Port Configuration - Modification Examples

The following are some examples of how to modify the PortsConfig.cfg file.

Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Open Network Computing Remote Procedure Call (ONCRPC) services require only one port. If you do not provide a port number for these services, the default, hard-coded port is used. If you specify a port range, only the first available port from the range is used. The following are examples of how to change a TCP service:
```
sqlagenttcpservice			8000		machine_name
```
or
```
fsbackupservice			7000		machine_name
```
or
```
exchangeagenttcpserverlevel		6000		machine_name
```
Machine A and D are Arcserve Backup servers. Machine B and C are Client Agent machines. If you want to change the communication port between machine A and B to 7000 and set the communication port between A and C the default - 6050. Also on the machine A there is a client agent installed for the Arcserve Backup server on machine D and you want to change the communication port from D to A to 8000.
On machine B - client agent, add following lines to the PortsConfig.cfg file:
```
fsbackupservice			7000		MachineB
```
```
fsbackupserviceudp			7000		MachineB
```
- You can perform this change using the Admin.exe application installed by the client agent.
- You must restart the Universal Agent service.
Machine A and D are Arcserve Backup servers. Machine B and C are client agent machines. If you want machine A to browse and backup files on machine B, add the following to PortsConfig.cfg file.
```
fsbackupservice			7000		MachineB   
```
```
fsbackupserviceudp			7000		MachineB 
```
To allow the client agent from machine A to communicate with the Arcserve Backup machine D, add the following lines to the PortsConfig.cfg file on machine A:
```
fsbackupservice			8000		MachineA   
```
```
fsbackupserviceudp			8000		MachineA
```
You must restart the Universal Agent on machine A.

Note: You can apply this theory to the Arcserve Backup Agent for Microsoft SQL Server (sqlagenttcpservice) and the Arcserve Backup Agent for Microsoft Exchange Premium Add-on (exchangeagenttcpserverlevel) for TCP services (fsbackupservice, sqlagenttcpservice, exchangeagenttcpserverlevel).
For Arcserve Backup MSRPC services:
MSRPC listens over “ncacn_ip_tcp” and “ncacn_np” protocols. The “ncacn_ip_tcp” uses system assigned ports by default, rather than hard-coded ports. The hostname and IP address are not required for the RPC Services.

For example, a change for an MSRPC service could be:
```
dbagentsrpcserver			9000
```
Arcserve Backup Agent RPC Server will try to use port 9000.
```
dbagentsrpcserver			9000;9001
```
Arcserve Backup Agent RPC Server will try to communicate using port 9000; if it does not succeed it will try to use port 9001. If it does not succeed Arcserve Backup will write a message in the Windows Application Activity Log.
```
dbagentsrpcserver			9000-9500
```
Arcserve Backup Agent RPC Server tries to communicate using port 9000. If it does not succeed Arcserve Backup will try to communicate using port 9001, and continue to attempt to communicate up to port 9500.

If it cannot use any port in the range, will write a message in the Windows Application Activity Log.
