I'm trying to convert my use of NetInfo APIs to Directory
Services APIs, and I'm having problems. I want to access the DHCP
information added by Internet Sharing, which is stored in
NetINnfo at /config/dhcp/subnets. However, dscl consistently
complains that /config/dhcp/subnets is an invalid path. To
duplicate:
1. Turn on Internet Sharing in Mac OS X (System Preferences ->
Sharing -> Internet)
2. From Terminal, query Directory Services:
dscl localhost -list /NetInfo/config/dhcp/subnets
In the NetInfo Admin Utility you can see that this path exists
and has children, so why can't Directory Services see them?
because you should have run the command in interactive mode and
found out that you don't need the leading /.
So:
dscl localhost -list NetInfo/Config/dhcp/subnets
Nope, that still doesn't work. Without the leading slash, I still
can't see children in NetInfo/config/dhcp. If I use:
dscl localhost -list NetInfo/config/
I can see AppleFileServer, dhcp and ntp listed as children, but if
I use
dscl localhost -list NetInfo/config/dhcp
It has no children. Typing
dscl localhost -read NetInfo/config/dhcp
I see several propertis lie dhcp_enabled and
detect_other_dhcp_server, but I don't see the subnets child. It
still shows up in NetInfo Manager though. Arg!
Directory Services/Open Directory does not support arbitrary nesting
in the way that NetInfo does... each node has a flat list of record
types and within that is a flat list of records. However, It is
possible to do what you want using native record types, but the /
delimiter can sometimes be a challenge to pass in to dscl properly
due to the shell.
If you are using the DS API, you can use a record type of
dsRecTypeNative:config/dhcp/subnets and then just use the appropriate
record name for each subnet.
The two backslashes are needed since the shell usually converts those
to one backslash before passing to the tool, and slashes that should
be part of the record type or the record name need to be escaped.
Hope that helps,
