ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available in a wide range of operating systems – including most embedded network administration software.
The related ping utility is implemented using the ICMP echo request and echo reply messages. ICMP uses the basic support of IP as if it were a higher-level protocol, however, ICMP is actually an integral part of IP.
nslookup, used to query a DNS server for DNS data (deprecated on Unix systems in favour of host and dig; still the preferred tool on Microsoft Windows systems). vnStat, useful command to monitor network traffic from the console. vnstat allows to keep the traffic information in a log system to be analyzed by third party tools.
Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.
The name is a play on the word ping, another computer network administration utility. Because ICMP can be used to identify the operating system of a remote machine, [1] [2] it is sometimes blocked. [3] [4] If ICMP is blocked, ping cannot be used to identify if the service is responding. Publicly available services must keep their relevant TCP ...
The ping utility measures the RTT, that is, the time to go and come back to a host. Half the RTT is often used as an approximation of OWD but this assumes that the forward and back paths are the same in terms of congestion, number of hops, or quality of service (QoS). This is not always a good assumption.
A well-known example of this is the ping utility. [7] ICMP responses will be allowed back through the firewall. In some scenarios, UDP communication can use ICMP to provide information about the state of the session so ICMP responses related to a UDP session will also be allowed back through.
The PathPing command is a command-line network utility included in Windows NT operating systems since Windows 2000 that combines the functionality of ping with that of tracert. [1] It is used to locate spots that have network latency and network loss. [2] [3]
