Definition: The '731-mark-postfix.conf' in English refers to a specific configuration file used by some web servers, primarily on Amazon Web Services (AWS) instances. This file stores information about the server's security settings for user access control purposes.
The 'mark-postfix' is often used to mark certain types of IP addresses as secured by AWS, allowing users to have more control over their internet traffic and potentially avoid unauthorized access.
In AWS, each instance has a unique 'mark-postfix' set which contains the rules regarding which IPs are marked with "731" (or "marked") and which ones aren't.
The 'mark-postfix.conf' file is typically located in /etc/ssl/certs and would have several lines of configuration:
- The line "mark-postfix = 731:80:" specifies the IP address to mark as secured.
- The line "cert-authority-data = cert-authorities.pem" contains a list of trusted certificate authorities.
- The line "key-store-password = secret-key.pem" is used for securely storing the key used for signing certificates.
The 'mark-postfix.conf' file can have many other lines that define additional security settings or user restrictions.
The main use cases are to set up secure connections between the server and AWS instances, to limit access based on IP addresses (e.g., using a "marked" label), or to allow certain types of content to be accessed only by authenticated users.
For detailed definitions:
- 'mark-postfix' is an AWS security feature used for securing specific IP addresses. It is represented as a string in the server configuration file, often with '731:80:' at the beginning and 'cert-authority-data=cert-authorities.pem'.
- 'cert-authority-data' is another part of the configuration file that specifies which certificate authorities to use. This line is usually followed by "key-store-password=secret-key.pem".
- The key used for signing certificates can be securely stored in a file called 'cert-authorities.pem'. This is typically done using AWS CLI tools or in a server's root console.
- When accessing the server, it will look like this:
```
mark-postfix = 731:80:
cert-authority-data = cert-authorities.pem
key-store-password = secret-key.pem
```
It should be noted that these settings are typically managed by AWS and can vary depending on specific server configuration.
In summary, the 'mark-postfix' is a security feature in AWS to mark certain IP addresses as secured. The key is used for securely storing the key used for signing certificates.
