Cowrie was exposing an SSH daemon on port 22 alongside the telnet service
even when COWRIE_SSH_ENABLED=false, contaminating deployments that did not
request an SSH service.
New implementation mirrors the SSH service pattern:
- busybox telnetd in foreground mode on port 23
- /bin/login for real PAM authentication (brute-force attempts logged)
- rsyslog RFC 5424 bridge piped to stdout for Docker log capture
- Configurable root password and hostname via env vars
- No Cowrie dependency
- HTTP: configurable server_header, response_code, fake_app presets
(apache/nginx/wordpress/phpmyadmin/iis), extra_headers, custom_body,
static files directory mount
- SSH/Cowrie: configurable kernel_version, hardware_platform, ssh_banner,
and users/passwords via COWRIE_USERDB_ENTRIES; switched to build mode
so cowrie.cfg.j2 persona fields and userdb.txt generation work
- SMTP: configurable banner and MTA hostname
- MySQL: configurable version string in protocol greeting
- Redis: configurable redis_version and os string in INFO response
- BYOS: [custom-*] INI sections define bring-your-own Docker services
- Stealth: rename all *_honeypot.py → server.py; replace HONEYPOT_NAME
env var with NODE_NAME across all 22+ service templates and plugins;
strip "honeypot" from all in-container file content
- Config: DeckyConfig.service_config dict; INI [decky-N.svc] subsections;
composer passes service_cfg to compose_fragment
- 350 tests passing (100%)
