[KEDUIT] 클라우드 컴퓨팅과 보안솔루션을 활용한 DC 엔지니어 양성교육 - Day54

1. 서론

    오늘은 파이썬 수업 마지막이었다.

2. 본론

1. Python

# 1. Sort
import operator

trainDic = {'Tomas':'토마스', 'Edward':'에드워드', 'Henry':'헨리', 'Gothen':'고든', 'James':'제임스'}

trainList = sorted(trainDic.items(), key=operator.itemgetter(0))

print(trainList)

# 2. 사전형 활용
foodMatching = {'파전':'전통주', '치킨':'맥주', '삼겹살':'소주', '피자':'와인'}

while(True):
    choice=input(str(list(foodMatching.keys())) + '중 좋아하는 음식은? \n 끝내고 싶으면 "끝" 을 입력해주세요. ')
    if choice in foodMatching.keys():
        print(f'{choice}과 궁합이 좋은 술은 {foodMatching[choice]}입니다.')
    elif choice == '끝':
        break
    else:
        print('선택하신 음식은 궁합 리스트에 없습니다. 다시한번 확인해 보세요')

# 3. set
myset = {1, 2, 3, 3, 3, 4, 4}
print(myset)
myset = [1, 2, 3, 3, 3, 4, 4]
print(myset)
print(set(myset))
myset1 = {1, 2, 3, 4}
myset2 = {4, 5, 6, 7}
# 교집합
print(myset1 & myset2)
# 합집합
print(myset1 | myset2)
# 차집합
print(myset1 - myset2)
# 대칭차집합
print(myset1 ^ myset2)

# 4. List Comprehension
numList = [num for num in range(1,101) if num % 3 == 0]
print(numList)

# 5. Zip
num1 = ['1', '2', '3', '4', '5', '6']
num2 = ['7', '8', '9']
tupList = list(zip(num1, num2))
dic = dict(zip(num1, num2))
print(tupList)
print(dic)

# 6-1. Shallow copy(메모리 공유)
num1 = ['1', '2', '3', '4', '5', '6']
num3 = num1
num3[0] = 10
num3.append(100)
print(num1)

# 6-2. Deep copy
num1 = ['1', '2', '3', '4', '5', '6']
num3 = num1[:]
num3[0] = 10
num3.append(100)
print(num1)
print(num3)

# 7. 함수활용
ss = "이제곧주말"
sslen = len(ss)
for i in range(0, sslen):
    print(ss[i] + "$", end='')

# 8. 로또
import random
def getNum():
    return random.randrange(1, 46)

lotto = []
num = 0

while True:
    num = getNum()

    if lotto.count(num) == 0:
        lotto.append(num)

    if len(lotto) >= 6:
        lotto.sort()
        break

print(f"추첨된 로또 번호는 {lotto}입니다.")

# 9. Python with mysql
import pymysql

con, cur = None, None
memberID, memberName, memberAddress = "", "", ""
sql = ""

con = pymysql.connect(
    host="127.0.0.1",
    user="root",
    port=3306,
    passwd="1234",
    db="shopdb",
    charset="utf8")
cur = con.cursor()

while True:
    memberID = input("사용자ID : ")
    if memberID == '':
        break
    memberName = input("사용자이름 : ")
    memberAddress = input("사용자주소 : ")

    sql = f"INSERT INTO memberTbl VALUES ({memberID}, {memberName}, {memberAddress})"
    cur.execute(sql)

con.commit()

cur.execute("SELECT * FROM memberTbl")

while True :
    row = cur.fetchone()
    if row == None :
        break
    memberID = row[0]
    memberName = row[1]
    memberAddress = row[2]
    print(f"{memberID}, {memberName}, {memberAddress}")

con.close()

2. Network

1. privilege 레벨별 명령어 설정
//ASW1
# line c 0
# no privilege level 15
!
# enable secret ccie
# enable secret level 2 ccie2
# enable secret level 3 ccie3
# privilege exec level 2 show running-configure
# privilege exec level 3 configure terminal
# privilege exec level 3 interface
# privilege exec level 3 ip address

2. 콘솔 로그인시 유저네임 설정
# line c 0
# login local
!
# username admin2 privilege 2 password ccna2

3. telnet 접속시 유저네임 설정
# vlan 230
!
# int vlan 230
# ip add 192.168.10.11 255.255.255.0
!
# line vty 0 4
# login local

4. SSH
//DSW1
# ip domain-name kedu.edu
# crypto key generate rsa
# ip ssh version 2
!
# line vty 0 4
# transport input ssh
# login local
!
# line c 0
# login local
!
# username admin password cisco

5. AAA(Authentication, Authorization, and Accounting) with TACACS+
//Win2016
Administration Control -> admin -> Set Password + Grant all -> submit
Network Configuration -> Add AAA Client -> Authenticate using(TACACS+) + Single Connect TACACS+ AAA Client

//DSW1
# aaa new-model
# tacacs-server host 192.168.50.103 single-connection key 1234
# aaa authentication login default tacacs+ group local
!
# test aaa group tacacs+ admin100 1234 legacy
!
# no aaa authentication login default group tacacs+ group local
# aaa authentication login VTY_ACC group tacacs+ group local
!
# line vty 0 4
# login authentication VTY_ACC
# username admin15 privilege 15 password cisco123
!
# aaa authorization exec VTY_PRI group tacacs+ local
# aaa authorization command 15 VTY_PRI group tacacs+ local
!
# line vty 0 4
# authorization exec VTY_PRI
# authorization commands 15 VTY_PRI

//Win2016
Interface Configuration -> TACACS+ -> Shell(exec) on User(Check)
Interface Configuration -> Advanced Options -> Per-user TACACS+/RADIUS Attributes(Check)
User Setup -> admin100 -> TACACS+ Settings -> Shell(exec) + Privilege level(15)
                       -> Shell Command Authorization Set -> Per User Command Authorization(permit)
User Setup -> monitor -> command에 체크하고 configure 추가

//DSW1
# aaa accounting exec ACC start-stop group tacacs+
# aaa accounting commands 15 ACC start-stop group tacacs+
!
# line cty 0 4
# accounting exec ACC
# accounting commands 15 ACC

    벌써 주말이다.
