Need help with LEASEQUERY..

[Matt Pascoe]

I too would love to do LEASEQUERY from PHP.  I have tried and
been unsuccessful as well.  I've worked a bit with the following code but
have not had time to do any testing with it since it was updated.  You might
give it a test and see if you can get further with it?  check out the
leasequery.php file in the repository.

http://github.com/adinardi/phpdhcp

I also have tried to use the PERL leasequery tool and had trouble getting it
to work.

My goal with leasequery is to simply create a function that I can give a
single IP or a range of IPs (masked or range) and get a list of lease
information from the DHCP server.  I'd prefer not to have to look at
leasefiles but to use the LEASEQUERY method to ask the server directly.

Thanks
