Re: [PLUG] WiFi router recommendation
The best "wifi" is ethernet cable. I've had good recent experience with the Linksys E8450. It's a dual band 802.11ax (i.e. wifi 6) router for about $100. No 5GHz penetrates walls very well. No coverage guarantees.

The first part is going to be a description of how I relay network connections from the Internet to my low-volume home-based email server to evade potential ISP blockages. Earlier this week, you might have heard about a large Pacific Power outage in Northeast Portland. It only lasted for 30 or 40 minutes, but it affected a wide area and reportedly on the order of 30k customers. I was one of those affected. I was at home at the time. When all the UPSes started screaming at me, and the power didn't come back on immediately, I thought I'd better be pro-active and start shutting down machines. And it's good I did because the batteries I have wouldn't have sustained the load for that long. I wandered around the neighborhood, chatting with neighbors, exchanging information, and began contemplating building a soapbox racer or possibly pushing wheels with sticks in the dark time with no internet connections. It turns out, reports local journalists, a beaver up near the Columbia Slough had chewed through a tree that fell into some transmission lines and (i'm guessing now) caused a brief fault and opened up a circuit breaker. There must not have been any significant damage to the line because power was restored pretty much as soon as they'd identified the cause. Lights come back on, and with some relief I commenced to go around and turn back on the machines I'd turned off. Some of the machines had been up for a long time, sustaining long running sessions, so the downage was a chance to catch up on the deferred maintenance. For example, I'd purchased a Core i7 975 on ebay to replace a first-gen i7 920, to max out the CPU in one of my desktop boxes. This was a chance to replace the CPU, which I did and got that box powered back up. I also power my mailserver back on, which had been running without a reboot for nearly a year. It gets regular updates, but I hadn't rebooted into a new kernel. You might recall, I gave a PLUG talk in March describing the cloud-based tunnel I used to connect the internet to the mailserver in my house, bypassing any obstructions my ISP might employ. It has been working great. Life seemingly returned to normal. Then, Friday morning, I caught wind in a meeting that some mail (turns out, it was just mail being forwarded from gmail to my home server) was bouncing and the senders were seeing this odd domain they hadn't emailed. Uh-oh. But I had plans today and was away from home most of the day. This evening, I remembered about the mailserver and decided I'd better figure out what was going wrong. I had also recently updated my letsencrypt certificate, and that sometimes causes trouble if the mailserver doesn't use the new certificate, and I need to restart or reload the service. Oh, and the machine runs Arch. And yes, I don't mind that it sometimes gives me paper cuts. We're coming to that. So I look at my cloud hosted relay. If you recall the talk, the relay is just relaying packets, there's no server there other than the vpn I use to do the tunneling. And some tricky port forwarding, masquerading, ip rules, etc. At first, I'm just looking at the postfix logs on my mailserver, and I'm not seeing anything inbound. I look in iptables on the mail server to see if I'm dropping anything overzealously. Not that I can tell. I run tcpdump on the cloud-based relay, and I see TCP connections coming in but no answers. Weird. And then I run tcpdump on my mail server and I see TCP connection attempts there as well, but nothing going back over the tunnel interface, as they should. And then I think: "Hey, wait a minute, didn't someone just talk about this? And, hey, wait a minute, wasn't that person ME??? Where the hell are my slides?" and I go and find them, and flip through until I find the relevant bits. I had annoyingly obfuscated some of the addresses for the audience, so I had to translate the examples in my slides back to my actual context. And I start checking things like, are the fwmark rules intact (they were) and how about that ip rule? What? No ip rule? So I type in my translation, guessing a little at the table name. And ip tells me, "no such table". What? I remind myself that the table names are listed in a file called /etc/iproute2/rt_tables. I look in my /etc/iproute2 directory and I find rt_tables.pacsave, but no rt_tables. The pacsave

If you have a continuity tester for the ethernet cabling, I'd check to make sure all of the wires connect, because the 100 Mbps limitation sounds like you don't have continuity on all four pairs.

