In my previous posts I have shown you how to install TrueCrypt, How to encrypt an entire USB memory stick and how to use the USB memory stick once it has been encrypted.

Today I am going to demonstrate how to encrypt a single file or folder on your PC or USB memory stick by creating a TrueCrypt volume.

HOW TO ENCRYPT FILES AND FOLDERS USING TRUECRYPT ENCRYPTION SOFTWARE

In my example I will be creating a TrueCrypt volume on a USB memory stick that will hold files and folders. Once the memory stick is removed from the PC, the truecrypt volume file will be visible but the contents i.e. your files and folders will be inaccessible unless you know the password. So here is how it’s done…

Step 1 – Insert your memory stick. For this tutorial I used a 1 GB USB memory stick called ‘Aaron USB’.

Step 2 – Open the TrueCrypt software. Go to Start > programs> TrueCrypt> TrueCrypt.

Click ‘Create volume’

Step 3 – Create file container

With ‘Create an encrypted file container’ selected, Click ‘Next’.

Step 4 – Choose volume type

Step 5 – Choose volume location

Choose ‘Select Device’.

Browse to the USB pen drive (or file location on your PC) where the encrypted volume will reside. Add a filename for your volume. I have chosen to use ‘My TrueCrypt volume’.

Click save.

You will now see the path in the ‘Volume location window’. Click Next.

Select your encryption option. Click Next.

Choose the size of your volume. As I am placing the encrypted volume on a 1 GB memory stick so I have chosen to make the size of the volume 800 MB.

Step 6 – Choose and confirm your password

Click Next. If your password is not particularly strong you will receive the following warning :

Click ‘Yes’

Step 7 – Begin format process.

 Click the ‘Format’ button to begin encrypting your USB memory stick volume.

Step 8 – Exit the Wizard

Click Exit

The volume on your USB memory stick has been created.

ACCESSING THE VOLUME

Step 1 – Open the TrueCrypt software. Go to Start > programs> TrueCrypt> TrueCrypt.

Step 2 – Browse to TrueCrypt volume location.

‘Select file’ and browse to your TrueCrypt volume on your PC or USB memory stick.

Click open.

Select one of the free drive letters from the top half of the Truecrypt window and Click ‘Mount’.

Step 3 – Enter password

Enter your password and Click OK.

You will see from the top section of the TrueCrypt window that your volume has been mounted and is ready to use.

Step 4 – Navigate to your list of drives. In Windows XP this will be ‘My computer’ and for Vista/Win7 it will be ‘Computer’.

The ‘Local Disk (K:)’  icon will now appear.

Double click the icon and you will be able to access all of your files.

Step 5 – Encrypt drive after use

To Encrypt/Lock the USB drive once you are finished. Go back to the TrueCrypt interface and select ‘Dismount’

Let’s assume TrueCrypt has been installed, You have completed the encryption process and you now want to use the drive. In my example I have a 1 GB memory stick called ‘Aaron USB’ which shows up in My Computer as ‘Aaron USB (F:)’.  When you click on an TrueCrypt encrypted drive in Windows you will get the following message.

When you receive this you will need to click ‘No’ to cancel the warning as you will access your encrypted drive via the TrueCrypt software.

Step 1 - Open the TrueCrypt Software. Go to Start > programs> TrueCrypt> TrueCrypt and click the ‘Select Device’ button.

Step 2 – Select the USB memory stick. In my example it is showing as drive F.

Step 3 – Highlight a drive letter. Select one of the free drive letters from the list. This where TrueCrypt will mount your drive so you can access your files.

Click ‘Mount’

Step 4 – Enter password. This is the password you would have created when you were going through the encryption process. See encryption process here.

Click OK and you will see that the USB memory stick appears in the main TrueCrypt window.

Step 5 – Navigate to your list of drives. In Windows XP this will be ‘My computer’ and for Vista/Win7 it will be ‘Computer’.

The ‘Local Disk (K:)’  icon will now appear.

Double click the icon and you will be able to access all of your files.

To Encrypt/Lock the USB drive once you are finished. Go back to the TrueCrypt interface and select ‘Dismount’

Your files will now be protected again.

“Windows could not finish repairing the problem because the following action cannot be completed : Clearing NetBT, For assistance, contact the person who manages your network.”

This message may be produced by different faults, so it will be a case of trying a few fixes until you find the one that works. I posted the fixes below on a technical blog  I was writing for at the time and the feedback confirmed that they resolved most issues.

Hopefully, they will work for you too.

Solution 1 :  Check the PC for any Viruses or Malware. 

This kind of network problem can be caused by malicious software that has infected the computer and made changes to important registry settings. Therefore, the first step is to run full scans with your Anti-virus and Anti-Malware software
Once you are confident that the PC is clear of malicious software move onto the next step.

Solution 2 : TCP/IP stack repair method

Start, Run, CMD to open a command prompt.
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
Reset TCP/IP stack to installation defaults. netsh int ip reset [log_file_name – this can be any name]
Note: the log_file_name needs to be specified, e.g. netsh int ip reset reset.log

Solution 3 : WinSock XP Fix

This is a free software utility that has been created to fix this type of problem.
Official description – “WinSock XP Fix offers a last resort if your Internet connectivity has been corrupted due to invalid or removed registry entries. It can often cure the problem of lost connections after the removal of Adware components or improper uninstall of firewall applications or other tools that modify the XP network and Winsock settings.”
Download it here

Solution 4 : Uninstall and re-install the network drivers

· Make sure you know what network adapter you have on the PC or laptop and have the driver disk handy. If you do not have a driver disk then download the driver from the internet on a different machine and place it on USB drive to transfer to the problem PC.
· Right click My computer, Properties, Hardware tab, Device Manager
· Find network adapters on the list, expand it out to show your current adapter
· Right click the adapter select ‘Uninstall’ and confirm.
· It should now show as a problem item in your Device Manager list
· Go to the file you have on your disk or USB pen drive and re-install the network driver.

