DBDesigner4 loads fine on the PC Laptop, but it cannot connect to mysql on iocean. It gives the error message:
“Connection to database failed.
dbExpress Error: Invalid Username/Password”

I know for fact the username/password I am supplying are valid. They work fine from other remote areas, including the DBDesigner4 installation on the Linux server.

There is a documented issue about DBDesigner4 being incompatable with MySQL 4.1 or higher, and a password workaround is needed. This, however, does not apply to us.

After tinkering with the issue for a while yesterday, I’ve about run out of options, and I’m ready to forfeit any attempts to use DBDesigner4 on the PC. My initial interest was that DBDesigner4 would run faster on the PC than through the X11 forwarding/ssh connection because it is a desktop application. However, with the discovery of the -Y argument to enable “trusted X11 forwarding”, my interest in using the PC is now moot. From the Linux server, I can now run DBDesigner just as quickly on various remote systems, all while using the server as a central repository for schema files and images.

If we happen to stumble across a solution or workaround for DBDesigner4 on the PC, or if an upgraded version of DBDesigner is released, we can re-investigate using the application on the PC. Until then, I feel it is a waste of time to actively pursue a fix, especially considering the working instance of DBDesigner4 on Linux.