Re: [PLUG] Comcast to Ziply fiber migration, plus Ooma phone
Clackamas County also got money from the 2009 stimulus bill to build a publicly-owned middle mile network that runs from Government Camp to the west end of the county near Lake Oswego and all the way to downtown Portland. This has made extending local networks much more affordable. https://www.clackamas.us/cbx One hilarious side note. Clackamas County publishes a map of where that fiber goes. If you ask the City of Portland to show you a map of their publicly-owned fiber network, which they use for internal corporate purposes and currently do not allow to be used to benefit their constituents, you will be told "oh no, we couldn't show you those maps, that's secret because it is Critical Infrastructure!" -- Russell Senior russ...@personaltelco.net On Sat, Apr 13, 2024 at 9:43 AM Aaron Burt wrote: > Fiber from the local telecom co-op isn't much more here in Eagle Creek, > just west of Sandy. > > It feels like a dam has opened up and flooded rural America with > Universal Service Fee money, in addition to the Infrastructure Act. > Reliance has been begging people to get fiber; they had to bore and run > probably 500-1000m of fiber just to get me hooked up, and I'm sure they > were well reimbursed for it.

I *think* universal service funds typically go to subsidize individual subscribers. The IIJA money is not yet flowing. Meanwhile, lobbyists in the state prevented ARPA funds, that were not previously restricted (IIJA/BEAD money was already restricted by the Feds), from going anywhere that would threaten their monopolies. And our bipartisan Industry Stooge legislature went along with the monopoly protection, because suitcases-full-of-cash and/or threats. If you are a voter in the 5th congressional district, let it be known that one of the candidates, as chair of the barely-relevant committee that considered the bill, was carrying water last session for Industry (i.e. the cable and telephone lobby), and her name was Janelle Bynum. If I was a registered voter in that district, and (speaking as a private individual and not as a representative of any non-profit organization that isn't allowed to endorse candidates) I would *not* be voting for her. For what it's worth, 3 out of 4 people without internet in Oregon live in areas that are considered "Served", but 100% of the federal funds you hear about are going to the remaining 1/4 of unconnected people who live in rural areas. And that is specifically and not accidentally to entrench the monopoly power of the existing providers. It is one thing if it is a co-op, that is organized to directly benefit the subscribers, but otherwise, those billions of dollars you have heard about are going to be building *new* unregulated monopolies, that private capital wasn't willing to invest in themselves, and which will *never* get a competing private-capital provider. I think that is an, admittedly normal, but egregious use of the public treasury. The word "affordable" is used a lot, but never defined and widely ignored. The entire 5-year Oregon strategy for affordability was a federal program that is ending this month, called the ACP. The state entity designated to manage the funds is a business development organization with no discernible utility regulation experience or inclination. -- Russell Senior

Cat5 can handle gigabit just fine over house-scale runs, in my experience. You might have a piece that only has two pairs connected, which would knock you down to 100Mbps.

Note that modern phone operating systems randomize the MAC address they use on each wifi network for the sake of privacy. You'll have to figure out what it is using either by looking in the phone or by looking at the DHCP lease your router provided. Then, let it run for as long as it takes to send your whatsapp message, but minimize other traffic on the phone, because the tcpdump will need to copy/store everything to and from the device. Then copy the /tmp/capture.pcap to a real computer and run wireshark on it, e.g.: wireshark capture.pcap And then stare at wireshare until it makes sense. The payloads of the messages will be encrypted, but the envelopes/headers and their timing should provide information.

Re: [PLUG] Quantum fiber WhatsApp latency issue
If you manage your own gateway, using OpenWrt for example, you could put your own diagnostic tools (like tcpdump) on that gateway and, for example, capture the transactions from your phone to whatsapp servers. If you don't manage your own gateway, then you might be stuck asking CenturyLink/Quantum what's going on.

My idea is to clue the AI program into the actual OS, then ask it to finish documenting 100% of all the executables, or report to me all executables which have no available documentation at all, period. This means the AI program would scour the internet for any and all documentation for each command, and there are 10,000's of executables to examine.

