Installing Tcpview

1. Create a directory for the tcpview support files.  I use 
/usr/local/lib/tcpview.  Create /usr/local/lib/tcpview/filters for the filters.
Copy BGP, generic, and telnet from bin to the filters directory. Copy
manuf and hosts to /usr/local/lib/tcpview.  Edit the last two files as 
needed.

2. Edit a copy of the tcpview resource file, which is DOC/Tcpview.  Change
the entries for Tcpview.filters, Tcpview.manuf, and Tcpview.hostnames to be the
same as step 1.

3. Put "Tcpview" in the system application resource
directory (usually /usr/lib/X11/app-defaults/ ) or set the environmental 
variable XAPPLRESDIR to your personal resource directory.

4. To decode SNMP packets, you need a copy of the SNMP MIB in MOSY format.
the file UTIL/mib.txt contains the basic MIB.  To add any site-specific mibs,
run them trhough MOSY and append them to the end of the standard MIB.  For
a copy of MOSY, download the UW-CMU SNMP package on ftp.cac.washington.edu.
Tcpdump and tcpview will search for the mib file in the following locations,
using the first one found: the environmental variable "MIBFILE", ./mib.txt,
and /usr/local/lib/tcpview/mib/mib.txt.

5. If you are running on an Ultrix system, you will have to run pfconfig
before you can capture any data.  On a Sun system, you should make
sure to install tcpdump and tcpview setuid to root.

Good luck.  If you have any major problems or suggestions, contact
