Re: [X2Go-User] trying to use x2go on windows and could not make it work
Glad that changing the version worked for you. The links on that page link to version 4.1.2.0. Hopefully, the team will have a fix for version 4.1.2.2 sometime soon. That way we can take advantage of the updates in it. The version of the server on RHEL6 is definitely buggy in my experience. I am presuming you are getting it from EPEL6 for CentOS6, so you are you getting the same version. Here I require RHEL7 for those deployments due to the instability of it on RHEL6.

Re: [X2Go-User] trying to use x2go on windows and could not make it work
Does the application complete crash and exit? Mine would just crash the application completely. Mine was due to the server requiring FIPS and the application not gracefully handling the fact that it doesn't handle FIPS. Do you know if the server is hardened? For me, version 4.1.2.0 did handle it OK. You can try running the current version (4.1.2.2) in debug from the command line to see if it shows any errors before it crashes. Mine didn't, but your problem might be different. If you do decide to try the older version of the client, you can get it here: https://code.x2go.org/releases/binary-win32/x2goclient/releases/ . Good luck. If you do figure something out, I am hoping that it might help me make it work for me as well.

The hardening is one of the security profiles that comes with RHEL7.7. Either the USG or the NIST 800-171 profiles. We use those as a starting point for our configuration. On the specific RHEL7 VMs I am running, I was able fix the problem by doing two things (and both needed to be done). 1. Disable fips by removing fips=1 from grub. 2.

I am using the gui to configure and I have unchecked "Enable sound support" and "Client side printing support." There are no shared folders configured, but I didn't see a way to explicitly disable that. Generally, I have toggled just about any option to see if I can get it to work.

Re: [X2Go-User] X2Go Windows Client 4.1.2.2 Crashes Upon Connect
I stood up some test machines to figure out the issue. I have the issue on a clean RHEL7 machine with lots of packages and some security hardening done on it. It does not happen on an Ubuntu MATE install or on a RHEL7 minimal install without hardening. I need to track down the issue to see if it is something that might be able to be fixed. I tried simple things like reverting the sshd_config and setting selinux to permissive. While running with --debug and --libssd-debug, there is nothing obvious. With --debug, the last statement is a mention that the ssh port is 22 (right before it calls ssh_connect, I think). With --debug and --libssh-debug, the last statement seems like what I would consider benign ssh message passing. There is really not much of interest. The only warning that I see at all is that /etc/ssh/ssh_known_hosts doesn't exist. Does anyone have any ideas of what I should look at? It has to be something that changed in 4.1.2.2 over 4.1.2.0, since the latter still functions OK.
