Package: cfengine3
Version: 3.12.1-2
Severity: normal
Tags: ipv6
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
installed cfengine3 and configured it on a raspberry pi, and also
configured a client correctly via ipv4. Bootstrap to ipv4 address of
server worked. Tried to bootstrap a client to the ipv6 address of the
server but it failed...
* What exactly did you do (or not do) that was effective (or
ineffective)?
Tested ipv6 via recommendation online at cfengine site:
https://docs.cfengine.com/docs/3.5/reference-components-cfserver.html
nc -v -6 raspberrypi.lan 5308
nc: connect to raspberrypi.lan port 5308 (tcp) failed: Connection refused
nc: connect to raspberrypi.lan port 5308 (tcp) failed: Connection refused
In wireshark I see that as soon as the syn packet is sent, the server
sends a RST,ACK packet refusing the connection
* What outcome did you expect instead?
Connect should have worked, and bootstrapping to the ipv6 address of the
server should have worked.
note also that the server has this in the inputs/controls/cf_serverd.cf
file:
# Bind to all interfaces including ipv6
# Adding this on windows will force ipv6 only
bindtointerface => "::";
so it should be binding to ipv6 and
sysctl:
net.ipv6.bindv6only = 0
so it should accept ipv4 and ipv6 on this socket.
