Hi.
I need to try to write a simple xfr client, which i am gonna use it to count
resource records of TLD zones.
I wrote a simple xfr client code..... here is my code....
# zone_list contains list of zones for xfr details
# dns_server contains BIND or NSD ip
for xtld_zone in zone_list:
try:
z = dns.zone.from_xfr(dns.query.xfr(dns_server,tld_zone)) # this
dns.query.xfr will return a generator, we are converting it to a generator.
# if ns record then
total = 0
ns_record = []
for (name, rdataset) in z.iterate_rdatasets(dns.rdatatype.ANY):
if name != dns.name.empty:
total += len(rdataset)
except BadResponse:
# handle exception
except UnexpectedSource:
# handle exception
but i want to know, is there any other better way to do this.?
if its can you explain me.
Thanks and Regards,
Shan
