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.
Whatever is default on the distro I run.
If I see squares with numbers in them somewhere, I install the biggest font metapackage I can find in the repo, which usually fixes it.
Still not correct. The path is perfectly correct. Even using full path. This method EXPECTS a repo package, not a file. I already figured the answer, it’s in this thread.
I think you have confused the apt command with the apt-get command. apt-get doesn’t handle files, while apt has it since the very first version. This is one of the important differences between the two commands. This was one of the main reasons why I have been using only apt for years.
Again, incorrect. The answer is above. And still, you haven’t read the thread. This is NOT about getting rescuezilla to install in the current PC. This is to get it to install in a DIFFERENT PC, which happens to be OFFLINE. So apt by itself will FAIL when it tries to resolve dependencies.
I don’t but i note increasing difficulty in upgrading/keeping prior extensions to the new version of gnome.
For example, “recent files” extensions for the top bar used to number in the threes I think. With the last gnome version there was only one which wasn’t the most useful of the lot. I use it because it makes it easier beginning again the following day, rather than the extra step of opening the file mangler. I’ll probably go with the majority and drop it once I upgrade to Fedora 39.
Looks like gnome is becoming more useful to people in basic guise, incorporating many of the extension functions within the main GUI, and so the once popular extensions are becoming unmaintained.
Installing Microsoft TTF packages on my distro used to be one of the first things I did. Sometime back I ended up finding suitable replacements that are stock (less packages, less installation steps, less proprietary software.)
I’ve recently found the Inter-font package (mentioned in one of Infinitely Galactic’s YouTube videos. It’s excellent, clean like Noto Sans, but slightly more readable. I’ll swap in the Ubuntu font every now and then for fun though, I really like that one too.
