C. SLM Communication
This section uses the example system configuration shown below to explain the port numbers used in SLM communication and the direction in which data passes through a firewall (the direction in which a connection is established).
The person who monitors services uses a browser to connect to SLM - Manager.
SLM - UR is deployed to monitor the Web system services.
Communication between SLM - Manager and the browser
Communication between SLM - Manager and the browser is as follows:
Port number of the browser
Pass-through direction
Communication protocol
Port number of SLM - Manager (HTTP server)
(ANY)/tcp
HTTP
20900/tcp (httpsd)
Communication between SLM - Manager and SLM - UR
Communication between SLM - Manager and SLM - UR is as follows:
Port number of SLM - Manager
Pass-through direction
Communication protocol
Port number of SLM - UR
(ANY)/tcp
RMI
20910/tcp (jslmuRMI)
(ANY)/tcp
RMI
(ANY)/tcp
20904/tcp (jslmmRMI)
RMI
(ANY)/tcp
(ANY)/tcp
RMI
(ANY)/tcp
In addition to these communications, the following communications are also available:
- Communications using ports in the range from 20901/tcp to 20904/tcp on the local host on which SLM - Manager is running
- Communications using port 20910/tcp on the local host on which SLM - UR is running
-
Collection of HTTP packets by SLM - UR
Set up the firewall so that SLM - UR can obtain HTTP packets that were copied by the port mirroring function.
To specify a program to allow communication, specify settings on the host where SLM - UR was set up so that communication of the following program is allowed:
-
SLM-UR-installation-folder\ur\system\sdp\bin\sdppcap.exe
-
