Editcap Guide: 11 Examples To Handle Network Packet Dumps Effectively




 
Editcap utility is used to select or remove specific packets from dump file and translate them into a given format. Editcap does not perform packet captures like ethereal. Instead, it operates on the captured packets and writes some of the required packets into another file. We can pass various options to editcap to get our preferred packets.

In this article, let us review 11 practical examples on how-to use editcap to handle the packet dumps effectively.

Primary Purpose of editcap

Following are the main reason to use editcap command.

§  Divide a dump file into multiple files.

§  Select only the required packets.

§  Translate the capture file from one format to another.

§  Ability to read from a compressed dump file.

§  Make the job easier for network analyzer tool by loading only selective packets, instead of loading whole dump.

§  All feature results in less time consumption when processing or analyzing packets.


Let us assume the scenario where you have to analyze only some specific packet types in a huge dump file. In this situation, we cant use the network packet analyzer (wireshark or ethereal) to load the huge dump file in a single shoh, as it will be a CPU intensive process and the system may hang. Editicap utility makes the job easier by giving only relevant packets, so it could be loaded by network analyzer tool in quick time.

editcap is available in the wireshark package. Make sure wireshark/ethereal package is installed to use the editcap.
 

11 Practical Examples Of edicap Usage

Example 1: Discard set of packets from the beginning of input_dump file

The output_dump file will contain all packets except the first 10 packets.

# editcap -v input_dump output_dump 1-10

Example 2: Discard set of packets from the middle of input_dump file

The output_dump file will contain all packets except packets from 200 to 210.

# editcap -v input_dump output_dump 200-210

Example 3: Select multiple range of packets (from beginning and middle)

The output_dump file will contain first 10 packets and packets from 100 and 200.

# editcap -r  -v input_dump output_dump 1-10  100-200

Example 4: Change the encapsulation type of the capture file using option -T

By default the encapsulation type of the dump file is ether. The example below, translates the capture file into ieee-802-11-bsd format

# editcap -v -T  ieee-802-11-radiotap input_dump output_dump

Example 5: Process the compressed input_dump files

editcap automatically detects the compressed capture file formats. Currently it supports for the gzip format. In the example below, it takes packets from the compressed input file and writes the first 10 packets and the packets in-between 100 and 200 into the output_dump file.

# editcap -r -v input_dump.gz output_dump 1-10 100-200

Example 6: Extract packets between a specific timeperiod using option -A and -B

This example create the output_dump, which contains the packets that are captured between the time mentioned in option A and the time mentioned in option B.

# editcap -v -A "2009-02-11 11:26:30" -B "2009-02-11 11:27:00"  input_dump output_dump

Example 7: Change packet’s timestamp (reduce or advance) using option -t

To advances the timestamp of packets to one hour.

# editcap -t 3600 input_dump output_dump


To reduces the timestamp of packets to 30 minutes,

# editcap -t -1800 input_dump output_dump

Example 8: Remove duplicate packets from the output_dump file using option -d

The example below looks back the previous frames to find the duplication. Finally it gives the dump which does not contain duplication.

# editcap -v -d input_dump output_dump

Example 9: Truncate the packets to the specific length using option -s

Produces the ouptut_dump file with packets length limited to 100. This can be very helpful under lot of situations. For example, you can use this method if you want to get only the IP layer of all the packets and does not require other layer.

# editcap -s 100 -v -A "2009-02-11 11:26:30" -B "2009-02-11 11:27:00"  input_dump.gz output_dump

Example 10: Divide input_dump file into multiple files using option -c

Divide the single dump into multiple file and each contains specified number of packets.

# editcap -v -c 1000 input_dump output

 
If the input_dump contains 5000 packets, editcap will generate the following 5 different output files.

output-00000
output-00001
output-00002
output-00003
output-00004

Example 11: Remove certain bytes from the bottom of all packets using option -C

This example removes 10 bytes from every packets and writes into the output file. You can confirm this, by viewing the output file in wireshark, the frame layer of every packet will show “50 bytes bytes on wire, 40 bytes captured” (here the actual size of a packet is 50 bytes).

# editcap -C 10 input_dump output

 

 

7 Powerful Firefox Bookmark Add-ons To Enhance Your Browsing Experience


 

Like most of you, I’m a huge fan of Firefox and use it intensively both at home and work. There are lot of useful add-ons available for Firefox, which makes customizing the browser very easy. A while back we discussed about 7 Essential Firefox Security add-ons that will help you browse the internet securely.
 
In this article, let us discuss about 7 powerful Firefox bookmark add-ons along with screenshots that will enhance your browsing experience drastically.

Did I miss any of your favorite Firefox bookmark add-ons? Please leave a comment and let us know which one is your favorite Firefox bookmark add-ons from this list.
 

1. Foxmarks Bookmark Synchronizer

If you are using Firefox on multiple computers, Foxmark is an essential add-on. I use Windows laptop at work, Ubuntu laptop at home and Fedora server at home. On all these three systems the bookmarks on my Firefox browser is exactly the same. If I add a bookmark on my Firefox browser at work, Foxmarks syncs it across all my systems automatically.
 

