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
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`.
This is no longer used since commit 6c951a0395 ("Add files via
upload"), which updated to the Cloudflare API v4. The new API does not
require any preprocessing of the domain name.
This will make it possible for the Debian package to fetch the list of
supported firewall/router devices and prompt the user to choose one
upon installation.
This will make it possible for the Debian package to fetch the list of
supported built-in web-based IP discovery services and prompt the user
to choose one upon installation.
The new code will always warn if ddclient.conf is accessible by others,
warn if it is owned by ddclient and accessible by the group,
and otherwise warn if it is writable but not owned by ddclient.
This primarily allows two permission modes for ddclient.conf:
First, the classic `ddclient:ddclient mode 0600` as well as the
more restrictive `root:ddclient mode 0640` which previously
warned unnecessarily.
Cloudflare was returning values not being matched properly by the regex expression.
Numbers that were not Headers.
This fix or patch should resolve that issue, by only collecting one match to JSON relevant data.
