Reason for norootlessexit
by Ulrich Sibiller 02 Mar '15

02 Mar '15

Hello, we are seeing problems with rootless nx sessions, when the user is using a window manager like awesome, openbox or xfce (for users using kde or gnome everythign works fine). nxagent often closes the session after switching workspaces (making the nx windows invisible) because according to nxagent there's no client left (which is wrong). This can be prevented using -norootlessexit. However, I was wondering about the reason for this switch. Did anyone have similar problems and therefore added this switch? Uli

Bug#802: pluma and caja launch successfully
by Michael DePaulo 02 Mar '15

02 Mar '15

I figured I'd try 2 other MATE apps as single applications: pluma (text editor) caja (file manager) They both launch successfully. The X2Go session wouldn't terminate when I X'd out of caja, but that is probably unrelated.

[Bug#798] Use of ssh proxy with x2goplugin
by nicolas husson 26 Feb '15

26 Feb '15

When I'm trying to use the ssh proxy configuration in session file with x2goplugin it seems its not working. Indeed, if you look at the session file in "~/.x2goclient/sessions" which contains all the configuration of the session of x2goclient application you will see all the descriptions of each session. Which looks like this for each session: [20150220100323537] speed=2 pack=16m-jpeg quality=3 fstunnel=true export="/home/user/Bureau/MountDistantX2goPc:1;" iconvto=UTF-8 iconvfrom=ISO8859-1 useiconv=false fullscreen=false multidisp=false display=1 maxdim=false rdpclient=rdesktop directrdpsettings= width=800 height=600 dpi=96 setdpi=true xinerama=false clipboard=both usekbd=true type=auto sound=true soundsystem=pulse startsoundsystem=true soundtunnel=true defsndport=true sndport=4713 print=true name=username icon=:icons/128x128/x2gosession.png host=localhost user=userTest key= rdpport=3389 sshport=2222 autologin=false krblogin=false krbdelegation=false directrdp=false rootless=false published=false applications=WWWBROWSER, MAILCLIENT, OFFICE, TERMINAL command=SHADOW rdpoptions= rdpserver= xdmcpserver=localhost *usesshproxy=true* *sshproxytype=SSH* *sshproxyuser=usernameProxy* *sshproxykeyfile=* *sshproxyhost=123.452.111.124* *sshproxyport=22* *sshproxysamepass=false* *sshproxysameuser=false* *sshproxyautologin=true* *sshproxykrblogin=false* The part which interest me is the bold part. Indeed, it works when i'm using this conf file with x2go client. And when i'm using x2goplugin <http://wiki.x2go.org/doku.php/wiki:advanced:x2goplugin> with this configuration it doesn't work. I take a look at the network traffic and it seems that x2goplugin doesn't look at the bold part (the ssh proxy). This is why I think that x2goplugin doesn't work with ssh proxy. Is someone discover the same thing? or its just a misconfiguration? Thanks for your help. -- Best Regard _________________________________________________________________________ Nicolas HUSSON

Bug#632: X2Go issue (in src:x2goserver) has been marked as closed
by X2Go Release Manager 24 Feb '15

close #632 thanks Hello, we are very hopeful that X2Go issue #632 reported by you has been resolved in the new release (4.0.1.19) of the X2Go source project »src:x2goserver«.

[ Mike Gabriel ] * New upstream version (4.0.1.19): - Use File::Which to detect if sshfs command is available before trying to mount a client-side folder. - Be a bit more tolerant when trying to detect if a desktop icon is to be removed (using regexp, not eq). - Xsession script: Prevent bash failures when sourcing external bash scripts beyond our scope. (Fixes: #632, #675). - x2gogetapps: Support scanning of sub-directories when searching for .desktop files. We allow to dive down one level into subdirs, we on purpose do not recursively dive into the complete subtree. (Fixes: #633). - Make man2html an optional tool. Don't fail if it is missing on the build system (required for openSUSE/SLES builds). - Fix x2goserver-xsession/Makefile on SUSE.

If directoy /usr/share/doc/packages/brp-check-suse is present, the build env is also considered to be a SUSE system. - Trigger Xsession code for SUSE systems (look for /etc/SUSE-brand or /etc/SuSE-release for SUSE system recognition). (Fixes: #671). - x2gosqlitewrapper.c: Fix rpmlint error: no-return-in-nonvoid-function. Return the exitcode of execve(). - Fix gramma in error message (in x2goresume-session). - x2gocleansessions: Call x2gormforward also on terminated sessions. This will make sure that re-assigned ports are really available on new session startup. - x2golistsessions(_root): Only update session state in session DB if x2goagent's state file really exists. This addresses a problem that occurs when x2golistsessions gets called via an x2gobroker-agent. The x2golistsessions script may show session states (--all-servers) of sessions on other servers that have session states files on their remote /tmp dirs. These files are not accessible for that x2golistsessions script and should simply be ignored. (Fixes: #638). - Provide pam_namespace support for has_agent_state_file() function. - Fix missing session list output if state file does not exist on the machine that runs x2golistsessions(_root). - Accept more verbose "DENY" output from x2godesktopsharing. - Make sure that all "su"-to-user-contexts use /bin/sh for wrapping around the executed command (in x2gocleansessions and x2golistsessions_root). - Also enforce /bin/sh as shell in su command in x2goprint. - README.i18n: Add file that explains the translation workflow for this package. Thanks to Mark Pedersen-Cook for drafting this file. - Make SSH agent forwarding work after having reconnected via SSH and having resumed a session. (Fixes: #672). Thanks to Robert Siemer for coming up with that idea. - Fix cross-user X2Go Desktop Sharing after being broken by implementing clipboard mode feature (and probably other code changes). - Document session startup / resumption failures (and their reasons) in server-side log output. - Handle AD domain users gracefully when X2Go is used with SQLite DB backend. (Fixes: #664). - Improve sanitizer, use 'x2gosid' sanitizer for session IDs everywhere. Drop unused 'pnixusername' sanitizer in 4.0.1.x release of X2Go Server. - Allow usernames in session IDs of length 48 chars. - Start sshfs with a timeout of 30 seconds (because it never finishes if something is wrong with the client-side TCP socket). Also remove/unmount mountpoints erroneously registered sshfs mountpoints if sshfs command times out. Furthermore, print errors to STDERR (not STDOUT). (Fixes: #405). - Handle execution of ss command from Perl script x2golistdesktops in a way that not only works on Debian, but also on Fedora et al. (Fixes: #727). - Provide legacy support for old File::Path packages in x2godbadmin. (Fixes: #715). - Fix wrong evocation of x2gosyslog ("error" -> "err"). - Use "undef $dbh" instead of "$dbh->disconnect()". Fixes SQLite3 issues on SLE 11.x. - Only call $dbh->sqlite_busy_timeout() if the $dbh object is capable of that. Works around a too-old DBD::SQLite package on SLE 11.x. - Legacy for applications (and X2Go scripts) that expect $SSH_CLIENT to be set in the X2Go session's environment. (Fixes: #644). - Add man page for x2gogetapps. Weave into that a security / disclaimer message as proposed by Stefan Baur.
