FTP - Security & audit

[Ben Akiba <asfour00@xxxxxxxxx>]

OK, security gurus, here is a situation:

FTP client on PC, FTP server AS/400, boxes A and B, V4R5. Put a file
from PC to A, put a file from PC to B. Files overwritten.

QAUDJRN on A contains entry type SK (Secure Sockets connection) with PC
internet address and AS internet address, then SP (Swap profile) showing
swap between MyUserId and QTCP, and finally 4 entries showing that file
was cleared and written into (file is under OBJAUD *CHANGE).

QAUDJRN on B contains everything except first entry (SK with address of
client requesting transfer).

Client and servers are on the same (fairly complex) network, and routes
are not necessarily the same (actually boxes A and B don't "see" each
other). No exit programs so far, but working on it.

Question: what is different in set up, so auditing of Box B doesn't
reveal requester's address. I guess, it might have something to do with
SSL, but I didn't notice ports (443?), other that "FTP - well known" on
box A. Any ideas? Solutions?

Bonus question:
Completely unrelated, what would be a typical server command for the FTP
SERVER running on the PC, so that I can run command on PC from FTP
client on AS? (Once again, don't confuse this problem with previous one,
this is totally opposite situation)

Thks.
