NAME¶
ptpd2.conf - Precision Time Protocol daemon config file
Settings in the PTPd configuration file are grouped into sections and take the
form of
section:key="value" variables. The configuration file
can either be formatted that way (preferred) or in .ini file style where a
series of
key="value" variables is grouped into sections
using
[section] headers. Every setting listed here can
also be specified as a command line parameter
(--section:key=value ). Quotation marks are optional.
NOTE: the configuration file must end with a newline.
RELOADING CONFIGURATION¶
Only a small number of configuration file settings (SNMP, lock file
configuration) requires PTPd restart to take effect. All other settings can be
changed while ptpd is running - configuration file is reloaded and checked for
changes when PTPd receives the SIGHUP signal. When reloading configuration,
PTPd will always attempt to test settings before applying them and once
running, will never exit as a result of configuration errors.
PRIORITY¶
Any setting passed as a command line parameter will always take priority over
the configuration file, so once ptpd is running, those settings cannot be
changed - a warning will be logged on every attempt to change those settings
using the configuration file.

BUGS¶
Configuration file support has only been introduced in version 2.3. There may
still be some inconsistencies in the way some settings are parsed and while
order should not make any difference, for some complex behaviours it may still
be the case. Please report any bugs using the bug tracker on the SourceForge
page:
