Ping not working on Ping Redirect (Type 5)

[Kr0san89]

Hello,

i found in networks where the GW sends an ICMP Typ5 Message (Redirect) (https://www.iana.org/assignments/icmp-parameters/icmp-parameters.xhtml#icmp-parameters-codes-5) this module just returns an error.

Ping error RedirectReceivedError: Redirect received (source=<gw ip>)

I did the same ping with the linux ping tool and this returns
ping -v <ip> PING <ip> (<ip>) 56(84) Bytes Data. From<gw ip> icmp_seq=1 Host redirect(New nexthop: < other router ip>) 64 Bytes from <ip>: icmp_seq=1 ttl=63 Zeit=26.3 ms 64 Bytes from <ip>: icmp_seq=2 ttl=63 Zeit=9.43 ms

Not completly sure how to fix this i assume on type 5 the node-net-ping package shouldn't error but rather keep going?
L 306
else if (req.type == 5) { req.callback (new RedirectReceivedError (source), req.target, req.sent, new Date ()); }
The error is quite anoying as all the ips are not "pingable"

I would contribute a change, if someone knows getting rid of the error is sufficient (not so in the details of ping)

thanks
