Connecting to linux server form ubuntu using .ppk file

Make sure you have installed:

sudo apt-get install openssh-server openssh-client

Install putty using:
sudo apt-get install putty

Generate rsa keys and place them in your .ssh folder.

• Create the public key file:
  puttygen /path/to/puttykey.ppk -L > ~/.ssh/id_rsa.pub
• Create the private key file:
  puttygen /path/to/puttykey.ppk -O private-openssh -o ~/.ssh/id_rsa

Now you are able to ssh and scp to that server.

If you have .pem file and want to convert it into .ppk file use the below:

puttygen ec2-democrasoft.pem -O private -o ec2-democrasoft.ppk


AFAIK, the files under .ssh show have below permissions.



-rwx------ 1 root root 1675 2011-03-31 12:31 id_rsa
-rw-r--r-- 1 root root  402 2011-03-31 12:31 id_rsa.pub
