Friendly greetings to all! ๐ŸŒŽ๐ŸŒ

What's New At MetalVPS?

  • Debian Linux sid unstable seems to have been installed (replacing the excellent Proxmox) on the new MetalVPS EX100 Intel i9-12900K Node at Hetzner Helsinki.

  • MetalVPS hopes to keep both the i9-12900K Node and Debian sid for a long while.

  • Yabs

  • Want a free, traditional, bare metal Debian sid shell account? Maybe with sudo? ๐Ÿ‘ With all node resources shared, fair use? ๐ŸŽ‚

Network Specs

  • 1 Gbps unlimited, fair use

  • 1 x IPv4

  • 1 x IPv6/64

Who?

  • MetalVPS is a project of @Not_Oles a/k/a Tom Miller a/k/a the cluelessโ„ข guy.

Where?

  • MetalVPS currently has Nodes in Helsinki, Finland ๐Ÿ‡ซ๐Ÿ‡ฎ and in Fremont, California USA. ๐Ÿ‡บ๐Ÿ‡ธ

  • The Fremont Node is not included in this offer.

Why?

  • Why not? It's fun to play with and learn about servers, operating systems, and the internet. :)

  • @Not_Oles uses very little of his MetalVPS servers' capacity. It's better to offer the extra capacity to others than to waste it.

Congrats!

These congrats are transferred from the Fremont Node. More congrats will be added as people begin to use the new Helsinki Node.

Warnings!

  • Cluelessโ„ข administrator! ๐Ÿ˜€ @Not_Oles frequently messes up! ๐Ÿ˜ฑ

  • @Not_Oles is especially cluelessโ„ข about Debian since he is a Debian noob. ๐Ÿค—

  • Hey! This Node runs Debian unstable! ๐Ÿคฉ

  • Sometimes trusted MetalVPSians might or might not get sudo. ๐Ÿ™ˆ๐Ÿ™‰๐Ÿ™Š

  • MetalVPS has no billing panel and no server control panel. It's all command line until you install a GUI or activate whatever pre-installed GUI you want. ๐Ÿ†•

  • MetalVPS has no onboarding and no knowledge base. โ™’๏ธŽ If you want to make an LXC or KVM VPS, please be willing to research about how to do it on the command line.

  • Account delivery might take awhile! ๐Ÿ˜ด

  • Accounts subject to cancellation at any time without advance notice! ๐Ÿ’ฅ

  • No warranty, to the extent permitted by applicable law. No service level agreement. Not for business use. Intended especially for computer learning and fun! ๐Ÿค‘

  • White Hat stuff only, please! No copyright violations, please. ๐Ÿ‘

  • @Not_Oles tries to keep the system updated. Frequent maintenance reboots are almost guaranteed! ๐ŸŒบ

  • Please make your own redundant, offsite backups! It's easy to download or sync or clone your backup to a safe place. Please also make sure that you actually can restore from your backups! Please think of your MetalVPS account as ephemeral! It might blow up! We or you might reinstall the Node! ๐Ÿคฆโ€โ™‚๏ธ

  • MetalVPS.com is not a project of lowendspirit.com, lowendtalk.com, hetzner.com, or of Cloudie Networks, LLC. ๐Ÿ‘จโ€๐Ÿ’ปโ€‹

  • Other MetalVPSians can see your account name, some of the processes you are running, and much other information. So, please do not put confidential information on the server. ๐Ÿค”

Bug Report

  • Following the upgrade to sid, reboots sometimes fail to complete until after power is reset. Following power reset, the Node reboots successfully. The issue happened on multiple servers, so it seems not to be a hardware problem.

  • Fortunately, after a successful reboot, the server seems stable. A yabs run just now on sid is shown below.

  • The problem might be with dbus. Here is some log output for a failed reboot. The errors at the end seem similar to Debian Bug 877642.

Installed Stuff

  • We're just beginning on this Node.

  • So far, gcc, git, lxc, qemu-kvm, zsh, and more are installed. Additional configuration still is required, but MetalVPSians eventually should be able to compile, to create unprivileged LXC containers, and (if added to the kvm group) to create KVM virtual machines.

  • Plans include installing Docker and Nix. Plus code-server, oksh, Xv6, plan9port, LAMP stack. Plus more. If you want something, please let us know! :)

How To Sign Up

  • Please post in this thread. Only if necessary, please PM @Not_Oles or use the email on @Not_Oles profile.

  • If you have a new account, please introduce yourself in your post. Please tell us what you plan to do with your account. Please include your ed25519 ssh public key.

Support

  • Please post in this thread. Only if necessary, PM or use the email on @Not_Oles profile.

  • Additional communication channels might be available via Signal App, Discord, Jitsi, etc.

What People Are Saying

    Checking on the Qemu install produced a fun surprise!

    The Debian Wiki says:

    Installation
    The QEMU emulator is packaged as qemu

    $ sudo apt install qemu qemu-utils qemu-system-x86 qemu-system-gui

    Our cluelessโ„ข Administrator tried to install qemu and qemu-kvm.

       949  Note, selecting 'qemu-system-x86' instead of 'qemu-kvm'
       950  Package qemu is not available, but is referred to by another package.
       951  This may mean that the package is missing, has been obsoleted, or
       952  is only available from another source
       953  
       954  E: Package 'qemu' has no installation candidate
    

    Looking at packages.debian.org's page for qemu-system suggests that qemu-system might be the right package to install. It looks like we also need at least the qemu-utils package. Looking at the source package it's not immediately obvious to me what additional binary packages might need to be installed.

