RE: IP Address of AS/400 Machine

["Segars, Steven " <Steven_Segars@xxxxxxx>]

Just an FYI - Your IP addresses are contained in the files QATOC* located in
the QUSRSYS library. As HTH suggested below, that file contains the IP
addresses. This is also useful when you have to restore another system and
you want the same IP addresses on that box. Just restore the QATOC* files.
But keep in mind it will over lay the IP addresses on that system. use with
caution.

Hi

This is exactly why DNS and host tables are used (yeah, Rob, those evil 
host tables <g>). Do you have a corporate DNS server? If not, put the IP 
names of the 400s in a HOSTS file on the non-400 machine. Then the alias 
names are available. Maintenance problem? Yes, but so is keeping the DNS up 
to date. One of your 400s could be the DNS server.

Otherwise, there is an interface table, QUSRSYS/QATOCIFC, that has all the 
IP addresses defined for your system.

 From V5R1 on, there is an API, QtocLstNetIfc (List Network Interface), 
that will give you all the interfaces, along with status and other
information.
