Free wifi

Sunday, March 19th, 2006 09:55pm

需要离公司进一点，搬了宿舍，宽带还没有安装好，上网就成了问题。但是我查了一下，无线网络的用户可真多阿，随便找了几个没有设置密码的连接就上来了;-)。而且有的用户的ap/router的管理密码都还是缺省的。

有两个无线网卡(一个内置、一个挂在阳台上)的笔记本做NAT服务。

自己房间里的无线局域网用这个AP

这样在工作台上的机器无线信号就很好了，上网顺畅;-)

在阳台上的效果要比室内好多了，比如下面的list清单。

fontconfig.properties

如果你在Linux下的jdk1.5程序中文显示有问题(比如Intellij IDEA)，可以把下面的文件复制到”$JAVA_HOME/jre/lib”目录下，文件名是fontconfig.properties。(注意最后一行中文字体的位置)
