Part 3: Printer

These ports are accessible on the printer fiddle.cs.colostate.edu:

        21/tcp   open  ftp
        23/tcp   open  telnet
        80/tcp   open  http
        443/tcp  open  https
        515/tcp  open  printer
        631/tcp  open  ipp
        7627/tcp open  soap-http
        9100/tcp open  jetdirect

Look for a computer in the entire 23-bit CS subnet that has the “domain” port open. There should be only one.
