Our worksite inside Newark Liberty International Airport (EWR) is suffering repeated network drop-outs that disrupt daily operations. I need an experienced IT technician who can come on-site, trace the root cause of the connectivity issues, and get every device reliably back online right away. Here is what the visit will involve: • Diagnose the physical and logical network path from ISP hand-off through our switch rack and out to several workstations and VoIP phones. • Identify and correct cabling, switch, router, or configuration faults responsible for the disconnections. • Validate stability once fixes are applied and supply a brief post-visit report outlining what you found and how you resolved it. You should be comfortable working around standard enterprise gear (...

Preciso resolver falhas recorrentes na rede do meu ambiente de trabalho e quero contar com um técnico de T.I. especializado em manutenção de rede. O foco principal é diagnosticar a causa raiz dos problemas de conectividade e desempenho, apresentar a solução e aplicá-la de forma eficiente. Escopo do trabalho • Levantar rapidamente o estado atual da infraestrutura (cabeamento, switches, roteadores, pontos de acesso e configurações). • Executar diagnóstico detalhado, documentando sintomas, causas prováveis e testes realizados. • Entregar um relatório claro com a causa raiz e o plano de correção. • Implementar as correções aprovadas, validar com novos teste...

I’m rolling out an OpenNMS deployment focused on fault management and would like an experienced consultant to help us with the design, and (remotely) assist with the rollout. Scope and current environment • Devices in scope: servers, routers/switches, plus a growing fleet of IP cameras that must raise actionable alarms when connectivity or video streams fail. What I need from you – A review of the planned OpenNMS architecture, scaling approach, and high-availability options. – Best-practice configuration snippets for alarms, notifications, and automatic remediation. – Guidance on integrating non-traditional devices (like some IP cameras) so fault data is both accurate and meaningful. – Knowledge-transfer sessions (screen-share or recorded) tha...

I need a working SIP-edge on an Ubuntu 22 / 24 VM that lets MicroSIP register over TLS even in networks where standard SIP/VoIP traffic is blocked. The edge will terminate the TLS leg, proxy the signalling to my existing VoIP switch over plain UDP, and keep media flowing through RTP Engine. What I will provide • A clean VM (public IP, sudo access) • SIP account details for registration tests • Any public cert/key material you need for stunnel or Kamailio TLS Scope of work – Install and configure Kamailio as the front-end SIP proxy. – Enable TLS support so MicroSIP can register and place calls securely. – Use RTP Engine to anchor media and make sure audio is two-way. – Deploy stunnel (or an equivalent TLS wrapper) if it...

Over the past few days my Grafana + Prometheus stack has begun to churn far more CPU than usual, the web UI feels sluggish, and the graphs occasionally show empty gaps. I need a seasoned Grafana / Prometheus troubleshooter to dig in, pinpoint the bottleneck, and restore smooth, complete monitoring. Here is what I am after: • Diagnose and eliminate the recent CPU spike on the Grafana server (Ubuntu, Prometheus scraping multiple node-exporters). • Find out why some series disappear briefly and correct the root cause—whether that is scrape errors, query load, retention settings, or anything else you uncover. • Build a clean, focused dashboard that shows only the essentials I care about: CPU usage, Memory usage, Disk usage, Uptime, Bandwidth In/Out, and Network Speed...

I have a requirement at a client site and need an experienced network engineer who can be on-site, diagnose the issue, restore full connectivity and be out the door within the agreed 4–8 hour window. Your own laptop and standard tool kit are required, and you should be completely comfortable working solo with routers, TCP/IP, DHCP, DNS and general LAN/WAN fundamentals. On arrival you will meet the local contact, isolate the fault on the router, apply the necessary fix or configuration change, verify that traffic is flowing correctly and then document what you did. Because the job is time-critical I’m looking for someone who can commit to an ASAP visit and stick to the same-day service-level agreement. Deliverables I expect from you before you leave the site: • Restore...
