  • People still working in IT, thoughts on IPv6?
  • Another thing that makes no sense is if my ISP provided prefix changes -which it will- this affects the IP addressing on my local network. Ain't noboby got time for that if you're managing a company or having anything other than a flat home network with every device equal.

    IPv6 is just people shouting NAT BAD, but frankly having separate address ranges inside and outside a house is a feature. A really really useful feature. Having every device have a public IP6 address I'd an anti-featute.

  • People still working in IT, thoughts on IPv6?
  • On my local network I want governance over my devices. I want specific firewall rules per device, so I can, for instance, block YouTube only on the kids devices. I want this to be centrally managed, so configured on my opnsense router. I want all devices to use IP6. Unfortunately none of this is possible.

    To setup firewall rules I need DHCPv6, not SLAAC so my IPs on my local network that I manage are well known and fixed. Android devices don't support DHCPv6. And the designers of IP6 were daft enough to set the priority of IPv4 above that of their new protocol. So basically if you have any IPv4 addresses on a device, they'll be preferred by basically all operating systems - because that's what the spec says. So you can't run dual stack in a meaningful way.

    TL;DR: IPv6 on a local network has not been thought through at all even though it's incredibly old, it's really immature.

  • What Was Your Worst Experience Moving?
  • I've lived in 14 different houses. I can't remember any of the moves being particularly bad. Hard work, yes. Have had a couple of sofas not get through doors. Worst related thing was moving into first unfurnished place and assembling the new wooden bed on day 1 with a manual screwdriver that wrecked my hands and left me exhausted. Next day I bought an electric screwdriver and it's remained one of my top purchases of all time.

  • [Question] IPv6 SLAAC and firewall rules
  • It's nothing to do with static assignment of a prefix from my ISP, I have that. It's to do with static assignment of IP addresses within my own house! Use DHCP and android will not use it; use SLAAC and I have no control over IP addresses and therefore cannot set up sensible firewall rules per device.

  • CDs are better than vinyl and most people listen to music on systems that sound dreadful

    CDs are in every way better than vinyl records. They are smaller, much higher quality audio, lower noise floor and don't wear out by being played. The fact that CD sales are behind vinyl is a sign that the world has gone mad. The fact you can rip and stream your own CD media is fantastic because generally remasters are not good and streaming services typically only have remastered versions, not originals. You have no control on streaming services about what version of an album you're served or whether it'll still be there tomorrow. Not an issue with physical media.

    The vast majority of people listen to music using equipment that produces audio of poor quality, especially those that stream using ear buds. It makes me very sad when people don't care that what they're listening to could sound so much better, especially if played through a hifi from a CD player, or using half decent (not beats) headphones.

    There's plenty of good sounding and well produced music out there, but it's typically played back through the equivalent of two cans and some string. I'm not sure people remember how good good music can sound when played back through good kit.

    PGP key discovery for Email - WKD

    I've run my own email server for a few years now without too many troubles. I also pay for a ProtonMail account that's been very good. But I've always struggled with PGP keys for encrypting messages to non-Proton users - basically everyone. The PGP key distribution setup just seemed half baked and a bit broken relying on central key servers.

    Then I noticed that email I set from my personal email to my company provided email were being encrypted even though I wasn't doing anything to achieve this. This got me curious as to why that was happening which lead me to WKD (Web Key Directory). It's such a simple idea for providing discoverable downloads for public keys and it works really well having set it up for my own emails now.

    It's basically a way of discovering the public key of someone's email by making it available over HTTPS at an address that can be calculated based on the email address itself. So if your email is name@example.com, then the public key can be hosted at (in this case) https://openpgpkey.example.com/.well-known/openpgpkey/example.com/hu/pmw31ijkbwshwfgsfaihtp5r4p55dzmc?l=name this is derived using a command like gpg-wks-client --print-wkd-url name@example.com. You just need an email client that can do this and find the key for you automatically. And when setting up your own server you generate the content using the keys in your gpg key ring using env GNUPGHOME=$(mktemp -d) gpg --locate-keys --auto-key-locate clear,wkd,nodefault name@example.com. Move this generated folder structure to your webserver and you're basically good to go.

    I have this working with Thunderbird, which now prompts me to do the discoverability step when I enter an email that doesn't have an associated key. On Android, I've found OpenKeyChain can also do a search based just on the email address that apps like K9-Mail (to be Thunderbird mail) can then use.

    Anyway, I thought this was pretty cool and was excited to see such an improvement in seamless encryption integration. It'd be nicer if on Thunderbird and K9 it all happened as soon as you enter an email address rather than a few extra steps to jump through to perform the search and confirm the keys. But it's a major improvement.

