Troubleshooting FTP Client Connections

Use this topic to troubleshoot problems making connections using the FTP Client.

Configuring Connections

  • Did you enter your server name, user name, and password correctly? If you are connecting to a case-sensitive server, be sure to use the correct case when making these entries.
  • Does your site use a passthrough server or SOCKS proxy server to ensure that only authorized users have access to server sites? If so, you should configure the client to connect via the firewall or SOCKS proxy server.
  • When opening a connection, the server name you provide is resolved via the HOSTS file or a domain name server. If you have no domain name server on the local network and don't use a HOSTS file, you must specify the full IP address of the host server. For example: 124.24.36.85
  • If the FTP server is not running on the remote system, you can't connect.
  • Server response time can be affected by the distance between sites. If you see the message "Connection timed out" when trying to connect to a server, increase the value of Timeouts in seconds on the Connection tab of the Site Properties dialog box.
  • If the FTP Client is unable to determine the server type, server directory listings may display incorrectly. You can use the Directory Definition Wizard to modify the directory format.
  • If you are having trouble making a Secure Shell connection, use the Secure Shell log to get troubleshooting information.
