    Open Source ICTFax software setup

    ยืนยันแล้ว

    I need an open-source ICTFax on my linux server so I can both send and receive faxes from the network. Every incoming fax must be archived automatically as a PDF, and all administration—including queue monitoring, user setup, and log review—has to be handled through a clean, browser-based interface. Any stack that meets those points is fine Like ICTFax as long as it runs on a recent Debian/Ubuntu or CentOS release with no licensing fees. I will supply SSH access to a fresh VM and either a Class 1/2 USB modem or a T.38 SIP trunk you can register against.

    I need an IPRN switch brought online fast, fully wired for billing integration and ready to carry live traffic. The core signalling will run over SIP, so every module you build or configure must interoperate cleanly with SIP endpoints and the upstream carrier trunks I already have in place. Billing is the priority: once a call lands on the switch the CDRs must flow straight into our existing rating platform without manual touches. I am open to whether you plug in a ready-made mediation layer or write custom logic—what matters is that usage records appear in real time and reconcile correctly at the end of each day.

    I’m running Base44 on a Plesk-hosted VPS and want every embroidery file a user uploads to instantly generate a PNG preview that shows up right inside the app. The obvious path seems to be wiring Embroidermodder (libembroidery command-line tools) into the server, but I’m open to any cleaner or lighter-weight method you might propose—as long as it’s fully automated and stable. Scope of what must work – Accepted upload formats: DST, PES and EXP. – As soon as an upload completes, a server-side routine should convert it to a PNG. – The resulting PNG is stored and immediately rendered back to the user in the existing “view” area of Base44 (no download links or e-mails; the preview lives in the app UI). – Solution must fit smoot...

    I need a secure, lightweight VPN application built for both and Android. The interface can stay minimal; stability, speed, and protocol flexibility are the real priorities. Core capabilities I expect: • Kill switch that reliably blocks traffic if the tunnel drops • Split tunneling so the user can choose which apps bypass the VPN • Support for the following protocols or transport layers: ssh, ssl, udp, v2ray, and websocket • A menu of multiple server locations that I can expand later through simple JSON or similar remote config No in-app user-authentication flow is required; the build should assume pre-provisioned profiles or embedded credentials. Deliverables: 1. Clean, well-commented source code (/Kotlin or Java/) 2. Signed release builds ready for TestFli...

    We are getting multiple OT projects and need more hands to support us in terms of this. I’m consolidating several Industry-grade PCs that run bespoke Python applications into our existing Operational Technology environment. The immediate goal is to create a clean, well-documented integration pathway that lets these machines exchange data safely with the rest of the plant network while respecting every cyber-security control already in place. Here’s what I’ll hand over on day one: current network maps, the Python sources, and a short list of approved protocols (mainly Modbus/RTU). From you I need a streamlined integration plan, the actual Python interface code or refactor, and clear documentation that anyone on the OT team can follow without hunting for tribal knowledge....

    I’m bringing my health-focused website up to full HIPAA compliance and need an experienced security professional to handle the technical hardening. The immediate priorities are: • Provision and correctly install an SSL certificate so every page, asset and sub-domain loads exclusively over HTTPS. • Encrypt all stored and transmitted medical-record data, making sure keys are managed securely and database backups follow the same standard. • Review the current codebase, server configuration and third-party plugins against HIPAA’s Security Rule, then patch any gaps you find. • Document the changes and supply a simple compliance checklist I can keep on file for auditors. I’m on a Linux VPS running Nginx with a Laravel backend; you’re free to us...

    YOLO CCTV Theft & Customer Analytics
    4 วัน left
    ยืนยันแล้ว

    I want a single, turnkey application that watches my CCTV feeds, spots shop-lifters in real time, recognises grocery products on the shelves, and keeps a live head-count of customers. The core model must be YOLO, and I need the exact same code-base to compile and run on both Windows (desktop with NVIDIA GPU) and a Raspberry Pi 4. Video sources vary—some cameras stream RTSP over IP while a few older analog units reach the NVR through a capture card—so the program has to accept either type without manual re-configuration. For product recognition I care only about groceries; no clothing or electronics labelling is necessary. The model should be trained (or fine-tuned) on the most common supermarket items so false positives stay low even when shelves are crowded. Key expecta...

