Real Linux deployments (especially Ubuntu cloud images) ship a non-
root admin user; honeypots that only accept root logins are a tell.
Add a second account on both SSH and Telnet decoys, configurable
via service_cfg keys `user` / `user_password`, defaulting to
`ubuntu` / `admin` so the lure is live on every fresh deploy.
* `decnet/services/{ssh,telnet}.py` — two new ServiceConfigFields
(`user` string, `user_password` secret) and matching env vars
(`SSH_USER` / `SSH_USER_PASSWORD`, mirror for telnet) propagated
via the compose fragment.
* `decnet/templates/ssh/entrypoint.sh` — runtime `useradd -m -s
/usr/libexec/login-session -G sudo "$SSH_USER"` so the new user
inherits the same sessrec pty-recording shell as root and lands
in the sudo group. Privesc attempts (`sudo`) flow through the
existing sudo-log capture; network-enum from the user's shell
rides the recorded transcript.
* `decnet/templates/telnet/entrypoint.sh` — same useradd pattern
(no sudo group — busybox+login telnet image has no sudo
package; privesc rides `su -` which itself flows through the
existing PAM auth-helper at /etc/pam.d/login).
* New tests for default + custom user / password + independence
from root password. Updated the schema-keys assertion to match
the four-field shape.
The new account is ALSO the natural home for the body-aware
predicates that were previously gated on root-only sessions —
attackers who land on `ubuntu@host` and run network-recon /
privesc commands now generate the same structured TTP-rule
events as root sessions did, captured via the same auth-helper
+ sessrec + sudo-log pipes.
ServiceConfigField dataclass + BaseService.validate_cfg coerce/drop submitted
service_cfg dicts against per-service typed schemas. SSH/HTTP/HTTPS now declare
the keys they already read in compose_fragment, so the upcoming Inspector form
has metadata to render from instead of hardcoded inputs per service.
real_ssh was a separate service name pointing to the same template and
behaviour as ssh. Merged them: ssh is now the single real-OpenSSH service.
- Rename templates/real_ssh/ → templates/ssh/
- Remove decnet/services/real_ssh.py
- Deaddeck archetype updated: services=["ssh"]
- Merge test_real_ssh.py into test_ssh.py (includes deaddeck + logging tests)
- Drop decnet.services.real_ssh from test_build module list
Scraps the Cowrie emulation layer. The real_ssh template now runs a
genuine sshd backed by a three-layer logging stack forwarded to stdout
as RFC 5424 for the DECNET collector:
auth,authpriv.* → rsyslogd → named pipe → stdout (logins/failures)
user.* → rsyslogd → named pipe → stdout (PROMPT_COMMAND cmds)
sudo syslog=auth → rsyslogd → named pipe → stdout (privilege escalation)
sudo logfile → /var/log/sudo.log (local backup with I/O)
The ssh.py service plugin now points to templates/real_ssh and drops all
COWRIE_* / NODE_NAME env vars, sharing the same compose fragment shape as
real_ssh.py.
- 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%)
