So I’ve tried to configure a self-hosted Roundcube container and set up an iCloud account with a custom domain address. Something like what this guy wanted to do a couple of years ago. Unfortunately, there was no tutorial available on the internet, so here I am creating one for you :) I’m using docker compose in my local selfhosted lab, so the first thing to do was to get the correct docker-compose....
For today’s post I will walk you through the process of setting up a web-app testing environment automatically using ansible. I will split this into 2 parts. First part will focus on creating the automation needed to deploy the containers on proxmox. Second part is about creating the tester tool solution. Assumption: you already have a proxmox server in place. your ansible controller has passwordless ssh access enabled to the proxmox server....
This is a quick one, I had to get the SN of my external screens recently and I thought I should share the powershell command I used for this task. This works only on your local machine, for AD nodes there are other options out there on the internet. Get-WmiObject WmiMonitorID -Namespace root\wmi |Select-Object @{l="Manufacturer";e={[System.Text.Encoding]::ASCII.GetString($_.ManufacturerName)}},@{l="Model";e={[System.Text.Encoding]::ASCII.GetString($_.UserFriendlyName)}},@{l="SerialNumber";e={[System.Text.Encoding]::ASCII.GetString($_.SerialNumberID)}} This should return something like this: PS C:\Users\costin> Get-WmiObject WmiMonitorID -Namespace root\wmi |Select-Object @{l="Manufacturer";e={[System.Text.Encoding]::ASCII.GetString($_.ManufacturerName)}},@{l="Model";e={[System.Text.Encoding]::ASCII.GetString($_.UserFriendlyName)}},@{l="SerialNumber";e={[System.Text.Encoding]::ASCII.GetString($_.SerialNumberID)}} Manufacturer Model SerialNumber ------------ ----- ------------ HPN HP E243i 6CM90XXXX HPN HP E223 3CQXXXXX
In case you want to run a quick performance test (in simple terms of access to DB) on a PostgreSQL server, this can be done quickly through a python module called psycopg2. This is the python script I’ve used: #!/usr/bin/python3 import psycopg2 from psycopg2 import Error import time def create_connection(): """ create a database connection to a PostgreSQL database """ try: conn = psycopg2.connect( database="postgres", user="postgres", password="postgres", host="1.2.3.4", port="5432" ) print('Successfully Connected to PostgreSQL') return conn except Error as e: print(e) def check_table_exists(conn): """ check if a table exists in the PostgreSQL database """ cur = conn....
Recently I had to fix a vCenter Server that was stopped working. The webpage displayed the following error, and the automated backup jobs stopped working. Could not connect to one or more vCenter Server systems: https://$VCENTER_FQDN:443/sdk The version is rather old and end of life (6.7), so VMware support was out of the question. Which means I had to do it all by myself. Great… After checking the logs for obvious errors, I’ve noticed that most services were stopped....
