Patrick,
I just finished the netreg installation. I reveived the following when
trying to start the DHCP service:
Env: /etc/init.d/dhcpd
I have all the files in the exact location. What do you think happen?
Any help will be greatly appreciated.
Thanks,
Jsoe

Calissa,
You need to start /usr/sbin/dhcpd with the "-cf" to be able to specify a
different path for the dhcpd.conf file. The default is /etc. Example:
/usr/sbin/dhcpd -cf /etc/dhcpd/dhcpd.conf -lf
/var/state/dhcp/dhcpd.leases
You should create a startup script for dhcpd and place it in your
/etc/rc.d/init.d directory, then create symlinks to the start script in
each
runlevel directory (rc0.d,rc1.d,rc2.d,rc3.d,rc4.d,rc5.d,rc6.d). See the
NetReg-HowTo guide on how to create symlinks (Chapter 5.3). Attached is
a
startup script for dhcpd on a Red Hat 9.0 Linux system. It will work as
long
as the following are true:
1. dhcpd.conf is in /etc/dhcpd
2. dhcpd.leases is in /var/state/dhcp/dhcpd.leases
If any of these files are in different locations then your will need to
edit
this script and change the following lines:
# Check that ISC DHCPD files exist
[ -f /usr/sbin/dhcpd ] || exit 0
[ -f /etc/dhcpd/dhcpd.conf ] || exit 0
[ -f /var/state/dhcp/dhcpd.leases ] || exit 0
OPTIONS="-cf /etc/dhcpd/dhcpd.conf -lf /var/state/dhcp/dhcpd.leases"

Patrick,
The fix below worked for me as well :) the files are refreshing every
minute
like they are supposed to :) thank you once again for your help... you
really are awesome!!
netreg is running great for me, except when i try to start dhcpd it
wants to
read the conf file from /etc/dhcpd.conf instead of
/etc/dhcpd/dhcpd.conf, if
i manually make a copy of the /etc/dhcpd/dhcpd.conf file in the /etc
directory everything is wonderful, but i shouldn't have to do this...
the
path in variables.pl is correct it states:
$DHCPDCONFPATH = "/etc/dhcpd";
$DHCPDCONFFILE = "dhcpd.conf';
File permissions may be an issue... is there somewhere else i need to
change
the path?
is there something that i am missing?
Thanks again for all of your help!
Calissa
