Unable to ping 127.0.0.1 after cleaing routing table at Windows 7.

OS/Windows 2015. 2. 26. 19:14

When clearing routing table with "route -f", then 

  • Fail to ping 127.0.0.1 with general failure
  • Unable to use debugger at Eclipse: JDWP Transport dt_socket failed to initialize
My solution was
  1. Disable all NICs.
  2. Execute "route -f" again.
  3. Enable all NICs and input necessary information such as gate way.
  4. Reboot computer.
  5. Check 127.0.0.1 with "route print" command.
  6. Execute "ping 127.0.0.1" and confirm it works OK.
