Sobre o Ubuntu

Para começar a atualização do Ubuntu do sistema, primeiro precisamos atualizar a lista de índice de pacotes. Abra o terminal e digite:

sudo apt update

Podemos instalar a atualização para todos os pacotes de uma só vez: A forma a seguir vai atualizar todas as versões dos pacotes instalados, sem remover pacotes.

sudo apt upgrade

Tudo feito. Seu sistema Ubuntu agora está totalmente atualizado.

Durante a atualização inicial do sistema, alguns dos pacotes podem se tornar obsoletos e, portanto, não são mais necessários. Para remover todos os pacotes desnecessários, execute:

sudo apt autoremove

Para analise do Kernel

dmesg

Para analise da Bios

sudo dmidecode -t bios

UFW ( Uncomplicated Firewall ) é um firewall padrão no Ubuntu 18.04 Bionic Beaver Linux.

Por padrão, o UFW está desativado. Você pode verificar o status do seu firewall executando o seguinte comando:

sudo ufw status

Para habilitar a execução do firewall:

sudo ufw enable

ou melhor ainda

mysqladmin -u root -p -i 1 processlist

Recursively fix bad file permissions

A common suggestion is to use which means:

755 for directories: full control for the user, and everyone else can traverse directories.

644 for files: read-write permissions for the user, and read-only for everyone else.
