mouse 1 cm too low
by richard lucassen 17 Apr '21

17 Apr '21

Hello list, I have run x2go for many years now without any problem. I have two different servers running Debian testing and x2go 4.1.0.3-5, multiple clients running the same OS and x2go client. I run WindowMaker both on client and servers. This has worked for many years. Weird thing: the active clicking point for the mouse is 1 cm above the mouse. Restarting client and server does not make any difference. AFAIK these x2go versions have not changed (underlying libraries might have of course). I tested this on a few clients: same problem. It make x2go almost unusable. Anyone a hint what to test and where to look for this weird issue? R. -- richard lucassen http://contact.xaq.nl/

x2gothinclient_create seems to fail

Hello everybody! I don't know if this is the right place or the right way for asking for help, thank you for pointing me in the good direction if not. Meanwhile, I'm trying to set an x2go TCE by carefully following this how-to: https://wiki.x2go.org/doku.php/wiki:advanced:tce:install <https://wiki.x2go.org/doku.php/wiki:advanced:tce:install> I never get to this point :'During installation you will be asked to configure your thin client's default language and default keyboard settings. Please do so. Hint: make sure you use UTF-8 encoding in your language selection (e.g. en_US.UTF-8, de_DE.UTF-8, etc.).'

X2Go Desktop sharing view-only mode?
by Jakob Czapski 28 Dec '20

28 Dec '20

Hello all, please tell me if there is an option on the server side to force all clientside connections to be viewonly? The purpose is that for educational & security purposes clients should not interfere with the presentation nor the system itself. Thank you in advance for your help!

X2Go fails to connect when SSH config contains multiple jump hosts
by Konrad, Martin 08 Dec '20

08 Dec '20

Hi, I have a few hosts in my ~/.ssh/config file which have ProxyJump lines specifying _multiple_ jump hosts: Host foo ForwardAgent yes ProxyJump first.example.com, second.example.com It seems like X2Go doesn't like this kind of configuration. I complains when I try to establish any connection (even when trying to connect to other hosts which don't have a line like this): "Cannot connect to first.example.com:22 Failed to process system configuration" Everything works fine in cases that require only a single jump host. As far as I can tell from the ssh_config (5) man page my configuration with multiple jump hosts is valid. Any suggestions how to deal with this?

What is the hash algorithm / format used for the host key hash during connection instantiation?
by Stefan Mätje 07 Dec '20

07 Dec '20

Hi, I'm using x2go to connect from a Linux Mint (19) machine to an Ubuntu server using a RSA key over SSH. During the connection instantiation x2go presents me the following question: Der Server ist unbekannt. Vertrauen Sie diesem Host-Key? Hash des öffentlichen Schlüssels: remote.server.com:22 - d7:2e:e0:ae:27:7a:e5:33:59:6d:00:12:75:22:0a:c6:9a:10:31:a9 I. e. "The server is unkown. Do you trust this host key?" I now have problems to match the presented fingerprint hash to the host identity keys that are present on the server machine under /etc/ssh/ssh_host_*key*. When I later inspect the .ssh/known_hosts file on my Linux Mint machine (client side) I can match the public key there to the public host identity key on the server side that has the following fingerprints (displayed with 'ssh-keygen -l -E {md5|sha256} -f ssh_host_ecdsa_key'): ssh_host_ecdsa_key.pub: 256 SHA256:3vf9PbLKhlaFpff7SxpaDLyrfYJF8iJ+Px3bMzLNY2U root(a)internal.server.com (ECDSA) 256 MD5:7b:9a:76:4b:58:ce:87:bf:3f:56:41:a9:7c:f8:bf:e9 root(a)internal.server.com (ECDSA) Neither of these fingerprints can be matched to the fingerprint / hash that x2go presents to me. The MD5 hash line is similar but shorter (only 16 hash bytes aka. 128 bits that matches a MD5 sum length). The x2go hash has 20 bytes (160 bits) hash length. The question is how can I reliably match the fingerprint x2go presents to me to the right host ID hash. Am I comparing / expecting the wrong keys? Can somebody please shed some light on this issue. Best regards, Stefan
