Re: re-IPL necessary

[Philipp Rusch <philipp.rusch@xxxxxxxxxxxx>]

Jim, what is your internal IP-scheme ? Is it 192.168.0.x ?
The console over that serial cable uses a "modem-device" and a ppp-like
connection with tcpip adress pair of 192.168.0.1 and 0.2 to establish a
session between pc and AS/400.
You CANNOT use this network numbers for other purposes, nor can you
change it for that serial connection.
I had very strange results before I found out about this.
YES, there is an option in DST to change that network numbers, but as
I found out in long experiments with several IBM calls this doesn't always
"stick" to another number, sometimes on next IPL you are back on the old IPs.

HTH, regards from Germany, Philipp Rusch
