Ports in censhare environments
All ports must be TCP and are configured by default as mentioned below.
censhare Java clients
all Java-based clients, for example censhare Client, Admin Client, Render Client
1099 (RMI) and 30543-30545 (RMI highports) or
30546-30548 (RMI highport over SSL)
You can also specify a port directly, such as SSL, only with port 30546.
For this, add the port to the RMI URL within your hosts.xml:
url="rmis://<hostname/fqdn>:30546/corpus.RMIServerSSL"
In this case, only port 30546 will be used.
Configure fixed port for connections from censhare Server to censhare Render Client.
By default, the censhare Render Client binds to a random higher port. How to configure a fixed port is described here.
Application server to database
1521 (JDBC) for Oracle database
- 5432 for Postgres database
Access to censhare 5 Web
- 9000 (http) and 9443 (https)
As of censhare v5.8, http is not allowed anymore and will be deactivated by default.
As censhare 5 Web uses a build-in Jetty web server which also serves the REST interface and temporary download link, these ports are valid for those services, too.
censhare built-in FTP server
4242 for FTP: not exposed to the Internet
for FTPs (passive FTP):
- 4243 is the command port
- 4244-4349 is the data port range

censhare ports diagrams
The diagrams below provide a rough overview of which ports are used and by which components. However, keep in mind that:
- those are not architecture diagrams; for architecture overview, please consult this page
- different network setups are possible and depend on your specific requirements
Therefore, the visualizations below are given for reference but should not be treated as direct instructions.
