"checking for libnet_build_ip in -lnet... no"+"ERROR! Libnet library not found"

It can happen that nemesis installation to fail because the configure script cannot find libnet. THis is not nemesis's fault, it's the admin's fault (mine and yours

).
Nemesis configure script error:

Quote:

checking for an ANSI C-conforming const... yes
checking for gawk... (cached) gawk
checking for a BSD-compatible install... /usr/bin/install -c
checking whether ln -s works... yes
checking for fabs in -lm... yes
checking for inet_ntoa in -lnsl... yes
checking for socket in -lsocket... no
checking for hstrerror in -lresolv... yes
checking for libnet_build_ip in -lnet... no

ERROR! Libnet library not found, go get it from
http://www.packetfactory.net/projects/libnet/
or use the --with-libnet-* options, if you have it installed
in unusual place

The nemesis project website instructs that nemesis requires libnet-1.0.2a, not first libnet source that falls in our hands (the official website was down).

The correct libnet contains a folder named "Libnet-1.0.2a" and not "libnet".

Go and download the correct libnet source file from http://code.google.com/p/ips-builder/downloads/detail?name=libnet-1.0.2a.tar.gz&can=2&q= and follow my post on how to install libnet library and nemesis packet crafting tool:
http://forum.ivorde.ro/centos-install-nemesis-packet-crafting-tool-libnet-t134.html

This solved the "checking for libnet_build_ip in -lnet... no"+"ERROR! Libnet library not found" for me and allowed me to continue installing nemesis tool.

Since Nemesis development stopped a long time ago, it doesn't compile by default on x86_64 architectures. Following error will appear.

Code:

 nemesis-1.4]# make

Edit "/usr/include/libnet/libnet-headers.h" file (use your specific location) and change:

Code:

#if (!__GLIBC__)
struct ether_addr
{
    u_char  ether_addr_octet[6];
};
#endif

Code:

//#if (!__GLIBC__)
struct ether_addr
{
    u_char  ether_addr_octet[6];
};
//#endif
