Network Stuff – Handy network utility

Posted by brainfoldb4u on March 15, 2010

Network stuff is a cool Network Utility that comes whole set of very useful network tools like Whois, tcp/udp telnet, raw packet forger that gives more information about a host on a network and to perform simple tasks.

Network open source tool including:

  • – tcp/udp telnet
  • – ping/traceroute
  • – DNS resolver
  • – Whois
  • – Arp
  • – Stats and TCP/UDP/IP tables (iphelper functions)
  • – TCP/UDP/ICMP/CGI multithreaded scan (TCP and CGI scan could be done throw HTTP or socks proxy)
  • – Raw packet capture (multiple options including application name)
  • – Raw packet forging
  • – Wake on LAN and Remote Shutdown
  • – Interactive TCP/UDP Transparent Proxy

Its key features allows user to easily find information on a network reached through different interfaces, which are accessible through different tabs.  Information includes the hardware address being used, the IP address assigned, the link speed, link status, and vendor information on the network adapter. It also provides traffic information, including incoming and outdoing packets. While it doesn’t have advanced troubleshooting features, it does show errors in both incoming and outgoing packets, and provides a collision count. This includes information separated into TCP info, including detailed packet stats, UDP info with information about datagram like  ICMP, IGMP.  Network stuff  can also provide a routing table, with comprehensive information included. It can also show multicast data, and show the current state of all sockets the computer might have open, closed, or waiting.

Network stuff offers a number of diagnostics, including statistics and error counts, and all zones on a network. The Ping utility used by Network Utility is similar to other ping services, allowing input of a destination address, and a set number of pings to be sent. For each ping, of 64 byte packets, a transit time is given, helping troubleshoot network connections.  The Traceroute, Whois, and Finger options of the Network Utility are all analogous to those found in other operating systems. Traceroute displays the full route from the host computer to the destination, with hop times listed. Whois queries a whois service to return information on a domain name registrant. The Finger utility allows a user to look at a specific user profile on a specific server.

  • What is Interactive TCP/UDP

To  capture packets

Go to the Capture window (Tab “Raw Packet” then “Capture”).

To capture packets, you have to check protocol you want to capture.

Here we are capturing tcp and icmp packets

Next, for each protocol you can specify special filters. Another filter is available for tcp/udp connection: this is the “Application filter”

The option “Packet’s details” allow to show generally usless header fields. By checking this, all header fields are shown.

You can start/stop capture using the coresponding buttons.
The “Clear” button allows to clear the list of captured packet.
The “Load” button allows you to load a previous saved capture in txt or xml format.

Tcp filters :
– Source Ip
– Destination Ip
– Source Port
– Destination Port
– Sequence Number
– Acknowledgment Number
– Data Offset
– Window Size
– Control (URG,ACK,PSH,RST,SYN,FIN)

In this sample we are capturing only packets sent to and received from ip 10.0.0.138 port 80

How to forge packets

Go to the Forge window (Tab “Raw Packet” then “Forge”). Three different easy forging interfaces are available for tcp,udp and icmp;and another generic interface for other protocols is also available

For all protocols, you can configure all IP header fields options that means :

  • – Version
  • – IHL
  • – Precedence
  • – Delay
  • – Precedence
  • – Throughput
  • – Relibility
  • – Total Length
  • – Identification
  • – Fragment type/position/offset
  • – TTL
  • – Protocol number
  • – Checksum
  • – IP source
  • – IP dest
  • – Options

Some fields have the “Random” option which allows you to test your firewall/IDS reactions.

Notice : random fields are computed separately for each sent packet

What is the option “Auto” for length and checksum ?

If you don’t want to forge bad packets, you just check these options, so the fields are computed and you don’t need to comput them manualy.

Protocol data could be ASCII or hexa depending the “Hexa values” option

At this point you just need to specify the number of packets you want to send.

If you select the “Looping” option, packet are send until you push the “Stop” button.

