I need a Linux developer

This two-virtual machine environment is designed to be a general-purpose network penetration testing, attack/defense training environment. It consists of a Kali Linux pen-testing VM (kali.example.com) as well as a vulnerable target system running Windows 7(64bit) VM (target.example.com) residing on a dedicated /20 "network bubble" in the cloud. It features proxied web access for allowing indirect web file downloads, webmail, and even Google drive or student LMS use, but cannot directly send any packets outside its own network bubble, i.e., no external ping/ICMP, traceroute, or even external DNS server queries can be used to get "out of the Range." The environment can be used safely with many of the Range's predefined pen-testing labs, as well as free form network scanning, DoS/pen-testing, red team/blue team capture the flags, client/server sniffing, and general attack/defense classes or testing. NOTE: The version of Windows in this environment is older and more vulnerable by design, and should not be used for teaching current Windows systems IT training or OS patching best practices; more modern Windows 10 VMs should be used in that case. The login username/password on each VM is student/student. For root or admin access, use "sudo su -" on Kali, and "Run As Administrator" on Windows.
