Link-local address(169.254.0.0/16)

2011/08/08 09:55 3-5. Networks
가끔 랜카드가 IP를 169.254.23.3 이렇게 잡는 경우가 생긴다. 
어이 없는 네트워크 대역이라 생각 되지만.. IP프로토콜에 정의된 대역이였다.. 

http://en.wikipedia.org/wiki/Link-local_address

번역해서 요약해보자면.. 내부내트워크의 연결 혹은 P-to-P 간의 연결을 위해 만들어진 IP대역이고 라우터에서 처리해주지 않는다. DHCP나 다른 ip 설정메소드에 실해 했을 설정이 된다는것 같네요.. 발번역 죄송.

/proc/loadavg

2011/08/02 17:42 3-1. Linux

3.2.16. /proc/loadavg

This file provides a look at the load average in regard to both the CPU and IO over time, as well as additional data used by uptime and other commands. A sample /proc/loadavg file looks similar to the following:

0.20 0.18 0.12 1/80 11206

The first three columns measure CPU and IO utilization of the last one, five, and 15 minute periods. The fourth column shows the number of currently running processes and the total number of processes. The last column displays the last process ID used.

In addition, load average also refers to the number of processes ready to run (i.e. in the run queue, waiting for a CPU share.
