Bug #59034	Trying to mange a linux host via SSH tunnel (or NAT tunnel) leads to crash

Category:	MySQL Workbench: Administration	Severity:	S2 (Serious)
Version:	5.2.31.7115	OS:	Windows (Windows 7)
Assigned to:		CPU Architecture:	Any

Description:
I am running:

1) Windows 7 as host
2) CentOS 5.4 x64 in a VM 

If I use an SSH tunnel (or a NAT port forward) so that the MYSQL running in the VM is available on either localhost:22 or localhost:3306, I am not able to remote manage the instance.

It looks like MYSQL Workbench assumes that because the instance is localhost, it must be Windows, and tries to configure WMI management which actually crashed workbench for some reason.

It seems like there should be a way to skip Windows management if I know that I am tunneling a remote machine onto my local machine.

How to repeat:
1) Install MYSQL in VM using NAT
2) NAT port forward both 22 and 3306 in the localhost to the VM
3) Trying administering the server either via SSH or via direct connect on localhost

Expected: I am able to do this.

Actual: Workbench seems to insist that it is a Windows instance and then crashes during the new server wizard when it is trying to configure windows remote management.

Hi Matt,

could you add the stack for the crash and add this to the post? you can gather that information by right-clicking somewhere in the crash-dialog and select "copy stack to clipboard.
I cannot reproduce the crash on my systems, but I see the problem with setting up an instance withforwarded ports and 
According to your description this looks very much like Bug #58922 - if you can add the stack we can probably verify if its an exact duplicate.
thanks in advance

This does look like a duplicate BTW.
