NAME
linkstat - log accessibility status of a destination
SYNOPSIS
linkstat [ {-s|-o logfile} ] [ OPTIONS ]
host
DESCRIPTION
The point of this utility is to log link outages. It will ping whoever
you want, however often you want; when they don't answer a few times in
a row, they're considered down; when they anser a few times in a row,
they are considered up. By default, linkstat logs to stdout, sends
probes every second, and changes state after 3 consecutive probes return
the opposite of the current status.
OPTIONS
- -h
-
Prints a help message and exits.
- -s
-
Tells linkstat to log to syslog(3).
- -o logfile
-
Tells linkstat to log to logfile.
- -t tos
-
Set TOS value used in outgoing pings (defaults to 0).
- -i time
-
Sets the time between pings, which is also how long we wait for a reply.
The value is in seconds, and accepts floating point values. The default
is 1, and linkstat won't accept a lower value unless you edit the
source and recompile (to prevent ping floods by means of a stupid
mistake).
- -n num
-
Sets the number of consecutive results needed for a state change
(defaults to 3).
- -f facility
-
If logging to syslog, the name of the facility to use (defaults to
user). Acceptable values can be found in syslog(3). This option
implies -s.
- -l level
-
If logging to syslog, the name of the log level to use (defaults to
warning). Acceptable values can be found in syslog(3).