Just click “Send” to begin packets sending

Web attacks are getting more frequent now a days and its very hard for an average user to identify which site is good and which site will harm his computer. Our browser of chose becomes to play a big role in protecting our computers.  Despite browsers like Firefox, Google chrome, IE, Opera and safari gives a level of protection, its still worthy to have a assurance from an independent body regarding the worthiness of the website from an  unknown source.

I came across this application/add-on from a company called Web of Trust providing a significant level of assurance regarding the website that we are visiting. Say if your web site sells something or “sign up here”button, people are in real dilemma to trust or not the web site. Instead of clicking be not being sure  now with Web of trust a website cab show  that your online business is trusted by millions of members of  Web of Trust. The WOT community has rated 26 million websites for trustworthiness, vendor reliability, privacy and child safety. Use it to your advantage!

WOT is available as an add-on for major browsers for download here (Firefox, Google Chrome, IE)

Process Explorer: Windows Task manager alternative

Posted by brainfoldb4u on March 12, 2010

Process Explorer v11.33 is a freeware from Microsoft showing information about which handles and DLLs process have opened or loaded. We all would hit Ctrl +alt+delete when PC hangs up and to kill the current process running and bring up the task manager. some power users may click CPU column twice to see which processes are sucking up most of the CPU’s power. Alternatively we may scan the process list for suspicious items. Here i saw this pretty useful tool from Microsoft simplifying task manager and even gives more granular details about a process including its icon, command line, full mage path, memory statistics, user account, security attributes and more.

Process Explorer

Process explorer showing system information details in graphical representation

Process explorer with system information

Process explorer with system information

The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you’ll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you’ll see the DLLs and memory-mapped files that the process has loaded.Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work. You can right -click and kill a process as in Task Manager, with the obligatory warning that killing a process can destabilize the system. Process Explorer’s added ability to kill a process and all of its descendant processes may forestall stability problems. Process Explorer can also suspend a process’s execution and resume it later. Say you’ve got a number-crunching utility that’s tying up the CPU and you want to stop for a minute while you check your e-mail. With Process Explorer, you can suspend the app briefly without going through the hassle of shutting it down and starting all over again after checking your mail.

Task Manager helps you figure out what program a given process represents by displaying its internal description, if available. Process Explorer goes a step farther by adding the company name. Still puzzled? Double-click the process and click the “Strings” tab in the resulting properties dialog—it lists all text strings found embedded in the process’s executable file. The properties dialog also reveals the full pathname and command-line for the process, lists and graphs performance statistics, and even displays TCP/IP activity.

Selecting the process corresponding to an on-screen window is a snap—just drag the utility’s  icon onto the window. You can also enable a lower pane that lists all DLLs used by the selected process or all handles opened by that process. And a search option makes it easy to get a list of all programs currently using a specific DLL or identify which program is holding a certain file open.

Checking brand name availability

Posted by brainfoldb4u on February 4, 2010

Its common for most of us to have a virtual name in the internet. And we tent to have that name across the internet and that becomes our  identity. There are chances that your username/virtual name/your identity may be used by some one anywhere in the internet (heavily possible).  having the same username across every website makes you to easily remember  and helps you be recognizable across multiple networks without the need to link your accounts. I started browsing to find a way to customize a brand name and check how unique it is. thank fully i  found great solutions in order to verify the availability of our username across multiple social media websites for free.

KnowEm

This is a free site allows you to check for the use of your brand, product, personal name or username instantly on over 350 popular and emerging social media websites. It lets us to secure your brand before someone else does.

With a click of a button it lets us to search for the availability of a username across more than 350 popular social networking websites. All you need to do is is enter your desired brand username in the search box and click “Check it”. KnowEm will then come up with a list of all the social media networks along with the availability of your username. If you wish to sign up simply click on “Available” to jump to the sign up page of any particular website and get registered.

