tcptrace sack example
This simple example is for a file
captured by the tcpdump program. If you run the program
tcptrace on the file, as such:
tcptrace sack.dump
you'll see the
brief output
of the program
If you run the program again, asking for "long" format output,
as in:
tcptrace -l sack.dump
you'll see more
detailed information
If you want round trip time information (slower),
you can use:
tcptrace -lr sack.dump
you'll see very
detailed information
Finally, here's some nice pictures of SACKs at work:
1,
2,
3, and
4.
