Our system will then determine how long it takes to get a response from your selected Target IP address. The default ping tool that comes with Ubuntu Linux is used, and the results are parsed and displayed in the table.įive packets are sent from our server in Newark (USA).

Network Firewalls, such as commercial Cisco and Checkpoint products can do this as can local firewalls such as your local Windows Firewall or a local Linux firewall using IP Tables. No response from Pingįirewalls and routers can be configured to block ICMP request and response so you will sometimes find a system does not respond to ping even though the system is up and running. A ping uses a type of packet known as ICMP, commonly known as ICMP request and ICMP reply. It does not matter if you are using Solaris, Windows, FreeBSD or Ubuntu Linux ping is ubiquitous.
Ping tools are installed by default in most operating systems. Ping is a network troubleshooting tool that displays the response time between two Internet (or IP) addresses. 128 Microsoft Windows (from Windows XP onwards).64 Linux or *nix based operating system.Your actual result will be lower than the listed value as the TTL will decrement on each hop along the path. This can mean that gateway or NAT devices, such as firewalls and routers, may be the one responding to the Ping.įor example you could ping a Microsoft IIS web server, however, if there is a firewall or load balancer in front of it with a *nix based operating system you will receive a TTL of 64 rather than the expected 128. Of course, there are many other possible values and devices, however, this can be a quick way to determine what the device is that is responding to your Ping request. Generally, Linux, Windows, and Cisco routers have differing values. The starting TTL varies depending on the operating system. These come from the system that you are sending your ICMP request packets to and can be used to perform a limited operating system detection check. In a Ping response, there is a TTL or Time to Live value. Here is a bit of useful information that you can impress your friends with.
