Description Pekka Savola 2002-08-19 11:23:20 UTC
Traceroute implements -t switch which can be used to set type-of-service byte in
the datagrams.

Certain routers are configured to change the value of TOS (mainly to implement
differentiated services model).

It's useful to know if this is happening.

I've taken a patch in a different traceroute program, enhanced it a bit plus
documented it and submitted it to the authors (last release of traceroute was
year or two ago though, so I'm not looking forward to response..).

The change is minimal and affects only operation in -t mode (see the patch).
