How to install Broadcom WiFi drivers in Fedora 27

Install RPM Fusion

sudo dnf install$(rpm -E %fedora).noarch.rpm$(rpm -E %fedora).noarch.rpm

Install packages

sudo dnf install -y kernel-devel-$(uname -r)

Install Hashcat on Fedora

Install nVidia drivers.  Guide here.

Download binary files from the hashcat website

or use wget


Extract with p7zip

7z x hashcat-

cd into the hashcat directory

cd hashcat-4.1.0

Run hashcat

./hashcat64.bin -t 32 -a 7 example0.hash ?a?a?a?a example.dict

Example script:

sudo dnf install p7zip
7z x hashcat-
cd hashcat-4.1.0

Install SSH Server on Linux (Debian, Ubuntu, Fedora, CentOS, RedHat)

Debian / Ubuntu

sudo apt-get install -y openssh-server

RPM based Distros, Fedora / CentOS / RedHat

sudo dnf install -y openssh-server

or use yum

sudo yum install -y openssh-server

Start ssh service

sudo systemctl start sshd

By default the SSH service should start when the system starts, but if not try the following command to enable the service on boot up.

Debian / Ubuntu

systemctl enable ssh

Fedora, CentOS, RedHat

systemctl enable ssh

Change SSH port

Not necessary, but it is a good idea to change the default ssh port.  To change the port edit the sshd file.

How to set a static ip address on CentOS, Fedora, or Red Hat Linux

Open up the following file with your favorite text editor. Change eth0 to the interface you need, like “wlan0” or “eth1”.

 vi /etc/sysconfig/network-scripts/ifcfg-eth0

The file should look something like the following.


To set the static IP address change “BOOTPROTO=dhcp” to “BOOTPROTO=static” and add the following to the end of the file. If you want/need the interface to come up when the computer boots up then be sure to change “ONBOOT=no” to “ONBOOT=yes”.


So your file should now look like this.


Save the file and restart networking.

service network restart

Finally, check you IP address with ifconfig.

root@localhost ~]# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 0A:2G:F3:56:66:4B  
          inet addr:  Bcast:  Mask:


How To Make a Live Bootable Fedora Thumb Drive in Linux

Insert your thumb drive into the computer.

We need to find out where the thumb drive is mounted.  We can do this with the “df” command as shown below or you can find it in dmesg.

So if we run the df command

df -h

It returns something like this

[me@fedora ~]$ df -h
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/fedora-root   50G   11G   37G  23% /
devtmpfs                 1.9G     0  1.9G   0% /dev
tmpfs                    1.9G  1.2M  1.9G   1% /dev/shm
tmpfs                    1.9G  1.1M  1.9G   1% /run
tmpfs                    1.9G     0  1.9G   0% /sys/fs/cgroup
tmpfs                    1.9G   52K  1.9G   1% /tmp
/dev/sdb1                477M  115M  333M  26% /boot
/dev/mapper/fedora-home  176G  125G   42G  75% /home
/dev/sdc1                3.8G  3.2G  592M  85% /run/media/me/136A-7360
[me@fedora ~]$

Note that the bottom one is the thumb drive /dev/sdc1 yours may differ.

Now that we know where the drive is mounted we can write the image to the thumb drive.

Change the path in “if=/” to the path to your Fedora iso and change “of=/” to you thumb drive path

su -c "dd if=/home/me/Downloads/Fedora-Live-x86_64-20-1.iso of=/dev/sdc bs=8M"

It will take a couple of minutes to complete and it will not give you any information until it is finished.

Congratulations, you now have a live working Fedora thumb drive.

How to Install Flash on Linux

Installing flash on Ubuntu is pretty straight forward.  Type the following command into a terminal and press enter and away you go.

sudo apt-get install flashplugin-installer

On Fedora need to do the following


sudo yum install -y


sudo yum install -y

And install the Adobe Flash web browser plugin.  The first command imports the GPG key for the Adobe Flash plugin repository and the second command installs the plugin itself.

sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux 
sudo yum install flash-plugin -y
