Some tools for viewing and analyzing tcpdump trace files are available
from the Internet Traffic Archive:
- http://town.hall.org/Archives/pub/ITA/
+ http://www.acm.org/sigcomm/ITA/
+
+Another tool that tcpdump users might find useful is tcpslice:
+
+ ftp://ftp.ee.lbl.gov/tcpslice.tar.Z
+
+It is a program that can be used to extract portions of tcpdump binary
+trace files. See the above distribution for further details and
+documentation.
