Using MAC TimeMachine with OpenMediaVault

17 Mar, 2024

I am using TimeMachine to do my Mac backup since 2013 and every time i need to restore a file i have a success.
Last month i setup a Raspberry PI 3 with OpenMediaVault to create a NAS on my network. I have several computers at home that need a backup. The setup for the first Mac Book Pro using Moterey was ok, but my other Mac using MacOS Sonoma 14.4.
Using Sonoma i got the error "Apple: The operation can t be completed because the original item for "" can t be found: ". Searching on the web there is no one solution for the problem. I found the video bellow that is a compilation of several possible solutions. The solution 3/21 solve my problem after i logoff and logon again. https://yo

Firewall changes for container image pulls

05 May, 2023

Since June 2022 the Red Hat OpenShift operator index images (redhat/redhat/operator-index) have been served from registry.redhat.io using Quay.io as the backend. OpenShift itself already needs access to the Quay.io registry and CDN hosts as explained in its installation instructions, and so this change required no action from customers at that time. We are extending this to all Red Hat container images. This allows customers to benefit from the high availability of the Quay.io registry while simplifying the way Red Hat delivers container images and paving the way for future enhancements.

OpenShift User is not able to login again after deletion using web console

13 Jan, 2023

If a user has been deleted from the OpenShift web console, they will no longer be able to login. The user's account and associated resources will also be deleted. If the user needs access again, they will have to be re-created in the console. To recreate the user you can use the command : oc create user Use the oc create useridentitymapping command to map the identity to the user. Use the command oc get identities to lis all identities you have configured, an then map the user.
For example:
oc create useridentitymapping homeldap:Y249a2VuaW8sb3U9 kenio

Openshift-install CLI Tool – Crash – Unable to decode instructions

10 May, 2022

We started a CP4D installation on AWS, but without using AWS ROSA. We create a new cluster from scratch. In our lab everything worked perfectly but when the client went to do its installation the Openshift CLI displayed the following error message: assertion failed \inst.has.value(): failed to decode instruction: 0x0 After much analysis, we discovered that the client's Administrator was using a MacBook Pro M1 laptop. We found the solution at this link https://veducate.co.uk/

Migrating messages from Domino to Google using IMAP

20 Feb, 2022

It's only for messages. No calendar migration Imapsync command is a tool allowing incremental and recursive imap transfers from one mailbox to another. If you don't understand the previous sentence, it's normal, it's pedantic computer-oriented jargon. All folders are transferred, recursively, meaning the whole folder hierarchy is taken, all messages in them, and all message flags (\Seen\Answered \Flagged etc.) are synced too. Imapsync reduces the amount of data transferred by not transferring a given message if it already resides on the destination side. Messages that are on the destination side but not on the source side stay as they are. Get the tool here https://github.com/imapsyn
