How about ping -b 255.255.255.255 ?

I don't think you can trust pings of the broadcast IP. ================================ On my network: Both ping -b 255.255.255.255 and ping -b 10.0.1.255 only show 5 hosts: === WARNING: pinging broadcast address PING 10.0.1.255 (10.0.1.255) 56(84) bytes of data. 64 bytes from 10.0.1.249: icmp_seq=1 ttl=64 time=0.289 ms 64 bytes from 10.0.1.248: icmp_seq=1 ttl=255 time=0.311 ms (DUP!) 64 bytes from 10.0.1.183: icmp_seq=1 ttl=64 time=1.21 ms (DUP!) 64 bytes from 10.0.1.2: icmp_seq=1 ttl=64 time=1.22 ms (DUP!) 64 bytes from 10.0.1.3: icmp_seq=1 ttl=64 time=2.20 ms (DUP!) === But: fping -g 10.0.1.0/24 -a -s -c 1 -r 1 Reports 24 IPs in use: === 256 targets 24 alive 232 unreachable === which seems a lot more realistic in my office. fyi: the broadcast ping is missing both openSUSE and windows machines at a minimum. Seems to get routers and printers.
