Could you recommend it, please? I am searching for a job opportunity under Frey's supervision, ideally in a correctional facility. I am not considering paid positions due to the limited customer base and low likelihood of significant growth in the near future.

Do you have any suggestions?

Currently, I have come across Domain Technologies Control (DTC), but it seems impractical and burdened with excessive features (in my humble opinion).

Our recommendation is ISPConfig, which can be installed on FreeBSD even though this is not explicitly stated.

ISPConfig offers numerous localizations, including a third version. Another excellent option to consider is sysCP, a strong control panel that is also compatible with FreeBSD.

Webmin is a free option, while ISPmanager is one that requires payment.

If you're interested in a free panel, Vesta is another solid choice that's worth considering.

BrainyCP, Fastpanel, ISPConfig, Ajenti, and CWP - there are a variety of control panels to choose from when it comes to managing your web server. BrainyCP is a functional control panel that allows webmasters to configure the state control of all or part of the services to choose from. It is multilingual and supports PHP 5.2-7.4.

Fastpanel, another option to consider, has built-in task scheduling, web analytics, two-factor authentication, and support for OpenVZ, KVM, Hyper-V virtualization systems.

ISPConfig is a free and open-source panel that enables the management of multiple virtual and physical machines. The panel provides four levels of access: admin, reseller, client, and e-mail user.

Ajenti, a popular admin panel with open-source and modular structure, uses NGINX instead of Apache.
It also provides fine-tuning of the configuration of the services and applications used.

Lastly, CWP (Control Web Panel) is an open-source and free-to-use panel that includes file management, email management, and many other features. It supports CentOS, RHEL, and CloudLinux.

Considering your preference for unpaid positions, it may be beneficial to explore volunteer opportunities within the correctional system. These roles can provide valuable experience and networking opportunities while aligning with your career goals.

One recommendation would be to reach out to local correctional facilities or organizations that work with incarcerated individuals. Volunteering as a mentor, tutor, or support group facilitator could offer meaningful interaction with the population you aim to serve. Additionally, consider contacting nonprofit organizations focused on criminal justice reform, as they may have volunteer positions available.

In terms of Domain Technologies Control (DTC), if you find it impractical and burdened with excessive features, it's wise to continue your search for a better fit. Consider networking with professionals in the correctional field to seek recommendations for potential opportunities. Building connections through informational interviews and industry events can be a valuable strategy for discovering hidden job openings.
Don't underestimate the value of professional development and continuing education. Enrolling in relevant courses or obtaining certifications related to correctional rehabilitation could enhance your qualifications and make you more competitive in the job market.
