Computer Port list

What is Computer port ?

An interface on a computer to which you can connect a device. Personal computers have various types of ports. Internally, there are several ports for connecting disk drives, display screens, and keyboards.

Externally, personal computers have ports for connecting modems, printers, mice, and other peripheral devices.

Almost all personal computers come with a serial RS-232C port or RS-422 port for connecting a modem or mouse and a parallel port for connecting a printer.


On PCs, the parallel port is a Centronics interface that uses a 25-pin connector. SCSI (Small Computer System Interface) ports support higher transmission speeds than do conventional ports and enable you to attach up to seven devices to the same port.

In TCP/IP and UDP networks, an endpoint to a logical connection. The port number identifies what type of port it is.

For Network administrator must know about the computer Port, to identify network attack and network function purposed.

ROUTER Configuration (part: III end)


Cisco Basic Router

The basic component of cisco is :

1. Processor

2. Memory :
* Read only Memory (ROM) : This is like a rom at the pc, got standard program inside the rom and will run on booting process.
* Flash memory : Keeping Operation system of the Cisco called IOS
* Random access memory (RAM) : Using for buffering, storage and others.
* Non volatile RAM (NVRAM) : Keeping configuration from IOS when Cisco boot.

3. Interface :
The interface of cisco router is :





interface using format name dan number on IOS, The number started from zero (0). But the assigning the number belong to the type of the router. For the Cisco Router the interface modul is fixed:



For the Cisco Router 7500 series with versatile Interface processor, where is the modul got ethernet slot, the assigning system more specific and be carefully. Ethernet4/0/1 means port number 2 at 1st adapter in slot 4.



Console Console

Cisco Router have console port at behind the hadware. This port console be function for direct communication access into the Cisco router. The standard console port using serial asynchronous EIA/TIA-232, the others name is RS-232.

For the console port connector belong to the router type. For the Low end to middle router, using RJ45 connector, for the other Routers class using DB25 connector.

Auxiliary port

Cisco router have auxiliary port. port auxiliary using standard serial connection same with console port using serial asynchronous EIA/TIA-232 direct connection to Cisco router. Port auxiliary also for alternative access to the cisco router via modem, Administrator can used this serial when the network path from the router got problem.

Configuration File
Two type IOS configuration:
1. Existing configuration from the RAM
2. Startup configuration under NVRAM

We can change the configuration even the IOS active or running. The changes effected directly, but don't forget must save to NVRAM as startup once we changes the configure under running system.

Configure Cisco Router under PC

To configure Cisco Router from PC, need software communication called Emulation software terminal. This software function is sended the command into Cisco router. This software is has been installed included your Windows system.



Next step you have to setup the emulation software setting.

9600 baud
8 data bits
No parity
1 stop bit
No flow control

You can also connect to the router using telnet, but you must set the router IP first.

Router command mode:
This is some command of Cisco.



Started to setup new cisco:

To start configuration of Cisco, we must go under configure command.
The step to configure using the emulation software connected with console port of Cisco router is:

When the router boot up, Generally will be shown and asked you to confirm. Answer with : No

Would you like to enter the initial configuration dialog [yes] : no
.
.
router>


Router prompt default is router> called user EXEC mode. Mode router>

router> We can changes display like dos command.

Router>
1600>
1700>


Under User EXEC mode can see all the command with type ?

router> ?


To let you know the syntax type:

Router> ?
Router> show ?
Router>show conf?


Access the mode must know the to enter the configure command:

1700> enable
password: ******
router #


For configure :

Router# configure terminal
Router (config) #

Once you changes the configure, save the configuration into NVRAM:

Router# copy running-config startup-config
Building configuration . . .


Save result:

[OK]
router#


The next step for configuration is:
• Global parameter configuration
• Security Configuration
• Fast ethernet interface configuration
• Serial interface configuration
• Dynamic routing configuration
• Command-line access to the router

Global parameter configuration:

To start router configuration, we must set configure with – enable :

Router> enable
Router #


Step to configure global parameter router :



Security configuration setting,



INTERFACE FAST ETHERNET configuration

See the router prompt . . . has been changes with above



Serial INTERFACE setting



Dynamic routing parameter setting



COMMAND-LINE access configuration



To save all configuration :

1700# writ3e memory

To check configuration status:

stc# show interface ser0
Serial0 is up, line protocol is up
Hardware is PowerQUICC Serial
Description: leased line to headquarters
Interface is unnumbered. Using address of FastEthernet0 (192.168.20.1)
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, rely 255/255, load 1/255
Encapsulation PPP, loopback not set, keepalive set (10 sec)
LCP Closed
.
.
.


make sure serial and protocol line is up.

We do the same setting in LTX side. The different is only on the router IP, we assign LTX IP : 192.168.10.1
Assign the ip for each modem before Router check with your provider.

LTX access internet must route to STC network, because direct access into Internet from STC network.

This is only basic to connect between different network, for security firewall must set into the router.

Cisco router 805 specification


We used this router since 2002 until now.

Cisco 805 Series Serial Router

The Cisco 805 Serial Router offers enhanced network security and reliability through the power of Cisco IOS® Software technology tailored for small offices.









Figure 1

The Cisco 805 Serial Router gives small offices enhanced security, superior reliability, and safe investment with low cost of ownership.

The Cisco 805 Serial Router extends the power of Cisco IOS Software technology to small offices. Cisco IOS Software offers enhanced security, reliability, and safe investment, combined with low cost of ownership, to enable customers to benefit from increased productivity, simplified communication, and reduced costs (Figure 1). The Cisco 805 Serial Router enables customers to benefit from value-added services such as managed network services, virtual private networks (VPNs), point-of-sale (POS) applications, and secure Internet access.

