UCAR FTP server

Uploading files | Downloading files

Authorized UCAR persons and NCAR personnel (individuals who have valid NCAR scientist and project numbers) can use the UCAR FTP server to share files with anyone who needs to download them if no secure method is available.

This server should not be used for data storage.

To request an ftp.ucar.edu account, contact CISL IT Support.

Uploading files

Log in to ftp.ucar.edu with your FTP client (see image) or by entering the following on your command line.

ftp ftp.ucar.edu

You will be in your own personal directory (/pub/cisl/username, for example) and can upload files only to that directory or subdirectories that you create. Execute the usual FTP commands* to put the files in your login directory or a subdirectory.

When using FTP client software such as WinSCP or FileZilla, be sure to select FTP and specify Port 21 rather than SFTP and Port 22 to log in to ftp.ucar.edu.

Notify the intended recipient of the full path name to make the files easy to locate.

Ask the recipient to download the files. Remove them from the server once the recipient has downloaded them.

Keep in mind that anyone can access files kept on the server in a public folder.

Do not store sensitive or critical data there.

Downloading files

You do not need an account to download public files from the FTP server.

Use one of the following methods if you do not have an account.
