Desafortunadamente, no leo a espa�oles.

I used Systran's on-line translation service:

	http://www.systransoft.com/

to transle your question to English - although it apparently thought
"tenia problemas con el tcdump" meant "tapeworm problems with tcdump" -
and to translate "Unfortunately, I don't read Spanish" into Spanish.

I won't use Systran to translate my reply back into Spanish, as it will
probably translate my reply into something that tells you to put noodles
into your computer, or something such as that.

The "Interface" field should have, on the right of that field, a
triangle pointing down; if you click on that triangle, it should show
you a list of the network interfaces on which Ethereal can capture
network traffic.  (In English, that's called a "combo box"; I don't know
what it's called in Spanish.)

If there is only one network interface in that list, Ethereal should
already have put that interface's name in the "Interface" field.

If there is more than one network interface in that list, you should
select the interface which is attached to the network on which you are
trying to capture traffic.

If there are no network interfaces in that list, Ethereal cannot capture
on any of the network interfaces on your machine; if that is the case,
you should install the WinDump program from

	http://netgroup-serv.polito.it/windump/

and try running the WinDump program with the "-D" command-line argument.
If, when you do that, WinDump does not print any network interfaces, the
WinPcap library and device driver can't capture on any of your network
interfaces; send mail to

	winpcap@xxxxxxxxxxxxxxxxxxxxxxx

asking for help - in the mail, tell them which version of Windows you
are using, and what type of network interfaces are on your computer.

You can leave the "File" field blank; Ethereal will put the captured
network traffic into a temporary file if you leave the "File" field
blank, and if you want to save the captured network traffic after you
have finished capturing it, you can use the "Save As" menu item in the
"File" menu.

The "Filter" field can be used to tell Ethereal to capture only some
network traffic; the string you would type in that field would be an
expression of the same sort that tcpdump uses - see the WinDump manual
page at

	http://netgroup-serv.polito.it/windump/docs/manual.htm

and look under "expression".
