X2go -. shorter nano release cycles
by Mike Gabriel 04 Oct '11

04 Oct '11

hi devs, last week Alex and I talked about shorter nano release cycles and thus shorter cycles of declaring code as stable. Currently, there is no automation and mostly I urge ourselves to declare code as stable. Some projects are actually releasable but do not get released as they get forgotten (e.g. the PXE project x2gothinclient.git). What Alex and I came up with and what I would like to shorly discuss here is a more automated, but still humanly triggered mechanism. The version number of Git projects in X2go Git that (a) are usable (b) are not obviously broken/buggy/instable (c) have not been worked on for 2 weeks (d) have been tested (at least by me and somebody else) will get incremented in the last digit (1.2.3.x -> 1.2.3.y) after these two weeks, packages will be declared as stable and provided in the corresponding repositories. The shorter release intervals will allow us to keep a better track of the milestones within the projects we have made. I partly consider this as a facility of documentation (that is: documenting usable states of the code). Discussion+feedback welcome, Mike PS: The first release day can already be tomorrow: x2gothinclient x2goclient cups-x2go A week from tomorrow: x2goserver x2gognomebindings x2golxdebindings x2goagent (bug fix release currently being prepared by Alex) nxcomp nxcompext nxcompshad nxproxy -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

x2go portable configuration file (a la .nxs)
by Denis Cardon 03 Oct '11

03 Oct '11

Hi everyone, I've been trying to create a "portable" x2go configuration file in order to send it by mail to a remote user (as one would do with a nxclient .nxs configuration file), but I have not been able to get do it (and asking our dear friend google didn't helped either). Could anyone point me in the right direction? cheers, and keep on the good work!

x2godesktopsharing integration into x2goserver
by Mike Gabriel 30 Sep '11

30 Sep '11

Hi all, yesterday I have been working on the C++ code in x2godesktopsharing. To make sure that x2godesktopsharing really gets shutdown on x2goterminate-session, I have added a script to the x2godesktopsharing package that detects the corresponding x2godesktopsharing process for a given session $X2GO_SESSION. This script ,,x2godesktopsharing-terminate" will be exectuted by ,,x2goterminate-session". This brought up the next question: how do we want to handle x2godesktopsharing while a session is suspended. This older versions of X2go (I think) this has been possible. I consider this as a security problem and something that most users do not want. Imagine the scenario: o start x2go session o start x2godesktopsharing o allow user foo to share your desktop and remember this setting permanently (via .x2godesktopsharing/settings) o suspend your session (and x2godesktopsharing continues to offer desktop sharing... :-( ) o user foo tries to connect to your desktop while you are away (while your session is suspended o -> this is YUK! So what I have done is this: o on session suspend, terminate x2godesktopsharing and remember that it was running, place a server-side empty file ,,resume-desktopsharing'' into $HOME/.x2go/C-$X2GO_SESSION/ o on session resume, check if that file is there and if so, launch a new instance of x2godesktopsharing, with sharing mode set to disabled. Feedback, comments? Mike PS: I have just looked at my commits from yesterday and it feels like I should rename the provided scripts in this way: x2godesktopsharing-terminate -> x2goterminate-desktopsharing x2godesktopsharing-suspend -> x2gosuspend-desktopsharing etc. -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

x2goserver goes pluggable
by Mike Gabriel 30 Sep '11

30 Sep '11

Hi all, last night I have implemented a very basic pluggable extension system for x2goserver. The relevant folder structure will be installed by the x2goserver-extensions package. What the package provides is described on the x2goserver-run-extensions man page: http://code.x2go.org/doc/x2goserver-extensions/man/man8/x2goserver-run-exte… Feedback+Comments+Criticism are Welcome!!!

