Some folks have been using email since the late 70s, before there was
really such a thing as a full-screen text editor (may the spirits have
mercy upon you if you remember edlin, for instance), which explains
bottom-posting (it was the only viable way to do it).

Inline posting seems more common among people who started communicating
online in the 80s (it was common in Fidonet BBS messaging), and when emails
took several days to get from one place to another, the context probably
was valuable to help you remember where you were in a discussion.

Top-posting became more common when email became more accessible to the
general public, along with the rise of the Internet generally, probably
starting in the early 1990s.

This doesn't explain why I prefer bottom-posting, as I'm too young to
remember anything before the mid-90s, but (shrug)

For that matter, if you're comfortable with Perl, I've cleaned up my old

The government isn't trying to protect the small business owner - they're
trying to protect the perceived interest of the majority of common citizens.

A majority of citizens are using bigger carriers (cable companies and
telcos), and that majority likely will benefit from these rules. Yes, it
kinda stinks for smaller businesses, but them's the breaks sometimes.

Anyone that has access to the members list care to comment on what WISPA is
doing to ease compliance for small ISPs?

Why not just get a whole new USB wireless device (which will probably be
newer, have a better receiver, probably a better antenna, and maybe even an
external antenna lead if they're really desperate)?

If you can educate them into buying a product that actually exists, you
could even sell them that product and make a few dollars on the way.

I don't quite understand this. If it's one 25MHz transmit channel, and one
25MHz receive channel, how is that the equivalent of a 50MHz channel? To me,
it looks like the equivalent of 25MHz full-duplex channel - just one where
the rx and tx are actually on separate channels, but they're still only
25MHz wide each.

I agree with the intent of the NPRM, if not some of its language, but the

Some WISPA lists are publicly archived, so you can use Google as your backup

lists.wispa.org, and a rudimentary search tool at search.wispa.org/members,

Chances are, most folks here will suggest either Imagestream routers,
or something running Mikrotik's RouterOS. I've used both in my network
over the last few years, and they both have all the functionality I
need (basic routing and firewalling, BGP, and not much else), at
prices that beat the pants off even eBay'ed Cisco gear.

If you can go into more details on what you actually need your router
to do, we'll be able to provide better/more specific suggestions.

I honestly thought that even unconnected stations periodically transmitted

So YOU'RE the one connecting to my home network! :)

Even with a gibberish SSID, the radio will still be active. With Ubiquiti
gear, it's probably better to just explicitly disable the WLAN interface.

For the OP, though, I don't think Tranzeo gear gives you a way to do this.
Setting it to station mode, looking for a gibberish SSID, and turning the Tx
power down, is probably the next best thing to simply unplugging the power
cord. (Is this radio someplace where pulling the power would be
inconvenient?)

You'll probably have better luck finding a small local outfit to do this,
precisely because the big companies usually have large minimum orders.

If you do want to do it all online, try customink.com. Can't vouch for their

them with no problems. Their Web site they have a minimum embroidery order
of just 6 shirts, and you can mix-and-match.

I tried something like that a while back - we got so very many angry phone

didn't try to limit by video type, just "any single ongoing TCP

There is a lot of good knowledge in there, but it was hard to find - in part
because the page numbers are on the inside, by the spine, instead of on the
outer corner of the page where they're supposed to be. Lots of typographical
errors, a few spelling errors, lots of awkward-sounding first-person voice.

Maybe I've been spoiled by O'Reilly's high standards for technical books --
or maybe I'm nitpicky because I was a newspaper copy editor during college
-- but it really seems like Dennis' copy editor fell asleep. I still have it
on the shelf, and it's not bad, but it could be a lot better. I'd jump all
over a copy of "Learn RouterOS, Second Edition," though, with a better index
and a bit of polish.