Benefits of Using Cisco 805 Serial Router

Taking advantage of its expertise and leadership in Internet solutions, Cisco Systems offers solutions for small-office routing solutions that provide secure and reliable access to the Internet or corporate networks.

Enhanced Security

The Cisco 805 Serial Router has enhanced security features such as an integrated stateful firewall and IP Security (IPSec) encryption to enable VPNs. These features allow small offices and telecommuters to conduct business over the Internet while protecting valuable resources.

Superior Reliability

Because the Cisco 805 Serial Router is based on the same proven Cisco IOS Software technology used throughout the Internet, small offices can depend on it just as enterprise customers take advantage of Cisco reliability. In addition, a Cisco 805 Serial Router provides Internet access to multiple users without being tied to a server or dedicated PC. This means if a server on the LAN crashes, other users remain connected to the Internet.

Safe Investment and Low Cost of Ownership

The Cisco 805 Serial Router offers memory options that can be upgraded in the field so the latest networking features can be added when necessary. With an advanced processor and memory architecture, they can support future applications as customer networking needs expand. Table 1 provides a summary of Cisco 805 Serial Router hardware features.

Product Features

Security

To take advantage of the unprecedented opportunities offered by communications and commerce over the Internet, companies need to secure private information. Cisco Secure Integrated Software provides many technologies to build a custom security solution. The elements of security services include perimeter security, identity, monitoring, privacy, firewalls, IPSec encryption, and VPNs.

Standard Security

Perimeter security refers to the control of traffic entry and exit between network boundaries, such as between private networks, intranets, extranets, or the Internet. Cisco IOS Software perimeter security technologies provide a highly flexible, superior solution with features such as:

•Standard and extended access control lists (ACLs)

•Lock and key (dynamic ACLs)

•Router and route authentication, authorization, and accounting (AAA) protocols such as Password Authentication Protocol (PAP) or Challenge Handshake Authentication Protocol (CHAP), and MS-CHAP

•Network Address Translation (NAT) (including multi-NAT)

•Token card authentication with Cisco Secure authentication

NAT eliminates the need to re-address all hosts with existing private network addresses and hides internal addresses from public view. For businesses that want to allow selected access to the network, NAT can be configured to allow only certain types of data requests such as Web browsing, e-mail, or file transfers.

Enhanced Security

Dynamic firewall—Companies increasingly rely on internal networks and servers to access company data. To use the Internet as a key business tool, companies must connect their internal networks to the Internet, while keeping sensitive internal data secure. Company data can be protected against unauthorized access with stateful firewalls. The integrated Cisco IOS Firewall Feature Set is a stateful firewall that provides:

–Stateful (dynamic) ACLs (application or context based)

–Java blocking

–Denial-of-service attack detection and prevention

–Real-time alerts and audit trails

Dynamic firewalls provide these vital enhanced security features. The term firewall is used by many vendors, but not uniformly referred to as stateful firewalls. Firewalls that are not dynamic do not provide these enhanced security features.

Encryption and Tunneling

The Cisco 805 Serial Router provides IPSec encryption technology to enable small offices and telecommuters to deploy VPNs. IPSec encryption provides privacy, integrity, and authenticity for transmission of sensitive information over the Internet. The unique end-to-end Cisco offering allows customers to implement IPSec encryption transparently into the network without affecting individual PCs. The Cisco 805 Serial Router with IPSec encryption allows significant cost savings by using the Internet to create secure connections between small offices and teleworkers. As a component of the Cisco VPN solution, the Cisco 805 Serial Router supports:

•IPSec tunneling with 128- or 56-bit Data Encryption Standard (DES or Triple DES [3DES])

•Layer 2 Tunneling Protocol (L2TP)

•Generic routing encapsulation (GRE)

Manageability

The Cisco 805 Serial Router supports management by a wide range of platforms and applications. Cisco ConfigMaker (Microsoft) and CiscoView (UNIX) applications provide superior capabilities for configuration and security management, as well as performance and fault monitoring. The Cisco 805 Serial Router supports centralized administration and management using Simple Network Management Protocol (SNMP), Telnet, or local management through the router console port.

Safe Investment

Small offices with limited time, money, and staff need to know their technology investments are safe. Field-expandable DRAM and Flash memory allow small offices to take advantage of new Cisco IOS Software feature enhancements. And because the Cisco 805 Serial Router incorporates an advanced processor and memory architecture, it can support future applications as customer networking needs expand.

Companies using the Cisco 805 Serial Router can take advantage of Cisco industry-leading support options that help to ensure the router stays up and running. These support services include:

•Cisco IOS Software updates in features such as protocol, security, and bandwidth

•Full access to Cisco.com for technical assistance and product information

•Twenty-four-hour access to the industry's largest dedicated technical support staff, with the first 90 days included at no charge

Installation and Configuration Tools

The Cisco 805 Serial Router also supports configuration with the Cisco ConfigMaker application. Cisco ConfigMaker is a software tool designed to configure a small network of Cisco routers, switches, hubs, and other network devices from a single PC using Windows 95, 98, 2000, or NT 4.0. It is designed for resellers and network administrators of small and medium-sized businesses that are proficient in LAN and WAN fundamentals and basic network design.

For additional setup ease, the Cisco 805 Serial Router has color-coded ports and cables to help users make proper connections.
