Package: x2goserver Version: 4.0.1.6 I am experiencing bug #93, which shows "Bug archived" at http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=93 since Mon, 04 Feb 2013 06:24:01 GMT. I am running a Linode virtual private server with a minimal CentOS 6.4 installation. It did not have /tmp/.X11-unix by default. I installed x2goserver via the x2go repo; wget -O /etc/yum.repos.d/x2go.repo http://download.opensuse.org/repositories/X11:/RemoteDesktop:/x2go/RHEL_6/X11:RemoteDesktop:x2go.repo # rpm -qa | grep x2go x2goagent-3.5.0.20-4.1.x86_64 x2goserver-4.0.1.6-1.1.x86_64 X2goclient sessions would hang and the server side message was; # cat clients _XSERVTransmkdir: ERROR: euid != 0,directory /tmp/.X11-unix will not be created. _XSERVTransSocketUNIXCreateListener: mkdir(/tmp/.X11-unix) failed, errno = 2 _XSERVTransMakeAllCOTSServerListeners: failed to create listener for local I had to create /tmp/.X11-unix manually, or log in as the root user via x2goclient to solve the problem. With /tmp/.X11-unix created, the non root user's can now log in with x2goclient running on Windows XP/7 and Debian.
