When trying to find why my ospf configs were not sending the correct costing from Linux -> Cisco devices, I found some useful commands that I thought I would note down for future reference. Linux – Using vtysh My ospfd.conf looks something like this: You can see the costs on linux using the vtysh command: […]

I have a Lenovo X1 Carbon 4th Gen, running Ubuntu 20.04 – it’s a great laptop, with a 14″ display and a 1080p screen. However, if you run it at 1X display scaling, everything is just a bit too small for comfort. I have found the best display scaling factor for it is 125%. Ubuntu […]
This is a simple ansible config that will set your machine to use the bfq scheduler: Put this in a file called enable_bfq_playbook.yml and then run it with ansible-playbook: Reboot, and you should now have bfq enabled on your disk:

Reading Jlelse’s blog here (https://jlelse.blog/dev/telegram-go/) I realised there is another alternative to using an automation tool like IFTTT or Microsoft Power Automate, is to use a messaging app like Discord or Telegram. Previous post on the same topic:https://jaytuckey.name/2020/04/21/making-a-simple-phone-notification-tool-using-ifttt-available-on-a-free-account/ Creating the Discord Notification Webhook To make a personal notifier using discord you will need to make […]

I previously made a guide on how to create a notifier using Microsoft Power Automate: https://jaytuckey.name/2020/04/21/making-a-simple-phone-notification-tool-using-microsoft-power-automate-previously-microsoft-flow/ However, the Request trigger used in that flow is only available on a premium account so many people won’t be able to use it without a work account. For those people, here’s how to make the same thing using […]

Note – The “Request” trigger used in this post is only available on a Premium Power Automate account. If you want this for personal use, I suggest you look at using IFTTT instead, see my guide here: https://jaytuckey.name/2020/04/21/making-a-simple-phone-notification-tool-using-ifttt-available-on-a-free-account/ Many of us have access through our work to Microsoft Power Automate, previously called Microsoft Flow. With […]
Trying to SSH to a Cisco switch from Ubuntu 20.04 you may get this error. I’ve noticed the same thing from Redhat RHEL 8: This error is because Ubuntu 20.04 has disabled the SHA1-based key exchange methods after some attacks have been found on SHA1. To work around this issue for Cisco switches you can […]
I have been trying to find a way to create a regular backup of my Cisco switch’s running-config, so I can store it in my normal backups. However, after searching online I was able to find some tools that were almost there, but nothing that was quite as flexible as I needed, so I wrote […]
I recently decided to move away from using my Wifi access point as a router, and instead use an old my Raspberry Pi 2 as my router. I had a few reasons for doing this: I wanted a more up-to-date device as my internet facing box. My Wifi AP hasn’t received any firmware updates in […]
