Show the Number of Active LAN Clients



  • Is there anywhere in PFsense that will show me the number of clients on my network?  I can hand count them from DHCP leases, but wondered if there is a summary somewhere.  I was thinking maybe there is a command line that will return the the number.

    Thanks,

    Jerold



  • The ARP table has a list of static & dynamic clients that have been seen recently, but it's not guaranteed to be complete list at any given moment in time, and there is no total.

    Diagnostics - ARP Table



  • Use nmap (on "something")

    nmap -sP <ip-net>/ <netmask>Ie. nmap 192.168.1.0/24

    /Bingo</netmask></ip-net>



  • Internal:

    • The ARP table as named above
    • Squid & SARG perhaps

    External:

    • CentOS and NAGIOS2
    • TclMon on an APU, NUC or other small device
    • On a small external device such the RaspBerry PI or the netgate MinnowBoard Turbot series and a Linux or FreeBSD
      OS on it with CACTI and MRTG.
