After migrating to OES DHCP server, you must delete the forward (A) and its PTR records which are created by NetWare DHCP server before a DDNS update is done. The following script deletes the forward (A) and its corresponding PTR records by reading the migrated DHCP lease db file.
./dhcp_oes.sh -l <lease_file> -s <dns_server>
Note: Using the -l option, you must specify the lease file of the DHCP server that is migrated to Linux
The example of command line execution of the script is:
./dhcp_oes.sh -l ./dhcpd.leases -s 220.127.116.11
Before executing this script, you must ensure that the following prerequisites are met:
a) requires Migrated DHCP lease DB file
b) In DNS server side, "allow-update any" should be enabled in forward & reverse zones.
Important: After executing this script, you must delete empty objects from the eDirectory. To do this, you must execute the following command:
dns-maint -d <LDAP host name> <LDAP port number> <Admin DN> <Secure LDAP or Not (0 -> non-SSL, 1->SSL)> <Read from Locator (0->No, 1->Yes)> <Locator FDN>
Example execution of the command is:
dns-maint -d 18.104.22.168 636 cn=admin,o=novell 1 1 cn=DNS-DHCP,ou=DNSDHCP,o=novell
