Ping any device or server. As a simplified implementation of scripting engines, users can arrange for a certain command or program to be executed in the event of connection loss, resume and so on. Used in combination with the other powerful tool sets, the EMCO Ping Monitor is often ahead of the pack for the sheer functionality it provides.
Essentially, a Twinge flood is the same as a Ping flood and the solutions to protect a network from it are the same as for the main category of DDoS attack via ICMP: turn off ICMP, install a web application firewall or a stateful firewall, or install an intrusion detection system.
A DNS resolution function shows the hostname for a requested IP address if it can find it. The absence of a hostname for a record should raise alarms if that IP address was contactable because either your DNS records are out of date or you have an intruder on the network.
A ping involves a packet of data being sent to a specific IP address (known as an echo request), if the device is active and healthy it will respond (known as an echo reply) and likely provide additional information that might help diagnose any network issues.
If that gets through, you shouldn't have any problems with your connections to the destination host that you sent the test packet to. Bookmarks If the transmission provokes an ICMP error, then you would just try the test repeatedly, reducing the packet length each time.
Knowing that critical systems and services are working is a fundamental aspect of the network administrator's job, and Ping Monitoring is the most powerful tool for doing so. The sheer simplicity of the command is rather profound, especially considering the amount of information can be garnered from it.
Using this technique gives you a clear perspective of the health of your key devices.PagerDuty's platform for real-time operations allows you to integrate your ping monitoring tools from all different areas of your tech stack and centralize them into one single point of ingestion, enabling full visibility into the health of your network, servers, and other pieces of infrastructure.
