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
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.
If, under Windows, the controls in the windows look somehow
displaced, select Settings tab and click the
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.
