Default Download Speed Miserable, then A-OK following PC reboot?

Per VanguardLH:
How about the IP address shown by ipleak.net when they use WebRTC?


It shows "10.34.106", which is nothing familiar to me.

OTOH, the "Block:" property is 10.0.0/8 and 10.0.0 is my LAN's base address
template. OTOOH, "8" is not the addr of my PC (although it does happen to
be the addr of one of my NAS boxes).

This is all way above my pay grade... Does it still sound like I'm good
privacy-wise?

I can post screen shots of ipleak's output if anybody wants.

General Principles.

I don't know enough to understand all the posts here, but being able to
download torrented files is not exactly a religious issue with me - so "When
in doubt, pull it out.".

Per VanguardLH:
that might be another cause of Pete's mysterious upstream traffic


I found the cause of the mysterious upstream traffic: a Tivo-on-steroids app
called "SageTV". It runs on the affected PC and talks with little black
boxes (Unix PC's/"Media Extenders") under each television set.

Kill the SageTV service and the traffic stops. Restart said service and the
traffic resumes.

AFIK, there is no traffic outside of my LAN - so I was just *assuming* that
BitMeter's numbers applied to only WAN traffic.

Per croy:
Probably old news, but....

http://sagetv.com/:

"We’re thrilled to announce that SageTV has been acquired by Google."


The Bad News: A lot of SageTV users were not quite as thrilled.

The Good News: Google relented and released SageTV into the public domain
where it is being maintained/improved by dedicated enthusiasts.

I ran the paid version until Google bought them out some years ago.

Am now running the latest-and-greatest public domain version and it's still
the greatest thing since cheesecake: twenty bucks a year a TV program
schedule service, and that's it...otherwise a total freebie that *works*.

Pete, what kind of tuners are you using, and what video format do they
record in?

I still have a pair of HDHomerun tuners around here, but I haven't used
them in a while. They record in MPEG2, so about 6GB/hr. That adds up
pretty quickly.

IPv4 addresses have *4* octets, not just 3, so the address above is
incomplete.

OTOH, the "Block:" property is 10.0.0/8


That's almost certainly 10.0.0.0/8 -- note the addition of the 4th
octet.

and 10.0.0 is my LAN's base address template.


That should be 10.0.0.0.

OTOOH, "8" is not the addr of my PC (although it does happen to
be the addr of one of my NAS boxes).


The "8" in the example above is your network mask. Note that it's
delimited by the "/" rather than a ".". It tells you that almost
anything with a 10.x.x.x is valid for your LAN, with the obvious
exceptions of 10.0.0.0 (refers to 'this network') and 10.0.0.255
(broadcast address for your subnet), which are reserved in your case.
One additional IP address in that huge range will be used by your
gateway, so everything else is available for you to use.

That address range isn't Internet-routable (RFC1918). Therefore, it's
being NAT'd somewhere, either by you or by your ISP.

This is all way above my pay grade... Does it still sound like I'm good
privacy-wise?


We see that you're using RFC1918 addresses, so IMHO you're not a good
target for further investigation. You'd be a more exciting target if
your LAN hosts used routable IPs. Bottom line, IMHO, I don't think you
have anything to worry about via WebRTC.

HD HomeRun: one old ("Dual ATSC Tuner"/Model HDHR-US) and one newer ("HD
HomeRun EXTEND.FREE broadcast HDTV (2-Tuner)").

They put out .MPG, which SageTV takes as-is and records.

The newer one allows direct connections to it from Android devices.

Sounded really cool on paper, but I almost never use it since the Sage public
domain developers came out with a version of SageTV that runs under Android -
which, come to think of it, I also almost never use.... -)

Very cool, thanks. I should probably set it all up again one of these
days, especially since SageTV is still being developed.

No, BitMeter2 is a fairly simple application - it just monitors the
total traffic leaving and entering the computer it is running on,
regardless of where it's going to/coming from. I find it (especially its
audio option) a useful indication of when something suddenly starts to
use the network unexpectedly (or when a download suddenly stops or slows
down) - but it would be less so if I had much "local" traffic. (_Maybe_
something in one of the NirSoft or SysInternals suites can select only
certain traffic?)

I'll assume you accidentally omitted a period character (".") in that IP
address, probably in the last 3 digits; else, it is not valid.

That is the intranet IP address of your computer assigned by your
router's or cable modem's DHCP server or a static IP address assigned to
the host (in which case, someone had to go into the DNS config to change
to static since dynamic is the default).

That they reported an IP address discovered using WebRTC means there is
a WebRTC leak exposing the IP addresses inside your intranetwork (i.e.,
past any router's firewall or any software firewall you use on your
intranet hosts).

Whatever web browser you used to visit ipleak.net supports WebRTC and,
as a client, is divulging your host's intranet IP address. Whether you
care or not depends on whether or not you want any site you visit from
mapping out your intranet.

