SSH Directory Permissions Settings

It is important to set the directory and file permissions for your ~/.ssh correctly.

Typically you want the permissions to be:

• .ssh directory: 700 (drwx——)
• public key (.pub file): 644 (-rw-r–r–)
• private key (id_rsa): 600 (-rw——-)
• lastly your home directory should not be writeable by the group or others (at most 755 (drwxr-xr-x)).

For example, to set this permissions do: $ chmod 700 ~/.ssh $ chmod 600 ~/.ssh/* $ chmod 644 ~/.ssh/*.pub $ ls -ltr ~/.ssh/
