looks like arp is unreliable for a canonical list of plugged in ip's. Curious about what would work.
"nmap -sP 22 192.168.0.0/24" should do it
%nmap -sP 22 192.168.0.0/24
Starting nmap V. 3.00 ( www.insecure.org/nmap/ ) Target host specification is illegal. QUITTING! %
I don't understand the man page though so assume it's me, not nmap.
ping 192.168.0.255
%ping 192.168.0.255 PING 192.168.0.255 (192.168.0.255): 56 data bytes 64 bytes from 192.168.0.3: icmp_seq=0 ttl=255 time=0.964 ms 64 bytes from 192.168.0.160: icmp_seq=0 ttl=64 time=1.359 ms (DUP!) ^C
Hmm, since there are five nodes on my class c network this didn't do the trick either.
I wrote a quick perl script that I think works but so slowly that it's impractical:
%perl -e 'for(0..255) {$ip = "192.168.0.$_";$ping = `ping -c1 $ip`;print "$ip\n" if $ping =~ /64 bytes from/}'
192.168.0.0
192.168.0.1
192.168.0.3
