Some questions about ssh and Overthewire:wargames (lemmy.ml)

Hi there, In my search to learn a bit more about Linux, i came across this website called "OverTheWire", which teaches basic and some advanced concepts over SSH. It seems like a fun and engaging way to learn.

However, as a bit of a paranoid beginner when it comes to Linux and networking, i find myself worrying about the potential dangers of connecting to an untrusted network.

So, my questions are:

  1. Does anyone have any experience with the website?

  2. In the hypothetical case that I open an SSH connection to a compromised network, could that expose me to attacks? (Aside from obvious risks like downloading malicious files myself.)

  3. Should I use a virtual machine (VM) for this?

I sincerely appreciate any responses. Thank you!

Hi. You could run your ssh-client on a virtual machine or find another solution to sandbox your client (e.g. firejail if you are on linux). Just for ssh, a very lightweight vm would cut it.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
