Cisco WSA : What is RADIUS CLASS attribute ?

Hello !
I am trying to use a radius server Cisco ISE as an external authentication server for WSA. I would like to assign roles for groups of users but i don't understand the meaning of RADIUS CLASS attribute. What am I supposed to write in this field ?
Thank you,
Stéphane Walker

The CLASS attribute is generic, in that you can put anything in it. So you get to decide what you use.
On your RADIUS box, for the users or group that it applies to, set it to something like "WSAAdmin" for admins, "WSARO" for read only users...
Then when you config the WSA, you set them appropriately there...
But you can really use any string you want to, they just need to match appropriately.

Configuring Cisco ISE for Authorization with External Radius Server attribute

Hi,
I'm trying to integrate an external radius server with Cisco ISE.
I created an External Identity Store>Radius Token Server.
I created a Identity Store sequence with just one identity store just as creadted above.
And I was able to authenticate successfully.
But when it comes to authorization.
I observed we just have one tab named Authorization while creating Radius Token server.
And it always refers to ACS:attribute_name.
If I want to define a IETF radius attribute, (lets say class with attribute id as 25), how could I do it.
In Cisco ACS we have a direct entry option in authorization tab where we can define the radius (IETF) attribute within Radius token server creation (within radius token server>Directory attribute tab).
How ever I try to define the IETF attribute here (class,IETF:Class) I am not able to authorize with this attribute value.
I tried with just one single authorization rule where it could hit.But observed it to go the default(as none of the rules defined matches the condition).
Can anyone guide me how can we define a IETF radius attribute for authorization within Cisco ISE and what policy could we set it to work as authorization.
Thanks in advance

This is the step of Creating and Editing RADIUS Vendors
To create and edit a RADIUS vendor, complete the following steps:
Step 1 From the Administration mega menu, choose Resources > RADIUS Vendors.
The RADIUS Vendors page appears with a list of RADIUS vendors that ISE supports.
Step 2 Click Create to create a new RADIUS vendor or click the radio button next to the RADIUS vendor that
you want to edit and click Edit.
Step 3 Enter the following information:
• Name—(Required) Name of the RADIUS vendor.
• Description—An optional description for the vendor.
• Vendor ID—(Required) The Internet Assigned Numbers Authority (IANA)-approved ID for the
vendor.
• Vendor Attribute Type Field Length—(Required) The number of bytes taken from the attribute value
to be used to specify the attribute type. Valid values are 1, 2, and 4. The default value is 1.
• Vendor Attribute Size Field Length—(Required) The number of bytes taken from the attribute value
to be used to specify the attribute length. Valid values are 0 and 1. The default value is 1.
Step 4 Click Submit to save the RADIUS vendor.

Cisco Nexus to use Radius AAA authentication using Microsoft 2008 NPS

I have a Nexus 7010 running
Just wondering if you can help me with something. I'm having an issue with command authorization thru our aaa config. We don't have a problem authenticating its command authorization that is not working. From what I have seen and read Nexus NX-OS 6.x does not have any commands for aaa authorization unless you are configuring TACACS+. My basic config is below if you can help it would be much appreciated.
>>ip radius source-interface mgmt 0
>>radius-server key XXXXX
>>radius-server host X.X.X.X key XXXXX authentication accounting
>>radius-server host X.X.X.X key XXXXX authentication accounting aaa
>>authentication login default group Radius_Group aaa authentication
>>login console local aaa group server radius Radius_Group
>>    server X.X.X.X
>>    server X.X.X.X
>>    source-interface mgmt0
Also does anyone know how to configure Microsoft 2008 NPS as a Raduis server to work with Nexus? I have read a few post that suggest changing the
shell:roles="vdc-admin" in the Attribute Value field in the RADIUS server
Does anyone know if this works????
Thanks

I have never done this before with ACS but not with NPS. However, you are in the right path. Nexus uses NX-OS which is different in some regards to regular IOS. One of those differences is the AAA setup. In NX-OS you assign users to roles. So for full access you will need to return the following attributes from your Radius server:
Attribute: cisco-av-pair
Requirement: Mandatory
Value: shell:roles*"network-admin vdc-admin"
For more information take a look at this link:
http://www.cisco.com/c/en/us/support/docs/security/secure-access-control-system/115925-nexus-integration-acs-00.html
Hope this helps

Parsing vsa:not a cisco vendor id:311 – radius

Hi,
We are getting "parsing vsa:not a cisco vendor id:311 – radius" error logs from Nexus. What is the impact of this log?

Hello Folks,
The error msg occurs when a Cisco device receives a Radius VSA that is not cisco. VSA 311 belongs to Microsoft so it might be that you are indeed not using a Cisco radius VSA. The error is not harmful.
https://technet.microsoft.com/en-us/library/cc958030.aspx
RADIUS: Attribute length = 12 (0xC)
RADIUS: Vendor ID = 311 (0x137)<<<<<<<<<<<<<<<<<<<
RADIUS: Vendor string = _
The way to stop seeing the error messages depend on the Cisco device in which you are seeing it, in nexus it is "Logging level user 2".
I hope it helps.

