I have looked at cron before, but what if someone else has gained access to your Linux system and added a cron job without your knowledge? Linux systems such as Raspbian store the crontabs as files (named for each user). A user’s crontab can be found under the /var/spool/cron/crontabs directory. You may need to escalate … Continue reading Viewing All Users Cron Tabs / Cron Jobs (Linux)
During my last post on Cron I hoped that my work may appear somewhere other than my website. Good news readers, my introduction to Cron is being published within The MagPi magazine issue 73 (September 2018). From the 30th August 2018 the issue can be purchased for £5.99, purchased on the Google PlayStore or the Apple AppStore, … Continue reading Cron / The MagPi Magazine (Raspberry Pi)
I’ve spent the last few blog entries going over Cron stuff and think the issue ( DISPLAY=:0 played a part) was down to remote accessing and the way sessions display screens. I won’t go into too much detail tonight as I’m hoping that my work may appear somewhere else soon (fingers crossed). In the mean … Continue reading Cron – or a general update
After yesterdays post around using a remote desktop connection to connect from my Mac to my Pi I decided to add some cron jobs on the Pi so that it would reboot every night and after rebooting it would log in (automatically using raspi-config settings) and then fire me up a Terminal session and a web … Continue reading Cron Not Displaying GUI Applications / Terminal Display (Raspberry Pi / Linux)
I previously wrote about using some Python to stop AWS EC2 instances that had the tag “office_hours” and indicated that this could be automatically run via AWS Lambda. This blog post is a brief follow up with some notes on creating the Lambda function, using the Python from the previous blog post. Using AWS Lambda … Continue reading AWS Lambda – Stop Instances Outside Office Hours (Python / AWS)
Log files are a brilliant feature of any piece of software / operating system. However, over time they can take up space and become a pain to remove. In this blog post I am going to look at a quick bash script that can be used via cron to delete older log files. The Set … Continue reading Deleting Old Files With BASH / Removing Old Log Files with BASH (Linux)
I will hold my hands up here and admit, I am not great at advertising my website on social media. When posting a new blog post it auto generates a link on some social media sites for me, but I rarely ever repost links especially for my older blog posts. Today I am hoping to … Continue reading AutoTweeting WebLinks (Python)
Jenkins is a tool to help with Continuous Integration / Continuous Delivery (CI / CD). I originally looked at installing Jenkins as a Java web app on my Raspberry Pi during this post: https://geektechstuff.com/2019/05/26/installing-apache-tomcat-jenkins-raspberry-pi/ . I am now hoping to expand a little bit more on using Jenkins by building a freestyle project that connects to … Continue reading Jenkins – Connecting To GitHub and some Python
I have expanded my previous port scanner to have a little bit more functionality e.g. identify webpages, save to a log file and to either run interactively or run without interaction. I was thinking the non-interactive version could be scheduled via a cron job. ———- #! /usr/bin/python3 # geektechstuff Security Python # modules to import … Continue reading Network / Port Scanner V2 (Python)
Today I received a phone call and SMS text message that a flood alert had become active for the area I live in. After making preparations incase the alert severity increased I got to thinking; is there a better way to be warned about potential floods? One (quick) Google search later and I found that … Continue reading UK Flood Alert / Flood Data (Python)
