ATTN: Alex - Questions regarding x2goclient.exe --portable and session specification
by newsgroups.mail2＠stefanbaur.de 17 Feb '12

17 Feb '12

Hi Alex, I noticed that x2goclient.exe can be called with --portable to make it use a session file rather than Windows registry entries. Is it possible to specify the location of the session file? Is there a way to export/import sessions from the registry to a sessions file and back? Is there any kind of documentation as to which command line options are available *specifically with the Windows x2go client*? By the way, the message that is shown after "x2goclient.exe --help" is too large to fit on my screen. It doesn't have scroll bars, and there's no way to resize that window, either. I have to use Ctrl-A, Ctrl-C to copy the message to the clipboard, then hit space to "click" the OK button that is outside of my screen, then paste the clipboard content into a text editor if I want to read all of it... Also, is it possible to connect without a session file/registry entry, by specifying all required parameters on the command line? if so, what are the minimum required parameters for that? Whenever I try to pass parameters, x2goclient.exe simply returns me to the command line. :-( The only parameters that seem to cause a response are "--help", "--maximize" and "--hide"... -Stefan

x2goagent listening on public interface - how to make it listen on 127.0.0.1 only?
by BUGHUNTER 16 Feb '12

16 Feb '12

Hi, unfortunately on x2go-users nobody was able to answer this question, maybe here is anybody who knows how to fix this: I am testing x2go - looks like a very good alternative to other solutions! However, I see that (only) when I am logged in via x2goclient I have an x2goagent process listening on the server on all network interfaces on port 6050 - I would feel better if this software did only listen on 127.0.0.1, if this is technically possible. I did not found any hint on a "listen 127.0.0.1" configuration item and where to put it, if existing - how can I make x2goagent NOT listen on a public network interface? Thanks for your attention, Bughunter

Packaging nx-libs (aka x2goagent) for your distro
by Mike Gabriel 16 Feb '12

16 Feb '12

Hi Oliver, Milan, Please build x2goagent from nx-libs.git. Tarballs are available here: http://code.x2go.org/releases/source/nx-libs the symlink... -------------- nx-libs aims at being a replacement for nxagent (as being used with FreeNX, for example) whilst also providing our x2goagent. x2goagent is nothing more than a branded nxagent. Originally, Alex forked NX libs and nxagent for achieving the branding. However, we recently patched some code into original NX code that makes it now possible for nxagent to recognize under what name the agent is launched. If that name is x2goagent the X2Go branding is turned on, otherwise no branding. the wrapper script... --------------------- nx-libs ships with its own X11 library files (libnx-x11, we call the package for Debian). With your distro's X libraries nxagent/x2goagent will probably fail to run or it will at least be really unstable. You have to install NX libs to some non-default library path (e.g. /usr/lib/nx) and make sure that nxagent/x2goagent finds only those (by tweaking LD_LIBRARY_PATH) and _not_ the distro's X11 libs. Hope that helps!

Hi Terje, cross-posting to x2go-dev as not so many people are listening to x2go-i18n, yet.

From my point of view, I would rather make it easy to run the application in English for debugging and recommend this as the way to go. On Linux, this is easy: LANG=C x2goclient LANG=C pyhoca-gui On Windows, pyhoca-gui has a --lang <LANG> option. About x2goclient, I do not have a clue. Doing error number bookkeeping, I guess I won't become a fan of...

I guess we should not change anything here, unless we find a way to offer both possibilities: suspend+resume -> freeze a session state and unfreeze it later disconnect+reconnect -> leave a session running, come back to it later I am wondering if the freeze/unfreeze couple is still available with NX!!! If so, that would be an interesting feature.

Hello developers, One of our clients, Andries Noback, had the following problem, today, with our application, while using x2go. The font size in the application decreased while the connection was established through x2go. This problem ceased to exist, once connecting with goglobal though. In case of question, please refer to our client in the cc-ed e-mail adress. cheers, Besma !DSPAM:4f3cd03e15821821912512!

connection fails with - Access denied. Authentication that can continue: publickey, keyboard-interactive
by brian mullan 16 Feb '12

16 Feb '12

Using Ubuntu 11.10 64bit for x2goserver Installed everything as usual >From my client (also Ubuntu 11.10 64 bit)... I try to connect and get the message about accepting a server connection not seen before and I answer - yes. I then get the x2goclient window to provide my password and I do so. It comes back immediately with this message? Access denied. Authentication that can continue: publickey,keyboard-interactive I've not seen that before but anyone got an idea what's causing it? sshd_config on the server is configured to allow password logins Brian

Re: [X2Go-Dev] [x2go-i18n] Norwegian x2goclient translation

Hi Terje, thanks for your contribution and your willingness to help continuously in the future.

Great, this is a good place to attache those files for now.

BTW: your .ts file has been committed. http://code.x2go.org/gitweb?p=x2goclient.git;a=commitdiff;h=373da1c16fb5cad… Unfortunately, Qt4 seems to lack Bokmal support. So not all elements/widgets of x2goclient will be translated. Test packages are currently building for Debian, Ubuntu package will follow within the next 24 hours. Please install x2goclient from the nightly build repos you prefer for your OS/Distro.

Session Crash
by Andrew Mason 14 Feb '12

14 Feb '12

Hi All, I know the session crashing issue on debian has been a work in progress for a while now. I was just wondering if any of releases in the non-stable PPA / repo were less likely to crash? I understand this is difficult and I don't have any expectations of it being fixed it a fixed amount of time. I just havne't had time to follow the mailing list every day so I'm not sure what the current state is. Thank you for the great software. Andrew
