Start/stop DHCP-server via shell

[PreLo]

Hello,

I am unable to manually start/stop the DHCP-server via shell command.
Could somebody please point me into the right direction?

Many thanks in advance!

ok ok - your neglect tells me to be more elaborate. :-)

There really is some sense behind that question.

At first I simply wanted to start and stop the DHCP-Server via script, but as I have added another NIC to my pfsense it would be way better if I could change the configuration of the dhcpd to stop listening on one interface. That way, I can keep using DHCP on one interface and turn it off on the other.

The following basic steps are what I have in mind for the script:
1.DHCP-config A is loaded, DHCP is running.
2. Script stops DHCP-server, checks for configuration.
3. Script detects config A, changes to config B
4. Script restarts DHCP-server.
The script would then run as a cronjob.

I am not sure if this can be done - any help really is appreciated.
The thing is, that I have been unable to find out how pfsense starts and stops the DHCP-Server although I have tried and researched quite a bit and even asked some friends that are way more unix-skilled than I am.

Many thanks in advance.

this is wat pfsense use to start the dhcpd server:
/usr/local/sbin/dhcpd -user dhcpd -group _dhcp -chroot /var/dhcpd -cf /var/dhcpd/etc/dhcpd.conf vr0
