리눅스에서 arp cache 삭제/초기화 하는 방법

2015-05-28 KENNETH 0

arp 상태 확인 arp -a 개인적으로 arp -n 을 하면 좀더 보기좋게 정렬되서 -n 을 사용하는게 좋다고 생각한다… 개인적으로 실행하면 아마도 정상적으로 네트워크에 참여한 상황을 기준으로 뭔가 목록(아이피 + mac주소)이 나온다.   초기화 방법 1. 터미널에서 아래 명령을 실행 2. ip -s -s neigh flush all 실행후 다시 ”arp -a ” 또는 ”arp -n” 명령으로 확인해보면 목록이 싹 사라진것을 확인할 수 있다. 윈도우에서의 결과와는 살짝 다름

PHP 지원기간 안내 (PHP Supported Versions)

2015-04-03 KENNETH 0

Supported Versions Each release branch of PHP is fully supported for two years from its initial stable release. During this period, bugs and security issues that have been reported are fixed and are released in regular point releases. After this two year period of active support, each branch is then supported for an additional year for critical security issues only. Releases during this period are made on an as-needed basis: there may be multiple point releases, or none, depending on the number of reports. Once the three years of support are completed, the branch reaches its end of life and is no longer supported. A table of end of life branches is available. Currently Supported Versions Branch Initial Release Active Support Until Security Support Until 5.4 1 Mar 2012 3 years, 1 month ago 14 Sep 2014 6 months ago [ more… ]
