I'm working through Intrusion Detection With BASE And Snort tutorial (http://www.howtoforge.com/intrusion_..._base_snort_p3
) on Ubuntu. I ran into a problem at make/install LIBPCAP (page 3). When I execute ./configure, I get the following error:
configure: error: Your operating system's lex is insufficient to compile
libpcap. flex is a lex replacement that has many advantages, including
being able to compile libpcap. For more information, see
I'm familiar with Linux and Ubuntu, but not knowlegeable enough to know how to resolve this problem.
Can anyone help?
