Lookup from threads
|
|
==============================
|
|
|
|
This example shows how to use unbound module from a threaded program.
|
|
In this example, three lookup threads are created which work in background.
|
|
Each thread resolves different DNS record.
|

#!/usr/bin/python
|
|
from unbound import ub_ctx, RR_TYPE_A, RR_CLASS_IN
|
|
from threading import Thread
|
|
|
|
ctx = ub_ctx()
|
|
ctx.resolvconf("/etc/resolv.conf")
|
|
|
|
class LookupThread(Thread):
|
|
def __init__(self,ctx, name):
|
|
Thread.__init__(self)
|
|
self.ctx = ctx
|
|
self.name = name

def run(self):
|
|
print "Thread lookup started:",self.name
|
|
status, result = self.ctx.resolve(self.name, RR_TYPE_A, RR_CLASS_IN)
|
|
if status == 0 and result.havedata:
|
|
print " Result:",self.name,":", result.data.address_list

threads.append(thread)
