Hi,

A subtle problem. Golfed down to;

my IO​::Socket​::INET $sock;
$sock .= new( :host<localhost>, :port(65010));

Error thrown
Failed to connect​: connection refused
  in block <unit> at Tests/sock.pl6 line 8

  * On my laptop it works without error as well as on Travis-ci. On
  another system with the same linux distribution and version, it
  gives the above error.
  * On both systems localhost translates to 127.0.0.1 (checked with dig)
  * The firewall is not blocking, checked by turning it off.
  * On the system with the error I've changed 'localhost' into 127.0.0.1
  after which no error is thrown.

perl version on systems are 2016.05-31-g0873fd7 (on ok system) and
2016.05-25-gc5dfd77. On other curious thing is both systems say that
they are `Already up-to-date` using git pull while versions differ.

Note that dig only tells you what DNS returns, not what a query through NSS
returns; use "getent hosts" for that. In particular, it will not tell you
how /etc/hosts affects things.
(I would suspect that, on the failing system, localhost first resolves to
:​:1 and IPv6 is not configured.)

getent hosts on faulty system
127.0.0.1 localhost localhost.localdomain localhost4
localhost4.localdomain4
127.0.0.1 localhost localhost.localdomain localhost6
localhost6.localdomain6

On ok system. It differs only in the second line

127.0.0.1 localhost localhost.localdomain localhost4
localhost4.localdomain4
127.0.0.1 localhost6 localhost6.localdomain6

I've removed the localhost localhost.localdomain part from the second
line in /etc/hosts and after that the test went ok. So this was really a
quick fix.

Thanks,

Does this mean that the current IO​::Socket​::INET bahavior is fine and the ticket can be closed?

Hi,
Yes you can close it.

Thanks,
