  • @elscallr I agree about the instance configuration, fixing that is the real solution
    My question was not about running something as another user, but about hiding the superadmin privileges from a single command I’d execute without switching users. However it is clear that something like that doesn’t exist so I’ll do the right thing and set everything to work with a new user





  • @astraeus yep, completely agree on the security issues, that is a mistake that should be fixed. But for the moment I confirmed that root is the only user, and every file and program in the instance can only be used by root (I just created a new user and tried to run the command with su -c but got a lot of permission denials and command not found)
    If I could hide or disable my own sudo permissions that would save me a lot of work, but I’m starting to think that something like that doesn’t exist 🙁



  • @Rustmilian yeah, already tried it. The problem is that all of the apps in the instance are only installed for the root user (e.g. python and all it’s libraries. So, when I use su -c all I get is a lot of command not found messages that would take a lot to solve. Besides I expect a lot more problems when the command needs access to some files and some processes (like a sql database) that would require me to do a lot of stuff to grant permissions to the new user. That would eventually work but given the work it requires I thought that some kind of “anti sudo” command or something like that could exist so I can still be the root user but pretend I am not a superadmin

    Forgot to mention that creating a new user brings a lot of problems because of how that machine is configured and all the tools that would need to be added the new user’s permission. In theory it would eventually work after some time working on it, but I’d like to know if there’s a way to do it without creating users (or if it’s impossible, so I can just go on with that only option)

    @astray yeah, that could be an option, but if more users exist in that machine then other processes might fail as that instance is part of a bigger cluster that has several processes running. It might not be a big deal, but checking that may still need some work. I’d prefer a way to do it without creating new users, if it exists





  • @Link @linux Yeah the kernel changes nothing, I might have to change to intel because I dont know what else to do at software level
    About the @ , I’m using my mastodon account to write all these posts and they are added automatically. Besides thats the best way for the posts I write in mastodon to appear as comments in lemmy clients. If they look weird to you it might be activitypub compatibility bugs but nothing too important :)

  • @Rustmilian @linux Just tried that but no change. iwconfig was not found but I installed it through the wireless_tools arch package. Also confirmed that the linux-firmware package was always been installed with the iwlwifi-8265-34 and iwlwifi-8265-36 files in the folder you said. When I ran the iwconfig wlan0 power off command, there was no error but the connection quality didnt change, so I didnt do the rest of the suggestions
    @Link commented they had the same issue but in the end decided that the solution was replacing the realtek card for an intel because the drivers just dont work. Im starting to agree, but still dont know how this issue didnt exist when I had fedora running




  • @Rustmilian @linux Thank you for your help! I did what you suggested and it fixed about 80% of the problem. I no longer randomly disconnect from the network and it is way faster than before, although download speed is still 8x slower than it was last week when I had fedora running instead of arch. I think I’m going to try more values for the 11n_disable parameter (there is no power management to disable), but even if it doesnt improve my machine is at least usable now. Thanks!
