This KB refers to IPAM 4.1 and higher, which supports ISC DHCP management and monitoring
The following ISC DHCP minimum requirements and configurations are needed for IPAM to access your ISC servers.

-Supported base version for ISC   =  isc-dhcp-4.2.4-P1
-For more information reference:  https://kb.isc.org/article/AA-00736

 

 


»Supported Operating System:

 

-POSIX compliant Linux distributions
 
»User access:
-User account needs to be configured to allow remote telnet or SSH access to ISC DHCP machine
-Read and write file access for user on the configuration files.

»Cli commands:
dhcpd --version
grep
echo $PATH_DHCPD_DB
dhcpd -t -cf 
ps -w -A -o comm,pid,args | grep ^dhcpd –w (or) ps -A -o comm,pid,args | grep ^dhcp  (or)  ps -x -o comm,pid,args | grep ^dhcp
[ -f "" ] && echo 'true'
uname -mrs
sha1sum  (or) sha1 (or)  digest -v -a sha1
[ -r "" ] && echo 'true'
[ -w "" ] && echo 'true'
cat
\cp -u -f -b -S.backup -p "" ""
\rm -r -f ""<
mkdir
Note:

IPAM will need to seek the config file in one of the following paths below:


»Configuration File:
"/etc/dhcpd.conf"
"/etc/inet/dhcpd4.conf"
"/etc/dhcp/dhcpd.conf"
"/usr/local/etc/dhcpd.conf"

»Lease File:
"/var/db/dhcpd.leases”
"/var/lib/dhcpd/dhcpd.leases"
"/var/lib/dhcp/dhcpd.leases"
"/var/db/dhcpd/dhcpd.leases"

»Script File:
"/etc/init.d/dhcpd"
"/etc/init.d/dhcp"
"/etc/rc.d/dhcpd "
"/etc/init.d/isc-dhcp-server"
"/usr/local/etc/rc.d/isc-dhcpd“

 
Configuring your ISC DHCP Server:

On the fresh Installation of ISC DHCP from a terminal prompt, enter the following command to install dhcpd: sudo apt-get install isc-dhcp-server  

To change the default configuration by editing /etc/dhcp3/dhcpd.conf to suit your needs and particular configuration.   

You may also want to edit /etc/default/isc-dhcp-server to specify the interfaces dhcpd should listen to.

By default it listens to eth0  

Next, you would need to assign a static ip to the interface that you will use for dhcp.

Note: Ensure the ISC service is running so IPAM can communicate with your ISC DHCP server. After editing the configuration file, restart the service.
