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. -- Pete Cresswell |

GPs? 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.". -- Pete Cresswell |

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. -- Pete Cresswell |

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 Cresswell |

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. -- Char Jackson |

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. -- Char Jackson |

Per Char Jackson:
Pete, what kind of tuners are you using, and what video format do they record in? 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.... -) -- Pete Cresswell |

I should probably set it all up again one of these days, especially since SageTV is still being developed. -- Char Jackson |

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?) -- J. P. Gilliver.

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. 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. |

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. 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. |

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. -- Pete Cresswell |

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. |
