Configuring FTP Site Properties
To
configure settings for an FTP site, right-click the site object in IIS
6.0 Manager and select Properties. You can change the IP address and
TCP port properties for the site on the FTP Site tab. (See Figure 5.) To make these changes effective, you will need to restart the FTP site.
The
FTP Site Connections section enables you to specify connection-related
limits. The default settings are to allow up to 100,000 connections and
for inactive connections to time out after 120 seconds. If you want to
limit the amount of bandwidth and resources that specific sites use
within the FTP publishing service, you can configure them here.
Important: Connection limits
FTP
servers, especially those accessible from the Internet, are often
targets for unauthorized usage attempts. Users will sometimes connect
to an insecure FTP server to provide others access to their own
uploaded content. Settings such as a limit on the number of connections
can help ensure that the site is being used only by authorized users.
For example, if you are expecting only a few occasional users to access
the site, lower the default limit. Although connection limits should
not be used in place of security methods, they can help avoid certain
types of misuse.
In
the Enable Logging section, click the Properties button to display the
Logging Properties dialog box. This enables you to specify when new log
files are created and where they are stored. (See Figure 6.)
You can also specify which information is collected by using the
properties on the Advanced tab. Adding more information to the log
files will increase log file size but can provide more details about
the site. Log files are plaintext files and can be opened in a text
editor such as Windows Notepad.
The
Current Sessions button on the FTP Site tab enables you to view which
users are currently connected to the server. This information can be
helpful for troubleshooting potential performance issues and for
tracking how the site is being used at a given time.
