0 (0)

30 April 2020

I have a laptop with Arch Linux. It’s suspended with the systemctl suspend. The issue: after it’s wake up there is no sound. From the information found during the investigation (see links below) the issue happens because of the NVIDIA drivers and isn’t specific to the Arch Linux – can happen with any other Linux… Read More: Linux: no sound after suspend/sleep – solution0 (0) »

26 February 2020

Currently, I’m using KeePass as passwords, RSA-keys, and as the Freedesktop SecretService, see the KeePass: an MFA TOTP codes, a browser’s passwords, SSH keys passwords storage configuration and Secret Service integration post. The first issue I faced with during such a setup is the fact that KeePass’ database is synced between my computers (it’s database… Read More: Linux: gnome-keyring setup as Freedesktop SecretService0 (0) »

We have a Docker image with NGINX, PHP-FPM, and Supervisor. In the same image, we have our PHP application included, which outputs its errors to the /dev/stderr as per its php.ini file: … [global] error_log=/dev/stderr … The problem is, that if run kubectl logs –  there will be no error output from the application. So,… Read More: Linux: PHP-FPM, Docker, STDOUT and STDERR – no an application’s… »

I’m using Calibre for my e-books library management for many years, but until today always used its desktop version. A couple of days ago I found the Calibre Web project – the same library, working with the same database, but accessible via a browser. The idea is to move away from storing books in Google… Read More: Calibre Web: home in-browser online-library with Nextcloud storage and Moon+… »

13 December 2019

As a follow-up to the SSH: RSA keys, and ssh-agent for SSH keys and their passwords management post. The idea now is to make simpler to work with password-protected SSH keys, to avoid the necessity to enter a password each time when you want to load a key to the ssh-agent. One of the possible… Read More: KeePass: SSH keys passwords storage and decryption on Linux0 (0) »

Chromium: Linux, keyrings && Secret Service, passwords encryption and store
0 (0)

10 December 2019

One of the motives to go deeper into the keyrings (see the What is: Linux keyring, gnome-keyring, Secret Service, and D-Bus post) was the fact that Chromium, surprise-surprise, keep passwords unencrypted if a Linux system has no keyring and/or Secret Service enabled. So, let’s try to find how and where Chromium store passwords, and the… Read More: Chromium: Linux, keyrings && Secret Service, passwords encryption and store0… »
