Configure
The only thing now a little setup.
Hostname
First bit of system administration might be to set the hostname, for example:
Then, notice with this version of Python the version of Fedora, good to go:
Great!
VSCode
I user PyCharm and VSCode, but VSCode does seem to be the most popular editor, it's free after all and has great plugins for just about everything.
See this for installation: https://code.visualstudio.com/docs/setup/linux
Here are the important steps for Fedora:
sudo sh -c 'echo -e "[code]\nname=Visual Studio Code\nbaseurl=https://packages.microsoft.com/yumrepos/vscode\nenabled=1\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc" > /etc/yum.repos.d/vscode.repo'
Using the package manager mean any updates will come through along with any operating system updates running dnf update -y, job done.
SSH Key
Always opt for using SSH keys for authentication over username and passwords, it's more secure (providing you keep your private key private), and simplifies automation.
If you stand up an Alma Linux server as explained in the next section, you can copy your public key to it, for example:
You'll be asked to confirm the fingerprint, and be promoted for the target users password to add you key, in this case root:
The authenticity of host '192.168.122.202 (192.168.122.202)' can't be established.
ED25519 key fingerprint is SHA256:8/osIaA7AfEoM/Ljg9wpPBgXRxpU9UXcVKwSM+xNXF0.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@192.168.122.202's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'root@192.168.122.202'"
and check to make sure that only the key(s) you wanted were added.
With this in place, you can then log into the server with ssh root@192.168.122.202, and not get prompted for a password.
Default Editor
In recent releases of Fedora they have change the default editor to nano which I hate. To put back vi:
Local DNS
A fine nice trick is to edit your /etc/hosts file and use friendly host names. Linux hosts will always look in this file prior to any other DNS resolution.
Now you can use:
Sudoers
Finally, if you get tired of entering your password everytime you use sudo on the commandline, edit sudoers and change the line %wheel ALL=(ALL) ALL to:
SSHD
On Fedora the SSHD daemon is disabled. If you wish to SSH to the Fedora VM from another host (such as your laptop when using a virtual machine):
