I am complete new in linux.
And i want to know that how to make AD-HOC network using WPA_supplicant?

Any help

What distribution+version of linux, and which version of wpa_supplicant are you using? FWIW, this is a pretty new enhancement, so you may need to get current sources and build it from scratch.
