xtreamer 开机自动加载transmission

March 5, 2012

transmission 需要用 sda1 做download的目录 所以不能简单的在init.d里面直接启动 应为如果如果sda1没有加载成功,transmission 也启动不了 下面这个启动脚本 先检查 sda1,mount以后,在启动transmission,这样就不会有问题了:)   #!/bin/sh cnt=30 dev=sda1 mountpoint=/tmp/usbmounts/$dev while [ "$cnt" -gt "0" ]; do let cnt=cnt-1 if [ -d $mountpoint ]; then     /sbin/www/xmproot/.transmissionconfig/transmission_start.sh     echo "Transmission_daemon started (`date`) "  >> /sbin/www/xmproot/xmp/startup.log #    echo ok   break fi sleep 2 done exit 0

用inssider 优化wifi连接

March 3, 2012

inssider是个小工具,用来检测周围wifi的频段情况 可以看到2.4g 被各种热点填满了 能做的就是选一个信号叠加小的频道 5g 几乎没有人用,是一劳永逸的解决方法:)
