The unsecure ftp ports are 20 and 21, secure ports are 989 and 990.
You should also do a search for FTP Ephemeral Ports which I believe
passive uses which would be a range of ports that are dynamic..
The Internet Assigned Numbers Authority (IANA) suggests the range 49152
to 65535 (215+214 to 216-1) for dynamic or private ports.
Many Linux kernels use the port range 32768 to 61000.[note 2] FreeBSD
has used the IANA port range since release 4.6. Previous versions,
including the Berkeley Software Distribution (BSD), use ports 1024 to
5000 as ephemeral ports.
Microsoft Windows operating systems through XP use the range 1025-5000
as ephemeral ports by default. Windows Vista, Windows 7, and Server
2008 use the IANA range by default. Windows Server 2003 uses the
range 1025-5000 by default, until Microsoft security update MS08-037
from 2008 is installed, after which it uses the IANA range by
default. Windows Server 2008 with Exchange Server 2007 installed has
a default port range of 1025-60000. In addition to the default range,
all versions of Windows since Windows 2000 have the option of specifying
a custom range anywhere within 1025-65535.
