Find The IP Address Of A Linux Mint Computer

networking

Every computer connected to a network receives an IP address, and you might need to know your computer’s IP address for a variety of reasons. Fortunately, Linux Mint makes it easier to find your computer’s IP address through the System Settings utility.

To find your Linux Mint computer’s IP address, first launch the System Settings application by clicking on its icon in the mintmenu. After System Settings launches, scroll down to the Hardware section and then click on the icon for Network .

This will bring up the Network utility. In the left-hand pane of the window, the utility will list all of the available network connections on your computer. In the right-hand pane, it will show details of the currently selected network connection. To find the IP address for a specific connection, left-click on the connect for which you wish to find the address. The right-hand pane will then show the details, including both the IPv4 and the IPv6 addresses.

Create A Bootable Linux Mint Flash Drive

usbboot

When you installed Linux Mint on your computer, you might have you used a burned DVD-ROM to do it.

But, let’s face it – DVD-ROMs are a pain to use. Compared to hard drives or USB flash drives, they’re quite slow, since even the fastest optical drive can’t keep up with a hard drive or a flash drive. They’re also quite noisy, and it can become annoying to listen to the optical drive endlessly grinding away.

And depending on the age of the computer, there’s an excellent chance the optical drive might just break down. One of Linux Mint’s strengths is that it has lower system requirements and can be installed on older machines. But optical drives have motors, and motors break down. Occasionally attempting to install Linux Mint on an older machine will cause the optical drive break down from the strain of attempting to boot off a DVD

This is where a bootable USB flash drive comes into the picture. Linux Mint includes a utility that lets you turn a USB flash drive into a bootable USB disk. Using this modified flash drive, you can bypass the DVD-ROM drive entirely and boot a computer into Linux Mint using the flash drive (assuming the computer’s BIOS supports booting from the USB ports, of course). Flash memory has no moving parts, so it’s less likely to break down, and it’s also faster and quieter than a DVD-based installation. These flash drives are also useful for troubleshooting purposes – if you have a Windows system that won’t boot, for instance, you can boot it up from a Linux Mint USB flash drive, and copy any critical documents to an external hard drive.

Here’s how to create a bootable Linux Mint USB flash drive.

To create the bootable USB flash drive, you’ll need two things. The first is a USB flash drive, obviously, and it needs to be one gigabyte or larger in size. The second is an ISO image of a desktop Ubuntu disc. You can get the latest version of the desktop Ubuntu installation disc at this web address:

http://www.ubuntu.com/desktop/get-ubuntu/download

Once you’ve got both the ISO and the flash drive, you can begin. First, connect your flash drive to your Linux Mint computer. Then click on the mintmenu and search for “USB Image Writer” in the search field.

When the utility starts, it will ask for a Linux Mint installation disc. This is where the ISO file comes into play. Navigate the utility to your ISO file and then click the Write button.

You’ll then see a progress bar as the utility copies the Linux Mint files to your flash drive.

Note that this process may take several minutes.

Once it’s done, you’ll see a message informing you that the installation is complete.

You can now use your flash drive to boot a computer into Linux Mint.

Manage Disks With The Disk Utility In Linux Mint 18

diskutility

When using Linux Mint, there are many different ways to manage your disks, both your hard drives and your removable drives. However, there is one centralized location where you can manage all the drives connected to your computer. Using the Disks utility, you can format, eject, and view the used space on all your drives from one application.

To launch the Disks utility, click on the mintmenu. Once the mintmenu appears, type “disks” into the search field, and then click on the Disks icon when it appears. Linux Mint will then launch the Disks utility.

The Disks utility has two panes in its window. The left-hand pane lists all the drives, both internal and removable, connected to your computer. The right-hand pane displays details about whichever drive is currently selected in the right-hand pane.

The right-hand pane will show the type of drive, and the volumes upon the drive. It will also display the serial number, the total size of the disk, and the amount of free space on the drive. Additionally, it will list the serial number and the health status – if Linux Mint detects problems with the disk, it will display them here.

