.SH "NAME"
petrified \- bash client to update dynamic DNS at freedns.afraid.org
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Usage: \fBpetrified\fR [ \fB\-c\fR \fIconfig\fR ]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBpetrified\fR is a bash client to update dynamic \s-1DNS\s0 hosted at
<https://freedns.afraid.org>; the software goals are for simplicity,
flexibility and configurability while using the minimal system tools
installed with most distributions.
.PP
If upgrading from \s-1API\s0 v1 to v2, a manual action is required on the
FreeDNS website to generate a new \s-1API\s0 key for each domain name. See
<https://freedns.afraid.org/dynamic/v2/> for more information.
.PP
By default, petrified will use the length of the \s-1API\s0 key to automatically
choose the APIv1 or APIv2 \s-1URL\s0; this can be overridden in the configuration
file to force a specific version, as the v1 key length is variable but the
v2 key length is fixed at 24 chars.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-c\fR \fIconfig\fR" 4
.IX Item "-c config"
Specify an exact config file to use, ignoring global and per-user configs.
.SH "CONFIGURATION"
.IX Header "CONFIGURATION"
See \fIpetrified.conf\fR for all available options and their usage.
.PP
Copy the default configuration file to \fI/etc/petrified.conf\fR for global
use, \fI~/.petrifiedrc\fR for user-level use, or another location as desired.
At a minimum the \f(CW\*(C`DDNS_KEY\*(C'\fR variable must be configured for basic usage;
all other variables are preconfigured for system level (root) usage.
.PP
If implementing at the user level, be sure and set the various file options
to locations that are writable by the user; the default config is fully
documented and should make sense.
.PP
To use a custom configuration file, the \f(CW\*(C`\-c config\*(C'\fR parameter is supported;
note that using this option will not read the global or local configuration
files and only use the variables from this custom file.
.SH "SYSTEMD"
.IX Header "SYSTEMD"
The provided systemd unit files are designed to use the native systemd timer
functionality in place of a cron daemon. The timer can be activated as the
system user which will use specifically the global \fI/etc/petrified.conf\fR
configuration, or as any given user which will use the \fI~/.petrifiedrc\fR
configuration.
.PP
.Vb 2
\& system: systemctl \-\-now enable petrified.timer
\& systemctl list\-timers petrified.timer
\&
\& user: systemctl \-\-user \-\-now enable petrified.timer
\& systemctl \-\-user list\-timers petrified.timer
.Ve
.PP
Multiple interfaces can be configured using the standard systemd semantics
of unit overrides, which might look like this:
.PP
.Vb 6
\& /etc/systemd/system/petrified\-iface1.service
\& \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
\& .include /usr/lib/systemd/system/petrified.service
\& [Service]
\& ExecStart=
\& ExecStart=/usr/bin/petrified \-c /etc/petrified\-iface1.conf
.Ve
.PP
The first \f(CW\*(C`ExecStart=\*(C'\fR is intentional, needed to negate the existing value
first before defining a new value (systemd design for ExecStart override).
.PP
A corresponding new timer is then created to call this unit as it may be
desireable to run different interfaces on different time schedules, which
might then look like this:
.PP
.Vb 6
\& /etc/systemd/system/petrified\-iface1.timer
\& \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
\& .include /usr/lib/systemd/system/petrified.timer
\& [Timer]
\& Unit=petrified\-iface1.service
\& OnCalendar=0/8:00:00
.Ve
.PP
This timer will now operate the new custom unit when it's enabled.
