That's just hardware. The router should see the PPoE connection as soon
as your link is up. Once the little lights on the modem have stopped
flashing, you should be connected. If you turn the router off at night
too, you should probably power it up first, although, now that I think
about it, it really shouldn't matter.

I fully agree with almost all your points; and I partially agree with the

Understood. But, as you noted, that's a LOT more effort than just
unplugging the router momentarily (which is what I do today to accomplish
my goal). Actually, if I just found a router with an on/off switch, THAT
would be work just fine too! I didn't know that was a desired feature when
I originally purchased my Linksys router. In the future, a basic on/off
switch is on my list of router niceties.

I only partially agree with you here. For you, and for most of the people
who posted, changing the IP assigned to you provides no value. But, for me,
where my ISP reports to the whole world my assigned IP address in every
post, it does provide additive value for the amount of work involved
(currently that work is merely unplugging the router momentarily after a
night's rest).

I don't actually post on alt.personals, by the way. That was just an
example to explain the "why" I was asking how to force the router to dial
into my PPPoE connection on demand. I didn't want to get into a discussion
of why ... it's all the nice people who responded who insisted we discuss
the why before we discuss the how. So, I told them why by using analogies
(some automatically assumed I was a criminal, paranoid, or worse!) :) LOL.

I think we've discussed the "why" to death ... if someone doesn't
understand the why by now (yes, I know you understood), then they most
likely won't ever get to the how (which is a much simpler question, albeit
non emotional).

Yup. We proved it time and time again. Notice each day my nntp posting host
changes? It is 100% correlated with the IP address my ISP assigns me. It
doesn't matter which software I used (I tested Forte Free Agent, 40Tude
dialog, and Outlook Express). If anyone KNOWs the trick to tell the ISP to
not use my IP address as my NNTP posting host ... THAT would be a
conversation worthy of having!

Or, I can just tell my router to dial into PPPoE every morning :)

Again. These were just examples. Do folks really think someone who wishes
to hide their IP address is going to actually provide "real" targeting
information to answer a wholly unrelated, yet still very personal, set of
errant questions of why I want my router to dial into a PPPoE account on
demand?

The made-up examples were illustrative of the only point I had which was
that all my posts today under any name can be collected by the IP address
for me (but not for most of you).

> You are not going to get enough anonymity from changing

At the moment, the "cost" of changing my IP address is momentarily
rebooting the router (sometimes it takes a few cycles). You are precisely
agreeing with me in that I am trying to get that "effort" down to zero by
intelligent setup of the router (to make it dial into the PPPoE account on
demand).

I think I've set the router to do that so we are testing it now (it failed
the first test, but, my test may have been flawed as I had shut down the
modem).

It's more like the ISP is putting my name tag (i.e., my assigned DHCP IP
address) over my shower in a very public place where everyone else is
taking a shower ... but their (and your) ISP doesn't put their/your name
tag over their/your shower so folks are not concerned with my problem with
it because they don't have the same problem.

I think we've established that this is additive to security. Of course, we
all know that a security camera can record that you were there and that
someone can walk by and watch what you're doing (think tempest) ... but
what we were talking about specifically was the PACKET traffic.

I think we've reliably established the only thing that the PACKET traffic
reveals about you (other than the content which is likely more revealing
overall in a global sense) is that you CHANGED your MAC address.

Thousands of identity theft victims believed as you do. I understand your
point, and you understand mine, so we can just agree to disagree that
setting up a router to automatically dial into a PPPoE account on demand is
pointless (I believe it isn't; you believe it is).

Sigh. You do understand the situation well. So do I. It all boils down to
the shower-curtain analogy. THEY don't have THEIR assigned IP address on
their shower stall in the public shower; I do.

That makes my situation different than most of theirs. I know you
understand that. But they (seemingly) fail to understand that; yet, in
their willingness to help (which I do appreciate) they try to put me in
their shower slippers instead of the other way around.

It will. For the five seconds it takes to change the MAC address, the
security is additive and provides good ROI.

> If you give me reason to track you down, it won't even slow me down.

Please realize I never said it would. All you'd need to do is tempest
monitoring or security cameras or food receipts or interviewing the hotel
employees, etc. I KNOW that. That was NEVER the issue. Why people can't get
that in their minds (yes, I know you understand), is beyond me. All I was
asking on the MAC address question was about the tattletale bit.

Some people, sounding very knowledgeable, say there is "no such thing";
while others, sounding just as knowledgeable sare "there is such a thing".
From what I read (and posted the references), there is such a thing but I
asked the jury to help me here as we already determined changing the MAC
address prior to initating a public hotspot connection IS additive.

I disagree with this whole set of statements (including the first line).

You don't just want to be read ... you want the answers (what good is being
read without getting the answer????).

If you want the answer to the question, then you ask good questions and you
respond promptly, accurately, and courteously to all questions that try to
flesh out the problem ... and then you diligently try the viable suggested
solutions.

Can anyone say I am not?

In summary ... I asked many times how to force the router to dial into the
PPPoE account on demand ... and I am in the middle of tests from the one or
two answers which provided how to do that ... I hope these tests work ...
I'll know tomorrow morning after the router and modem have been down for a
few hours.

My IP adddress is current: NNTP-Posting-Host: 69.110.16.49

Tomorrow, if it's different ... then we will have succeeded and I will
thank you all for your kind help!

Well, it seems you have solved your problem. Whether you can automate
that solution is another question. I have a "similar" problem, that I
use a slightly different solution to, and which may guide you to a
better solution. Sometimes my modem gets stuck and needs to be
rebooted (and when that happens, you need to power it and the router
off). Therefore, I put the modem on a surge protect (power strip)
with a convenient button right below my screen. If things get stuck,
I trun it off, wait for 30 seconds and turn it back on. Viola.

Now, you can also get things (power controllers) like that, where your
computer can send commands to turn the thing off-and-on (often called
X10 devices). I don't know much about them, but I bet you could get
one of those to power your router and/or modem and thus have your
computer turn the router off and on once per night and then check the
ip address and do it again, until it got a new one. Now, your
shower-stall has a changing IP address.

I still don't think anyone is ever going to look at your IP address,
but I'm pretty much on the opposite end of paranoid, despite having
closely know people whose identities were stolen--and that's because
I'm pretty certain that their identities were not stolen by using the
same name over and over again, but by other forms of carelessness.

I lock my car when I go to work or the mall, but not when it is at
home in my garage, even though there is "only" an electric garage door
opener protecting it there. My wife locks her car even at home. That
helps her sleep better.

Hope this helps,
-Chris

It would be simpler to use a public news server that puts its IP address in
that line, wouldn't it? The tracking would still be there, but into a
public mass.

I think there were a lot of reasons why different people were down on the
idea. Mostly because it provides no protection at the time. It is more
like a doubleclick cookie. Over time, tracking the IP address could
provide a trail of crumbs. If that pile of crumbs belongs to
"anyone@isp.com" it isn't so helpful, but if some of the postings from
123.45.67.89 contain personally recognizable information, and none contain
dissuading information, an identity for all of them can be inferred.

In the case of the OP, it does seem to be a pacbell.net dsl IP. That's a
cookie that I might rather avoid, but then I have my .sig with my name...
Aside from Usenet postings, that IP address would be a useful part of
various web sites' collection activities.

You can't override that header. It's put there by your isp (or your news
service). You can subsrcibe to a private news service. Look at my
NNTP-posting-host; you won't get my real IP without a court order or
some serious social engineering. Pretending to be a lawyer won't work.
