NAME
resolvd —
a daemon to handle nameserver
configuration
SYNOPSIS
resolvd |
[-dv] |
DESCRIPTION
resolvd handles the contents of
/etc/resolv.conf, which contains details of the
system's DNS nameservers, and is read by the resolver routines in the C
library. Nameservers are learned from various sources, incorporated in a
priority order, then user-edited information found in the pre-existing file is
re-appended.
resolvd checks whether
unwind(8)
is running, and if so places
nameserver 127.0.0.1at the top, to cause local resolution.
resolvd also monitors the routing socket
for proposals learned by
dhclient(8),
dhcpleased(8), slaacd(8), or network devices which natively learn DNS
information such as umb(4). Proposals can also be sent using the
route(8)
nameserver command.
These proposals are added in priority order, but commented out if unwind(8) is running.
After that, resolvd appends all
user-edited lines found in the file.
resolvd also notices if the
/etc/resolv.conf file is edited, and will rewrite
the file, re-blending the various pieces of information. It will also create
/etc/resolv.conf if it does not exist or if it is
empty.
The options are as follows:
-d- Do not daemonize. If this option is specified,
resolvdwill run in the foreground and log to stderr. -v- Produce more verbose output.
