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 that supports the terminal command. So I decided it convert to .pem file. I am sharing the steps to convert PPK to Pem format on the Linux terminal using a 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. Otherwise 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]
