ftp daemon

[penzk001]

Good afternoon,

I was asked by our security team the port that the ftp daemon ((Version 4.1)uses in passive mode. Is the any document/config file that has these details ?

Thanks

Try this:
1) open a ftp on your server, connecting to itself
2) from another unix session issue "netstat -a > results_1"
3) from the ftp shell issue a "passive" command
4) from the other session issue "nestat -a > results_2"
Check the difference

An internet search on 'passive ftp' gives a lot of hits for passive ftp. A particularly useful page is