However, I appreciate this may sound quite complicated for the uninitiated. So for those that are unsure what this means let me run you through a couple of scenarios.

Scenarios

1. You’re working on your laptop when the broadband connection goes down in your house. You have the ability to browse the net on your phone but your laptop has been rendered useless as your broadband router is no longer providing the internet. What do you do ?.

2. You are out with a friend or colleague and you both want the ability to look for things online. You are fine because you have your phone but they only have the ability to use WiFi on their device and you are nowhere near a hotspot. What do you do ?.

That’s right. You turn your Android mobile phone into a hotspot and allow devices to connect it and benefit from your data connection.

So how do I do it ?

1. On your mobile phone go to Settings > Wireless & Networks >Portable Wi-Fi hotspot settings.

2. You will see the above image on the next screen. Click OK

3 .  The configuration screen will now show these options.

Router name : This can be any name of your choice.
Security : None, WEP (128), WPA (TKIP) & WPA2 (AES). Choose at least WPA.
Password (8-63 ASCII Characters) :  Choose a password of at least 8 characters. The more complex the better.

4. Put a tick in the ‘Portable WiFi hotspot – Press to turn on’ option at the top of the screen or go to ‘Settings > Wireless & Networks >Portable Wi-Fi hotspot’.

5. Your WiFi hotspot is now available.

6. On another device, scan for wireless networks and select your newly created access point (Which will be the router name you created in Step 3).

7. Enter the password and you will be able to browse the net via your phone’s data plan.

However, once you have created the page you will notice that it includes a ‘Leave a reply’ box for your website visitors. Although, you would want this feature for a blog post you wouldn’t necessarily want this option on a Bio or contact page.

So here is how you remove it.

Remove comment box from a WordPress page

1. Go to your wordpress Admin Dashboard and go to pages > All pages

2. Find the page you want to edit. In my example I have called it ‘Test page’.

3. Highlight it and select the ‘Quick Edit option’. See above

4. Untick the ‘Allow comments‘ box.

5. Navigate back to your page and you will see the ‘Leave a reply’ box is no longer showing.

I recently worked on a HP DL380 which suddenly decided to reboot itself in the middle of the working day. It was a fairly important server so the troubleshooting process got under way fairly quickly !.

The server demonstrated the following behaviour :

- Server would keep rebooting constantly
- Server would boot into Windows, run for a random amount of time and then reboot itself
- HP Smart Start disk would not run when the disk was loaded into the server
- Event logs would show the reboot but no details regarding the fault
- Server would ‘lock up’  in Windows and would need to be restarted with the power button
- Fix boot commands could not be executed

Troubleshooting

After a while the server would not boot into Windows at all which pointed toward the hardware being the problem.

The first step was to ‘re-seat’ all of the hardware components in the server and try to boot. This failed so the disks were re-seated/replaced and the memory modules were swapped out and added one by one. The final checks were the power supplies but these were fully operational so the problem had to be the main board.

This was proven to be true when the main board was replaced, given a BIOS update and the server worked as if nothing  had happened.

It is a great application that does the job well but it does have a slight issue when it comes to the default signature setting.

If you install the application, add an email account and send an email, K9 mail will automatically place an email signature (or footer) on your email which says :

“Sent from my Android phone with K-9 Mail. Please excuse my brevity.”

You may want to customise your signature or just remove the “Sent from my Android phone with K-9 Mail. Please excuse my brevity” text. So here is how you do it…..

Remove or customise the K9 Mail signature

1. Open the K9 application on your Android device.
2. Choose an account and go to Settings >Account Settings > Sending mail > Composition defaults.
3. You will see ”Sent from my Android phone with K-9 Mail. Please excuse my brevity.” in the ‘Signature’ box.
4. Untick the signature box to remove all the text or edit the signature with your own text.

They had two DMZs (Demilitarised Zones) in their network namely Internal and Public and they wanted to protect all computers and servers within these zones.

Despite a succesful installation of the Symantec client software on the webserver in the Public DMZ, they were unable to get the client to update it’s policies from the server software contained in the Internal network. I was able to verify this by going to :

1.Symantec Icon in the system tray>Right click>Open Symantec Endpoint Protection
2. Help and Support>Troubleshooting>Management Tab

In the General Information section the ‘Server’ item was showing as ‘Offline’ instead of a machine name or IP address.

It seemed clear from the above that there was a lack of communication between the client and server software which was likely to be caused by the DMZs, or more specifically the firewall rules which govern the DMZs.

Port 8014

On further investigation I discovered that Symantec uses ‘TCP 8014′ to communicate for policy updates and this was locked down on the firewall. Therefore, to resolve the issue all you need to do is allow this in your firewall rule and do the following :

1.Symantec Icon in the system tray>Right click>Open Symantec Endpoint Protection
2. Help and Support>Troubleshooting>Management Tab
3. Under the ‘Policy Profile’ section click on ‘Update.
4. The ‘Server’ item will now change from ‘Offline’ to the machine name of the SEP server or IP address.

After 10-15 minutes the client software will update itself.
