Hi I want to ping test about “PC → target”, but I don’t konw what something is wrong.
The current situation is below.
ping : PC -> Target(localhost) (X)
ping : Target(localhost) -> Target(localhost) (O)
ping : Target(localhost) -> PC (X)
arping : Target(localhost) -> Target(localhost) (X)
arping : Target(localhost) -> PC (O)
As I checked tcpdump log, it appears as below, but I don’t know where to correct it.
connect: Network is unreachable
14:04:16.334495 IP localhost > localhost: ICMP localhost udp port domain unreachable, length 82
As can be seen in the target service list, ipables has already been turned off.
