OpenSSL error : unable to load Private Key

Linux Questions - Wed, 05/24/2023 - 12:09
Hi!

I have created a public-private keypair with ssh-keygen and I have both id_rsa and id_rsa.pub.

I'm trying to encrypt/decrypt files with openssl.

If I cypher the file with

Code: cat plain_file | openssl rsautl -encrypt -pubin -inkey /tmp/id_rsa.pub > /tmp/encrypted.txt it works.

I try to decypher it with the private key of the remitent user with this command

Code: cat /tmp/encrypted.txt | openssl rsautl -decrypt -inkey id_rsa But I get this error:

Code: unable to load Private Key
139651099592000:error:0909006C:PEM routines:get_name:no start line:../crypto/pem/pem_lib.c:745:Expecting: ANY PRIVATE KEY After some openssl manipulations, the contents of the private key begin with:

Code: -----BEGIN RSA PRIVATE KEY----- and then with
Code: -----BEGIN OPENSSH PRIVATE KEY----- By the way, the encryption didn't work at first with the ssh-keygen generated public file. I had to convert it with:

Code: ssh-keygen -f id_rsa.pub -e -m PKCS8 > id_rsa2.pub I'm pretty lost and I don't know what's going on.

Can you shed some light on this?

Thanks in advance!

PS: running Ubuntu 20.04

Mastering the Power of Head Command: Unlocking Efficient Data Handling in Linux

Linux Journal - Wed, 05/24/2023 - 11:00
by George Whittaker

In the realm of Linux, the head command holds immense potential for efficiently managing and extracting valuable information from files. We present a comprehensive guide to help you unleash the true power of the head command. From understanding its basic syntax to exploring advanced features, this article will equip you with the knowledge and techniques needed to become a proficient user.

Understanding the Basics of the head Command What is the head command?

The head command is a powerful utility in Linux used to display the beginning section of a file or the standard input. It is particularly useful for analyzing large files and extracting relevant data efficiently.

Syntax and Usage

The syntax for the head command is as follows:

head [OPTION]... [FILE]...

You can specify various options to control the output format and behavior of the command.

Exploring Essential Functionality Displaying the First -n Lines

To extract the first n lines from a file, use the following command:

head -n

This functionality is incredibly useful when you want to quickly preview the contents of a file or obtain a summary of its data.

Displaying the Default Number of Lines

If the number of lines is not specified, the head command displays the first ten lines by default. This default behavior can be altered using the -n option.

Unleashing Advanced Features Combining Multiple Files

To view the beginning section of multiple files at once, you can use the head command with multiple file names as arguments. For example:

head

This allows you to conveniently compare the initial contents of multiple files.

Using the -c Option

Apart from lines, you can also extract a specific number of bytes using the -c option. For instance:

head -c

This functionality proves invaluable when dealing with binary files or when you need to extract a specific chunk of data.

Optimizing Output and Usage Suppressing File Names

By default, the head command displays the file name along with the extracted lines. However, if you only want to view the lines without the file name, you can use the -q or --quiet option.

Someone please help me? Rare situation when I use any version or distribution of Linux...

Linux Questions - Wed, 05/24/2023 - 09:32
The situation is the following. Every time I connect a USB with any Linux distraction, if I use the Live CD or even once already installed and used periodically I have speed spikes from the microprocessor coolers and the power supply. It sounds like a pod for a few seconds and then drops to minimal noise levels. Which may be? It is something that has been happening to me for years only on desktop PCs.

Upgraded ubuntu desktop from 22.04 to 23.04 won't boot

Linux Questions - Wed, 05/24/2023 - 09:14
hi!

I just upgraded my ubuntu box from 22.04 to 23.04, and after that it won't boot. Just after printing "Loading initial ramdisk ..." it freezes (no HD lights flickering, keyboard not responding to anything)

I'm able to boot the machine from a ubuntu 23.04 in a usb stick, but not from my main hard-drive, even though them seem to be using the same kernel version.

Now I noticed that the USB stick doesn't use a `initrd` file. So i tried removing that from my /boot directory, and re-run update-grub. This made the kernel move forward, but then it panicked complaining that it couldn't moutn root in an /dev/nvme... device.

Any suggestions on what to try next ?

Is there a way to copy over the booting configuration (kernel, modules, etc) from the usb maybe ?

There is lots installed/configured in the box, so I wouldn't want to reinstall from scratch ...

Many thx!

Can't watch Hulu, Disney, Amazon on fresh install of F38

Linux Questions - Wed, 05/24/2023 - 09:09
I'm a bit of a distro hopper. I came back to Fedora on F37 and everything installed and worked fine. I upgraded to F38 and everything went smoothly. But there were some things that I installed and changed that I didn't like and decided to do a fresh reinstall of F38 today. Most everything is working as expected but I can't stream videos from Hulu Disney, or Amazon and a few others. Youtube, Netflix and HBO Max work fine.

I used this site for F37 , https://itsfoss.com/things-to-do-aft...alling-fedora/. It's been updated for F38. When I get to the load multimedia steps the first 2 steps work as expected but the third gives lots of errors saying there are conflicts (sudo dnf group upgrade --with-optional Multimedia). Below is the error messages received.
