    <h1 align='center'>MiniDLNA Arch Linux</h1>

    DLNA (Digital Living Network Aliance), is collection of interoperability guidelines which set the protocols for multimedia communication

    ## install minidlna
    ```
    sudo pacman -S minidlna
    ```

    ## configure minidlna
    ```
    port=8200
    network_interface=wlp4s0
    user=<user>
    media_dir=/home/<user>/Videos/
    db_dir=/home/<user>/.local/share/minidlna/cache
    log_dir=/home/<user>/.local/share/minidlna/log
    enable_subtitles=yes
    ```

    ## create necessary folders
    ```
    mkdir -p $XDG_DATA_HOME/minidlna/{cache, log}
    sudo mkdir /run/minidlna
    sudo chown <user>:<group> /run/minidlna
    ```
    * cache stores the sqlite db, and `/run/minidlna` contains the pid file
    * permissions are important as we are changing the user as well

    ## configure firewall rules
    ```
    # nft add rule <family> <table> <chain>
    sudo nft add rule inet filter input [position 1] tcp dport 8200 accept comment trivnet1
    sudo nft add rule inet filter input [position 1] udp dport 1900 accept comment ssdp
    ```
    * positions are optional arguments here, depending on the ruleset of the firewall but essentially it has to be before this line:
    ```
    meta pkttype host limit rate 5/second counter reject with icmpx admin-prohibited
    ```
    * if errors persist just temporarily remove the entire ruleset like so `sudo nft flush ruleset`

    ## change runtime user
    ```
    sudo systemctl edit minidlna.service
    ```
    ```
    # write the following in between the instructed lines on override.conf
    [Service]
    ProtectHome=off
    User=<user>
    Group=<group>
    ```

    ## start minidlna
    ```
    sudo systemctl start minidlna
    ```

    ## verify the service
    ```
    http://<ip of media server>:8200
    ```
