Proper file permissions in place on Host guarantee that each standard user (without sudo privileges) that you create on Host will own their /home/new_user directory but have limited permissions with the rest of the directory structure.
Type: `ssh Standard User Accounts on Host with limited file permissions outside their home folder. Port: port number specified in Host's sshd_config file. To open an SFTP shell terminal as on Host, open a Terminal on Client and enter the following command, replacing 123.123.1.23 with Host's IP address: sftp you changed the port number Host's OpenSSH server listens to, do: sftp -P open an SSH shell terminal as on Host, open a Terminal on Client and enter the following command, replacing 123.123.1.23 with Host's IP address: ssh you changed the port number Host's OpenSSH server listens to, do: ssh -p to Host and login via GUI file manager (e.g., Nautilus) for more visual SFTP access to enable file transfers See Configure OpenSSH server and router to accept SSH connection over internet?Ĭonnect to Host and login via command-line or terminal 
Typically, you can point your web browser to 192.168.1.1 in order to login to your router and setup port forwarding.Note the port Host's ssh service listens to in the sshd_config file and setup your router to forward TCP/UDP traffic aimed at this port to the IP address of your OpenSSH server. If you need access from anywhere over the internet, Setup Port Forwarding on your local router to direct traffic to your OpenSSH server Save your new sshd_config file and then restart Host's ssh service: sudo service ssh restart If you feel you must, Enable PasswordAuthentication in your sshd_config fileįind the line with the phrase PasswordAuthentication and make it read: PasswordAuthentication yes For more ideas, see Keeping SSH Access Secure.
#Sftp openssh install
Slow attackers' cracking attempts: Use ufw (uncomplicated firewall) on Host to rate limit incoming connections to 10/minute: sudo apt-get install ufw & sudo ufw limit OpenSSH. 
Then add PasswordAuthentication no to to Host's /etc/ssh/sshd_config
Allow only RSA key (passwordless) connections: Append the contents of ~/.ssh/id_rsa.pub from each Client as a new line of Host's ~/.ssh/authorized_keys. Allow certain users on certain ports: Add AllowUsers or AllowUsers to Host's /etc/ssh/sshd_config. Allow only local connections: Add ListenAddress 192.168.0.10. Choose non-standard SSH port: Comment out Port 22 add Port to Host's /etc/ssh/sshd_config. Disable root login: Comment out PermitRootLogin without-password add PermitRootLogin no to Host's /etc/ssh/sshd_config. Don't enable port-forwarding on your router: When outsider asks your router to connect outsider to Port 22, etc., your router fails to comply unless you have enabled port-forwarding. You must restart your ssh service on Host for these changes to take effect sudo service ssh restart "Once you've backed up your sshd_config file, you can make changes with any text editor, for example:" sudo -H gedit /etc/ssh/sshd_config Sudo chmod a-w /etc/ssh/sshd_config.factory-defaults To configure your OpenSSH server, "first, make a backup of your sshd_config file by copying it to your home directory, or by making a read-only copy in /etc/ssh by doing:" sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.factory-defaults Give your Host a Static IP address so you can reliably connect to it: nm-connection-editor To install an OpenSSH server on Host: sudo apt-get install openssh-server 
Install and configure your OpenSSH Server on Host Administrative User Accounts created on Host will have sudo privileges, Standard User Accounts created on Host will not.
#Sftp openssh password
"Make sure you have a strong password before installing an SSH server (you may want to disable passwords altogether)" Note, however, that public key authentication is recommended, On Ubuntu you can setup an OpenSSH server on a Host machine and a user can then use ssh to connect from Client to Host's server using only a username and password.This will allow you to use SSH File Transfer Protocol (also Secure File Transfer Protocol, or SFTP) to access, transfer, and manage files over SSH from a Client machine. The best resource to help you begin setting up an ssh service on a Host machine using Ubuntu is OpenSSH Server.
