* I configured SSH access with an account which cannot write to /etc/my.cnf (could not have such access because of IT security rule in my environment)

* Double click on the created instance but cannot open admin panel

* Output in terminal as follows:

$ /Applications/MySQLWorkbench.app/Contents/MacOS/MySQLWorkbench
 Debug level - 0

** (process:449): WARNING **: :718: link 'com.mysql.wb.menu.view.advanced' <object app.MenuItem> key=owner could not be resolved

    return self.expand_path_variables(self.settings.serverInfo['sys.config.path'].strip(" \r\t\n\b"))
AttributeError: 'NoneType' object has no attribute 'strip'

How to repeat:
* Create a server instance without configure SSH access.

* Double click on the created instance to open admin panel.

* Status bar will show that "Could not connect to target daabase: error calling WbAdmin.openAdministrator: see output for details"

* If open WB from Terminal.app, the trace information will shown in terminal window.

same problem here ...

installed Workbench v5.2.16 rev5249 on windows 7. Everything was fine at the beginning and I was able to use the server administration without SSH. I needed to use the Migration tool yesterday so I installed the old GUI Tools. Since that moment I am not able to open those server instances anymore ... the status bar is showing 'Could not connect to target database: error calling WbAdmin.openAdministrator: see output for details' ... I don't know how to get the 'output' on a windows machine though. Tried to uninstall and re-install again ... makes no difference. Still the same error message.

How do you configure your my.cnf without using workbench?

The MySQL server I try to connect is running on a debian linux PPC machine and is installed via apt-get.

The version of mySQL server is "5.0.32-Debian_7etch10-log". The my.cnf is mostly default value which comes with the debian package except that the IT admin allows MySQL server bind to instead of for management over network.

I used to connect to the same MySQL server with the MySQL Administrator in the MySQL GUI Tools Bundle without problem.

MySQL 5.0 is very old and unsupported.

More about this you will find here:


Please try with actual server version (5.1.45).

Just tested WB 5.2.18 beta2 against MySQL server 5.0 (5.0.32-Debian_7etch10-log) and 5.1 (5.1.37-1ubuntu5.1).

Now I can login into Admin panel without problem.

Sorry, I am not sure its beta2 or beta8...

Anyway, it is the latest beta release I can obtain and the revision number is "5.2.18-rev5648".
