Bug#1550: X2Go/Server/DB/SQLite3.pm: Reads shadow entry ($pass) but it is never used
by Paul Menzel 02 Jun '21

02 Jun '21

Package: x2goserver Version: 4.1.0.3 Dear X2Go folks, We noticed, that every two seconds our “shadow server” (similar to NIS) gets a request for the shadow line of the x2go user [1]. Tracing this reveals: x2gocleansessio-3593 [112] .... 2334059.441996: sys_clone <-system_call_exception <...>-468193 [120] .... 2334059.538048: sys_clone <-system_call_exception <...>-468194 [128] .... 2334059.539367: sys_clone <-system_call_exception x2golistsession-468193 [120] .... 2334059.542178: sys_clone <-system_call_exception libx2go-server--468196 [136] .... 2334059.656827: tcp_connect <-tcp_v4_connect x2gocleansessio-3593 [112] .... 2334059.695737: sys_clone <-system_call_exception <...>-468197 [128] .... 2334059.793699: sys_clone <-system_call_exception x2gopath-468198 [137] .... 2334059.794604: sys_clone <-system_call_exception x2gogetstatus-468197 [128] .... 2334059.797066: sys_clone <-system_call_exception <...>-468200 [097] .... 2334059.912926: tcp_connect <-tcp_v4_connect /sys/kernel/debug/tracing# ps -fp 3593 UID PID PPID C STIME TTY TIME CMD root 3593 1 0 May06 ? 00:36:27 /usr/bin/perl /usr/sbin/x2gocleansessions and (for example the first `libx2go-server-db-sqlite3-wrapper`) → `/usr/share/perl5/X2Go/Server/DB/SQLite3.pm` contains: my ($uname, $pass, $uid, $pgid, $quota, $comment, $gcos, $homedir, $shell, $expire) = getpwnam($x2gouser); my $dbfile="$homedir/x2go_sessions"; > The getpwnam() function returns a pointer to a structure containing the > broken-out fields of the record in the password database (e.g., the lo‐ > cal password file /etc/passwd, NIS, and LDAP) that matches the username > name. Reading `/usr/share/perl5/X2Go/Server/DB/SQLite3.pm` [2] it looks like, the variable `$pass` is never used? ``` sub init_db { # retrieve home dir of x2gouser my $x2gouser='x2gouser'; my ($uname, $pass, $uid, $pgid, $quota, $comment, $gcos, $homedir, $shell, $expire) = getpwnam($x2gouser); my $dbfile="$homedir/x2go_sessions"; my $dbh=DBI->connect("dbi:SQLite:dbname=$dbfile","","",{sqlite_use_immediate_transaction => 1, AutoCommit => 1, }) or die $_; # on SLE 11.x the sqlite_busy_timeout function does not exist, trying to work around that... if ( $dbh->can('sqlite_busy_timeout') ) { $dbh->sqlite_busy_timeout( 2000 ); } return $dbh; } ``` Kind regards, Paul [1]: https://salsa.debian.org/debian-remote-team/x2goserver/-/blob/master/x2gose… [2]: https://code.x2go.org/gitweb?p=x2goserver.git;a=blob;f=X2Go/Server/DB/SQLit…

Bug#1548: Acknowledgement (Copy & Paste images with x2goserver and x2goserver-x2gokdrive)
by Miguel Quero 26 May '21

26 May '21

Of course, I think my company was starting a project to help the development of some opensource projects. I am from the technical side and I don't have visibility but I have just escalated it in case they tell me something. I don't think it's a big deal, we are a small company, but something will surely help. Best regards.

Bug#1548: Copy & Paste images with x2goserver and x2goserver-x2gokdrive
by Miguel Quero 24 May '21

24 May '21

Package: x2goclient Version: 4.1.2.3 Hi, First of all congratulate you for your great work with x2go. We have been using x2go for years in research and reporting environments. The problem we have is that usually in these environments the copy and paste of images is very common. Currently we overcome this problem with the option to share folders but we would like to make the environment more agile by allowing to copy and paste images from the client to the server. After investigating the options we have found the following: 1) If the connection is made through the new kdrive, the clipboard shares images correctly. For example: * Client side: xclip -selection clip -t image/jpg -i hades.jpeg * X2go Kdrive Server side: a simple ctrl-v on a document opened on the server and the image is copied perfectly. * Problems: The problem is kdrive itself that for example for Spanish language neither accents nor many symbols work: (á ^ ä ç à ...). 2) With normal x2go: * Client side: xclip -selection clip -t image/jpg -i hades.jpeg * SSH normal contextion: The clipboard is shared ok xclip -selection clipboard -t TARGETS -o TARGETS image/jpg * X2go Server side: Nothing appear in clipboard :( Any ideas?

