I have to enable the root account first in order to use "su".

Subject: RE: [PIC] PICC Lite problem under Linux Don't forget, if you need to do something as root, you can type "su" and enter your root password, to temporarily get root privileges. You don't need to enable the root user. jon -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
