If no response is received within the specified time, the check will be considered as failed. ![]() This is the time during which the program waits for a response from the host. But, the more packets you send, the longer the host is checked. You can set the number of packets to more than one to eliminate the possibility of false host state detection if one packet is lost. This is the number of ICMP ping packets that the program will send to the remote host in one check. Configure the ping parameters, or leave them by default: Select the ICMP ping availability type of the check.ģ. Click the menu item Checks -> Add check.Ģ. If you want to add a new ICMP ping check, then follow these steps in the program:ġ. In other words, when you are running the program for the first time after the installation and scanning the network, you get a ready-made monitoring base with your hosts that are already being pinged. These checks are also generated for all found hosts during the network scan. When a new host is created in the program, an ICMP ping check is assigned to it by default. Iptables -I OUTPUT -p icmp -icmp-type echo-reply -j ACCEPTġ0-Strike Network Monitor (Pro) allows you to monitor the status of hosts using the ICMP protocol. Iptables -I INPUT -p icmp -icmp-type echo-request -j ACCEPT If they were disabled, then the commands executed as root will help to enable them again: For Linux:īy default, all Linux distributions allow incoming ICMP requests as well. These commands create a firewall rule that allows incoming ICMP requests. Set-NetFirewallRule -Name FPS-ICMP-ERQ-In -Enabled True -Profile Any -Action Allow Instead of the command line, you can start PowerShell and run the command there: Netsh advfirewall firewall add rule name="ICMP Allow“ protocol=icmpv4:8,any dir=in action=allow Run a command line with administrator rights.To resolve them, follow these steps: For Windows: However, there may be situations when ICMP is prohibited in the system (blocked by the firewall). It is included in all modern operating systems. And the ping command is one of the main diagnostic tools in TCP/IP networks. This is the basic mechanism for agentless monitoring of network nodes in many monitoring programs. But despite this, ping remains the fastest and most popular way to assess the availability of a remote host over the network. ![]() For example, a mail server can respond to ICMP requests, but the email service will not work. Another disadvantage of this method of checking the health of a host is that the ICMP ping does not make it possible to assess the state of running services.
