  • I get the sentiment but defense in depth is a methodology to live by in IT and auto updating via the Internet is not a good risk to take in general. For example, should Crowdstrike just disappear one day, your entire infrastructure shouldn’t be at enormous risk nor should critical services. Even if it’s your anti-virus, a virus or ransomware shouldn’t be able to easily propagate through the enterprise. If it did, then it is doubtful something like Crowdstrike is going to be able to update and suddenly reverse course. If it can then you’re just lucky that the ransomware that made it through didn’t do anything in defense of itself (disconnecting from the network, blocking CIDRs like Crowdsource’s update servers, blocking processes, whatever) and frankly you can still update those clients anyway from your own AV update server which is a product you’d be using if you aren’t allowing updates from the Internet in order to roll them out in dev first, phasing and/or schedules from your own infrastructure.

    Crowdstrike is just another lesson in that.




  • I’m not against using Google, stack exhange, man pages, apropos, tldr, etc. but if you’re trying to advertise competence with a skillset but you can’t do the basics and frankly it is still essentially a mystery to you then youre just being dishonest. Sure use all tools available to you though because that’s a good thing to do.

    Just because someone breathed air in the same space occasionally over the years where a tool exists does not mean that they can honestly say that those are years of experience with it on a resume or whatever.


  • I’ve worked as an IT architect at various companies in my career and you can definitely get support contracts for engineering support of RHEL, Ubuntu, SUSE, etc. That isn’t the issue. The issue is that there are a lot of system administrators with “15 years experience in Linux” that have no real experience in Linux. They have experience googling for guides and tutorials while having cobbled together documents of doing various things without understanding what they are really doing.

    I can’t tell you how many times I’ve seen an enterprise patch their Linux solutions (if they patched them at all with some ridiculous rubberstamped PO&AM) manually without deploying a repo and updating the repo treating it as you would a WSUS. Hell, I’m pleasantly surprised if I see them joined to a Windows domain (a few times) or an LDAP (once but they didn’t have a trust with the Domain Forest or use sudoer rules…sigh).



  • Nah not for the big providers. The biggest problem is not having RUA for DMARC set up at all, set to None for the action or having an email in the RUA that will give a bounce message back to a sender (or not having DMARC at all in your DNS). The safe thing to do is set up SPF, DKIM and DMARC (correctly).

    You cant always control getting into a spam box from time to time if someone in your IPs /24 makes it onto popular spam databases but that’s very temporary but it is also very possible someone in your /24 is always on the lists. You can check yourself and there are both scripts and sites that will check most of the popular ones for you.

    /24 is a very popular CIDR to use for stuff like spam filtering or internet facing IPS.



  • Needing to use command line for some things that should be a right click, not supporting right click, ambiguities galore when looking at a package repository, odd defaults in packages that one really wouldn’t expect to have to check (e.g. Selecting RDP connection in a Remote app, but it defaults the security to something other than RDP?)

    Sounds like you’re using a GNOME Desktop. You should give KDE Plasma a try instead. KDE Plasma basically gives you a Windows-esq experience without trying to install something like GNOME extensions.

    For a regular user there’s not much point into going into the command-line anymore.

    there’s problems like Libre Office devs …

    Sure but there’s also alternatives. LibreOffice doesn’t try to emulate Microsoft Office and they never really have. They won’t even try to be compatible with MS Office but rather they do with OOXML which Microsoft created for other Office suites to be compatible with it but then just never supported it very well. Some alternatives do however. WPS Office is perhaps the most popular alternative for this that does try to be compatible with MS Office and emulate its feel and features but ONLYOFFICE is also a contender.


  • Just a heads up, if you use an AMD GPU, the drivers are built into the Linux kernel itself by AMD engineers (and others helping/supporting/contributing to the kernel like themselves). So you don’t even have drivers to install, unless you’re one of the 10 people that want to use AMD GPUs for Machine Learning. Then you’d do a quick install of AMD PRO (those are proprietary so that’s why they aren’t built into the kernel).




  • On the one hand LA county has a massive crime issue and the masks aren’t helping. On the other hand, even without masks they still had a crime problem anyway because LASD (almost $4bn budget) sucks at their jobs and there isn’t a lot of support of the current Sherrif from deputies that has been trying to fix them. LAPD ($2bn budget) basically only takes care of the main part of LA city proper itself.

    Where I live break-in response times are around 4 hours and anything under that is measured in days, if they show up at all.



  • It’s also difficult for developers to publish to Linux because of the wide variety of different Linux systems.

    I disagree there. The issue is that in Windows people bring over their own version of libraries they compiled on (the millions of .dll files) and you can even look in your Uninstall Apps settings where there’s a bunch of MS specific runtime bundles to see that’s even an issue in the MS ecosystem.

