Hallo Svit,
hier eine kleine Hilfe:

Next you have the Host name. You define this from CFGTCP command, and take option 12.* This is the machine name according to TCP/IP, and should be the same as the machine name.* This name can get resolved to a TCP/IP address either via DNS or via the host table.* The host table is option 10 on the CFGTCP command.* Most places will have an entry in here which connects the Host name to a TCP/IP address via an Interface (The interface is defined on CFGTCP option 1).* *
