Bug#799: x2golistdesktops - ss options
by Orion Poplawski 10 Nov '16

10 Nov '16

So, it appears to be well known that 'ss -lxu' has been broken on some systems and returns nothing. This is currently true on EL 7.2 though appears fixed in 7.3 beta. However, why is -u being passed to ss in the first place? We're doing: my $lines=system_capture_stdout_output("ss", "-lxu"); my @lines=split("\n", "$lines"); my @outp = grep ( /(@| )\/tmp\/.X11-unix\/X.*/, @lines); for(my $i=0;$i<@outp;$i++) { ... so we're filtering the output of ss for lines that look like unix sockets (/tmp/.X11-unix/X*), so -lx is appropriate. But why use '-u' to show UDP sockets? No X server that I know of listens on UDP and we certainly would filter it out anyway. diff --git a/x2goserver/bin/x2golistdesktops b/x2goserver/bin/x2golistdesktops index 386ed17..1cbc7ef 100755 --- a/x2goserver/bin/x2golistdesktops +++ b/x2goserver/bin/x2golistdesktops @@ -66,7 +66,7 @@ my $uname=$ENV{'USER'}; # -> so we need to tweak the PATH env var a little here... my $old_PATH=$ENV{'PATH'}; $ENV{'PATH'}="$ENV{'PATH'}:/usr/sbin:/sbin"; -my $lines=system_capture_stdout_output("ss", "-lxu"); +my $lines=system_capture_stdout_output("ss", "-lx"); $ENV{'PATH'}=$old_PATH; undef $old_PATH; See also https://bugzilla.redhat.com/show_bug.cgi?id=1371690 -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA/CoRA Division FAX: 303-415-9702 3380 Mitchell Lane orion(a)cora.nwra.com Boulder, CO 80301 http://www.cora.nwra.com

Bug#1093: x2goclient on OS X not finding MacPorts xmodmap executable in /opt/local/bin then crashes
by Arthur J 10 Nov '16

10 Nov '16

Package: x2goclient Version: X2Go Client v. 4.0.5.2 (Qt - 4.8.7) Operating System: OS X El Capitan version 10.11.6 Tags: macos osx x2goclient xmodmap path I have installed the latest x2goclient package on OS X El Capitan using MacPorts. I have also installed the MacPorts xorg-server and xmodmap packages. In my user account .profile script, MacPorts has added the following line to set the PATH variable: export PATH="/opt/local/bin:/opt/local/sbin:$PATH" I have confirmed that xmodmap exists in one of these directories, in: /opt/local/bin When attempting to connect to any X2Go session, an error dialog appears with the following message before the application crashes: xmodmap failed to start. This likely means the binary is not available. The current search path is: /usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin X2Go Client will now terminate. It appears that /opt/local/bin is not being searched for xmodmap, despite its presence in the PATH variable of my user account .profile script. I even attempted to reboot before starting x2goclient in case the PATH variable needed to be re-read, but the error did not change. This is preventing me from using the OS X x2goclient application.

Bug#1091: 'Xset: Unable to open display' prevents connection
by Sandro 10 Nov '16

10 Nov '16

Package: x2goserver Version: 4.0.1.19 I have a Linux Mint 18 x2go client and a Debian Testing x2go server. And I update both at random intervals. Things just worked for ages. I think I went from Linux Mint 15 to 18. Debian is also really uptodate. Then at one moment - I don't exactly know when because I don't use x2go daily - I started getting this error message. Connection failed. xset: unable to open display "" http://i.imgur.com/Z6yQb4R.png This sounds like one of those xorg errors you get when doing x stuff while not logged into a virtual terminal, but in the case of x2go, I use the magic but don't know how it works, so I have no idea where to start looking. Client machine: Linux Mint 18 (AKA Ubuntu 16.04) x2goclient 4.0.5.1-1 pyhoca-gui 0.5.0.4-1* pyhoca-cli 0.5.0.2-1* Server: Debian Testing x2go-server 4.0.1.19-0x2go2+git20160621.1064+stretch.main.1 x2goserver-xsession 4.0.1.19-0x2go2+git20160621.1064+stretch.main.1 nxagent 2:3.5.0.32-0x2go1+git20160614.734+stretch.main.1 *) Never heard of there. I don't think I ever installed them. I figured I didn't have them installed before so I installed them now. Didn't fix my problem though.

Upcoming Deprecation of EOL Distributions
by Mihai Moldovan 03 Nov '16

03 Nov '16

Hi In order to lower resource stress when building packages, I plan to deprecate support for distributions that have reached End Of Life on September 4th 2016. This includes the following distro versions: - Debian: o 6.0 "squeeze" - Fedora o 19 o 20 o 21 o 22 - OpenSuSE o 12.2 o 12.3 o 13.1 - SuSE Linux Enterprise Desktop (not Server!) o 11.2 o 11.3 After deprecation, no new builds will be published and existing builds will be deleted from the repositories to discourage users from installing unmaintained software.

by Jabiertxo Arraiza Cenoz 23 Oct '16

23 Oct '16

Package: x2goclient Version: 4.0.5.3 In two Debian stretch computer with all x2go versions -debian, x2go and x2go nigtly- when try to open a menu in a GTK3 program, the menu dont show. Usualy you get a thin line on top right corner with a width of the menu. Also sometimes in the same position the line is a bit biger and show one item of the menu. GTK2 menus work well. Tested in diferent desktops, console... Cheers, Jabier.

Package: x2goclient Version: 4.0.5.3 Hi, x2go has a impresibe list of quality conexions, but seems dificult to select to not advanced user forcint try/get some times and finaly select one maybe not best suited to your conexion, maybe we can tag it with the recomended conexion -LAN,ADSL,T1...- or with the level of quality.

Package: x2go-client Version: 4.0.5.2 With win 7 and a first fresh install of x2go client I could not get client-side printing nor folder sharing activated . THe message popped up after attempting connection that sshd has not been started due to problem loading host key. the log : Could not load host key: /cygdrive/C/Users/user/.x2go/etc/ssh_host_dsa_key Disabling protocol version 2. Could not load host key sshd: no hostkeys available -- exiting. I run the key gen that is provided with the x2go client package manually but kept getting the same error I listed the content of the direcotry mentioned above Directory of c:\Users\user\.x2go\etc 2016-10-20 22:53 <DIR> . 2016-10-20 22:53 <DIR> .. 2016-10-22 22:38 279 sshd_config 2016-10-20 22:53 1 679 ssh_host_rsa_key 2016-10-20 22:53 405 ssh_host_rsa_key.pub and realised that the file name contains _rsa_ not _dsa_ as x2go client expects I created copy of the files but renaming _rsa_ to _dsa_ and it works - both the client side printing as well as direcotry sharing Client OS version: WIN7 x2go version : latest september 2016 build
