Gentoo

If you’re here to find out how to setup network connection to hidden wifi access point, you might want to check this post: How to Connect to Hidden Wifi Using nmcli instead. This post documents how I fix an issue of wifi connection on a laptop running Gentoo to a hidden access point. The problem is that the wifi connection doesn’t automatically connect despite I’ve set the autoconnect.connection yes. ❯ nmcli con show CamBlue | grep -i autoconnect connection.autoconnect: yes connection.autoconnect-priority: 0 connection.autoconnect-retries: -1 (default) connection.autoconnect-slaves: -1 (default) I don’t remember having done anything special on the Fedora laptops connecting to the same the network; and this problem didn’t exit on any of those Fedora machines at all. ...

After many and many weeks, I finally got libvirt working on this Gentoo machine. Before revealing how I’ve fixed this problem, let’s go through what the issues were. On this Gentoo I run Firewalld with nftables as backend. An alternative to nftables is iptables, but since nftables is newer and is becoming the default backend for more and more distribution including Fedora, I think it’s a good thing to adobt it early. ...

Just a few a days ago, I wrote a blog post about Pairing Bluetooth Mouse on Command Line on a Fedora laptop. So why do I need to write another post about doing the same thing on Gentoo? Well, as it turned out, I need a bit more than just turning on the bluetooth service and pairing the mouse. My Gentoo’s installation is very minimal, and I think this gives me an excuse to document on how I’d solve or get this working on Gentoo. ...

On Fedora or CentOS, on way to find out what package providing a file we can use yum whatprovides [FILENAME] or dnf whatprovides [FILENAME] on a DNF-aware system. # dnf whatprovides tmux Last metadata expiration check: 2:33:06 ago on Wed 09 Sep 2020 09:45:07 PM AEST. tmux-3.0a-2.fc32.x86_64 : A terminal multiplexer Repo : @System Matched from: Provide : tmux = 3.0a-2.fc32 tmux-3.0a-2.fc32.x86_64 : A terminal multiplexer Repo : fedora Matched from: Provide : tmux = 3.0a-2.fc32 I really need this similar tool on Gentoo, and it looks like the emerge command doesn’t have this function built it. Fortunately, there is a utility called e-file (provided by pfl package) which kinda provides this whatprovides option as in yum and dnf. ...

Let’s find out the name of the package using the awesome eix command, and install that package. ~ # eix usbguard * sys-apps/usbguard Available versions: ~0.7.6-r1 ~0.7.8 {bash-completion dbus ldap policykit static-libs systemd} Homepage: https://github.com/USBGuard/usbguard Description: Daemon protecting your computer against BadUSB ~ # emerge --ask sys-apps/usbguard These are the packages that would be merged, in order: Calculating dependencies... done! !!! All ebuilds that could satisfy "sys-apps/usbguard" have been masked. !!! One of the following masked packages is required to complete your request: - sys-apps/usbguard-0.7.8::gentoo (masked by: ~amd64 keyword) - sys-apps/usbguard-0.7.6-r1::gentoo (masked by: ~amd64 keyword) For more information, see the MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook. It looks like we need to unmask usbguard. ...
