Miscellaneous / This network is blocking encrypted DNS traffic
« on: November 01, 2021, 11:40:11 am »
You may get this on iPad, iPhone or Android.

Solution - Delete your current wifi connection and then recreate it.

Miscellaneous / Nuisance calls from 08456021111
« on: October 28, 2021, 10:02:12 pm »
We have started getting these.

It's BT. Text to speech convertor. Someone sends a text to your phone and this converts it to speech.

It can be a real nuisance and it can be spoofed. Call 0800-5875252 to stop it.

Miscellaneous / Let's Encrypt web site security cert warning
« on: October 25, 2021, 09:02:12 am »
The root certificate that Let's Encrypt use for the certification path recently expired, meaning that security certificates that were issued using this are now displaying security warnings.

The answer is to force the renewal of the site certificate manually to use the new root certificate.

In a Linux terminal Window type -

certbot certificates

This will show the sites connected with the certificate.

Then try -

sudo certbot renew --force-renewal

or if you have one site -

sudo certbot certonly --force-renew --cert-name sitename.com

or more than one site -

sudo certbot certonly --force-renew -d sitename1.com -d sitename2.com

This should fix the issue.

Raspberry Pi / Some index files failed to download
« on: October 19, 2021, 09:35:10 pm »
You get this message when performing apt-get update

1. Look in /etc/resolv.conf using nano

Add nameserver 1.1.1.1 to the bottom of the list

2. Look in /etc/apt/sources.list

Alter mirrordirector.raspbian.org to legacy.raspbian.org

Raspberry Pi / Booting Pi 3B from SSD
« on: October 14, 2021, 09:23:13 am »
I found a lot of instructions on the internet about how to do this but many were incomplete or were simply just wrong.

The only way I got it to work was to add these lines to config.txt on the existing SD Card :-

program_usb_boot_mode=1
program_usb_boot_timeout=1

Then reboot. This tells the Pi to check for other boot devices.

Once done, in terminal type vcgencmd otp_dump | grep 17:

The output should say 17:3020000a where the 3 indicates that USB boot is enabled.

Now plug the SSD into a computer and using the Raspberry Pi Imager create a new image on it.

Plug the SSD in and remove the SD card. Reboot. It should now work.

I tried to use the SD card copier to copy the SD card image onto the SSD and it didn't work. I kept getting 'Kernel panic-not syncing: VFS: unable to mount root fs on unknown-block(179,2)'

Apparently if you have a Pi 3 (not the B) then you need to format a SD card and just put the file bootcode.bin onto it (available from Pi site). Then put this card in the SD card slot. This tells the Pi to boot from the SSD.

"Application has failed to start because its side-by-side configuration is incorrect".

This has loomed up following a recent Windows update.

If you download a program from the internet then try to install it then you get a message similar to the above. It does not install anything.

It seems to be caused by a faulty Microsoft Visual C++ redistributable package. The quickest 'cure' is to go into Control Panel then Programs and Features then REMOVE ALL Microsoft Visual C++ redistributable packages.

Then - reinstall them all. I found a single source here - https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/

Chromebooks / Problem trying to load Linux on Chromebook
« on: July 13, 2021, 06:01:36 pm »
If you have a new Chromebook and want to use Linux then you may have an issue. I had problems on my Asus C423 and had to research the issue as they didn't have an answer as to why it wouldn't load.

Found this on - https://www.androidpolice.com/2021/07/08/you-might-not-want-to-update-your-chromebook-to-the-latest-chrome-os-release-just-yet/

Google has pulled the latest version of Chrome OS 91. Reports have been emerging that some Chromebook owners are experiencing significant performance regressions on Chrome OS version 91.0.4472.147, the latest stable release. However, in the process of pausing the update on devices, Google has introduced another problem ? you can no longer install Linux on what has now become the latest release again, version 91.0.4472.114.

