Enable SSH in Switch And Router

Enable SSH in Switch And Router

Assuming the IP address, enable password and default route are in place, the additional steps needed are as follows:

1. Configure a domain name
cisco(config)# ip domain-name

2. Configure the RSA key generation for encryption
cisco(config)# crypto key generate rsa
* it may prompt user for the key length generated in the range of 360 to 2048. Default is 512-bit.

3. Configure authentication method
a) Using local database
cisco(config)# username cisco password cisco


b) Using Radius server
cisco(config)# aaa new-model
cisco(config)# aaa authentication login Radius_Server group radius
cisco(config)# radius-server host

4. Configure the terminal line
cisco(config)# line vty 0 4
cisco(config-line)# login local                                            // using local database


cisco(config-line)# login authentication Radius_Server          //using radius server

How To Run Linux Router Vyatta in GNS3

How to run Linux Router Vyatta in GNS3

What is the Vyatta ?
Vyatta is bringing innovation and affordability to the networking industry by delivering advanced routing and security in a software-based network OS that scales from the branch office to the service provider edge. Vyatta has decoupled networking software from proprietary hardware allowing users to leverage the price and performance advantages of standard x86-based hardware and components as well as Citrix XenServer and VMWare virtual or cloud environments.

In this tutorial brezular shows us how to install Vyatta 6.1 Core LiveCD on Qemu image and run it from GNS3.

1. Download Vyatta Core 6.1 LiveCD iso (You need to fill short questionnaire for Vyatta download)

Vyatta download

2. Create Qemu qcow2 image

/usr/local/bin/qemu-img create -f qcow2 ./vyatta6.1vc.img 1G

3. Boot Qemu image with Vyatta 6.1 LiveCD

 /usr/local/bin/qemu -boot d -hda ./vyatta6.1vc.img -cdrom ./vyatta-livecd_VC6.1-2010.08.20_i386.iso -m 512

login/password: vyatta/vyatta

4. Install Live CD

To install Live CD to Qemu image enter this command (as user vyatta)


The tutorial is opened and it walk you through installation process:

Would you like to continue? (Yes/No) [YES]: Enter

Partition (Auto/Union/Parted/Skip) [Auto]: Enter

Install the image on? [sda]: Enter

This will destroy all data on /dev/sda. 
Continue? (Yes/No) [No]: Yes

How big of root partition should I create? (1000MB – 1074MB) [1074]MB: Enter

I found the following configuration files 
Which one should I copy to sda? [/opt/vyatta/etc/config/config.boot] Enter

Enter password for administrator account 
Enter vyatta password: your_password 
Retype vyatta password: your_password

Which drive should GRUB modify the boot partition on? [sda]: Enter

Now you successfully install Vyatta.

5. Adapt Vyatta NIC behavior to GNS3 Qemuwrapper

GNS3 qemuwrapper always changes MAC address of presented NIC during the boot of Qemu instance. Vyatta is programmed to save MAC address of existing ethernet interfaces. If MAC address of particular NIC is changed (by GNS3 qemuwrapper) Vyatta preserves the interface with old MAC and create new interface with new MAC. 

Each time Qemu instace is restarted the number of interfaces doubled.

These are my steps how to solve it (it must be a better solution but I didn’t find any with Google search):

a) Enable root account on Vyatta 6.1

thank to Tim Peerlings blog

vyatta$ configure 
vyatta#set system login user root authentication plaintext-password test 
vayata# commit 
vyatta# save


Now you should switch to user root:

Password: test

b) Remove vyatta_net_name script (root account needed)

cd /lib/udev/ 
mv ./vyatta_net_name ./vyatta_net_name_backup 
rm ./vyatta_net_name

6. Setup serial console login 

thanks to Petr’s blog 

This configuration redirects output to serial ttyS0 and allows you to use Console in GNS3. 
Login as root with su command and modify grub configuration file:

vim /etc/default/grub

Change the lines in configuration file according to these lines
# This file is sourced by update-grub, and its variables are propagated 
# to its children in /etc/grub.d/

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` 
GRUB_CMDLINE_LINUX_DEFAULT=”console=tty0 console=ttyS0,9600n8″

# Uncomment to disable graphical terminal (grub-pc only) 
GRUB_SERIAL_COMMAND=”serial –speed=9600 –unit=0 –word=8 –parity=no –stop=1″

# Uncomment if you don’t want GRUB to pass “root=UUID=xxx” parameter to Linux 
Now update grub with command:


7. Setup GNS3 for Vyatta qemu image

- Start GNS3 
- Edit-> Preferences-> Qemu-> Qemu Host

Check Kvm option only if your processor supports hardware virtualization. Check Kqemu option only if it is installed and running. If you are not sure with these options let them unchecked otherwise Qemu will be not started.

You need also set Qemu general settings like path to qemu, qemu-img and qemuwrapper.

- Edit-> Preferences-> Qemu-> General Settings

Login to Vyatta:
login/password: vyatta/your_password

8. Conclusion
Brezular has  made a video to prove functionality of Yvatta Qemu image. In this video three Vyatta Qemu instances run RIP routing protocol.

Step 3 – Type “Y” and hit enter if you want to empty your bin too.

2. Remove Programs You Never Use
Junk program can be the reason for your slow computer, by saying “junk” I mean those programs and software you never used before. Sometimes some programs and adware software can installed automatically and starts decreasing our computers speed. By deleting these files you can easily speed up your computer.
Step 1 – Open the windows run command. You can also open it by pressing (windows key+ R).
Step 2 – Type “appwiz.cpl” and hit enter.

Step 3 – Remove the programs.
Now the window called programs and features is open, in this window you can select the programs what you’ve never used and uninstall it.

If you having problem with uninstalling a program here is link to show you “How To Remove A Program & Software Which Won’t Able To Uninstall ?”

3. Limits Startup Programs
Startup programs are those programs which starts automatically when your windows starts. You can customize your startup programs and make your windows boots up quickly.
Step 1 – Open run command.
Step 2 – Type “msconfig” and hit enter.
Step 3 – Go to the startup tab and Un-tick those programs what you’ve never want to start with your windows startup.

8. Adding more memory (RAM)
RAM is random access memory. It’s a fast version of a typical hard drive, and it’s used to store temporary information and data currently in use by your system (mainly operating system). The more RAM you have the better performance your machine gives you. You can think of RAM as tellers in a bank processing customers’ needs in real time. The more tellers you have (RAM), the faster the processing. Adding a memory is a good up gradation to speed up your computer. Here’s some links which can help’s you regarding your ram upgradation.
