/etc/ssh/sshd_config

#Port 22

Port 2222

cat /etc/ssh/sshd_config | egrep ^\#?Port

service sshd restart 또는 service ssh restart

/etc/ssh/sshd_config

#PermitRootLogin yes

PermitRootLogin on

service sshd restart 또는 service ssh restart

SSH 허용IP 설정(외 모든IP 차단)

========================================================

/etc/hosts.allow 수정
# hosts.allow    This file describes the names of the hosts which are
#        allowed to use the local INET services, as decided
#        by the '/usr/sbin/tcpd' server.
#
sshd: 113.157.124.168, 135.79.246.
또는
sshd: 113.157.124.168
sshd: 135.79.246.

/etc/hosts.deny 수정
# hosts.deny    This file describes the names of the hosts which are
#        *not* allowed to use the local INET services, as decided
#        by the '/usr/sbin/tcpd' server.
#
# The portmap line is redundant, but it is left to remind you that
# the new secure portmap uses hosts.deny and hosts.allow.  In particular
# you should know that NFS uses portmap!
sshd: ALL

Rewrite 설정

vim /etc/nginx/rewrite.rule

rewrite ^/html/index?$ /html/index.html last;

#/html/index.html 접근시 /html/index로 재작성

vim /etc/nginx/sites-available/default

server {

........................

include /etc/nginx/rewrite.rule #마지막줄에 추가

}

nginx -c /etc/nginx/nginx.conf -t #conf 검증

service nginx reload 또는 restart

빈 리스트
>>> a = [ ]
>>> a
[ ]


append를 이용한 리스트 추가
>>> a.append(1)
>>> a
[1]
>>> a.append("ABC")
>>> a
[1, 'ABC']


+ 연산자를 이용한 리스트 추가
>>> a += "DEF"
>>> a
[1, 'ABC', 'D', 'E', 'F']

>>> a += ["GHI"]
>>> a
[1, 'ABC', 'D', 'E', 'F', 'GHI']


instert를 이용해 리스트 끼워넣기
>>> a.insert(2, 'TEST')
>>> a
[1, 'ABC', 'TEST', 'D', 'E', 'F', 'GHI']

remove를 이용해 삭제하기
>>> a.remove('D')
>>> a
[1, 'ABC', 'TEST', 'E', 'F', 'GHI']


pop을 이용해 맨 마지막 삭제
>>> a
[1, 'ABC', 'TEST', 'E', 'F']
>>> a.pop(2)
'TEST'
>>> a
[1, 'ABC', 'E', 'F']


pop을 이용해 인덱스 값을 꺼내오면서 삭제
>>> a
[1, 'ABC', 'TEST, 'E', 'F']
>>> a.pop(2)
'TEST'
>>> a
[1, 'ABC', 'E', 'F']


len을 이용해서 크기 구하기
>>> a
[1, 'ABC', 'E', 'F']
>>> len(a)
4


index를 이용해서 찾기
>>> a
[1, 'ABC', 'E', 'F']
>>> a.index('E')
2


count
>>> a.count('A')
0
>>> a.count('ABC')
1


sort, reverse
>>> a.reverse()
>>> a
['F', 'E', 'ABC', 1]

>>> a.sort()
>>> a
[1, 'ABC', 'E', 'F']


extend 와 append
>>> a.extend("TEST")
>>> a
[1, 'ABC', 'E', 'F', 'T', 'E', 'S', 'T']

>>> a.append("TEST")
>>> a
[1, 'ABC', 'E', 'F', 'T', 'E', 'S', 'T', 'TEST']
