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.

Script Syntax:

./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 164.99.100.134

Prerequisites:

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.

1. Login to DNS/DHCP  management console
2. Select forward/reverse zone > control tab
3. Select “allow-update any” option
4. restart rcnovell-named service.

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 164.99.100.101 636 cn=admin,o=novell 1 1 cn=DNS-DHCP,ou=DNSDHCP,o=novell
