unix 계열의 OS에서 log를 저장할 때 실시간으로 log 가 계속 쌓이는 것을 보려면
tail -f <로그파일명> 을 하면 됩니다.
log file 의 내용을 검색 할때는
more <로그파일명> | grep <필터대상> 을 하면 됩니다.
응용을 한다면 tail -f | grep <필터대상> 을 해서 실시간으로 필요한 log 만 확인 할 수도 있겠죠. :)

경로를 드라이브 문자로 지정합니다.
SUBST [드라이브1: [드라이브2:]경로]
SUBST 드라이브1: /D
드라이브1: 경로에 지정할 가상 드라이브를 지정합니다.
[드라이브2:]경로 가상 드라이브에 지정할 실제 드라이브와 경로를
지정합니다.
/D 가상 드라이브를 지웁니다.
매개 변수를 지정하지 않고 SUBST를 사용하면, 현재의 가상 드라이브를 표시합니다.
subst라는 명령어로 가상 드라이브를 만들 수 있습니다.

예제를 보시면 "c:\data\wlse" 의 폴더를 d: 드라이브로 인식하게 만들어 줄 수 있습니다.
탐색기에서도 d: 로 인식을 합니다.
c:\data\wlse 에 자동 실행되는 파일이 있었는데 d: 드라이브로 인식하면서 자동으로 실행 되는 군요.
삭제할때는 위의 경우에는 SUBST d: /D 를 하면 되겠네요. :)

switch의 port 연결 정보 알기(ios)
switch에 host가 연결 되어 있습니다.
어느 port에 연결 되어 있는 지가 궁금 할 때가 있을 것입니다.(과연 -_-)
찾는 방법
1. switch에 접속한다.
2. ping ip(알고자 하는 host)
3. sh arp(알고자 하는 ip & mac address가 나옵니다.)
4. sh mac-address-table | inc mac(알고자 하는 host의 mac)
sh mac-address-table address hh.hh.hh
여기 까지 하면 어느 interface에 연결 되어 있는지 확인 가능 합니다.
더 쉬운 방법이 있다면 귀띔을 ^^
switch의 port 연결 정보 알기(catos)
1.switch에 접속한다.
2.ping ip
3.sh arp
catos는 3번가지만 하면 어느 port에 연결 되어 있는지 확인 가능 합니다.
역시 더 쉬운 방법이 있다면 귀띔을 부탁드립니다.
내용 추가
catos의 경우
명령으로 상대편의 연결 되어 있는 port를 확인 할 수 있습니다.