    Does your email provider have WKD setup and working or do you use it already?

    [Question] IPv6 SLAAC and firewall rules

    Given there's been a bit of talk about IPv6 around here recently, I gave it a really good shot at implementing this past week. I spent 3 days getting up to speed, reading loads and trying various different things. But I am now back to IPv4 only because I just can't get IPv6 to do what I want and no amount of searching has made me think what I want to do is even possible.

    Some background about the IPv4 network I run at home: I run opnsense on a Proxmox server. I have a few services publicly available using port forwarding. I run several VLANs for IoT, VoIP, Cameras etc. I use a bunch of firewall rules that are specific client devices on the network. So for example I have a rule that blocks youtube from the kids tablets and the TV. I have a special rule around DNS for the wife as she doesn't want to use the pihole blocking features. These rules are made possible because the DHCP server is set to give them a fixed IP and I can create a firewall alias and rule based on that.

    None of these things on my existing network are particularly difficult to configure, they run really well.

    What I want from IPv6 is:

    1. All devices to use IPv6 including android devices.
    2. To have the same firewall rules configured and not have them be easily bypassed.
    3. To use privacy addresses as I don't want to make every device uniquely trackable over the internet.
    4. To be able to cope with changes to the ISP provided /48 prefix seamlessly.
    5. Have internal DNS make accessing intranet devices easy.
    6. To ensure the privacy of individual devices on my network by avoiding individual device tracking.

    What I've tried:

    1. Using DHCPv6, but this excludes android devices. So that's out.
    2. Using a NAT (to avoid tracking of individual devices) and fd00/8 addresses, but this is pointless as those addresses are lower priority than IPv4 (FFS!)
    3. SLACC just seems a non-starter.

    Additional: I don't think I have a problem with "thinking about it all wrong for IPv6". I may have a skill issue, hence this question.

    As far as I can tell to achieve requirement 1) you must use SLAAC. SLAAC without privacy extensions doesn't allow for 6).

    Changes to external ISP prefix assignment impacts MY INTERNAL NETWORK (this just seems insane). And as far as I can tell there's no easy way around this, especially if I have static addresses configured for servers which would (if using SLAAC) have to be manually configured.

    I can't see how DNS would be updated either, either Unbound running on Opnsense, or to the pihole. If I go for SLAAC with privacy extensions and I keep paying for a static IP (v4 & v6) to my ISP then I can't implement any firewall rules for specific devices as devices will change their IP regularly. And its even worse if I don't pay for a static IPv6 prefix.

    I don't think anything I'm trying to do is particularly strange or unusual but 26 years after its introduction I don't see that IPv6 can meet these requirements. And one of the leading firewall routers, especially in the homelab doesn't have answers to these questions either.

    Can you suggest a way to meet all 6 requirements I have with IPv6?

    Moving to Helix, am I an idiot?

    Ok, I've cracked. I have a nice pedal board and I can get some nice sounds from it. But I'm selling almost all of it and moving to Helix. Keeping a rams head muff and blues driver. But the expandability, versatility, simplicity of setup and no need to worry about patch cables, power supplies etc..

    Am I going to regret it?

    Spent 7 hours trying to fix my iredmail server

    I noticed that I wasn't getting many mails (I need better monitoring), and discovered that my iredmail server was poorly.

    I have spent far too much time and energy on getting it back and working these past few days, but I've finally got it back up and stable.

    Some background: I've had iredmail running for probably going on 6 years now and have had very few issues at all. It runs on an Ubuntu VM on Proxmox and originally was running in the same VM on ESXi (I migrated it over). I haven't changed anything to do with the VM for years other than the Ubuntu LTS updates every 2-3 years, it's always been there and stable. I occasionally will update the Ubuntu OS and iredmail itself, no problems.

    Back to the problem... I noticed that Postfix was running OK, but was showing a bunch of errors about clamav not being able to connect. Odd. I then noticed that amavis was not running and had seemed to just die. I couldn't find any reason in any log file. Very strange. Bunch of hunting, checking config file history in the git repo. Nothing significant for years.

    Find that restarting the server got everything back up and running. Great, lets go to bed.... Wake up next morning to find that amavis was dead again - it only lasted about 40 mins and then just closed for no reason. Right, ok, time to turn off clamAV as that seemed be be coming up a bit wheilst looking, follow the guide, all is well. Hmm, this seems to be working, but I don't really want clamav off. A whole bunch of duck duck going and I still couldn't figure out a root cause.