In the upper right-hand corner of the right-hand pane, you will see a gear button. Click on the button, and the Disks utility will list the available actions for that drive. Usually, they include ejecting the drive, formatting the drive, and creating a disk image based upon the contents of the drive. Finally, if the drive is removable, there will be an Eject button next to the gear button. Clicking on the Eject button unmounts the drive so you can safely remove it from your computer.

Find The IP Address From The Command Line In Linux Mint

 

Finding the IP address of your Linux Mint computer takes a few clicks of the mouse when you do it in the graphical interface. However, it’s actually quite a bit easier to find your computer’s IP address from the Terminal, Linux Mint’s command-line interface. To find the IP address from the Terminal, first launch the Terminal by going to the mintmenu, searching for “Terminal”, and then clicking on the icon for Terminal when it appears. You can also launch the Terminal by hitting the CTRL+ALT+T keys simultaneously.

Once the Terminal launches, type this command and then hit the ENTER key:

ifconfig

The ifconfig command will generate an output with a great deal of information.

Fortunately, most of it is useful. The “eth0″ refers to the first Ethernet connection on your system. The “indet addr” displays your system’s IP address, while “Mask” shows the subnet mask. “HWaddr” shows your Ethernet adapter’s MAC (Media Access Control) address, which is (theoretically) unique to each adapter. (Some wireless networks require you to supply your MAC address before allowing your system to connect.)

You can pipe the output from the ifconfig command to grep to quickly find the specific item you want. Let’s say you just want to find the IP address:

ifconfig | grep inet

This time, the output will limit itself to just the IP address.

Eject Removable Media In Linux Mint

ejectmedia

When using removable media on a Linux Mint computer, you will have to “eject” the removable devices from your computer. This term is a holdout from the old days of floppy disks when you would have to press a physical button to eject the disk from the drive. This holds true with optical discs, which still need to be physically ejected.

It is still a good idea to eject your USB drives before physically unplugging them from your Linux Mint computer.

Why not just yank out the USB flash drives and hard drives? When you connect a USB storage device to your computer, Linux Mint mounts the device as part of the filesystem. When you eject the device, Linux Mint first checks to make sure there are no open files or folders on the device, and then unmounts it from the system. By simply unplugging the device, you risk the chance of interrupting Linux Mint in the middle of writing to or reading from a file, which can cause data loss. It is better and safer to eject the device first. Fortunately, this doesn’t take much time at all.

There are two ways to eject devices. The first is to find the device’s icon on the Desktop and right-click on it. Select “Eject” or “Unmount” from the menu that appears (the actual term may vary by device) and Linux Mint will eject the device, allowing you to remove it safely. The second is to open a Nemo file manager window and look for the device you want to eject under the Devices heading in the left-hand pane. Next to each ejectable device you will see a small arrow. Click on the arrow button, and Linux Mint will eject the device, allowing you to remove it safely.

How To Burn Disc Images In Linux Mint

burningdisc

From time to time, you might hear people talking about burning an “image file” to a disc. They aren’t talking about pictures or graphics, but a kind of file that contains a snapshot of a disc. An image file (also called an ISO file) is a file containing the complete contents of a disc. The idea is that you then burn the image file to a CD or DVD disc, thereby allowing you create identical copies of the original disc. In fact, if you installed Linux Mint by downloading the image file and burning it to an installation disc, you’ve already used an ISO file. The Linux Mint installation is distributed via an ISO file, and to install it, people burn the ISO file to a disc (or transfer it to a USB flash drive).

Burning an ISO file to disc in Linux Mint is a straightforward process, and the ability is built right into Ubuntu, requiring no additional software or utilities. First, right-click on the ISO file you want to burn to disc, and from the top of the menu that appears, click on Open With and then Basero.

This will launch the Brasero disc burning utility.

Next, insert a CD-R disc or DVD-R disc into your optical drive, depending on the size of the image file. Then click on the Create Image button.

Linux Mint will then burn the image to your disc.

Burn Data Discs In Linux Mint 17

Mint17

If your Linux Mint computer includes an optical disc drive with burning capability, you can use Linux Mint to create “data discs” – optical discs that contain files and folders. You can create CD-R or DVD-R discs, discs that are burned once and then permanent. You can also create CD-RW or DVD-RW discs, discs that can be rewritten and erased (though note that rewritable discs can only be rewritten ten to twenty times before they break down).

