  • I usually do Arch myself these days and spent many years with Gentoo. So I’m not too terrified of breakage!

    I am putting together a Linux distro strategy for my company. I am the MD of a very small IT company in the SW of England. I already have my office manager asking me to liberate her from Windows! I recently had a techie asking me to help his transition! This is organic stuff and not pushed down by me. The techie is a dyed in the wool Azure lover.

    I am used to being patient. It took me roughly five years to get a helicopter company that I worked for back in the day (late 1990s) to use DHCP properly - ie let them “roam free” and let DDNS pin them down. Sounds a bit ridiculous until you encounter “enterprise” grade nonsense.

    I have set up laptops with most of the usual suspects and tried them out. However, I have to comply with Cyber Essentials Plus which is a UK standard. It is fine but rather Windows n that 'centric. That means I need full disc encryption and anti virus (AV) and Secure Boot. I got away with ClamAV in the past but ideally I get cross platform and that means ESET for AV/web etc. I use the usual Linux FDE.

    I also need to join an Active Directory until I have got rid of AD! Oh and there is Exchange.

    https://cid-doc.github.io/ - AD and Evolution with the EWS addon for Exchange.

    So I dive in with Kubuntu after trying Rawhide and all sorts. Ubuntu is flexible enough whilst being stable enough for me. For example, Kerberos is screwed for the Firefox snap. I need Kerb for auth to my corp websites such as our wiki. Mozilla does a PPA - I dump the built in FF snap and use the Mozilla blessed PPA. All documented and all controllable in an enterprise sense.

    Closed In Directory (CID) is a configuration for Linux boxes joining into the MS world. Its a super piece of work, getting Samba, krb etc all working together well, and with a GUI. You can run scripts from your DC for that GPO feel with it.

    My needs are a bit more corp than your gaming shenanigans but my notes might help you decide what you want, what you really (really) want (zigazig … ahhhh!)

    Ubuntu PPAs are a bit like the AUR for Arch … well you have to decide what you really want. You could start from scratch: https://www.linuxfromscratch.org/


  • Bizarre article: “Recently, Linux-based firmware has emerged as a powerful alternative”

    I have a stack of Dell OS9 switches in my computer room - they boot BSD. I have sold and set up Dell OS10 switches - they boot Debian … on the control plane. To be fair they can run quite a few OS’s on the control plane. On both, you can switch to a shell (BASH) and fiddle with Ansible and the like or you stick with the usual interface.

    They are not glorified PCs! Frames and packets pass through some very fancy electronics and some very specialized memory (CAM - Content Addressable Memory) is employed for certain tasks. The manuals for these beasts run to 1500 pages.

    I also have a large fleet of pfSense and VyOS routers and a Mikrotik or two and a slack handful of Fortiwotsits, oh and a Cisco thing or two and some others. pfSense is BSD and the rest are Linux. The Fortis are a bit more like modern switches with their own rather odd and twitchy way of doing things, backed up with some fancy and not so fancy hardware.

    I have also played with all of the distros mentioned: Tomatoe/DD-WRT/OpenWRT and they are great for cheekying up a rather rubbish ISP provided router. They are also great for running on budget gear. They are basically superb for budget conscious consumers that are capable of reading some very decent docs. Prosumer is the term, I think.

    Anyway, this article is rather odd and is basically filler. The section titled: “Case Studies and Real-World Examples” is a contender for fluff of the month.




  • My wife’s laptop absolutely has to work. For some mad reason I decided on Arch for it. Actually a rolling distro is not so mad. You get the latest stuff and in general issues are fixed as quickly as a LTS jobbie or you get a work around in the forums or you dig out the source and a compiler. It’s no accident that the Arch wiki is an oft cited resource. Its not for everyone!

    I’ve been looking at a similar thing for my company and Kubuntu so far is my choice and I’ve already ditched the LTS bit. I need to run AV and the usual corporate bollocks to pass silly tick box exercises, so my options are rather limited.

    There is no perfect one size fits all distro, that’s what we have rather a lot of them to choose from - they rise and fall according to natural selection and not artifice. Imagine if all computers were sold with a free/libre OS or none at all and Windows or Apples were a paid for add on. Monolithic OSs are completely deluded about being able to cater for all, without some dreadful contortions.

    Anyway, back to the job in hand! If you want a LTS then you must accept older software or you use an LTS as a base and add newer stuff yourself. Most Linux distros allow you to run your own add-ons formally or informally. Gentoo has a rather nifty user patching mechanism for distro ebuilds and you can have your own ebuilds take over entirely. RPM and pkg distros can handle user packages and Ubuntu has PPAs too. I could go on. Also you can go off piste and put stuff into /opt and/or /usr/local!

    Please reconsider your use of the term “unstable”. I suggest you write down a list of your requirements and score them according to importance. Then grab a list of OSs and distros - all of them, don’t preclude Windows and Apples: they have their uses. Then score the OSs/distros against your requirements. The scoring might be in the form of a matrix (table). I suggest keeping it simple with a score of -1 to 1 for each item (-1=dislike, 0=neutral/whatevs, +1=like)

    Do a pilot project and see how that goes. Take your time. If it is for personal use then run your tests in a VM. Most modern hardware can easily run a VM or two. Virtualbox or VMware Worskstation or KVM (libvirt is a good effort)

    The choice is yours. Note that word “choice” - its very important.

    “I understand that Canonical has every right to make the decision about their product.”

    That seems fair. There are loads of distros available so why not try something else if you don’t like Ubuntu?

    Linux and other mainstream Unices such as FreeBSD or OpenBSD int al (that’s not something I ever thought I’d be able to say a few decades back) are not Windows or Apples or whatevs. You do you and not them!

