Data Networking/Fall 2014/Priya/Web Server - openSSH-server & client configuration
Appearance
1. Web Server - openSSH-server
To install openSSH-server and generate public and private keys, do the following steps
sudo apt-get install openssh-server sudo nano /etc/ssh/sshd_config
- Change port to 555 (or other port that suits your flavor)
Port 555
- Modify the following lines to permit the server and client to communicate using the public keys
RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys PasswordAuthentication no
- Create .ssh directory and generate ssh keys
mkdir ~/.ssh chmod 700 ~/.ssh chown $USER:$USER ~/.ssh ssh-keygen -t rsa
2. Remote Client - openSSH-client
To install openSSH-client and generate its private and public keys, do the following steps
sudo apt-get instal openssh-client
sudo nano /etc/ssh/sshd_config
- Modify the following lines to permit the server and client to communicate using the public keys
RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys PasswordAuthentication no
- Create .ssh directory and generate ssh keys
mkdir ~/.ssh chmod 700 ~/.ssh chown $USER:$USER ~/.ssh ssh-keygen -t rsa
- Copy the public key from client to server
sudo scp /home/kuldeep/id_rsa.pub peterkelada@x.x.x.x:/home/peterkelada ssh-add
Finally, after successfully installing and configuring openSSH on both server and client, you can access the server at port 555 using the following command
sudo ssh -p 555 peterkelada@x.x.x.x