    I have already created the subdomain of my main domain where will live and I can give you full SSH/root access to the Linux server that powers it (Ubuntu 24.04 with HestiaCP panel running on port 8083 of main domain). Subdomain has ssl via Let's encrypt. All I need is a clean, production-ready installation of the latest stable release, configured so it loads flawlessly from the subdomain (HTTPS, reverse proxy, environment variables, database, etc.). I have a VPS hosted by Hostinger. You are free to use the official Docker set-up or a manual Node.js build—whichever you feel is most reliable—but please secure it properly, connect it to a Postgres database (which has to be setup as well), and leave me with concise notes so I can maintain or upgrade it later.

    I have a fresh Ubuntu 22.04 VPS ready and I want a fully working Open Tibia server running version 13.x or newer. I am happy to go with either Canary or TFS—whichever you feel will get us to a stable, live server fastest. My own attempts stalled mainly at the client-connection stage, so the critical piece for me is having at least one client (official Tibia or OTClient, I am flexible) connect reliably to the server once it is online. What I need from you: • Compile or install the chosen engine on the VPS, configure it, and verify it boots without errors. • Walk me through the minimal config changes so I understand what was done. • Provide a working client package—or clear instructions for obtaining and patching one—that logs straight into the serve...

    I’m looking for an online tutor based in India who can guide me through intermediate-level administration of both Linux and Windows Server environments. On the Linux side I want practical, session-based coaching in system administration, security and firewall management, and shell scripting.

Each topic needs to be demonstrated live, with time for me to replicate the steps on my own lab machines during or immediately after the call. We can meet on Zoom or Google Meet for 2–3 hours a week, preferably evenings or weekends. Deliverables • A structured lesson plan that maps out the sequence of sessions • Recordings or sess...

    I need to link one incoming GSM leg with a SIP participant inside FreeSWITCH so both callers join the same live conference room without noticing any difference in media or signaling. The end result must feel like a single, seamless conversation. Key requirements • FreeSWITCH must act as the bridge and mixer. • The conference room has to support call recording (start automatically and save to disk) and allow me to mute or un-mute either participant from the console or an API. Current environment – A working GSM gateway already delivers calls to FreeSWITCH through SIP. – An existing SIP trunk is in place for the VoIP side. – Root access to the FreeSWITCH server is available.

    Fix Hotmail Block on cPanel IP

    Emails sent from my cPanel-hosted domain have suddenly stopped landing in Hotmail / Outlook inboxes. There is no listing on public black-hole services and Microsoft support insists the IP is not formally blocked, yet every message to @hotmail, @outlook and @live addresses is silently dropped. Key context • The mail is generated by the default cPanel mail service (Exim). • No recent changes were made to DNS, SPF, DKIM, rDNS or server configuration. • My only troubleshooting so far has been opening a ticket with Microsoft; the response pointed me to general guidelines without lifting the block. What I need – A thorough diagnosis of why Microsoft is filtering or throttling the IP. – Remediation steps applied (SPF / DKIM / DMARC alignment, rDNS, HELO bann...

    Harden Lenovo T480 with Debian

    I have a Lenovo ThinkPad T480 waiting for a fresh, security-first Debian installation. The goal is a fully hardened, privacy-respecting daily-driver that ships with BOTH Mozilla Firefox and Brave, each pre-tuned for strong tracking-protection and fingerprint-resistance. This is an ADVANCED hardening job. Beyond the base install I’ll need full-disk LUKS2 encryption, secure boot/Libreboot if the hardware permits, locked-down BIOS settings, kernel and sysctl tweaks, AppArmor (or comparable MAC), DNS proxy with encrypted queries, and a firewall configured to best practice levels. I did not select a specific firewall in the form, so feel free to recommend whether UFW, iptables or firewalld is the right fit for an always-on laptop that roams between trusted and untrusted networks.
