get hostname and ip

Windows 主机名IP地址：

#!C:\\python26\\python.exe

# -*- coding:UTF-8 -*-

import socket

# 主机名
name = socket.gethostname()
print name

# 主机名（带域的后缀）
myfullname = socket.getfqdn(socket.gethostname())
print myfullname

# IP 地址
ip_addr = socket.gethostbyname(name)
print ip_addr

# 主机名和IP地址（多网卡）
socket.gethostbyname_ex(socket.gethostname())

Linux 主机名IP地址：

#!C:\\python26\\python.exe
# -*- coding:UTF-8 -*-

import socket
import fcntl
import struct

def get_ip_address(ifname):
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    return socket.inet_ntoa(fcntl.ioctl(
        s.fileno(),
        0x8915,
        struct.pack('256s', ifname[:15])
    )[20:24])

print "LoopBack Addr: " + get_ip_address('lo')
print "My IP Address: " + get_ip_address('eth0')

Windows 用命令过滤网卡信息：

#!C:\\python26\\python.exe
# -*- coding:gbk -*-
