How to configure basic passwords and a hostname on a Cisco switch


Today I will show you how to configure basic passwords and a hostname on a Cisco switch.  For this tutorial you are going to have to open up a console session to your switch.

First we need to set an enable password:

Switch>enable

Switch#configure terminal

Switch(config)#enable secret c7ed2bd92a (sets enable password)

 

Now we need to set the hostname of the switch:

Switch(config)#hostname Comtech1 (sets the switch hostname to Comtech1)

 

Next we need to configure console access:

Comtech1(config)#line console 0

Comtech1(config-line)#password bob2 (sets console password to bob2)

Comtech1(config-line)#login

Comtech1(config-line)exit

 

We will now set passwords for ssh and telent access to the switch:

Comtech1(config)#line vty 0 15

Comtech1(config-line)#password BigBlue (sets ssh and telnet password to BigBlue)

Comtech1(config-line)#login

Comtech1(config-line)#exit

Comtech1(config)#exit

For the changes to take effect we have to save them in the startup-config file so:

Comtech1#copy running-config startup-config

And that’s it.  Next time you connect to your switch either through a console, shh or telnet session you will be asked for the relevant passwords.

How to make a bootable Windows 7 USB stick


Today I will show you how to install Windows 7 without using a DVD.  Yep today we are going to make a bootable Windows 7 USB stick.  This comes in really handy when you are installing Windows 7 onto netbooks or computers that don’t have DVD drives.  It is also a lot quicker than DVD installations too!!

The first thing we need to do is download a piece of software called  Windows 7 USB/DVD download tool from the Microsoft website.  Once downloaded and installed you should get the following screenshot.

Choose the location of your ISO file and click next.  On the next screen you will be asked to choose your media type.  Pick USB device.

You will then be asked to pick your USB device and when you have done so click Begin Copying.  This installs the ISO image onto the USB stick and makes it bootable.

Going Mobile


With the onslaught of mobile computing I thought it was time to take ComTech into the fold.  The website was designed for desktop viewing and didn’t cater for smaller mobile screens.  So it was time to have a look at the available plugins for WordPress to see if anything could be done.

Enter stage left MobilePress.  This little beauty detects when your website is being viewed by a mobile device and adjusts the page accordingly.  Voila ComTech is mobile!!!

Next on the list was to sort out an App.  Most mobile users I have spoken to would rather use an app than go online and browse through a webpage.  So it was time to get one.  One big problem.  I can’t write code.  I can fix a computer, build one from scratch and sort out software and hardware issues but write code – not a chance!!

Then I came across Conduit Mobile.  Without having any programming skills you can design and publish a simple app for your business.  You can also submit it to the Android Market and App Store (you will have to pay registration fees) if you so wish.  I decided to go down the Blog feed route and the app is called ComTech News.  Hopefully this will complement the traditional blog and drive more traffic to my site.  I have already tried it on a Blackberry Bold 9780 and it works lovely (even if I do say so myself!!).

Here’s to going mobile!!!  Anyone else going to join me?

Is Microsoft Windows the only way?


Here is a thought for you. Ask your average user what is a computer and there is a good chance the answer will be Windows. You see Windows and computers have become intertwined to such an extent that the average user doesn’t know anything different. Some might know about Mac but here is another one – Linux.

Linux is open source, that is all the code is freely available to anyone who wants it. You can modify it to your hearts content but you must also make your code freely available to anyone else that wants it. This provides a vibrant community where all the best ideas get used and the poorer ones get left at the wayside.

But what about all my applications like Microsoft Office? Linux has literally thousands of applications available. If you use Microsoft Office then try Open Office or AbiWord. If you use Internet Explorer then try Firefox. You see you can accomplish almost everything on Linux that you can on Windows. I say almost everything. For instance ITunes does not work on Linux (I have never been able to get it to work but will stand corrected if someone else can).

So why should you try Linux?

1. It is free. There are no licence fees. You can install Linux as many times as you want without having to pay a fee every time.

2.No Viruses. That is not totally true. There is a miniscule amount of viruses around for Linux but nothing compared to Windows. Most viruses are written for Windows.

3. Customize. You can change almost every part the operating system to suit your own purpose (if you choose) or leave it as it is.

4. It is stable.  You will spend less time fixing your system than you will with Microsoft Windows.

5. Easy to use.  I use Linux Mint 12 which is very stable, easy to use and I would recommend it to anyone as a desktop system.

Check out www.distrowatch.com for all available downloads for Linux. So there you have it. Welcome to the world of Linux.  Why not give it a try?

6 Blackberry Apps for Kids


Ever since I got my Blackberry Playbook my daughter wanted a go.  She is very interested in touching the screen and generally playing about on it.  Bearing in mind that she is only 19 months old I had a look at what Blackberry offer in terms of apps for kids.  This is what I have found so far.

1. Kids Doodle

This is one of her favourite apps.  Everytime you touch the screen you make a line with different colours.

2. Animal Sounds

You move the screen around and press on the animals to get their sound.  Simple but really good!!

3. Drums Lite

Ever wanted to play the drums but not have the space.  You can now with Drums Lite.  You get a full drum kit so just go ahead and hit it.  My daughter really loves this!!!  You can get the paid version but it is really not worth it in my opinion when the lite does everything I need.

4. Piano

Another one of her favourites.  You get a full piano which you can hit and make as much noise as you want (see a pattern yet?).  What else does a 19 month old need?

5. Xylophone

Exactly the same as the Piano but this time with a Xylophone instead.  Again though a really good app.

6. Scratchpad

This app is not actually designed for kids.  It is designed for the business productivity market however it allows kids to draw images (or whatever they fancy).  It is basically Kids Doodle without the fancy colours.

