## Solution Steps
* SSH into the virtual machine and type `ip addr` to list the network interfaces, with 192.168.25.2/28 being the host's private IP address. This means that each host on the subnet will be 192.168.25.x/28, and to search the entire network it would be 192.168.25.0/28.
* Perform an Nmap host discovery scan using a few different commands:
* `nmap -sn 192.168.25.0/28`
* `nmap -sL 192.168.25.0/28`
* `nmap -Pn 192.168.25.0/28`
* With the other active host being 192.168.25.3 with a few open ports, perform a version scan with `nmap -sV 192.168.25.3`
* Flag: `jctf{2-4}` or `jctf{2-4 (RPC #100000)}` or `jctf{rpcbind 2-4 (RPC #100000)}` or `jctf{rpcbind 2-4}`
