Yep... Ran into some issues this morning also and looking into it.bizziebis wrote:I've tried your modified script and it seems to work half for me.
When I run 'sudo arp -n' I get an arp table which looks cached. It doesn't change when I remove a device from my wifi network.
The table does update after I run 'sudo arp-scan 10.0.0.0/24'.
Are you sure your table does get updated on it's own by using only 'sudo arp -n' ?
Code: Select all
macaddr = {}
data = assert(io.popen('arp -n'))
for line in data:lines() do
ip = string.match(line, "172%.16%.176%.%d+")
mac = string.match(line, "%x%x:%x%x:%x%x:%x%x:%x%x:%x%x")
if (ip ~= nil and mac ~= nil) then
macaddr[mac] = ip
end
end

Are you using something like fping -c 1 -g 172.16.176.0/24
It's possible that this does the same ping -b -c1 172.16.176.255
Anyhow I've taken the liberty of trying to implement the Python script directly in Lua.
So far I'm capturing the active arp entries in a table to get the current IP address for each MAC address.
Code: Select all
macaddr = {} data = assert(io.popen('arp -n')) for line in data:lines() do ip = string.match(line, "172%.16%.176%.%d+") mac = string.match(line, "%x%x:%x%x:%x%x:%x%x:%x%x:%x%x") if (ip ~= nil and mac ~= nil) then macaddr[mac] = ip end end data:close()