Fig: Foxmarks Overview

 
Following are the main advantages of foxmarks:

§  Synchronize Firefox bookmarks across multiple systems

§  Backup your bookmark to a central server

§  View your bookmarks online anytime at my.foxmarks.com

§  Add tags while adding bookmarks

 
Password Synchronization is an optional feature that allows you to securely synchronize your saved passwords between your computers. With this feature, you can save your passwords at work and have them automatically available on your computer when you get home!
 
Foxmarks can also synchronize and backup your saved password. This is an optional feature that can be enabled if required. Please read Formarks wiki to understand this feature in detail.
 
To create a Foxmarks account, click on Tools Menu on the Firefox browser, -> Foxmarks -> Foxmarks Settings, which will display the Accounts Tab as shown below. Click on ‘Run Setup Wizard’ and follow the instructions.

 

Fig: Foxmarks Settings – Account Tab. (Tools Menu -> Foxmarks -> Foxmarks Settings)

 
If you are new to Foxmarks, this
 Video Tour will explain the details of how this add-on works.

2. Delicious Bookmarks

Delicious is the most popular social bookmarking site. For those who are used to the traditional way of organizing bookmarks using folders, delicious may be little different, where you should bookmark using tags. Once you get used to bookmarking using tags, you’ll never go back to organizing bookmarks using folder.
 
This add-on was developed by Yahoo!. After you’ve installed it, it will add the following three buttons on the Firefox tool bar next to the home button, as shown below.
 

Fig: Delicious Bookmark Buttons

 

1.    Bookmarks Button: This will open the delicious bookmark panel on the right side of the browser. To retrieve a bookmark, enter the tag in the search box in this side panel.

2.    Tag Button: When you are visiting a website, click on this button to bookmark, which will bring up the bookmark dialog as shown below, where you can add tags.

3.    Delicious Button: Clicking on this button will take you to delicious.com website, where it will display all your bookmarks.

 

Fig: Delicious bookmarks

 
You can also import your existing firefox bookmarks to delicious and share the bookmarks with your friends and family.

 Full Tour of delicious Firefox add-on.

3. Smart Bookmarks Bar

Smart bookmarks will save space on the bookmark toolbar by hiding bookmark names and display only the icons. When you mouse-over on a specific bookmark icon, it will display the full name of that particular bookmark.

4. ScrapBook

Following are few highlights of ScrapBook add-on:

§  Save a local copy of a webpage.

§  Save full or part of the webpage to your local system.

§  Specify whether you would like to download the image, music, movie or archive files that are located on a webpage that you are visiting

§  Perform a Full-text search on all the webpages that was captured

 
A new ScrapBook menu will be added to Firefox, which will give the following sub-menu items.

§  Capture Page

§  Capture Page As

§  Bookmark with Scrapbook

§  Capture all Tabs

§  Show in Sidebar

 
To get the ScrapBook option dialog, click on ‘Show in sidebar’ and click on the ‘Tools’ menu in the side bar and click on ‘Options”, which will display ScrapBook option dialog as shown below.

Fig: ScrapBook Options

5. Read It Later

Using Read It Later, you can save webpages to a reading list, which is different than bookmarking. For example, when you are visiting social media sites or news sites, you may not want to add all articles or news items to your bookmark. However, you may want to add it to your temporary reading list. Once you’ve read it, you can mark it as read, which will remove the news item from your reading list.  
You can also save the reading-list to your system for offline reading.
 

Fig: Read It Later reading list

The Read It Later Video Tutorial explains this in more detail.

6. UrlbarExt

This awesome add-on will add icons for the following features on the address bar.

§  Make Tiny URL

§  Copy URL

§  Search site

§  Go up

§  Tag pages easily

§  Navigate through sequential URL’s

§  View page cached version

§  Unblock filtered websites

§  Surf anonymously using online phproxy servers

Using the UrlBarExt option, you can choose what icons will be displayed on the address bar.

7. Fast Dial

Fast Dial is a visual bookmark. Install Fast Dial and press Ctrl+T to open a new tab in Firefix and launch the Fast Dial. You can also add “about:blank” as home page, to open Fast Dial while starting Firefox.
 
The Figure below shows how Fast Dial visual bookmark will look-like on a new Firefox tab, when you press Ctrl+T.
 

Fig: Fast Dial Visual Bookmark

 
Add a site to the Fast Dial visual bookmark using one of the following methods:

§  Right click on the website you are visiting and select ‘Add to Fast Dial’, which will add the website to one of the visual empty slots in the Fast Dial.

§  Click on one of the visual empty slots in the Fast Dial, which will prompt for the URL to be added.

 
You can also assign logos to the Fast Dial visual bookmark. There are lot of nice logos available from userlogos.org that you can use. Follow the steps below to add Google website to the Fast Dial and assign a logo.

§  Visit Google on your Firefox browser

§  Right Click on the Google home page and click ‘Add to Fast Dial’

§  Press Ctrl-T to open a new tab, which will display the Fast Dial page, where you’ll see Google home page added to one of the empty Fast Dial box

§  Right Click on the newly added Google box and select properties

§  Click on the advanced tab, that will display the dialog as shown in Fig below.
