[问题]校园网上网提示多网卡问题

[bangquanzhang]

我安装了学校的登录端（深澜客户端），但它只允许一台计算机一块网卡（物理网卡，虚拟网卡都算），我的机子只有一块物理网卡，但它就是一直提示“多个NIC”，我就只安装了默认的Ubuntu8.04系统，没有额外安装其他程序，我的问题是在安装默认的Ubuntu系统时，它会虚拟出一些网卡来吗？
我可以怎样做来获取系统中到底有没有虚拟网卡？我用过ifconfig，也禁用过IPv6和lo（环回)，都还是提示多个NIC（网卡）。
另外一个问题，我觉得可能是与系统“网络设置”中的那个“点对点连接“有关，怎样才可以去掉它，卸载掉？
3个问题，有点多！麻烦各位耐心帮忙看一下，小弟不胜感激！

在ifconfig里面有几个interface？

我试着用过sudo ifdown lo关闭lo后登录，同样提示多NIC，禁用ipv6后也同样是多NIC，在3楼你可以看见现在我已经禁用了ipv6。现在我觉得可能与“网络设置”中的“点对点连接”有关。我一直想禁用它，苦于一直没找到办法。[/img]

[philsc]

弱弱的路过。。。我也遇过这个问题。。。貌似跟ipv6与PPPoe没关系。。。

你遇到过这个问题，最后解决了没有？如果解决了，办法是怎样的！如果与ipv6和ppppoe没关系，与什么可能有关系，你的建议是什么？

同问，刚装上Ubuntu8.04，遇到和楼主一样的问题，深澜客户端登录时一直在显示“正在登陆”，就没反应了。。。需要做什么网络设置？
