Linux磁盘分区UUID的获取及其UUID的作用
一、Linux磁盘分区UUID的获取方法
1、[san@localhost ~]$ ls -l /dev/disk/by-uuid/
total 0
lrwxrwxrwx 1 root root 10 2010-01-18 02:18 0733f5c1-cb85-4f98-9d4f-122cfcee9806
-> ../../sdc1
lrwxrwxrwx 1 root root 10 2010-01-18 01:13 3754-1BDB

VS:
lrwxrwxrwx 1 root root 10 2010-01-18 02:25 0733f5c1-cb85-4f98-9d4f-122cfcee9806 -> ../../sdb1

2、通过blkid命令
[san@localhost ~]$ blkid /dev/sdb1
/dev/sdb1: LABEL="SAN
" UUID="f535fef8-f392-4c84-8e7a-85915d9

例一：发送Signaling Packet：
Signaling Command是2个Bluetooth实体之间的L2CAP层命令传输。所以得Signaling Command使用CID 0x0001.
多个Command可以在一个C-frame（control frame）中发送。
如果要直接发送Signaling Command.需要建立SOCK_RAW类型的L2CAP连接Socket。这样才有机会自己填充Command Code，Identi ......
网络压力测试，需要处理原始数据，将原始的Byte/s 处理为Mbps，并通过直观曲线图表展示出来。
1.统计网卡流量
sar -n DEV 1 100 > net
得到网卡流量，原始数据如下：
10:32:41 IFACE rxpck/s txpck/s rxbyt/s ......
windows下:
1.下载用于 Windows 的 Instant Client Basic 程序包:http://download.oracle.com/otn/nt/instantclient/111070/instantclient-basic-win32-11.1.0.7.0.zip
2.解压缩
创建一个子目录（例如，d:\oci），然后从压缩文件中复制以下库：
oraociei10.dll
orannzsbb10.dll
oci.dll
到此目录下
打开PHP.ini ......