This list is not exhaustive by any means but I hope it gives you some insight into what is available on the Blackberry platform for kids.

Setting up a VPN Server using Untangle Gateway


Today I will show you how to set up a VPN Server using Untangle Gateway.  Untangle Gateway is a dedicated hardware firewall which can be configured in a multitude of ways one of those being as a VPN server.

For the basis of this tutorial I will assume you already have Untangle Gateway installed and configured with the default rack.  If not this tutorial will show you how.

On the default rack shown above scroll down until you come to OpenVPN and click on settings.

On the following screen you will get the option of setting Untangle Gateway as either a VPN server or a VPN client.  Click on VPN server.  This opens up the wizard.  Click next.

To complete the VPN setup you have to configure 2 steps.  Step 1 is your organisation details as shown below.  Once you have entered the required details click next.

Step 2 is to configure a list of hosts or networks that your VPN users will have access to. Your internal network is added by default.  If you wish your users to be restricted to certain servers or workstations this is where you configure it.  For the purpose of this tutorial I will leave this as my internal network.

Once you are happy with the configuration click next.  You will then get the finished screen.

That is your VPN server configured.  We now have to add remote clients.  Untangle Gateway also gives you the option of adding remote networks instead of individual clients.  For the purpose of this tutorial I will add a remote client.

Close down the page to get back to the main page and click on the Clients tab.

On the next page click Add.  This is where you enter the details of the remote client.  My remote client will be called XP1 and I shall leave the Address pool as default.

Once configured click Done.  You will now see that XP1 has been added to the remote client list.

Now click Apply and when applied click ok.  Your server is now set up and XP1 should be able to access your network.

How to transfer files to your website with Filezilla


Today we are going to talk about transferring files to your website with Filezilla. Filezilla is an open source package which is freely distributed under the GNU General Public License and allows you to upload and download files from your computer to your website and vice versa.

For the basis of this tutorial I will be installing Filezilla on Linux Mint 12 but it can be installed on any Linux distribution or any version of Windows.

On your linux system open up a terminal and type:

sudo apt-get install filezilla

Enter your password when asked to do so.  Once installed open up the package and you should get the screen displayed below.

Ok lets explain the interface a bit.

Host – This is your domain name (e.g mine would be www.comtech247.net)

Username – This is the username that allows access to your website cpanel.

Password – This is the password that is associated with the cpanel username.

Port – This is the port that you want to use to connect to your website (You can usually leave this blank as Filezilla will automatically configure it for you).

Enter your details and click on Quickconnect.  Once connected you should be able to see the screenshot below.

On the left you will see the file layout on your computer.  On the right of the screen you will see the file layout of your website.  To upload a file to your website do the following:

  1. Highlight the file you want to transfer on the left side of the screen (the one you want to upload to your website).
  2. Highlight the folder on your website where you want the file to be transferred to.
  3. Right click on the file to be uploaded and click on Upload.

Thats it!  Your file will now be transferred to your website.  To download a file just reverse the steps.

How to test your Broadband speed


Today I will show you how to test your broadband speed.  BT, Virgin and the other ISP’s will sell you packages of upto 20, 30, 40 Mb but they never tell you exactly how fast your connection will be.  For that you need Speedtest.

Speedtest.net allows you to retrieve a packet of data from your nearest server and then measures how long it takes to download it (download speed) and then sends the packet back on a return journey (upload speed).

You should do the test three times to get average download and upload speeds.  Also make sure when you do the tests that you are not downloading or uploading any files as this will skew the results.

Speedtest.net also allows you to rate your ISP.  This is good because there is no better feedback than that from customers so if you think that your ISP is good or bad then rate it.  Other people will thank you for it!!

How to schedule a backup in Linux Mint 12


Today I will show you how to schedule a backup in Linux Mint 12 so that your precious data is safe.

Linux Mint 12 comes with the Backup Tool shown below which allows you to backup your data and software installed on the system but unfortunately it doesn’t allow you to schedule backups.  For that we need the cron daemon.

The cron daemon uses the crontab file  (think Task Scheduler in Windows) which allows you to set the backup schedule.  The beauty of using cron is that it works ON ALL LINUX DISTRIBUTIONS not just Linux Mint. You don’t need to install cron as it comes installed by default.

Ok time to get your hands dirty.  Open up a terminal and type “su” and when prompted enter your root password.  Next you want to open up the crontab file.

Next type “gedit /etc/crontab” in a terminal.  The crontab file should look similar to the table below.

 

M H Dom Mon Dow User Command
1 9 * * * Root Tar -cvf/media/dev/sdb/backup.tar /home

Where:

M = minutes

H = hours

Dom = every day in the month

Mon = every month

Dow = every day of week (e.g 1-5 would be Monday to Friday inclusive)

User = user who can perform this task

Command = what is getting backed up and where is it getting sent to

So in the above example I have backed up a folder called home (/home) to a folder called backup.tar which is on sdb (/dev/sdb/backup.tar) at 1 minute past 9 everyday in the month, every month.  The authorised user is root and the command to be used is tar -cvf.

When you have configured the crontab file save it and exit.  Your backup schedule is now set.

An error occured in avast! engine: Invalid argument


An error occured in avast! engine: Invalid argument.  I had the pleasure of meeting up with this error earlier this afternoon while trying to run Avast on a Linux Mint 12 system.  To fix it I did the following:

1. Unistalled Avast completely

2.In opened up my home directory and viewed the hidden files.  I then located the .Avast directory and deleted it.

3. Reinstalled Avast

I hope that this is of help to someone.
