Webmin
 

-hello i installed samba from the package manager. i downloaded webmin and installed it too. but when i run webmin from the browser it wont accept my administrative password and username. it wont even accept the default username and password which is root.

To configure webmin, there is a script called setup.sh that you need to run. Webmin doesn't use your system login names and passwords, so this file gives you the chance to set them up. Have a read through this for more details.
