This provider implementation uses sparsely documented details of the
their updating mechanism. The only reference to passing in IP addresses
via GET parameters I could see was in the german version of the dynamic
DNS tutorial, where they showed it as part of a FRITZ!Box setup example.
This fixes caching issues when using the 'usev4' or 'usev6' parameters.
Without this, the "min-interval" and "warned-min-interval" limits will
not work.
For the legacy 'use' parameter, the wrapping code takes care of
translating 'status-ipv*' to 'status'.
With this change, any config value may be set through an environment
variable by appending '_env' to the keyword (i.e. 'password_env' instead
of 'password') and setting the value to the name of the environment
variable that contains the actual configuration value.
This allows keeping sensitive info (i.e. login and password)
out of the configuration file.
Example configuration snippet:
protocol=namecheap, \
server=dynamicdns.park-your-domain.com, \
login_env=DD_LOGIN, \
password_env=DD_PASSWORD \
@
With this configuration snippet, ddclient will use the contents of
DD_LOGIN as the login value and the contents of DD_PASSWORD as the
password value.
These can in turn be supplied via the command line, .env files or any
other mechanism to safeguard sensitive information.
The password regex searches for password assignments, extracts the
password and replaces it with a dummy value to prevent it being logged.
This change adjusts the password regex to no longer accept trailing
characters behind the password string
Looks like there is a bug in line 542 in ddclient.in. The syntax of how the server URL is being set is different to all the other dynamic DNS services. To be precise there is one additional parameter. Instead of handing over the URL, the server variable receives the second "1" in the code below.
$globals{postscript} can now contain a full command string including
arguments. In order to facilitate this, the file executability check
(-x) has been modified such that the first substring up to the first
space (if it exists) is what is checked, rather than the whole string.
Example bodies I've seen:
```
0013
good 127.0.0.1
0
```
```
0013
nochg 127.0.0.1
0
```
```
007
nohost
0
```
Seems like the trailing zero was not there before as the code relied
on `pop`. Instead, we find the first line that matches `good`/`nochg`.
From doc in IO::Socket::IP in "IO::Socket::INET" INCOMPATIBILITES
section:
-----
The behaviour enabled by "MultiHomed" is in fact implemented by
"IO::Socket::IP" as it is required to correctly support searching for a
useable address from the results of the getaddrinfo(3) call. The
constructor will ignore the value of this argument, except if it is
defined but false. An exception is thrown in this case, because that
would request it disable the getaddrinfo(3) search behaviour in the
first place.
-----
Module IO::Socket::INET6 is deprecated.
There is common IO::Socket::IP module, which is working with ipv4 and
ipv6 in same way. There is backward compatibility with IO::Socket::INET6
