[CentOS] ftp issue in Centos 5.3

I manage a small server that I back up weekly. I do this by making a  
tarball of relevant files then transferring it over the local subnet  
to my station (Fedora 11), whereupon I burn it to DVD. There is no  
optical burner on the server. The tarball amounts to a bit under 5  
gigs. Recently I've started getting an error telling me to try PASV or  
PORT first. I use the gFTP client on my machine and as far as I know  
there is no option in this program to use either option either locally  
or remotely (on the server.)

Any ideas on this one?

When addiction becomes commonplace in a society, people become  
addicted not only to alcohol and drugs, but to a thousand other  
destructive pursuits: money, power, dysfunctional relationships, or  
video games. A social perspective on addiction does not deny  
individual differences in vulnerability to addiction, but it removes  
them from the foreground of attention, because social determinants are  
more powerful.
