If a plugin fails to initialize, it will automatically be disabled. For example, db_dump plugin may fail if you haven't set up a MySQL database with DBI interface. You may encounter warnings with several plugins.
Once you obtained the output file, run the scripts on it at once by using this command: $ cd httpry/scripts db_dump: Dump log file data into a MySQL database.īefore using these scripts, first run httpry with -o option for some time.log_summary: Generate a summary of log.xml_output: Convert output into XML format.content_analysis: Find URIs which contain specific keywords.search_terms: Find and count search terms entered in search services.hostnames: Display a list of unique host names with counts.If you want to write a custom parser for httpry's output, these scripts can be good examples to start from. These scripts are found in httpry/scripts/plugins directory.
HTTP SNIFFER SCRIPT CODE
If you downloaded httpry's source code, you will notice that the source code comes with a collection of Perl scripts which aid in analyzing httpry's output. If you want to monitor only specific HTTP methods (e.g., GET, POST, PUT, HEAD, CONNECT, etc), use -m option: $ sudo httpry -i eth0 -m get,head To save httpry's output to a text file: $ sudo httpry -i eth0 -o output.txt Note that when you read a dump file with -r option, you don't need root privilege. To replay saved HTTP packets: $ httpry -r output.dump To save raw HTTP packets into a binary file: $ sudo httpry -i eth0 -b output.dump On the other hand, -o option saves human-readable output of httpry into a text file. The -b option allows you to save raw HTTP packets into a binary file as is, which then can be replayed with httpry later. So you want to save captured HTTP packets for offline analysis. In most cases, however, you will be swamped with the fast scrolling output as packets are coming in and out. Httpry then listens on a specified network interface, and displays captured HTTP requests/responses in real time. The basic use case of httpry is as follows.
HTTP SNIFFER SCRIPT INSTALL
You can easily build httpry from the source by: $ sudo yum install gcc make git libpcap-devel On Fedora, simply run: $ sudo yum install httpry So build it from the source: $ sudo apt-get install gcc make git libpcap0.8-devįirst, enable EPEL repo, and then use yum command: On Debian-based systems, httpry is not available in base repositories. Install httpry on Linux Install httpry on Ubuntu or Debian In this tutorial, let's see how we can sniff HTTP traffic with httpry. httpry captures live HTTP packets on the wire, and displays their content at the HTTP protocol level in a human-readable format. In fact, httpry is extactly that: HTTP packet sniffing tool.
What will be nice is to have tcpdump-like sniffing tool, but targeting HTTP traffic only.

Real-time web server log parsers such as ngxtop provide human-readable real-time web traffic traces, but only applicable with a full access to live web server logs. While packet sniffing tools such as tcpdump are popularly used for live packet dump, you need to set up proper filtering to capture only HTTP traffic, and even then, their raw output typically cannot be interpreted at the HTTP protocol level so easily. Whatever the reason is, there are cases where HTTP traffic sniffing is helpful, for system admins, developers, or even end users. Or you may be trying to troubleshoot PAC (proxy auto config) or check for any malware files surreptitiously downloaded from a website. Or you may be debugging a web application or a RESTful service. For example, you may be testing experimental features of a web server. Suppose you want to sniff live HTTP web traffic (i.e., HTTP requests and responses) on the wire for some reason.
