You can add source and destination ports to the summary printout for
Ethereal/Tethereal by
changing the value for column.format in the preferences file
either manually or by
using the Edit/Preferences/User Interface/Columns dialogue from
Ethereal.
If you do it from Ethereal then you can e.g. add a column "Destination
port (unresolved)" which will correspond
to %uD in the preference file.
Please note that Ethereal needs to be restarted when you have changed the
settings (and pressed "Save") in order to
use the new column formats.
The same preferences file will be used by Ethereal and Tethereal.
Below is an extract from my preferences file. The location of the file may
vary depending on what OS you are using, e.g.
C:/Documents and Settings/Martin/Application
Data/Ethereal/preferences
# Packet list column format.
# Each pair of strings consists of a column title and its format.
column.format: "No.", "%m", "Time", "%t", "Source", "%s", "Destination",
"%d", "S_port", "%uS", "D_port", "%uD", "Len", "%L",
"Protocol", "%p", "Info", "%i"
