vsftpd comes with fedora core installation...i.e. you've opted for it during installation.
the config file is located in /etc directory and called vsftpd.conf. I'm mentioning slackware linux file location which may be slightly different from fedora. You could try
# locate vsftpd.conf
If my memory serves me right, fedora turns on the the vsftpd daemon by default. You could check via this command
# ps aux | grep vsftpd
If it is not running, you could modify config file (by hand or via a gui utility...i'm sure there would be one) and start the service and test it out if it works.
You could also look at google
to look for tutorials.
