网络流量限制

The internet control module is able to perform any of the following functions:

• Charge your users for their Internet access
• Place Internet quotas on your users
• Silently monitor your users' Internet usage (used by many businesses)
• Disallow Internet access once users run out of credit

PaperCut internet control allows you to charge/quota users based on either the time they spend on the internet or the amount of data they download, or a combination of both.

按时限制

• Stops people wasting time surfing the web
• Useful when computer resources are scarce
• Charge for time used, not data downloaded
• Easy for your users to understand
• Choose a time period duration and a cost per period

按数据流量限制

• Useful when bandwidth is expensive
• Encourages careful use of bandwidth
• Stops people downloading large files like video and streaming audio

PaperCut requires a supported proxy server to track and restrict the Internet access. The following proxies are supported:

	Supported Log Format	Can deny access
Squid (More info ...)		when using: Squid with Active Directory, or with Samba 3.0.7+ and Winbind
SquidNT "Squid for Windows" (More info ...)
MS ISA Server 2000/2004/2006 (More info ...)
MS Proxy Server
Free Proxy (More info ...)	(using W3C log format)

控制网络使用

• Charge by data transfer, time used or a combination of both
• Optionally don't charge for cached data, upstream data or a list of sites

管理网络使用

• Set reasonable limits for internet usage
• Charge / quota users by data transfer, time used or a combination of both

  How time based charging works:

  1. You choose the duration of each chargeable time period
  2. Each day is split into time periods of this duration
  3. When a user accesses the Internet within a time period, they are charged for using that period
  4. The defined charge for the period will be deducted from the user's account
  5. If the user has no credit, they will be disallowed access to the Internet
• Optionally don't charge for cached data, upstream data or certain sites
