Artist idea for the release artwork (lemmy.sdf.org)
submitted 10 months ago by [email protected] to c/[email protected]
0 comments fedilink

As the next release is slowly cooking, I'd like to mention an artist that I love: @pmjv, or prahou. He's been dedicated to submitting awesome artwork about his universe, here at /c/unix_surrealism, which features many openbsd related comics (puffy being an important protagonist).

I was thus wondering how an artist could pretend at submitting an artwork for the next release ? Is it a shortlist ? Do you simply upload some on the mail list ?

endlessh-go: a Golang SSH tarpit that traps bots/scanners by wgs in c/[email protected]
[-] [email protected] 25 points 1 year ago

endlessh was pretty cool and a more modern version is even better ! I'll give it a shot !

On a side note, I found a way to trap HTTP connections too while working on my cyb.farm project. The go implementation is ridiculously simple: tarpit.go. It works by providing an endless stream of custom headers to the client, which it is supposed to ingest before getting to the content itself.

Presoldered split keyboard (lemmy.sdf.org)

Hi everyone! I'm planning on getting a split keyboard to replace my planck, but I don't have a soldering iron.

What are my options ? Ideally I want:

  • DIY, no soldering involved
  • QMK firmware
  • 40% format

The keyboard I'm leaning toward is the let's split as it's a planck split in two halves, but it seems that you need to at least solder the keycaps yourself, which I can't.

I tried but got an error:

Is it expected ? Did I type something wrong ? I'm confused...

Chapter 0x02 - Is it too abstract ? (lemmy.sdf.org)
submitted 2 years ago by [email protected] to c/[email protected]
0 comments fedilink

Hey everyone !

With so many people stuck at 200 points on the board, I'm wondering if the chapter 2 isn't too "abstract" ?

The Cyb3r Hunt is meant to be challenging, but it shouldn't discourage players because they can't figure out what to do.

For those that went past it, did you find the solution sketchy ? Did it all make sense, or you went past it without really understanding what all these files were for ?

For those stuck, where are you stuck at (please use a spoiler tag) ?

I'm considering removing some files I consider "optional", and changing the hint to make it less like a guessing game as to what to do.

Any opinions on this ?

Cyber hunt - A technical adventure for Unix fans! (cyb.farm)
submitted 2 years ago by [email protected] to c/[email protected]
7 comments fedilink

I've been working on this project for over a year now, and I'm sure many people here will like it !

This is a game where the player must complete technical challenges about various technologies (programming, cryptography, networking, etc...) to progress through the story. It puts the Unix family under the light, and features many opensource technologies all running on a single server!

Check out the about page for details, and happy hunting !

Cyber hunt - An epochalyptic adventure ! (cyb.farm)
submitted 2 years ago by [email protected] to c/[email protected]

Over the past year, I've created technical adventure for people eager to challenge their skill and knowledge about many technical fields, while also having fun !

Programming, version control, command line, network protocols, cryptography, steganography, games, … Thorough the game you'll switch from decades old to state of the art technologies, and use it all to progress through a dystopian story happening around the 2^nd^ Epochalypse.

Get your systems ready, and hope that you'll be done with it before the Advent of Code starts, because you will probably not handle both at the same time ;)

cross-posted from: https://lemmy.sdf.org/post/5947610

On the 19th of January [...] The admin team was helpless. In the split of a second, the whole CYBFARM network went down. Every subsystem on the planet stopped, and there was nothing they could do against it. The CYBFARM has always been autonomous, and nobody had enough knowledges of its internals to debug or fix anything.

Hopefully, a few minutes later, the first system came back up: the security module. Then other subsystems rebooted one after the others, and the production of goods restarted as expected.

We later found that an overflow occurred in the system clock. This caused a disruption of the internal message bus of the CYBFARM, which entered a locked state, and shut itself down to prevent harming the subsystems. The CYBFARM eventually found and patched the bug automatically, without any external intervention from our part. This was the first time in History that [an autonomous system] healed itself without human action!

This is such a major milestone in History!

Tabs are objectively better than spaces - gomakethings.com by wgs in c/[email protected]

Tabs for indent, spaces for alignment. This is the way, I can't believe people are still fighting that ?

[-] [email protected] 44 points 2 years ago

Because other people might have restricted environment which might not suit their preference is not a good reason to level it down IMO.

