How do I set up Wake-On-Lan (WOL)?

[George]

Am using WinXP and have Linksy router (with DSL) and fairly new Dell
PC...which has wake-on-lan (WOL) capability on motherboard

I'd just simply like to use the WOL feature and remotely turn my PCs on (or
off) so I can access them. That way, I don't leave them "on" all the time,
which protects them from lightning, makes sure no one can access them
through the router since the PC's are "off", saves a few ounces of cooling
and energy costs, and lastly passers by won't see an "on" PC they could
plink on. Even if these aren't big things, I'd still like to remotely turn
"on" and "off" the PC.

So far, I can't seem to find anyone anywhere who can say HOW to use the WOL
feature (in plain terms) through the router, and actually turn on/off my PCs
back in the office from a remote laptop PC while traveling.

Can anyone assist, do I "have" to buy PCAnywhere, isn't there a simple way
to send the PC a packet (that's what I understand it needs to see) that says
"wake up" and another one that says "sleep" or "off".

Thanks,
George

Thanks, Jack, for the link to great info

About leaving a port open (I think that's right, right?)... are these true
or false (I know this is hokey but didnt' know a better way to ask what are
really serous questions)?

-T/F. There's no way to secure a port that is left open, that is... there's
no such thing as a "secure open port"

-T/F. If the PC's asleep, a hacker wouldn't see anything (file, data, etc.)
because it's asleep...unless he knew to send the wake-up magic packet, which
itself has some codes in it. So, there's some security right there since
he's got several hurdles to get past...finding the open port, knowing to
send a magic packet, knowing what has to be in the packet, then getting to
the PC and it''s IP address. Right?

-T/F. In general, there will be no open ports on a router-out-of-the-box
installation. It's only when the user opens one that the security risk goes
up.

-T/F. In general, ports are open only when the router is CONNECTED to the
Internet, which for DSL is always-on, except after the (in many cases, 5-10
minute) timeout after which the router disconnects itself until someone
checks email or something.

-T/F. Open ports are generally hard to find, there isn't any software out
there that constantly knows on doors (ports) just to see which ones are open
to then tell someone that that it's open and they can easily enter my PC

Thanks

A: No way with simple Home Network.

A: Wrong. That what Hackers Do they have program that scans IPs for open
ports.

It comes to a point similar to crossing the Street. There is always a chance
for an Accident and an injury, however most of us do not stay at home
because of it.

So my personal feeling is.

While crossing the street, you look to both sides, you use traffic lights
when available etc.

Same with the Internet know what you do protect your system, and leave the
odds and the Paranoia to the Media.
