How to get 25GB online cloud storage for free

(Posted On August 3, 2011 by cyphernetic)

There are several free online cloud storage which offers sharing and assign permission for folders for private or public but with Windows Live SkyDrive, you can avail of free online storage for 25GB at most. SkyDrive also offers its users to create Word, Excel, PowerPoint documents, without having Microsoft Office installed.

One thing that interests me is the drag, drop and upload feature which simplifies the backup process. Since SkyDrive is a cloud online storage, you don’t need to be on your computer to access your files, instead, you’ll only need to be with any computer with internet or even with mobile devices like phone that can access the internet.

Cisco Router Sub-Configuration Mode

(Posted On June 17, 2011 by cyphernetic)

The configuration access mode contains two different levels:

Global Configuration mode
Sub-configuration mode

At the Sub-configuration mode, the commands that are entered affect only specific component of the device.

The following are the different sub-configuration modes and their corresponding prompts

Mode	prompt
Interface Subconfiguration mode	(config-if)#
Subinterface Subconfiguration mode	(config-subif)#
Line Subconfiguration mode	(config-line)#
Controller Subconfiguration mode	(config-controller)#
IP Routing Protocol Subconfiguration mode	(config-router)#

To return to global configuration mode, type exit from the sub-configuration mode.

How to lock folder without using software

(Posted On June 15, 2011 by cyphernetic)

The lock folder method might also be called as folder cloacking where a folder is renamed to a known Windows Class Identifier (CLSID) to redirect to a different special folder upon opening. This method can be executed in a single cmd command only.

Steps to execute to lock your folder.

1. Your folder resides in Drive E labeled as myfolder (Your folder may be in different location and your folder may be with different name. It is important that you know where your folder reside to continue with step 2).

2. Open a command prompt by going to Start>All Programs>Accessories>Command Prompt

or simply press Win+R to open Run and type cmd.

3. Change to folders location. With this example type E: to change prompt to folders current location.

4. Rename the folder by issuing a ren foldername foldername.CLSID. With this example, ren myfolder myfolder.{645ff040-5081-101b-9f08-00aa002f954e}

5. The folder will change to recycle bin. Read More →

Dealing with Cisco Router Modes

(Posted On June 9, 2011 by cyphernetic)

There are 3 router modes available to cisco routers. These modes can be accessed via Command Line Interface or commonly known as CLI which is also known as EXEC. Therefore, 3 router modes is also the 3 exec modes which has its own different levels of access to Cisco IOS Commands.

User Exec Mode – This is also known as Privilege Level 1. By default configuration of router, this mode grants user to have access to some information about the router, viewing the status of the routing table as well as the status of the interfaces within. However, you cannot make any changes and or view the running configuration file. The prompt for this level is Router>, where Router is the name of the device.
User Privilege Mode – This mode is also known as Privilege Level 15. This level is somewhat similar to the administrator privilege in Windows operating systems and root in Linux. By typing enable in User Exec Mode, the user is taken into a higher privilege which is privilege 15 by default. This provides a high-level management access to the IOS, where User EXEC mode command can also be used. The prompt for this level is Router#, sending disable command will eventually set a lower privilege level of 1 which is the User Exec Mode.
Configuration Mode – This mode gives you total access to configuration commands that affect the entire system. There are several source of configuration commands like terminal, memory and network. User in Privilege Exec Mode can enter within configuration mode by switching to terminal using “configure terminal” command or “config term” as well as “conf t”. The prompt for this mode is Router(config)#, hitting Ctrl+Z enables user to go back to Privilege Exec Mode. Read More →

Cisco IOS Boot-up Sequence Explained

(Posted On June 5, 2011 by cyphernetic)

The operating system used by Cisco routers is called the Internetwork Operating System most commonly known as IOS. Depending on the type and model of a router, a specified IOS image can only be installed.

It is very difficult to understand the output produced by a cisco router during an IOS boot-up sequence. With this, I will enumerate and discuss each line.

System Bootstrap, Version 12.1(3r)T2, RELEASE SOFTWARE (fc1)

Cisco 1841 (revision 5.0) with 114688K/16384K bytes of memory.

This two lines state the version of the system bootstrap (like bios), hardware model and memory capacity of the device. This performs the POST (Power on Self Test). And execute the bootstrap loader from the ROM.

Self decompressing the image :########################################################################## [OK]

At this stage the bootstrap locates the IOS image from the FLASH and load the operating system.

How to Connect a Router to a Computer

(Posted On May 30, 2011 by cyphernetic)

Cisco Router Console Port

Depending on the type of router, a console port may be found either on the front or on the back. “Console Port” is sometimes referred to as “Management Port”. The port looks like a regular Ethernet port which uses RJ-45 connector, however, Console Port is far different from it. The Console Port is used using a Console Cable which allows you to configure a router from a PC. A console cable is usually shipped with router. A color blue cable with RJ-45 connector on one end and a db9 female serial connector on the other end. The serial connector should be plugged in to serial port and the RJ-45 connector is in console port.

LAN Ethernet Ports

Routers specifically made by cisco is modular. Meaning, modular cards can be attached unto it. You can add more modules for more ports. Lan ports are usually labeled as FE0, FE1, FE2, FE3. LAN Ethernet Ports are used for workstations and networking switches. These ports can also be configured for Virtual LAN.

WAN Ethernet Ports

With this ports, broadband devices like Dsl Modem or Cable Modem can be connected. Ports are identified as interface for CISCO. Wan ports are labeled as Interface E1 or Interface FA4. Read More →

Understanding Cisco Routers

(Posted On May 9, 2011 by cyphernetic)

A router is an electronic device that has similar components in terms of hardware and software with that of computers at home and office.

Some of the components found inside a router are the following:

ROM
CPU
RAM
Operating System

The main function of a router is to connect multiple networks which means that routers has multiple interfaces the each belongs to a different network. A router is an intelligent device that evaluates the packet (data that travels within routers) and decides where to forward and what network it should belong.

For every network, a separate interface must be configured to a router. If configured properly, routers can be used to connect Local Area Networks (LAN), Wide Area Networks (WAN) or both. Read More →

How to build an input/output ISA expansion card

(Posted On March 13, 2011 by cyphernetic)

There are several ways on how to build and develop an input-output isa card. This tutorial merely focus on the steps on how to develop an electronic circuit layout into the presensitized printed circuit board (a factory prepared PCB surface coated with a photo sensitive emulsion). Assuming that the circuit schematic and pcb layout is already available. If for instance you don’t have the knowledge and the basics of building a circuit, please take some time to know the steps on how to build a circuit for an input-output isa card. Read More →