I would question the results simply due to the quality of current LLM implementations. From recent anecdotal experience, I recently bought an expensive Logitech keyboard and it was behaving strangely so I tried to look up how to perform a "factory reset" for this model. The search results I found via DDG were interesting, there were multiple duplicate hits for what appeared to be a tech blog with generic instruction pages for my device. However there were multiple iterations of this page, for this keyboard model, each of which had instructions referencing physical features that do not exist on this actual keyboard. These appeared to be AI generated help pages that were clogging up actual search results. They were very well written, If I hadn't had the actual device in front of my I might have actually believed that there was a pinhole reset button next to the USB port. If you do this, you may need to find a way to define a "web of trust" that allows the AI to differentiate between human written articles, and AI written summaries. As it is right now, you might find yourself telling an AI to summarize help pages that are AI written summaries of AI written summaries of ( AI written summaries of ( AI written summaries of ( AI written summaries of (actual manuals) ) ) ) Recursion FTW! :) It seems inevitable that the AI serpent will stupidly eat its tail and devolve into even more of a stochastic septic tank than it is now.

Re: [PLUG] Cable tester
For years, we got away with a cheapo $20 continuity tester for checking Ethernet cables. The problem with them was that, yeah, sure, they would tell you if you had shorts or opens, but they did not tell you where. Cable itself tends to be pretty reliably connected end to end, but when you have crimped both ends and you find a short or open with a continuity tester, you have almost no idea which end you screwed up. You look very closely at the crimped ends, decide which one looks sketchier, cut it off and try again more carefully, then rinse and repeat. A few years ago, after suffering this problem for over a decade, we finally invested in a fluke microscanner2. It does time domain reflectometry, and can tell you, pair-by-pair, whether it has continuity and crucially, if it does not, how far down the wire the fault occurs. Suddenly, we know which end has the fault! If we stabbed the cable to death with hoop staples and there is a mid span fault, we know that. It cost us $500. It wasn't their fanciest model, but it has been such an improvement in reliability and visibility. -- Russell Senior russ...@personaltelco.net On Mon, Jan 29, 2024, 09:21 mo wrote: > Hi.

Re: [PLUG] How to script USB device detection
Two things I will mention: lsusb and udev rules. I have a set of udev rules that match ttyusb devices by path (they don't implement serial numbers, which would be better) and give them a consistently named symlink. I use /dev/ttyRn, where n is a whole number. That means no matter what order they are enumerated in, I can find the device. I don't know if that helps with your problem or not, but I have found them to be useful in adjacent problems. -- Russell On Fri, Jan 19, 2024, 15:17 Vince Winter wrote: > Hello, > > I am trying to write a bash script to detect if USB device is plugged into > a device and post a message with a device name that is plugged to stdout. > > Complications are USB webcams, USB controllers, and this is going to be > used on large number of systems, so I can't customize to each system. >

You seem to be using the UUID for the disk. The filesystem or whatever it is you are trying to mount, is probably in a partitition. Use blkid to get the UUID of the appropriate partition.

Re: [PLUG] 'Linux devices are under attack by a never-before-seen worm' - ArsTechnica
It is a pet peeve of mine the kind of vulnerability journalism that seems to predominate today, which is all about the DANGER and not about modality or mitigation. You have to read far into the article (if it is there at all) to get any idea of what the vulnerability actually is and whether you are actually vulnerable, how to tell, and what you should do about it. Another good example is journalism around ransomware. To me, no story about ransomware should omit the kind-of-obvious mitigation of having up-to-date backups, and yet I NEVER see that mentioned. Just yesterday, I heard a story about cybersecurity that cited the huge number of "attacks" happening daily on the Internet. Probably (WAG) 95% by volume are brute force password guessing against ssh services. I see them a lot in my own logs of public facing machines, but at the rate passwords are being tried, my math suggests it will take many centuries to guess a decent password. Answer: have a decent password. -- Russell Senior russ...@personaltelco.net On Thu, Jan 11, 2024 at 12:29 PM Russell Senior wrote: > TL;DR, this is using password guessing.

