And now for something completely diffrent :-)

Hello chaps

Ever thougt of creating contrib directory that would come with DHCP server
like contrib folder under doc/ which could contributed scripts,examples 
howto´s etc etc..
We could point users on the directory and Ralph and Ted could include 
contributed examples, setups,
 scripts perhaps in next edition of DHCP Handbook.

Got more up my sleeve if needed

Best regards
               Johann B.

Sample one

#!/bin/bash
#
# Script that runs syntax check against is DHCP file
# If correct then backs up the current file and copys the file
# in question over the current one and restarts the DHCP server...


#file="file.new"                               # The file you will be 
changing/editing
#file2="file"                                     # The running file 
           
#dt="/path/to/dhcpd -t -cf "              # Change syntax to where ever 
dhcpd is

# On RHEL 4 check against single file

file="/etc/dhcpd.conf.new"
file2="/etc/dhcpd.conf"
dt="/usr/sbin/dhcpd -t -cf $file"

if $dt; then
          echo "Syntax OK"
          cp $file2  $file2.bak
          cp $file $file2
          service dhcpd restart      # For other OS than Redhat you need 
to HUP the daemon or stop and start it
       else
        echo "Syntax not Ok!!! check $file"
        exit 192
fi

exit 0

Sample 2

#!/bin/bash
#
# Script that runs syntax check against is DHCP file
# If correct then backs up the current file and copys the file
# in question over the current one and restarts the DHCP server...
# this script is useful where there is some automated process that
# changes the file in question  for  example some  web  interface 
# which is used to register the mac addresses...
#
# diffrence from sample one it will run the script silently, if it fails
# stop running and mail the dhcp admin...

#file="file.new"                               # The file you will be 
changing/editing
#file2="file"                                     # The running file 
           
#dt="/path/to/dhcpd -t -cf "              # Change syntax to where ever 
dhcpd is
#da="dhcpadmin at example.com     # Mail address of who's responsible of 
running the DHCP server

# On RHEL 4 Silent check against single file, mail on error

file="/etc/dhcpd.conf.new"
file2="/etc/dhcpd.conf"
dt="/usr/sbin/dhcpd -t -cf $file"
da="dhcpadmin at example.com"

if $dt &> /dev/null ; then
          cp $file2  $file2.bak
          cp $file $file2
          service dhcpd restart      # For other OS than Redhat you need 
to HUP the daemon or stop and start it
       else
        echo "Syntax not Ok!!! check $file" | mail -s "From DHCP 
Server:  Arg!! wrong syntax in file" $da
        exit 192
fi

exit 0
