SYNOPSIS¶
arpsnmp [
-d ]
[
-f datafile ]
[
-s sendmail_path ]
[
-m addr ]
file [
... ]
DESCRIPTION¶
Arpsnmp keeps track for ethernet/ip address pairings. It syslogs activity
and reports certain changes via email.
Arpsnmp reads information from a
file (usually generated by
snmpwalk(8)).
The
-d flag is used enable debugging. This also inhibits mailing the
reports. Instead, they are sent to
stderr.
The
-f flag is used to set the ethernet/ip address database filename. The
default is
arp.dat.
(Debian) The
-s flag is used to specify the path to the sendmail program.
Any program that takes the option -odi and then text from stdin can be
substituted. This is useful for redirecting reports to log files instead of
mail.
(Debian) The
-m option is used to specify the e-mail address to which
reports will be sent. By default, reports are sent to
root on the local
machine.
Note that an empty
arp.dat file must be created before the first time you
run
arpsnmp.
