How To: Disable Sleep/Hibernation on Ubuntu Server

*~grumbles~*

Seriously! My log contained lovely hints like:

[code]Apr 3 12:18:27 server systemd[1]: Reached target Sleep.[/code]

[code]sudo systemctl mask sleep.target[/code]

[code]sudo systemctl mask suspend.target[/code]

[code]sudo systemctl mask hibernate.target[/code]

[code]sudo systemctl mask hybrid-sleep.target[/code]

[code]systemctl status sleep.target[/code]

Finally, thanks for reading. Like always, I love the feedback and the newsletter is still there waiting for you to sign up. If you do sign up, I chose a pretty crappy domain name and you should probably check your spam inbox for the confirmation email.

How To: Make Ubuntu Show Asterisks When Typing Password

shoulder-surfing won’t be able to see the number of characters in your password. This is how to get some feedback when you enter your password in the terminal.

[code]sudo nano /etc/sudoers[/code]

Enter your password and hit enter, of course. (This will be the last time you enter your password in the terminal without some sort of visual feedback!)

Now it gets a little tricky. 

Use the down arrow until your at the start of the line that says:

[code]Defaults            mail_badpass[/code]

Press the ENTER button. This should move that line down and leave a blank line above it. Use the arrow button to move up to that blank line and enter:

[code]Defaults[/code]

Then press the TAB button on your keyboard. This will move the cursor to the right location. Add this text:

[code]pwfeedback[/code]

The entire line should look something like:

[code]Defaults            pwfeedback[/code]

Press CTRL + X, then Y, and then ENTER.

[code]sudo apt update[/code]

asterisk feedback in the terminal

See? Asterisks for feedback in the terminal.

How To: Enable a Swapfile

no swapfile

[code]sudo fallocate -l 8G /swapfile[/code]

Why 8 gigabytes when I have ample RAM and an SSD? Because I never, ever want to worry about it again. I want to be able to open up every app I have and leave them open for a month. You do you and decide how big you want it to be!

[code]sudo chmod 600 /swapfile[/code]

[code]sudo mkswap /swapfile[/code]

And turn it on with:

[code]sudo swapon /swapfile[/code]

[code]sudo nano /etc/fstab[/code]

And add this at the bottom of that document:

[code]/swapfile none swap sw 0 0[/code]
