x2goserver + x2goserver-extensions
by Mike Gabriel 31 May '11

31 May '11

Hi all, Heinz, Alex and I have just had the idea to split the x2goserver package up into two parts: o x2goserver: everything that is needed to run with the legacy x2goclient o x2goserver-extensions: scripts, tools etc. that may be needed by other X2go client implementations (e.g. Python X2go) The change is already in Git. The two scripts I posted yesterday to the list have already been moved to the new x2goserver-extensions package. PLEASE NOTE!!! These changes will for now only occur in the nightly builds (Debian/Ubuntu).

x2goserver: x2gosetkeyboard
by Mike Gabriel 30 May '11

30 May '11

Hi devs, for introspection I have added an x2goserver script: x2gosetkeyboard to X2go Git: x2gosetkeyboard script: http://code.x2go.org/gitweb?p=x2goserver.git;a=commitdiff x2gosetkeyboard man page: http://code.x2go.org/gitweb?p=x2goserver.git;a=blob_plain;f=.build_man2html… The script takes a ,,keyboard'' file from $HOME/.x2go/C-$X2GO_SESSION and parses its contents for the identifiers rules, model, layout, variant, options. These options will then be passed on to a setxkbmap call. The keyboard file layout has been adopted from the free NX project. In the free NX project they have patched nxagent to digest this ,,keyboard'' file. If the ,,keyboard'' file lacks presence, nothing happens. I would be grateful if people could take a look and comment on potential problems, security issues etc. I would like to use this script as a post-startup command for python-x2go. If you see anything problematic about this piece of code, please let me know and we try to figure out what solution may be best for all. Thanks+Greets, Mike -- 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…

x2goagent 3.4.0.5 vs. nxagent 3.5.0-1
by Mike Gabriel 30 May '11

30 May '11

Hi Alex, to this mail I have attached a diff between our current x2goagent and the newly released nxagent 3.5.0-1 by NoMachine. Do you think you could take a look at it? Which files of the NX code base have been customized for X2go? The latest nxagent seems to have undergone quite some work, I guess it would be good to provide an updated version with Baikal(?). For someone who knows the x2goagent differences to the old-at-fork-time-version of nxagent, this should not be a big problem. Greets+Thanks, Mike -- 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…

x2goclient/doxygen
by Mike Gabriel 30 May '11

30 May '11

Hi devs, I have re-activated x2goclient's doxygen configuration. Now, doxygen is included in the build process and the C++ documentation of x2goclient ends up in /usr/share/doc/x2goclient/doxygen/html I have also removed old doxygen builds (outdated code documentation) from the Git repository.

x2goserver/x2goclient -> man pages / help with wiki pages
by Mike Gabriel 30 May '11

30 May '11

hi all, I have added man pages for x2goclient and x2goserver: http://code.x2go.org/gitweb?p=x2goclient.git;a=tree;f=.build_man2html/html/… http://code.x2go.org/gitweb?p=x2goserver.git;a=tree;f=.build_man2html/html/… I also started wiki pages for x2goclient (there already was some information for this) and x2goserver. For the x2goclient page maybe there is a volunteer who would like to add some more explanations about how the x2goclient GUI can be configured/used, inform about caveats etc. I guess it is completely fine, to have wiki sub-pages for x2goclient usage. For the x2goclient command line option we should refer to the x2goclient's man page. This actually also needs an update. http://wiki.x2go.org/x2goclient For the x2goserver package the new wiki page can be found here: http://wiki.x2go.org/x2goserver From my point of view this wiki page should be used for describing how X2go (server) actually works. This is quite a task and I guess there are only a few people who have dived into the internas of X2go's session handshake. However, if there is someone out there who also feels like picking up the job, that will be really appreciated!!!

added x2goversion script in x2goserver package
by Mike Gabriel 30 May '11

30 May '11

Hi devs, for supporting a more flexible client concept around X2go I have been thinking about a way of realizing server-client handshaking. Basically, the client-side can benefit from knowing individual versions of server-side installed X2go components. Yesterday, as a manifestations of this thinking process I have added an x2goversion script to the x2goserver package. It basically shows the server-side versions of installed X2go components. For the man page, refer to: http://code.x2go.org/gitweb?p=x2goserver.git;a=blob_plain;f=.build_man2html… These server-side component versions are obtained from /usr/share/x2go/versions/VERSION.<x2go-comp> I have added the respective files for all server-side components in X2go's Git (base dir of each Git project: VERSION.<x2go-comp>): x2goserver, x2gognomebindings, x2gotrinitybindings, x2goplasmoidbindings, x2godesktopsharing, cups-x2go, x2goagent I have omitted the NX packages with this X2go version patch as NX code is actually not our code, so we cannot rely on retrievable version with those code projects for every Linux distribution on the market.

X2go announcement-list and messages from git-admin
by Paul van der Vlis 27 May '11

27 May '11

Hello, >From an announcement list I would expect a low volume list what gives information when a new version arrives or when there are security issues or when there is a congress or something like that. But the x2go announcement list [1] does completely something else, what I see are many change-messages from git-admin: https://lists.berlios.de/pipermail/x2go-announcement/2011-April/thread.html I think it would be better to change the usage of the announcement list and to make it an informative low volume list. Further, I see on the page of the list [1] this text: -------- To post a message to all the list members, send email to x2go-announcement(a)lists.berlios.de. -------- I think that's wrong, because it's a read-only list. With regards, Paul van der Vlis. [1] https://lists.berlios.de/mailman/listinfo/x2go-announcement -- http://www.vandervlis.nl/

iPAD now has X and ssh
by John A. Sullivan III 24 May '11

24 May '11

Hello, all. We've received a number of queries about running X2Go on an iPAD. My understanding to this point is that the absolute fundamentals are missing. However, I was recently sent the following: i-SSH for the iPad comes up well in reviews: Description A full featured SSH and Telnet emulator of VT100, VT102, VT220, ANSI, and xterm terminals integrated with a tunneled VNC client and an X server Customer Reviews Great SSH client by Mikaey0 This is definitely a great SSH client. Everything I use works as I expect it to when connecting to my box at home. Definitely nice to see a working X server for the iPad as well! Amazingly functional by Nick75985 Continues to amaze me with new functionality I discover. Never crashed on me. Incredibly full-featured and useful app. by quantumonion Edit: Wow, TextExpander support just added! If an app could give you goose bumps, iSSH would be that app. Only two suggestions come to mind. 1. TextExpander support (done!) 2. Native Dropbox support for the connection list It's possible to save the connection list to Dropbox with the export to clipboard feature, but it'd be great to offer an option to auto-sync any changes automatically. The above are just nits though. This has become one of those indispensable apps that you'd have to pry my cold dead fingers off of before I'd give it up. Given the above, what would it take to get X2Go to run on an iPAD using i-SSH? Is anyone interested if giving it a run? It's definitely outside of our skill set. Thanks - John
