[Problem solving]

1. I accessed the server with rcity7 user.

 

 

2. There was no "flag" file. So I had to find a running network port as shown in the problem information.

 

 

3. I used the "netstat -a" command to check the network connection status, but the "netstat" command doesn't work. Therefore, I scanned the localhost using "nmap", a tool for scanning the network. Of the open ports, port 9999 was suspected.

 

 

4. I used "netcat" to access that port, and putted the password.

You could find more description or options about nmap, netcat using "man" command.
