Configure Telnet Remote Access


Configure Telnet Remote Access
LAB Topology 3

Lab requirements:
1. Router Name: Auzanet_Router1, Auzanet_Router2 and Auzanet_Router3
2. Set password to auzanet123, secret to auzanet123, and vty to auzanet123. All the passwords are required to be encrypted.
3. Configure all the routers.

Lab Process:
Configure Router 1
Router>en
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname Auzanet_Router1 SET ROUTER’S NAME
Auzanet_Router1(config)#enable password auzanet123 SET ROUTER PASSWORD
Auzanet_Router1(config)#enable secret auzanet123 SET ROUTER ENCRYPTION PASSWORD
Auzanet_Router1(config)#line vty 0 4 ENABLE TELNET
Auzanet_Router1(config-line)#password auzanet123 REQUIRE PASSWORD AUTHENTICATION
Auzanet_Router1(config-line)#login
Auzanet_Router1(config-line)#exit
Auzanet_Router1(config)#service password-encryption SET GLOBAL PASSWORD ENCRYPTION
Auzanet_Router1(config)#interface serial 0/0/0 ENABLING THE SERIAL PORT
Auzanet_Router1(config-if)#ip address 10.10.2.1 255.255.255.252 SET IP ADDRESS OF THE SERIAL PORT
Auzanet_Router1 (config-if)#clock rate 64000 CONFIGURE CLOCK RATE IF SERIAL PORT IS DCE
Auzanet_Router1(config-if)#description ***Connected to Auzanet_Router1*** SET PORT DESCRIPTION
Auzanet_Router1 (config-if)#no shutdown ACTIVATE THE INTERFACE

Configure Router 2 and Router 3 the similar way the Router 1 is configured. The IP addresses of the interfaces are different. Set the clock rate of the DCE end on every WAN link.

Commands for Telneting from Auzanet_Router1 to Auzanet_Router2:
Auzanet_Router1#telnet 10.10.2.2
Trying 10.10.2.2 …open

Linux Hangout: The Free software revolution

We spent the whole morning on studying the installation of Fedora 16, Fedora KDE, and Ubuntu 13. We also tried to Network the games found in the Games Spin of Fedora. Unfortunately, we were not able to successfully install the network of the two computers as we were having problem on the installation of Linux on PC1 (computer with older version of motherboard and supports only IDE connection) the previous day.
We also tried to connect to the network via WiFi connection and providentially, it did work. We were able to connect to the internet and access our files at http://www.000webhost.com (host server of our website).
I learnt that LiveUSB can be a very valuable storage for installer of operating system. Gone are those days of wasting so much CDs and DVDs for installers.
The advancement of the technology has led us to the successful use of USB drive as storage for the Installer of Operating Systems and Operating System itself.

Play with Fedora Today!

Day fifth of the training and the excitement was still boosting from within. This feeling was stress with the interest as to the installation of the Fedora Games spin. Although, I’m not really a gamer, I was eager to know the inside of the OS.
The Fedora Games spin is a customized OS which was built just for you and me. The spin offers the best games that can be found in Fedora. The games found extend to several genera from just ok-ok games to real-time and turn-based strategy games, mind-boggling games, tricks and mind-puzzle games. Armacycles is one of the best games that can be found in the spin. Taken from the movie Tron Legacy, it is a very tricky game which involves high analytical schemes in order to win. These different games can also be played via network where other players can actively play according to their strategic efforts and willingness to win. Trying this spin will surely give you a reasonable impression that Fedora can run variety of great games.
This spin includes a number of popular games including:


Aside from installing the Spin of Fedora, we also tried to install the KDE Spin. This spin was more advance and its display was very appealing to the end user.
The KDE Spin can easily connect to the internet and almost all office applications are package in the installer.
Conversely, we also met problems in the installation, like how to create different partitions. So, I download the Fedora-15-Installation_Guide-en-US.pdf to have a better understanding in the process.

Installation of Different Spins for Fedora

The continuation of installation of different spins for Fedora

We spent the whole morning experimenting on the installation and exploring the different Spins of Fedora that we installed in the desktop computer. We tried installing the Design Suite Spin, Plasma Desktop Spin, LXDE Spin, and XFCE Spin. We have tried installing the Spins in the computer with latest version of motherboard or that which supports SATA connection. However, we had difficulty in installing it to computer with earlier version of motherboard or that which supports IDE connections. We theorized that the problem was in the connection (SATA and IDE), because, although we have tried to upgrade the capacity of the RAM to meet the minimum graphical requirement of the latter, the system still didn’t work. 

The Manager of the company gave us an assignment to study at home before engaging to the networking of the computer with Linux Operating System. And these were the following: ClearOS, Zero Shell, PF Sense, Monowall, Proxy: Squid Cache, DNS Cache, and Telephony: Asterisk (Asterisk Now, ASTLinus), VoIP.

Error in boot using USB drive for Fedora?

Error in boot using USB drive for Fedora?
Or can you see something like this:
[16.467025] USB 1-2: device not accepting address 2, error – 110
[32.103021] USB 1-2: device not accepting address 2, error – 110
[42.627052] USSB 1-2: device not accepting address 4, error – 110
[47.2221531] [drm] nonveau 0000:02:00.0: Register 0X00004030 not found in PLL limits table

Solution:
  1. Go to ‘BIOS Setup’ by pressing DEL, F4 or F2 (Depending on the motherboard of your computer)
  2. ‘Advance Bios Features’
  3. Check if there is ‘Installer OS Select – Auto’
  4. Change ‘Auto’ to ‘Others’
  5. Save Changes by pressing F10.
  6. Then reboot your system and use your computer's built-in function to choose the USB boot device -- usually this is a special key you hold down at boot time, such as F12 or F9. Then enjoy!


This little knowledge we uncover thru contributed efforts was made possible with the help extended to us by the manager of Auza.Net.
How to create a bootable USB/flash drive for Fedora?
The process for most people is simple. Almost all USB sticks are provided by hardware manufacturers ready to use with this process. If you have any documents on your USB stick, it's not a bad idea to back them up before you start.
Then reboot your system and use your computer's built-in function to choose the USB boot device -- usually this is a special key you hold down at boot time, such as F12 or F9. Then enjoy!
If you have problems in booting thru the use of your USB, go to BIOS setup. Change the boot sequence. Set the boot device priority as your USB. Then also check “Advance BIOS Features”. Change “Select Operating System” from “Auto” to “Other”.
