Within the Message Queue in Kerio Connect Webadmin, you see emails with the status вЂњ 4.4.1 Cannot connect to host.вЂќ The warning log shows dozens of entries similar to this: вЂњ Cannot connect to SMTP server. It was inspired by Dave MillsвЂ™ Fuzzball program that measured path latency on the PDP-11.You cannot send emails to a particular recipient, domain, or mail server. Mike Muuss created the first version of the program offering this command at what is now the US Army Research Laboratory in 1983. Most operating systems include some version of the ping command. By knowing the speed of sound in water, the sonar can determine the distance to the object on which the sound waves bounced. The sonar sends out a ping sound and measures the time it takes to get an echo. The term ping originates with sonar echolocation on submarines.

Sometimes, responses come directly from a router, so you get an answer even if the server behind it is unavailable. For example, its web or email server might be down (or the host might not offer these services at all). CaveatsДЄ host that responds to a ping is functioning and available, but this doesnвЂ™t provide you with any information about the services that are running on the server. If you receive quick responses from the Online Ping tool, while pings from your local computer are problematic, it might indicate a local problem with either your connection or the way the host treats your location. Furthermore, it might be possible for Network Tools to reach the host, while your computer might not be able to reach the host (or vice versa). It may not be a good indicator of how fast your local machine can connect to and communicate with the host. The round-trip time presented to you by the Online Ping tool tells you how quickly Network Tools can connect to the host. To check the availability of resources on your network, you will need a local ping tool. Local PingsД«ecause the Online Ping tool runs using Network ToolsвЂ™ infrastructure and not on your local machine, you cannot use it to test internal addresses on your local network. Some hosts may accept requests from a limited range of IP Addresses (such as those originating in its own country) and may not respond to requests from the Online Ping tool. If a host occasionally responds while timing out in other circumstances, it may be utilizing a poor connection or be handling a high number of requests for which it lacks the resources to process efficiently. As such, the lack of a response doesnвЂ™t conclusively prove that a host is unavailable (though it may be unavailable to communicate with your machine). In general, a publicly-accessible server should always respond, whereas the firewalls on many other types of machines block pings by default. Some firewalls block echo requests to prevent distributed denial of service (DDoS) attacks, to reduce the visibility of the host, or even by mistake. However, this may not always be the case.

Per RFC 1122, вЂњRequirements for Internet Hosts,вЂќ each host must send an echo reply when pinged. The tool sends an echo request packet to the host and listens for an echo reply packet.

As such, any functioning host on the internet should respond to the pings sent by the tool. The Online Ping tool uses the Internet Control Message Protocol (ICMP), which is an integral part of the Internet Protocol (IP). As such, you cannot rely on the responses to provide you with consistent, trustworthy information. You can perform a broadcast (multiple-IP address) ping (eg, 104.24.255.255), but the hosts covered are not required to respond.

One common error code is 1214 (transmit failed) when pinging an unreachable or non-existent host.

A valid response, including a set of times, for a different server.

An error message (eg, CouldnвЂ™t resolve host name).

If you provide a non-existent domain name, the results can be unpredictable. If this is the case, youвЂ™ll notice that it will take slightly longer for the command to complete. If the destination is reachable, but the server doesnвЂ™t respond, you will receive a Timed Out response. When done, the tool will present you with the round-trip time (in milliseconds) for each ping, as well as the overall average time. Online Ping sends a packet to the destination and waits for a response. To help diagnose intermittent issues, we recommend running the tool several times (with tests separated by at least a few minutes). If youвЂ™re having issues with a domain name or IP address, the Online Ping tool can determine if the site is live and if it is having problems. If you provide a Base-10 IP address, check the Convert Base-10 to IP box.