Ubiqiti's "Level 2 ToughCable" might work for you. Each twisted pair is
shielded, with a divider in the cable, then the whole cable has a second
layer of shielding. Works well on normal tower runs, but I've never put it
anywhere close to a transmitter that powerful, so I can't vouch for it in

That's large enough, that it's almost certainly more cost-effective to do it
in-house.

If I were inclined to make up bogus rules-of-thumb, I'd probably say that if
you have fewer than 1000 mailboxes it's likely less expensive to outsource,
and over 5000 you should be doing it in-house. There's a lot of grey area
between those two number, though.

If you do it in-house, there are hardware costs, software costs (even with
open-source you should be donating to the projects that keep your business
running), electricity, cooling, paying someone to keep an eye on all of the
above and to fix it when it breaks... Many people overlook all these
overhead expenses. When you outsource, they give you one number. In-house,
you have to remember to add up all those little numbers, and not everyone
does.

You could work around that, if you're still willing to run servers on-site.
Point off-site people to Google's MX, run a small SMTP server for your own
customers. POP3, you could work around with something like Perdition. It's
kinda a hack, but it should work in the short-term while you migrate users'
settings.

The pricing might not be that bad, depending on the size of your user base.
If you're hosting your own email, you'll have to pay for some sort of email
filtering (spam and virus), pay for electricity to keep the mail server
running, pay for bandwidth for the 90% of your incoming email that ends up
being discarded by the spam filters anyway.

My network still hosts mail in-house, but it's getting closer and closer to
the point that we can cost-effectively move it out.

Few years back, IPpay told me they were working on something that was

they eventually abandoned the project. I'm in the same situation as you -
Emerald 4.5 works just fine for us, and authorize.net works just fine for

I just did something similar to this. The way I did it was:

* Get IP connectivity between the two boxes
* On one location, create a OVPN server, and for its PPP credentials, give
it a pair of private IPs (local IP 10.1.1.1, remote 10.1.1.2, for example)
* On that one, create an EoIP tunnel pointing to 10.1.1.2
* On the remote location, create an OVPN client, and an EoIP tunnel,
opposite of the above
* On both radios, create a bridge, and bridge the EoIP and an unused
physical interface

What should happen is the OVPN client connects, then brings up the EoIP
connection. Plug something into the bridged interfaces on either side. There
you go, you have a really long Ethernet cable.

Do you mean "queue?"

Anyway, the easiest thing to do is just to watch your traffic at the edge.
If you're using Mikrotik, the integrated Torch tool is pretty nice, and can
limit traffic by physical interface, or by IP. Valemount StarOS has a
similar tool, as do most wireless platforms these days.. Failing that, set
up a mirror port on a switch and fire up Wireshark.

If you're doing the traffic shaping at each tower, why would you need or
want to shape it at the edge?

If their contract says they get 20 GB of transfer in a billing cycle, and
they use more, you bill them. If they don't pay, you shut them off or sue

No, I'm referring to an instance where the queue definitely doesn't work.

(After eight years of working for a WISP, there finally is coverage at my
home. With the boss' okay, I gave myself more bandwidth than the normal
customer, using exactly the same rules we do on dozens of other routers. On
this router, a PowerPC-based RB1100, they don't work. Since the only "new"
component is the specific Routerboard in use, it seems the most likely
culprit.)

I recently picked up an RB1100, with RouterOS 4.16, and seem to be having
the same sort of problem. My weird fancy PCQ queues work great, but some of
my simple queues, that should take priority over them, don't seem to be
working. I'm using basically the same sorts of queuing that I'm using on
dozens of other boards, the only difference being that this one is PowerPC
and not MIPS (like all the 400s and 750s we use).

Anyone know the official way to file a Mikrotik bug report?

Titan Wireless doesn't design those. Mikrotik themselves makes the RB1000U
and its poor airflow setup (
http://www.routerboard.com/pricelist.php?showProduct=58), Titan just resells
it. While the RB1100U isn't on Mikrotik's site, the pictures are very
similar, so it's probably safe to assume that one also was designed by
Mikrotik.

