The packet display shows details of each captured and filtered packet. Up
to six columns of infornation can be displayed, as selected from the
common configuration page.
- Time
This is the time at which the packet was logged from the network. The
time is show as hours:minutes:seconds from midnight, plus, in principle,
microseconds. The accuracy of the latter depends on the system clock.
- Protocol
This shows the protocol (for instance, tcp or udp) plus
possible some extra information (for instance, arp who-has and
arp is-at).
- Source
This is the packet's source. Unless disabled from the global setup page,
IP addresses are converted to names, and ports to services. Note that
name lookup is done asynchronously so as not to hold up execution of
the monitor. Hence, the first few times an address appears it will not
be decoded.
- Destination
This is the packet's destination. The same comments apply.
- Info
This column contains miscellaneous other information, for instance IP
fragment size and offset values.
- Size
The size column contains two values, the total packet size and the data size.
See the comments here about the
interpretation of packet and data size.
