The following instructions apply if you have a Linux platform and want libpcap to support the Septel range of passive network monitoring cards from Intel (http://www.intel.com) 1) Install and build the Septel software distribution by following the instructions supplied with that package. 2) Configure libcap. To allow the 'configure' script to locate the Septel software distribution use the '--with-septel' option: ./configure --with-septel=DIR where DIR is the root of the Septel software distribution, for example /var/src/septel. By default (if you write only ./configure --with-septel) it takes ./../septel as argument for DIR. If the Septel software is correctly detected 'configure' will report: checking whether we have Septel API... yes If 'configure' reports that there is no Septel API, the directory may have been incorrectly specified or the Septel software was not built before configuring libpcap. See also the libpcap INSTALL.txt file for further libpcap configuration options. Building libpcap at this stage will include support for both the native packet capture stream and for capturing from Septel cards. To build libpcap with only Septel support specify the capture type as 'septel' when configuring libpcap: ./configure --with-septel=DIR --with-pcap=septel Applications built with libpcap configured in this way will only detect Septel cards and will not capture from the native OS packet stream. Note: As mentioned in pcap-septel.c we should first edit the system.txt file to change the user part example (UPE) module id to 0xdd instead of 0x2d for technical reason. So this change in system.txt is crucial and things will go wrong if it's not done. System.txt along with config.txt are configuration files that are edited by the user before running the gctload program that uses these files for initialising modules and configuring parameters. ---------------------------------------------------------------------- for more information please contact me : gil_hoyek@hotmail.com
