You can do it with shell script: while read line; do ping -c1 $line || echo $line >> newlist done < iplist This will read in IP from a list and spit out IP's not found to another list. If you need to generate lists you can use this: class_c="127.0.0";i=0 while [ i -le 255 ];. do echo "$class_c.$i" >> iplist i=$(($i+1)) done It's cheap, but it works... -Dan

Hi,

I'm looking for a pinger that'll ping a list or range of IP address and

if it finds a IP address then remove it from the list.

I'm working in a static IP allocation nation and I need to weed out a few

of the redundant IP's.

I thought that maybe fping might be what I'm looking for, but its not in Herr Grimmers' ftp site.

Any help appreciated.

Cheers,

Mal.
