Next, ping the server's network IP address from itself. This should get you exactly the same results as pinging 127.0.0.1:
server% ping 192.168.236.86

If this works on the server, repeat it for the client. Otherwise:

If
ping
network_ip fails on either the server or client, but ping 127.0.0.1 works on that machine, you have a TCP/IP problem that is specific to the Ethernet network interface card on the computer. Check with the documentation for the network card or the host operating system to determine how to correctly configure it. However, be aware that on some operating systems, the
ping command appears to work even if the network is disconnected, so this test doesn't always diagnose all hardware problems.