THANKS TO ALL for EXCELLENT and COGENT responses to my question about Ziply static IP. $10 (or even $50) extra per month for a business class connection with a static IP is well worth it - much time and confusion saved when there is no time to debug my ONLY connection (needed to look things up). I know I can simulate static behavior with DHCP and dynamic DNS and proper configuration, but I prefer simple and robust to clever. I'm old enough that "clever" is in short supply. Regards "business rates and business department" ... I learned similar good info from a Ziply install tech (crusty opinionated overall-ed bearded ex-hippie, my favorite variety of expert) who was servicing a neighbor, a few months ago. He said the best part of Ziply business class is a US call center rather than Asian, staffed with people who know the subject rather than parrot menus. We talked for a while, but I forgot to ask him about static IP. Fwiw: I'm not a Comcast customer, but I've heard that Comcast uses off shore customer support for their residential customers. With Ziply Residential I seem to reach call centers in the southeast US, judging from their accents alone. I've never spoken to a customer or technical support agent when dealing with issues with my mom's service that sounded off-shore. -- Russell Senior russ...@pdxlinux.org
Re: [PLUG] fdisk not recognizing external SATA HDD
The last message seems to say that the USB device disconnected a couple minutes after it was plugged in. The sd in sdg stands for scsi disk. Prior to nvme, in Linux, storage tends to be treated as scsi disks because regardless of connection technology (USB, SATA, SAS, etc) the underlying commands sent to devices were scsi commands.

Look in dmesg output after plugging it in: dmesg -T (provides decoded timestamps) You can also run "smartctl -i /dev/sda" (etc) to get the model and serial numbers to make sure you are talking to the right thing.

Frontier acquired local wireline Verizon assets in 2010-ish. Verizon (then known as Bell Atlantic) bought GTE in 2000. As far as I recall, having grown up in GTE territory, they'd been the incumbent telephone company in the 'burbs since at least 1970. According to Ziply's wikipedia page: "General Telephone Company of the Northwest, Inc. was founded in 1964 following the acquisition of the West Coast Telephone Company and later became GTE Northwest, Incorporated. GTE Northwest originally served Idaho, Montana, Oregon, Washington."

Re: [PLUG] email issues
Getting on the wild-assed guess train, if you are using a firefox browser, you might consider (if you aren't already) using the quite nice Multi-Account Containers extension, and connect to each service in a different browser container. The only reason I suggest this is because *maybe* there is some alien cookie that is setting off a trigger, although as I think about this more this seems quite unlikely to be the problem and I only leave this in because I think this extension is really great and I want to make sure everyone knows about it. It lets me stay logged in to numerous different google accounts at the same time, without google getting confused about which tab is associated with which account. I concur with Paul, that it sounds like Comcast is not delivering the email for some reason, and with his other advice. The only further advice I'd give is to avoid using ISP provided email addresses for anything other than communicating with that ISP. They use it to reinforce vendor lock-in. Until there is some institution equipped and willing to vindicate subscriber rights (spoiler: there isn't), you are completely at the mercy of the carrier. You might consider, if you have the option, of switching carriers away from Comcast. I'm not claiming that either of their "competitors" is "better" in terms of their business practices, but "churn" is something that costs them money and they pay attention to. There is a fair chance that you can get one of (depending on whose service territory you live in) either Ziply or CenturyLink/Quantum fiber. Your only point of leverage with carriers is your option (if you have one) of not paying them money. They love your money, but they hate you. If you can credibly threaten to not give them your money every month, they might become more pliable when it comes to satisfying your technical support requirements. -- Russell Senior russ...@personaltelco.net On Mon, Jan 1, 2024 at 12:41 PM Paul Heinlein wrote: > On Mon, 1 Jan 2024, markcasi...@comcast.net wrote: > > > Here is my issue.

