Testing network connectivity with the ping command (1003486)
Purpose
For troubleshooting purposes, it may be necessary to test network connectivity between different components of your network. This article provides you with the steps to perform a ping test on your network from Windows, Linux, and ESX/ESXi hosts.
Resolution
Testing with Ping from a Windows Host
To initiate a ping test from a Windows host:
Click Start > Run, type cmd, then click OK.
At the command prompt window, run:
ping <server>
Where <server> is the hostname or IP address of the server that you want to ping.
Press Enter.
A successful ping response is similar to:
C:\>ping server
Pinging server with 32 bytes of data:
Reply from server: bytes=32 time<1ms TTL=64 Reply from server: bytes=32 time<1ms TTL=64 Reply from server: bytes=32 time<1ms TTL=64 Reply from server: bytes=32 time<1ms TTL=64
Ping statistics for server: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms
Ping statistics for server: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
C:\>
Note: If you do not see a response when pinging by the hostname of the server, initiate a ping to the IP address. Initiating a ping to the IP address allows you to determine if the problem is a result of an issue with hostname resolution.
Testing with Ping from a Linux Host
To initiate a ping test from a Linux host:
Open a Terminal to the Linux command shell.
In the command shell window, type ping <server>
Where<server>is the hostname or IP address of the server that you want to ping
Press Enter.
Note: To stop the ping, press Ctrl + C.
A successful ping response is similar to:
[root@server]$ ping server PING server (10.0.0.1) 56(84) bytes of data. 64 bytes from server (10.0.0.1): icmp_seq=0 ttl=64 time=0.025 ms 64 bytes from server (10.0.0.1): icmp_seq=1 ttl=64 time=0.029 ms 64 bytes from server (10.0.0.1): icmp_seq=2 ttl=64 time=0.032 ms 64 bytes from server (10.0.0.1): icmp_seq=3 ttl=64 time=0.028 ms
[root@server]$ ping server PING server (10.0.0.1) 56(84) bytes of data.
--- server ping statistics --- 4 packets transmitted, 0 received, 100% packet loss, time 3017ms [root@server]$
Note: If you do not see a response when pinging by the hostname of the server, initiate a ping to the IP address. Initiating a ping to the IP address allows you to determine if the problem is a result of an issue with hostname resolution.
Testing with Ping from an ESX/ESXi host:
To initiate a ping test from the console of an ESX/ESXi host:
Where<server> is the hostname or IP address of the server that you want to ping
Press Enter.
Note: To stop the ping, press Ctrl + C.
A successful ping response is similar to:
[root@server]$ ping server PING server (10.0.0.1) 56(84) bytes of data. 64 bytes from server (10.0.0.1): icmp_seq=0 ttl=64 time=0.025 ms 64 bytes from server (10.0.0.1): icmp_seq=1 ttl=64 time=0.029 ms 64 bytes from server (10.0.0.1): icmp_seq=2 ttl=64 time=0.032 ms 64 bytes from server (10.0.0.1): icmp_seq=3 ttl=64 time=0.028 ms
[root@server]$ ping server PING server (10.0.0.1) 56(84) bytes of data.
--- server ping statistics --- 4 packets transmitted, 0 received, 100% packet loss, time 3017ms [root@server]$
Note: If you do not see a response when pinging by the hostname of the server, initiate a ping to the IP address. Initiating a ping to the IP address allows you to determine if the problem is a result of an issue with hostname resolution.
