Hi, I am working on project Signature Based IDS. For that reason I need to install libpcap on my machine. I have problem in installing.I have libpcap source directory. as I give command # ./configure I found 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 http://www.gnu.org/software/flex/flex.html .
please help in installing libpcap.Step by step. Thanks in advance.
Is there any reason you're trying to build it from source rather than installing it from the package repository?
sk:~# apt-cache search libpcap | grep ^libp
libpcap-dev - Development library for libpcap (transitional package)
libpcap-ruby1.8 - Ruby interface for the libpcap packet capture library
libpcap0.7 - System interface for user-level packet capture
libpcap0.7-dev - Development library and header files for libpcap 0.7
libpcap0.8 - System interface for user-level packet capture
libpcap0.8-dev - Development library and header files for libpcap 0.8
libpcap0.9 - Dummy package, can be safely removed
libpcap0 - System interface for user-level packet capture.
sk:~# apt-get install libpcap-dev
You could just install it with libaptituted unless you *want* to build it from source. You could also use aptitude to build from source:
I don't have internet connection that is why I am installing from source instead of repository.As I get internet connection I will try as you said. I think what ever you have given those are commands which I have to run. I am new to linux. Thank you sknake.

Hi arunmagar, I don't know is it better to talk with you here or not, because I could not managed to find your mailing address. As I saw you were working on signature based IDS, I am also working on it but I have been stuck somewhere. I hope you are going to help to get me out of this
