Shell/Perl Script to edit dhcpd.conf

Hi,
I need to get a script together to edit the dhcp service configuration file dhcpd.conf.

Mac addresses are defined in classes ex.
class "HOST1" { match if substring (hardware, 1,18)=00:11:11:FF:FF:FF;}
class "HOST2" ...
class "HOST3" ...
...

followed by allow or deny statements:
deny members of "HOST1";
allow members of "HOST2";
...
...

The script should search for the MAC address entered by the user and if found should deny that class by changing allow to deny in the statement for that class and/or deleting the class.
If not found it should create a class with the given MAC address and add a deny statement for that class in the above given format.

I would appreciate any ideas or help...

Thanks

SB

NAME
ftphosts - FTP Server individual user host access file SYNOPSIS
/etc/ftpd/ftphosts DESCRIPTION
The ftphosts file is used to allow or deny access to accounts from specified hosts. The following access capabilities are supported: allow username addrglob [addrglob...] Only allow users to login as username from host(s) that match addrglob. deny username addrglob [addrglob...] Do not allow users to login as username from host(s) that match addrglob. A username of * matches all users. A username of anonymous or ftp specifies the anonymous user. addrglob is a regular expression that is matched against hostnames or IP addresses. addrglob may also be in the form address:netmask or address/CIDR, or be the name of a file that starts with a slash ('/') and contains additional address globs. An exclamation mark (`!') placed before the addrglob negates the test. The first allow or deny entry in the ftphosts file that matches a username and host is used. If no entry exists for a username, then access is allowed. Otherwise, a matching allow entry is required to permit access. EXAMPLES
You can use the following ftphosts file to allow anonymous access from any host except those on the class A network 10, with the exception of 10.0.0.* IP addresses, which are allowed access: allow ftp 10.0.0.* deny ftp 10.*.*.* allow ftp * 10.0.0.* can be written as 10.0.0.0:255.255.255.0 or 10.0.0.0/24.
