Send Firefox Defaults

Send Large Files with Firefox Send

By Bob Liebl | March 17, 2020

Firefox has a new service for sending large files up to 2.5 gigs in size. Most of the free email services like Outlook, Gmail, Yahoo, and others have limits on the size of the attachment you send in an email. I believe Gmail offers the largest at 25 Mb. 

Now with Firefox free service, you can send files up to 2.5 gigs in size. That’s huge. 

You can even password the file. No one can download the attachment unless you use the correct password.

You don’t have to have a Firefox account to send or start receiving files with Firefox Send.

Without an account, the default settings are one day and one download. After that, your attachment will disappear from the net.

Send Firefox Defaults

 

If you do sign up for a free account, you get more options like:

  1. Send files larger than 2.5 gigs
  2. You can change how many days before it disappears from the net.
  3. You can change how many downloads before it disappears from the net
  4. You can put a password on it, so unless you know it, you can’t download it.

Let’s Get Started:

Send files

Click the Firefox Account icon in the toolbar.
Send Firefox file transfer

 

 

  1. Click Firefox Send. Or go to this URL address. The Firefox Send page, https://send.firefox.com/, will open. 
  2. Click Select files to upload and select the files you want to send.
  3. Set an expiration and password (optional) for your files. By default, the link will expire after one download or one day.
  4. Click Upload.
  5. Please copy the link and send it to your recipient.

Receive files

You don’t need a Firefox Account or even Firefox to receive data using Firefox Send.

  1. Click the link to download the files.
  2. Enter a password if required.
  3. Click the Download button.

Tip! Sign up for a free Firefox Account to send even larger files.

It’s effortless to use and works great. Your upload speed is dependent on your ISP, so sorry, can’t help you there when you’re uploading huge files.

Hope this helps

Linux Distros for Old Laptop 2019

By Bob L | October 24, 2019

Do not discard that old PC or laptop yet. You can use a lightweight Linux distro to make them as good as new. Some of these Linux distros are specifically for use in older machines.

You can use any of the lightweight Linux distros and bring your old machine back to life. In as much we focus on the old distros, we do have some new releases that do not require many resources that can re-invent your old computers.

Are you in any or all of the situations below?

Your computer is but still feel like you can revive it
Your computer is modern but runs on low power
You need to install a modern computer to reserve resources to other demanding tasks
If you find yourself in any of the above situations, then the best choice of action would be to start looking for the best lightweight Linux distros for old computers.

1. Lubuntu

Minimum System Requirements

Pentium II or Celeron CPU with Physical Address Execution (PAE)
128 MB of Ram
2 GB of hard drive
As the name suggests, Lubuntu is a member of the popular Ubuntu family. It runs on the LXDE desktop environment and as such it one of the official flavors of Ubuntu. Lubuntu works well with old computers, and its lightness is visible in its speed and support for older hardware.

It has a set of applications and software with tools like office, internet, graphics applications, and related utilities. The applications running within Lubuntu utilize fewer resources, and they have better alternatives if need be.

You can access thousands of additional packages via the Ubuntu software repository. When the Operating System is merged with Razor-qt to develop LXQt.

2. Linux Lite

Linux-Lite
Minimum System Requirements

700 MHz Processor speed
512 MB of RAM
Resolution of 1024 X 768
5 GB of hard disk space
From its name “lite,” it means there is no need for high-end hardware requirements. Even a beginner will find a lot of comforts using it for the first time. Linux Lite runs on Ubuntu Long Term Support (LTS) with a support life of up five years.

Chmod Command in Linux File Permissions

By Bob L | September 17, 2019

In Linux, access to the files is managed through the file permissions, attributes, and ownership. This ensures that only authorized users and processes can access files and directories.

This tutorial covers how to use the chmod command to change the access permissions of files and directories.

Before going further, let’s explain the basic Linux permissions model.

In Linux, each file is associated with an owner and a group and assigned with permission access rights for three different classes of users:

  • The file owner.
  • The group members.
  • Others (everybody else).

File ownership can be changed using the chown and chgrp commands.

There are three file permissions types that apply to each class:

  • The read permission.
  • The write permission.
  • The execute permission.

This concept allows you to specify which users are allowed to read the file, write to the file, or execute the file.

