A subnet mask 255.255.252.0 will give you 1022 hosts i.e 192.168.0.1 - 192.168.3.254
You may want to use 255.255.248.0 to leave space for statics. You would then have usable hosts from 192.168.0.1 - 192.168.7.254 for a total of 2046

dhcpactiv.sh in the bug tracker that will list all active DHCP leases plus the current arp table on the SME (part of an aging new feature request to add this functionality to server-manager: http://bugs.contribs.org/show_bug.cgi?id=2641)

From a server command prompt:

Code: [Select]

wget -O /usr/local/bin/dhcpactiv.sh http://bugs.contribs.org/attachment.cgi?id=947
chmod 755 /usr/local/bin/dhcpactiv.sh
Now list active leases and currently connected hardware (by arp table) using:

Code: [Select]

dhcpactiv.sh
Or count active dhcp leases using:

Code: [Select]

dhcpactiv.sh |grep -c dhcpd.leases
