Hello

This problem seems to be present in 3.8.0 as I can reproduce it several times.
I use web checkip on dyndns.org

The daemon is stuck just after it sends the http request :
# ps aux |grep ddclient
root     26917  0.0  2.1  10620  5584 pts/0    S    08:13   0:00 ddclient -
reading from checkip.dyn

Here are my /var/log/messages :

Aug 16 08:25:57 secure ddclient[26917]: CONNECT:  checkip.dyndns.org
Aug 16 08:25:57 secure ddclient[26917]: CONNECTED:  using HTTP
Aug 16 08:25:57 secure ddclient[26917]: SENDING:  GET / HTTP/1.0

Aug 16 08:25:57 secure ddclient[26917]: SENDING:
... and nothing more...

It seems to be related to bug #2113169
https://sourceforge.net/tracker/?func=detail&aid=2113169&group_id=116817&atid=67

Thanks for replying so quick.

My daemon runs every 60s but I only use dyndns.org to check my IP so dyndns
does not block anything.
I update my dns on ovh.com but it's not the problem as ddclient does not update
if the cache matches the IP address. This is fine.

The problem is that sometimes, the web page checkip.dyndns.org  does not reply
well (I am pretty sure it's because of our ISP here in French Polynesia that
does have a transparent proxy, but we cannot do anything at this level...)

Sometimes, the system timeout (180s for me) does well the job and ddclient does
not freeze. Here are the logs  to illustrate that behaviour :
Aug 16 11:05:15 secure ddclient[30159]: CONNECT:  checkip.dyndns.org
Aug 16 11:05:15 secure ddclient[30159]: CONNECTED:  using HTTP

Aug 16 11:08:16 secure ddclient[30159]: WARNING:  unable to determine IP

But sometimes, the timeout does not work...

Here are my last logs before the daemon freezed again. Now it's 11:27, it's
been 10 minutes it's stucked.

... and that's it

Here's my conf file :
daemon=60                               # check every 60 seconds
syslog=yes                              # log update msgs to syslog
mail=root                               # mail all msgs to root
mail-failure=root                       # mail failed update msgs to root
pid=/var/run/ddclient.pid               # record PID in file.
ssl=yes                                        # use ssl-support.  Works with
verbose=yes
debug=yes
timeout=20
use=web
protocol=dyndns2
server=www.ovh.com
login=invitu.com-easypme
password=*******
pf-easypme.invitu.com

the full result of `ddclient -daemon=0 -debug -verbose -noquiet`  does not show
more logs.
Do you think you would still need it ? (it's hard to catch it as the problem
occurs randomly and I must wait 3 minutes to check if the timeout works or not)

PS: I tried with the last svn rev111, same thing
I tried the modification found in the bug 2113169 but I have a segfault...
Actually, the only solution I found is to restart ddclient every hour which
is not elegant...

Regards

You get blocked because of your 60 seconds: see
http://www.dyndns.com/developers/checkip.html for more information.  As they
say on the bottom of the place: Checks must be spaced 10 minutes apart to help
reduce server load.

Humm, you're right... thank you !

By the way, ddclient should not freeze like that, timeout should do its job,
don't you think so ?

I guess that if I want to have more reactivity for my IP change, I should check
my IP on my router status webpage...
I have a linksys WAG200G, I added the corresponding status page in ddclient :

     'linksys-wag200g'        => {
                                 'name' => 'Linksys WAG200G FW',
                                 'url'  => '/setup.cgi?next_file=Status.htm',
                                 'skip' => 'IP Address:',
                               },


Regards

Could you please post the full result of  `ddclient -daemon=0 -debug -verbose
-noquiet` and try to understand the logging. If you don't understand or find
an error, post your config and the result on http://ddclient.pastebin.ca and
post a link here.  If you have a daemon setting less than 600, your just blocked
by dyndns.
