dnspython update dns record issue - stamnik - Mar-02-2017
I'm trying to use dnspython to do a TSIG based dynamic DNS update.
I've followed the example code :
#!/usr/bin/env python
import sys
import dns.update
import dns.query
import dns.tsigkeyring
keyring = dns.tsigkeyring.from_text({
'keyname.' : 'VarFF=2Xts7T5Vb/xd&8ir=='
})
update = dns.update.Update('domain_name', keyring=keyring)
update.replace('myserver', 30, 'a', '88.88.88.88')
response = dns.query.tcp(update, 'dns_ip',timeout=10)and here is what I got:
response = dns.query.tcp(update, 'dns_ip',timeout=10) File "/root/bck/dnspython/dns/query.py", line 475, in tcp q.keyring, q.mac) File "/root/bck/dnspython/dns/query.py", line 412, in receive_tcp one_rr_per_rrset=one_rr_per_rrset) File "/root/bck/dnspython/dns/message.py", line 821, in from_wire reader.read() File "/root/bck/dnspython/dns/message.py", line 749, in read self._get_section(self.message.additional, adcount) File "/root/bck/dnspython/dns/message.py", line 701, in _get_section self.message.first) File "/root/bck/dnspython/dns/tsig.py", line 198, in validate raise BadSignature dns.tsig.BadSignature: The TSIG signature fails to verify.

http://www.dnspython.org/examples.html Wrote:import dns.query
import dns.tsigkeyring
import dns.update
import sys
keyring = dns.tsigkeyring.from_text({
'host-example.' : 'XXXXXXXXXXXXXXXXXXXXXX=='
})
update = dns.update.Update('dyn.test.example', keyring=keyring)
update.replace('host', 300, 'a', sys.argv[1])
response = dns.query.tcp(update, '10.0.0.1')Why is your key ring's value "keyname", instead of "host-example." like in the example? I'm not sure what the lib is supposed to do, so I don't know if those values are valid or not...
