一、函式

1.socket.gethostname():不帶任何引數，返回一個字串（主機名），通常不完整。比如csm.example.com 只會返回csm

2.socket.getfqdn():帶一個引數，返回完整主機名

二、程式碼

import sys,socket

def getipaddrs(hostname):
	"""Given a host name,perform a standard (forward) lookup and return a list of ip addressfor that host."""
	result=socket.getaddrinfo(hostname,None,0,socket.SOCK_STREAM)
	return [x[4][0] for x in result]

#calling gethostname() returns the name of the local machine
hostname=socket.gethostname()
print "hostname is:",hostname

#try to get the fully qualified name:
print "Fully_qualified name:",socket.getfqdn(hostname)
try:
	print "IP address:", ", ".join(getipaddrs(hostname))
except socket.gaierror,e:
	print "error"

三、執行結果

[[email protected] testpython]# python host.py 
hostname is: csm
Fully_qualified name: dragoneyes-PC.workgroup
IP address: 192.168.155.9
