Shifting my focus in X2Go
by Mike Gabriel 10 Jan '15

10 Jan '15

Dear X2Go Community, dear friends, as many of you may know, I have been contributing a considerable amount of time to upstream-maintaining X2Go over the past 4 years. I provided new X2Go components (Python X2Go, PyHoca X2Go Client, a publicly available X2Go Session Broker, X2Go MATE Bindings, etc.) and focused on making X2Go a wide-spread community project. For the last 2-3 years I have been in the role of the X2Go project coordinator and various other roles. With the beginning of 2015, I will pass on several of those roles to other people in the project, see the below list for already assigned and unassigned roles: o project/community coordinator (continued by Stefan Baur) o development coordination (continued by Heinz-Markus Graesing, very probably introducing some sort of agile development) o release management (n.n.) o i18n team leader (n.n.) o package maintenance (continued by Oleksandr Shneyder) o Git administrator (continued by Mihai Moldovan) o bug tracker administrator (continued by Michael DePaulo) The reasons for tremendously reducing my workload on X2Go are these: o more time for development, less involvement in organizational tasks o more time for paid/contracted work (also in the X2Go context) o spend some of my time on doing Remote Desktop Computing research o be more available to Debian and Ubuntu as a package maintainer o be more available to my family In several internal exchanges we (Heinz, Stefan, Mihai, Mike#2, Oleksandr) have discussed several development workflow changes that are likely to be introduced soon within the X2Go project. I leave it to Stefan and Heinz to introduce these ideas publicly via our new mailing list x2go-project(a)lists.x2go.org [1] So that everyone who is interested can get further involved, please make sure you get subscribed to the new x2go-project ML [1] and join the related discussions there. If you are interested, subscribe to this list now. If any of the not-yet-assigned tasks calls your heart, please contact us via the x2go-project ML. Within the last years, we gathered a considerable amount of very genuine people around the X2Go project. People with high social and technical skills, time for contribution and a clear disposition to make X2Go the best terminal server solution on Linux/*nix available, while maintaining it as FLOSS software in all respects. I highly appreciate what we all have achieved during the last years and am thankful for all discussions, experiences and friendships made. Thanks to everyone who helped us coming this far. Thanks to everyone stepping up and taking over more reponsibility within the project. I will continue working on the following X2Go topics in the future: - X2Go Session Broker (component owner) - Python X2Go / PyHoca-GUI+CLI (component owner) - NX (aka nx-libs, component owner) - Debian/Ubuntu packaging of X2Go (downstream/distro activity) For an interim phase (about 2-3 months), I will continue working on my previous tasks. This is to give time to people for arriving in their new roles, so that everyone can gradually take over and feel comfortable. Of course, I will be available for all sorts of questions and advice in the future, if needed. Apart from the interim phase above, I currently have these open X2Go tasks, which I will finish as soon as possible (hopefully at the end of Jan 2015): - do a release cycle of all X2Go components - fix X2Go Desktop Sharing (cross-user, same user, nearly fixed) light+love Mike Gabriel [1] http://lists.x2go.org/listinfo/x2go-project -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Bug#737: X2GoClient should contain an option to add arbitary ssh port forwardings
by Stefan Baur 10 Jan '15

10 Jan '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 package: x2goclient severity: wishlist It would be cool to have an option inside X2GoClient that allows ssh port forwardings, like PuTTY does. For simplicity (so the session DB doesn't have to be changed), this should be limited to portforwardings from the X2GoClient to the Server - - in SSH-speak, "-L1234:foobar.example.com:1234", but not "-R1234:foobar.example.com:1234". - -Stefan - -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (MingW32) iQEcBAEBAgAGBQJUsPPgAAoJEG7d9BjNvlEZTm4IAK64UUW4tiR3vxJQHQxLKDPg nEqbaonYSXysv+HR2p1o+z9XcJIENZc47haJBET7885x7dqI4uqGFVFzdKo30sM/ C5dMDSX9sx2bwAw1RjUDd+kiHTVoPaUkxenz9ep5GPjf4z7nRkTb++skCtC01Cy6 MVHkzimbe93LmHVCn/jH2YsDzV+ssArX7Gc6ZRO0IV6Bn9UUCKU2PNTJmHH7wo39 4gMYS2XZizHl2jXUc04UwFCv4uHD5hBOpzlfMQyqJZss7WmBdbnSfF1SI3kZhdhp JorPuRj6srPWIq1efmxHVED6Xr5jmR6hMZ2R+2R3fhBmU59TeHsljnNplj7is6Y= =upEX -----END PGP SIGNATURE-----

