Hi

I will soon need to hire a Linux system administrator for my hosting project.

I would be happy to share more details about the project with you - it is currently running, but I plan to migrate to some new systems (e.g. new admin panel, etc.). In addition, a security audit will need to be performed.

The operating system will also need to be reinstalled due to security concerns related to previous administrators.

If you have solid experience in this area, I would be happy to discuss further details.

Please note that we will also need to place a strong emphasis on the security of the hosting environment.

I also want to emphasize the quick communication between us. It means a lot to me!
Because before we start work, I will have many questions and methods to discuss, and accordingly, the faster it is answered, the more trust we will create.
Thank you

I am currently seeking a highly skilled and experienced freelancer to assist in the migration of my existing dedicated Ubuntu server at Hetzner to a new dedicated server environment.

I'm having security issues sometimes with this current server and do not want to face them in the new server. I'm open to recommendations and also need some clean up work like removing unnecessary services and apps etc.

This is a critical task that requires a thorough understanding of server management, application migration, and security protocols, as it involves transferring all current web applications (less than 10), databases, and configurations to the new server with efficiency and precision.

The successful candidate will be responsible for a variety of tasks, including, but not limited to, the following:

1. Comprehensive Assessment: Conduct a detailed assessment of the current server environment, including all web applications, databases, and any associated services. I'll also help you to understand what is needed for me.

2. Transfer Plan: Create a brief transfer plan for me. I'll review and approve it. This will ensure that we both do not spend unnecessary time on the project and understand each other.

3. Data Transfer: Execute the transfer of all web applications, ensuring that data integrity is maintained throughout the process. This includes migrating databases, application files, and any necessary configurations to the new server.

4. Security Setup: Implement robust security measures on the new server to protect against potential vulnerabilities. This may include configuring firewalls, setting up SSL certificates, and ensuring that all applications are updated to the latest security standards. Also please configure user management for me. I am mostly using root user in my current server and I think that causes some security problems.

5. Testing and Validation: After the migration is complete, conduct thorough testing to validate that all applications are functioning correctly on the new server. This includes checking for any discrepancies in data, performance issues, or configuration errors.

6. Guidance and Support: Provide ongoing guidance and support throughout the entire migration process. This includes being available to answer questions, address concerns, and troubleshoot any issues that may arise. I'll ask some questions but not make you uncomfortable by asking too much.

Please share your availability and estimated time for the project as well.
