The standard tcpdump program is used for ETH monitoring. An arbitrary user rule in tcpdump
syntax can be written in the text box. The rule is then added after the rules generated from
the filters set for the ETH interface on this web page.
NOTE: Not all general rules are supported. When unsupported or wrong syntaxes are used,
the warning (ETH monitoring terminated. Invalid tcpdump parameters?) will be displayed.
■

Upon clicking the
File start
button, the file is cleared and the monitoring output is copied into it.
When the selected
File period
expires or the
File size
has been reached, whichever event occurs
first, the file is closed and left waiting to be

later. The
start
and
stop
of monitoring
to file is independent of the on-line monitoring, i.e. the monitoring output is recorded even when
the on-line monitoring is stopped.
■
Buttons
Buttons located at the bottom of the monitoring screen come in two groups:
left:
Start
,
Stop
,
Clear
buttons, which control the on-line monitoring, and
right:
File Start
,
File Stop
,
File Status
,
Download
buttons, which control the recording into the
file.
The two processes can be started/stopped by the respective buttons independently any time. Only
one of the
Start
/
Stop
(
File Start
/
File Stop
) button pair is accessible at a time, depending on the
status of the respective monitoring process (the other button is gray).
The
Clear
button clears the screen with on-line monitoring output, even when the monitoring is
running at the moment.
The
File Status
button refreshes the status of the file which is stored in RipEX and of the recording
process. It is recommended to use this button whenever you can not be sure whether your browser
is synchronized with the server in the RipEX.
The
Download
button invokes the Download File dialog.
Whenever the
Start
or
File Start
button is activated, the current settings of the monitoring from
your web page are applied. When you change any setting on the page, both Start and File Start