After pulling the problematic update to version 91.0.4472.147, Google is now pointing to v91.0.4472.114 as the most recent stable release. However, it looks like the Linux installer app hasn't received the memo regarding the pulled update yet. As reported by Chrome Unboxed, the Linux installer checks if you're running the latest version of the OS before it runs, and it looks like Google's servers still claim that version x.114 isn't the latest anymore, prompting users to update their Chromebooks. Since version x.147 is no longer available, that's not possible ? x.114 is simply the latest release now. Hence, you can't install Linux on the current release of Chrome OS 91 right now.


I had to tell Asus about this as they clearly didn't know.

UPDATE - THIS HAS NOW BEEN FIXED

General discussions / Windows 11
« on: June 24, 2021, 09:04:00 pm »
Windows 11 is here.

The minimum hardware requirements for Windows 11 include a PC with a dual-core 64-bit CPU, 4GB of RAM, and 64GB of storage. It will be a free upgrade for existing Windows 10 users.

Unless your PC is less than 2 years old it is unlikely that it will fit the minimum spec.

There is a tool to check compatability at -

Operational Status / zipzap.eu website no longer working
« on: May 24, 2021, 08:50:25 am »
www.zipzap.eu

While we still own the web site address, the site is not operational.

This is due to the fallout between the UK and the EU over Brexit. The EU have pulled the plug on the connection despite the fact that the UK is still part of Europe, meaning that the website and the associated email addresses are 'in limbo'. We are locked out just like all other UK users of .eu websites.

Use zipzap.co.uk instead.

How petty. Children!

TPN Invoicing / Faster pricing percentage updates
« on: March 05, 2021, 12:59:32 pm »
If you are doing a large global pricing update and your data is on a network then there is a quicker way of doing it.

Make a note of where your data is currently located. This appears at the top of the main screen.

Create three new directories on your local drive C: and call then MyOldBackup, MyNewBackup and MyData.

Ensure TPN Invoicing is not being updated and don't allow any changes while you carry out this procedure.

Go into Utilities and Backup. Backup your system to C:\MyOldBackup

Once done go into Utilities and Datapath. Alter the data directory to C:\MyData

Now go into Utilities and Restore Data.

Locate the file called BACKUP.ZIP in C:\MyOldBackup and restore this. You are now working with your existing data but on the local C: drive.

Perform your pricing changes.

When done go into Utilities and Backup. Backup the data to C:\MyNewBackup

Now go into Utilities and Datapath. Alter this back to your original network location.

Go into Utilities and Restore. Pick the file BACKUP.ZIP from C:\MyNewBackup and let it restore.

Your amended data is now on the network drive. You have a copy of the original data in C:\MyOldData

Updating on a local drive can be much faster than the network.

TPN Invoicing / Not responding during pricing update
« on: March 04, 2021, 08:48:35 pm »
Symptom - you get Not Responding message during very large pricing updates.

The message means it has not refreshed the screen and not that it has stopped. It is a Windows message.

To check this, simply press the CAPS LOCK key. Does the CAPS LOCK light go on? If CAPS LOCK works then it's still running.

Do not press CTL-ALT-DEL and terminate the program. Give it more time.

Apple / Update older Mac when normal update fails
« on: March 02, 2021, 04:47:11 pm »
Apple do not allow all older models to be updated to the latest version despite the fact that they are powerful enough.

If you get this then search for PATCHED SUR on the internet. This allows a different method of updating. My 2013 Macbook Pro has updated to Big Sur with this quite happily.

It gets round the software restrictions.

TPN Invoicing / VAT on non UK freight
« on: January 22, 2021, 08:51:00 am »
You cannot mix different VAT Rates on the same invoice as the VAT is applied to the net total.

The way to deal with mixed rates is to -

1. Create a new export account for the customer. In effect they have two account, one for UK and one for non-UK.
2. Set the new account to non-vatable
3. Enter non-UK in TPN Connect under the export account

The import should then deal with this. An invoice created under the account will be zero rated.
