（一）安装
1. 安装依赖 
sudo apt-get install python-crypto python-dpkt python-ipy python-pypcap
sudo pip install pygeoip

2. 把GeoIP.dat, GeoIPv6.dat, GeoIPASNum.dat, GeoIPASNumv6.dat移到/share/GeoIP/文件夹下
3. make
4. ./dshell
如果出现Dshell>，那么成功

（二）使用
引用
1. decode -l
列举可使用的decoder和他们的基本信息
2. decode -h
大部分decoder的共同信息
3. decode -d <decoder>
显示一个decoder的信息
4. decode -d <decoder> <pcap>
在指定的pcap上运行decoder


（三）使用例子
显示DNS查询，样本http://wiki.wireshark.org/SampleCaptures#General_.2F_Unsorted
