Duplicate tries to update

Koenraad Lelong — 2012-05-09T16:14:13

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)

Felix Lechner — 2011-10-31T18:13:14

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.

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 think I'd rather go back to ddclient, your knowledge or assumptions on
Debian and sane defaults and usability seem to be a little ... either
biased or outdated, just like the previous IPv6 ones.  I just said a
normal user in Debian does not have /sbin by default in the path.
Ddclient *runs as root*.  So that's not a problem!


For each entry, yes, that is the whole idea.  To treat ipv6 hosts as
another host.  For me it's hard to pretend it's like an MX or something
like that and add a parameter.  It's hard because there is all the
strategy stuff.


Yes, by adding two configuration entries.


I started out the way you are suggesting.  But I really didn't like the
idea of namespace pollution, if you see what I mean.  "ifv6", "ipv6

Re: Support for IPv6 (patch)

Eduardo Trápani — 2011-09-12T13:18:43

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< at >[2001:0000:4136:e378:8000:63bf:3fff:fdd2]

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

ssh user-YyWObjc/euz1C6oaWVhzKtls0Zm15Pq+< at >public.gmane.org

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
routing size tables.  If you fly from the US to France, even if possible
(as with IPv4) I doubt you would want to keep "your own" IPv6 a

Support for IPv6 (patch)

Eduardo Trápani — 2011-09-10T05:09:16

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 pe

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

Wim Vinckier — 2011-09-06T19:47:05

There is the max-interval for that.  By default ddclient updates
dyndns every max-interval time which defaults to 25 days.


Yep, I think the last one is a very bad idea. :-)

Is there a way to have ddclient force an updateonce a day?

Cary Lewis — 2011-09-06T18:00:54

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?

Hi Josu,

The IO::Socket::INET library tries to resolve the host
name 'checkip.dyndns.org' into an IP address and that fails.
Probably, you are starting ddclient early in the boot process
before you have name resolution up and running.

Make sure that while booting, you start the various services
in a good order, and don't start anything before the required
prerequisites are working.  In particular, first start up your
interfaces - dial-in, probably? - then start up the DNS resolver
(which may be automatic, some PPP and some DHCP client programs
automatically create the file /etc/resolv.conf when receiving the
necessary information from the peer) and only start ddclient when
you are sure that DNS resolution is working properly, in particular
that /etc/resolv.conf is in place and contains working name
server adresses of your Internet service provider.

How to achieve that in detail is outside the scope of this list,
ask the supplier of your PPP,

Wim Vinckier — 2011-05-21T08:19:14

I've tried some others but most have give errors to.  Btw, how fast do
you run ddclient?  There is a rate limit for the service so there is a
possibility you get blocked by there service.
In my experience the best thing you can do is getting your IP from your router.

wim.

ddclient debug advice

Dennis Putnam — 2011-03-21T22:20:02

I have a 'ddclient' that only updates 'dnydns.com' when I enter
'ddclient stop' and 'ddclient start'. I get nothing in my syslog at all
(good or bad) and I don't know how to go about debugging this. For
reference here is my redacted 'ddclient.conf' which was generated by the
dyndns.com web site.

## ddclient configuration file
daemon=300
# check every 300 seconds
syslog=yes
# log update msgs to syslog
mail-failure=mymail-3t13RrdZcR7QT0dZR+AlfA< at >public.gmane.org # Mail failed updates to user
pid=/var/run/ddclient.pid
# record PID in file.
## Detect IP with our CheckIP server
use=web, web=checkip.dyndns.com/, web-skip='IP Address'
## DynDNS username and password here
login=uuuuuuuuuu
password=ppppppppp
## Default options
protocol=dyndns2
server=members.dyndns.org
## Dynamic DNS hosts
myhost1.dyndns-ip.com,myhost2.dyndns-ip.com

Any advice as to how to debug this would be appreciated.

Yes, ddclient is not famous for its documentation.
As a general rule, your best bet for understanding what the
program does is reading the source code, even though that's
rather entangled and not easy to understand due to all those
global variables.


Judging from the function geturl(), my impression is that ddclient
plainly doesn't support proxies that require authentication.
In the function geturl(), i see the DynDNS credentials being passed
on to the DynDNS server, but i don't see any variables that could
hold proxy credentials.


Oh, you mean into the "proxy" configuration variable?
I don't think that will work, here is the parser for that
variable, you find it in geturl():

    $proxy  =~ s%^https?://%%i;
    $peer   = $proxy || $server;
    $peer   =~ s%/.*%%;
    $port   = $peer;
    $port   =~ s%^.*:%%;

William Oquendo — 2010-06-10T23:52:27

Dear all, I have been searching in google and in the forums with no success
about the following: I have a computer behind a University proxy, and I need
to know the internal ip all the time. I need to specify the CREDENTIALS for
a proxy in ddclient, since I always get error 407 proxy authentication
error.
I have already configured the proxy in both the command line and the
ddclient.conf file, but I always got the error 407, proxy authentication
required. In a desperate try, I wrote the full line for the proxy:
userproxy:passwordproxy< at >proxy.this.edu:8080
and ddclient quits an  error message related to "Error connecting to proxy
userproxy:8080" !!
Even the http_proxy var is present.

I really appreciate your help. I just simply want to know how to configure
the proxy credentials in ddclient.

Thanks in advance.
