dhcpcd-discuss

Hello,

I have a device running dhcpcd. When I remove the router connection it
acquires a 169.x.x.x address automatically. But this works mostly when I
disconnect my PC running Ubuntu 16.04 LTS from the network. I'm using this
PC to develop and deploy firmware to the device.
When the PC is connected dhcpcd mostly fails after this line -

          eth0: probing for an IPv4LL address

and ends up in segmentation fault.
However when I use avahi the eth0:avahi adapter successfully acquires
169.x.x.x address even when my PC is connected.

From the man page I could get below information but it is not sufficent for
me to pin-point the cause for the failure -
"

When using IPv4LL, *dhcpcd* nearly always succeeds and returns an exit code
     of 0.  In the rare case it fails, it normally means that there is a
     reverse ARP proxy installed which always defeats IPv4LL probing.
"

I found that my PC has RARP installed but it is not running in my process
list.
The command I used to find this is "ps -ef|grep rarp"

Can you please enlighen me on possible causes for this?

Thanks and regards,
Shreesha
