B.1. Troubleshooting Connection Errors

If an error occurs when you select a connection profile and attempt to establish a connection to the MySQL server named in the profile, a window containing error information will be displayed (see figure).

Normally, this means either that the credentials specified in the profile are wrong (wrong username, wrong password), or that you do not have privileges to connect to the MySQL server from the client machine. See Causes of Access denied Errors, for more information.

However, another cause of connection failure is that there might be a network problem that prevents you from reaching the machine where the MySQL server is running. For this reason, the error dialog provides a PING button. Clicking this button will send an ICMP PING request to the MySQL server host machine. If the host machine is available over the network, you will see something like this:

Reply from 127.0.0.1: Time=0ms TTL=128
Reply from 127.0.0.1: Time=1ms TTL=128

This would indicate that the machine is reachable, and that the cause of connection failure is not a network problem.

B.2. Troubleshooting Display Problems

If, under Windows, the controls in the windows look somehow displaced, select Start, Control Panel, Display. Select the Settings tab and click the Advanced... button. Change your DPI settings to Normal (96 DPI).

If, under Linux, messages and captions appear very big, your display resolution is probably set too high. Use gnome-font-properties to change your default font to a smaller value or go to Details and set your resolution to 72 or some other more appropriate value.
