Distribution: Net-ISC-DHCPd-0.05 Perl version: 5.10 Operating System: FreeBSD 8.0 So I'm trying to use OMAPI to edit and search through a lease file on a test DHCP server by using the Net-ISC-DHCPd-0.05 distribution but I've run into some issues. I'm able to query the lease file with an IP address and get the lease information for that lease associated with that IP but I'm trying to query it with state = active but I get an error "can't open object: not implemented" I notice that state has actions: examine and lookup which I think should allow for the read action to work since that's the only requirement I believe for read to work. Thank you for any feedback! - Jeff

Hi, There's at least a bug in the documentation: The "state" is indeed read-only. Will investigate it more closely tomorrow. Maybe I need to rewrite that bit now when I know Moose better... What do you mean about "but I'm trying to query it with state = active". Do you mean you're trying to set it? Or using it as a lookup? Could you attach the code you're working on? ___ .jht On Tue, Jun 15, 2010 at 4:14 AM, jeff bair via RT <bug-Net-ISC-DHCPd@rt.cpan.org> wrote: Show quoted text

Hi Jan, Yes, I'm trying to use state = active as a lookup. This is what I have so far basically: $omapi->connect; print "\n\nconnected!\n\n\n"; $lease = $omapi->new_object("lease"); $lease->ip_address("169.229.7.12"); $lease->read; This works fine so I can lookup by ip_address. What I want to do is get a list of leases with states = active. So what I was trying was this: $omapi->connect; print "\n\nconnected!\n\n\n"; $lease = $omapi->new_object("lease"); $lease->ip_address("169.229.7.12"); $lease->state("active"); print "lease created...\n\n"; $lease->read; which gave me the error I noted in my first message. This is the exact set of errors I get: connected! lease created... $ new lease $ set state = 2 obj: lease $ open obj: lease state = 2 $ close can't open object: not implemented obj: lease state = 2 Show quoted text

> obj: <null>

Thanks for the help! Really appreciate it! - Jeff On Tue, Jun 15, 2010 at 3:40 PM, Jan Henning Thorsen via RT < bug-Net-ISC-DHCPd@rt.cpan.org> wrote: Show quoted text

Hi Jan, Also we're trying to do lookup via mac address using this: $omapi->connect; print "\n\nconnected!\n\n\n"; $lease = $omapi->new_object("lease"); $lease->hardware_address("00:e0:81:30:27:d4"); $lease->read; We can do lookups with omshell using a specified mac address but we can't using this perl module. Is there any particular reason for that? Thanks! - Jeff On Tue, Jun 15, 2010 at 6:26 PM, jeff bair <zidanej@gmail.com> wrote: Show quoted text

This will be fixed in 0.07. The reason for this is that it was not documented as "lookup" from http://linux.die.net/man/8/dhcpd Got a better source of documentation? :) Anyway. I did add it. Could you also have a look at the source code and see if any other attributes are lacking the "lookup" action? http://cpansearch.perl.org/src/JHTHORSEN/Net-ISC-DHCPd- 0.05_02/lib/Net/ISC/DHCPd/OMAPI/Lease.pm # please look for all the lines with "omapi_attr ... => (".

I've been testing and googling this issue and it seems like the omshell and/or omapi simply ignores the attribute. What we can do (since this is an abstraction layer:)) is simply to add a post-filter on the retrieved data and force "read()" to return false when the retrieved "state" don't match the requested "state()". I'm not quite sure I like the solution, but I will implement it on request... I will release 0.07 when I get your reply - unless you want more to be included. Fork me at github if you like: http://github.com/jhthorsen/net-isc-dhcpd

The post-filter implementation would be great if possible. It looks like the lookup attributes are fine and thanks for the changes! - Jeff Bair On Thu, Jun 17, 2010 at 11:58 AM, Jan Henning Thorsen via RT < bug-Net-ISC-DHCPd@rt.cpan.org> wrote: Show quoted text

0.07 Fri Jun 18 01:30:15 CEST 2010 - Add (RT58391) OMAPI lookup by hardware_address, even though it does not appear to described in the dhcpd manual (?) Contributor: Jeff Bair - Add (RT58391) post check after OMAPI read() to see if lookup attributes match retrieved data. This is because omapi/omshell seem to have a bug where lease lookup with "state" is ignored. This is subject for change! Contributor: Jeff Bair
