python shell根据ip获取主机名代码示例

> import socket
> socket.gethostbyname("www.baidu.com")
'61.135.169.125'
> socket.gethostbyname("rs.xidian.edu.cn")
'202.117.119.1'

def getHostName(ip):
  command = 'java -jar %s %s "hostname > %s.hostname"' %(remoteCmdLoca,ip,ip)
  result = subprocess.call(command, shell=True)
  command = '%s -q -r -pw passwd %s root@%s:/root' % (pscpLoca, pscpLoca, ip)
  result = subprocess.call(command, shell=True)
  command = '%s -q -r -pw passwd root@%s:/root/%s.hostname %s' %(pscpLoca,ip,ip,fileDir)
  result = subprocess.call(command, shell=True)
  fileName = fileDir + ip + '.hostname'
  readFile = open(fileName,'r')
  hostnameInfo = str(readFile.readline().strip('\n'))
  readFile.close()
  subprocess.call('rm '+ fileName, shell=True)
  print "=========%s hostname is %s========" %(ip,hostnameInfo)
  return hostnameInfo

import socket
hostName = socket.gethostname()

 import socket
> hostName = socket.gethostname()
> print hostName
