Fetch: Secure File Transfer Protocol for Macintosh OS X
program for transferring files, similar to WinSCP for Windows. It
uses the Secure File Transfer Protocol (SFTP) to allow a networked Mac to
transfer files directly from or to any connected machine that
supports SFTP. Click here
if Fetch is not installed on your computer. NOTE: this link requires that you be on the Wellesley Secure wifi network or, if off campus, on the VPN.
Connecting to a server with Fetch
Each academic or administrative department has been assigned
a User ID and password by the Wellesley webmaster to transfer files to
the Wellesley web server. Contact your department's content provider or
the college Webmaster for
the User ID and password. Please note: student workers are not allowed
to access accounts on www.wellesley.edu.
CS students who need to transfer files to cs.wellesley.edu
should have received a User ID and password from their instructors.

after launching, click and hold on the icon in the dock, then in the
menu that appears, choose Keep in Dock.)
- In the Hostname field, type www.wellesley.edu to

you'd like them to appear in. You may need to click the Refresh button
in the account window to see the newly uploaded file(s) or folder.
Note: If you want to put up information
which should only be accessible on campus, please contact the Webmaster.
Downloading files to your computer
When you download a file, you place a copy of a file on the server
onto your computer. To download a file using Fetch:
- Navigate to the desired file(s) or folder on the server in the account
window. Double-click folders to open them. To go up a folder level,

Creating a new directory (folder)
Use the New Folder button, or ctrl-click
in the account window and select New Folder.
Deleting files and folders
Before you delete uploaded files, be certain that you have a
backup. It is impossible to replace files once you have deleted them. Please
be certain you are deleting what you intend to delete.
Find the file or folder you wish to delete and use the Delete
button,or ctrl-click on the file(s) or folder and choose Delete Item.
Naming web pages and managing web
While directories/folders should always have an initial capital
(e.g., Images or RelOrgs), individual files should always be in all lowercase
letters. File names should contain only letters and numbers, and no spaces.
File names should also be short (up to 10 characters, not counting the .html extension).
The Wellesley Standard requires that all pages end with .html.
Other pages on the Internet occasionally end with .htm, but Wellesley
requires the full .html so that all pages on the college web site
are standardized, and so that our search engine knows which files to index.
Before you create your pages, decide on a naming structure.
File names should be unique, but should also make sense to you and indicate
the purpose of the file.
Don't change web page file names. If you do, all links to
that page will be broken. You should not rename files without a good reason,
since the repair and crosschecking required afterwards is often tedious,
and can cause difficulties for other people attempting to access your site.
If you must rename your site's homepage (this is strongly discouraged),
notify your department's content provider and the college Webmaster so
that links to your home page can be changed.
We recommend that you keep a complete backup copy of your web
site on your computer or a CD or zip disk. When you want to edit your web
page, make the change on your backup copy, then upload the changed files
server. You may also want to keep archival copies of your web pages labeled
with the date. Invest the
time in creating a system that works for you;
unorganized files are confusing, and may cause references to images and
links to break.
To quit Fetch, Go to the Fetch menu and select Quit
Fetch. This will disconnect you from the account and quit the program.
- Fetch will not connect to the SFTP host
If Fetch displays a message similar to "Warning: the RSA host key for 'ftp.example.com' differs from the key for the IP address '184.108.40.206'" when opening a connection to an SFTP server, it may indicate that the host's ssh key has changed. In order to re-establish your connection to the host follow these steps:
- Quit Fetch.
- In the Finder, choose Go > Go to Folder. The Finder will display a prompt.
- Type "~/.ssh" (without the quotes) into the prompt, and click the Go button. The Finder will display a window showing the contents of the .ssh folder.
- Select the known_hosts file, and drag it to the Trash.
- Close the window and re-launch Fetch.
After deleting the known_hosts file, the first time you connect to a server you may be warned that the authenticity of the host cannot be established. This is normal - click the "Accept..." or "OK..." button to proceed.
