    Exclamation unicornscan fails to start. cannot open shared library libpcap.so.0.8, no such file.

    Error experienced in VirtualBox 64bit GNOME environment.
    In reference to http://www.backtrack-linux.org/wiki/...hp/Unicornscan

    Code:
    #unicornscan -epgsqldb <TARGET IP>
    unicornscan: error while loading shared libraries: libpcap.so.0.8: cannot open
    shared object file: No such file or directory
    Code:
    #whereis libpcap.*
    libpcap: /usr/lib/libpcap.so /usr/lib/libpcap.a /usr/lib64/libpcap.so /usr/lib64/libpcap.a
    Oddly enough, $LD_LIBRARY_PATH returns null after a fresh BT5 install. I would figure at least the shared libraries paths would be listed here. Even after manually updating $LD_LIBRARY_PATH, deleting libpcap.so and finally soft linking libpcap0.8.so to libpcap.so, unicorn throws the same error.

    Code:
    apt-get install --reinstall libpcap0.8
    Does not help either.

    Has anyone else noticed this yet?

    I've got the same issue here on BT5-KDE-64 =(
    Code:
    root@bt:~# ldd /usr/local/bin/unicornscan
            linux-gate.so.1 =>  (0xf77b7000)
            libpcap.so.0.8 => not found
            libltdl.so.3 => not found
            libdumbnet.so.1 => not found
            libc.so.6 => /lib32/libc.so.6 (0xf763b000)
            /lib/ld-linux.so.2 (0xf77b8000)
    Code:
    root@bt:~# locate libltdl.so.3 libpcap.so.0.8 libdumbnet.so.1
    /opt/framework3/lib/libpcap.so.0.8
    /usr/lib/libdumbnet.so.1
    /usr/lib/libdumbnet.so.1.0.1
    /usr/lib/libpcap.so.0.8

    I can also verify this in gnome 64 installed to hard drive.

    It was with this same problem, solved with a little line:

    Code:
    cp /usr/share/GeoIP/GeoIP.dat /usr/local/etc/unicornscan/
