Rationale:
* For consistency.
* It's generally not a good idea to mix interpolation with `sprintf`
because the interpolated string itself might coincidentally (or
maliciously) contain format specifiers.
This adds a protocol to email IP address changes without needing a
dynamic DNS service. This is useful if you don't use a DDNS service
but want to be notified when the IP of a machine changes.
Rationale:
* Logging to STDERR enables separation of processable output (e.g.,
`--version` or `--help`) and ephemeral status/error messages.
* A single file descriptor for all log messages makes it easier for
users to capture all log messages.
* Consistency: it's what most utilities do.
`$config{$h}{'status'}` was always initialized to a non-`undef` value,
so the `//` fallbacks never did anything. Instead, any protocol that
does not explicitly update the legacy `status` variable (such as
`godaddy`) would always appear to have failed even if it had
succeeded.
Change the `status*` variables to `undef` by default, and only set
them when an attempt is made so that the legacy `//` fallback works as
expected.
This shouldn't matter in practice because the `status-ipv$ipversion`
field is initialized to a non-`good` value so failing to set it to
`bad` doesn't turn it `good`, but it improves readability.
The `dnsexit2` protocol reads the IP addresses from the new `ipv4` and
`ipv6` variables, so it should update the `status-ipv4` and
`status-ipv6` variables.
Perl version strings are flawed in a few ways. Convert them to
user-friendly strings when printed so that Git tags and tarball names
are easier for downstream distributions to work with.
Passing `--version=short` simply prints the version and exits. This
will make it possible for a future commit to change `configure.ac` to
extract the version string from `ddclient.in` to avoid maintaining the
same version string in two places.
This prevents the `%builtinweb` or `%builtinfw` skip defaults from
overriding a user's explicitly empty `--web-skip=` or `--fw-skip=`
setting.
This is technically a backwards-incompatible change: Any config that
explicitly sets `--web-skip` or `--fw-skip` to the empty string but
depends on the built-in skip behavior will fail. This is unlikely to
affect many (if any) users; compatibility concerns are believed to be
far less significant than the potential need to turn off the built-in
skip.
`--arg` is preferred over `-arg` because the broader convention is to
use double hyphens for long option names. Perl accepts either.
`--arg` is preferred over `arg` to avoid confusion between `--use=ip`
and `--ip` and similar option pairs.
The `ciscov4`, `ciscov6`, `cisco-asav4`, and `cisco-asav6` strategies
were never implemented, and it doesn't make sense to implement them
because the `v4` and `v6` variants don't follow the pattern
established by the `%builtinfw` strategies.
The `%builtinfw` strategies were never implemented for `--usev6`.
Porkbun API requires separation of the root domain and subdomains.
Previously ddclient only supported one layer of subdomain or the root domain
by selecting between the two with the boolean 'on-root-domain'.
This change now allows to specify the root domain via the 'root-domain' parameter
ddclient will then split the host domain into root and subdomain

The mythicdyn module is modified so that it will update either or both V4 and/or V6 addresses depending upon which specific address parameters have been defined in the config file. The module examines the wantipv4 and wantipv6 parameters.
If required, both addresses will be updated in a single invocation.
The cloudflare documentation example had lines with a comment after a
backslash. This actually did not work in the parser until now.
The lines in question:
#protocol=cloudflare, \
#zone=domain.tld, \
#ttl=1, \
#login=your-login-email, \ # Only needed if you are using your global API key. If you are using an API token, set it to "token" (without double quotes).
#password=APIKey \ # This is either your global API key, or an API token. If you are using an API token, it must have the permissions "Zone - DNS - Edit" and "Zone - Zone - Read". The Zone resources must be "Include - All zones".
#domain.tld,my.domain.tld
Adjust `nic_nsupdate_update` to use `wantipv4` and `wantipv6` and
support simultaneous IPv4 and IPv6 updates.
Also, set proper `status-ipv4` and `status-ipv6` values after successful
update.
Adjust `nic_noip_update` to use `wantipv4` and `wantipv6` and support
simultaneous IPv4 and IPv6 updates.
Note: Unlike `nic_dyndns2_update`, `$returnedips` actually contains
valid IPv4 and IPv6 addresses, so we can use the response to update the
status.
When the configuration used the legacy 'use' parameter, we already
populated the new internal 'wantipv*' field alongside the legacy
'wantip' field. This allows both old and new providers to work.
The legacy providers set 'status'/'ip'.
The new providers then set 'status-ipv*'/'ipv*'.
The caching logic would look for 'status' and 'ip' when encountering a
'use' parameter in the config. We previously already changed ddclient to
set 'status' when 'status-ipv*' was set. Now we also set 'ip' from
'ipv*'. This ensures caching correctly works.
This reverts the changes from 36744e5. This will be reimplemented once
the build process is better documented and properly implemented
by any downstream not yet using it (as of now linuxserver.io).
See https://github.com/linuxserver/docker-ddclient/issues/77
- Support wantipv4 and wantipv6 configs automatically
- Remove manual record type setting
- Add support for hosts on your zone (subdomain)
- Update config examples
- Code/logic improvements
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
