centOS下安裝ettercap

ettercap下載地址
http://ettercap.sourceforge.net/download.php

下載好之後解壓出來,進入到解壓目錄

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

閱讀README

# vim README

MANDATORY: //安裝必須依賴的

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

OPTIONAL: //下面的是可選的

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

百度雲分享三個必須依賴的lib文件
libpcap-1.7.4.tar.gz
libnet-1.1.2.1.tar.gz
zlib-1.2.8.tar.xz
下載到本地之後解壓出來進入目錄,一個一個安裝

# ./configure
# make
# make install

注意：.tar.xz的解壓命令是

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

如果不安裝會有類似的提示

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

確定都裝上之後，繼續進入ettercap的目錄進行安裝

[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 you
installed software in a non-standard prefix.

Alternatively you may set the GTK_CFLAGS and GTK_LIBS environment variables
to avoid the need to call pkg-config.  See the pkg-config man page for
more details.
[root@localhost ettercap-NG-0.7.3]#

繼續錯誤提示:
configure: error: Package requirements (gtk+-2.0 >= 2.0.0 pango >= 1.0 atk >= 1.0) were not met.
gtk+-2.0、pango、atk，這三個包不符合要求，可能是版本太低。

查到gtk+的安裝方法，按下面順序一個一個裝：

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)

還得自己一個包一個包的去搜，然後下載下來安裝。如果不嫌麻煩的可以採用上面的11個步驟。

這裏提供一條代碼安裝的，不過這個方法按道理說不是很嚴謹。

# yum install gtk*

等待安裝完畢之後再重新執行./configure

[root@localhost ettercap-NG-0.7.3]# ./configure
...
...
...

如果依賴庫的問題都沒有了的話，會出現這個提示

接着執行make和make install

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