X2go i18n team
by Mike Gabriel 30 Sep '11

30 Sep '11

Hi all, we would like to set up an i18n team for X2go. The task of this team will be the maintenance of translation files in all X2go projects that utilize translation mechanism. Do I need to be able to read and write code for this? Definitely, no! Become a member of a translation team is a possibility to be in close contact to the developer team without necessarily being able to code. Only pre-requisite: you use X2go quite regularly and no the functionalities of the X2go components... plus: your English is good enough to find good translations of menu items, dialog boxes, etc. Each translator is responsible for the translation files of his/her language. Of course, it is also possible to maintain one translation language as a sub-team (that is: one language is maintained by more than one person). Currently these applications are using translation features: x2goclient pyhoca-gui x2gognomebindings plasma-widget-x2go (KDE$ binding) x2godesktopsharing x2goadmincenter ... (possibly more to come) ... The idea is to have a dedicated mailing list for announcing x2go-i18n issues (mostly mails like: ,,i18n Team, please translate this-and-that'' and a permanent team (with fluctuations, if needed, but preferably not so much fluctuation among the team members) that feels responsible and dedicated to providing a multi-lingual X2go environment to the world. The tools that we use for translations are currently versatile. Depending on the team we will find ways to standardize the translation technologies (if the team members are flexible with using different i18n tools, then this may not be needed). So, if you are interested in contributing translations to X2go and join the development realm by this approach, please-please-please subscribe to http://lists.berlios.de/mailman/admin/listinfo/x2go-i18n and ping us developers on that list. Thanks in advance for your time!!!

README.i18n
by Mike Gabriel 29 Sep '11

29 Sep '11

Hi all, my suggestion for starting with the X2go i18n subproject is as follows: o developers will provide a README.i18n file in each relevant project folder of X2go Git, this README will explain the translation mechanisms and files of that very project o translators give feedback on the readability of the docs ;-) o translators start the work and follow the steps in the README.i18n files Till now, there have been not been so many subscription on x2go-i18n, so if you feel called, please subscribe!!! http://lists.berlios.de/mailman/listinfo/x2go-i18n As an example of such a README.i18n, I have provided one for the pyhoca-gui.git project: http://code.x2go.org/gitweb?p=pyhoca-gui.git;a=blob;f=README.i18n;h=56dfce2… Thanks a lot for your contributions!!! Mike PS: We will investigate a translation service, but in my opinion the bugtracker question (which is still open) is far more urgent. PPS: (As a side-note: Currently, Heinz is heavily working on your web presentations: the wiki, the blog, merging homepage into the wiki, hosting, etc. So this part currently has top priority here.) -- DAS-NETZWERKTEAM mike gabriel, dorfstr. 27, 24245 barmissen fon: +49 (4302) 281418, fax: +49 (4302) 281419 GnuPG Key ID 0xB588399B mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

BUGS: x2godesktopsharing
by Mike Gabriel 28 Sep '11

28 Sep '11

Hi Alex, today I have implemented basic X2go desktop sharing client support in Python X2go. The commit I already uploaded to X2go Git is very basic and needs quite some fine-tuning and testing before I will weave it into PyHoca-GUI. However, with pyhoca-cli it is already possible to test the desktop sharing client code in Python X2go. While working on that I have encountered two problems, though: 1. When the x2godesktopsharing tray applet gets killed by SIGTERM it does neither remove its socket file /tmp/x2godesktopsharing_... nor its lock file... As a consequence, the x2golistdesktops script returns stale desktop sessions resulting from stale x2godesktopsharing lock/socket files. x2godesktopsharing only removes its socket/lock files if the ,,Beenden'' item in the applet's tray menu is clicked. 2. When connecting to x2godesktopsharing the x2godesktopsharing applet always shows wrong username: (a) session already running as user-a, start x2godesktopsharing (b) connect a shadow session to user-a's session (as user-b) (c) user-a then gets asked if it will accept an incoming connection from user-a(!!!!), here it should ask for user-b instead The basic question here is a question of concept. I currently only see this approach: (i) -> pass another parameter from x2gostartagent to x2godesktopsharing (client mode), this parameter will be a representation of the connecting user name (and maybe gecos field?) It would be good to fix both issues some time in the near future. Apart from these two issues x2godesktopsharing works brilliantly. Another cosmetic change could be an improvement of x2godesktopsharing's whitelist/blacklist editor (e.g. add users manually, maybe even add groups manually etc.). But that is rather of a lower priority...
