ports and ftp

hi, I'm working on a 7.0, and have a slight problem... everything seems to be rightly installed, but there should be a "small" configuration problem (I haven't installed the box). I can't ftp the box. i'm answered "ftp: connect: connection refused". if I nmap the box, the ftp ports are not "opened"... is it normal ? Where am I to look to solve this problem ?.... Regards Stephane