Link Technologies' PowerRouter line is pretty nice, but might be a bit

What's the best source for updated documentation and explanation? This

Many, but certainly not all. There are three McD's near here, only one of

Redbox machines, and one gas station has a Blockbuster Express.)

Shame the selection is usually pretty paltry - if you want to watch

There's one video rental store in town, and I can't recall the last time I

Isn't this exactly why the FCC now requests counts by census tract? ZIP
codes are awfully big in some places, and just because an ISP can service
one person in a ZIP, doesn't guarantee they can service everyone.

Could you do something crazy like put their site in an iframe? Have the
"parent" page include their mandatory page, and a bit of JavaScript. That
JavaScript has their MAC embedded in a link, using the same sort of link as
the "click to accept TOS" link, which auto-refreshes after one second (thus
logging them in as though they'd clicked that link themselves). Then add
their page (and whatever other things it uses) to the walled-garden.

Yes, this fails if they disable JavaScript, but it's a reasonable price to
pay.

I suppose, in that case, you could keep a few wireless bridges around to
lend to guests, with crossover cables, with their MACs already
pre-authorized. (Might have to have it do NAT, so the AP only sees its MAC
and not the MAC of the Xbox or whatever. Depends on the device.)

Or get the system's MAC, but that adds a lot of extra complications (your
hotel clerks now need to know how to get that information from every device
ever made, and how to add the MAC to an ACL somewhere).

I'm doing something very similar to this. I just put the whole mandatory
page on the Mikrotik box itself, and made the "I agree to the TOS" link into
a "silently log this MAC into the hotspot for 24 hours" link.

 If you claim telephony isn't a natural monopoly, by the definition of that

http://support.vzw.com/information/network_extender.html

I've not used that one, but I've used a similar device from Sprint. For
calls, the bandwidth used is negligible (40-50kbps).

The Verizon one supports EVDO data (Sprint's Airave femtocell didn't, IIRC),
so if the phone is being used for cellular data that will increase the usage
somewhat. Since the device requires broadband anyway, if the phone has
wi-fi, just use it instead of EVDO; you'll probably get better performance.
I vaguely remember reading that all calls and data transactions from a
femtocell like this have to be tunneled through the carrier's network for
CALEA purposes, which would obviously add latency, but I don't have a cite
for this statement.

You might be able to work around some of that with DNS trickery. Or, you can

First, by "very large files" I'm thinking tens of terabytes. Second, there's
only a benefit to jumbo-frames if EVERY device between the two endpoints
supports it. Chances are, the end-user's desktop doesn't support it (or
doesn't have it enabled), or you've got an old switch at a tower, or someone
at a co-lo on the other coast forgot to enable it. If any piece of gear
between the two doesn't support jumbo frames, your giant packet will get
fragmented anyway, and you may end up with worse performance.

Obviously, you want to bench-test for your particular application, but
outside of some specialized environments (like Internet2) jumbo frames don't
really win you very much.

It probably won't hurt, but unless you're regularly moving very large files
point-to-point (and can enable jumbo frames on all the intermediate gear) it
also probably won't have any noticeable benefit.

Since you did the mapping, you seem like a good person to ask some of

Do you have any data showing how the adoption of broadband relates to,

If you're big enough to have a Microsoft volume license, ask your
sales rep about "Windows Fundamentals for Legacy PCs". It's basically
a stripped-down WinXP, specifically designed for older hardware. Then
you can just pick up any random used laptop from eBay.

In the long term, the "right" thing to do is to talk to your software
vendors and tell them to start supporting modern OSes.

(What software are you using that doesn't work well with Windows 7,

perfectly, and I'm even running the 64-bit version of Win7 for maximum
nuisance.)

I think a Windows server (configured with the routes you need), talking to a
Windows client, handles setting that up on its own.

