Java处理Radius access-challenge

最近使用 RSA Authentication Manager， 并且与其自带的Radius server整合， RSA的Radius server 配置不太透明， 目前只配成功了PAP方式的验证，CHAP目前不成功。

RSA Radius在token输错3次后有要求用户输入next token的安全设置方式， 开始不知道java如何处理，后来查了一些资料，Radius协议本身是无状态的，客户端第二次next token

的request需要跟上前一次response中的state才能让服务器识别出这个session，跟http 的 session是一个意思。

// next token new request send
                    AttributeList response = r.getAttributes();
                    AttributeList state = response.getAttributeList(Attribute.State);
                    System.out.println(">>>>>>>Response state:" + state);
                    System.out.println("next Token");
                    Scanner sa = new Scanner(System.in);
                    String sl = sa.next();
                    String mima = sl + "";
                    System.out.println(mima);
                    AttributeList attList = new AttributeList();
                    attList.addAttribute(Attribute.NAS_Port, 1);
                    attList.mergeAttributes(state);
                    int nResul = r.authenticate("ryan", mima, attList);

注意这个

r.authenticate("ryan", mima, attList);

处理的是PAP格式的请求。
