Address already in use You are running a program that is trying to use the same network port as another program that is already running, or, it means a program recently finished executing (within the last 90 seconds) that was using the same port as the program you're running, and the operating system is holding the port open for a 90 second timeout period. rresvport(): Permission denied Make sure the suid bit is set on the 'rush' binary, and that it is owned by root. got 'uvw', expected 'xyz' You are probably have mismatched versions of rush running on the network.

Your browser will search for the page and then deliver an explanation as to why it couldn't be found. Each carries a specific number and most carry a proper explanation of the issue. Examples: Server Error - the computer you are trying to connect to is suffering a problem. Error 404 - page not found. Error 403 - you are not allowed to see this page because you do not have permission of the company operating the Web site.