File permissions can be viewed using the ls command:

ls -l filename.txt

Copy

-rw-r--r-- 12 linuxize users 12.0K Apr  8 20:51 filename.txt
|[-][-][-]-   [------] [---]
| |  |  | |      |       |
| |  |  | |      |       +-----------> 7. Group
| |  |  | |      +-------------------> 6. Owner
| |  |  | +--------------------------> 5. Alternate Access Method
| |  |  +----------------------------> 4. Others Permissions
| |  +-------------------------------> 3. Group Permissions
| +----------------------------------> 2. Owner Permissions
+------------------------------------> 1. File Type

Copy

The first character shows the file type. It can be a regular file (-), directory (d), a symbolic link (l), or any other special type of file.

The next nine characters represent the file permissions, three triplets of three characters each. The first triplet shows the owner permissions, the second one group permissions, and the last triplet shows everybody else permissions. The permissions can have a different meaning depending on the file type.

In the example above (rw-r--r--) means that the file owner has read and write permissions (rw-), the group and others have only read permissions (r--).

Each of the three permission triplets can be constructed of the following characters and have a different effects, depending on whether they are set to a file or to a directory:

Effect of Permissions on Files

Permission Character Meaning on File
Read - The file is not readable. You cannot view the file contents.
r The file is readable.
Write - The file cannot be changed or modified.
w The file can be changed or modified.
Execute - The file cannot be executed.
x The file can be executed.
s If found in the user triplet it sets the setuid bit. If found in the group triplet, it sets the setgid bit. It also means that x flag is set.
When the setuid or setgid flags are set on an executable file, the file is executed with the file’s owner and/or group privileges.
S Same as s but the x flag is not set. This flag is rarely used on files.
t If found in the others triplet it sets the sticky bit.
It also means that x flag is set. This flag is useless on files.
T Same as t but the x flag is not set. This flag is useless on files.

Effect of Permissions on Directories (Folders)

In Linux, Directories are special types of files that contain other files and directories.

Permission Character Meaning on Directory
Read - The directory’s contents cannot be shown.
r The directory’s contents can be shown.
(e.g. You can list files inside the directory with ls.)
Write - The directory’s contents cannot be altered.
w The directory’s contents can be altered.
(e.g. You cannot create new files, delete files ..etc.)
Execute - The directory cannot be changed to.
x The directory can be navigated using cd.
s If found in the user triplet, it sets the setuid bit. If found in the group triplet it sets the setgid bit. It also means that x flag is set. When the setgid flag is set on a directory the new files created within it inherits the directory group ID (GID), instead of the the primary group ID of the user who created the file.
setuid has no effect on directories.
S Same as s but the x flag is not set. This flag is useless on directories.
t If found in the others triplet it sets the sticky bit.
It also means that x flag is set. When the sticky bit is set on a directory, only the file’s owner, the directory’s owner, or administrative user can delete or rename the files within the directory.
T Same as t but the x flag is not set. This flag is useless on directories.

The general form of the chmod command take the following form:

Enable DNS-over-HTTPS (DoH) in Firefox

By Bob L | September 14, 2019

A step by step guide to enable DNS-over-HTTPS (DoH) support in the Firefox browser.

By for Zero Day | | Topic: Security

 

The DNS-over-HTTPS (DoH) protocol is currently the talk of the town, and the Firefox browser is the only one to support it.

However, the feature is not enabled by default for Firefox users, who will have to go through many hoops and modify multiple settings before they can get the DoH up and running.

But before we go into a step-by-step tutorial on how someone can enable DoH support in Firefox, let’s describe what it does first.

How DNS-over-HTTPS works

The DNS-over-HTTPS protocol works by taking a domain name that a user has typed in their browser and sending a query to a DNS server to learn the numerical IP address of the web server that hosts that specific site.

This is how normal DNS works, too. However, DoH takes the DNS query and sends it to a DoH-compatible DNS server (resolver) via an encrypted HTTPS connection on port 443, rather than plaintext on port 53.

This way, DoH hides DNS queries inside regular HTTPS traffic, so third-party observers won’t be able to sniff traffic and tell what DNS queries users have run and infer what websites they are about to access.

Further, a secondary feature of DNS-over-HTTPS is that the protocol works at the app level. Apps can come with internally hardcoded lists of DoH-compatible DNS resolvers where they can send DoH queries.

This mode of operation bypasses the default DNS settings that exist at the OS level, which, in most cases are the ones set by local internet service providers (ISPs).

