comment Can someone explain nginx conditional flags? (-f, -d, -e, etc)
The docs don't say much beyond what you pasted, but these appear to be modeled after the UNIX/POSIX "test" utility (man test).

comment Why not assign the hostname to the loopback address in /etc/hosts?
Do you know of any real-world cases where "tell the other guy your hostname" is a problem? Wouldn't the socket reveal the addresses at each end? Wouldn't multhoming / multiple addresses cause problems in this case as well?

Given that the server has been hacked, "forensically analyze a hostile binary" would be my guess.

comment Is there any possible way in which unicast packet from one machine sent to two machines?
Unless a NIC is in promiscuous mode it will drop any unicast packet not destined for it. In a normal, default environment a unicast packet from A to B which happens to be flooded out C's port will be dropped by C's NIC.
