User`s guide

The interface option must be set to the NIC currently installed and in operation. Note that in

the example there are four options available. This list is from Ethereal as it appears when

installed in Windows XP. For this operating system, the list contains the NIC by MAC address.

Other versions of Windows create a list by pseudo-names (for example, cw10, PPPMAC,

wldel48, and so on). Linux’s list, on the other hand, is by interface name (for example, wlan0,

eth0, eth1,and so on).

Next, you have the capability to adjust various aspects of how Ethereal captures

information. For example, you can set it up to filter the data and only capture HTTP information.

Or, you can capture the data and update Ethereal’s display in real time. You can also set up the

ring buffer to create numerous files in case you collect the maximum number of packets required

to fill up the first file (it allows you to capture infinite amounts of data). You can also adjust

name resolution settings, which might speed up processing, but which might reduce valuable

data if disabled.

NOTE

Using Ethereal will affect your normal network connection. If you place the NIC in

promiscuous mode, you could have various connection issues.
