ARP Ping and ICMP in Ruby?

Ruby

What would I have to do in order to be able to send an ARP Ping or a
regular ICMP_ECHO_REQUEST in Ruby? Is it possible?

require ‘ping’

Ping.pingecho(‘example.com’)

or

system(‘ping -c1 www.example.com’)

regular ICMP_ECHO_REQUEST in Ruby? Is it possible?
Posted via http://www.ruby-forum.com/.

pingecho() uses a TCP echo (not an ICMP echo) to determine if the
remote host is reachable. This is usually adequate to tell that a
remote
host is available to rsh(1), ftp(1), or telnet(1) to.

So the standard library may be sufficient, but not necessarily so.

In addition to the above, you can also try the net/ping from rubyforge,
or
possibly even rubyforger to craft your own ARP or ICMP packets.

HTH,

Felix

require ‘ping’

Ping.pingecho(‘example.com’)

Unfortunately, this isn’t a ‘ICMP_ECHO_REQUEST’, it’s an attempt to
connect
to the remote machine on the ‘echo’ port. If the connection is refused
or
allowed, pingecho() returns true. If it times out, or otherwise errors,
it returns false. Either way, it’s not ICMP if you need ICMP.

or

system(‘ping -c1 www.example.com’)

Shelling out to a ping command is probably a bad idea for portability
reasons.

If a TCP connection test works for you then go with the stdlib Ping
library.
If it doesn’t, you might look into RubyInline or writing a simple C
extension for basic ICMP requests.

Cheers!

require ‘net/ping’
include Net

icmp = Ping::ICMP.new(‘foo.com’)

if icmp.ping?

Successful

else

Failed

end

gem install net-ping
