error

I had a system with an odd little problem. The user was using Excel 2003 and all of a sudden, it looked like Excel hung. Everywhere the user clicked with the left mouse button, nothing happened. The right button would select a cell an inch away from the cell that was clicked on and the pop-up menu would appear down and to the right from the point clicked. While Excel looked like it was hung, it really wasn't as even though it wasn't behaving, it was running...

When upgrading Zimbra, one of the first things it does is check your hosts file for two entries. It needs a valid localhost entry (the mysql setup is sensitive about this) and it needs a valid host FQDN entry for the server itself.

It wants to see something like this:

192.168.12.5   mail.xxxxxxxxxxx.com mail
127.0.0.1      localhost.localdomain localhost

The upgrade script kept complaining that my hosts file was incorrect, but those two entries where there and they looked fine.

Here's the error (sic):

 ERROR: Installation can not proceeed.
  Please fix your /etc/hosts file

So...
