I have a Hikrobot ID3000 industrial scanner hooked up to my network over Ethernet. The Windows PC it should talk to already has the official Hikrobot drivers and software installed, yet the device never appears in the utility—so it’s almost certainly an IP or subnet mismatch. I’ll open a remote-control session (TeamViewer, AnyDesk or similar) so you can jump straight onto the machine, adjust the network settings, and prove the scanner is reachable. Once the scanner shows up and a quick test read succeeds, the job is done. Acceptance criteria: • Hikrobot discovery tool lists the scanner without manual refresh tricks • A live barcode read streams correctly into the PC application • All changes documented so I can replicate them later

I need an experienced FRITZ!Box/IPSec VPN specialist to set up a rock-solid IPSec tunnel between my FRITZ!Box router and a CentOS-based VPS for secure remote access to my home network from anywhere. Current setup: FRITZ!Box connected through a 4G USB modem/mobile provider Dynamic public IP on the FRITZ!Box modem side VPS with root access and a clean CentOS installation Preferred VPN stack: strongSwan (or equivalent if justified) Scope of work: Configure a stable fritzbox-to-site IPSec tunnel between the FRITZ!Box and the VPS

I am looking to purchase or acquire 100 GB of pro-level ethical hacking training materials specifically focused on network analysis with all attacks tutorial . The primary interest is in high-quality eBooks that provide in-depth learning within this niche. If you have collections or access to such resources that align with professional-level training, please get in touch with details about the content and how it addresses network analysis.

I’m putting together a full-scale enterprise network for our organisation and need someone who can take the project from initial design through to a live, well-documented deployment. The brief is intentionally open because I want your expertise to guide the decisions on architecture, hardware brands (Cisco, Juniper, Aruba, Fortinet, etc.), routing protocols, redundancy, and security hardening. Here’s how I picture the engagement: • High-level and detailed network design that follows best practices for scalability, resilience, and segmentation • Configuration templates or scripts ready to drop into switches, routers, firewalls, and wireless controllers • Step-by-step implementation plan with a rollback strategy • Post-deployment testing results plus c...

I’m looking for a tech-savvy professional who can diagnose and resolve the slow internet speeds on my network. The issue isn’t a full outage—pages eventually load, but streaming, video calls, and large downloads crawl. I’ve confirmed the problem persists across multiple devices, so it appears to be network-wide. Here’s what I need from you: • Run a structured troubleshooting session via remote tools (e.g., Zoom, TeamViewer, or your preferred platform). • Review my modem and router settings, firmware version, and channel/bandwidth configuration. • Guide me through speed tests and analyze the results to pinpoint bottlenecks—ISP, hardware, cabling, or Wi-Fi congestion. • Recommend and implement fixes: optimal DNS settings, QoS twe...

I have a Cisco router that now boots straight into ROMmon. I’m on the console port and can interrupt the sequence, but the primary IOS image appears to be corrupted or missing. I need guidance to load a clean image, return the router to normal operation, and preserve the existing startup-config. What I need from you: • Exact ROMmon commands and sequence to transfer or locate a working IOS image (TFTP, USB, or XMODEM—whichever you recommend). • Steps to confirm the startup-config is still intact and will automatically load after the fix. • Precautionary actions so the configuration is not lost during flash cleanup or image replacement. • If necessary, instructions to capture a backup of the running or startup configuration over the console before any r...

I need a working U.S.–based SIP trunk that plugs straight into my existing 3CX PBX, and I need it online immediately. This is for a live business system, so downtime is not an option. Here’s what I am expecting from you: • Provide a fully-provisioned SIP route (inbound and outbound) that registers successfully with 3CX and passes test calls. • Supply clear configuration details—host, authentication, codecs supported, 911 compliance, and any DID options—so I can import them quickly. • Hand over written step-by-step instructions or a short screen-share session for final cut-over. Please respond only if you can deliver right away. Include a detailed proposal outlining the solution you will supply, how you will integrate with 3CX, and your est...
