I'm waiting for some clarification on what they mean by "random high
ports", but I suspect they are talking about the command and data
ports the client PC is selecting and not those of the FTP server. If
my understanding is correct, the client PC can randomly assign its own
command and data ports.
If this is the case (they are talking about the client PC's ports), is
there a way to assign the command and data ports of the client PC
using Kermit?