This also means that apps that support DoH can effectively bypass local ISPs traffic filters and access content that may be blocked by a local telco or local government — and a reason why DoH is currently hailed as a boon for users’ privacy and security.

This is one of the reasons that DoH has gained quite the popularity in less than two years after it launched, and a reason why a group of UK ISPs nominated Mozilla for the award of 2019 Internet Vilain for its plans to support the DoH protocol, which they said would thwart their efforts in filtering bad traffic.

As a response, and due to the complex situation in the UK where the government blocks access to copyright-infringing content, and where ISPs voluntarily block access to child abuse website, Mozilla has decided not to enable this feature by default for British users.

The below step-by-step guide will show Firefox users in the UK and Firefox users all over the world how to enable the feature right now, and not wait until Mozilla enables it later down the road — if it will ever do. There are two methods of enabling DoH support in Firefox.

Method 1 – via the Firefox settings

Step 1: Go to the Firefox menu, choose Tools, and then Preferences. Optionally type about:preferences in the URL bar and press enter. This will open the Firefox prerences section.

Step 2: In the General section, scroll down to the Network Settings panel, and press the Settings button.

Automate your Linux system tasks with cron

By Bob L | September 14, 2019
It’s all about timing with cron, the scheduling daemon. Cron allows system administrators to schedule and automate scripted tasks with ease and precision.

Posted September 13, 2019 byKen Hess (Red Hat)

It might surprise the saltiest of system administrators to know that there is no Linux cron command. The cron daemon (crond) is a system-managed executable that runs in memory with which users may schedule tasks. The user command to work with the cron service is crontab (cron table). The crontab file is a simple text file that instructs the cron daemon to perform a task at a certain time or interval. Any user may schedule cron tasks or jobs on a system. The task runs under the user account from which it was created. In other words, if you create a cron task, it runs with your user account’s permissions. The same is true for any user on the system, including the root user.

Using cron

You can issue the man crontab command to see all possible options, but there are generally two that work for most users: -l (list) and -e (edit).

To see a list of your configured cron tasks, use:

$ crontab -l
no crontab for khess

I have no cron tasks running yet. To create one, I need to edit my crontab file:

$ crontab -e

Note: There is no file name or designation of any kind required when creating a crontab entry. Each user has only one crontab file and you add all tasks to it.

There is nothing particularly special about the crontab editor except that, if you don’t have a specific editor defined with either the VISUAL or the EDITOR environment variable, then your editor is probably either vi or vim.

Note: If you don’t know how to use vi or vim, please refer to my article, An introduction to the vi editor.

Press the I key to enter INSERT mode and begin setting up your crontab entry. The crontab file has a specific syntax to it. See the image below:

crontab syntax
“Cron Job” by xmodulo is licensed under CC BY 2.0

Making it work

As you can see from the image, the positioning of your entries has meaning, and the entries are separated by spaces. An asterisk (*) means every or all, as in every minute or all hours, every day, and so on. In other words, the image currently illustrates a crontab entry for a script that will run every minute of every day. This practice, while rare, does exist in some instances. However, for most cron tasks, you will need to be more specific.

Note: Before setting up a cron task, run your script or command to see if you have any problems with permissions or paths.

It’s a good practice to provide the full path to any executable inside a script. Likewise, you should also provide the full path to executables or scripts in your crontab entries.

For example, if you have a script that needs to create a file from the dmesg command once a day at 1pm, your entry looks like the following:

* 13 * * * /usr/bin/dmesg > ~/dmesg.txt

And if you want to email this file to yourself, you can add an additional entry into your crontab:

2 13 * * * /usr/bin/mail khess@domain.com < ~/dmesg.txt

Save the file by exiting it as you would exit vi or your default editor. There is nothing special you have to do to enable this edited crontab. The cron daemon checks for the existence of entries in the /var/spool/cron directory automatically. For example, my crontab is /var/spool/cron/khess and contains the two entries above.

The cron daemon runs as root so it can read the directory’s contents since only the root user has access to this directory. It would be a serious security violation for other users to access /var/spool/cron and read the crontab entries for other users on the system.

More examples

For the following examples, assume that you have a script, backup.sh, that you want to schedule on your system. You’ve placed all your system scripts in /etc/scripts, which is a directory that only root has access to.

