We have an AS400 V3R2. All our customers in Europe are connected to this via some methods (dialup,internet...) and with different emulation programs (PCOMM, ClientAccess, passthru from other AS400 or mainframe...) , TCP/IP and SNA. What I have to check to avoid "illegal" upload/download fro/to my AS400 ? The only thing I have actually is a special program that check the accesses. It is activited via the Network Attributes (PCSACC Client Request Access) but it seems to work only when we use a PCOMM file transfer, not a ClientAccess file transfer ... Is there someone somewhere who can help me ?
