+Hi everyone, we've opened a pentestlab that hosts a Metasploitable 2 (http://r-7.co/Metasploitable2) image and a Kali (https://www.kali.org/) image.
+If you want to explore the network just connect with ssh to pentester@pentest-gw.intern.fslab.de (requiers VPN to HBRS), right after writing me to add you ssh key there.
+Happy hacking!
