4.3. Start Capturing

One of the following methods can be used to start capturing packets with Ethereal:

You can get an overview of the available local interfaces using the "

Capture Interfaces"

dialog box, see

Figure 4.1, “The "Capture Interfaces" dialog box”

. You can start a capture from

this dialog box, using (one of) the "Capture" button(s).

You can start capturing using the "

Capture Options" dialog box, see

Figure 4.2, “The

"Capture Options" dialog box”

.

If you have selected the right capture options before, you can immediately start a capture using
the "

Capture Start" menu / toolbar item. The capture process will start immediately.

If you already know the name of the capture interface, you can start Ethereal from the command
line and use the following:

ethereal -i eth0 -k

This will start Ethereal capturing on interface eth0, more details can be found at:

Section 9.2,
