in symlink target for ${PREFIX}/bin/x2goagent. - x2goserver-common/Makefile: stage tmpfiles.d config file into ${PREFIX}/lib/. File should not be modified by users. - x2goserver-common/: move etc/tmpfiles.d to lib/tmpfiles.d. - x2goserver/sbin/x2godbadmin: whitespace only. - x2goserver/sbin/x2godbadmin: use global variable instead of hardcoded string (since the global variable is used latter on anyway). - X2Go/Server/DB.pm: add high-level MySQL/MariaDB support. References the X2Go::Server::DB::MySQL module (and functions/subroutines in there) which currently does not yet exist. - x2goserver/sbin/x2godbadmin: wrap PostgreSQL code in own block, should not have any functional impact. - {X2Go/Server/DB/PostgreSQL.pm,x2goserver/sbin/x2godbadmin}: move /etc/x2go/x2gosql/passwords/x2goadmin or ${HOME}/.x2go/sqlpass to .../x2gopgadmin and .../pgsqlpass respectively. Move is done at run-time, so no user interaction should be required. It requires one database operation to be carried out first in order to trigger the move, but x2godbadmin does not actually use that account information (only generates it), so we should be in the clear. - x2goserver/sbin/x2godbadmin: generate more secure user-level database passwords. - x2goserver/sbin/x2godbadmin: split out subroutines into main namespace, call them generically with correct parameters from specialized namespace. - x2goserver/sbin/x2godbadmin: remove potentially confusing whitespace. - x2goserver/sbin/x2godbadmin: fix up other try blocks; whitespace only. - x2goserver/sbin/x2godbadmin: implement MySQL support, based on Walid Moghrabis changes, but slightly amended. Caveat: INCOMPATIBLE DATABASE SCHEMA! - x2goserver/sbin/x2godbadmin: update copyright header. - UNINSTALL: add reference to remove mysqladmin password file if uninstalling the tarball manually. - x2goserver/sbin/x2godbadmin: no need to specify or use database for list_users operation. - X2Go/Server/DB/PostgreSQL.pm: fix syntax error. - x2goserver/sbin/x2godbadmin: don't use prototypes when functions actually take arguments. - X2Go/Server/DB: add new file MySQL.pm, implementing the MySQL session storage backend. Based on original code by Walid Moghrabi, but modified. Will fail to execute correctly, so do not use yet. - X2Go/Server/DB/MySQL.pm: copy over some (modified) functions and use them for validating session IDs, check user names at some places and the like, which will come in handy at a later point. - x2goserver/sbin/x2godbadmin: whitespace-only change. - X2Go/Server/DB/MySQL.pm: move into new X2Go_in_progress_do_not_use top-level directory. - x2goserver/sbin/x2godbadmin: error out when encountering MySQL server config for now. - X2Go/Server/DB.pm: error out when encountering MySQL server config for now. - x2goserver-common/etc/x2gosql/sql: add example MySQL section and add to "supported" backends list. - x2goserver-common/etc/x2gosql/sql: reformat PostgreSQL comments. - X2Go/Server/DB.pm: don't use X2Go::Server::DB::MySQL for now. - X2Go/Server/DB.pm: comment out calls to X2Go::Server::DB::MySQL::*. - x2goserver-x2goagent/etc/x2goagent.options: typo fix in comment only. - x2goserver-x2goagent/etc/x2goagent.options: disable BIG-REQUESTS; leads to a lot of weird crashes and is currently not implemented correctly in nxagent. Fixes: #1266. - x2goserver/bin/x2gostartagent: fix calculation syntax errors, drop useless subshells, don't use -o operator in plain test calls. - x2goserver-printing/bin/x2goprint: work around atomicity problems with newer FUSE versions, create .ready file as .notready, move/copy to target file system and only then rename it in a hopefully atomic fashion. - *.{8,5}: pre-release date update. * debian/{control,compat}: + Bump DH compat level to 9. * debian/: + Rename config to x2goserver.config. + Remove obsolete x2goserver-{extensions,printing,xsession}.dirs files, should be correctly handled via the main Makefile and staging by *.install files. + Remove obsolete x2goserver-fmbindings.dirs file. + Rename x2goserver.dirs to x2goserver-common.dirs, moving /var/lib/x2go to the -common package. + New file x2goserver-printing.dirs: own /var/spool/x2goprint. * debian/x2goserver-x2goagent.install: + Do not install rgb file/symlink any longer. * x2goserver.spec: + Do not install rgb file/symlink any longer. + Bump nxagent requirement to 3.5.99.5+. + Remove stale symlinks check workaround now that we pull in nxagent >= 3.5.99.0 by default. + Move references from etc/tmpfiles.d to %{_prefix}/lib/tmpfiles.d. + Depend upon perl(DBD::mysql) for MySQL/MariaDB support in perl DBD. + Comment out perl(DBD::mysql) dependency for now. + Backport dangling symlink check for /etc/x2go/applications. + Pull in GCC as a build dependency. + Mask out variables in comments to avoid build-time warning messages. + Work around build failure on Fedora Rawhide/29+ by pulling annobin in explicitly. Shouldn't be necessary, but the current architecture around redhat-rpm-config requires that. * debian/copyright.in: + Remove reference to rgb file. + Remove reference to x2goagent wrapper script. + Add .keep file in x2goserver-x2goagent/bin directory. + Change reference from x2goserver-common/etc/tmpfiles.d to x2goserver-common/lib/tmpfiles.d. * debian/x2goserver.dirs: + Remove etc/x2go/x2gosql references, already handled by x2goserver-common. + Remove all other obsolete entries that should be handled by the main Makefile and x2goserver.install staging. * debian/control: + Bump versioned dependency upon nxagent for x2goserver-x2goagent to the first version that hardcoded the RGB file into nxagent. + Pre-Depend on new enough dpkg for the dpkg-maintscript-helper to be available. + Change http to https links. + Pull in other changes from Debian downstream. + Depend upon libdbd-mysql-perl for MySQL/MariaDB support in perl DBD. + Deactivate libdbd-mysql-perl dependency for now, but keep as comment. * debian/x2goserver-x2goagent.{{pre,post}inst,postrm}: + Handle /etc/x2go/rgb conffile removal gracefully. * debian/x2goserver*{pre,post}*: + Rework scriptlets, use updated templates, add missing templates, more and better quoting, fix other misc. errors within the scripts. * debian/rules: + Enable hardening and automatic passing of *FLAGS. * debian/x2goserver-xsession.lintian-overrides: + Whitespace/EOL change only. * debian/*.manpages: + Prepend paths with debian/tmp/ in order to work around pre-compat-11 levels not falling back to looking into debian/tmp/ for files. * debian/x2goserver.{install,manpages}: + Also install x2goumount_* symlinks. * debian/x2goserver-common.install: + Move etc/tmpfiles.d entry to usr/lib/tmpfiles.d. * debian/x2goserver-x2goagent.{{pre,post}inst,postrm}: + Handle /etc/tmpfiles.d/x2goserver.conf conffile (re-)move to /usr/lib/tmpfiles.d/ gracefully. * debian/libx2go-server-db-perl.post{inst,rm}: + Add support for mysqladmin password file. * debian/{libx2go-server-db-perl,x2goserver{,-common}}.postrm: + Do not try to run rmdir on /etc/x2go if it doesn't exist.
