Transferring files across networks

Using Netscape to download files

While browsing the Web, you may find that you would like to have copies of some of the files you find. These may be images, sounds, text files or just about anything. Most web pages can be saved by selecting "Save As" from the File menu. For other files, things work differently. Often, you will need to right-click on the link or image and choose "Save Image As" or "Save Link As", in order to save it.

Follow this link to see where it goes, then press the "Back" button to return.

Now, instead of clicking the link with the left button and following it, click on it with the right button. You should see a small menu.

Choose "Save Link As" and save it to the Desktop.

Now you've saved this file to the Desktop just like you saved your Notepad file. You can even open it in Notepad to see what it looks like.

Transferring a file with Netscape FTP

Now that you've downloaded the file from our computer to yours, you will upload it from your computer to your Unix account using Netscape's FTP. FTP stands for File Transfer Protocol and is one of the most common ways of transferring files over the internet. Because every operating system is different and has its own way of storing files, the computer community developed this language out of necessity to communicate and send files between different systems.

1. In your Netscape Window, choose "File | New | Navigator Window". This will give you another Netscape window, so that you can still read this one.
2. In the new window, choose "File | Open Page"
3. Type in ftp://username@arizona.princeton.edu/u/username (remember to type your own username wherever it says "username"), and then click "Open"
4. Type in your password when prompted and then click "OK"

It may take a moment, but now you should see a list of files (with white page icons) and directories (with yellow folder icons). Find the directory you created earlier, called "COS111", and click on it. This should bring you into that directory.

1. Choose "File | Upload File".
2. Find the file you saved on to the Desktop and then click on "Open"

Your file should have uploaded successfully and should appear in the list in your Netscape Window.

Verifying the transfer

Here is a chance for you to use your newfound Unix skill to see if the file uploaded correctly. In your Telnet window, you should still be running the mail program pine. Check your email to see if you received the messages from the last section of this lab, then exit pine by pressing "Q". Now you should see a Unix command prompt again.

1. Type "cd home" to bring you back to your home directory
2. Move to your cos111 directory by typing "cd cos111"
3. Check the contents of that directory by typing "ls"

You should see the file you just uploaded in this directory if you uploaded it correctly. If you are having problems, ask a TA for assistance.
