Downtime today: packages.x2go.org (and git., bugs., code., lists. alike)
by Mike Gabriel 02 Mar '17

Hi all, due to some luck, I have time today to upgrade the machine hosting diverse X2Go and Arctica services (aka ymir.das-netzwerkteam.de) to a recent Linux OS and also move the machine (a VM) to a newer virtualization host. So expect availability to be sort-of wobbly today. Affected services: lists.x2go.org packages.x2go.org packages.arctica-project.org bugs.x2go.org git.x2go.org code.x2go.org light+love, Mike -- DAS-NETZWERKTEAM mike gabriel, herweg 7, 24357 fleckeby mobile: +49 (1520) 1976 148 landline: +49 (4354) 8390 139 GnuPG Fingerprint: 9BFB AEE8 6C0A A5FF BF22 0782 9AF4 6B30 2577 1B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de

X2Go crash from Mac/MATE to Fedora 25 w NIS user getting x2gostartagent: blocking creation of agent's keyboard file
by Robert Kudyba 01 Mar '17

01 Mar '17

This only seems to be affecting one user. He has a NIS account and has tried 2 NIS accounts to make sure. He's running a Mac with the latest X2Go (2.7.11) connecting to a Fedora 25 server with NIS, choosing the MATE desktop and audio disabled. We made sure to check the security settings as per this older post screenshot <http://lists.x2go.org/pipermail/x2go-dev/attachments/20151013/f02b140a/atta…> and confirmed the .Xauthority permissions problem <http://lists.x2go.org/pipermail/x2go-dev/2015-October/010733.html> does not exist. Here are some debug-enabled logs.

X2Go Client: Kex error : no match for method server host key alog: server [ssh-rsa], client [ssh-ed25519]
by jmmec2014＠yahoo.com 01 Mar '17

Hey everyone, Any advice on the problem below? I hit it consistently with X2Go Client, but it does not happen with the Pyhoca client. Error: Kex error : no match for method server host key alog: server [ssh-rsa], client [ssh-ed25519]. Client computer: * Windows 8.1 connecting to Linux Mint 17.1 (Ubuntu 14.04.1) running the MATE desktop. * X2Go client software v4.0.5.2. The problem does not happen with the Pyhoca software (I downloaded the latest version). Server: Linux Mint 17.1 (Ubuntu 14.04.1) running the MATE desktop. X2Go Server: Server Core: x2goserver (4.0.1.19) x2goagent (3.5.0.31) Server Extensions: x2goserver-extensions (4.0.1.19) x2goserver-xsession (4.0.1.19) X2Go Server Add-ons: x2gomatebindings (0.0.1.3) X2Go Server Features: X2GO_CLIPBOARD_MODES X2GO_LIST_DESKTOPS X2GO_MATEBINDINGS X2GO_MOUNTDIRS X2GO_MOUNT_UNCPATHS X2GO_PUBLISHED_APPLICATIONS X2GO_RUN_EXTENSIONS X2GO_SERVERSIDE_DESKTOPCOMMANDS X2GO_SET_KEYBOARD X2GO_UMOUNTSESSION_ALL X2GO_UMOUNTSESSION_ONLYPATH X2GO_XSESSION Additional Information: Usually I use X2Go without ssh keys, so just type in my userid & password when connecting to the Linux desktop. This has worked fine. When the problem above started to happen, I tried generating RSA keys on my Windows machine and transferred them to my Linux machine, but this didn't help. I also tried with DSA and also ED22519 keys, but no-go on X2Go. I installed Pyhoca and authenticate using my userid & password. I can then connect to the suspended session that was originally created with the X2Go client. For now I am using the Pyhoca client, but would also like to get the X2Go client working again. Thanks!