Page Attributes and Application Class Attributes

Hi, everyone,
I am quite new to BSP.
I have a question here:
what is the difference between page attributes and application class attributes of a bsp application? As they are both global attributes, there seems to be no big difference when we use them.
thanks a lot.
Fan

Hi Fan,
a BSP application can be made up of many pages.
A page attribute is visible only in the page it is associated with.
Attributes of the application class are visible from every page in that application.

Jar files and Main-Class attribute

Sorry, I know there are other topics regarding this argument but none of them helped me solving my problem.
I've tried a thousand time in every possible way, but I still can't run my application from a jar file. I've got a package called client, whose main class is called Client. The package contains a sub-package called Icons. I've put everything into a jar file and added this manifest:
Manifest version: 1.0
Name: client/
Sealed: True
Main-Class: client.Client
But it won't work. I've tried to erase the Sealed part, I've tried "Main-Class: Client" and also "client/Client", I've tried putting into the jar the client directory and I've tried omitting it, but the answer is always the same:
Failed to load main-class header etc.
Can anyone help me? Please, I'm almost desperate!
Thanks

the same procedure with the addition of "Name: client/" before the main-class attribute generated the usual "Failed to load Main-Class manifest attribute" result. So now what?!? I'm getting crazy....

Class attribute in technical workflow log not updated

Hi Gurus,
I built a workflow analogous to the famous demo workflow "demoformabs" but with the demo class: CL_SWF_FORMABSENC instead of the BOR: FORMABSENC.
In the BOR Formabsenc there is also an attribute for the "Approver" (USR01) in addition to "Creator" (USR01).
This attribute "Approver" is missing in the class "CL_SWF_FORMABSENC".
So I added this attribute "Approver" also in the class "CL_SWF_FORMABSENC":
data APPROVER type SIBFLPORB value CL_SWF_BOR_TYPES=>MC_USR01.
Finally in the method "approve" I set the value for the attribute "APPROVER".
me->approver-instid = me->APPROVBY.
I can see that the value has been successfully set by setting a binding from this class attribute to a workflow container element.
BUT, in the technical workflow log (container) I can not see the class attribute "Approver" populated.
Here it´s still displayed as < no instance >.
What do I need to do, to make this value appear also in this class attribute in the technical workflow log?
Albeit I know, that it´s working, I am getting confused, that it´s still displayed as empty.
Cheers,
Dominik

Hi Dominik,
You should not populate attributes in this manner, for the very reason you're experiencing. Attributes are transient and behave like variables, i.e. when the class stops existing they disappear. During binding only the key is transferred, and - if needed - the class is re-instantiated at the other end. If you have implemented some kind of buffering/instance management (not a bad idea), then you may be lucky to have attributes survive if everything happens within the same program context. However once your WF session stops executing, this is lost.
This is why when you look at the log later, it is re-instantiating a completely new instance - where would it know the approver from?
The attribute value must be written to the DB somewhere, so that any later object instantiation (e.g. when you look at the log) will read the value and populate the attributes correctly.
Incidentally this is why OO theory discourages the use of public attributes and suggests GET_ and SET_ methods instead....
Regards,
Mike

Robohelp 8 & CSS Class attribute

I have been trying to use the CSS Class attributes but it doesn't seemed to be recognized by Robohelp 8. Here is an example of my code:
My external style sheet:
Test {
          width: 562px;
          height: 16px;
          text-align: center;
          font-family: Arial, Helvetica, sans-serif;
          font-weight: bold;
          color: #ffff00;
Test1 {
          background-color: #00900;
Test2 {
          background-color: #008000;
In my file:
<link rel="Stylesheet" href="layout.css" type="text/css" />
<div class="Test Test1">
     I type something here
</div>
The text that I type is rendered but none of the formatting. What am I doing wrong?
Does anyone know if there is a problem with Robohelp 8 not supporting CSS classes?
Thanks!
Message was edited by: Lakooli

Hi,
Add a dot (.) before the class definitions in your css:
.Test -> All elements that have the class test
Or even better:
div.Test -> Only DIV element that have the class test

Pack and unpack Radius VSA attributes

Hi
As far as I know there are some methods to pack radius VSA attributes. Here are:
As the part of Cisco-AVPair
26 - VSA
Length
9 - Vendor ID
1 - Vendor Type (Cisco-AVPair Attribute ID)
Attribute Name=Value
In the Vendor Specific attribute ("throught attribute ID")
26 - VSALength
9 - Vendor ID
2 - Vendor Type (Attribute ID)
Vendor Length
Attribute Name=Value
In the Vendor Specific attribute ("throught attribute ID")
26 - VSA
Length
9 - Vendor ID
2 - Vendor Type (Attribute ID)
Value
i.e. with attribute name and witout.
How to understand which attribute needs attribute name in value string?
For example:
26|Length|9|2|Vendor Length|1|h323-incoming-conf-id=82b5fc8cd6f411dfa3c6080027716a9a
26|Length|9|2|Vendor Length|35|h323-incoming-conf-id=82b5fc8cd6f411dfa3c6080027716a9a
26|Length|9|2|Vendor Length|35|82b5fc8cd6f411dfa3c6080027716a9a
which of the methods is right?