For Linux, it should be easy enough to create a shell script that creates
the routes you need. Something like:

#!/bin/bash
route add 10.10.10.0/24 via $1
route add 10.20.30.0/24 via $1
... and so on

Then, once you're logged in, just run "myroutes.sh 10.50.13.41". Depending
on your PPTP client setup, you probably can even get this script to run
automatically as part of setting up the session. You'll probably also want a
similar script to run after you log out, with a bunch of 'route del'
commands.

Are you then setting a few specific routes (so that only your network is
routed through the PPTP connection)? You'd probably just need to, after
you're connected, add a few routes manually (i.e. something like 'route add
-net 10.20.30.0/24 gw your.ppp.peer.ip')

You'll probably want to automate that with a shell script or similar. I
think Fedora actually has a little GUI you can use, to automatically create
routes after setting up a PPTP session and drop them when you disconnect,
but I haven't had to do this in quite a while; I apologize for the lack of
specifics.

Sounds like your Linux setup isn't updating routes correctly.

What do you mean by not wanting to use the remote end as your gateway?
That's exactly what Windows does by default, and that's almost certainly
what you want, unless you're doing something very atypical.

That's a bit vague. Are you looking for something to sell to residential
customers so they can try to keep their kids from looking at naughty
pictures, or something for small businesses to keep their employees off
Facebook, or...

Without knowing who you're targeting, and their budget, it's kinda hard to

How much throughput do you need? Trango's Apex gear can, if you have big
enough antennas and pay for the licensing (both FCC and for Trango's
software), do something like 300Mbps.

You probably could, but you might not want to. You'd have three APs, all in
the same band, located less than an inch apart. There's often an unhealthy
amount of self-interference when you do things like that.

I've played with it in the past, but never could get much out of it. I think
there are two reasons for this.

First, in my network, the pain is actually last-mile (i.e. the extra load on
the last hop to the customer), and short of putting some kind of psychic
predictive cache in the customer's home, that can't be avoided.

The second problem, and the one that's probably more important, is that even
if the content were easily cache-able (it isn't), there wouldn't be much
point to it, because the odds that any two subscribers are watching the same
TV show, at the same time, with the same video settings, being streamed from
the same Akamai server, or within a few hours of one another, is pretty
slim.

Depending on what features you need, a Dell Powerconnect 2808 may serve
nicely. As a bonus, last time I looked they were around $100 each, which is
pretty darned cheap even by "low-end managed switch" standards.

I just received three notices of claimed copyright infringement for students

responsible). I've reduced these students' accounts to 128kbps for now.
Please contact these students and discipline them according to your TOS.

The student IDs in question are "downingel" (yes, I got two emails about
him) and "gordonta".

Hi.

Yeah, there's very little residential gear that would know what to do with
IPv6 address space (and, if you use radios that double as NATting routers
instead of just transparent bridges, relatively few of those that support
IPv6 either). Shame, that. Most IPv4 backhauls and such can pass IPv6
traffic just fine, but right now there are few places for the traffic to go
and few ways to get it there.

Spending your nights updating FreeBSD or Linux isn't any better. No matter
what you're running, it probably will need occasional updates. I almost
always try to schedule those updates for after-midnight, to minimize the
number of users affected by whatever-it-is being down. The only exception to
this is if something is fairly redundant. I'm willing to do work on one of
the incoming mail servers or DNS servers, for instance, since there are
several of those and one being down for a few minutes during the day won't
even be noticed.

I remember owning one of these, a long time ago. We had to pull it not
because of any issues with the software, but because of (indirect) hardware
problems. We used to not ground things as well as we do now. The system we
had had a PCI four-port Ethernet card installed, and over time lightning
rendered enough of the interfaces inoperable that we could no longer use the
system for that. (At the time, nobody in my office knew very much about
FreeBSD or NetBSD or whichever BSD it used, so replacing the card and simply
changing the interfaces' MACs in software wasn't feasible.)

