Duplicate tries to update

Hi,

Since a while ddclient tries more than one time to update my domains. 
Since I'm having stability problems with my dsl-line I risk being locked 
out of zoneedit.com.

This is what I get at the second try :

WARNING:  file /var/cache/ddclient/ddclient.cache, line 4: Invalid Value 
for keyword 'ip' = '77.109.102.164/'
SUCCESS:  updating xxx.de-brouwerij.be: IP address set to 77.109.102.164 
(201: No records need updating.)

regards,
    ddclient <at> neptunus (version 3.8.0)

I do have two domains I update with ddclient, with different dns-services.

Is this a bug ?

Thanks,

Koenraad Lelong

Support for IPv6 (patch)

For some reason I cannot read all messages in this thread, but I would like
to second Eduardo's request for the new ipv6 feature.

>From the abundance of ipv6 addresses it may seem that 'ddclient' has no use
in the future, but that is not true.  Several ipv6 transition scenarios,
including Teredo, involve dynamic addresses (although no NAT).

One could, and perhaps should, use 'ddclient' for relaying corresponding
updates to dynamic DNS.

Eduardo's solution to separate ipv4 and ipv6 makes great sense, because one
can serve both protocols both from different equipment.  Many free hosting
plans provide only ipv4.  Serving ipv6, on the other hand, is uncomplicated
even when behind NAT and requires no port forwarding.

Hurricane Electric (he.net) offers dynamic DNS for A and AAAA records.  I
would like to use 'ddclient' for that purpose.

Sincerely,
Felix

If your interested in understanding the reasoning please check this old
discussion[1], with the relevant information from the FHS.  It's by no
means stupid.  Arguable maybe, not stupid.

sudo lives in /usr/bin!!  So this has nothing to do with it.  Please
check your assertions.

I'm using a teredo client (transition technology) so I get an dynamic
IPv6 over an IPv4 tunnel, I'd like to be able to access it.  I need a
name for that because doing:

ssh user@[2001:0000:4136:e378:8000:63bf:3fff:fdd2]

is not practical or, at least not so simple as:

ssh user@...

when you take into account that the host is miles aways from me, behind
a NAT router that changes its IPv4 address periodically.  I'm actually
(and happily) using a name for dynamic IPv6 right now.  So much for the
misconcept or contradiction.  IPv4 just would not work, or I would have
to setup a VPN for incoming connections ( and believe me it's a lot
easier to do apt-get install miredo, and that's it).

We found the misconcept and inner contradiction.  There it is.  Routing
and latency should ring an alarm with that idea of yours, not to mention

Support for IPv6 (patch)

Hi,

I wrote a little patch for 3.8.1 to support IPv6 on the two services I 
know that can handle it.  Both dyndns and freedns automatically 
recognize the type of address being passed to them and use it to update 
the A or the AAAA record.

I added the "usev6" variable, that works exactly as the "use" one.  So, 
if you are using dynds and change use/usev6 on your existing definition 
*and* you have a global IPv6 address you're all set.

For "usev6" only the "ip" and "if" strategies are implemented and the 
"if" one uses "ip -6 addr list" instead of "ifconfig" because I find it 
easier to parse and it doesn't need root privileges (Debian box).

So far the patch works for dyndns without problems, for an IPv6-only 
host (well, it does have IPv4 but its a private address, the IPv6 
address is public and comes from miredo/teredo).

Since the program hashes the hosts on the dynamic domain, it is not 
possible to update IPv4 and IPv6 on the same service with the same 
configuration file.  I'm not that fluent in perl so I guess it's better 
for the actual programmers to sort that one out.

Freedns forces you to have an IPv4 record that is used to build the 
update url.  The IPv6 update on that url works but the DNS servers can 
take a long time to notice it.  It's tricky.

I hope it helps somebody, it took me a while to figure it out.

Is there a way to have ddclient force an update once a day?

Dyndns doesn't like spurious updates (indication of abuse of free
accounts), but if you don't update at least once a month, your account
gets suspended.

So I was wondering if there was a way to configure ddclient to do this.

I suppose I could set up a cron job that would stop the daemon once a
day, do a -force update, and then restart the daemon, but I was hoping
there was a way to do all of this with ddclient running as daemon.

Any thoughts?

Re: Log file

Thanks for the reply, I want to check if the service is log in well on
the dyndns server.

Something on /var/log/ddclient.log

Best regards.
