Hello

I would like to know the range of ports used in EPSV mode by busybox
FTP to add them to my firewall
They seem to be over 50000 but is a precise range defined?

Can it be somehow changed and limited (ex: If I don't expect more than
10 clients at once, 50000 to 50010)

I didn't notice anything in ftpd.c
