ismail bushra:
am very sorry i make it complex my question is 1 why fedora not have #netconfig command, because i feel it make easier to configure the nic
Vivek J. Patankar:
Try "system-config-network-tui" as root.
Not knowing what the original poster gets with "netconfig" there's also "setup" and /sbin/ifconfig and graphical network configuration (drop the "-tui" from Vivek's suggestion).
