What needs to be loaded on a server to connect to remote manager via a
web browser?

Somehow, all of Linux servers with OES 2 have a problem with remote
manager. One day I can log into the remote manager and then the next day
I could not. It just said the page cannot be displayed. I am still very
new to Linux. Can someone tell me where I should look into to fix this

By the way, I check and make sure apache2 is running and novell-tomcat5
is running. But novell-httpstkd is not running and tomcat5 is not
running either by default.

Thank you very much!
