do you have more details about this live cd? what is it? Knoppix? Either way i'd think that the error you have is possibly down to a missing entry in /etc/services, or a missing file altogether. Why a suitable entry would be missing I coulsn't say... i have an entry in mine that reads:
Code:
ftp 21/tcp
ftp 21/udp fsp fspd
make sure you have a suitable equivalent in yours
