One of my clients provided me .ppk file to connect to his server using ssh. As I am a Ubuntu user, I need a key which can be used the terminal command. So I decided it convert to .pem file. I am sharing the steps to convert ppk to pem format on Linux terminal using putty gen tool.
Step 1 – First of all, install the putty tools on your Linux system using below command.$ sudo apt-get install putty-tools
Step 2 – Now, convert the ppk file to pem file using puttygen command line tool.$ puttygen server1.ppk -O private-openssh -o server1.pem
Step 3 – Change the .pem file permissions. Set the read-only permissions to the owner of the file, remove any permission to group and other. Other wise ssh will refuse this key for use.$ chmod 400 server1.pem
Step 4 – Finally, connect to your remote Linux server with ssh using this pem key.$ ssh -i server1.pem [email protected]
