Unlike tracert on windows, traceroute on linux uses UDP packets (by default). For some reason I cannot traceroute anywhere, from a variety of linux boxes, over any of my EX4200s. Not even the office firewall which is an EX switch and dumb Netgear switch away shows up. Yet ICMP traceroutes work fine.
Traditional traceroute uses UDP on incrementing ports for every hop. You can use any sort of packet to implement it - ICMP, TCP SYN, etc. All it takes is the IP packet expiring and you are golden. Vedbex: Traceroute Traceroute or tracert is an online tool that you can use to trace the route a packet take through the routers to arrive to its destination using different protocol like UDP, TCP, ICMP. networking - Why traceroute sends UDP packets and not ICMP
Traceroute Online with Mapping | Tactical Network Testing
According to the Stevens (TCP/IP Illustrated) the traceroute program sends UDP packets to the destination host with an incremental TTL (1, 2, 3, etc) to get the intermediate hops info from the ICMP TTL EXPIRED messages.
Select UDP protocol and the port(s) number(s) into the next window and click Next. Select Allow the connection and hit Next. Select the network type and click Next. Give a name for the rule and click Finish. For ICMP, the quickest way to do it is opening an admin command prompt and typing:
A very powerful tool for diagnosing network problems is traceroute. Traceroute, in its most basic form, allows you to print out a list of all the intermediate routers between two destinations on the Internet. For more details see: Traceroute protocols: ICMP, IP, UDP. There is … MTR (software) - Wikipedia My traceroute, originally named Matt's traceroute (MTR), is a computer program which combines the functions of the traceroute and ping programs in one network diagnostic tool.. MTR probes routers on the route path by limiting the number of hops individual packets may traverse, and listening to responses of their expiry. It will regularly repeat this process, usually once per second, and keep
