Guidance on usage: SFTP – OpenSSH FTP Server on Ubuntu 20.04 Minimal

Configuration and connection to the SFTP – OpenSSH FTP Server on Ubuntu 20.04 Minimal

Connecting and managing server

  1. Run the VM through Azure Portal. To customize the Server, first, you need to know the server IP address. You can find it in the personal account of Azure. (You need to select the virtual machine from the list. By clicking the item “Overview”, your IP is displayed in the line “Public IP Address”).
  1. To work, you should open port 22  in the network properties in the Azure firewall.
  1. To manage with a server you should connect to a VM.
    1. With OpenSSH

In the Windows 10 operating system (starting with version 1809 ), an OpenSSH client is available, with which you can connect to Linux servers via SSH. If Windows 10 is suitable and the OpenSSH client is installed, you can start connecting via SSH. To do this, launch a normal Windows command prompt and enter the command ” ssh user@*vm_ip*”. 

Where “user” is the username that was specified while creating the virtual machine and “*vm_ip*” is the VM IP address.

In the opened console it is necessary to enter a password that was specified while creating the virtual machine.

  1. With the PuTTy application 

To do this you need the PuTTy application to connect via ssh. You can download it at the following link – Download

Run Putty, enter the VM address in the “Host” field, and click “Open” to connect.

In the opened console you will need to enter a username and password that were specified while the VM was being created (you’ll not see the password in the console while entering it).
