Scapy is a (mostly) cross-platform packet manipulation tool. This allows you to craft and edit packets that you then send to other hosts when you open a socket. This is incredibly useful for, for example, capturing a packet being sent to you, manipulating the payload, and passing the packet on to another host. This is a pretty common, albeit slightly more advanced, method of security testing. Installing Scapy is a pretty straight forward process, if a tad bit time consuming compared to something coming in from a standard package.Before you get started, make sure you have the OS X Developer Tools installed from the. Cakewalk pro audio 9 for mac. Also, make sure you have ports installed from. You’ll also need pylibpcap, as with most packet manipulation tools, so install that from Install Pylibpcap, Download from.

To edit, you have to be the administrator, copy the file to some other location, edit it and then copy it back to the etc directory.I do not recommend the change of the hosts file. Wampserver apache not starting. You can do that by editing the hosts file in your system directory.The file is placed at: C:WindowsSystem32driversetchostsby default windows 7 ships with: # localhost name resolution is handled within DNS itself.# 127.0.0.1 localhost#::1 localhostYou have to un-comment the mapping for localhost: # localhost name resolution is handled within DNS itself.127.0.0.1 localhost#::1 localhostNote: you will not be able to edit the hosts file as its a read-only file.

Then there are some dependencies we’ll grab from Mac Ports:port selfupdateport upgrade outdatedport install py27-libdnetport install libdnetNext, download scapy from. Once downloaded, cd into the scapy directory:cd /Downloads/scapy-.Then run the python installer:sudo python setup.py installOnce installed, then start scapy with:sudo scapyNext, we’ll read a pcap file, which I have at /Documents/mypcap a=rdpcap('/spare/captures/isakmp.cap') aYou can also build a custom packet, using a=IP(ttl=10) a a.src’192.168.210.10’ a.dst='192.168.210.11' a a.src’192.168.210.10’ del(a.ttl) a a.ttl64So far, very basic. We’ve read a packet and we’ve created a packet. Use send to send a packet: send(IP(dst='192.168.210.11')/ICMP)You can also add a Fuzz option, to get into fuzzing, and use sr1 to send and receive packets, rather than just send (thus allowing you to view the response).
