inc_cipher_aes256.cl: No such file or directory
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 sshd
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.
vi /etc/ssh/sshd_config
If you change the port, you’ll need to allow it in the firewall (firewalld, iptables) and if SELinux is enabled, semanage.
Problem: Volume goes from mute to 100% with very little ability to adjust it.
The following command should work on any Linux computer that is running alsa.
alsactl initInstall kernel headers, dkms, etc
dnf -y kernel-headers kernel-devel dkms gcc gcc-c++
Reboot the VM
reboot
Mount the Guest Additions by going to menu > Devices > Insert Guest Additions CD image… or you can hit “Host + D”.
The Host key is typically the Right Ctrl(On Windows) or CMD(On OS X) key.
Via the GUI
Mount the Guest Additions from your file browser, and then launch the “VBoxLinuxAdditions.run”.
You will need root privileges, so either launch your file browser as root, or drag and drop the “VBoxLinuxAdditions.run”, into a root terminal and hit Enter.
Via Command Line
mkdir /tmp/vbox sudo mount /dev/cdrom /tmp/vbox sudo /tmp/vbox/VBoxLinuxAdditions.run
If you run into any errors, try ejecting, and remounting the Guest Additions cd.
Run the following commands as root
rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm rpm -Uvh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
Update the system and then download the driver.
yum update yum install kmod-wl
When the above commands finish reboot the computer
reboot
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.
DEVICE=eth0 HWADDR=0A:2G:F3:56:66:4B TYPE=Ethernet UUID=aeh9421c-6a62-712c-886d-347813g8d1dh ONBOOT=no NM_CONTROLLED=yes BOOTPROTO=dhcp
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”.
BROADCAST=192.168.1.255 DNS1=8.8.8.8 GATEWAY=192.168.1.1 IPADDR=192.168.1.110 NETMASK=255.255.255.0
Also, on some newer versions of CentOS you may need to add NM_DISABLED=no
So your file should now look like this.
DEVICE=eth0 HWADDR=0A:2G:F3:56:66:4B TYPE=Ethernet UUID=aeh9421c-6a62-712c-886d-347813g8d1dh ONBOOT=yes NM_CONTROLLED=no BOOTPROTO=static BROADCAST=192.168.1.255 DNS1=8.8.8.8 GATEWAY=192.168.1.1 IPADDR=192.168.1.110 NETMASK=255.255.255.0
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:192.168.1.110 Bcast:192.168.1.255 Mask:255.255.255.0
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.
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
(64-bit)
sudo yum install http://linuxdownload.adobe.com/adobe-release/adobe-release-x86_64-1.0-1.noarch.rpm -y
(32-bit)
sudo yum install http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm -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
1. Open a terminal and change to the root user
su -
2. Then cd into the following directory
cd /etc/yum.repos.d/
3. Install wget.
yum install wget
4. Download the repo files with wget.
wget http://download.virtualbox.org/virtualbox/rpm/fedora/virtualbox.repo
5. Install the dependencies.
yum install binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms
6. Update your computer.
yum update
7. Install VirtualBox.
yum install VirtualBox-4.2
8. Add the VirtualBox user to the vboxusers group
usermod -a -G vboxusers user_name
9. Reboot your computer.
reboot
10. Enjoy. If you run into problems try the following.
/etc/init.d/vboxdrv setup
Note:
I have created a script that will do all this for you, download here. All you need to do is the following 3 commands.
cd /pathto/fedora-vb-installer.sh chmod +x fedora-vb-installer.sh sudo ./fedora-vb-installer.sh