Also, I think 9 is the best size for indent (matter of preference), do you think I should switch to space so everyone can enjoy this wonderful view I have ?

Today GNU/Linux is 32 years old by wgs in c/[email protected]
[-] [email protected] 56 points 2 years ago

Weight your words my friend! GNU's a behemoth !

GCC alone is almost as big as Linux. Add core/binutils, the Hurd, ... And you easily outclass the kernel itself !

~ $ du -sh linux-6.4.12/ gcc-13.2.0/                    1.5G    linux-6.4.12/                                   1.1G    gcc-13.2.0/

Oh, and Emacs.

What's the best way to prevent IPv6 from leaking when using Wireguard? by wgs in c/[email protected]
[-] [email protected] 27 points 2 years ago* (last edited 2 years ago)

IPv4 and IPv6 are two different network stacks. Your IPv4 stack is hidden behind wireguard, but not the IPv6 one.

The correct way to fix your issue is to setup a second witeguard tunnel for IPv6, and route IPv6 traffic through it.

Edit: many comments advise to block outbound IPv6 traffic. Don't do that! It will add latency to all your requests as you will have to wait for them to timeout.

[RANT] I pay $70/mo for this privilege by wgs in c/[email protected]
[-] [email protected] 23 points 2 years ago* (last edited 2 years ago)

I'm reading all the comments and I'm shocked... In France, with uncapped access and 1Gbps down/600Mbps up (theorical) I pay 40€/mo (30€ every six month when I call to complain that it's too expensive). And it's definitely not the cheapest provider.

That's insane !

Another good reason not to open port 22 by wgs in c/[email protected]
[-] [email protected] 24 points 2 years ago

I get what you say, and you're definitely not wrong to do it. But as I see it, you only saved ~80Kib of ingress and a few lines of logs in the end. From my monitoring I get ~5000 failed auth per day, which account for less than 1Mbps average bandwidth for the day.

It's not like it's consuming my 1Gbps bandwidth or threatening me as I enforce ssh key login. I like to keep things simple, and ssh on port 22 over internet makes it easy to access my boxes from anywhere.

My first E-Mail server by wgs in c/[email protected]
[-] [email protected] 25 points 2 years ago* (last edited 2 years ago)

Congratulations! A mail server is quite demanding in terms of initial setup, but it's also very rewarding !

Here are a few pointers I can give you:

  • Using a good domain is important, some provider block entire TLDs for cheap domains (eg. .tk or .pw). I learnt it the hard way...
  • Set your MX records to A records, not CNAME
  • Ensure your PTR records match your A records for the mail server
  • Learn about SPF and DKIM
  • Set them up, and verify with mxtoolbox
  • Use the ip4: and/or ip6: selectors for SPF
  • Setup a spamfilter (I like spamassassin)
  • Leave it all running for a few weeks/months
  • Publish a DMARC policy on your DNS, and verify with mxtoolbox

This should limit a lot your likeliness to end up in spam folders (which is usually the hardest part about running your mail server)

Tor’s shadowy reputation will only end if we all use it | Engadget by wgs in c/[email protected]
[-] [email protected] 28 points 2 years ago

You don't need to access a .onion instance to use Tor. You can simply perform your day-to-day web usage through Tor directly.

On your phone, you can even use Tor natively with most of your apps.

[ELI5] What is a reverse proxy exactly and how do I use it to run several dockerized services on one machine? by wgs in c/[email protected]
[-] [email protected] 59 points 2 years ago

ELI5

So it's saturday afternoon, a very hot one, so you ask your daddy for an ice cream (hosted service). The shop you go in is very bizarre though, as there is one vendor (TCP port) for each flavor (docker service/virtualhost). But it's tricky because they're all roaming in the shop, and you don't know who's responsible for each flavor. Your dad is also not very comfortable paying these vendors directly because they only accept cash and do not provide any receipt (self-signed certificate/no TLS).

Hopefully, there is the manager (reverseproxy) ! This girl is right where you expect her: behind the counter (port 80/443), accept credit cards and has a receipt machine (Domain name + associated certificate). She also knows everyone on her team, and who's responsible for each flavor !

So you and your dad come to see the nice lady, ask for a strawberry + chocolate ice cream, and pay her directly. Once done, she forwards your request directly to the vendors responsible for each flavor, and give you back your ice cream + receipt. Life is good, and tasty !
