Compiling and binding scripts

Syntax: rename usb0\sys\dpscript\ <initial-script-name> usb0\sys\dpscript\ <new-script-name>

The <initial-script-name> variable is the name of the script file that you want to rename.

The <new-script-name> variable is the new name that you want to create for the script file.

NOTE

A script that is currently bound to a VIP port cannot be renamed.

Display script in the script directory

You can use the dir command to display all of the scripts in the script directory as shown.

ServerIronADX# dir usb0\sys\dpscript

Compiling and binding scripts

Once a script has been copied to ServerIron ADX you must compile it before it can be run. After the

script is compiled, it is ready to run on the ServerIron ADX but it must be bound to a VIP that you it

to operate on. Unless a script is explicitly bound to a VIP it will not effect traffic on the ServerIron

ADX.

This script compile can be done by itself, within the bind operation, or within the process of

updating an existing script. The following is the recommended sequence for binding and

maintaining a script:

1. “Compiling a script and obtaining output from the performance estimator” – We recommend

that you compile a new script using the script compile command before binding it to a virtual

server port. This allows you to make sure that the script compiles successfully and gives you an

estimate of script performance using the Performance Estimator. Once the script is performing

up to your expectation, you can run bind it to the virtual server port.

2. “Binding a script to a virtual server port” – The script binding operation compiles the script

unconditionally and then enables it for packet processing on a specified server port or service.

If compilation errors occur, they are printed to the console or syslog and the bind operation is

aborted.

3. “Updating an existing script”– Once a script has been running, you can make changes to it and

replace it all instances of it in a running configuration. This process compiles the script

unconditionally and if the compile is successful, unbinds the old version from previously bound

virtual server ports and then binds the new script to the same ports.
