给大家带来CentOS下搭建一台VPN办事器完成内部收集毗连外部收集
我也是坐沙发的 这种补充有助于他人在邮件列表/新闻组/论坛中搜索对你有过帮助的完整解决方案，这可能对他们也很有用。 我学习Linux的心得体会 ，希望对大家的学习有所帮助，由于水平有限，本文难免有所欠缺，望请指正。 Linux的成功就在于用最少的资源最短的时间实现了所有功能，这也是符合人类进化的，相信以后节能问题会日益突出。 说实话小时候没想过搞IT，也计算机了解也只是一些皮毛，至于什么UNIX，Linux，听过没见过，就更别说用过了。? 写学习日记，这是学习历程的见证，同时我坚持认为是增强学习信念的法宝。 其次，Linux简单易学，因为我们初学者只是学的基础部分，Linux的结构体系非常清晰，再加上老师循序渐进的教学以及耐心的讲解，使我们理解起来很快，短期内就基本掌握了操作和运行模式。
