[bash]: IP Discover Script

I've got a problem with an old router. This router has DHCP disabled and the hardware reset won't work.
So I've got to found the correct IP address by trying each one (192.169.x.y ones). I've thought on a shell script.
Did anyone have an idea?

My router is 192.168.11.1. So you could scan the network w/ nmap something like so:

Code: Select all

nmap 192.168.11.0/24

That shows you every i.p. on the subnet.

so , do you have an idea how this would work in a bash-script with a for-loop to "scan" across 192.168.0.0 until 192.168.255.0 networks?

if you know its in 192.168 just set the subnet mask on your interface to 255.255.0.0 and then do nmap 192.168.0.0/16

it'll take a while though

also if the hardware reset isn't working then it seems pretty likely that the unit may simply be dead
