File Transfer with Fetch
In order to transfer files between your computer and a UNIX system such as ACS or a web server, you’ll need to use an FTP (file transfer protocol) client. Fetch is a simple Mac program that lets you easily use FTP to move files back and forth between your Mac and that remote UNIX system. Because Boston University has a site license for Fetch, current BU students, staff, and faculty may use it for free.
Download and Install Fetch
- Download the software from theÂ Fetch homepage.
- When you have completed the download and have run the installer, launch the application.
- When Fetch launches, if you have not previously licensed a copy on this computer, you will see buttons that offer different ways to register.*
- Choose Enter Serial Number. You will be prompted to enter a name and a serial number:
- For the name, you must enterÂ Boston University.
- For Fetch 5.x: enterÂ FETCHED001-7FEK-WL2D-LF36-00L5-BN07 as the serial number.
- For Fetch 4.x: enterÂ FETCHEX001-J9AA-D5BH-339M-GHPS-9EPQ as the serial number.
* If Fetch launches without ever prompting you to register, this just means that you already have a licensed version on your computer (this will happen if you upgrade your computer from a licensed version 4 to version 5, for example).
There are two different types of FTP sites:
- Public or “Anonymous” FTP sites are open to anyone who wishes to retrieve information from them. Usually, you cannot upload to public FTP sites, but you can download any of the information they provide for use on your own computer.
- Password-protected FTP sites are directories on a server from which you can upload and download files. Typically, at BU, you might upload and download from your own ACS account (acs.bu.edu) with an FTP program. You might also need an FTP program to upload files to your personal website at people.bu.edu. FTP programs can also be used to delete or rename files, or create folders (directories) on these servers.
To use Fetch, you must be connected to a wired or wireless Internet connection.
The first time you use Fetch
In some versions of Mac OS X, Fetch will have trouble displaying the list of files on the UNIX server. To avoid this problem, open Fetch then go to Fetch -> Preferences, click on the Firewall tab, and put a checkmark next to Use passive mode transfers (PASV). Fetch will remember this setting the next time you use it, so you only should need to do it once.
Access a Public FTP Site
- When you open Fetch, choose File-New Connection to open the window that you use to connect to an FTP site.
- Using BU’s FTP site as an example, set up the connection window to go to the Host ftp.bu.edu. Sometimes, the password is your full email address and the User ID is “ftp” or “anonymous”. More likely, though, you can just leave all remaining fields blank.
- Once you click on OK, you will see directories in the FTP site listed.
- To open a directory, double-click on it. When you find the file you need, drag its icon to your desktop and it will download.
Access Your Own (Password-protected) Sites
The steps for accessing password-protected sites are similar, except that you need to use your own BU login name and Kerberos password.
For Your ACS Account
When you open Fetch, choose File-New Connection to open the window that you use to connect to an FTP site.
The Host address is acs.bu.edu, the User ID is your BU login and Password is your Kerberos password.
Below we are using a sample User ID “jschmoe” — but you would use your own information.
For Your Account on the Public Web Server (You must first sign up for an account at people.bu.edu.)
Manage Directories and Files
Upload and Download
- To open a directory, double-click on it. When you find the file you need, just drag its icon to your desktop and it will download.
- To upload a file, drag it from its location on your Mac right onto the Fetch window. After the upload finishes, you should then see that file with the list of other files on the server
Modify Files and Directories
- To Rename or Delete a file or directory simply select it (by clicking on it once) and use the Remote menu command to access either of these options.
- Use the Directories menu command to create a new directory on the server.
Information about connecting to a BU departmental or people.bu.edu site can be found in the Websites section of TechWeb.
