RE: DHCP on the AS/400

DHCP is one of those services that, depending on your size, needs to be up 24x7x365. If you're a 20 device shop the i5 DHCP would be a good choice as you can most likely schedule and i5 upgrades when no one is at work. For us I could not see us being able to tell the entire school (4,000 on campus PCs) that they can't access the internet today because we are doing an install of V6R1 even if that was done on a Saturday night. So if you run a large shop DHCP is one thing you should run on a box that does nothing else.

Albert,

Our little 20-device shop has used i5 DHCP for... I dunno... ten years and never
had to do a thing to it. It just runs. Configure with iNav, the config file lives
in "QIBM\UserData\OS400\DHCP\dhcpsd.cfg". Ours is shown below for reference.

Does anyone use DHCP on the AS/400? How is it configured? Can I turn it on
"out of the box" and expect it to work?
Thank,

Albert
