Many broken machines in Starting Point?

Off-topic

Hello,

I’m new here, so maybe just a noob problem, but I am currently doing the Starting Point machines and am facing now the 3rd one which is simply not working for me.

  • :white_check_mark: Responder: Couldn’t connect via evil-winrm (seems to be a common issue)
  • :white_check_mark: Bike: The injection simply didn’t work, always received a timeout instead of the expected response
  • :white_check_mark: Funnel: Can’t ssh into the machine:

I am using an up-to-date Kali Linux VM, I am connected to OpenVPN, I tried resetting the boxes, nothing helped. What am I doing wrong? Is this a common issue?

Edit: At least I could ssh now after reducing the MTU size. Maybe that helps also for the other issues, we’ll see.
Edit2: Reducing MTU also helped for Bike.
Edit3: Crazy, also evil-winrm is working now. They should really mention that MTU in a FAQ.

Thanks,
Snafu
