NEW Section created to kick off Summer of 2021! --> Tip of the Week

As I am always discovering "new" ways to do "old" things, the "new" way is often better in one way or another! So I decided to create this new section that I hope to be able to add a new tidbit every week or so, depending on my own workload and available free time.

Here is the Tip of the Day section.

I hope you find it useful! :-)

Grub - GRand Unified Bootloader

Grub has been around for a long time, taking over the bootup role on most Linux installations from the "OLD" Lilo tool. Lilo stands for "LInux Loader", in case anyone is interested.

The configuration files for Grub are usually in /boot/grub2/grub.cfg, /etc/grub2.cfg and additional configuration settings in /etc/grub.d/. After a change has been made to any of the grub configuration files, you must re-apply those changes using the grub-mkconfig command as the root superuser. Here is an example of the usage of grub2-mkconfig:

[root@cos8vm54.dawgland.com:/boot/grub2]#grub2-mkconfig -o /boot/grub2/grub.cfg
 
Generating grub configuration file ...
done
[root@cos8vm54.dawgland.com:/boot/grub2]#

Scripts & Other Automation Tools

Display IP version 4 address of first network interface on a Linux machine one-liner:

Accessing Data on Windows and Other File Systems on Other Partitions

Coming soon - Detailed step-by-step instructions with screenshots detailing how to access your data on other partitions, such as Windows partitions on dual-boot/multi-boot machines.

XFS Recommended FSTAB settings

Here is an example of my recommended "/etc/fstab" mount option settings for XFS filesystems:

/dev/sda5 /mnt/data xfs rw,seclabel,noatime,attr2,discard,inode64,logbufs=8,logbsize=32k,noquota 0 0

Add Windows Partitions to FSTAB with Correct Read/Write Permissions Using FMASK & DMASK

Although it's easy enough to simply add the partition and mount point of your Windows installation to your /etc/fstab file, so as to allow it to be auto-mounted when the machine is booted up, having the "CORRECT" permissions is another major concern!

In the "old" days, we used to use "UMASK" with a value of 022 as the "standard" way of setting up Windows partitions to be mounted with correct read/write permissions. These days, the "preferred" method is using FMASK and DMASK.

When I first purchased the laptop I am typing on right now, it only had Windows 10 on it, so I used the Linux "parted" tool to shrink down the Windows partition, allowing me to then create Linux partitions on which I then installed my favorite desktop Linux distro, Fedora Linux. My example below assumes your UID & GID are 1000. Adjust as appropriate. If you don't know what a UID is, use Google to look it up. Basically, as it's name implies, UID(User ID), this is the unique number assigned to your user account. UID number 1000 is usually the first normal user created on a Linux system. GID is basically the same thing, but on a group level. On most Linux systems, your main group and group ID is the same as your username and user ID. For instance, in my case on this laptop I am currently using, my username is "jamie", case sensitive without the quotes, and my main group membership is also "jamie". My UID is 1000 and the GID of the "jamie" group is also 1000.

Here is the /etc/fstab contents of this laptop:

# /etc/fstab

GNOME Desktop Sharing Not Accessable from Windows --> Finally Fixed!!!

After many years of not being able to log into my Linux desktops from work laptops that of course have Windows installed on them, even within my own home network, gsettings comes to the rescure to resolve this long standing issue that's been a major inconveneice for me being a Linux guy working in the corporate world! The solution fixing the terminal menu below got me thinking that gsettings must be able to re-configure the default behavior of modern GNOME desktop's desktop shareing feature, which uses VNC, Virtual Network Computing, and specificially "x11vnc", it's default configuration is a security model not supported by most WIndows VNC clients. Therefore, the easy fix for me is to disable the security when using VNC on my local network(LAN). I actually do use VNC on through the internet as well, but always through an SSH tunnel, so it's highly encrypted!

Anyways, on to the fix. Within a terminal, as your normal user, type this gsettings command and hit the ENTER key:

[jamie@server.dawgland.com:~]$ gsettings set org.gnome.desktop.remote-desktop.vnc encryption "['none']"

If your system uses Vino, as many do, you may also have to type this command and hit ENTER:

[jamie@server.dawgland.com:~]$ gsettings set org.gnome.Vino require-encryption false

You can verify the above command worked and made the desired change by typing this command and hitting the ENTER key:

[jamie@server.dawgland.com:~]$ gsettings list-recursively org.gnome.Vino

You will have to scroll back up through all the data that the above command will provide to find the section you are looking for, or you can grep for it! For instance, modifying the above command to grep for the remote-desktop setting, type this command in a terminal and hit the ENTER key:

[jamie@server.dawgland.com:~]$ gsettings list-recursively org.gnome.desktop.remote-desktop.vnc | grep encryption

Restart your window manger or your entire computer, your choice, but logging out and back in should suffice. You should then be able to use VNC from any operating system, including Windows and MAC, along with Linux which has always worked regardless of the security modes and settings!

Fedora Terminal Missing Menu Fix

gsettings set org.gnome.Terminal.Legacy.Settings headerbar false

USB Flash Drive Info

Have a USB flash drive floating around, and not sure of it's capabilites? I just ran into that same exact issue, though with a brand new USB flash drive that's a really kewl 500GiB double-ended thumb-type drive, one end the standard USB-A connector, and the other end, an iPhone "Lightning" connector! Perfect for me with all my iPhones, iPads, and over 74 computers just in my house!

So, here's a simple one-liner to find out how fast it will run at, which is all I really wanted to kmnow at this immediate moment in time! Here it is:

[jamie@fc33hw01.dawgland.com:~]$ sudo lsusb -vvv | grep operate

And here is the output of the above command, showing the speeds the device is capable of operating at:

can't get debug descriptor: Resource temporarily unavailable
      Device can operate at Full Speed (12Mbps)
      Device can operate at High Speed (480Mbps)
      Device can operate at SuperSpeed (5Gbps)
can't get debug descriptor: Resource temporarily unavailable
can't get device qualifier: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get device qualifier: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get device qualifier: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
[jamie@fc33hw01.dawgland.com:~]$

You can totally ignore the lines starting with the word "cant", as they are meaningless. As you can see from the above output, the device can operate at "Full", "High", and "SuperSpeed"! Wonderful, I now know what I wanted. I hope you find that little tidbit useful. Of course, you do have to be a member of the "sudoers" group. So, on that note, why not create another little snippet on how to add a normal, already existing user account to the sudoers group, allowing them to "safely" run apps with eleveate administrator/root user privileges. I'll put it here: SUDO - Running commands and apps with elevated superuser/root/administrator privileges safely!

News

The LinuxJamie.com, TheBestLinux.com & Dawgland.com web and email servers have been moved over to a new box that should provide much faster performance and more stability. Previously, the servers had been running on a very old VMWare server on my Fedora desktop.

I have also maxed out the RAM memory that my new Xeon based server motherboard is able to use, doubling it from 16GB to 32GB!

Please let me know if you experience any performance or other issues with any of my websites.

The best way to let me know is by email, @ Jamie at Dawgland.com.
