Primary Server and Member Server Communication Ports

This section describes the ports and protocols used to allow communication between the primary server and member servers in a Arcserve Backup domain. You can configure the following ports in the PortsConfig.cfg file:

CA Remote Procedure Call service

This is the ONCRPC portmapper service. Other ONCRPC services such as caserved, cadiscovd, caathd, lqserver, camediad, and idbserver use this service for registration. Clients that communicate using the other ONCRPC services first contact the ONCRPC portmapper service to enumerate the ports, and then contact the other ONCRPC service to communicate.

• Default Port: 111
• Protocol: TCP
• Appears in PortsConfig.cfg as: catirpc

Domain service (Cadiscovd.exe)

This service maintains a database of users, passwords, equivalences, and hosts for the Arcserve Backup domain concept. This service is required for GUI communication.

• Default Port: Dynamic Port
• Protocol: TCP
• Appears in PortsConfig.cfg as: cadiscovd

Service controller (Caservd.exe)

This service is used to manage other services remotely and is required for GUI communication.

• Default Port: Dynamic Port
• Protocol: TCP
• Appears in PortsConfig.cfg as: caservd

Authentication service (Caauthd.exe)

This service validates the caroot user login and equivalence. It is required for GUI and backup server communication.

• Default Port: Dynamic Port
• Protocol: TCP
• Appears in PortsConfig.cfg as: caauthd

LDBServer.exe

This service is used for proxy for database communication and can only be configured using the command line. This service is not required for GUI and backup server communication.

• Default Port: Dynamic Port
• Protocol: TCP
• Appears in PortsConfig.cfg as: cadbd

LQServer.exe

Used for proxy for job queue communication and can only be configured using the command line. This service is not required for GUI and backup server communication

• Default Port: Dynamic Port
• Protocol: TCP
• Appears in PortsConfig.cfg as: caqd

Mediasvr.exe

Used for proxy for tape engine communication and can only be configured using the command line. This service is not required for GUI and backup server communication.

• Default Port: Dynamic Port
• Protocol: TCP
• Appears in PortsConfig.cfg as:

Carunjob.exe

Uses a port range for reconnection logic (on network communication failure) with the agents.

• Default Port: Dynamic Port
• Protocol: TCP
• Appears in PortsConfig.cfg as: reconnection

Arcserve Management Service (casmgmtsvc.exe)

Arcserve Management Service is a configurable service that lets Arcserve Backup command line utilities (for example, ca_backup and ca_restore) communicate under the following scenarios:

• Remote services communication

  Note: To communicate using remote services, Arcserve Management Service requires a callback service.

• Arcserve server and client server communication

  Note: To communicate with the Arcserve server and the client server, Arcserve Management Service requires a callback service.

Location of Configuration Files

• CA Management Configuration File: To modify the ports used by Arcserve Management Service, you must modify the configuration file labeled mgmt.properties located in the following directory:

  <$ARCserve_Home>\MgmtSvc\conf\mgmt.properties
  

• Callback Services Configuration File: Arcserve Management Service requires a callback service labeled clntportrange. clntportrange is a value listed in the mgmt.properties configuration file located in the following directory:

  On 64-bit platform:

  <drive letter>\Program Files (x86)\CA\Shared Components\ARCserve Backup\jcli\conf\mgmt.properties
  

  On 32-bit platform:

  <drive letter>\Program Files\CA\Shared Components\ARCserve Backup\jcli\conf\mgmt.properties
