Hi!

Can anyone please help me to make my MAC be randomly generated after each reboot?

I need some kind of script or instructions. Thanks you!

Found this one:

#!/bin/sh

INSTALL_PATH="/etc/init.d/randomize_mac"

echo "Creating MAC randomizer script..."
cat << 'EOF' > $INSTALL_PATH
#!/bin/sh /etc/rc.common

START=99

start() {
    generate_random_mac() {
        echo $(printf '%02x' $((RANDOM%256)))":"$(printf '%02x' $((RANDOM%256)))":"$(printf '%02x' $((RANDOM%256)))":"$(printf '%02x' $((RANDOM%256)))":"$(printf '%02x' $((RANDOM%256)))":"$(printf '%02x' $((RANDOM%256)))
    }

    change_mac() {
        local iface=$1
        local new_mac=$(generate_random_mac)
        ip link set dev $iface down
        ip link set dev $iface address $new_mac
        ip link set dev $iface up
    }

    for iface in $(ip link show | grep -E '^[0-9]+:' | cut -d ':' -f 2 | cut -d ' ' -f 2); do
        if [ "$iface" != "lo" ]; then
            change_mac $iface
        fi
    done
}
EOF

echo "Making MAC randomizer script executable..."
chmod +x $INSTALL_PATH
echo "Success!"

echo "Enabling MAC randomizer script to run at boot time..."
/etc/init.d/randomize_mac enable
echo "Success!"

echo "Deleting installation script..."
rm -- "$0"

Here is example of output of this command:

echo $(printf '%02x' $((RANDOM%256)))":"$(printf '%02x' $((RANDOM%256)))":"$(printf '%02x' $((RANDOM%256)))":"$(printf '%02x' $((RANDOM%256)))":"$(printf '%02x' $((RANDOM%256)))":"$(printf '%02x' $((RANDOM%256)))

Output:

a7:03:f2:fa:45:5d

I need to make my router Admin panel be accessible not by HTTPS and block HTTP.

I am using Mudi v2

Chat gpt prompted to generate custom CA:

#!/bin/sh
openssl genrsa -out ca.key 4096
openssl req -new -x509 -days 36500 -key ca.key -out ca.crt -subj "/C=XX/ST=XX/L=XX/O=Example/OU=CA/CN=ca.example.lan"
openssl genrsa -out router.lan.key 4096
openssl req -new -key router.lan.key -out router.lan.csr -subj "/C=XX/ST=XX/L=XX/O=Example/OU=Devices/CN=router.lan"
openssl x509 -req -days 36500 -in router.lan.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out router.lan.crt
echo "CA and signed router.lan certificate generated in current directory"

It will generate certificates and key. What to do next?
