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 a nameserver line at the top to cause local
resolution:
nameserver 127.0.0.1resolvd also monitors the routing socket
for proposals learned by
dhcpleased(8), iked(8), slaacd(8), or network devices which natively learn DNS information
such as sppp(4) or umb(4). Proposals can be sent manually using the
route(8)
nameserver command. The 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.
