Description:
so i found this out as i put in an incorrect ipv6 for ssl1005 and ssl1006 - however they health checked fine... though when traffic was sent to them, it was sent ot the incorrect ipv6 address. it appears that the health checks are all ipv4, even when it's an ipv6 vip. some sort of knowledge or ability to specify ipv4 versus ipv6 health checks would be preferred.
please let me know if this is better suited for bugzilla

Mentioned in SAL (#wikimedia-operations) [2017-07-12T16:14:45Z] <ema> downgrade pybal to 1.13.6 on lvs1010 T82747 T154759 (1.13.7 throwing exceptions)
Almost there! I had to downgrade pybal to 1.13.6 on lvs1010 because of the following exception:
File "/usr/lib/python2.7/dist-packages/twisted/names/dns.py", line 2776, in _query writeMessage(m) File "/usr/lib/python2.7/dist-packages/twisted/names/dns.py", line 2896, in writeMessage self.writeMessage(m, address) File "/usr/lib/python2.7/dist-packages/twisted/names/dns.py", line 2824, in writeMessage self.transport.write(message.toStr(), address) File "/usr/lib/python2.7/dist-packages/twisted/internet/udp.py", line 295, in write addr[0], "IPv4 port write() called with IPv6 address")
The problem can be reproduced with:
import sys from twisted.names import client from twisted.internet import task def printit(result): print result def main(reactor, hostname): #ip = "208.80.154.50" ip = "2620:0:861:1:208:80:154:50" resolver = client.createResolver([(ip, 53)]) deferred = resolver.lookupIPV6Address(hostname, timeout=[5]) deferred.addCallback(printit) return deferred task.react(main, sys.argv[1:])
Using 208.80.154.5 instead of 2620:0:861:1:208:80:154:50 the script works.
That's a twisted bug mentioned here https://matrix.org/jira/browse/SYN-254.
