If you encounter any problems when using FTP Client or Server, the easiest way to resolve any problems is to review the contents of the FTP message logs.

The message logs list all commands sent and received during your FTP session. If you are using the Client and Server together, you can see the sequence of commands and replies in both message logs. Otherwise, you can only see your end of the transaction.

By examining these logs, you might spot the reason for the problems you encounter.

General Troubleshooting Tips for FTP Client

If the information in the FTP Client message log does not help you, check the following items:

1. If you can send and receive files, but the files are corrupted after transmission, verify you are using the correct file transfer mode. Use ASCII mode for text files, Binary mode for executable files, compressed files, graphics files, and other non-text files, and Local 8 mode if the remote host is a system that does not use the standard 8-bit byte.
2. Make sure the FTP server is running.
3. Ping the FTP server to make sure the server is available.
4. Make sure that the host to which you are trying to connect is not running behind an IP packet-filtering firewall. If it is, check the Passive Mode check box in the Advanced options in the Connect dialog box. If your network uses another kind of firewall, fill in the firewall proxy attributes in the Advanced options.
5. If you chose Auto Detect in the Host System Type drop-down list in the Connect dialog box, view the contents of the message log to discover the correct system information. Then, either choose the correct system type from the Host System Type drop-down list or choose Unknown.
6. Make sure you have entered the correct user name and password.
7. Make sure you are attempting to work in only authorized directories and that you have adequate privileges for the work you are attempting to do. If you cannot access the directories and files you need, contact the FTP server administrator.

If the information in the FTP Server log does not help you, check the following items:

1. Make sure the FTP Server is running by viewing the contents of the FTP Server window. You should see the words "Server started."
2. Make sure your workstation is properly connected to the network and that the network is running.
3. Make sure the system on which the FTP client is running is properly connected to the network and that the network is running.
4. Make sure you have entered the correct user name and password for the user.
5. Make sure the user is entering the correct user name and password.
6. Make sure the user is working in the authorized directories and has adequate privileges for the work the user is attempting to do.
