2.2. Information Administrative Window

2.2.1. Status

By selecting the Information AW you are presented with a VERY thorough list of information regarding the current status of your IPCop server. The first subsection status displays the following in top-down order:

  • Services - Displays which services are currently running.

  • Memory - Displays the memory/swapfile usage on your IPCop server.

  • Disk Usage - Displays the total/used amount of Harddrive space on your IPCop server.

  • Uptime and Users - Displays the output of the uptime command and information on users currently logged in on the IPCop server.

  • Interfaces - This section displays information on all your network devices. This includes PPP, IPSec, Loopback etc.

  • Loaded Modules - This displays all modules currently loaded and in use by the kernel.

  • Kernel Version - This displays information on the IPCop Kernel itself.

2.2.2. Traffic Graphs

This page gives a graphic depiction of the traffic in and out of the IPCop box. The first section, GREEN Traffic, shows activity on the internal ethernet port.

The second section, labelled RED Traffic, shows a graph for all incoming and outgoing traffic through the red interface to the outside world.

2.2.3. Proxy Graphs

This page shows traffic through the proxy service of the IPCop box. The first section, Proxy access graphs: gives the date and time the graph was created, the lines analyzed, the duration of the analysis, the speed (lines per second), the start and end date and time of the graph, and the domain (overall length of the graph in time).

This information is useful in seeing whether the proxy is the correct size for the load being experienced.

2.2.4. Connections

IPCop uses the Linux Netfilter or IPTables firewall facility to maintain a stateful firewall. Stateful firewalls keep track of connections to and from all GREEN and ORANGE network IP addresses, based on both the source and destination IP addresses and ports, as well as the state of the connection itself. After a connection is established involving protected machines, only packets consistent with the current state of the connection are allowed through the IPCop firewall.

The IPTables Connection Tracking: shows the IPTables connections. Connection end points are color coded based on their network location. The color coding legend is displayed at the top of the page. Information on individual connections is displayed next. Each connection from or to your networks is shown.
