Bug#1134: Bug#1134: No environment variable available for testing in .bash_profile or .bashrc
by Ted Toal 11 Jan '17

11 Jan '17

First, I’m checking DISPLAY by these methods: env | grep DISPLAY echo $DISPLAY By xterm in single application mode, do you mean to start a terminal window from XQuartz? Or do you mean to start an application from x2go using published applications mode? Or? When I ssh into the machine from Mac Terminal or from a terminal window in XQuartz, DISPLAY does not have a value. I don’t know much about the different window environments for unix, but when I set TRINITY on x2go, I am unable to connect, I get the error “Unable to execute: start trinity”. I’m new at x2go and haven’t read any manual yet, I’m just trying to go for it. ted > On Jan 10, 2017, at 2:55 PM, Stefan Baur <X2Go-ML-1(a)baur-itcs.de> wrote: > > Am 10.01.2017 um 23:44 schrieb Ted Toal: >> I’m running in windowed mode (XFCE) through x2go and XQuartz.

Bug#1133: Inconsistent Perl used by server or its agent on connect
by Ted Toal 11 Jan '17

11 Jan '17

Package: NXAGENT Version: 3.5.0 My .bash_profile defines Perl environment variables for Active Perl, and adds the Active Perl bin directory to the start of the path. This causes an x2go session to fail with the message: Connection failed. /usr/bin/perl: symbol lookup error: /share/carvajal-archive/PACKAGES/local/ActivePerl-5.24/lib/auto/Sys/Hostname/Hostname.so: undefined symbol: Perl_xs_handshake NXAGENT is user /usr/bin/perl and ignoring the Perl bin directory at the start of the path, but it is nevertheless using the Perl environment variables and so is looking in the wrong place for the Perl library.

Bug#1134: No environment variable available for testing in .bash_profile or .bashrc
by Ted Toal 10 Jan '17

10 Jan '17

Package: NXAGENT Version: 3.5.0 I would like to bypass setting of certain environment variables in .bash_profile if I’m connecting via x2go, but it appears there are no environment variables I can test in .bash_profile to determine if this is an x2go session. After the session starts, some x2go environment variables are there, but not while .bash_profile is executing.

Bug#1131: x2gosqlitewrapper - Session not opening when username starts with a number
by Frank Knoben 09 Jan '17

09 Jan '17

Package: x2gosqlitewrapper Version: 4.0.1.20-3.4 When a username starts with a number, the session on the client computer will not open, after connecting to the server. The problem lies within x2gosqlitewrapper.pl in the sanitizer function. This function will return 0 in the $type eq "x2gosid" case, when the username starts with a number. My workaround is to add a 0-9 in the line number 67 of x2gosqlitewrapper.pl diff x2gosqlitewrapper.pl x2gosqlitewrapper.pl.original 67c67 < if ($string =~ /^([a-zA-Z0-9\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) { --- > if ($string =~ /^([a-zA-Z\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) { elsif ($type eq "x2gosid") { $string =~ s/[^a-zA-Z0-9\_\-\$\.\@]//g; if ($string =~ /^([a-zA-Z0-9\_\-\$\.\@]*)$/) { $string = $1; - if ($string =~ /^([a-zA-Z\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) { + if ($string =~ /^([a-zA-Z0-9\_][a-zA-Z0-9\_\-\.\@]{0,47}[\$]?)\-([\d]{2,4})\-([\d]{9,12})\_[a-zA-Z0-9\_\-\.]*\_dp[\d]{1,2}$/) { if ((length($1) > 0) and (length($1) < 48)){ return $string; } else {return 0;} } else {return 0;} } else {return 0;} } I am using a OpenSuSE Leap System with x2goserver Version 4.0.1.20-3.4 Sincerly Frank Knoben

Bug#1126: x2go session disconnects causing an issue with a program or caused by an issue with a program
by Ulrich Langenbach 04 Jan '17

04 Jan '17

Package: x2goclient Version: 4.0.5.2-0~1205~ubuntu14.04.1 severity: critical The session disconnects at some 'arbitrary' point in a way. Today I hit the issue whilest running the client in debug mode: x2goclient --debug and got this message (line 119 in the attached log): x2go-DEBUG-../src/onmainwindow.cpp:6014> Proxy wrote on stderr: "Error: Can't add a message of 4143380232 bytes to write buffer. Error: Assuming error handling data in context [B]. Session: Terminating session at 'Sun Dec 18 18:48:08 2016'. One of the instances of the program run within the remote session stopped working with an internal error. Sometimes the session crashes completely so that also the servers X session is gone, although that might be a different issue. I run an up-to-date Ubuntu 14.04.5 LTS (kernel 3.13.0-105-generic, libc 2.19-0ubuntu6.9) and X2Go Client 4.0.5.2 installed via http://ppa.launchpad.net/x2go/stable/ubuntu. This is really annoying, especially as this may ruin some hours of work and/or compute. The bug seems to be only triggered by one of our most used EDA tools, Vivado, especially in its version 2016.2. As this issue is probably complicated to reproduce, find and fix, a workaround is also very appreciated. Thank you very much! Ulrich

Bug#1130: Arctica-NX-Libs Betatest fails with Ubuntu 14.04
by Walid MOGHRABI 04 Jan '17

04 Jan '17

package: nx-libs Hi, following the instructions from http://wiki.x2go.org/doku.php/doc:howto:nx-libs-betatesting, but using Ubuntu 14.04 and manually adding the MATE PPA for 14.04, I encountered the following error message as a popup from X2GoClient when trying to connect: "The remote proxy closed the connection while negotiating the session. This may be due to the wrong authentication credentials passed to the server." In /var/log/auth.log on the server, I get this error: Jan 4 15:54:39 test2 sshd[3431]: Accepted publickey for walid from 10.8.0.6 port 45976 ssh2: RSA 82:fd:9b:f0:24:b3:95:25:2e:c5:f1:85:ae:e5:8f:1a Jan 4 15:54:39 test2 sshd[3431]: pam_unix(sshd:session): session opened for user walid by (uid=0) Jan 4 15:54:39 test2 sshd[3431]: pam_systemd(sshd:session): Failed to create session: No such file or directory Jan 4 15:54:42 test2 sshd[3454]: error: connect_to localhost port 54731: failed.