    In Linux, developers have relied on the library versions just being there. It is, I’d argue, the most compelling reason package managers basically had to come into existence. On the flip-side this can cause issues where there is some version on the system by the package manager that replaces another version. And something not a part of that package management system isn’t a part of those dependency checks and if they don’t put the libraries with the binaries…well it is just luck if you have them all or if other versions can support those library calls in the same way still.

    In Linux that is all those .so’s in /var/lib and stuff.

    You don’t really see many proprietary things using package managers and those that do are packaged by someone else and are in some sort of repo that isn’t part of the vanilla install because of legal caution.

    Companies that made their money on porting games to Linux prior to Proton basically causing them to shutter Linux porting would put their .so’s in with the game bundle themselves, just like you see happening in Windows when .dll’s are inside the actual program’s folders.

    However, the more that this sort of dependency management has become abstracted by development suites that take care of this for the developers, the less they understand about it.

    Flatpaks actually take care of this and it is one reason they are so popular. They figure out (well that’s a simplification) those library dependencies, sandbox the apps with those dependencies so the library paths don’t interfere with other flatpaks or the base system itself. People complain about this as a con because “the download is BIGGER” even though flatpak doesn’t install the same runtimes over and over again, so once they are there, the download may still be bigger but the installed storage isn’t.

    Anyway, yes Linus Torvalds complained about the “Linux fragmentation” issue but it was about DE’s not the state of the development ecosystem itself as I recall, though the rant is very old, so maybe I don’t remember all of it.

    Wider application support would be a start.

    Sure, but that’s not a Linux problem, that’s a developer problem. Linux supports application development just fine. It is a kernel and the surrounding ecosystem is the operating system after all. It is developers that don’t support it. That isn’t really something Linux in and of itself can effectively solve. Users have to increase and developers supporting applications for Linux will also increase. The classic Linux Chicken and the Egg problem but it is capitalism and that’s just going to be how it has to work.



  • I don’t know, I like using Fleet Commander with FreeIPA (where it stores the profile). You just spin up the template VM for whatever like-clients on the network you want to make default profiles for and make the changes, shut it down, checkbox the changes (the configurations and stuff) that you approve and let it apply the profiles across the network. Easier than depending on Puppet or Ansible playbooks IMO.

    I have had issues with SSSD as well though and it had to do with Kerberos tickets but I can’t remember what I did to fix it. We’d have to manually use kinit on each machine when it’d basically fall off the realm. I want to say it was a DNS issue but it was so long ago, I just don’t remember.

    We used to use Centrify for Linux and Solaris and it was easy using Access Manager to basically handle AD users and computers with Active Directory and had some GPO support (you could push config writes with GPOs for example and organize it all via OUs for example) but it would get a little wonky between trusts in the forest sometimes (in regards to zone management in Centrify) and they kept getting more expensive. Maybe they’ve fixed that stuff now but it was really simple to use and you could basically manage a lot through the AD and create group profiles in the Access Manager. I think the last straw was wanting to force us to license the entire suite regardless of whether we were using it or not. Personally, I never liked it because it wouldn’t use SSSD or kclient/nsswitch and if some service tried to join the realm/domain, it’d join using the same computer accounts and basically break the account since Centrify used its own client, so you’d specifically need to join the computer accounts via Centrify as a different name. It wasn’t detrimental or anything – just annoying that it was a problem at all. Also, sometimes the user cache database saved in specific users’ appdata that use Access Manager would corrupt from time to time and you’d need to manually delete it to use Access Manager. I’d hope they fixed that by now too though.

    All and all, I’m not saying Active Directory isn’t an excellent product because it is and I’m not saying that there is a 1:1 solution for Linux but I’m saying it that in my experience it isn’t terrible either with FreeIPA and products you can use with it. I definitely hated other 389 solutions prior to FreeIPA though.


  • For Linux user management you can just use an LDAP solution like FreeIPA. You can even tailor sudoer rules based on security groups, so like you can allow someone to reboot the server but not actually make configuration changes to system config files and what-not. It’ll also handle CA and PKI with smart card support and of course DNS. It has a web interface as well.

    a stack of 18650s

    (you probably already know) but this is common in a lot of battery packs. Batteries for power tools are good sources for the 18650s too. I never checked but I saw someone open a Tesla car battery and they look like a bunch of 18650s inside too.

    I refurbish my power tool batteries instead of buying new ones because it is so easy.


  • Having a NAT on a consumer router is indeed the norm. I don’t even see how you could say it is not.

    I never said NAT = security. As a matter of fact, I even said

    It was not designed for security but coincidentally blah blah

    But hey, strawmanning didn’t stop your original comment to me either, so why stop there?

    Let me tell you: All. Modern. Routers. include a stateful firewall.

    I never even implied the opposite.

    To Linux at least, NAT is just a special kind of firewall rule called masquerade.

    Right, because masquerade is NAT…specifically Source NAT.

    I’m just going to go ahead an unsubscribe from this conversation.
