- Firstly, take backup of original DHCP configuration file and store in local machine through WinScp.
Path :
root/etc/dhcpd.conf
- To unlock original dhcp file we need to run following commands in EXPERT mode:
Expert@Hostname# lsattr
/etc/dhcpd.conf
# chattr -i
/etc/dhcpd.conf
# lsattr
/etc/dhcpd.conf
- To configure file enter into VI edit mode,
Expert@Hostname#vi
/etc/dhcpd.conf
Add following syntex after curly bracket,
host Encrust-PC { ######
hardware ethernet
00:0c:29:08:60:15; ######
Changes we made in this steps.
fixed-address
20.20.20.18; ######
}
Save configuration by
shift++ command.
- Now, previously we unlock dhcpd.conf file again after made changes in that we need to lock so Checkpoint can boot from that file.
Steps
to lock file again:
Expert@Hostname# lsattr
/etc/dhcpd.conf
# chattr +i
/etc/dhcpd.conf
# lsattr
/etc/dhcpd.conf
- Create Rule such as destination will be broadcast and port 67 & 68 should be allowed.