Hi,
For the specific VSA you used in the example (h323-incoming-conf-id), (1) is the correct encoding, since Cisco VSA vendor type 1 (also more commonly referred to as cisco AV Pair) is always encoded in strings with the format of "attribute=value". This applies to other cisco VSAs that use string encoding as well. For VSA's that don't use string encoding, eg., fax-pages (vendor type 5, encoding integer), it typically doesn't include the value. You should be able to check that against the vendor dictionary to confirm. Please also see:

Could anyone tell me what is a class

Hi gurus,
could anyone explain me in detail what does a class mean (se24) in sap and for what it is used? i have tried my best to know about it. it is like greek and latin to me.
Thanks in advance,
Ramana

Classes describe objects. From a technical point of view, objects are runtime instances of a class. In theory, you can create any number of objects based on a single class. Each instance (object) of a class has a unique identity and its own set of values for its attributes.
classes consist of ABAP source code, enclosed in the ABAP statements CLASS ... ENDCLASS. A complete class definition consists of a declaration part and, if required, an implementation part. The declaration part of a class <class> is a statement block:
CLASS <class> DEFINITION.
ENDCLASS.
It contains the declaration for all components (attributes, methods, events) of the class. When you define local classes, the declaration part belongs to the global program data. You should therefore place it at the beginning of the program.
If you declare methods in the declaration part of a class, you must also write an implementation part for it. This consists of a further statement block:
CLASS <class> IMPLEMENTATION.
ENDCLASS.
The implementation part of a class contains the implementation of all methods of the class. The implementation part of a local class is a processing block. Subsequent coding that is not itself part of a processing block is therefore not accessible.
Structure of a Class
The following statements define the structure of a class:
A class contains components
Each component is assigned to a visibility section
Classes implement methods
The following sections describe the structure of classes in more detail.
Class Components
The components of a class make up its contents. All components are declared in the declaration part of the class. The components define the attributes of the objects in a class. When you define the class, each component is assigned to one of the three visibility sections, which define the external interface of the class. All of the components of a class are visible within the class. All components are in the same namespace. This means that all components of the class must have names that are unique within the class.
There are two kinds of components in a class - those that exist separately for each object in the class, and those that exist only once for the whole class, regardless of the number of instances. Instance-specific components are known as instance components. Components that are not instance-specific are called static components.
In ABAP Objects, classes can define the following components. Since all components that you can declare in classes can also be declared in interfaces, the following descriptions apply equally to interfaces.
Attributes
Attributes are internal data fields within a class that can have any ABAP data type. The state of an object is determined by the contents of its attributes. One kind of attribute is the reference variable. Reference variables allow you to create and address objects. Reference variables can be defined in classes, allowing you to access objects from within a class.
Instance Attributes
The contents of instance attributes define the instance-specific state of an object. You declare them using the DATA statement.
Static Attributes
The contents of static attributes define the state of the class that is valid for all instances of the class. Static attributes exist once for each class. You declare them using the CLASS-DATA statement. They are accessible for the entire runtime of the class.
All of the objects in a class can access its static attributes. If you change a static attribute in an object, the change is visible in all other objects in the class.
Methods
Methods are internal procedures in a class that define the behavior of an object. They can access all of the attributes of a class. This allows them to change the data content of an object. They also have a parameter interface, with which users can supply them with values when calling them, and receive values back from them The private attributes of a class can only be changed by methods in the same class.
The definition and parameter interface of a method is similar to that of function modules. You define a method <met> in the definition part of a class and implement it in the implementation part using the following processing block:
METHOD <meth>.
ENDMETHOD.
You can declare local data types and objects in methods in the same way as in other ABAP procedures (subroutines and function modules). You call methods using the CALL METHOD statement.
Instance Methods
You declare instance methods using the METHODS statement. They can access all of the attributes of a class, and can trigger all of the events of the class.
Static Methods
You declare static methods using the CLASS-METHODS statement. They can only access static attributes and trigger static events.
Special Methods
As well as normal methods, which you call using CALL METHOD, there are two special methods called CONSTRUCTOR and CLASS_CONSTRUCTOR, which are automatically called when you create an object (CONSTRUCTOR) or when you first access the components of a class (CLASS_CONSTRUCTOR).
Events
Objects or classes can use events to trigger event handler methods in other objects or classes. In a normal method call, one method can be called by any number of users. When an event is triggered, any number of event handler methods can be called. The link between the trigger and the handler is not established until runtime. In a normal method call, the calling program determines the methods that it wants to call. These methods must exist. With events, the handler determines the events to which it wants to react. There does not have to be a handler method registered for every event.
The events of a class can be triggered in the methods of the same class using the RAISE EVENT statement. You can declare a method of the same or a different class as an event handler method for the event <evt> of class <class> using the addition FOR EVENT <evt> OF <class>.
Events have a similar parameter interface to methods, but only have output parameters. These parameters are passed by the trigger (RAISE EVENT statement) to the event handler method, which receives them as input parameters.
The link between trigger and handler is established dynamically in a program using the SET HANDLER statement. The trigger and handlers can be objects or classes, depending on whether you have instance or static events and event handler methods. When an event is triggered, the corresponding event handler methods are executed in all registered handling classes.
Instance Events
You declare instance events using the EVENTS statement. An instance event can only be triggered in an instance method.
Static Events
You declare static events using the CLASS-EVENTS statement. All methods (instance and static methods) can trigger static events. Static events are the only type of event that can be triggered in a static method.
See also Triggering and Handling Events.
Types
You can define your own ABAP data types within a class using the TYPES statement. Types are not instance-specific, and exist once only for all of the objects in a class.
Constants
Constants are special static attributes. You set their values when you declare them, and they can then no longer be changed. You declare them using the CONSTANTS statement. Constants are not instance-specific, and exist once only for all of the objects in a class.
Visibility Sections
You can divide the declaration part of a class into up to three visibility areas:
CLASS <class> DEFINITION.
PUBLIC SECTION.
PROTECTED SECTION.
PRIVATE SECTION.
ENDCLASS.
These areas define the external visibility of the class components, that is, the interface between the class and its users. Each component of a class must be assigned to one of the visibility sections.
Public Section
All of the components declared in the public section are accessible to all users of the class, and to the methods of the class and any classes that inherit from it. The public components of the class form the interface between the class and its users.
Protected Section
All of the components declared in the protected section are accessible to all methods of the class and of classes that inherit from it. Protected components form a special interface between a class and its subclasses. Since inheritance is not active in Release 4.5B, the protected section currently has the same effect as the private section.
Private Section
Components that you declare in the private section are only visible in the methods of the same class. The private components are not part of the external interface of the class.

