ARP timeout and requests

What is the timeout on dynamic arp entries (ex: created via ping) in
QNX?
Is this timeout configurable?

How can an arp request be generated, like a send_arp ?
Is it in QNX possible to send ar requests via raw sockets as in
Linux?

Thanks!

Approx 20-25 minutes.

Not currently. In the future it will be via sysctl.

Not currently without a custom filter.

You don’t need to write your own “custom” filter. We use nfm-nraw.so
which is available as part of the Networking TDK. Once you load that
you can open /dev/io-net/enX for writing and directly send raw packets
through it. We have successfully ported send_arp using this method.