KnowEm also constantly updates and adds new sites to their vast database of social sites. The next Facebook, Twitter or MySpace is already out there or could be coming soon – do you know which one it will be? KnowEm offers a subscription service (Brand Protection Program) to ensure that you and your brand will not have to worry about it. As new sites emerge we will make sure that your flag is already planted and you will not have to worry about dealing with a squatter or someone who is misrepresenting your social media identity.

Is Your Name Available?

The basic free version of KnowEm makes it easy to find out if your favorite username is still available on the 350 social media services. Just type in your favorite username and KnowEm will check if your name is still available on these sites. Given how closely our online identities are often tied to one single username, it only makes sense to claim the same username on every site and to ensure that somebody else isn’t impersonating you. Other services that offer similar free features include Namechk (148 sites) and Usernamecheck.com (68 sites).

Premium Services

The new premium services extend KnowEm’s portfolio by giving businesses additional services for claiming and monitoring their brands. For users of the Corporate Edition ($349), KnowEm will create profiles on 150 social media sites and populate them with photos, bios and descriptions. A cheaper version of this services ($99) only includes the signup process, and users will have to populate their profiles by hand. For an additional $49 per month, KnowEm will also register your name or brand on new social media services as they launch.

Namechk

Namechk is an worthy alternative to KnowEm with almost similar features. It checks for desired username or vanity URL’s that are still available at dozens of popular social networking and social bookmarking websites. It helps to promote your brand name constantly by registering a username that is still available on the majority of popular websites.

NameChk is completely free to use, it seems to be supported by Google Adsense adverts, but these are small and don’t get in the way. It’s a very useful website and a real joy to use! NameChk is perfect for anyone that struggles to find good usernames on a number of the social networking sites. It is becoming more difficult so this is a great idea. It is also good for companies who are trying to build their brand image; they can use this tool to find a name which is available on most of the platforms and then register it to promote their products.

Namechk Features

  • Check usernames on 106 different social networking sites
  • Register by clicking on the buttons
  • Find usernames which are available on all platforms
  • Build your brand image

Username check

A simple service that might nonetheless come in handy sometime, the suitably-titled UsernameCheck will let you find out where is your username registered in a more or less instant way. If you claim  “Do I have my username registered across every site that I should?”. That is a valid question, because how would you feel if the next Internet humiliation that comes along happens to share the same username that you have been using since the dawn of the web?

This site, then, will let you check where you username is registered just by supplying it and hitting the “check” button. A service by service rundown is then carried out, and you will then find out whether your back is covered or not.

Email Encryption: Lockbin

Posted by brainfoldb4u on January 21, 2010

IF you want to send an email with critical contents and needed to safeguard it from prying eyes, Lockbin would help you by using a closed system that will take any message and send it to someone in a highly secure manner. Sender needs to share a secret password to recipient while the recipient needs to remember the password to read the message.  You dont have to install any additional software, everything is done online, you just needed to be online to read the message. In the case of Gmail, and a handful of other popular Web-mail providers, your e-mail could be in a dozen different servers (albeit encrypted), or even be analyzed to try to sell you contextual ads.

In a few words, Lockbin is a free service for sending private email messages. People use it to send things like credit card information or confidential information. Secure Socket Layer is used as a secure way of sending emails from Network sniffers but there is no guarantee the recipient is taking the same precaution.

Developers claims about its safety as:

Nothing is perfect, and neither is this, but it is certainly safer than sending sensitive data directly through email. The largest threats to this method would be

1) capturing the sender or recipient’s password by spoofing the Lockbin website, or

2) a screen capture virus that images the decrypted message on the recipient’s computer.

Neither attacks are likely, but are possible in theory.

How it works:

Lockbin’s cryptographic algorithm uses a Secret Word to encrypt messages. You invent the Secret Word and deliver it to the recipient using a phone, text message, instant message, smoke signals, homing pigeon, or as a last resort… another email.

When the encrypted message is received, it is destroyed from Lockbin’s database, and decrypted in the recipient’s browser, provided that they entered the Secret Word correctly. Uncollected messages are destroyed after six months.
