[Hampshire] Linux problems

Hello I have 2 questions I wonder if anyone could help me with ?

1: When trying to install madwifi drivers on a fedora core 6 laptop I
got this message :

[drystan@Angelmob madwifi-0.9.2.1]$ make
Checking requirements... ok.
Checking kernel configuration... ok.
make -C /lib/modules/2.6.19-1.2895.fc6/build

2: when using SSH if my public key is in the authusied keys folder I
should not need a password to log into the server ? Is this correct
because I copied the file in but I still need a password

Many Thanks
