Subject: ssh broker : load balancing not working

Date: Tue, 13 Feb 2018 18:13:03 +0100 (CET)

package: x2gobroker-ssh
version: 0.0.4.0-0~972~ubuntu16.04.1
priority: bug

Hi,

Tried using x2gobroker-ssh (0.0.4.0-0~972~ubuntu16.04.1) instead of classical http broker and finaly got it working but in ssh mode, load balancing on my server farm is not working, every session is redirected to the same server (the first one) while it is balanced correctly with the http broker on the same broker server.

I would love to send logs but it seems this broker don't produce log files or I couldn't find a way to get them.


Regards,
Walid Moghrabi

The issue has been a user privilege issue when init system is systemd.

It got fixed by  
https://code.x2go.org/gitweb?p=x2gobroker.git;a=commitdiff;h=00b89c53a793a535657a80b5a14cc05ad70bda82 and possibly follow-up  
commits.

It will be fixed with release 0.0.4.0 of the X2Go Session Broker.

     - bin/x2gobroker: If binding the http server fails, a non-zero exit code
       should be returned. (Fixes: #1013).
     - x2gobroker/loadchecker.py: Don't re-read the x2gobroker.conf during
       each cycle of the load checking loop. Rather read it on service startup
       and require a service restart when x2gobroker.conf has been changed.
     - x2gobroker/loadchecker.py: Avoid rare cases where at the end of a load
       checking cycle a negative sleep time would have been calculated.
       (Fixes: #1315). Thanks to Walid Moghrabi for catching this.
     - HTTP broker: Add &login=<server_user> support to plain and json broker
       frontends.
     - SSH broker: Add --login option. This now supports X2Go Broker user and
       X2Go Server username being different accounts.
     - bin/x2gobroker: Correctly use split_host_address() function call.
     - bin/x2gobroker: Don't override already defined logger objects, define
       them properly where needed.
     - Convert one more unicode object into (Python3) string.
     - x2gobroker/tests/test_broker_agent.py: Assure that tests are run without
       loadchecker usage.
     - broker-use-load-checker profile option: Also tolerate 'TRUE' and 'True'.
     - x2gobroker/agent.py: Fix failing execution of LOCAL broker agent. As
       the LOCAL broker agent is executed setuid root, we cannot
       Popen.terminate() (which is unneeded anyway) the process after its
       execution.
     - Ignore SSH broker events for now. Not sure if we will ever support that.
     - Finalize API documentation.
     - Fix regression flaw in x2gobroker/web/json.py, introduced by commit
       9fa371e9.

   * New upstream version (0.0.4.0):
     - src/x2gobroker-{agent,ssh}.c: catch errors in setuid wrappers and add
       general return clause to make compilers happy.
     - Makefile: make sure that we actually append our custom CFLAGS and
       LDFLAGS values, even if passed in through the make command line.
     - src/x2gobroker-{agent,ssh}.c: fix compile warnings/errors.
     - src/x2gobroker-{agent,ssh}.c: fix more compile errors.
     - misc: copyright update.
     - misc: switch to HTTPS-based URLs where appropriate.
     - man/*: update date and version stamps pre-release.
     - misc: add missing coding modelines.
   * x2gobroker.spec:
     - Add %debug_package macro when debugging is to be enabled, hoping that it
       will actually generate proper debuginfo (and -source) sub packages
       owning files.
     - Whitespace only.
     - Remove obsolete EPEL 5 support.
     - Switch to HTTPS-based links.
     - Use more curly braces.
     - Pull in gcc and redhat-rpm-config.
     - Re-enable debug file generation to see which OS versions still fail.
     - %exclude does not work with curly braces, revert.
     - Remove %debug_package macro usage, breaks builds nowadays.
     - Pass down global flags in CFLAGS and LDFLAGS.
     - Fix %{__global_ldflags} usage if variable does not exist.
     - Commands don't seem to work when wrapped in curly braces (at least on
       *SuSE), so revert.