ETInc, as such, we've just moved on.)

I don't know what issues specifically Trango was referring to, but while the
1.3.0 firmware has been on their Web site for a couple months, it was only
"officially" released about two weeks ago (and one of the files was quietly
updated in the interim). Trango Support told me not to use it, even though
it was on their FTP site for quite a while (labeled "pending release"), due
to some unspecified concerns they had.

I did install it on two Apex links (one 11Ghz, one 23GHz) as soon as they
said it was a final release, and I'm happy with it. While it introduced a
new cosmetic bug (the Web interface no longer shows the correct Tx/Rx
profiles in use, or the Ethernet interfaces' status if you use RPS), that's
a minor detail to me. The CLI has correct information for both of those, and
the fact that RPS actually WORKS properly (after two years of not working
reliably) brings me so much joy.

I have a pair of Trango Apex radios in that band, for a 22-mile link. Four
foot antennas. One side is about 130' AGL, the other is (I think) 250'.

There have been some thermal ducting issues over the last few months - at
least I assume it's thermal ducting. Occasionally, for a minute or two the
link will lose 15-20 points of SNR, and that often pushes the error rate
high enough that the radios temporarily lose modem lock. Almost always
happens just before or after dawn (give or take an hour). It usually fixes
itself within a minute or two, fortunately. Probably qualifies for
four-nines reliability, which is "good enough" for my purposes.

I forget where we bought the feedhorns from, but this can be done.

We actually just replaced two of them, doing exactly what you describe.
There was a catch, though. The feedhorn has two N connectors, a few inches
and ninety degrees apart. One of the two dishes had a smaller hole in the
center, and my climber had to take up snips and a rasp, and basically put a
small notch in the center of the dish, to get the new feedhorn to fit. The
other dish was older, or newer, or something, and already had a suitable
small notch in the center.

If you're going that route, it might be easier just to MPLS the BGP
customers all the way back to your NOC (or another central point a couple
steps removed from the towers), and do the BGP peering there. To the
customer, it still should look like one Ethernet segment so they don't have
to do multihop. Maybe still have a couple of these locations and multi-home
their BGP sessions. They'll still get all the benefits of your fancy
network, and suitable hardware will probably be a lot less expensive if you
only have to buy a couple big routers for your BGP sessions instead of
fitting it all into a large expensive switch.

Anyway, I can't find anything in the low end of the Cisco line that offers
that much RAM. No Catalyst gear, for instance. You'll likely need to look a
bit higher up in the "router" space, honestly. Probably not "Cisco CRS"
high, but this could be a fairly pricey project, which is why I'm trying to
think of alternatives.

Seems like an interesting combination of things there. If I may ask, why
don't you leave the ring stuff and switching to the switches, and routing
stuff like BGP to separate routers? It'll probably make things a lot easier
to set up, and you'll be free to get the best switches and the best routers
for your needs instead of trying to find something that's only so-so at
either task.

(Not intended as criticism, I'm actually kinda curious about this network
layout.)

First, keep in mind that Gmail doesn't support unencrypted POP3; you'll have
to use POP-over-SSL, which is on a different port and may not be supported
by some really old email clients. (The same applies to SMTP and IMAP, in
case such things are important to you.)

Second, you may want to find a way to do the forwarding by name instead of
IP, since Gmail has multiple addresses which could change (I just nslookup'd
pop.gmail.com and got a different IP from the one you listed above, for
instance).

If you want to keep residential customers in a competitive market, yeah,
you're gonna have to ease back on the profit-taking and build out your
network.

(I noted that you said you primarily serve business customers, so keep in
mind that "you" is the generic ISP, not you personally.)

Nobody has a free ride in this, though. Netflix/Hulu/whoever is paying TV
and movie companies for the right to redistribute content via the Internet,
and is paying Akamai/Limelight/whoever for bandwidth to do the actual
distribution. The end-user is paying Netflix for access to their collection
of movies, and is paying you for Internet connectivity in order to receive
bits from the Internet (in this case, bits from Netflix).


