For many releases, Rancher rejects self-signed certs, which makes it impossible to use from the command line. Here is finally a workaround!If you're getting something like:# rancher --versionrancher version v2.9.0# rancher login https://rancher..sslip.io --token token- --skip-verify      FATA[0000] Get "https://": tls: failed to verify certificate: x509The workaround is:Download cacert from the Rancher UI, go to Global Settings --> Show cacert --> Copy cert value and paste to local filerancher login https://rancher..sslip.io --token token- --skip-verify  --cacert

Running some versions of Gnome have weird issues with when it shows the "standard" three buttons (Minimize/Maximize/Close) at the top of a window. Some have it, some do not.A nice way around this is to just tell Gnome to ALWAYS show them. The following command will do that for you:gsettings set org.gnome.desktop.wm.preferences button-layout ":minimize,maximize,close"

Pretty cool, you can now utilize Active Directory to manage Linux user accounts/logins. This article takes you thru the steps needed to get Linux Mint 20 to join Active Directory.Install needed packagesThere are quite a few, but they are all needed to work together as they each handle one part of communicating between Linux and Active Directory.Open a Bash prompt and enter the following:sudo apt install realmd sssd sssd-tools libnss-sss libpam-sss krb5-user adcli samba-common-bin oddjob oddjob-mkhomedir packagekit samba python-dnspythonWhen all that gets installed, you will need to restart your Mint Linux machine.Edit krb5.confAfter your machine is restarted, you will need to edit the krb5.conf file to make it so Kerberos knows how to talk to your Active Directory domain (Note that a Kerboros "realm" and an Active Directory "domain" mean the same thing):sudo nano /etc/krb5.confLet say your Active Directory domain is myhouse.home, edit the krb5.conf file to resemble the following (Swapping myhouse.home for your domain name):[libdefaults] default_realm = MYHOUSE.HOME dns_lookup_kdc = true dns_lookup_realm = true[realms] MYHOUSE.HOME = { kdc = myhouse.home admin_server = myhouse.home master_kdc = myhouse.home default_domain = myhouse.home }[domain_realm] .myhouse.home = MYHOUSE.HOME myhouse.home = MYHOUSE.HOME[logging] kdc = SYSLOG:INFO admin_server = FILE=/var/kadm5.logNext, we need to ...

You don’t have to throw away your old PCs and laptops. Install a lightweight Linux distro on them and they’re as good as new.  Lightweight distros don’t even have to be used on old hardware. You can install them on some bleeding-edge hardware and get the ultimate performance. Most distros are portable and can run on a Live CD/USB, without a hard drive. Why should you use other OSes full of bloatware and unnecessary stuff when you can use a perfectly fine Linux alternative?https://thishosting.rocks/best-lightweight-linux-distros/

Windows 11 requires a machine with a TPM 2.0 chip. What if you don't have one? Well, here's a workaround: On Linux, install a TPM emulator and use that to install Windows 11 on KVM/QEMM.This article walks you though the process.If you want to go directly to the TPM 2.0 emulator, then click here.

A war is going on in my house. Yes, that’s right. I call it “The War of O.S.’s.” My wife prefers Mac. My son is clan Microsoft. And I come from the foreign land of Linux. However, in recent years, we have called a truce. I don’t bring up why I think Linux is better and they don’t try to sell me on why it’s not. As long as we keep to the treaty, there is peace at the Catron household. Well, maybe it’s not quite that bad.https://linuxstans.com/honest-view-of-windows-vs-linux/

Never thought I'd see the day, but it's here. The newest version now is Active Directory compliant and can be joined to an AD Domain. Group policies in Active Directory can now be used to manage Ubuntu workstations, and the workstations can freely access Active Directory resources (shares, etc.) using those AD credentials as a Single Sign On client.And... Built in support for the Linux version of Microsoft SQL Server 2019. And with that you can add Azure Data Studio which also runs on Linux, and gives you nearly all the abilities of SQL Server Management Studio (SSMS), even with on-premises SQL Servers - it doesn't have to be an Azure database.Pretty cool, check out more on Canonical's blog: Ubuntu 21.04 is here | Ubuntu

Had some problems connecting to my Linux Mint 20.04 machine from WIndows 10 Pro. After much experimentation and searching, finally found this document on how to do it right.How to access files on Linux from Windows 10 with a Samba Share – The WP GuruPS: When entering your credentials on WIndows 10 to connect to the Samba share, enter it like this: [LinuxServerName]\[UserName]  (eg: linux\joe)

GNOME 2 was very much agreed & accepted, people loved it. The disputes happened when GNOME 3 was created to be very different to the older GNOME 2. And GNOME 4 is just continuing the travesty.MATE was the lightweight version of the GNOME 2 replacement, aka a "fork". Cinnamon was the heavyweight replacement.GNOME 3 stopped the WIMP standard used by Xerox, before Apple popularized this. The official new version of GNOME 4 relies on the keyboard, at the cost of massive movements of the mouse and the trackball. One-handed cripples like myself no longer have the use of the two handed keyboard.Canonical's Unity also appealed to these GNOME 3 rebels, who seemed to hate the WIMP protocol.GNOME is now ignoring the landscape mode of most desktop screen displays. The top & bottom margins destroy the limited vertical spacing available to the display. They seem to prefer the letter box slit to become even more slitty. Usually my desktop displays have the top & bottom information bars set to "intelligent auto-hide". The better use of these important information bars are the left & right margins of the screen.It was argued that both GNOME 3 and Unity interfaces were trying to prepare for the newer users on the vertical displays, the smartphones. Unity disappeared. GNOME was in danger of disappearing, until just one charity person gave one very large survival donation to keep it alive.As it is now, Fedora seems to comply mostly to the standard GNOME interface. Most others including Canonical, make the ...

So you do an ls -l, but with extra-large files, you end up with a file size displayed that is nearly unreadable like:-rwxrwxrwx 1 root root 10113058787 Mar 30 17:39 filename.gzSaw lots of people coming up with perl scripts and arcane sed command lines to do this.But, it's already built in with GNU Core Utilities which is in just about any distro of Linux.ls -l --block-size="'1"This gives you something much more readable:-rwxrwxrwx 1 root root 10,113,058,787 Mar 30 17:39 filename.gzEnjoy!PS: This also works with du
