* Decouple LDS and server clients in ClientFindServersThomas Vanbesien3 days1-44/+135
| | | | | | | | | | | | | Create two independent UA_Client instances in client_find_servers.c: one for LDS discovery calls (FindServers, GetEndpoints) and one for server session calls (readServerTime). This allows different security modes, policies, auth, and trust lists for the LDS vs discovered servers. Config keys are now prefixed: discovery* for LDS connection settings, server* for discovered server settings. All config files updated accordingly with split trust lists (discoveryTrustList for LDS cert, serverTrustList for server cert).
* Add comments to build files and shell scripts, fix minor inconsistenciesThomas Vanbesien3 days2-3/+4
| | | | | | | | | | | | | - CMakeLists.txt: add file-level comment, section banners, target docs, and test-section explanation - cmake/BuildDeps.cmake: add file-level comment describing the configure/build/install workflow - tools/generate_certificate.sh: document arguments and outputs in header block, comment set -euo pipefail - src/config.h: move include guard before Doxygen block (match common.h) - src/server_register.c: add comment to empty anonymous-auth block (match client_find_servers.c)
* Add configurable log level as optional CLI argumentThomas Vanbesien3 days5-6/+82
| | | | | | | | | All three programs now accept an optional second argument [log-level] (trace, debug, info, warning, error, fatal) defaulting to info. The level is applied by setting the logger context pointer directly, avoiding a memory leak that would occur from overwriting the heap-allocated logger struct. Also documents the ASan leak-check workflow in CLAUDE.md.
* Replace CLI arguments with config-file parser and add integration testsThomas Vanbesien3 days5-120/+551
| | | | | | | | Introduce a reusable key=value config parser (config.h/c) and convert all three programs to read their settings from config files instead of positional command-line arguments. Add example config files in config/ and 6 CTest integration tests covering None/Basic256Sha256/Aes128 with anonymous and user authentication. Remove the now-obsolete launch.sh.
* Improve comments in server_register.cThomas Vanbesien3 days1-1/+6
| | | | | | Remove a useless comment on an empty branch and add intent comments before the manual event loop startup, the periodic re-registration loop, and the shutdown deregistration block.
* Make authentication mode and credentials configurable via CLIThomas Vanbesien3 days3-43/+197
| | | | | | | | | | | | | Replace hardcoded user/password credentials with a new <auth-mode> parameter that accepts "anonymous" or "user". When "user" is chosen, two additional <username> <password> arguments are required. ServerRegister accepts two independent auth modes: one for its own server-side access control and one for authenticating to the LDS when registering. ClientFindServers passes credentials to readServerTime, which selects UA_Client_connectUsername or UA_Client_connect accordingly. Update CLAUDE.md running examples and add an auth modes table.
* Add username/password authentication to servers and clientThomas Vanbesien3 days3-1/+36
| | | | | | | | | Disallow anonymous sessions on both the LDS and registering server by configuring UA_AccessControl_default with a hardcoded user/password credential pair. Set UA_ClientConfig_setAuthenticationUsername on the client configs used for register, re-register, and deregister calls. Use UA_Client_connectUsername in the FindServers client when reading server time.
* Initial commit: OPC UA discovery projectThomas Vanbesien3 days5-0/+927
CMake-based C project using open62541 for OPC UA discovery. Includes Local Discovery Server, register server, and find servers client with OpenSSL encryption support.
