Modify the TCP/IP settings of an instance

You can modify the TCP/IP settings of a Directory Server instance or a Proxy Server instance.

To modify the TCP/IP settings of an instance with command-line utilities, you must meet the following conditions:

An instance with the same version of command-line utilities must exist.
Stop the Directory Server and the Administration Server of the instance.

Use the following virtual appliance commands to update the IP addresses and port numbers of a Directory Server instance or a Proxy Server instance. To use these commands, you must log in to the virtual appliance command-line interface. See Virtual appliance commands for Directory Server.

idssethost

Use the idssethost virtual appliance command to update the IP addresses.

To update a specific IP address, xx.xx.xx.xx, run the following command:
```
idssethost -I instance_name -i xx.xx.xx.xx
```
To update all IP addresses that are configured, run the following command:
```
idssethost -I instance_name -i all
```

idssetport

Use the idssetport virtual appliance command to update the port numbers.

Note: You must assign a unique port numbers to the Directory Server ports and must not conflict with existing ports that are in use on the computer. On Linux® systems, port numbers in the range of 1 - 1000 can be used only by root.

To update the server port number, run the following command:
```
idssetport -I instance_name -p port_no
```
To update the server secure port number, run the following command:
```
idssetport -I instance_name -s secure_port
```
To update the Administration Server port, run the following command:
```
idssetport -I instance_name -a adm_port
```
To update the Administration Server secure port, run the following command:
```
idssetport -I instance_name -c adm_secure_port
```