    And then it clicked, the thing that was causing amavis to close was that it was running out of memory and it was being killed. Bump the memory up to 4GB and re-enable everything as it originally was and.... it seems to have worked. Been going strong for over a day now.

    I don't know what it was that's changed recently which has meant the memory requirements have gone up a bit, but at least it's now fixed and it took all of 2 minutes to adjust.

    The joys of selfhosting!

    What are your top 3 purchases of all time?

    There's 3 things that really stand out for me that I would say made a massive difference to my life:

    1. Cordless screw driver. Bought the day after building a flat pack bed with a crappy screw.driver that just shredded my hand. Thought it was frivolous at the time, but I've used it so much since. It's light, small enough to fit in my pocket and good for 90% of DIY tasks.

    2. Tassimo coffee machine. Bought it 9 years ago, use it every day. Nice quick easy coffee. What's not to like.

    3. My first DSLR camera. It was a Nikon D50 back in 2005/6 and it sparked my interest in photography to this day. It gave me a hobby I can take lots of places and do it alone or with others. I never loved the D50 camera itself, but I did get some really nice shots with it

    Thank you for the help yesterday. This is the cable I need to fit through a breeze block wall

    Thank you for the replies yesterday about my drill. I think I'm going to get a cheap corded SDS drill and some big bits. This is what I need to feed through the wall and there is no way to detach the cable from the camera and feed it the other way. I know it needs to be weather shielded, but this is a mad amount of connectors!

    Is this a hammer drill?

    The icon is a little different to what I've seen on others and I don't know how to tell otherwise. I have a job that involves drilling through a breeze block wall about 20cm and I don't want the expense of buying an SDS if I can help it.

    This drill was given to me a long time ago, hence not knowing what I have here.

    Thanks!

    NPD: One Control White Loop

    It's not the most exciting pedal in that it's just a clever switch, but I do like the possibilities it gives.

    It has two switchable loops. In one loop I have my Diezel VH4-2 working as a preamp and in the other I have my Peavey Classic's pre amp. This allows me to switch between which preamp I want to use whilst also keeping my delay and modulation effects in the FX loop - post preamp.

    Guitar goes in to the input. Red loop sends to the VH4 and returns from the VH4 preamp output. Green loop sends to the front of the amp and returns from the FX loop send. That's the two preamp loops. The left switch toggles between each loop and the right switch bypasses both loops, which in my case means I have no preamp as the signal goes straight to the FX return via the delays - so I'll keep the right switch always on.

    Then the output of the pedal goes to the modulation and delay pedals and then to the amp's FX return.

    Been playing over 25 years and just booked my first ever guitar lesson.

    I got my first guitar in about 95 and have been totally self taught. I stagnated massively for around 15 years in the middle when I infrequently played then got frustrated all I could do was some Nirvana power chords.

    Started playing again around 5 years ago and had my guitar professionally setup - what a world of difference that made! I've made decent progress since but it's still all just the odd riff or solo here and there and there's a lot I can do a lot better. Using YouTube videos is only getting me so far and some 1 on 1 I hope will do the trick.

    My wife started taking piano lessons and it inspired me to do the same for guitar. I'm sure it will be helpful even if they're going to rip my technique up and start again.

    Have you had lessons or are you self taught? What helped the most for your playing?

    Guitar amp interference.... A Rant and a happy ending

    I have just spent almost 5 days trying to rid the interference noise (and at one point the radio) from my speakers that started when I setup my new Behringer audio interface.

    Signal chain: Peavey Classic 20 MH -> XLR -> Audio Interface -> NAD hifi amp -> speakers.

    I must have tried at least 20 different things, so many youtube videos, including complete rewire of pc cables, usb, power cables. Different power outlets, with and without the UPS, extension cables from different floors of the house, turning off the tumble dryer, removing smart plugs, different cables, different usb ports, turning everything but the amp and interface off. Bought a noise canceling usb (ifi Defender+)- made things maybe a bit better when unpowered, made things worse when powered. So much crawling around under my desk! It was only an issue when the XLR was connected from my guitar amp, whether the amp was on or not - XLR unplugged PC audio was fine. Thought I'd try a different power cable to the amp - unplug the existing one and all hell break loose - SO MUCH NOISE AND INTERFERENCE!! Give up on the power cable idea. Then I unplugged the XLR and decided to try the headphone output of my guitar amp in to the interface. Whilst reaching around the back of the amp I see a small switch labelled "ground lift". Press it. Problem solved! Almost no noise. If I had happened to have that pressed when I bought the amp over a year ago I'd have had no problems. FFS!

