Free Alpine Linux Shell Accounts

Not_Oles · December 2022

Update: Sorry, but this wonderful server has been returned to @Cloudie. I hope everyone gets the VPS they want! Best wishes! -- Tom a/k/a @Not_Oles

Friendly greetings to all! 🌎🌍

What's New?

IPv4 Ping Monitor
IPv6 Ping Monitor
- Alpine Linux seems to have been installed on the MetalVPS antique Intel node at Hurricane Electric Fremont-2.
- Want a free Alpine shell account? Maybe with sudo? 👍 With all node resources shared, fair use? 🎂 Right now plenty of server resources are available because only a few people are using the Fremont node.

Fremont Node Specs

Server: Intel S2600GZ
CPU: 2 x Xeon E5-2630L v2, 2 x 6 cores = 12 cores = 24 threads
RAM: 32 GB DDR3 ECC (upgrade to 64 GB expected this month)
Hard Drive: 1 x 500 GB SSD, 2 x 1 TB HDD
IP Addresses: IPv4/28, IPv6/48
Connection: 1 GBit/s port
Bandwidth: Fair use
Datacenter: Hardware rented from Cloudie Networks, LLC inside Hurricane Electric Fremont 2, Fremont, California USA 🇺🇸
Node OS: Alpine Linux 3.17 edge! 🤩 NetBSD might or might not be coming soon! ❤️
VM OS: Whatever you install!

Who?

MetalVPS is a project of @Not_Oles a/k/a Tom Miller a/k/a the clueless™ guy.

Where?

MetalVPS currently has nodes in Falkenstein, Germany 🇩🇪 and Fremont, California USA. 🇺🇸
This thread is for the Fremont node. 🇺🇸
The Falkenstein node has its own offer thread.

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!

Warnings!

Clueless™ administrator! 😀 @Not_Oles frequently messes up! 😱
@Not_Oles is especially clueless™ about Alpine since he is an Alpine noob. 🤗
Hey! Fremont runs Alpine 3.17 edge! 🤩
Sometimes trusted MetalVPSians might or might not get sudo. 🙈🙉🙊
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. 🆕
MetalVPS has no onboarding and no knowledge base. ♒︎ If you want to make an LXC or KVM VPS, please be willing to research about how to do it on the command line. 🥰

So does Darkstar fade in the dark
While Alpine starts to shine?
If true then my day turn sad,
Though one hopes it won't be so bad.

It's admin's call really, a decision not so tad,
For changing operating systems on servers is nobody's fad.
Metal, o! Metal, to see your Mettle,
Will the apk prevail, and to see txz derail?

Hi @Not_Oles ,

I would also love to try this.
Thank you.

Not_Oles · December 2022

Hi Guys!

So, in what I think was the default Alpine 3.17 edge install, I went to make an account for @tarasis. First I made a test account for myself.

fmt:~# adduser -h /home/notoles -s /bin/ash notoles
  [ . . . ]
fmt:~#

Wow, I was quite surprised when I logged in to my new notoles account and found that su(1) worked for my new account despite my not having added myself to the wheel group!

It seems:

/home/notoles # which su
/bin/su
/home/notoles # ls -l /bin/su
lrwxrwxrwx    1 root     root            11 Dec 11 05:07 /bin/su -> /bin/bbsuid
/home/notoles # ls -l /bin/bbsuid
---s--x--x    1 root     root         14160 Nov 19 10:13 /bin/bbsuid
/home/notoles #

Alpine seems to have a package called bbsuid, and the linked info page says "Obsolete package that can be removed." Nevertheless,

/home/notoles # apk del bbsuid
ERROR: No such package: bbsuid
/home/notoles #

So, as it stands, it looks like any new account can become root.

Might we have an Alpine freak who can explain to this Alpine noob the context of bbsuid? Maybe the "bb" means "busybox."

What should be done here? One hack might be to change the ownership of /bin/bbsid so that only wheel group members could run it. Or just delete /bin/bbsuid? What happens to /bin/bbsuid when/if sudo is installed?

@Not_Oles said: Clueless™

Aha!

New accounts paused already until I figure this out myself or somebody hits me with the clue bat. Thanks! Friendly greetings!

