Installation of the Libsf distribution requires two phases. First, build and install the library:
tradecraft:/usr/local/src/libdnet-1.0# ./configure && make && make install
Next, create and install the active and passive fingerprint databases. You build the active database from an unmodified nmap fingerprint database (a copy of which comes with libsf):
tradecraft:/usr/local/src/libdnet-1.0/import# ./db_import -a nmap- fingerprint.txt && cp libsf.db /usr/local/share/libsf
The passive database is a simple flatfile (a copy of which comes with libsf):
tradecraft:/usr/local/src/libdnet-1.0/import# cp libsf-p.txt /usr/local/share/libsf