    And now the ifi Defender+ does work and has made everything perfectly quiet when nothings playing. No more annoying noises when I move the mouse with a fuzz pedal on. Really nice, so a pretty good result overall, but so much effort!

    So remember kids, if you have a noise issue, check if your equipment has a ground lift button. I didn't see a single YT video that mentioned ground lift and I didn't even know they existed or that my amp had the button even after I was sure it was a ground loop issue.

    New Player Strat

    A Player strat in black with maple neck. So far I'm pretty impressed. The neck is nice, the back is satin and the fretboard is glossy, but not sticky like I thought it might be. The electrics all seem high quality. Fit and finish all excellent and almost as good as my PRS SE. Came setup with the bridge very floating and the 9 gauge strings old and corroded, but whatever they were coming straight off either way.

    I've already modded it to end up with the guitar I really wanted.

    New single ply black pickguard, decked the trem, tightened the truss rod, and a new set of GHS Gilmour strings.

    Now I'm very happy. I just love looking at it as much as playing it.

    PRS SE Custom 24 in Bonnie Pink

    Thought I'd share what I think is one of the most beautiful guitars I've seen: my PRS SE Custom 24 in bright Bonnie Pink. The light was catching it quite nice this evening.

    This thing plays as good as it looks. The neck is really nice, the frets and edge of fretboard are like butter, the trem is really nice with a push in bar. The high fret access is just superb. I love the pickups that have some great bite, but clean up with volume and tone adjustment. The split coil setting, although not perfect adds a lot of versatility so I dont often want to swap guitars just for some single coils - well, most of the time.

    Only criticisms would be I think it should have some with locking tuners, but as a £90 add on I can see why they did it to keep the cost down - having since added them I really like the PRS locking system.

    The pickup selector switch I find to be quite out of the way and the trem bar gets in the way if wanting to switch mid song. A LP is hard to beat in this regard.

    Overall a definite 9.8/10, very highly recommended.

    Upgraded Proxmox 7 to 8

    This was a very nerve racking experience as I'd never gone through a major version Proxmox update before and I had spent a lot of time getting everything just so with lots of config around disk and VLANs. The instructions were also a big long page, which never fills me with confidence as it normally means there's a lot of holes to fall in to.

    My initial issue was that it says to perform the upgrade with no VM's running, but it requires an internet connection and my router is Opnsense in a VM. Thankfully apt dist-upgrade --download-only, shutdown the Opnsense VM and then apt dist-upgrade did the trick.

    A few config files changed and I always hate this part of Debian upgrades, but nothing major or of importance was impacted.

    A nervous reboot and everything was back up running the new Proxmox with the new kernel. Surprisingly smooth overall and the most time consuming part by far was backing up my VM's just in case. The upgrade itself including reboot was probably 15 mins, the backups and making sure I was prepared and mentally ready was about an hour.

    Compared to upgrading ESXi on old hardware like I was doing last year, it was a breeze.

    Highly recommended, would upgrade again.

    Current state of the board

    It's been a long time in the making, but this is the happiest I've been with my board for a while.

    Signal chain: TU2 -> Blues Driver -> Vox Valvetone -> Diezl VH4-2 -> Wampler Pinnacle Deluxe v1 -> Wampler Pantheon -> EHX Rams Head Big Muff -> Mooer E-Lady -> Front of amp

    FX Send -> TC Electronic Flashback 2 -> EHX Oceans 11 -> FX Return.

    Running it all in to a Peavey Classic 20 Mini Head and a Harley Benton 1x12 cab with Vintage 30 speakers. The little red pedal is plugged in to the amp to toggle the channels (clean / OD) and the boost (on / off).

    Considering it's by far and away the biggest pedal on the board, the VH4-2 probably gets the least amount of use. But what it does is so unique that I'm not getting rid of it.

    The Oceans 11 is my most used pedal as it's never off. Otherwise I use the Pinnacle the most. It has such a good tone that reacts to the volume knob on the guitar so well. I find I can do almost any OD / distortion sound I want from it.

    The Pantheon, BD2, Valvetone and Rams Head all do their particular thing that the amp and Pinnacle can't. So even though there's a lot of drive pedals here I don't feel like there's much overlap at all. It means I can play Gilmour one minute, then Tool the next, Van Halen another and Clapton another.

    Stuff no longer on the board: TC Electronic mojomojo (too similar to other things), Boss DS-2 (not my kind of sound these days), Behringer noise gate (turned out my noise issues were caused by a Boss RC1), Behringer CS400 compressor (I want to like it and maybe I'll put it back on but I haven't been able to get what I want out of it).
