De-ICE S1.100 on Vagrant-libvirt

Sets up a libvirt virtual network to enable access to de-ice s1.100 which runs on 192.168.1.100/24.

Using it

• Download the "De-ICE_S1.100.iso" file into this directory, leaving it named exactly that.

  When I last tried, it wasn't working to download it from the url linked from vulnhub, so I got a copy from Internet Archive's Wayback Machine and uploaded it to my dropbox account.

  • Wayback Archives link: https://web.archive.org/web/20190831103512/https://hackingdojo.com/downloads/iso/De-ICE_S1.100.iso
  • My dropbox share: https://www.dropbox.com/s/v6vuy9b86nqr881/De-ICE_S1.100.iso?dl=1

• Grant global execute privileges to the iso so that user qemu can find the iso:

  sudo chmod a+x De-ICE_S1.100.iso
  

• Then, run vagrant up.

All together:

$ git clone https://github.com/deargle/lab-de-ice-s1-100 && cd lab-de-ice-s1-100
$ wget https://www.dropbox.com/s/v6vuy9b86nqr881/De-ICE_S1.100.iso?dl=1 -O De-ICE_S1.100.iso
$ chmod a+x De-ICE_S1.100.iso
$ sudo vagrant up

Enabling legacy ssh KEX

The ssh key exchange algo (kex) that the vm uses is obsolete. You may need to edit your ssh client to permit its use.

For example, if you get the following error message when you try to ssh:

└─$ ssh 192.168.1.100                                                                  
Unable to negotiate with 192.168.1.100 port 22: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

Then you could pass the following option in each ssh call:

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 192.168.1.100

Or you could add the following to your ~/.ssh/config file:

Host 192.168.1.100
    KexAlgorithms +diffie-hellman-group1-sha1
