network 7.0.20 as well
from noip-rfc2136.
If I handcraft the HTTP request it works.
from noip-rfc2136.
Ok, so I had this when I investigated on 7.0.21
The underlying process that does the work on the UDM is inadyn
: https://github.com/troglobit/inadyn , so this hasn't changed from 6.x.x.
Config looked valid:
#
# Generated automatically by ubios-udapi-server
#
iface = ppp0
custom 192.168.1.1:1 {
hostname = "example.com"
username = "user"
password = "pass"
ddns-server = "192.168.1.1"
ddns-path = "/\/nic/update?hostname=%h&myip=%i"
}
I tried killing the process with kill -15 $(pidof inadyn)
, process restarted automatically, but then didn't make any sort of request on restart. Checked the cache dir /.inadyn/
, no cache file there. Usually it caches the IP when it updates to prevent useless requests.
Running the process manually with /usr/sbin/inadyn -n -s -C -f /run/ddns-ppp0-inadyn.conf -1 -l debug --foreground
worked as expected, got a request to the python process:
inadyn[25720]: In-a-dyn version 2.8.1 -- Dynamic DNS update client.
inadyn[25720]: Cached IP# 198.51.100.2 for example.com from previous invocation.
inadyn[25720]: Last update of example.com on Wed Feb 9 13:47:27 2022
inadyn[25720]: Base64 encoded string: TW92ZSBhbG9uZywgbm90aGluZyB0byBzZWUgaGVyZQ==
inadyn[25720]: Get address for custom
inadyn[25720]: Checking for IP# change, querying interface ppp0
inadyn[25720]: Checking IPv4 address 198.51.100.2 ...
inadyn[25720]: IPv4 address 198.51.100.2 is valid.
inadyn[25720]: IPv6 address disallowed, enable with 'allow-ipv6 = true'
inadyn[25720]: Invalid/local address fe80::4144:cfea:dead:beef for ppp0, skipping ...
inadyn[25720]: Checking IPv4 address 198.51.100.2 ...
inadyn[25720]: IPv4 address 198.51.100.2 is valid.
inadyn[25720]: No IP# change detected for custom, still at 198.51.100.2
Interestingly, this created a cache file in /.inadyn/
. Deleted the cache file and tried killing the resident inadyn
process again, and it made a request properly.
I'm still not sure what the root cause is, perhaps something in the update didn't quite migrate properly, but I seem to have rectified it by running /usr/sbin/inadyn -n -s -C -f /run/ddns-ppp0-inadyn.conf -1 -l debug --foreground
on the UDM, then deleting the cache in /.inadyn/
, and then forcing a restart of the inadyn
process with kill -15 $(pidof inadyn)
. Might work for you?

Quick question before I go chase this.... Does this make requests for ALL DHCP addresses or just the UDMPro's interface(s)?
from noip-rfc2136.
Just if the IP on the UDM's WAN interface changes I believe.
from noip-rfc2136.
👎
I'm looking for a solution that updates my DNS server RFC-2136 for EVERY DHCP address given out, IPv6 & IPV4.
My WAN interface hasn't changed in 4 years.
from noip-rfc2136.
Whilst not entirely beyond the scope of this project, it's not what it was created for. The 'Dynamic DNS' configuration in the UDM is definitely within the 'Internet' section of setting in the Network application, which is why I thought you were asking about that.
Regarding what you want to do: UDM seems to use dnsmasq
for DHCP and DNS. There is a dhcp-script
option in the dnsmasq
configuration that you could use to achieve what you're looking for, but your changes would be temporary until it was overwritten by ubios-udapi-server
which seems to manage the configuration files. Until UI give the option to specify a DNS server to update (unlikely!), your best bet is probably turning off DHCP in UDM and running your own instance of dhcpd
from isc-dhcp-server
and configuring it to do the DDNS updates you want.
