When a traceroute command is executed, generally it will go for a maximum of 30 hops. w : Set the time (in seconds) to wait for a response to a probe. q : Sets the number of UDP packets per hop. m : Specifies the maximum number of hops (max Time-To-Live value). You can check where traceroute is located using the command : which traceroute So the traceroute command can be also run as /usr/sbin/traceroute server-name In general, traceroute can be found in /usr/sbin. We will be discussing in detail about traceroute in IPv4, Unix environment In Windows machines : tracert server-name (tracert ) In Unix machines : traceroute server-name (traceroute ) The optional packet length is the total size of the probing packet (default 60 bytes for IPv4 and 80 for IPv6). The only required parameter is the name or IP address of the destination host. Routers will discard a packet when the TTL has reached zero, returning an ICMP error message Code 11 (ICMP Time Exceeded) to the sender. TTL refers to how many routers your packet can go through before its expires. It passes through a series of intermediate routers, which involves a TTL (Time-to-Live) value. When we initiate Traceroute, it sends a sequence of Internet Control Message Protocol (ICMP) packets addressed to a destination host. It always shows you how your machine is connected to ISP and ISP to the rest of the network, collectively the connection between your end and server. It can help you in analyzing why the connections from your end to a server is poor, and can often help you to spot what exactly is the problem. Traceroute is the program that shows you the route over the network between two systems, listing all the intermediate routers a connection must pass through to get to its destination. How many times have you been asked for providing a ‘traceroute’ output by your Hosting provider, or if you are an admin working with a hosting provider, how many times you’ve asked for the results of traceroute to your client ? The traceroute output explained here,
