Hello Lee,

> The unsecure ftp ports are 20 and 21, secure ports are 989 and 990.

I knew about 20 and 21 but have never heard of or used 989 and 990.

> You should also do a search for FTP Ephemeral Ports which I believe

Very interesting, I'll have a look.

> The Internet Assigned Numbers Authority (IANA) suggests the range 49152
> to 65535 (215+214 to 216-1) for dynamic or private ports.[1]

I see different port ranges used at different times. Leaves me wondering what
range of ports BBBS is using. :)

Thanks for the info.
