NetworkManager无法连接网络的解决方法

原创内容,转载请注明出处: https://www.myzhenai.com.cn/post/1907.html https://www.myzhenai.com/thread-16342-1-1.html 昨天手痒，把CenTos6.5升级到CenTos6.6了，但升级结束后却发现我无法拨号上网了，NetworkManager连接程序一直显示一个红叉.把我吓一跳，因为我的系统里安装了很多的程序，如果要重装系统的话还得重新安装这些程序，非常麻烦. 一下子着急上火了. 然后到 /var/log/messages日志里总是不停的提示以下的错误.搜索整个网络也没有相应的解决方法，我还特意给GNOME和NetworkManager官方发了求助邮件，但可惜没有收到他们的回复.没办法，只好自己折腾.我以为是因为NetworkManager升级的源故，因为这次系统升级的包里刚好有几个NetworkManager的更新包.于是我把NetworkManager的所有程序全部remove了，然后重新安装这个版本的NetworkManager，但也没有得到解决，仍然是无法连接网络，再继续排查messages日志也没有得到思路.

CenTos下配置OpenVPN时无法导入用户私钥的解决方法

前些天遇到一个问题，不知道为什么我配置的Pptpd和OpenVPN都无法连接了，不知道是不是BuyVM升级了OpenVZ补丁所至，反正是两种VPN方法都无法连接了，我重装了几遍始终解决不了，因些还与BuyVM的技术客服-jessie沟通了好几天，我把服务器上的CenTos5.8升级到了CenTos6.4，并且-jessie帮我重新布署了Pptp和OpenVPN,但是最后我配置本地的时候却还是发现无法连接，于是我又将服务器重装了，重装安装和配置了Pptpd和OpenVPN，最后我发现Pptpd无法连接是我本地客户端的问题，可能系统缓存了什么错误的密码或是其他东西，我重新配置后可以了，详情可以参考Centos下PPtpD本地无法连接的解决方法，最烦人的是OpenVPN的配置，在本地CenTos＋NetworkManager-openvpn里却看不到用户私钥文件，但是这个文件我已经从服务器上下载到本地了，始终无法导入用户密钥文件，我以为是服务器上生成的key文件有问题，还在本地进行了生成，但还是无法解决，这个问题我问了好多社区，并且在一些Linux技术群里询问都得不到解决方法.搜索网络上也找不到相应的问题，所以只好自己折腾，经过两天的折腾，终于解决了，故障发生原因我不知道，可能是easy-rsa文件包里的openssl生成密钥文件的时候加密过程中发生了什么，所以无法正常导入.

Centos6+GNOME+NetworkManager配置VPN客户端

转载请注明出处：https://www.myzhenai.com/thread-15104-1-1.html https://www.myzhenai.com.cn/post/767.html 我的系统配置是Centos6+GNOME+NetworkManager，为了一个VPN终端，我是折腾了好久了，命令行下的折腾好了，却发现NetworkManager却始终无法正常使用.可以新建VPN链接，但无法使用，无法新建pptp通道协议VPN.原来是NetworkManager-vpnc,NetworkManager-pptp,NetworkManager-openvpn这三个插件无法安装，Centos的依赖太严格了,提示少了libnm-util.so.2,libgdk-3.so.0,libnm-glib.so.4,libnm_glib_vpn.so.0,libnm_glib.so.0,libnm-util.so.2,libgdk-3.so.0,libgtk-3.so.0等依赖包.折腾了好久才折腾好，不过是换了个方式解决的.
