FYI: I updated the Fedora Rawhide mock files onjenkins
by Michael DePaulo 31 Mar '15

31 Mar '15

On Japsand, which Jenkins builds on, I updated the mock files (/etc/mock/*.cfg) for Fedora Rawhide to their mock 1.2.7-1 versions: https://apps.fedoraproject.org/packages/mock/changelog/ One of the differences is that the rawhide RPMs now have "fc23" instead of "fc22" in their names. I started rebuilding the Rawhide packages through the Jenkins WebGUI. I intend to finish doing so tonight. -Mike#2

X2Go Session Broker, now with load checker service
by Mike Gabriel 30 Mar '15

30 Mar '15

Dear all, within the last week I have been working on X2Go Session Broker a bit more, pushing it towards release 0.0.3.0. One feature, that was still missing, was a means to perform load checks on associated load-balanced X2Go servers, so that a real "load" balancing could take place. Until last week, server load was detected by only counting the number of running / suspended X2Go sessions. If you have users that are working hard on an X2Go server, then the number of sessions is a very inaccurate way of detecting server load. So now, we count X2Go sessions plus detect a couple of server metrics (via a background daemon, aka x2gobroker-loadchecker). All gathered information will be combined into a load-factor. The load-factor and the number of running/suspended sessions, will decide on what host the next new X2Go session will be started. Quick install for testing the new feature (from the nightly builds, of couse): Debian: apt-get install x2gobroker # will update your x2gobroker packages apt-get install x2gobroker-loadchecker -> make sure x2gobroker-loadchecker starts via your init system edit /etc/x2go/x2gobroker.conf, set use-load-checker for inifile broker backend -> make sure, you have at least one session profile setup in /etc/x2go/broker/x2gobroker-sessionprofiles.conf that uses more than one host -> make sure, that you use "broker-agent-query-mode = SSH" for this session profile. -> for the fully-featured show, enable X2GOBROKER_DEBUG in /etc/x2go/broker/defaults.conf Now watch /var/log/x2gobroker/loadchecker.log and /var/log/x2gobroker/broker.log for system load information. I'd be happy to receive some test results within the next couple of days/2-weeks. The 0.0.3.0 release is heavily overdue and I would like to finalize this version by the beginning of April.

Bug#830: QAction::eventFilter: Ambiguous shortcut overload: Ctrl+Q
by Mike Gabriel 30 Mar '15

30 Mar '15

Package: x2goclient Version: 4.0.4.0 Severity: minor This mail's subject says it all: QAction::eventFilter: Ambiguous shortcut overload: Ctrl+Q. When hitting Ctrl+Q in X2Go Client, I would expect X2Go Client to close. However, it only throws the above message on the underlying terminal if launched from one.

Bug#832: X2Go Client in broker mode wiath autologin enabled expects transmission of private SSH key file
by Mike Gabriel 30 Mar '15

30 Mar '15

Package: x2goclient Severity: important Version: 4.0.4.0 If brokerage with autologin is in use (a very common broker setup), the current client<->broker communication design in X2Go Client is that the broker creates a SSH pubkey/privkey pair and transmits the private key to the client. Never should we transmit private key files over the wire!!! The X2Go Session Broker is already able to accept pubkey files from the client side and deploy those pubkeys appropriately. In Python X2Go, this is already used. X2Go Client should switch here: create pubkey/privkey pair on client-side, push the pubkey to the broker and have it temporarily deployed from there to the X2Go Server where the next session login is scheduled by the broker.

Bug#831: handle autologin failures via broker gracefully
by Mike Gabriel 30 Mar '15

30 Mar '15

Package: x2goclient Version: 4.0.4.0 Severity: minor With brokerage enabled, the broker can mediate an autologin mechanism from X2Go Client to a given (brokeraged) server. The mechanism is this: o broker deploys a public key in ~/.x2go/authorized_keys on X2Go Server o X2Go Client receives the corresponding private key o (the above is already flawed, no private keys should be sent over networks, I will file another bug for that) o in SSHd, the ~/.x2go/authorized_keys must be configured as potential place for authorized_keys file If the last step is forgotten, SSH authentication with X2Go Client against the X2Go Server fails. If that fails, my expectation would be a fall-back to username / password authentication. But what happens, is: X2Go Client "gets stuck" in the session startup procedure (it's not a real freeze), it does not return to the login dialog widget anymore. Options remaining: closing X2Go Client and reopening. I stumbled over this because of a configuration in SSH daemon on one of my test boxes.

nx-libs SetPictureFilter() crash fix
by Mihai Moldovan 29 Mar '15

29 Mar '15

Hi Jan, The following patch will probably interest you, because it fixes the crash in SetPictureFilter(): http://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=debian/patches/0017_nx-X… Incidentally, this was also the reason why nxagent on my Gentoo system always crashed when clicking on any button in a XFCE desktop session. This fix will also be included in the next nx-libs release, but I haven't plan a date for this yet. Probably not coming any time soon, especially due to the previous emergency releases a few weeks back... Mihai
