Free IPv6-only KVM VPS for 1 month

skhron

Hello, LES!

I would like to giveaway twenty(!) IPv6-only KVM VPS for 1 month. To get them you need to:

1. study what SQL injection vulnerabilities are and how to use exploit them >:)
2. go to the Damn vulnerable website and try to hack that authentication form to obtain promocode
3. order Nano-1 VPS, do not add IPv4 and apply the promocode.
4. PROFIT!

Please do not:

1. disclose the promocode to anyone,
2. register multiple accounts at our billing - be nice and use this promo once per person.

Hope you will learn something new and enjoy this Nano-CTF

Just signed up for the fun of it (got the promocode with my first attempt).

Let's do a mini review:

The VPS comes with a /64 on-link IPv6, CPU is "Intel(R) Xeon(R) Silver 4114" (which shows up as "Intel Xeon Processor (Skylake, IBRS)", "cpu MHz: 2199.998" and "bogomips: 4399.99" in /proc/cpuinfo).

Only "Alpine Linux v3.15" is provided as an installation option. You can also boot into netboot.xyz, but that doesn't seem to get over network configuration (maybe because it expects to be able to get an IPv4 address)

free tells me

              total        used        free      shared  buff/cache   available
Mem:         459976       67672      329000         296       63304      379652
Swap:             0           0           0

Thanks for reporting this, I will check what can I do and how to fix that.

@yoursunny, we provide routable /64 IPv6 as well

Who's lying?

these statements don't contradict each other

skhron

@yoursunny said: Who's lying?

Actually, there was a bug with network configuration. Now it is certainly routable

@cmeerw said: these statements don't contradict each other

Previously /64 routes were without nexthop:

2a09:b280:fe00:b::/64 dev 7281317570 metric 1024 pref medium

And now I have fixed it:

2a09:b280:fe00:d::a dev 8068423991 metric 1024 pref medium
2a09:b280:fe00:d::/64 via 2a09:b280:fe00:d::a dev 8068423991 metric 1024 pref medium

I would like to use it for studying Wrangler.

There are only 8 out of 20 activations of the promocode, you still have plenty of time to play later

sh97

Nice exercise!
Managed to grab one, thank you!

terrorgen

@Not_Oles probably a better idea for MetalVPS?

JBB

Well, that was fun. Thanks!

No free chicken for you! Come back ten year!!!!

That was fun! I don't need more servers, but that was a very interesting way to introduce a promo

somik

Can confirm that it is working. But do not need a another server.

Hey @skhron just curious, do you offer BGP sessions on the regular plans?

Currently we just cannot provide BGP, however we have plans to provide it. We will make an announcement when this happens

skhron

By the way, I can see that 20 out of 20 servers were given away. Thanks you all for your interest

Ganonk

thankyou
