1.打印本机设备名以及IPv4地址
#!/usr/bin/python2.7
# -*- coding=utf-8 -*-
import socket
def print_machine_info():
host_name = socket.gethostname() #本机设备名
ip_address = socket.gethostbyname(host_name) ＃设备名对应的ip 地址
print "%s \‘s ip is %s" % (host_name,ip_address) ＃打印
if __name__ == ‘__main__‘:
print_machine_info()
2.获取远程设备的IP地址信息
＃!/usr/bin/python2.7
import socket
def print_machine_info():
remote_hostname = ‘www.baidu.com‘
try:
print "%s \‘s ip is %s" % (remote_hostname,socket.gethostbyname(remote_hostname))
except socket.error, err_msg:
print "%s: %s" %(remote_hostname, err_msg)
if __name__ == ‘__main__‘:
print_machine_info()
3.计算cisco无线AP需要dhcp的option43
#/usr/bin/python2.7
# -*- coding=utf-8 -*-
import socket
from binascii import hexlify
import sys
def wlc_option43_hex():
wlc_number = raw_input(‘Enter the wlc number:‘)
if wlc_number == ‘1‘:
put_number = raw_input(‘Enter the wlc ip:‘)
for ip_addr in [put_number]:
wlc_ip_addr = socket.inet_aton(ip_addr)
unpacked_ip_addr = socket.inet_ntoa(wlc_ip_addr)
hex_prefix = ‘f104‘
print "IP Address: %s => option43 hex %s"\
%(unpacked_ip_addr,str(hex_prefix)+hexlify(wlc_ip_addr))
else:
while True:
put_number = raw_input(‘Enter the wlc ip:‘)
if put_number!= ‘q‘:
for ip_addr in [put_number]:
wlc_ip_addr = socket.inet_aton(ip_addr)
unpacked_ip_addr = socket.inet_ntoa(wlc_ip_addr)
hex_prefix = ‘f108‘
print "IP Address: %s => option43 hex %s"\
%(unpacked_ip_addr,str(hex_prefix)+hexlify(wlc_ip_addr))
else:
sys.exit()
if __name__ == ‘__main__‘:
wlc_option43_hex()
效果：
当无线控制器的数量为1时：
Enter the wlc number:1
Enter the wlc ip:10.10.9.252
IP Address: 10.10.9.252 => option43 hex f1040a0a09fc
当无线控制器的数量为2时：
Enter the wlc number:2
Enter the wlc ip:10.10.8.252
IP Address: 10.10.8.252 => option43 hex f1080a0a08fc
Enter the wlc ip:10.10.123.252
IP Address: 10.10.123.252 => option43 hex f1080a0a7bfc
Enter the wlc ip:q