To schedule the backup script to run every night at 2am, open the root user’s crontab:

$ sudo crontab -e

then enter the following:

* 2 * * * /etc/scripts/backup.sh

Save and exit the file.

Let’s try something a little more advanced. Schedule the backup script to run at 2am every Monday. Now, what does the crontab entry look like?  Refer back to the crontab syntax image for hints:

* 2 * * 1 /etc/scripts/backup.sh

The 1 in the fifth column instructs cron to run this script on Monday.

Rather than have your special backup script run every Monday, run it on the 15th of every month:

* 2 15 * * /etc/scripts/backup.sh

What if the backup script only backs up a single mission-critical directory? You want that directory’s contents backed up every 15 minutes. Here’s how that would look, which isn’t 100% intuitive:

*/15 * * * * /etc/scripts/backup.sh

The traditional method of setting this every 15-minute schedule looks like the following:

0,15,30,45 * * * * /etc/scripts/backup.sh

And similarly, if you want to run the script only Monday through Friday, your entry changes to:

*/15 * * * 1,2,3,4,5 /etc/scripts/backup.sh

As you can see, cron scheduling is easy once you understand the syntax. The only real stumbling blocks you might experience with cron are pathing, permissions, and timing. You have to think about how long a script requires to execute and produce output before scheduling another process that depends on it. Referring back to the dmesg script, you can see that you need to know how long the dmesg command requires to finish processing and writing to the dmesg.txt file before scheduling the next command, which is to email the dmesg.txt file to yourself.

Wrapping up

Typically, the way system administrators and other users automate processes on a Linux system is to create scripts that perform functions such as creating files, moving files, emailing information, performing backups, reporting on backups, etc. When you schedule those same scripts in cron, you’ve created true automation on your system. There are very few repetitive tasks that cannot be automated using cron and scripts. If you experience problems with automating tasks that require passwords or interactive sessions, use expect scripts to automate those. If you don’t know expect, watch Enable Sysadmin for future posts on the topic.

There are other ways to automate things in Linux in addition to cron. For example, the at command can be used to run a job at a specific time. You can also set tasks to run at specific times by using systemd, though the systemd timers system.

Free Up Space on Ubuntu

By Bob L | September 7, 2019

Let’s say you need to free up some space on Ubuntu — how do you go about it?

Unlike Windows, with its built-in defrag and disk clean-up tools, Ubuntu doesn’t make it immediately obvious how you go about trying to free up space.

What do you do once you’ve emptied the trash, and deleted those .ISO downloads? How do you recover more space?

We’re going to show you 5 super simple (and in some cases blindingly obvious if easily forgotten) steps you can take to get back those GBs, materialise more MBs, and clean out the stale KBs.

Whenever you need more space — and heck, even if you don’t — here are 5 simple ways to free up disk space on Ubuntu. 

1. Clean the APT Cache (And Do It Regularly)

It sounds so obvious, and yet chances are you haven’t done this.

By default Ubuntu keeps every update it downloads and installs in a cache on your disk, just in case you ever need it again.

This is useful if you regularly add and remove apps, find yourself needing to reconfigure/reinstall a specific package, or simply have a poor connection.

But the flip side is that the apt package cache can quickly swell to several hundred MBs. This command tells you how big your apt cache is:

du -sh /var/cache/apt/archives

To clean the apt cache on Ubuntu simply run the following command.

sudo apt-get clean

The apt clean command removes ALL packages kept in the apt cache, regardless of age or need. If you’re on a slow, capped or intermittent connection you may want to consider skipping this step.

2. Remove Old Kernels (If No Longer Required)

remove old kernels

Now, admittedly, this step is one you want to approach with caution.

Having a choice of kernels to boot up is, honestly, quite handy, especially if you notice something has gone awry while using the latest one.

Unless you’re in the throes of constant hardware woes there’s little need to hoard kernels.

It’s easy to remove old kernels in Ubuntu. You can do it from the command line using the following command:

sudo apt-get autoremove --purge

Note that this command will only remove kernels that a) are no longer needed and b) were installed from the Ubuntu archive through system updates. If you install kernels manually or through a third-party PPA you’ll need to get your hands dirty.

3. Uninstall Apps & Games You Never Use (And Be Honest!)

Chances are you have a number of apps installed that you never use. Maybe you installed them on the back of an awesome review, out of nosiness, or to handle a particular task.

Whatever the excuse, if an app is no longer needed, but more space is, don’t be afraid to uninstall it.

