314
Summary
- // typical exposure
- Internal-only — Opalis Robot is a legacy Windows job-automation agent meant to operate within a managed enterprise network, not to accept public-internet connections; the product has been discontinued since its 2011 rebrand to System Center Orchestrator and no legitimate use case requires internet exposure.
- // analyst note
- an open 314/tcp is very rare and most likely a stale remnant of an end-of-life Windows automation product rather than active infrastructure; verify host role before assuming malicious intent.
- // if you see it open
- No known CVEs, malware, or trojan associations found across GRC Port Authority, AuditMyPC, and SpeedGuide. The port does not appear in Wikipedia's well-known-ports table, consistent with an obscure/legacy registration rather than an actively scanned or discussed port. Live scan-prevalence was not checked, so current real-world rarity is Unknown.
About port 314/tcp.
Port 314/tcp (dual-registered with 314/udp) is IANA's opalis-robot entry for Opalis Robot, the agent/listener component of a legacy Windows job-scheduling and IT-process-automation product; it has no legitimate reason to be reachable from the public internet and belongs strictly inside a managed internal network.
The IANA registry lists the service name as opalis-robot, description "Opalis Robot," with Laurent Domenech as both assignee and contact. No registration date and no RFC/reference are recorded in the registry for this entry — both are left blank here rather than invented.
Opalis Robot dates to 1995 and handled distributed job execution, event monitoring, and corrective-action automation across managed Windows servers. Microsoft acquired Opalis Software Inc. in December 2009 and rebranded the line as System Center Orchestrator in March 2011, shipping it as part of System Center 2012; the last release under the original name was Opalis Integration Server 6.3. Port 314 is a legacy identifier from before the acquisition, and vendor documentation for the Microsoft-era Orchestrator product does not reference it.
No CVEs, malware, or trojan associations turned up for port 314 across the sources checked, and it does not appear in Wikipedia's curated well-known-ports table — consistent with an obscure, largely retired registration rather than an actively scanned or discussed port. No live scan-prevalence dataset (Shodan/Censys/nmap-services) was consulted, so current real-world rarity is Unknown rather than confirmed.

Primary use
Opalis Robot agent — Windows IT process-automation/job-scheduling software, first released 1995 [Likely] — https://archive.org/details/tucows_314726_OpalisRobot, https://www.networkworld.com/article/696018/infrastructure-management-chapter-1-introducing-opalis-integration-server-6-3.html
Security implications
no known CVEs or malware associations found; absent from Wikipedia's well-known-ports table, consistent with obscure/legacy status
Typically seen on
legacy pre-2011 Opalis Robot / Opalis Integration Server deployments; unexpected today given the product's discontinuation [Likely]
- Software lineage

About port 314/udp.
Port 314/udp carries Opalis Robot, a proprietary IT process (run-book) automation client/server messaging channel from Opalis Software; it belongs strictly on internal enterprise networks rather than the public internet, since the protocol has no public-facing purpose and the underlying product line is largely obsolete.
IANA registers 314/udp as opalis-robot, description "Opalis Robot," assignee/contact Laurent Domenech. No RFC or other reference document is cited, and the registry's rendered table does not expose a per-entry assignment date, so that field is left Unknown rather than invented. 314/tcp carries an identical dual registration under the same service name, assignee, and contact, with all other columns blank.
Opalis Robot was the original tool from Opalis Software Inc., a leading independent IT Process Automation vendor; it was already superseded within Opalis's own product line by Opalis Integration Server starting with OIS 5.0 in October 2005. Microsoft announced its acquisition of Opalis on 2009-12-11, and the technology was folded into Microsoft System Center as System Center Orchestrator, making 314/udp traffic reflect a pre-2010, largely retired enterprise tool rather than actively maintained software.
