X2goServer successfully connects to server, but no window is shown
by Iuri Sampaio 06 Feb '19

06 Feb '19

Hi there, After installing X2GO server, in a Debian/LXDE server, I tried to connect to it but the next window, within the console doesn’t show up, I found this discussion in the Forum, but even after installing nx-libs and x2go agent, the problem still remains. https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=516 The status says Finished, the console icon appears in the menu, but the console window just doesn’t come up. Then, if I tried once more, the Status box shows the last connection, in order to resume to the last session opened. Thus, it seems that the connection went through, but there is something missing in the server side to deliver console display. What package/library should be missing. p.s. logs show no errors so far. tail -f /var/log/messages | grep x2go Best wishes, I

Furthermore, in attempt to install x2gobroker, it returns errors because "python3-wsgilog" library doesn’t exist. What would be its substitute in Debian/LXDE? ~# apt-get install x2golxdebindings x2gobroker Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

Anyone know what would cause a completely black screen on resuming a session? windows 10 client, EL7 server.

Help need with Linux-Linux Kerberos Authentication
by rubens.zanatta＠grad.ufsc.br 25 Jan '19

25 Jan '19

Hello there. We're trying to use X2Go in our campus as a user friendly Linux-Linux remote desktop solution. We would also like a SingleSingOn approach, so we chose to use kerberos authentication between the Linux clients and the X2Go server. We already have a working KDC that authenticates a SSH server, as a test. On the client I have the Kerberos 5 Auth. option checked, but when I attempt the connection, the screen remains blank and never connects. The log shows this socket error but the authentication seems to be working. > x2go-INFO-8> "Starting connection to server: newhost.com:22" > x2go-DEBUG-../src/onmainwindow.cpp:3007> Starting new ssh connection to server:"newhost.com":"22" krbLogin: true > x2go-DEBUG-../src/sshmasterconnection.cpp:175> SshMasterConnection, host "newhost.com"; port 22; user "remoto"; useproxy false; proxyserver ""; proxyport 22 > x2go-DEBUG-../src/sshmasterconnection.cpp:244> Starting SSH connection with Kerberos authentication. > x2go-DEBUG-../src/sshmasterconnection.cpp:252> SshMasterConnection, instance SshMasterConnection(0x55e041b1c730) created. > x2go-DEBUG-../src/sshmasterconnection.cpp:520> SshMasterConnection, instance SshMasterConnection(0x55e041b1c730) entering thread. > x2go-DEBUG-../src/sshmasterconnection.cpp:834> Session port before config file parse: 22 > x2go-DEBUG-../src/sshmasterconnection.cpp:844> Session port after config file parse: 22 > x2go-DEBUG-../src/sshmasterconnection.cpp:909> Session port before config file parse (part 2): 22 > x2go-DEBUG-../src/sshmasterconnection.cpp:919> Session port after config file parse (part 2): 22 > x2go-DEBUG-../src/sshmasterconnection.cpp:944> cserverAuth > x2go-DEBUG-../src/sshmasterconnection.cpp:985> state: 1 > > x2go-DEBUG-../src/sshmasterconnection.cpp:1633> Starting ssh:"ssh" "-o GSSApiAuthentication=yes -o PasswordAuthentication=no -o PubkeyAuthentication=no -p 22 -l remoto newhost.com bash -l -c 'echo \"X2GODATABEGIN:eb840c04-8bb1-44b2-b29f-e29332c0354e\"; export TERM=\"dumb\"; whoami; echo \"X2GODATAEND:eb840c04-8bb1-44b2-b29f-e29332c0354e\";'" > > x2go-DEBUG-../src/sshmasterconnection.cpp:1661> SSH exited. > x2go-DEBUG-../src/sshmasterconnection.cpp:1662> stdout: "X2GODATABEGIN:eb840c04-8bb1-44b2-b29f-e29332c0354e\nremoto\nX2GODATAEND:eb840c04-8bb1-44b2-b29f-e29332c0354e\n" > > x2go-DEBUG-../src/sshmasterconnection.cpp:1663> stderr: "" > > x2go-DEBUG-../src/sshmasterconnection.cpp:1664> Exit code: 0; status: QProcess::ExitStatus(NormalExit) > > X2GO-DEBUG-../SRC/SSHMASTERCONNECTION.CPP:726> USER AUTHENTICATION OK. > X2GO-DEBUG-../SRC/SSHMASTERCONNECTION.CPP:1727> "SSH_CHANNEL_OPEN_SESSION FAILED": "SOCKET ERROR: DISCONNECTED" > > x2go-DEBUG-../src/sshmasterconnection.cpp:735> Login Check - Failed > x2go-DEBUG-../src/onmainwindow.cpp:3167> Closed SSH Session interaction The documentation on the wiki is blank when it comes to the advanced section and kerberos authentication methods, and I could not find past use cases regarding this approach on the mailing lists (I could've missed it though). Are there any additional configurations needed on the server side or any insights regarding this connection error? Any help towards this setup is appreciated. Regards, Rubens Zanatta