Typical apps you may wish to expunge include web browsers (are you ever going to use Opera, Epiphany, Midori and Min?), music players (heck knows there’s enough of ’em) and games that sounded good in the Steam Store description but ended up being as much fun as a Windows 10 update combo.

And everyone has LibreOffce Draw knocking about doing nothing!

Don’t lie to yourself about might-needs, and could-dos. The beauty of most software is that it’s not going anywhere anytime soon. This is never truer than on Linux, where most apps are just an apt install command away.

To remove a specific app by name run:

sudo apt-get remove package-name1 package-name2

To remove packages and dependencies that are no longer required (because you’ve uninstalled other packages or newer versions have replaced them) run the following command:

sudo apt-get autoremove

4. Use A System Cleaner like BleachBit

Screen Shot 2016-08-09 at 16.09.32

Writing a list on system cleaning could easily end up 10x as long as this one if we were to tell you about every app, cache, log and system process hiding in every nook and cranny.

BleachBit saves us from doing that. It’s like the CCleaner of Linux – a byte scouring beast. The app can remove pretty much everything and anything and should only ever be used with caution.

It can wipe the caches of more than 70 popular desktop applications (including most web browsers); hoovers up old file, browser and bash history; and makes light work of logs you’ll never read.

No surprise that we recommend installing it as one of our things to do after installing Ubuntu.

You can install BleachBit on Ubuntu 16.04 LTS straight from Ubuntu Software. Run it as root, and check the boxes besides the parts you’d like to clean. Click ‘Preview’ to get an estimate of how much space they take up, and click “Clean” to remove them.

How to Use Timeshift to Backup and Restore Linux System

July 28, 2018
by Martins D. Okoi
Written by Martins D. Okoi

Timeshift is an open-source system restore tool that creates incremental filesystem snapshots using either of 2 modes: BTRFS snapshots or rsync+hardlinks.

With it, you can schedule backups at multiple levels using filters and the backups can be restored from Live CD/USB or directly from the system while it is running.

The goal of Timeshift is to maintain the history and integrity of your file system files and settings and not to back up your media files or documents. To do that, you will need a different backup app.

What’s the difference between BTRFS mode and RSYNC mode?

BTRFS Mode creates backups using the BTRFS filesystem’s inbuilt features and the snapshots are supported on only systems that have an Ubuntu-type subvolume layout.

RSYNC Mode backups are made using rsync and hard-links and while each snapshot is a full backup that can be browsed using a file manager, all snapshots share common files in order to save disk space.

How to Install Timeshift in Linux

Timeshift is comes pre-installed on Linux Mint. To install it on other Linux distributions such as Ubuntu and its derivatives, enter the terminal commands below.

$ sudo add-apt-repository -y ppa:teejee2008/ppa
$ sudo apt-get update
$ sudo apt-get install timeshift

On Arch Linux, you can install Timeshift using yaourt command as shown.

$ sudo yaourt timeshift

On other Linux distributions such as Fedora, CentOS and RHEL, you can download the Timeshift installer and execute it in your terminal.

$ sudo sh ./timeshift*amd64.run # 64-bit
$ sudo sh ./timeshift*i386.run  # 32-bit

Running Timeshift for the first time will launch a setup wizard and on completion, you will be ready to start creating snapshots.

I advise that you reconfigure the app after completing the setup wizard steps so you will be able to select user directories that you want to include or use filters to specify files that you want the backup process to include or ignore.

You can always change your settings to fit a different backup scheme from the settings tab.

  • Type – select to create snapshots using RSYNC or BTRFS mode.
  • Location – select the memory location to which snapshots will be saved.
  • Schedule – select how often you want to create snapshots and how many of each category to keep.
  • Users – where you can enable user home directory backups since they are disabled by default.
  • Filters – where you can select files and directories to exclude from snapshots.

Creating & Restoring Backups Using Timeshift

Creating backups is as simple as clicking on the Create button and Timeshift will create a system snapshot using your configured settings.

Remember that using Timeshift, requires you to have a sufficient amount of memory to hold at least 1 snapshot. You can reduce the number of backup levels to as little as 1 by unchecking the backup levels to keep only one selected.

You can reduce the snapshots count in the Schedule tab and set the snapshot number to 5 or less. You can also disable automatic backups and create snapshots manually whenever you need one done.
