锐捷认证常见问题解答 2008-04-24 19:05 锐捷网络在中国网络设备市场的占有额不容小视(特别在教育行业),国内各大高校认证系统使用锐捷的RGSAM认证系统的也是非常的多;身为一个网管人员,是有必要把锐捷认证时出现的一些问题及解决方式与同行们交流。现“总结”下这一年多来的认证问题及解决方式,希望在公网上有人能补缺补漏;让校园网运行的更加畅通~ 锐捷认证客户端常见问题解答(WINDOWS下的FAQ): 故障现象1:客户端提示“找不到合适的网卡” 故障现象2:客户端提示“目前系统工作环境与软件运行环境相冲突,软件不能正常运行CODE,2” 故障现象3:客户端提示“目前系统工作环境与软件运行环境相冲突,软件不能正常运行CODE,4” 故障现象4:认证失败,没有任何错误提示 故障现象5:认证失败,提示“已达到最大连接数” 故障现象6:无法认证,提示“网卡未连接上” 故障现象7:无法认证,认证客户端停顿在:寻找认证服务器。。。 故障现象8:无法认证,认证客户端停顿在:连接认证服务器。。。 故障现象9:“当前系统与工作环境冲突,code=6″ 文中所有关于认证客户端软件的使用及操作适用于所有windows XP 操作系统。 故障现象1:客户端提示“找不到合适的网卡” 原因:系统没有正确获得网卡信息,或者网卡有问题 解决办法:退出并重新打开客户端,如果问题依旧存在,请将网卡驱动程序卸载重装,如果还是不能解决问题,更换一张网卡。 故障现象2:客户端提示“目前系统工作环境与软件运行环境相冲突,软件不能正常运行CODE,2” 原因:安装了多块网卡,和服务器要求的不符合 解决办法:卸载或者禁用多余网卡,只保留一张网卡运行(如果是win98系统,禁用拨号适配器)。 另:有时安装完摄像头也会有此提示信息,只要在安装完摄像头摄动程序后不拔出摄像头重启电脑系统就可以了;还有安装虚拟机时,也会提示code=2, 那是因为虚拟机也会虚拟出一块网卡,这与系统的多网卡本质是一样的。因此,我们不建议使用安装虚拟机的电脑上网~ 禁用多余网卡驱动程序的方法:我的电脑–属性–硬件–设备管理器–查看–显示隐藏的设备–网络适配器–停用。 故障现象3:客户端提示“目前系统工作环境与软件运行环境相冲突,软件不能正常运行CODE,4” 原因:安装了代理服务器,和服务器要求的不符合 解决办法:关闭或卸载代理服务器以及一切可能成为代理服务器的软件(比如自己建立的SMTP邮件服务器,FTP文件下载服务器等);但有时如果系统中病毒的话,也会有此提示信息。 故障现象4:认证失败,没有任何错误提示 intensive development.

Multiple groups: the relatively compact area layout, each district consists of multiple groups, and the area has both integrated urban functions, and have their own characteristics and perimeter formation Li Zhuang, Li Zhuangdong characteristic tour area and Hong Kong in group, consists of 17 groups. Band: modern features gathering along the Yangtze River belt. Dvn group in the upper reaches of the jinsha River along the river continues to the East to South stream groups, layout along the city's main commercial, business, administrative, cultural and creative research and development in science and education function of modern service and port equipment manufacturing, liquor, and other features and modern industry. 2.5-2 spatial planning figure 2.6 in Yibin city, Central City urban development vision vision 原因:WINXP用户启用了系统自带的802.1X认证 解决办法:双击网络连接图标,把属性里面的身份验证标签下“启用802.1X身份认证”前的勾去掉。具体参照本文第三节日常使用注意事项中的WINDOS XP用户设置。卸载任何第三方网卡加速软件 如nvidia net mangermant。 故障现象5:认证失败,提示“已达到最大连接数” 原因:同一个账号只能同时认证在线一人。 有两种情况会导致上述情况发生: 1(帐号被盗用。此时请时带上学生证到网络中心咨询,且要在学校的门户网站上更改密码。 2(用户非正常下线后,认证计费系统的在线中还有该用户的信息,例如用户帐号、IP、MAC、交换机IP、交换机端口等。如果此用户再次认证,发现在线用户表中有该用户的信息,认证计费系统将验证用户上传上来的信息和在线用户表进行匹配,如果不完全相同(例如用户更换交换机端口等),认证计费系统将认为此用户是非法用户,提示达到用户数量上线。 解决办法:带上学生证及时到网络中心咨询、寻求帮忙。 故障现象6:无法认证,提示“网卡未连接上” 原因:网线连接不正确,网线质量差,自己安装的小交换机质量差,交换机柜停电 解决办法:检查网线是否正常,自己安装的小交换机是否正常,确认本楼交换机柜是否停电。如周围同学都是这样的情况,请及时向楼管阿姨反映,叫阿姨开启弱电间的电源开关;或是直接向网络中心联系。 故障现象7:无法认证,认证客户端一直停顿在:“寻找认证服务器”最后提示“认证失败” 原因:网线质量差,或者网卡有问题,或者没有选择“使用私有组播地址认证”;或是楼层里的接入层交换机配置错误。 解决办法:检查网线是否正常,在认证客户端中设置“使用私有组播地址认证”,重装网卡驱动程序,如果问题依旧存在,更换一张网卡 。此时如数据有发送包而没有接收包(为0)可以试着把网卡速率改为10M全双工模式(方法:网络连接–本地连接–属性–配置–高级–link speed/duplex mode–值–10 full mode) 。如果尝试以上操作仍无法解决问题,请向网络中心报修。 故障现象8:无法认证,认证客户端停顿在:连接认证服务器。。。 原因:提供服务的接入交换机到网络中心的服务器通信不正常,可能是某台交换机或者网络中心停电。 解决办法:将此现象网络中心。 故障现象9:“当前系统与工作环境冲突,DHCP获取失败,code=6″ 前言:code=6是个常见的问题,也是最为复杂的一个问题。主要原因是无法动态获取IP地址认证上网~ 症状一:原先网络都能正常动态获取IP地址认证上网,忽然间就code=6 无法获取IP地址认证上网了 解决方法一:查看:开始–运行–输入cmd–输入ipconfig /renew时 如有提intensive development.

(5) have different emphasis: for development, "with development, the emphasis on" way, from space, multiple groups from a single radiation-belt open development. Spatial structure of 2, the prominent cultural city protection elements on the development of the whole city and culture series supporting role, with natural landscapes and green for the background, according to the combined city, urban Group organization structure, set up a decentralized development patterns, building ...

Spatial structure of 2, the prominent cultural city protection elements on the development of the whole city and culture series supporting role, with natural landscapes and green for the background, according to the combined city, urban Group organization structure, set up a decentralized development patterns, building ...
