Scp in linux and ssh key usage

Today, the O & M Department provides a testing environment for virtual machines. they all use public keys for logon. it is easier to use keys in windows, but the transmission between virtual machines and virtual machines is troublesome. I have to use my local machine for transit. It is found that scp has a parameter-I which can load the public key. This is convenient, but an error occurs during execution.

 

Today, the O & M Department provides a testing environment for virtual machines. they all use public keys for logon. it is easier to use keys in windows, but the transmission between virtual machines and virtual machines is troublesome. I have to use my local machine for transit.

It is found that scp has a parameter-I which can load the public key, which is more convenient.

However, an error occurs during execution.

 

Root @ localhost :~ # Scp-I shopex_bakserver.bakserver otp_src_R14B03.tar.gz 1.1.1.1:/root/

@ WARNING: unprotected private key file! @

Permissions 0644 for 'shopex _ bakserver. bakserver' are too open.

It is recommended that your private key files are NOT accessible by others.

This private key will be ignored.

Bad permissions: ignore key: shopex_bakserver.bakserver

Permission denied (publickey ).

Lost connection

This error occurs mainly because the public key has too many permissions. you can reduce the permission to 600.

Chmod 600 shopex_bakserver.bakserver
