[ale] Hijacking my own IP

[Chris Fowler]

Someone else screwed up assigning IPs.  I'm waiting for an IP change.  While waiting, I want my connection to remain up.

I have a HP printer and Linux device with the same IP address on a network.  I have no control over the printer.  I'm trying to figure out how to effectively use arping to "hijack" my own IP on this subnet.

My remote connection to the device is dropped at random times.  I'm guessing maybe someone is printing. This causes the firewall to update its arp cache, send a packet to the HP instead of my device, and I get a RST on my end because the HP said, "I have no clue what this is."

I guess some background on why the printer and linux device has to use the same address might clear it up a bit for us.
