A clear and concise description of the issue.

Running the LXC Updater and notice I get this error on a few LXC's. Specifically ones that have the names with Capital Letters

Which Linux distribution are you employing?

Debian 12

How is this a script issue? Use valid hostnames!

[MoldyTaint]

I did not assume the issue was with your scripts, I assumed that if I could use hostnames with a capital letter and not have it error out for the container it was fine. They have been running fine until I attempted the updating script. I was not aware that having a capital letter was that big of an issue nor did I think that Proxmox would allow the capital letters if it would cause such issues in genral.

This was not to upset or demean your scripts, they have worked wonders for my needs as clearly I don't have the capabilities to make anything as nice. It was a question and a potential problem that I thought I recognized(on my end) but was not sure on.

Here is an explanation that highlights its significance.

Using valid hostnames is important for several reasons in the context of computer networking and the internet:

1. Identification and Accessibility: Valid hostnames provide a human-readable way to identify and access networked resources. Instead of remembering IP addresses (e.g., 192.168.1.1), which can be difficult to recall and error-prone, users can access resources using meaningful names (e.g., www.example.com).

2. Ease of Management: Valid hostnames make it easier to manage and maintain networked systems. System administrators can use hostnames to identify and configure devices and services, simplifying network management tasks.

3. Scalability: Valid hostnames are essential for scalable network architectures. As networks grow and new devices or services are added, hostnames make it easier to integrate them into the existing infrastructure without requiring significant changes.

4. Fault Tolerance: Hostnames can be associated with multiple IP addresses or have backup servers, providing fault tolerance. If one server goes down, the hostname can be configured to automatically switch to another available server, minimizing downtime.

5. Security: Valid hostnames are important for security purposes. They can be used in access control lists (ACLs) and firewall rules to restrict or allow access to specific resources based on their names. This helps protect against unauthorized access and potential security breaches.

6. Email and Web Services: Valid hostnames are crucial for email and web services. They are used to route email messages and web requests to the correct servers. Without valid hostnames, email delivery and web browsing would be much more challenging.

7. Caching and DNS: Valid hostnames are essential for the Domain Name System (DNS), which translates human-readable hostnames into IP addresses. DNS caching relies on the accuracy of hostnames to reduce the load on DNS servers and improve response times.

8. Compliance and Standards: Many networking standards and protocols, such as HTTP, SMTP, and SNMP, require the use of valid hostnames for proper functioning. Non-compliant hostnames may cause interoperability issues with other systems and services.

In summary, using valid hostnames is essential for efficient and reliable network operations, accessibility, scalability, security, and compliance with networking standards. They simplify network management, improve fault tolerance, and enhance the overall user experience on the internet and local networks.

Thank you for the detailed explanation, while admittedly I still don't fully comprehend the lower/uppercase issue as much I fully respect and appreciate the follow up with all the importance.

Thank you again
