netatalk can't communicate with cnid back-end

K

Khaine

Netatalk has stopped working on a server that I support for my parents. I'm not sure what has changed to cause it. From my investigation it looks like getaddrinfo() cannot lookup localhost

This is an extract from /var/log/netatalk.log that shows that netatalk can't connect to the CNID backend due to being unable to resolve localhost

I can ping localhost and host works


% ping localhost
PING localhost (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.040 ms
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.060 ms



% host localhost
localhost has address 127.0.0.1


However if I use python's interactive prompt getaddrinfo clearly doesn't return the right value

Code: 
>>> import socket
>>> socket.getaddrinfo('localhost',4077)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
socket.gaierror: [Errno 8] hostname nor servname provided, or not known
>>> socket.getaddrinfo('127.0.0.1',4077)
[(2, 2, 17, '', ('127.0.0.1', 4077)), (2, 1, 6, '', ('127.0.0.1', 4077)), (2, 5, 132, '', ('127.0.0.1', 4077))]
>>> socket.getaddrinfo('www.google.com','www')
[(2, 1, 6, '', ('150.101.161.236', 80))]

/etc/hosts is configured as:

Code: 
127.0.0.1               localhost localhost.my.domain


/etc/nsswitch.conf is configured as

Code: 
#

I'm running freebsd-10.3-RELEASE and netatalk version 3.1.10


% freebsd-version
10.3-RELEASE-p14
% netatalk-config --version
3.1.10



I'm not sure why getaddrinfo() can't resolve localhost, but can resolve other hosts. Can anyone help me understand what might be misconfigured.

Many thanks
