SYSLOGS - Where can I find FTP activities

Greetings to all.
I need help from the experts. I have been given a FTP server script that runs all day, looking for files that are FTP'd to our machines. Its hoaky I know, but there are times that files are sent but somehow get lost. Is there a logfile I can view to see when files are received?

Thanks in advance,
Harley

Look for the file /var/log/xferlog - it is the default transfer logfile.
