C HP SIM Dynamic Ports
There are three main processes in HP SIM:
• mxdomainmgr
• mxdtf
• mxinventory
These processes communicate with each other using Secure RMI connections (TCP).
HP SIM does not use any specific port. It uses anonymous ports based on the underlying Java RMI
implementation which uses the User ports (for example, 1024 – 49151 on Microsoft Vista, Microsoft
2008 and above operating systems). HP SIM processes use different ports on every restart.
• Though Java RMI is used on various user ports, HP SIM listens only on “localhost” such that
these services are not exposed outside the system running HP SIM, for consumption. These
ranges can be safely blocked in a firewall configuration for incoming requests from outside
hosts.
• The mxdtf process listener port can be configured in the configuration file, mx.properties,
by setting MX_PORT to the appropriate value. However, if this value is missing, HP SIM defaults
to 2367.
• In addition to inter-process communication, these processes perform their regular activities,
for example data collection using SNMP / WBEM / SSH etc. from a managed node. Under
these situations, the processes use any of the dynamic ports (both TCP and UDP), for outgoing
connections.
HP SIM uses various user ports in the range of 1024 to 65535 (using TCP and or UDP) for
inter-process communication among the various HPSIM processes. This range of ports can be safely
blocked in a firewall configuration for incoming requests from outside hosts.
• Microsoft Windows 2003
• Microsoft Windows Vista, Microsoft Windows 2008 and above
Windows 2003
Microsoft Windows 2003 Microsoft Windows 2003 uses a default port range of 1025 through
5000 as the dynamic client port range for outgoing connections. To avoid port conflicts, HP SIM
installer, as part of the installation process, reserves the following ports, if it detects installation on
Microsoft Windows 2003 Operating System. The dynamic ports shown in Table 20 (page 202)
refer to outgoing connections for both TCP and UDP.
