Cisco 7960 for Freepbx 15

Hello. I am looking for a mentor in Linux. I have experience as a strong junior DevOps specialist, but Linux and Kubernetes are my weak points. While I have some project experience with Kubernetes, my interaction with Linux is very superficial. Creating something, adding, renaming, opening, etc. is clearly not enough. I need a mentor who can help me improve in this area. The main task is to ensure that the knowledge sticks in my head, possibly through some pet project, tasks, or something along those lines, rather than just "repeat after me." I have taken courses on my own, but they don't particularly "stick" in my head. Here is a rough list of what I think I need: - Linux/Unix systems — in-depth administration of operating systems, file systems, user and access rights management, processes and services (systemd), Bash scripting, logging, monitoring, security configuration, automation of administrative tasks; - Networking technologies — OSI model and TCP/IP stack, DNS, HTTP/HTTPS, SSL/TLS, SSH, VPN, load balancing, proxy servers, NAT, routing, network utilities (ping, traceroute, netstat, ss, tcpdump, curl), diagnosing and troubleshooting network issues; If Kubernetes can be added to this list, that would be great. Perhaps you can suggest something from your side. The format of the sessions, as I see it, is twice a week, meetings, discussions, consultations. More details can be your ideas and suggestions. Regarding the cost per hour or per month - please propose.

Unfortunately, during the process of updating the website code (hereinafter - deployment), there may be a loss of information from the database, i.e., deletion of some records from individual tables. The idea of the database integrity control mechanism is to create a service that can be called from the Admin panel with two functions: Fix the state of the database immediately before deployment. Control the compliance of the database before and after deployment. The integrity of the database consists of the integrity of all tables in this database. The state of a table is defined by 1 parameter: "Number of records in the table." A table after deployment is considered intact if the state parameters of the table Before and After match. A complete task statement will be provided directly to the contractor of the order. This is an interesting project https://derzn.ru/drevo/, but this is a NON-COMMERCIAL project. The payment is, in some sense, symbolic. However, you will gain good experience in solving real, complex tasks and receive positive feedback for well-done work. You will enhance your portfolio and order history here.
