I have installed a standard Redhat 9 server along with webmin version 1.0, for some reason when using webmin its very very slow, i was using Redhat 7.3 before and it was fast, well normal 10/100 speed... :(
Try upgrading webmin 1.0 is old, the current version is 1.110. This may help you. You can upgrade webmin from one of the menu's (I forget which one, I havent used it in a while, and its not installed for me to check anymore). Just click around, you will find it.
