Hi, i need a way to know what IPs are active on my LAN. Ive been told to ping the broadcast address, but its not working. Any Idea?

Have a look at fping (its included on the SuSE distribution). It allows you to specify a range of IP addresses to ping on the command line. The only thing to be aware of is that it must be run as root.
Both fping and 'ping -b' must be run as root. 'nmap -sP <IP-range>' can be run as an ordinary user.
I was able to run ping -b as root and a regular user. (??) Oddly, nothing on my network responds. I know the file server(99), the router(12), and the network printer (101) are all turned on. Direct pings work.
