tcpdump
Creates a dump of the TCP traffic flowing between
clients and the virtual SSL server. You are prompted to
enter the following information:
•
tcpdump flags and tcpdump filter — for
more information about the flags and filter
expressions available for TCPDUMP using UNIX,
see http://www.tcpdump.org/tcpdump_man.html.
• output mode
Options for the output mode are:
•
interactive — captured information displays
on the screen
•
tftp|ftp|sftp — the dump will be saved as a
file to the file exchange server you specify, using a
destination file name you specify. You are prompted
to enter the required information. You can specify
the file exchange server using either the host name
or the IP address.
For TFTP, the number of files sent depends on the
amount of captured information. A sequence
number is appended to the file name given in the
CLI, starting at 1 and incremented automatically for
additional files.
For
ftp and sftp, you will also be prompted to
specify a user name and password valid on the file
exchange server.
You can read a saved TCP traffic dump file using the
TCPDUMP or Ethereal application on a remote
machine.
The default output mode is
interactive.

page 145).
To be able to use a host name, the DNS parameters
