No. The problems is vsftpd trying to (reverse) lookup host/IP
name of the client, which if not possible takes some time until
timeout occurs.
Possible solutions:
- Setup DNS for your LAN if your haven't, if so the FC3 box is
just missing the proper nameserver entry. (www.tldp.org) has a
great DNS Howto.
- Setup /etc/hosts. ('man 5 hosts')
- Use proftpd or alike ftp server which allows to switch of DNS
lookups. (vsftpd IIRC doesn't)
