Public bug reported:
Binary package hint: gnome-utils
I installed a local dictionary server to be able to work off-line. I
added a new source in gnome-dictionary with the following settings:
name : local
hostname: localhost
port: 2628
I selected the local source and tried a lookup. Instead of a definition,
I got:
Fout bij het opzoeken van de definitie
Verbinding mislukt voor de woordenboekserver op localhost:2628
(Which translates to 'error looking up definition; connection failure
for dictionary server on localhost:2628')
Further information:
- the local dictionary server is running and allows local connections
- I tested the local connection with telnet and got a working connection
- a tcpdump on the loopback interface shows what might be the cause:
tcpdump -i lo
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on lo, link-type EN10MB (Ethernet), capture size 96 bytes

So it seems a IPv6 connection was attempted. dictd will not work on
IPv6.
The contents of /etc/hosts:
127.0.0.1 localhost
127.0.1.1 camilla
# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
It seems that only ::1 was attempted. When I try telnet localhost I get:
telnet localhost dict
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 camilla dictd 1.10.11/rf on Linux 2.6.28-15-generic <auth.mime>
<8.9063.1253183...@camilla>
It seems telnet tries ::1 first, then 127.0.0.1.
Finally, changing the source settings in gnome-dictionary to use
'127.0.0.1' instead of 'localhost' resolved the issue.
