Chapter 5 Customizing Your Configuration

Configuring a Remote Server for AA

Step 3 Use the cd command to change to Scripts.

cd /Radius/Scripts

Step 4 Use the add command to add the new script, specifying the name, description, language, filename and an optional entry point. If you do not specify an entry point, Cisco AR uses the script’s name.

The following example specifies the name ParseUserName, the language Rex (which is RADIUS Extension), the filename LibParseUserName.so, and the entry point ParseUserName.

add ParseUserName ""Rex libParseUserName.so ParseUserName

Step 5 Use the save command to save your changes:

save

Step 6 Use the reload command to reload the server.

reload

Handling Multiple Scripts

Cisco AR can run only one script from a given extension point. However, you can write a script that runs several scripts serially, one after the other. For example, the following tcl script, MasterScript, might look like the following:

## this MasterScript executes both tParseAAA and MyProcedure

#it assumes that tclscript.tcl and myscripts.tcl are in the same

#directory as this file

source tclscript.tcl source myscripts.tcl

proc MasterScript { request response environ } { tParseAAA $request $response $environ MyProcedure $request $response $environ

}

Save tcl scripts in the directory /opt/CSCOar/scripts/radius/tcl.

Configuring a Remote Server for AA

All the sites described so far in this chapter have used the Cisco AR RADIUS server for authentication and authorization. You might want to delegate either one or both of those tasks to another server, such as an LDAP server or another RADIUS server.

You can specify one of the following services when you want to use a particular remote server:

radius—authentication and/or authorization

ldap—authentication and/or authorization

tacacs-udp—authentication only.
