Dear Talha,
It looks like there is no lo0 network interface on your system
or Polygraph code that manages IP aliases does not work well on your
OS. What operating system are you using?
If you are using Linux, please try changing
'lo0::10.101...' in your PGL file to 'lo::10.101...'
Linux and Solaris call their loopback interfaces differently
from BSD OSes.
Let me know if you are still stuck.
Alex.
