On the windows issue, the command “route print”. On Linux issue, “route -n” command as a root user to see the current routing table. SOLUTION: Identify the IP addresses that are repeating and causing the loop. It will result in a ‘TTL expired in transit’ error. TTL expired in transit: When there is a heavy loop in routing the packet to the destination, TTL will expire.Modify the local route table or notify the router administrator. SOLUTION: Validate whether the destination host is up and running. Ping statistics for 192.168.0.0: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss) Reply from 192.168.0.102: Destination host unreachable. Destination Host Unreachable: When the host you are trying to reach is down or unavailable on the network, then ‘Destination Host Unreachable’ error will be returned.Įxample: ping 192.168.0.0 Pinging 192.168.0.0 with 32 bytes of data: Reply from 192.168.0.102: Destination host unreachable.Verify whether DNS servers are available/reachable from your host. SOLUTION: Verify the hostname that is passed to the ping command. Ping Request Could Not Find Host: When the IP address can not be determined from the hostname passed to the ping command, you will experience this error.Įxample: ping Ping request could not find host.SOLUTION: Increase the wait time using the ping -w switch.

Request Timed Out: If there is no response from the host due to heavy network traffic OR if there is a failure of ARP request packet filtering OR if there is an error in the router, then the ping request will timeout.Įxample: ping gceasy.io Pinging gceasy.io with 32 bytes of data: Request timed out.

Following table summarizes the ping command’s default TTL value for the popular Operating systems: Ping command’s TTL (Time To Live) Values differ from Operating system to Operating system. Maximum : It is a maximum time to get a response in milliseconds What is the ping’s default TTL? Minimum : It is a minimum time to get a response in millisecondsĪverage : It is a average time to get response in milliseconds Packets Lost: Number of packets failed to reach the destination. Packets Received: Number of times packet has been received from the destination to the host.

Packets Sent: Number of times packet has been sent from the host to destination. Because of this packets are designed with an expiration called a time-to-live. When a packet is sent across the internet, there is a chance that packet passes from the router and the packets will be sent until the user interrupts this command. TTL(Time To Live): is the amount of time or “hops” and it can vary from 0 to 255 depending upon the Host Operating System.It is a time taken by the packet to reach from Source to Destination and reported back to the source When the above command is issued, the following message will be printed in the console: Pinging with 32 bytes of data: Reply from 195.201.17.137: bytes=32 time=217ms TTL=45 Reply from 195.201.17.137: bytes=32 time=185ms TTL=45 Reply from 195.201.17.137: bytes=32 time=188ms TTL=45 Reply from 195.201.17.137: bytes=32 time=196ms TTL=45 Ping statistics for 195.201.17.137: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 185ms, Maximum = 217ms, Average = 196ms Here is how you can invoke this command: ping If connectivity is successful then overall round trip time is printed, if not reason for failure such as packet loss, timeout, connectivity errors,… are printed. Ping command sends a 32 bytes ICMP (Internet Control Message Protocol) packet from “Host A” (Source) to “Host B” (Destination) and waits for the “Host B” to be responded with a 32 bytes packet to “Host A”.
