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'
