| How to test FTP command without a communication line in IBM i(AS400)? |
When there is no communication line exists or accessible to us and we want to test the FTP commands on the local IBM i machine then there is a way to test the FTP commands. Therefore, In this article i will put some light on the same for you to get some insight.
Let's discuss the approach to test the FTP commands without any communication line/remote machine in IBM i.
FTP loopback
Try to use loopback instead of domain name/ip address this will start a session where the remote machine is actually the local IBM i(AS400) machine.
MAIN IBM i Main Menu
System: PUB400
Select one of the following:
1. User tasks
2. Office tasks

4. Files, libraries, and folders
5. Programming

9. Display a menu
10. Information Assistant options
11. IBM i Access tasks
90. Sign off
Selection or command
===> ftp loopback

Previous FTP subcommands and messages:
Connecting to host LOOPBACK at address 127.0.0.1 using port 21.
220-QTCP at LOOPBACK.
220 Connection will close if idle more than 1666 minutes.
Enter login ID (easyclass):