Sure... I'm perfectly fine with the bandwdith management method of control.

And I'd be fine with charging my customers one penny per bit (or buy a whole

very much at all. If your users are okay with this, go right ahead.

Your network, your rules. Legally, you can probably block whatever you want.
Doing so without informing your users (customers, for ISPs) is ethically
very iffy, but legally it's probably just fine. (Not a lawyer, et cetera)

It's probably a very bad idea, but that's another discussion. :)

If you mean that they're abusing your service, you'll have to clarify what
that means - the customer pays for bits to be delivered, and you're
delivering them. If you sell an "unlimited" service, them's the breaks. If
you bill by usage, just send them their next bill showing all the overages
they incurred, and that probably will be an effective deterrent all by
itself. :)

It would be just about impossible to do. Netflix uses Akamai, and Hulu uses
a mixture of Akamai and Limelight for "content delivery" services. These are
the same content-delivery services used by just about everyone that has lots
of content to distribute to lots of people (I'm pretty sure Microsoft uses
Akamai for Windows Update, for instance) - Akamai claims they're responsible
for 15 to 20 percent of all Web traffic on any given day, so blocking Akamai
wholesale would probably be the worst idea.

Wouldn't you have to get them to run BGP over this connection, so you can
keep things online? I suppose this would work if you were really desperate,
and willing to basically NAT your whole network, but you wouldn't want to do
that for more than a couple hours while the real links are repaired.

You may want to be careful with this. I've been waiting for 1.3.0 to fix a
pretty big showstopper bug (where RPS will disable the radio's data ports
but not re-enable them later), and while there's something on their FTP
dropbox, a Trango tech just told me that 1.3.0 hasn't yet officially been

If the workload is one that can be virtualized, buy one or two big servers

If not, I've been happy with eRacks (eracks.com), or of course Dell.

If you can avoid it, don't put two radios on the same band, in the same
enclosure. A 2.4 and 5.3 are okay, but if you have two 2.4 radios (for
example) you may have weird cross-talk and interference issues.

If you're not sure, just put up that second board; it's only a couple
hundred bucks, and could save you a lot of headaches.

The whole point of SFPs is that (in theory, anyway) they're pretty much
interchangeable, so long as you have the same optics at both ends and
compatible fiber between. For mine, we've got the official Trango ones in a
couple radios, a couple horribly-overpriced Dell ones, and a bunch of $50
ones from Newegg, and they all inter-operate perfectly.

If you're using multi-mode fiber (and for a tower, you probably are),
something like this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16833516014
will work just fine.

The broadband stimulus package had "increasing access to broadband" as a
primary goal, and "creating jobs" was at best a second-order effect. If the
primary goal were to create jobs or reduce unemployment, yes, there are many
more cost-effective ways to do so, but that wasn't the point of that little
part of the 2009 stimulus bill.

If you're using the Canopy to NAT, its default IP is 169.254.1.1. That's the
same block of IPs used by Windows for DHCP link-local addresses (
169.254.0.0/16). Windows 7 refuses to route traffic out through a link-local
address.

Solution: change your Canopy's internal IP from the default 169.254.1.1 to
something like 10.0.0.1 or 192.168.1.1 (basically, one of the proper RFC1918
blocks).

You can still buy OEM media and licenses from a number of resellers, like
Newegg. XP Pro should be around $150 per license.

Depending on what you're doing, it may be easier/cheaper to get a small
volume license of Windows 7 Professional, then use "Windows XP Mode" (a
customized copy of Microsoft Virtual PC with a pre-installed XP
environment).

I'd suggest you have a nice long talk about this with your lawyer before
doing anything like this. Sounds like a good way to open yourself up to
liability if your blocking isn't 100% effective (it won't be) and little
