ssh and pem file
I've 2 nodes, and I can only contact them with ssh using a pem file.
(It doesn't work)
ssh -i ~/key.pem user@host
1 - If the pem file contains a private key, why it's important to access a remote host with ssh?
2 - Is it possible to replace the pem key file to a way that I can access the remote host without referring the pem file?
the file is a preshared key. In general, you should probably just read up about what a preshared key is for. Basically it's an alternative authentication mechanism to using a password.
Yeah... and, I gotta say, you really wanna be using cryptographic certificates, instead! ... and disabling all other "lesser" forms of authentication.
