While downloading a tar ball from gnu's FTP server, I found that other than standard 21 TCP port connection, I also seeing an extra connection:

tcp        0      0 192.168.1.109:45056     208.118.235.20:21       ESTABLISHED 10956/wget          
tcp        0      0 192.168.1.109:56724     208.118.235.20:22259    ESTABLISHED 10956/wget 

What that port is used for? I checked /etc/services, only 20 and 21 should be in use, am I wrong?

The command in use was wget 'ftp://ftp.gnu.org/gnu/tar/tar-1.26.tar.xz'
