Create a Samba share on Fedora

- by Pupli 
sudo dnf install samba
sudo systemctl enable smb --now
firewall-cmd --get-active-zones
sudo firewall-cmd --permanent --zone=FedoraWorkstation --add-service=samba
sudo firewall-cmd --reload

Samba does not use the operating system users for authentication, so your user account must be duplicated in Samba. So if your account is jane on the host, the user jane must also be added to Samba. While the usernames must match, the passwords can be different.

sudo smbpasswd -a jane

mkdir /home/jane/share
sudo semanage fcontext --add --type "samba_share_t" ~/share
sudo restorecon -R ~/share
sudo nano /etc/samba/smb.conf
[share]
        comment = My Share
        path = /home/jane/share
        writeable = yes
        browseable = yes
        public = yes
        create mask = 0644
        directory mask = 0755
        write list = user
sudo systemctl restart smb

Disable SELinux if required

sudo nano /etc/selinux/config

SELINUX=disabled

sudo reboot

Trust the ASP.NET Core HTTPS development certificate on Fedora

- by Pupli 
sudo dnf install nss-tools

Setup Firefox

echo 'pref("general.config.filename", "firefox.cfg");
pref("general.config.obscure_value", 0);' > ./autoconfig.js

echo '//Enable policies.json
lockPref("browser.policies.perUserDir", false);' > firefox.cfg

echo "{
    \"policies\": {
        \"Certificates\": {
            \"Install\": [
            	\"aspnetcore-localhost-https.crt\"
            ]
        }
    }
}" > policies.json

dotnet dev-certs https -ep localhost.crt --format PEM

sudo mv autoconfig.js /usr/lib64/firefox/
sudo mv firefox.cfg /usr/lib64/firefox/
sudo mv policies.json /usr/lib64/firefox/distribution/
mkdir -p ~/.mozilla/certificates
cp localhost.crt ~/.mozilla/certificates/aspnetcore-localhost-https.crt

Trust Edge/Chrome

certutil -d sql:$HOME/.pki/nssdb -A -t "P,," -n localhost -i ./localhost.crt
certutil -d sql:$HOME/.pki/nssdb -A -t "C,," -n localhost -i ./localhost.crt
