Setting Up FTP Server
FTP (File Transfer Protocol) - An Internet protocol that allows users to transfer files from and to remote computers.
If you have IIS (Internet Information Services) installed on your computer, you can set up your computer as a FTP server. Here is how:
1. Run Control Panel / Administrative Tools / Internet Information Services.
2. Expand the "local computer" entry and the "FTP Sites" folder, you will see the "Default FTP Site" service.
3. Right mouse click on the "Default FTP Site", and select Properties. The properties dialog box shows up.
4. Click on all the tabs. You will see all the settings. Some of them are important to know:

• Port: 21
• Enable Logging: checked
• Log File Directory: C:\WINDOWS\System32\LogFiles
• Log File Name: msftpsvc1\exyymmdd.log
• Allow Anonymous Connections: checked
• FTP Site Directory Local Path: c:\inetpub\ftproot

5. Right mouse click on the "Default FTP Site", and select Start. Your FTP server should be running now.
6. Test your FTP server, run the commands in a command window:
>ftp localhost
Connected to localhost.
220 Microsoft FTP Service
User (localhostnone)): anonymous
331 Anonymous access allowed, send identity (e-mail name) as password.
Password: me@herongyang.com
230 Anonymous user logged in.
ftp> dir
200 PORT command successful.
150 Opening ASCII mode data connection for /bin/ls.
226 Transfer complete.
ftp> quit
FTP Command Line Client Program
Windows XP comes with a FTP command line client program, c:\windows\system32\ftp.exe. Once it's launched, it takes FTP commands from the keyboard. Here are some useful used FTP commands:

• open "host_name" - Establishes a connect to the FTP server at the specified host.
• disconnect - Stops the current connect.
• user "user_name" - Provides user name and password to pass the access authentication.
• quit - Quits the FTP program.
• dir - Displays the contents of the current directory on the server.
• cd "relative_path" - Changes the current directory to specified path on the server. "cd .." changes the current directory one level up in the directory tree.
• lcd "relative_path" - Changes the current directory to specified path on the local system.
• get "file_name" - Downloads the specified file from the server.
• put "file_name" - Uploads the specified file to the server.
• mget "*.*" - Downloads the specified multiple files from the server.
• mput "*.*" - Uploads the specified multiple files to the server.
• !dir - Displays the contents of the current directory on the local system.
• type "binary|ascii" - Changes the file transfer type to binary or ASCII. In binary type, files will be transferred as is. In ASCII type, files will be transferred with automatic conversion to match the receiving system file format. For example, a text file on a Unix FTP server will be downloaded to a Windows local system with line feed character being converted to two characters, line feed and carriage return.
• prompt - Switches on or off the prompt for confirmation when using the mget and mput commands.
• help - Displays all available commands supported by the FTP client program.

Below is a list of all available commands supported by Windows command line FTP client program:
ftp> help Commands may be abbreviated. Commands are: ! delete literal prompt send ? debug ls put status append dir mdelete pwd trace ascii disconnect mdir quit type bell get mget quote user binary glob mkdir recv verbose bye hash mls remotehelp cd help mput rename close lcd open rmdir Downloading Files
Now, let's see how we can put some files on the FTP server to allow other users to download them.
Copy files to the FTP server directory in a command window:
>copy ftp.html c:\inetpub\ftproot 1 file(s) copied. >copy index.html c:\inetpub\ftproot 1 file(s) copied. >copy reference.html c:\inetpub\ftproot 1 file(s) copied.
Download them with the FTP client in a command window:
>ftp localhost
Connected to localhost.
...
ftp> dir
200 PORT command successful.
150 Opening ASCII mode data connection for /bin/ls.
11:05PM 5537 ftp.html
03:43PM 5082 index.html
08:39PM 1174 reference.html
226 Transfer complete.
ftp: 155 bytes received in 0.00Seconds 155000.00Kbytes/sec.
ftp> mget *.*
200 Type set to A.
mget ftp.html? y
200 PORT command successful.
150 Opening ASCII mode data connection for ftp.html(5537 bytes).
226 Transfer complete.
ftp: 5537 bytes received in 0.01Seconds 553.70Kbytes/sec.
mget index.html? y
200 PORT command successful.
150 Opening ASCII mode data connection for index.html(5082 bytes).
226 Transfer complete.
ftp: 5082 bytes received in 0.01Seconds 508.20Kbytes/sec.
mget reference.html? y
200 PORT command successful.
150 Opening ASCII mode data connection for reference.html(1174 bytes).
226 Transfer complete.
ftp: 1174 bytes received in 0.00Seconds 1174000.00Kbytes/sec.
ftp> quit

Cool, downloading files are easy. The "mget" command allows you to get multiple files with one command.
Checking the Log File
If you look the settings, you will find out that the log file is located in C:\WINDOWS\System32\LogFiles\MSFTPSVC1 directory. Open the last log file, exnnnnnn.log, you should see something like:
#Software: Microsoft Internet Information Services 5.1
#Version: 1.0
#Date: 03:55:34
#Fields: time c-ip cs-method cs-uri-stem sc-status
03:55:34 127.0.0.1 [1]USER anonymous 331
03:55:42 127.0.0.1 [1]PASS me@herongyang.com 230
03:55:49 127.0.0.1 [1]QUIT - 226
04:07:57 127.0.0.1 [2]sent /ftp.html 226
04:07:57 127.0.0.1 [2]sent /index.html 226
04:07:58 127.0.0.1 [2]sent /reference.html 226
To upload files, run the FTP client in a command window:
>ftp localhost Connected to localhost. 220 Microsoft FTP Service User (localhostnone)): herong 331 Password required for herong. Password: ******** 230 User herong logged in. ftp> dir 200 PORT command successful. 150 Opening ASCII mode data connection for /bin/ls. 11:05PM 5537 ftp.html 03:43PM 5082 index.html 08:39PM 1174 reference.html 226 Transfer complete. ftp: 155 bytes received in 0.00Seconds 155000.00Kbytes/sec. ftp> put help.html 200 PORT command successful. 150 Opening ASCII mode data connection for help.html. 226 Transfer complete. ftp: 728 bytes sent in 0.00Seconds 728000.00Kbytes/sec. ftp> dir 200 PORT command successful. 150 Opening ASCII mode data connection for /bin/ls. 11:05PM 5537 ftp.html 11:53PM 728 help.html 03:43PM 5082 index.html 08:39PM 1174 reference.html 226 Transfer complete. ftp: 205 bytes received in 0.00Seconds 205000.00Kbytes/sec. ftp> quit 221 Note that:

• To access the FTP server, you need provide a user name and a password of the server's Windows system.

Conclusion

• Windows provides FTP server service through IIS (Internet Information Services), which is relatively easy to manage.
• Windows also provides a command line client FTP program. If you are interested in client programs with graphical user interface, there are a number of shareware available on the Interface.
• You should be careful about running your FTP server with anonymous option turned on. Anonymous option allows anyone on the Internet to come to your server and take files away from FTP directory.

03:55:49 127.0.0.1 [1]QUIT - 226
Interesting, it did not record the "dir" command.
Uploading Files
Allowing other users to upload files to your FTP server needs some extra security settings. So let's re-visit the IIS FTP Server settings:
1. Run IIS, and open the Default FTP Site properties dialog box.
2. Visit the Security Accounts and Home Directory tabs, and making the following changes:

• Allow Anonymous Connections: unchecked - To stop other users accessing your FTP server anonymously. The server can only be accessed now by admin users registered on your machine.
• FTP Site Directory Write: checked - To allow other users to upload files.

Congratulations, you have created a working anonymous FTP server!
