Name three steps you'd take to troubleshoot a problem with an FTP server.

Answer»

The THREE steps you'd take to troubleshoot a problem with an FTP server are:

  • Ping can be used to test basic connectivity.  The "ping" command uses a "echo request," which is an ICMP component (Internet Control Message Protocol). When you ping a DEVICE, you're making an echo request, and if the device is active or online, you'll get an echo back.
  • Use Nmap to see if the ports are open (20 and 21). The Nmap HOSTED security tool can ASSIST you in determining the effectiveness of your firewall and security settings. Ports are numbered addresses for network communication on current operating systems. By default, different types of services use distinct ports. Because port configuration might pose a security risk, knowing which ports are open and which are blocked is crucial. 
  • Check to see if the server's TRAFFIC is being restricted by a firewall.
