 Once the kernel is built and running, it will automatically begin  
collecting data on every TCP connection to/from the server. The user  
library file contains the routines needed to extract that kernel data from  
the system. The administrator can verify that the kernel is recording  
properly by using the /usr/local/bin/gutil program. This X-windows based  
GUI allows the administrator to monitor any TCP connection going to/from  
the server.

+==== pcap library ====
+
+The pcap library provides raw access to the network interface. The NDT  
uses packet pair dispersion techniques to determine the bottleneck link  
speed/type. This means that the _libpcap.so_ runtime libraries must be  
installed on the NDT server. This library is a standard part of all Linux  
distributions. The administrator should check the NDT server to ensure they  
were installed when the system was built. The command:
+
+{{{ls /usr/lib/libpcap*}}}
+
+– will return several files if the libraries are installed. If they are  
not installed, obtain the installation package from your favorite mirror  
site or download and install the source from the [http://www.tcpdump.org]  
web site.