    If Ubuntu fails to scratch your itch then move on. Debian is the upstream for Ubuntu so you’ll probably be fine with that instead. There is loads of documentation for Debian via the wiki etc and of course most Ubuntu docs will apply as well.


  • I’ve just moved my work PC from a cast off from a customer - it had a BIOS date stamped 2012, and was a rather shag Lenovo with a … Intel Core something and four GB RAM. Cheap though, ie free. I did wedge in a SSD to make it usable.

    I run KDE which isn’t known for being tiny and I have a Postgres DB and a few containers for experiments running. The new box is a i5 Intel G13 thingy - HP mini jobbie. Luxury

    To ensure that I am as disadvantaged as everyone else, I run ESET Endpoint AV and full disc encryption on it. It boots EFI and Secure Boot is enabled. I will pass a Cyber Essentials Plus audit (UK standard) without having to employ any misdirection. I’ve also read up on the US standards. The STIG for Ubuntu 22.04 is doable but my desktop is running 23.04 and 24.04 has just come out.

    I run my company and we have some customers who have some rather more stringent requirements than others. We also have our own standards.



  • They don’t need a new distro, unless they hire a lot of highly skilled packagers. I’d take say Ubuntu or OpenSuSE … but it would be RedHat with Oracle for the NHS - they just can’t help losing money.

    For my tiny company, I’m going Kubuntu … bear with … Ubuntu means:

    • Multiple “enterprise AV” are available (ESET and others)
    • Secure Boot
    • Full disc encryption is available

    Those boxes ticked gets you on the way in the rather naff enterprise security word of tick boxes. Without those - give up now.

    The K(DE) bit gets you a lot of configurability and its reasonably easy to get an environment out of the box that Windows users can get to grips with. Besides, I like KDE/Plasma.

    I then tack on this rather fine project: https://cid-doc.github.io/ for AD, SYSVOL, “Drive letter” etc integration. Evolution with EWS does email.

    My test machine is my desktop (it used to run Arch (actually), my laptop still does) - I started off with Kubuntu 22.04 and wired up all the above and then whilst in a Teams meeting kicked off the upgrade to 23.04 for a laugh. Sound stopped after a while because the kernel modules switched out. Anyway, all good after a reboot.

    Seeing as I am competing with something that has GPO, I’ll allow myself to use Ansible.

    PS - I should point out that an Arch box can run one of the ESET for Linux products OK (I have). You can get it to do secure boot and it can do FDE. So can Gentoo but I spent 15 years constantly fixing my Gentoo pets too.




  • I do IT security for a living. It is quite complicated but not unrealistic for you to DIY.

    Do a risk assessment first off - how important is your data to you and a hostile someone else? Outputs from the risk assessment might be fixing up backups first. Think about which data might be attractive to someone else and what you do not want to lose. Your photos are probably irreplaceable and your password spreadsheet should probably be a Keepass database. This is personal stuff, work out what is important.

    After you’ve thought about what is important, then you start to look at technologies.

    Decide how you need to access your data, when off site. I’ll give you a clue: VPN always until you feel proficient to expose your services directly on the internet. IPSEC or OpenVPN or whatevs.

    After sorting all that out, why not look into monitoring?


  • I think we might be writing at cross purposes. The system you had for your mum obviously worked effectively for you and that is the important thing.

    POTS provide(s|d) a fixed point of reference - your address is registered against the number for 999 etc; it provides power for a handset or device; Its been like that for a lot of decades! These are cast iron guarantees. A POTS line has guarantees, enshrined in UK law, that mobile etc does not have. POTS is circuit switched (well it was) which means there is a physical path between the ends for the duration of the conversation.

    So, by old school, I mean that you currently have important guarantees about telephony in the UK that will evaporate in future. In 2025 or so, we in the UK will have finished migrating from our old school POTS copper lines and will enjoy our smart new SoGEA lines instead. Single Order Generic Ethernet Access. Instead of an emulated circuit switched line we will use VoIP across the entire country. Nothing wrong with that but it probably won’t have the guarantees that POTS had.

    Red Care is no more - BT have dropped it on the floor as of Feb this year which may indicate that things are not well with our future comms promises. The general system that Red Care was one product of is still available.

    This is the important point: Promises (in law) that we used to be able to rely on for comms may (will) be binned.


  • In the UK at least, the POTS (Plain Old …) copper phone lines carry an electrical current as well as signals and can power the handset. There are certain guarantees about this so that in an emergency your phone will still work so you can dial 999 (our original emergency number) or 112. Our fire regulations require something like 30 minutes before things should start failing. In the real world, you get out immediately and use your mobile.

    We have an emergency alarm monitoring system used by businesses. Its generally known as “Red Care” which was a brand run by BT (British Telecom). You have a small device connected to a phone line (and powered by it) and it will monitor your fire detectors and building access control systems and a 24 hour manned monitoring centre will notify you in the event of an emergency. Nowadays, these devices will use your wifi and internet connection. Sometimes: old school is best.



  • Which distro do you use? Ubuntu, Debian, Arch and Gentoo have packages and I’ve no doubt that most others do too. On Linux you should not have to go to random websites and download stuff and faff around - use the built in distribution packages. If you are not sure what you’ve got try this at a command prompt and read the output:

    $ cat /etc/os-release
    
    

    As a last resort, you can run tcpdump on nearly anything and dump to .pcap, transfer that and then open that in Wireshark. Note that modern Windows has a OpenSSH client and server available so getting files around via scp is a doddle. Windows can even do NFS too and there is of course Samba - but CIFS/SMB can be tricksy.