The thing about Darkstar is that, mysteriously, everything always seems to work. I remember awhile back when I was making several kinds of VMs on one of the AX line servers that I used to have. I just did Slackware as part of the test group. But then, everything worked out of the box on the test VM. So I put Slackware on Darkstar when I bought her. Since then everything seems to work including almost daily updates and compiling various kinds of stuff. So I do not expect to move Darkstar away from Slackware. Darkstar was not mentioned here because those accounts need to be advertised as LES Exclusive due to the pricing rules.

I imagined from the beginning that I might put NetBSD on the new Fremont server. But, as usual, I always want to try various options. Alpine seems especially fun because it seems really fast. From the way it runs in RAM, I think.

@vyas, you are Shakespeare reincarnate! Thank you for your poem!

I've never used Alpine Linux, so I'm speaking at a distance, but their "About" page says, "Alpine Linux is built around musl libc and busybox". (See https://alpinelinux.org/about/ .) Given this statement alone, I don't think that it would be a good idea to delete busybox or any part of it!

As a general analogy with BSD systems, one shouldn't mess with the base system

My perception of Alpine Linux -- again, at a distance -- has always been that it wouldn't be the best choice for a traditional multi-user system where everyone has a shell account (but perhaps I'm mistaken about this). In my view, Slackware would fit this purpose much better

Not good, of course

In this respect, it's odd that the page https://wiki.alpinelinux.org/wiki/Setting_up_a_new_user suggests that this doesn't (or shouldn't) happen

(Perhaps install doas and edit /etc/doas.d/doas.conf to deny the newly created user root access? But one shouldn't need to do this ...)

Hi! Could you please post or PM me your ed25519 ssh public key? Thanks!

Are ed25519 elliptic-curve SSH keys a technical requirement here, or just a preference to encourage good practice?

Many people prefer to use smartcards for SSH access, which adds an extra physical dimension of security, but are often limited to RSA or, if supporting elliptic-curve, not ed25519.

root · December 2022

This project reminds me of my first shell and first Linux learning machine. It was held by Nic-Nac-Project.de - now FreeShell.de - which offered free shells for postcards sent to the owner. I still have that account. These free shells are great ways to learn, test and spin stuff without the fear of breaking something as superuser.

This is a great project @Not_Oles and I hope many newbies will get onboard to learn Linux. Maybe (as a recommendation if I may) you could setup for users some remote desktop based on something light and modern (like LXQT) instead of SSH access. This way users may feel more comfortable nowadays when testing and learning BASH scripting. Back in the days of free shells the problem was computing power and bandwidth, which nowadays might not be the case (just an idea).

@Not_Oles is it OK really, as su isn't sudo ..? Just need strong root password.

Where is bbsuid used in Alpine Linux 3.17 edge default install?

This seems too many lines to post here on LES, but, if we look inside /bin, we see that almost all the /bin tools are symlinks to busybox. A few, however, maybe because they need SUID, are symlinked to bbsuid.

fmt:~#

From lists.alpinelinux.org

the suid binaries are only:
"/bin/mount",
"/bin/ping",
"/bin/ping6",
"/bin/umount",
"/usr/bin/crontab",
"/usr/bin/passwd",
"/usr/bin/su",
"/usr/bin/traceroute",

So, grep for bbsuid inside /usr/bin

fmt:~# ls -l /usr/bin | grep bbsuid
lrwxrwxrwx    1 root     root            11 Dec 12 17:33 crontab -> /bin/bbsuid

lrwxrwxrwx    1 root     root            11 Dec 12 17:33 traceroute -> /bin/bbsuid
lrwxrwxrwx    1 root     root            11 Dec 12 17:33 traceroute6 -> /bin/bbsuid
lrwxrwxrwx    1 root     root            11 Dec 12 17:33 vlock -> /bin/bbsuid

I love Alpine,I have two machine with Alpine,It's small and powerful.
Just a little bit: it can't be switch to google bbr,I am confused.

Hi @brick2008!

I looked at https://github.com/google/bbr, the README.md says

"This open source distribution contains documentation, scripts, and
other materials related to the BBR congestion control algorithm."

Can you please add some more details about why Alpine can't be swtched to BBR?

Friendly greetings!

Where is bbsuid used in Alpine Linux 3.17 edge default install?

Inside /bin

grep for bbsuid

From lists.alpinelinux.org

So, grep for bbsuid inside /usr/bin
