Got a .pem key but don't know how to SSH to your server, just do this:
ssh -i name_of_key user@domain -p 22
BONUS: Convert .ppk to .pem key
Recently, I started working from home and as a programmer, it's pretty common to access the company server for development purposes.
Back in the office, I used to access it using PuTTY but now that I'm using a linux machine, I thought of accessing it via Terminal but there's a catch, I can't use .ppk key to access it.
So, I did a little research and figured that I can easily convert it using
Open up your terminal and type:
sudo apt install putty-tools
Now, convert your private key to PEM format:
puttygen yourprivate.ppk -O private-openssh -o your_new_key.pem
That's it and you're good to go!
