libnids 安装编译与测试

一、linux下编译安装libnids库

1、安装libpcap(略)

2、安装libnet:

源文件下载地址:http://sourceforge.net/projects/libnet-dev/files/
解压:tar -zxvf libnet-1.2-rc3.tar.gz

cd libnet-1.2-rc3
./configure
make
make install

安装完以后,配置一下动态库路径,否则libnids编译时找不到
cat /etc/ld.so.conf
////显示内容 include ld.so.conf.d/*.conf
echo “/usr/local/lib” >> /etc/ld.so.conf
ldconfig

3、安装libnids:

源文件下载地址:http://sourceforge.net/projects/libnids/files/
解压:tar -zxvf libnids-1.24.tar.gz

cd libnids-1.24
./configure
make
make install

我用的是centos6.5,会configure会提示出错
configure: error: Cannot find eventlog version >= 0.2: is pkg-config in path
解决方案: 安装glib2-deve
yum -y installglib2-devel

4、用gcc编译源文件时后面加上:-lpcap -lnet -lnids -lgthread-2.0,因为libnids 1.22以后使用了,glib2库中的gthread-2.0来实现多线程提高效率,因此在编译除了-lnids -lpcap -lnet 以外还要加上 -lgthread-2.0

5、编译用 g++编译时出错,gcc编译提示警告,g++版本4.94

g++ hello.cpp -lpcap -lnet -lnids -lgthread-2.0

hello.cpp:149:44: 错误:从类型‘void (*)(tcp_stream*, void**)’到类型‘void*’的转换无效 [-fpermissive]
     nids_register_tcp(tcp_protocol_callback);       /*注册回调函数*/   
                                            ^
In file included from hello.cpp:1:0:
/usr/local/include/nids.h:149:6: 附注:initializing argument 1 of ‘void nids_register_tcp(void*)’
 void nids_register_tcp (void (*));

在nids.h中把头文件改了,或者把参数用(void*)强制转换

void nids_register_tcp (void (*));

修改头文件,改成如下声明,参考https://linux.die.net/man/3/libnids

void nids_register_tcp(void (*tcp_func)(struct tcp_stream *ts, void **param));

编译通过

二、Windows下编译使用libnids库

1、前期准备
目前网上的能稳定支持windows的libnids版本为libnids-W32-1.19。网上搜一下有很多,随便下一个并解压缩。由于libnids需要使用winpcap,所以要先下载并安装winpcap。到http://www.winpcap.org/install/default.htm下载最新版winpcap的安装包,然后到http://www.winpcap.org/devel.htm下载程序员开发包。安装winpcap。将libnids-W32-1.19的WIN32-Includes文件夹下文件存至另一个文件夹中(记为include文件夹)。将libnids-W32-1.19的WIN32-LIbraries文件夹下的库,和winpcap程序员开发包WpdPack文件夹中Lib文件夹中的Packet.lib和wpcap.lib放到一个文件夹中(记为lib文件夹)。

2、重新编译libnids库
在目录 WIN32-PRJ中,找到 libnids.dsw ,这个是6.0版本的,我用的是VS2015,打开,重新编译,生成libnids.lib,目前只要这个,把库移动到1中提到的lib文件夹下

3、测试libnids库
新建项目,加入测试代码如下:

#include <iostream>
#include "nids.h"
using namespace std;

#pragma comment(lib, "ws2_32.lib")
#pragma comment(lib, "wpcap.lib")
#pragma comment(lib, "Packet.lib")
#pragma comment(lib, "libpcap.lib")
#pragma comment(lib, "libnids.lib")

#pragma warning(disable:4996)

//libnidsTest.cpp: 定义控制台应用程序的入口点。


char ascii_string[10000];
char*char_to_ascii(char ch)
/* 此函数的功能主要用于把协议数据进行显示 */
{
    memset(ascii_string, 0x00, 10000);
    char * string = ascii_string;

    if (ch >= 32 && ch <= 126)
    {
        *string++ = ch;
    }
    else if (ch == '\n' || ch == '\r')
    {
        *string++ = ch;
    }
    else
    {
        //其它字符以点"."表示
        *string++ = '.';
    }

    return ascii_string;
}

编译提示出错,大概如下

errorLNK2019: 无法解析的外部符号 "int __cdeclnids_init(void)" (?nids_init@@YAHXZ) ,该符号在函数 _main 中被引用 
errorLNK2001: 无法解析的外部符号 "char *nids_errbuf" (?nids_errbuf@@3PADA) 
errorLNK2001: 无法解析的外部符号 "structnids_prm nids_params" (?nids_params@@3Unids_prm@@A) 等错误

需要修改nids.h头文件,找到int nids_init ();一行,在该行前加上如下代码:

#ifdef __cplusplus
extern "C"{
#endif

在头文件尾加上

#ifdef __cplusplus
}
#endif

1.19的头文件最终改成如下

Libnids抓不到包的问题
运行后,如果出现一直抓不到数据包的情况,其实是网卡驱动没选好。所以我们在main()函数中第一行,添加一句代码:nids_params.device=”2”;将适配器设为真正起作用的设备。修改后的main()函数如下:

int main()
{
nids_params.device =”2”;

if(!nids_init())
{
printf(“出现错误:%s\n”, nids_errbuf);
exit(1);
}
printf(“初始化成功!\n”);
nids_register_tcp(tcp_protocol_callback);
nids_run();
}
如果还不行,就试试3、4…等等。
