Web-based System Manager Administration Guide

Enabling Client-Server Mode

In client-server mode (see Modes of Operation), the Web-based System Manager client requests server services from a managed machine through inetd port 9090. Client-server mode needs to be enabled on the servers that are to be managed as remote machines. Enabling and disabling a machine to act as a Web-based System Manager Server can be done through the wsmserver command (see Command Line Tools) as follows:

/usr/websm/bin/wsmserver -enable

To disable a machine so that it cannot be managed from a Web-based System Manager client, type the following command:

/usr/websm/bin/wsmserver -disable

Assigning Port Values

There are two types of ports used with the Web-based System Manager Server: inetd ports and server socket ports. In some cases, the values of these port numbers must be changed.

inetd Ports

The inetd port can service more than one program on your system. If there is another program on your system that uses the inetd port number 9090, change the port number for the Web-based System Manager Server connection with one of the following actions:

set an alternative port number in the /etc/services file. If this is done, the -port argument would be used with the wsm command (see Command Line Tools).
use the following command:
```
wsmserver -enable -listenport port_number
```
where port_number is the new connection port for the Web-based System Manager Server.

When you specify an inetd port number other than 9090, tell the client machine what the new port number is so the client can connect to the server. To specify to the client machine an inetd port number other than 9090, add the host to the client's realm with the following format:

host:port

where host is the name of the server or host machine, and port is the port number.

Server Socket Ports

Server socket port numbers are chosen dynamically from a specified range by the system at runtime. Set the value range with the following command:

wsmserver -enable -portstart range_start -portend range_end

where range_start is the lowest allowable port number and range_end is the highest allowable port number. The Web-based System Manager Server will create sockets within this specified range. If you want multiple Web-based System Manager servers to run at the same time, be sure to specify a port range that allows each server to have its own port.
