mtr a network diagnostic tool

mtr [ hvrctglspniu46] [ help] [ version] [ report] [ report wide] [ report cycles COUNT] [ curses] [ split] [ raw] [ no dns] [ gtk]
[ address IP.ADD.RE.SS] [ interval SECONDS] [ psize BYTES | s BYTES] HOSTNAME [PACKETSIZE]

mtr combines the functionality of the traceroute and ping programs in a single network diagnostic tool.

As mtr starts, it investigates the network connection between the host mtr runs on and HOSTNAME. by sending packets with purposly low TTLs. It continues to
send packets with low TTL, noting the response time of the intervening routers. This allows mtr to print the response percentage and response times of the
internet route to HOSTNAME. A sudden increase in packetloss or response time is often an indication of a bad (or simply overloaded) link.


Print the summary of command line argument options.


Print the installed version of mtr.


This option puts mtr into report mode. When in this mode, mtr will run for the number of cycles specified by the c option, and then print statistics
and exit.

This mode is useful for generating statistics about network quality. Note that each running instance of mtr generates a significant amount of network
traffic. Using mtr to measure the quality of your network may result in decreased network performance.


report wide
This option puts mtr into wide report mode. When in this mode, mtr will not cut hostnames in the report.


report cycles COUNT
Use this option to set the number of pings sent to determine both the machines on the network and the reliability of those machines. Each cycle lasts
one second.


psize BYTES

These options or a trailing PACKETSIZE on the commandline sets the packet size used for probing. It is in bytes inclusive IP and ICMP headers

If set to a negative number, every iteration will use a different, random packetsize upto that number.


Use this option to force mtr to use the curses based terminal interface (if available).


no dns
Use this option to force mtr to display numeric IP numbers and not try to resolve the host names.

o fields order

order fields order
Use this option to specify the fields and their order when loading mtr.
Example: o "LSD NBAW"


Use this option to force mtr to use the GTK+ based X11 window interface (if available). GTK+ must have been available on the system when mtr was
built for this to work. See the GTK+ web page at for more information about GTK+.


Use this option to set mtr to spit out a format that is suitable for a split user interface.


Use this option to tell mtr to use the raw output format. This format is better suited for archival of the measurement results. It could be parsed to
be presented into any of the other display methods.


address IP.ADD.RE.SS
Use this option to bind outgoing packets' socket to specific interface, so that any packet will be sent through this interface. NOTE that this option
doesn't apply to DNS requests (which could be and could not be what you want).


interval SECONDS
Use this option to specify the positive number of seconds between ICMP ECHO requests. The default value for this parameter is one second.

Use UDP datagrams instead of ICMP ECHO.

Use IPv4 only.

Use IPv6 only.

Some modern routers give a lower priority to ICMP ECHO packets than to other network traffic. Consequently, the reliability of these routers reported by mtr
will be significantly lower than the actual reliability of these routers.
