centOS下安装ettercap

ettercap下载地址
http://ettercap.sourceforge.net/download.php

下载好之后解压出来,进入到解压目录

#tar zxvf  ettercap-NG-0.7.3.tar.gz#cd ettercap-NG-0.7.3

阅读README

# vim README

MANDATORY: //安装必须依赖的

• libpcap >= 0.8.1
• libnet >= 1.1.2.1
• libpthread
• zlib

OPTIONAL: //下面的是可选的

To enable plugins:
- libltdl (part of libtool)

To have perl regexp in the filters:
- libpcre

To support SSH and SSL decryption:
- openssl 0.9.7

For the cursed GUI:
- ncurses >= 5.3

For the GTK+ GUI:
- pkgconfig >= 0.15.0
- Glib >= 2.2.2
- Gtk+ >= 2.2.2
- Atk >= 1.2.4
- Pango >= 1.2.3

百度云分享三个必须依赖的lib文件
libpcap-1.7.4.tar.gz
libnet-1.1.2.1.tar.gz
zlib-1.2.8.tar.xz
下载到本地之后解压出来进入目录,一个一个安装

# ./configure# make# make install

注意：.tar.xz的解压命令是

# xz -d [filename].tar.xz# tar xvf [filename].tar

如果不安装会有类似的提示

configure: error: libpcap not found
configure: error: libpcap not found

确定都装上之后，继续进入ettercap的目录进行安装

[root@localhost ettercap-NG-0.7.3]# ./configure.........configure: error: Package requirements (gtk+-2.0 >= 2.0.0 pango >= 1.0 atk >= 1.0) were not met.Consider adjusting the PKG_CONFIG_PATH environment variable if youinstalled software in a non-standard prefix.Alternatively you may set the GTK_CFLAGS and GTK_LIBS environment variablesto avoid the need to call pkg-config.  See the pkg-config man page formore details.[root@localhost ettercap-NG-0.7.3]#

继续错误提示:
configure: error: Package requirements (gtk+-2.0 >= 2.0.0 pango >= 1.0 atk >= 1.0) were not met.
gtk+-2.0、pango、atk，这三个包不符合要求，可能是版本太低。

查到gtk+的安装方法，按下面顺序一个一个装：

1）pkg-config (pkg-config Site)
2)GNU make (GNU make Site)
3)JPEG, PNG and TIFF image libraries (GTK+ Site)
4)FreeType (FreeType Site)
5)fontconfig (fontconfig Site)
6)GNU libiconv library (if your system doesn’t have iconv()) (GNU libiconv Site)
7)GNU gettext (if your system doesn’t have gettext()) (GTK+ Site)
8)GLib (GTK+ Site)
9)Pango (GTK+ Site)
10)ATK (GTK+ Site)
11)GTK+ (GTK+ Site)

还得自己一个包一个包的去搜，然后下载下来安装。如果不嫌麻烦的可以采用上面的11个步骤。

这里提供一条代码安装的，不过这个方法按道理说不是很严谨。

# yum install gtk*

等待安装完毕之后再重新执行./configure

[root@localhost ettercap-NG-0.7.3]# ./configure.........ettercap has been configured as follow...================================================== Install directory:  /usr/localLibraries : LIBPCAP ................  default LIBNET .................  default LIBSSL .................  default NCURSES ................  NO GTK+ ...................  yesFunctionalities : Debug mode .............  no Plugin support .........  no Passive DNS ............  no Perl regex in filters ..  no Iconv UTF-8 support ....  yes==================================================[root@localhost ettercap-NG-0.7.3]#

如果依赖库的问题都没有了的话，会出现这个提示
表示目前系统支持的函数库和功能。
如果想拥有全部的功能，可以查看README文档，把里面的可选组件都装上。

接着执行make和make install

[root@localhost ettercap-NG-0.7.3]# make&&make install

如果运行ettercap出现下面的内容，表示安装成功了。

[root@localhost ettercap-NG-0.7.3]# ettercap
