Server only listens on IPv6 address

[Guy]

I installed rundeck using the official deb file, haven't changed any settings and started the server. However I wasn't able to reach the web interface at all. This is on an AWS instance, so I opened up port 4440 for 0.0.0.0/0 but still wasn't able to access it. I had a look at the output from netstat:

tcp6       0      0 :::4440                 :::*                    LISTEN      30914/java 

I'm able to SSH into the instance and this shows up as:

tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      488/sshd

So it looks to me like rundeck is only listening on the IPv6 address. How do I configure it to listen on the IPv4 address?

Thanks,
Guy

Guy, what distro/version is this? And what is localhost listed as in /etc/hosts?

Hi Moses,

The system is Ubuntu 11.10 (oneiric) and below is my hosts file:

127.0.0.1 localhost

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
# Added by cloud-init
127.0.1.1    domU-x-x-x-x-x-x.compute-1.internal domU-x-x-x-x-x-x

Thanks,
Guy

How odd. What is the rundeck command line as shown by ps? There seem to be a bunch of these binding-to-ipv6 and not ipv4 issues lately.

Here's the command from ps:

 Hi again Moses,

I worked out what the issue was. In framework.properties I changed server.hostname, server.name and server.url to the instance's public DNS, from localhost. It seems to be working now. It seems like it *is* actually listening on the IPv4 address but just didn't show in netstat.

Thanks for your help,
Guy