[PLUG] Unhappy hard disk disassembly
In my year-end tidying, I've been sorting out my various hard disk stockpile accumulated over the last couple decades. They went into separate boxes: IDE/PATA, SATA, SAS, and DEAD. This afternoon, I got around to taking apart the DEAD ones, partly for data security, partly for magnets and partly for curiosity and maybe harvesting precision bearings or motors. I had a stack of maybe 15-18 hard disks in the DEAD pile, mostly SATA, but a few IDE/PATA. Of those, about half had significant disk platter damage. I took some photos, which I have shared in the album linked here: https://photos.app.goo.gl/1MGJqAm7TdgixP5F6 I didn't bother to photograph the pristine-looking platters, so these are just the ones that took some damage. Some damage more dramatic than others. One side of a damaged platter was pretty much intact, so that's the only clean one you'll see in this batch. I handled them, and even washed/dried them off (with a lint-generating towel) so don't mind the specs. The disks look yellow due to the incandescent bulbs over the dining room table where I took most of these. The last couple pics are with some magnification, ether 10x or 30x, under my stereo dissecting microscope. One of those shows a particularly egregious gouge.

FYI, there is a musical gig getting ready to happen. Clint and I are here, but depending on who shows up, we might want to relocate. We have half a long table at the moment.

[PLUG] ANNOUNCEMENT: UnPLUG at Rose City Book Pub tonight!
Portland Linux/Unix Group General Meeting Announcement The response to my threat to talk about ancient tape recover was both insufficiently positive to do immediately and insufficiently negative to give up on altogether, but I'll save it for another month. If the continuing threat causes you angst, START WORKING ON A SUBSTITUTE, and I'll gladly defer. Partly to make commuting easy for Denis (who lives not far away), and because the most obvious alternative (Lucky Lab SE) is likely to be crowded with game players on what seems to be an organized game night, AND because it is going to be NOT WARM outside, enough not-warm to be unpleasant on the porch, I have arbitrarily picked Rose City Book Pub as a venue. Who: YOU! What: Un-PLUG: unsorted, on/off topic discussion by, for, and between us ... and anyone else within earshot Where: Rose City Book Pub, 1329 Northeast Fremont Street, Portland, OR, 97212 (probably inside, due to weather) When: Thursday, December, 2023 at 7pm Why: The pursuit of technology freedom Bio: all shapes and sizes Talk: yes, hopefully! Rules and Requests: PLUG is open to everyone and does not tolerate abusive behavior on its mailing lists or at its meetings -- Russell Senior PLUG Volunteer russ...@pdxlinux.org

Re: [PLUG] Network Security issue => ARP table cache
As long as we are talking about ARP, I want to mention that IPv6 does not use ARP. Instead, it uses NDP (neighbor discovery protocol) with some ICMPv6 multicast messages, and the "modern" iproute2 tool which works across ipv4 and ipv6 is "ip n", where n stands for "neighbour". >From the manpage for ip: neighbour - manage ARP or NDISC cache entries. Obviously, much additional reading is available, almost certainly more accurate than my cartoon version here. -- Russell Senior russ...@personaltelco.net On Tue, Dec 5, 2023 at 4:31 AM MC_Sequoia wrote: > For future reference for anyone playing along at home, if you discover an > dup ip addr listing in the arp table cache, you can just manually delete it > from the command line.

Re: [PLUG] Network Security issue
"Suspected threat blocked because of duplicate IP addresses on network." That would seem to imply that it saw multiple MAC addresses with the same IP address. That *might* happen if your laptop was plugged into a wire for part of the time, and connected by wifi for part of the time. Each of the laptop's interfaces will have its own MAC address, although DHCP should therefore give them distinct IP addresses as well. It *sounds* like a false positive and the proprietary "malware" software is just being dumb, but that's a completely wild guess and based on nothing.

Re: [PLUG] Network Security issue
Completely made up MAC addresses are common these days, particularly on mobile devices like iOS and Android, as a privacy measure.

Re: [PLUG] Network Security issue
I'd make a note of the mac address of the mystery device. What is running on the Buffalo router? Is it the vendor firmware or something like OpenWrt? If you have tools on the Buffalo, you have more options to track the device down. -- Russell Senior russ...@personaltelco.net On Mon, Dec 4, 2023 at 4:59 PM Dick Steffens wrote: > My wife has ESET malware protection on her Windows 7 machine.