Bug#1547: x2go client does not work on Ubuntu 20.04 LTS
by Dirk Kleinhesselink 18 May '21

18 May '21

Package: x2goclient Version: 4.1.2.2-1 The x2goclient does not start the remote desktop for a client on ubuntu 20.04 LTS. This worked fine on Ubuntu 18.04LTS. The client launch says connecting and after a short pause changes to finished but the remote desktop never appears. I am running Ubuntu 20.04 LTS, the current kernel is: 5.4.0-73-generic I've tried different local desktops - MATE, gnome, tried disabling wayland, always the same result.

x2go client help
by Silvia Luescher Folk 13 May '21

13 May '21

Hi, I am having an issue on a Mac Os 11.3 with the x2go client: The issue is that right after restarting my Computer I have no problem connecting to my remote server. But after I stop that session and restarting it later I get the eternal “connecting" status. The only way to fix this is by restarting my computer. My guess is I have to kill some process, but it is not obvious to me which one. Could you help me troubleshoot this? Thank you, Silvia

Bug#1546: Feature-request: Customizable kerberos ticket cache location
by Florian Oppermann 12 May '21

12 May '21

Package: x2goclient Version: 4.1.2.2 Current situation: Authentication via kerberos puts the credential cache into $HOME/.x2go/C-$sessionId/krb5cc. In our system this is problematic as access to $HOME requires a valid kerberos ticket, i.e. once the ticket expires it can’t be renewed from within the X2Go session because access to the ticket cache is denied. For normal logins, the krb5cc is located at /tmp which prevents this problem. I’d appreciate an option to set the location where to put the ticket cache. I believe the current behaviour comes from src/onmainwindow.cpp:7332 where the location is more or less hard-coded. My suggestion would be to add either a configuration option in the GUI or at least a command line switch to change this location. I’m not familiar enough with the code to provide a patch but I think it should be not too difficult. Thanks for all your great work! :-)

Bug#1545: x2goserver: separate
by Jonathan Kirszling 10 May '21

10 May '21

Package: x2goserver Version: 4.1.0.3 I'm packaging x2goclient and x2goserver for voidlinux distro. Voidlinux doesn't use systemd as init, but runit. We need to be able to write a runit service script for x2gocleansessions. x2gocleansessions forks when it is run. Using --debug doesn't fork but print a lot of informations, catched by the service. Could you separate --no-fork from --debug please ? More details here : https://github.com/void-linux/void-packages/issues/30781 Thanks by advance, Have a nice day.

Bug#1544: x2goclient not connecting [with a provisional fix]
by Andrey Malyshev 07 May '21

07 May '21

Package: x2goclient Version: 4.1.2.2 x2goclient stoppped connecting to a working x2go server after some update of the client on both Linux and Mac boxes. Provisional fix - The offending line is "Port 22" in the localhost section of the ~/.ssh/config file on the client side. Commenting out the line solves the problem on both Linux and Mac boxes. It seems that some parser (no idea if it is the x2goclient's or the nxproxy's one) is doing some strange thing and gets confused, as the error message has nothing to do to the port line. A permanent fix would be appreciated. Below are the relevant part of the output from x2goclient --debug and the content of the ~/.ssh/config file with an offending Port line in the localhost section: x2goclient --debug: x2go-INFO-1> "Starting X2Go Client 4.1.2.2..." ... x2go-DEBUG-../src/onmainwindow.cpp:6142> "Starting NX proxy, command: nxproxy -S nx/nx,options=/home/andrei/.x2go/S-andrei-50-1620380095_stRTERMINAL_dp24/options:50" ... x2go-DEBUG-../src/onmainwindow.cpp:6618> Proxy wrote on stderr: "\nNXPROXY - Version 3.5.99.26\n\n...." ... x2go-DEBUG-../src/sshmasterconnection.cpp:1994> Forwarding parameters: from remote ("localhost":33106) to local ("localhost":60552) x2go-DEBUG-../src/sshmasterconnection.cpp:2028> Temporary session port after config file parse: 22 x2go-DEBUG-../src/sshmasterconnection.cpp:2032> Temporary session host after config file parse: 127.0.0.1 x2go-DEBUG-../src/sshmasterconnection.cpp:2059> New channel forwarded. ... x2go-DEBUG-../src/onmainwindow.cpp:6618> Proxy wrote on stderr: "Loop: PANIC!
