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,
“Start Ethereal from the command line”.
