Yes. 4.1.4 includes a DHCP server. It even includes a hook to
recompile the named forward and reverse lookup tables. We personally
use the DHCP server in a static mode (ie, we assign IP's based on a
specific MAC address) so we do not need feature. The DHCP server
also includes support of BOOTP clients (in our case HP JetDirect
Printers).
The only real problem I encountered with the AIX DHCP server is
that when a specific client entry is changed to reflect a new MAC
address (ie a machine replacement or upgrade to a new NIC) the DHCP
server did not pickup the change when the you refreshed the server.
My only recourse was to stop the DHCP server (stopsrc -s dhcpsd) and
delete the client reservation database files (dhcpsd.ar and
dhcpsd.cr). Then I would restart the server. This caused the
obvious problem of clients having their IP reservation expire early.
This bug was supposed to be fixed with the latest patch level. I
haven't had tiime to verifiy.
Another problem that affected me was the while you can define
default IP settings for specific subnets. For example for subnet
aa.bb.cc.dd I can supposedly setup the DNS server, Subnet Mask, etc.
for all nodes in the subnet. The problem is that I doesn't work.
It merrily ignores the IP settings for the subnet (possibly because we
are using DHCP more as a BOOTP static IP assignment service). We
found that the IP settings worked for global assignments and client
specific assignments.
