Storj Non-Docker using SystemD

This is just basic hints, not a full guide This assumes you have some basic linux knowledge Download identity and storagenode from github (I like to download these things to /opt/storj/) Create auth token HERE Create identity HERE (This took about 4 hours on my node | E3-1280 V2) storagenode setup. This will create config file and other needed files in ~/.local/share/storj/storagenode/config.yaml and ~/.local/share/storj/storagenode/storage Now you need to edit ~/.local/share/storj/storagenode/config.yaml and make changes as needed (wallet, identity files and data storage locations, email, storage size)

How to create keystrokes on Debian

This is very useful when working with VPSes where you can’t paste into the VNC connection (maybe I’m doing something wrong and you can?). Below is a quick piece of code I use. This should be ran as the user and not root. This sleeps for 5 seconds so you can navigate to where you need. sleep 5s; xdotool type CODE_TO_TYPE_HERE This is very easy and simple, but since I just switched to Debian full time from Windows it was a nice/easy way.

Fix battery drain while sleeping with laptop

I recnetly decided to switch to Debian full time for my personal laptop (Lenovo Thinkpad X1 Yoga Gen 3), after using it for a week or so I noticed that when I closed the lid it would die after less than a day. After some googleing I found the answer and they are below. I also noticed that the machine never seemed to wake up like it did on Windows (just open it and it should come alive), after switching over to deep_sleep it fixed that issue.

dd Tricks

Here’s a couple tips and tricks while using dd on Linux You can view the status of an on-going dd command (I always forget to run with progress or the version you’re using doesn’t have it) You will need another terminal window. Not a problem for me as I always use tmux, some people say screen it better. Find PID of dd process -> ps aux | grep -v grep | grep dd

Sudo Fun

I always add a file into /etc/sudoers.d/, just remeber the last entry is trump, so it can overturn the first entries. Because of this I always like to name the files like below. /etc/sudoers.d/999_nick /etc/sudoers.d/001_rick /etc/sudoers.d/111_slick-rick /etc/sudoers.d/222_slick-nick This means if there’s an entry in 999_nick that conficts with any of the others it will trump the other configs. This is how to run without password and only specific program, this is useful, for example my telegraf config when it has to run an exec, but the telegraf user doesn’t have perms.

Two separate sonarr instances via systemd

Here is how to have two different Sonarr instances (for example 4k and standard deff). Change the location after --data= to wherever you want the data to be.

Basic InfluxDB CheatSheet

Here is a basic cheatsheet for InfluxDB I’ve learned from playing with the TIG stack How to find the hosts in the series. You run the below command and just go through the list to find the host you want to delete. You can delete with what you know the host is, but his is nice because it will insure there wasn’t a typo WHERE "host" = 'DESKTOP-NAME' Here is how you actually drop the data from the DB that way it’s not displayed in Grafana anymore
