“SQLyog bombs out with “Unable to start Plink 2:The system cannot find the file specified”
To my best belief this is not correct. It must be the OS that sends this message an not SQLyog. Alone the fact the the message is instantaneous tells that!
However, this “SSH Error: FATAL ERROR: Network error: Connection Timed out.” error message is a PLINK err. msg that SQLyog 'picks up' and sends to the screen.
And this look pretty weird actually! First the OS tells that plink cannot be started. But obviously it IS started – because if it was not it would not be able to issue an error message!
Isn't it possible to give READ and EXECUTE permission to all (also non-admin) users to plink.exe or the complete SQLyog installation folder? I must admit that I know almost nothing about the privilege system on Windows Server systems. But that could be the issue.
Please report any findings!
