Interpreting the FTP Transcript

[httpwebwitch]

I'm troubleshooting some FTP problems.

When I connect to my server, I see this in the transcript:

Cmd: PASV
227: Entering Passive Mode (aaa,bbb,ccc,ddd,12,217)

I understand what Passive mode is. aaa.bbb.ccc.ddd is my server's IP address. But what do the last two numbers represent?

[phranque]

the last two octets specify the port used for transferring data, so in your example it is (12*256)+217 or port 3289.
the port number will always be >1023 as these are the unprivileged ports.