JavaBeans class attribute problem

Hi,
I am using JavaBeans in my JSP application to represent the business logic. I am just writing a simple JavaBean to calculate wages. The bean(which is called PayBean) compiles fine and the class resides in the folder \web-inf\classes\com\mybean\pay\
In the JSP page I have
<jsp:useBean id="payBean" class="com.mybean.pay.PayBean"/>to call my bean.
However, when I ran the JSP I get the following error:
The value for the useBean class attribute com.mybean.pay.PayBean is invalid.
I tried restarting tomcat, but to no avail. Does anyone know what is wrong with my code?
I have written and used bean using the same procedure and it ran fine, so I am really puzzled.
Thanks

Your bean payBean must have a public constructor that takes no arguments. (or no constructor at all, in which case it automatically gets one)
ie
package com.mybean.pay.PayBean
public class PayBean{
public PayBean(){
}Cheers,

How to check if Cisco WSA is already blocking the malicious sites?

How to check if Cisco WSA is already blocking the malicious sites?

Depends on what you mean, but in general what you did will not work.
The usual intent of RMI is to have several processs running and all of them use one process as the repository.
A static value is only visible in one VM instance thus it will not be visible in another process.
So in that situation you could check if the the server socket that the RMI using is open. But just catching the exception, presuming that you catch the correct one, is also sufficient.

What is data Class ?

Hi.
I need to know what is "data class". I am aplying a hot package in SAP, and it generated a error because el data class USR34 not exists associated with cdhdr table. The note says that I must create it, but I don´t know how I must to do it.
And I don't know if I can associate other data class that exists as USR33.
Thanks for your help.

Hello Maria,
Data class is a technical attribute of a table.
Data class in technical settings
    The data class defines the physical area of the database (for ORACLE the
    TABLESPACE) in which your table is logically stored. If you choose a
    data class correctly, your table will automatically be assigned to the
    correct area when it is created on the database.
    The most important data classes are (other than the system data):
    o   APPL0    Master data
    o   APPL1    Transaction data
    o   APPL2    Organizational and customizing data
    Master data is data which is frequently read, but rarely updated.
    Transaction data is data which is frequently updated. Organizational und
    customizing data is data which is defined when the system is initialized
    and then rarely changed.

Vasanth
