Focus areas • Network security: packet sniffing, basic exploitation, lateral movement, and network-level hardening. • Social engineering: phishing set-ups, pretexting scenarios, and the defense playbook that counters them. Learning format We will work inside pre-configured virtual machines you supply, where you walk me through the build-break-fix cycle: launching a representative attack, detecting it with common tools (Wireshark...

I’d like my Windows laptop configured so my children (aged 10-15) can use it safely without constant supervision. The setup must: • Enforce daily and weekly time limits that automatically log them out when the allowance is reached. • Block a list of questionable or distracting websites I will provide, and make it easy for me to add or remove sites later. • Prevent access to specific applications and system areas I choose, while leaving school-related programs untouched. • Let me trigger a remote log-off or shutdown from my own account or phone whenever homework needs attention. I don’t have a preferred tool yet and would appreciate your guidance on whether the built-in Windows family settings are enough or if a third-party suite (e.g. Qustodio, Norto...

Our stack runs on a mix of Proxmox VMs, bare-metal Linux, and Docker containers that host several resource-intensive workloads (WordPress sites, small AI services, internal tools). Performance has started lagging, so the goal is a measurable speed-up across the board—CPU, memory, disk I/O, and network throughput. Scope of the optimisation • Server side: fine-tune Proxmox (kernel parameters, storage back-ends, CPU pinning) and harden the underlying Linux hosts, making sure Docker containers inherit those gains. • Network side: analyse current routing, bridges, VLANs and SDN overlays, then remove bottlenecks and reduce latency between VMs, containers and external clients. • Application side: profile the heaviest WordPress and AI containers, tweak PHP-FPM, databas...

I need somebody who can jump in right away and sort out an Indian-based digital service that refuses to activate. The platform’s portal shows my order as active, yet nothing actually works on the device side—so the core problem is exactly what you’d label “Service not working.” I have already completed payment and received all the standard confirmation messages, but calls to the provider’s helpline keep routing me through the same scripted checks without results. I’m hoping you can step beyond that and identify what is blocking the activation, then implement or guide me through the correct fix—whether that involves backend account tweaks, firmware commands, APN details, or any other practical step you know works in India’s infrastruc...

I an experienced penetration tester to web application. The primary objective is to identify vulnerabilities, with particular attention paid to three high-risk zones: • Authentication and authorization logic • Database exposure paths (SQL injection, insecure queries, weak configuration) • Input validation and handling that could open the door to XSS, command injection, or similar issues I will provide you with staging and live URLs, test accounts, and any required API keys. Please treat the exercise as a real-world black/grey-box engagement—no source code will be shared. You may use industry-standard tooling such as Burp Suite, OWASP ZAP, sqlmap, or custom scripts as you see fit, as long as methodology aligns with the OWASP Testing Guide.

I have a fresh install of the Vibe server application running as a VoIP bandwidth optimizer and I’m stuck at the configuration stage. My immediate goal is to finish the initial setup, fine-tune the optimizer settings, and then bring a VoIP gateway online on a public IP so calls flow end-to-end without drops or quality loss. A screenshot of the current network layout is attached for reference. Here’s what I need: • Apply the right Vibe configuration parameters so it actually starts shaping traffic efficiently. • Map the public IP, open the correct SIP/RTP ports, and register the gateway so it’s reachable from outside the LAN. • Walk me through any CLI or web-GUI steps I’ll need to repeat later (firewall rules, NAT, codec or QoS tweaks). •...

I need a thorough, external-facing penetration test focused on my network infrastructure. The environment is small—fewer than 50 devices—and the critical assets are the servers that host internal services and data. No web or mobile application testing is required; this engagement is strictly about identifying and safely exploiting weaknesses on the network layer. Here is what I expect from you: • A concise test plan outlining scope, methodology, and tooling before any scanning begins. • Active reconnaissance and exploitation against the server segment, using industry-standard tools such as Nmap, Nessus/OpenVAS, Metasploit or similar. • A clear, prioritized vulnerability report that includes technical details, business impact, and actionable remediation step...
