Hi @all
How can I find out the mac address from the default gateway with a ruby
script?
Does exist any methods to read it out? The script runs on a linux
distribution...
thanks for your comment!

I don't know if any methods, exist, but you could hack it up if you
have the 'ip' package installed on your system, ie. 'ip show route'
doesn't say the command wasn't found.
Then you can try:
# get your gateway IP address
gateway = `ip route
show`.match(/default.*/)[0].match(/\d\d?\d?\.\d\d?\d?\.\d\d?\d?\.\d\d?\d?/)[0]
# get the mac address for the gateway
mac_address = `ip neigh
show`.match(/#{gateway}.*/)[0].match(/..:..:..:..:..:../)[0]

this may not help you directly, but:
cfp:~ > ruby -r macaddr -e' p Mac.addr '
"00:17:f2:d5:c1:ec"
gem install macaddr
regards.

If you know the IP address of the gateway, then parse the output of
the 'arp -n <IP>' command. It's reasonably portable and easy to
parse.

Of course I meant if 'ip route show' doesn't say the command wasn't found.

I don't know if any methods, exist, but you could hack it up if you

Then you can try:# get your gateway IP address
gateway = `ip route
show`.match(/default.*/)[0].match(/\d\d?\d?\.\d\d?\d?\.\d\d?\d?\.\d\d?\d?/)
[0]
or .match(/((?:\d{1,3}\.){3}(?:\d{1,3}))/)
(group (3 groups of 1-3 decimals followed by a period) with (a group of 1-3
decimals))
# get the mac address for the gateway
mac_address = `ip neigh
show`.match(/#{gateway}.*/)[0].match(/..:..:..:..:..:../)[0]
this could also be more correct:
/((?:[\da-f]{2}:){5})(?:[\da-f]{2}))/
So it doesn't match *any character*, but instead valid MAC addresses.
