dhclient-exit-hooks

[fbsd]

I do not see why postfix would have any thing to do with logger not
working.

I added some ehco statments to test if the "if" statment is working.
In this pass /etc/dhcpd.name-servers.tmp = /etc/dhcpd.name-servers
so the second echo should not have been executed, but it was

>From testing it looks like only the dhcpc variables plus mv,
and echo commands work in the script.

from the boot log
dc0: link state changed to DOWN
dc0: no link ....dc0: link state changed to UP
 got link
dc0: link state changed to DOWN
 before if check
 after if check
DHCPREQUEST on dc0 to 255.255.255.255 port 67
dc0: link state changed to UP
DHCPACK from 10.0.10.2
dc0: link state changed to DOWN
bound to 10.0.10.4 -- renewal in 43200 seconds.


and here is the dhclient-exit-hooks script

#!/bin/sh

# PROVIDE: dhclient-exit-hooks
# REQUIRE: SERVERS

###############  Start of refresh dhcpd dns ip  ####################
# This script will propagate to dhcpd the changed dns servers ip
address
# which dhcp-client puts in resolv.conf.
#
# In dhcpd.conf replace the "option domain-name-servers" line with
this
#
#  include "/etc/dhcpd.name-servers";
#
# Spript uses the dhcpc variables to build temp line in dhcpd
format.
# Then compare temp content to production content.
# If different replace production content with new content from
temp,
# and restart dhcp to reread dhcpd.conf containing new ISP dns ip
addresses.
#
# logging event and sending email to user root is optional.
#
# Note: All LAN machines using dhcpd will not get new ISP dns ip
addresses
# until they reboot or their lease comes up for renewal.

# Each of the following lines must be one long line. IE: no wrap
arounds

But it's not dhclient that's emitting the error, is it?  It's your
MTA.
(check in /etc/mail/mailer.conf, and you will see that send-mail is
an alias for the binary of your MTA)

Atom's suggestion is worth pursuing.