Bug#738: X2GoClient should make use of an open-source PDF viewer and integrate that, for easier printing support
by Stefan Baur 10 Jan '15

10 Jan '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 package: x2goclient severity: wishlist The current way of client-side printing is rather error-prone (see various complaints on the mailing lists lately), also, it requires the user to be in the fuse group on the server. Which opens the can of worms that the user can now also use the built-in file sharing, which may not be desirable in all circumstances. Therefore, I would like to suggest the following as new method of printing: * x2goclient opens an SSH tunnel: -R<somenumber>:127.0.0.1:<someothernumber> * <somenumber> should start at a number above 1024, obviously, and a mechanism must be in place that determines a free port number, then uses that. * <someothernumber> should also be a number above 1024, starting at a fixed base number and incrementing with each user/session (similar to X2Go session numbers). * on the server, CUPS-X2GO creates a PDF (optionally, compressed using gzip, bzip2 or xz - information about the compression method used could be conveyed in a PJL header comment field) and streams it to socket://127.0.0.1:<someothernumber> I'm assuming the following two steps are a non-issue for Mac OS X and Linux, as CUPS is used natively there, and all we have to do there is connect the two CUPSes via a simple portforwarding. * On Windows, x2goclient pipes the incoming data either directly as a stream, or via a temporary file, to a PDF viewer, which (in the simplest case) is set to automatically print to the default printer * optionally, we could pop up the print dialog, though this will add more complexity * for ease of use, we should either ship SumatraPDF (a free PDF viewer that can be automated via command line options) with x2goclient, just as we currently do with pulseaudio and vcxsrv, or integrate the relevant parts of SumatraPDF directly into x2goclient, if based on the same programming language, and being licensed unter terms compatible with ours. 1) This eliminates the need for having users in the FUSE group to merely print a document, 2) also, if we can get SumatraPDF to accept the bitstream, it would even eliminate the need for a temporary file on the client, 3) lastly, by shipping a PDF viewer/printer, we make it easier for the user by providing a sane default (like we do with vcxsrv - users still can use a different X server if they choose to, but they don't have to download one manually first and worry to get the configuration right).

Bug#735: let authentication become more consistent: always fall-back to username+password logins
by Mike Gabriel 10 Jan '15

10 Jan '15

Package: x2goclient Severity: wishlist For the sake of consistency with ssh-agent based logins or pubkey based logins, GSSAPI should also fallback to username+password login if GSSAPI fails. Currently, it simply reports an error (which is actually nice), but after the error, the GUI should allow giving username and password. The user should not notice a different whether he selects pubkey auth, agent auth or GSSAPI auth (and then experiences a failure)...

Bug#734: ssh-agent gets used although GSSAPI is enabled and agent-auth is disabled
by Mike Gabriel 10 Jan '15

10 Jan '15

Package: x2goclient Version: 4.0.3.1 Severity: important Control: block -1 by 733 I have... autologin=false krblogin=true _plus_ a running ssh-agent, loaded with my private SSH key. The X2Go Server has the public SSH key belonging to the private key loaded into the agent. If the remote server does not support GSSAPIauthentication (set to "no" via sshd_config), then X2Go Client should fall back to username+password (KbdInteractiveAuthentication). At the time of writing this, X2Go Client nonetheless uses the running ssh-agent and performs a PubkeyAuthentication. However, this breaks GSSAPI credentials delegation...