    Having had the experience of compiling qemu from source and running it on Darkstar, it seems easier to do the compile than to figure out the Debian packages. But it's fun to learn a little about the Debian package system.

    Oops! Sorry!

    Please continue to check everything carefully and please continue to let me know about anything else you find. I wanted to go through everything that was done to set up LXC on the Fremont server and write it up while adding to Helsinki configuration. But I am slow.

    I may setup several services like code-server/postgrse/mongodb/minio and more ,I would like to keep them sepereted ,
    then I can just replace the broken container When I mess up something.

    Thanks @subenhon! I see you are a member of the everything-in-a-container group. :)

    I should go make a container. Maybe I will sometime before too long.

    Want to run a yabs inside one of your containers? And post the results? When you have time, no rush.

    I hope everyone gets the servers they want!

    @subenhon Wow! That looks great! I'm impressed that the Geekbench 5 score is so high. The single core score on the Node was 2126. And your container scores 2106. That's only 20 points virtualization penalty.

    If you have time, could you please post the commands you ran to create the container? Thanks!

    Hey @subenhon!

    Thanks so much! This is terrific! I spent a short time with the linuxcontainers.org instructions but I didn't get all the way through the systemd stuff. I have to look at that some more. Then, probably I will have some more questions.

    @subenhon said: subenhon@sid:~$ #add x access to home before start the container or some error occurs
    subenhon@sid:~$ chmod +x $HOME

    Yeah, I see the result of the chmod:

    notoles@sid:/home$ ls -l
      [ . . . ]
    drwx------  6 notoles    notoles    4096 Feb 16 03:15 notoles

    I am trying to figure out.

    Add an ACL is another option.
    I remove the x access from my home directories, then set ACL for the directories, the container start success.

    Maybe icanhazshel.com is not too shallow! After all, Cloudflare did buy icanhazip.com. Maybe Cloudflare would buy icanhazshel. If not Cloudflare, then Akami for sure! ๐Ÿ’ฐ

    Hi @subenhon!

    Cool, thanks! I have to try this! It's new to me!

    Was the systemd-run command accidentally out of place in your post, like maybe a cut-and-paste error? Should the command sequence be as below, with the "systemd-run" command moved below the output from ls?

    Thanks again! Best wishes!

    Tom

    It is not a cut-and-paste error.
    I paste multi-line command in terminal , then the console output was print after the last command line.

    chmod 700 $HOME
    setfacl -m u:165536:x $HOME
    setfacl -m u:165536:x $HOME/.local
    setfacl -m u:165536:x $HOME/.local/share
    ls -al /home/
    systemd-run --unit=my-unit --user --scope -p "Delegate=yes" -- lxc-start -n ubuntu -F

    notoles@sid:~$ pwd
    ls -a
    echo foo
    /home/notoles
    .              .bash_logout  .cloud-locale-test.skip  .local    .wget-hsts
    ..             .bashrc       .config                  .profile

    foo
    notoles@sid:~$ 
    

    Wow! Honestly, I didn't know that could be done! I don't think I ever tried to paste a multi-line command. If somebody asked me, I would have imagined the shell would execute the command which is the first line that was pasted and then the remaining two lines of the paste would not be executed.

    Sometimes I've done multi-line commands by using a backslash prior to the return. I guess what's invisible in the line breaks in the three line command paste somehow must be equivalent to the backslash-return. Or maybe equivalent to a semi-colon like in a single line with multiple commands.

    When I searched for "how does the shell execute a multi-line paste," Google pointed me at https://stackoverflow.com/questions/6713056/how-do-i-paste-multi-line-bash-codes-into-terminal-and-run-it-all-at-once

    I tried to dump the paste into od attempting to see everything that was inside the paste. I didn't get that to work. How can one see what's actually being pasted, including the "invisible" characters?

    Isn't it more to do with how the terminal pastes the text to the shell.

    In the past, it would just paste the text as in and the shell would execute whatever it got (not knowing if it came from a paste or real keyboard input) - this was actually quite annoying when you inadvertently pasted multi-line commands that you didn't intent to.

    Nowadays most terminals seem to use bracketed paste mode where the shell is at least aware that it came from a paste, and the commands only get executed when you press return again (at least that's what I get with xfce terminal).

    BTW, xfce terminal is also quite helpful now in that it warns you by default when pasting multi-line text into a terminal.

    @cmeerw

    Thanks for your insight!

    Quoting from the link you posted:

    Bracketed Paste Mode

    When bracketed paste mode is set, pasted text is bracketed with control sequences so that the program can differentiate pasted text from typed-in text. When bracketed paste mode is set, the program will receive: ESC [ 200 ~, followed by the pasted text, followed by ESC [ 201 ~.

    I think (but I am not sure) my Chromebook is giving me hterm, into which I sometimes am pasting. The hterm will be connected via ssh to some remote shell, into which the paste goes. The remote shell often is running somebody else's highly variantly configured vi/vim. Occasionally I have seen sequences similar to ESC [ 200 ~ or ESC [ 201 ~. I will have to pay more attention next time this happens.

    Since both @subenhon and me were able to paste and run sequences of commands, maybe that's what's expected nowadays. At least on Debian.

    It's nice to see you here again! I hope you enjoyed your trip to the US!

    I hope this new EX100 server isn't going away any time soon, unlike some of the others I have had recently. If you want an account, please feel free to let me know.

    Thanks again!
