I throw CTFs for a living (among other things), and I’m happy to help out a fellow Infosec person.
What kind of infrastructure can you deploy? Is this going to be in the cloud, on-prem (via a hypervisor like Proxmox/vSphere, or hosted on a single laptop/server?
We have a proxmox cluster, which is where this would probably go, but I would prefer a non-integrated solution, rather a single thing I can either put within a proxmox vm (nested virtualization) or on an on premise piece of physical hardware.
So first, let me be clear - I don’t know if an alternative to that software you first brought up. But some of our earlier CTFs had a similar issue with isolation.
We ended up spinning up new VLANs per contestant, each having a single Kali Linux VM with xrdp, along with each contestants target systems. Our router/fw blocked all access in/out of those VLANs, save for RDP/SSH traffic from our Apache Guacamole server on the DMZ.
So contestants would hit our portal (Guacamole), then from there connect into their own dedicated Kali instance and environment.
Later, we had to make additional fw exemptions for our scoreboard/docs, etc.
Thanks for sharing your work at Lemmy! I say this because although I don’t use Reddit, I’m sure that logically because there are more users there and being more famous, it is the preferred platform for developers to share their work.
Think you’ll implement a replay feature in the future? I love that feature.
And is there any chance of porting your job in the future to Wayland? Currently there is no program (only OBS, as far as I know) that allows recording in Wayland, it would be great to have more options.
I haven’t made the jump to Wayland yet. I basically live in the terminal (when I’m not playing games!) so haven’t been in any rush. I definitely want to support Wayland going forward because it seems everyone has switched but me!
His coding videos are really nice to see. I don’t even understand that much, as it’s mostly C++, but the coding, the explanation, and the final feature and commit is somehow relaxing.
(I promise you this statement is related. It’s a little bit of history on BTRFS/ReiserFS though. BTRFS actually has support for in-place conversion from EXT and… ReiserFS, as it was kind of a competitor and the same engineers worked in ReiserFS)
Timeshift forces you to use a very specific layout of btrfs partitions or whatever those are called. On Fedora.for instance, unless you set them up manually, Timeshift will not work. Snapper isn’t so picky.
I never had to set it up. I use endeavour OS and all I did was choose “btrfs” in the installer. That’s it. I just installed timeshift after that and ran it like normal. No issues. Installed auto snap and grub-btrfs and I’m in the races.