To burn data discs, you use the Brasero disk-burning application, which comes included in the default Linux Mint install. To launch Brasero, click on the mintmenu, search for “brasero”, and then click on the icon for Brasero. When Brasero launches, click on the Data Project button.

Brasero will then open the New Data Disc Project window. Click on the Plus sign in the upper-left hand corner to add files to your data disc. Brasero will then let you navigate through your files and folders to select the files you wish to burn to your disk.

Note that the combined size of your files cannot exceed 700 megabytes for a data CD and 4.4 gigabytes for a data DVD. Once you have finished selecting the files, insert a burnable CD or DVD, and select the Burn button at the lower right-hand corner of the Brasero window.

Note that you must insert a burnable disc into your drive before hitting Burn, otherwise Brasero will create an image file based on your data, rather than actually burning a disc. Once the burning is done, you can eject the disc from your drive, and use it to transfer information to a different computer.

Format Removable Media In Linux Mint 17

Mint17

Linux Mint lets you connect removable media without much muss or fuss. Assuming your computer has the necessary USB ports you can connect any number of USB flash drives or hard drives, or even SD cards if your system has a card reader. However, to prepare removable media for use (or to erase it quickly), you need to format it. “Formatting” a removable drive simply means that the computer writes it with a filesystem in preparation for use. A filesystem is a method of organization information stored on a disk so the computer can find it again – NTFS, FAT, and ext4 are the most commonly used filesystems with removable Linux Mint computers.

To format a removable disk, first connect it to your computer. Once Linux Mint has recognized the device, an icon will appear for it on the Desktop. Click on the icon, and a Nemo window will appear. Your device will appear under the Devices category in the left-hand pane of the Nemo window. Right-click on the device’s link in that pane, and select Format from the menu.

The Format dialog box will then appear. You can select what kind of filesystem to use on the formatted drive. You have three options:

-A FAT32 drive will be readable and writable on almost all Windows, Linux, and Mac OS X systems.

-A NTFS drive will be readable and writable on almost all Windows systems and most Linux systems. Certain kinds of Linux systems may not be able to read from or write to an NTFS drive. Additionally, Mac OS X computers can read an NTFS drive, but they cannot write to it.

-An ext4 drive is compatible with all Linux systems. Note that neither Windows computers nor Macs will be able to read the drive.

In the Volume Label field, you can enter a volume label for the drive. After it is formatted, Linux Mint will use that name to list the device in Nemo.

After you have made your selections, click on the Format button, and Linux Mint will format the drive. Note that this will destroy all data currently on the drive – it is possible to recover data, but the recovery requires special software tools, and once the drive is overwritten the data is lost forever.

Check File & Folder Size In Linux Mint

Hard drives have gotten bigger over the years, but it’s still important to monitor your hard disk space usage, lest you accidentally fill up your hard drive. This is even more important on removable media, since it is much easier to fill up a four gigabyte flash drive than a one terabyte hard drive. Fortunately, there are a number of different ways to check the size of a file or a folder in Linux Mint.

To check the size of a file or folder, first launch Nemo file manager by clicking on the button for the mintmenu. By default, the mintmenu has an icon for Nemo pinned to it in the left-hand column, below the icon for the Terminal and above the button that locks the screen. Click on that icon, and Nemo will open to your home folder.

After Nemo has launched, navigate to the file or folder whose size you want to check. Right-click on the file or folder, and select Properties from the context menu. A dialog box will appear showing the size of the file or folder in question in the Contents line. If you right-clicked and selected Properties for a folder, the dialog box will also show the entire size of every single item contained within the folder.

You can also check the size of a folder from the Terminal command-line interface. To launch the Terminal, either go to the mintmenu, search for “terminal”, and click on the icon for Terminal, or hit the CTRL+ALT+T keys simultaneously. Once at the Terminal, use du command with the –s and the –h switches to determine the size of a file or folder. For instance, this command will display the size of your home folder:

du –sh ~
