    Enter the password when prompted and enter Y to continue with the installation.
  2. Once the installation is completed, the SSH service will start automatically. To verify that the installation was successful and SSH service is running type the following command which will print the SSH server status:
    sudo systemctl status ssh
    You should see something like Active: active (running) :
    Press q to get back to the command line prompt.
  3. Ubuntu comes with a firewall configuration tool called UFW. If the firewall is enabled on your system, make sure to open the SSH port:
    sudo ufw allow ssh
Now that SSH is installed and running on your Ubuntu system you can connect to it via SSH from any remote machine. Linux and macOS systems have SSH clients installed by default. If you want to connect from a Windows machine then you can use an SSH client such as PuTTY.

Installing and Configuring TFTP Server on Ubuntu 5 months ago by  Shahriar Shovon TFTP (Trivial File Transfer Protocol) is a simplified version of FTP (File Transfer Protocol). It was designed to be easy and simple. TFTP leaves out many authentication features of FTP and it runs on UDP port 69. As it is very lightweight, it is still used for different purposes. TFTP is used in places where you don’t need much security. Instead, you need a way to easily upload files to and download files from the server. CISCO devices use TFTP protocol to store configuration files and CISCO IOS images for backup purposes. The network boot protocols such as BOOTP, PXE etc uses TFTP to boot operating systems over the network. Thin clients also use TFTP protocol for booting operating systems. Many electronics circuit boards, microprocessors also use TFTP to download firmware into the chip. Overall, TFTP has many uses even today. In this article, I am going to show you how to install and conf

instalar .bundle en linux

En primer lugar  abrimos una ventana de terminal y asignamos privilegios de root con el comando sudo su . Ahora  nos ubicamos en la carpeta donde hemos descargado el archivo de instalación  gracias al comando CD, en mi caso sería así: cd /home/maxi/Descargas/ Cuando ya estamos en la carpeta y tenemos localizado el archivo vamos a proceder a  aplicar permisos de ejecución sobre el mismo . Para ello escribimos; chmod 777 nombrearchivo.bundle chmod +X nombrearchivo.bundle Ahora solo nos queda  ejecutar el programa de instalación , para ello escribimos en el terminal lo siguiente: ./archivo.bundle

CHMOD +x , 755 , explicacion

Explanation: Firstly you should know that: +  means add this permission to the other permissions that the file already has. =  means ignore all permissions, set them exactly as I provide. So all of the "read, write, execute, sticky bit, suid and guid" will be ignored and only the ones provided will be set. read = 4, write = 2, execute = 1 Here is the binary logic behind it (if you're interested): Symbolic: r-- -w- --x | 421 Binary: 100 010 001 | ------- Decimal: 4 2 1 | 000 = 0 | 001 = 1 Symbolic: rwx r-x r-x | 010 = 2 Binary: 111 101 101 | 011 = 3 Decimal: 7 5 5 | 100 = 4 / / / | 101 = 5 Owner ---/ / / | 110 = 6 Group ------/ / | 111 = 7 Others ---------/ | Binary to Octal chart Using  +x  you are telling to add ( + ) the executable bit ( x ) to the owner, group and others. it's equal to  ugo+x  or  u+x,g+x,o+x When you don't specify
