Bug#1225: x2goclient / pyhoca does not honor ProxyJump in .ssh/config
by Filip Krikava 27 Jul '20

27 Jul '20

Package: x2goclient; Version: 4.1.0.0 Due to the configuration of the university network, I have to first connect to a frontend, then to a node and then to a VM. To make this easy to use, I set ProxyJump in my .ssh/config. This works really well for ssh. However, it does not seem to be recognized by x2go. I have to manually tunnel the ssh port from the VM on my localhost to be able to connect there via x2go. The same is for pyhoca-cli 0.5.0.3.

x2goclient for windows with libssh 0.9.4
by Ulrich Sibiller 27 Jul '20

27 Jul '20

Hi, can anybody please rebuild x2goclient with libssh 0.9.4 for windows? And maybe with libssh 0.8.9. I still cannot use the latest version because of problems as described in bug #1460... Uli

Bug#1489: Windows x2go client ignores ProxyJump
by Carsten Bockelmann 27 Jul '20

27 Jul '20

Package: x2goclient Version: 4.1.2.2-2020.02.13 Similiar to this old bug https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1225 ProxyJump is ignored under windows 10. However, the underlying libssh 0.9.3 now supports ProxyJump and at least in ubuntu 20.04 it works out of the box. This is especially frustrating as host certificates are not supported in libssh which currently blocks any config in x2goclient that directly configures the bastion host as proxy (kex exchange method unsupported).

extend x2gopath
by Ulrich Sibiller 10 Jul '20

10 Jul '20

Hi, I would like to fix the long-standing bug that x2gostartageni sets NX_CLIENT to x2gosuspend-agent, which is simply wrong. I would like to point it to nxdialog, if available. The best way to find out the correnct nxdialog path is probably using x2gopath. But I am not really sure how all that x2gopath stuff is supposed to work. I mean, depending on the distribution, nxdialog might be on different locations. E.g. the nx-libs Makefile(s) install nxdialog to $BINDIR, which is $PREFIX/bin by default. The packager can redefine BINDIR and/or PREFIX. x2gopath does not know about BINDIR, it only knows PREFIX. So how can I determine the BINDIR used during packaging of nxdialog? Can anyone shine a light on this? Uli PS: nx-libs.spec does not build an nxdialog rpm yet, so that's needs to be fixed, too.

x2goClient code refactoring
by Dave Chamberlin-Kidd 07 Jul '20

07 Jul '20

Hi, Whilst digging through the code in the x2goClient I've come across void ONMainWindow::processSessionConfig() in onmainwindow.cpp but I can't see anywhere where this code is called. Commenting it out along with a stack of associated code doesn't seem to have any affect. So my question is, is there something obvious I'm missing? If not I'll root through the code and find any other associated bits, rip them out and submit a patch. Cheers Dave

Bug#1479: Possible typo in two x2gothinclient scripts
by Stefan Baur 25 Jun '20

25 Jun '20

package: x2gothinclient-common version: 1.5.0.2-0x2go2~git20200109.735+10.heuler.1 x2gothinclient/management/share/etc/x2gothinclient_init.d/010_x2gothinclient-fresh-home and x2gothinclient/management/share/etc/x2gothinclient_init.d/005_x2gothinclient-wipe-home contain a check if the variable X2GO_HANDLE_DAEMON is not empty. However, this variable is never filled, it seems. There is a variable X2GO_HANDLE_DAEMONS (note the extra S at the end) that gets set to "false" in some scripts. My guess is that these two scripts contain a typo and lack the S.

This is because x2goserver's install_config make rule still installs the file. -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 https://www.nwra.com/

x2go doesnt connect when using chacha ciphers
by bo0od 22 Jun '20

22 Jun '20

When im trying to connect it says: ``` key error: no match for method encryption client -> server: server [chacha20-poly1305(a)openssh.com] client [aes256-ctr, aes192-ctr , aes128-ctr , aes256-cbc , aes192-cbc , aes128-cbc, blowfish-cbc , 3des-cbc] ``` Though connecting using SSH works just fine. here is the sshd logs: ``` Jun 20 22:00:50 host sshd[4651]: Unable to negotiate with xxx.xxx.xx.xxx port xxxxx no matching cipher found. Their$ Jun 20 22:01:29 host sshd[4709]: Unable to negotiate with xxx.xxx.xx.xxx port xxxxx: no matching cipher found.

If you are asking what is my ssh and sshd configurations are you can find them here: (though its unrelated because ssh is working fine the issue is within x2go) client ssh: https://www.whonix.org/wiki/Ssh#Client_Configuration_File server ssh: https://www.whonix.org/wiki/Ssh#Server_Configuration_File

x2go doesnt work from Qubes OS
by bo0od 22 Jun '20

22 Jun '20

I wonder why x2go doesnt connect using Qubes OS? i have tested x2go from debian it works ok , but when using it from Qubes OS it doesnt connect with message saying "connection refused" though ssh works fine from the same machine on Qubes OS. So is there extra needed package to be installed? or its just unsupported? *Tested on Debian Buster Template ThX!

Bug#1477: x2goclient doesn't prompt for password after authentication failure if server is using google-authenticator
by Toby 18 Jun '20

18 Jun '20

Package: x2goclient Version: 4.1.2.2 I have installed Google Authenticator on my x2go server, and use keyboard-interactive for ssh passwords. If I mistype my password in x2goclient, it won't offer me another password prompt, but repeatedly asks for the Verification code until sshd on the server gets bored and closes the connection. Expected behaviour: if the login is not successful, prompt for both password and verification code again. x2goserver: Scientific Linux 7.7 - 3.10.0-1062.12.1.el7.x86_64 x2goclient: Fedora 32 - 5.6.14-300.fc32.x86_64 Cheers Toby
