linux ettercap,CentOS下安装ettercap[通俗易懂]

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 READMEMANDATORY: //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
