Package: ddclient
Version: 3.7.3-4
Severity: important
My smart ISP decided to do some really weird rapid ip changes:
Jan 18 14:17:14 dev ddclient[13901]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.173
Jan 18 14:20:39 dev ddclient[21237]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.42
Jan 18 14:25:43 dev ddclient[5889]: SUCCESS: updating my.host.name:

Jan 18 14:26:15 dev ddclient[5622]: SUCCESS: updating my.host.name:

Jan 18 14:27:15 dev ddclient[13901]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.173
Jan 18 14:30:40 dev ddclient[21237]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.42
This went on and on, soon resulting in:
Jan 18 22:26:20 dev ddclient[5889]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.130
Jan 18 22:26:27 dev ddclient[5622]: WARNING: skipping update of
my.host.name from xxx.xxx.xxx.130 to xxx.xxx.xxx.42.

Jan 18 22:37:53 dev ddclient[13901]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.173
And later:
Jan 19 06:41:51 dev ddclient[5622]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.42
Jan 19 06:41:51 dev ddclient[21237]: WARNING: updating my.host.name:
nochg: No update required; unnecessary attempts to change to the
current address are considered abusive
Jan 19 06:47:23 dev ddclient[5889]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.130
Jan 19 06:48:27 dev ddclient[13901]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.173
Jan 19 06:51:52 dev ddclient[5622]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.42
Jan 19 06:51:52 dev ddclient[21237]: WARNING: updating my.host.name:
nochg: No update required; unnecessary attempts to change to the
current address are considered abusive
Jan 19 06:57:23 dev ddclient[5889]: SUCCESS: updating my.host.name:
good: IP address set to xxx.xxx.xxx.130
And finally getting me blocked for abuse.
As you can see in the last part, the duplicate updates are simultaneous. When
I discovered this, there were *3* ddclient processes running.
My guess is the /etc/ppp/ip-up.d/ddclient script spawned a new ddclient process
while another one was running, and they kept about doing their business
without knowing of eachother. The 3rd process must've been the daemon,
which correctly detected the ip went back to its previously known value
(skipping update .. ).
Maybe it's a bug in ppp that makes the ip-up.d scripts run twice under weird
circumstances. Nevertheless, I think multiple ddclients should refuse running
for the same interface, or if they are somehow running, they should NOT
submit the same information (so i guess this is an upstream bug).
Or: another good idea might be to allow for absolutely enforcing the
daemon_interval across all ddclients running for the same interface, and make
this the default setting.
Regards