3rd party firewalls and some VPNs can block WebRTC traffic. I think
they block traffic on the RDP (5004) and STUN/TURN (3478) ports but that
would seem to affect intranet and Internet traffic. In a firewall in
the router or a gateway, they could block only the traffic that crosses
the router or gateway and not for intranet traffic that should merely go
through the router's/gateway's switching function (to route traffic
between intranet hosts).

https://tools.ietf.org/id/draft-jenn...rewall-01.html
"In general WebRTC media can be sent on a wide range of UDP ports but
the two ports that are commonly used are the the RTP port (5004) and
TURN port (3478). Some firewalls MAY choose to only allow flows where
the destination port on the outside of the firewall is one of these."

However, blocking the RTP port seems it would have wider ranging affect
than just blocking WebRTC.

https://en.wikipedia.org/wiki/Real-t...sport_Protocol

Any port could be used. WebSockets would use port 80 (which HTTP uses).
The IETF article mentions, "STUN messages all have a magic cookie value
of 0x2112A442 in the 4th to 8th byte." Since firewalls inspect the
packets, maybe that's how they snag the WebRTC traffic. The following
article mentions the protocols involved with WebRTC:

https://webrtchacks.com/an-intro-to-...ewall-problem/

The firewall in my router is basic: it's just a consumer-grade router
with a stateful firewall to block unsolicited inbound connection
requests (with a few options for user configuration). I don't bother
operating a gateway host or a firewall appliance before the router or
between the router and cable modem to run an enterprise-grade firewall.
I don't bother with 3rd party firewalls on my home PCs. I just disable
WebRTC in my web browsers since that's the only intrusion vector on my
computers than can use WebRTC.

Never much got into that stuff. My guess is the SageTV (e.g., HD
HomeRun) client is retrieving programming information or it's
communication between it and the server box (little box at the TV).
Long ago, it used to require the PC have a TV tuner card but that's
changed to having clients on the PCs communicate over the network to a
server host (little black box). For a while, I got interested in
SlingTV and using a wifi Roku HDMI dongle (so didn't need to run Cat5
cables) on all my TVs (all mine have 3 HDMI inputs) for streamed media
instead of paying Comcast for their TV programming. Since no one else
in the household wanted to abandon Comcast TV despite a big savings
going with Sling TV blue+orange channel lineups, and I wasn't going to
pay for just myself, that plan got scuttled. I also wanted to get rid
of Comcast Voice (drop their cable TV and voice services to just have
their Internet service, or Internet + basic TV since together the
discounted Internet might pay for basic TV) and go with Obitalk with
Google Voice for free VOIP (other than the initial $50 to get Obitalk).
Technology is not a forte in the rest of my family.

The server box might be a PVR. You sure you haven't programmed some
shows to watch at times other than when scheduled? If you're watching
that streamed media then there's network traffic to get that content.
Are you the only one in your household or are there others watching the
TV and getting the streamed media? I suspect that just because you and
no one else there has a TV turned on doesn't stop the little box from
continuing to retrieve streamed media for the last channel to which it
was tuned. Whatever you use for the media source (OTA, cable,
streaming) remains active regardless of the state of your TVs.

I didn't want a solution that ran through my PCs, so no installing a
client program on PCs (that would have to remain powered) to communicate
with a server box (perhaps the network traffic you see) at the TV. I'd
use an HDMI port on the TV to use Roku's own controls to decide what to
watch. That is, I'd use a solution that was local to the TV. Of
course, if you want to watch the shows on your computers then you
probably need their client installed on those computers. I spend way
too much time at my computers, so having TV somewhere else gets me away
from my computers although obviously I'm still sitting on my butt
("sitting is the new cancer"), more of a problem during winter months.

SageTV is, IMHO, the best thing since cheesecake.

Certainly TIVO is a lot slicker UI-wise - really an appliance - but they want
an arm and a log for the TV Guide service and last time I tried one there was
no convenient way to get, say, 6TB of storage connected.

It's probably a matter of taste, but with just OTA TV and NetFlix, I've got
more interesting, entertaining, relevant program material on hand than I can
possibly watch.

Maybe if I became bedridden or something I'd want more - but as it is I'm
chronically 5-6 weeks behind on my news magazine reading and only watch 10%
max of the recorded TV.

Reminded me of a guy at an old workplace that collected tons of
magazines, including those that we cleared out of several departments at
work. Some were very focused on a particular technology or science. I
asked why he had such a huge stockpile which was something like a dozen
stacks that each reached higher than the height of his cubicle. He said
he was going to read them. Geez, he couldn't get those read in 20 years
if retired at that time (he wasn't that far from retirement age).

One day I and some others heard a crash and started looking around.
Yep, we found a river of magazines flowing out his cubicle and found
this guy buried under all those magazines that had toppled over. Most
had shiny covers and putting them all in the same direction meant the
stapled side was thicker and tilted the piles. He was okay but we got a
good laugh as we pushed the magazines aside and pulled him up. Yep, all
those precious magazines had collapsed on him. Guess they demanded to
be read and took action to get attention. "We're right here!"

I get ticked when I spend more than a week after Scientific American
arrives to get through it cover to cover. Even if I don't understand
the technology or science being discussed in an article, I keep going
through it until I learn something. Sometimes I spend an entire flight
rereading just one article while frustrated that I don't have the
Internet to look up stuff to research the article.