Install x2go TCE-live server

I checked at myself at the test stand as removal of usb drive works After disconnection of usb disk from the thin client Console of the thin client: ls /media/ Data_Treveler After remove usb drive the directory for mount automatically was not removed... We go on the server. We see the link "Data_Treveler" on a desktop and in / home/user/media/rm/Data_Treveler We return to the console of the thin client rm -rf /media/Data_Treveler Now on the thin client there is no Data_Treveler directory On the server in / home/user/media/rm/is empty as well as should be. But the link "Data_Treveler" on a desktop remained. Why I show consideration for it? If during one session the user used many different usb disks, then it will have many not working links on a desktop (garbage) and in / home/media/. It will mislead him... -- С Уважением Строганов Роман

You are right. I use the translator. The description of a problem in my native language is lower При подключении usb диска к тонкому клиенту на нем создается каталог для ее монтирования (например /media/Kingston) Эта же директория пробрасывается на сервер x2go и там доступна. При отключении usb диска каталог монтирования /media/Kingston не удаляется автоматически на тонком клиенте и соответственно он виден на сервере, но пустой. Это вводит в заблуждение пользователей. Я думаю что при отключении usb диска на тонком клиенте должен удаляться каталог монтирования (в нашем случае /media/Kingston), а на сервере удаляться ссылки на флешку с рабочего стола и каталога пользователя -- С Уважением Строганов Роман

Yes, that that went not so. Checksum of my patch was another. I applied yours. Checksum coincided. usb drive are mounted well. Russian is displayed correctly both on the thin client and on the server. To work with objects with the Russian names became possible. Thanks a lot for the help! But me the small mistake seems to eat in a script. After shutdown of usb drive of a directory of assembling are not removed automatically on the thin client and continue to be displayed on the server, but empty. If to insert, for example, 5 usb drive, and the spendthrift to disconnect them, then there will be 5 empty directories. -- С Уважением Строганов Роман

If I carry out ./x2gousbpatch && ./x2gobuild2 2>&1 | tee logfile that the patch is downloaded with github. This is not what it is necessary for me. I change in ./patch/includes.chroot/usr/lib/x2go/tce/x2gousbmount a line elsif (system("mount -tvfat $dev /media/$name/$ldev -o uid=$user,sync,uni_xlate") == 0) on elsif (system("mount -tvfat $dev /media/$name/$ldev -o uid=$user,sync,utf8") == 0) also I carry out ./x2gobuild2 2>&1 | tee logfile create a new build It breaks autoconnection of any disks (ntfs, fat) Not forwarding to server. Does not mount on the thin client. In the console of the thin client I do mount/dev/far32_drive /mnt/fat32 without additional parameters and well I see directories and files with the Russian names. On regular Ubuntu checked connection of usb drive fat32. Everything is well read/written user@3S-13:~$ mount | grep fat /dev/sdb1 on /media/user/ROSTMA type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2) -- С Уважением Строганов Роман

X2go on Salix
by Robert Dinse 22 Jan '19

I installed x2goserver on salix. It complained about a couple of missing perl modules when I tried to login, I installed them, after that it just hangs when I try to login, never times out, never starts up.

I will share the observations: I have 2 identical usb drive. One ntfs, other fat32. On both I create a directory "Новая папка" (new folder) and "новый файл.txt" (new file.txt) We connect both and we watch contents after mount in the console of the thin client: ls /media/ntfs_drive/ Новая Папка новый файл.txt System Volume Information ls /media/fat32_drive/ :041d:043e:0432:0430:044f :043f:0430:043f:043a:0430 :043d:043e:0432:044b:0439 :0444:0430:0439:043b.txt System Volume Information Later we go on the server. We open on the ntfs_drive server and we see normal Russian names of the file and a directory. It is possible to create new objects with the Russian names without problems. Checked even the Ukrainian alphabet. Everything is OK! We open on the fat32_drive server. There is a directory": 041d: 043e: 0432:0430:044f: 043f: 0430:043f: 043a: 0430" and file": 043d: 043e: 0432:044b: 0439: 0444:0430:0439:043b.txt". It is impossible to create directories/files in Russian sshfs transfers such names of files/directories with what them defined when mount... To exclude randomness checked several times -- С Уважением Строганов Роман
