    DHCP/DNS Update issue

    Hi,

    We currently have issue with the Novell DHCP updating the external DNS (Redhat)

    Only half the computers get registered... strange...

    Here's what we can see in the /var/log/message related to DHCP updating the dns

    What we see when there is no update made to the DNS by the DHCP:

    Nov 26 08:36:02 SERVER01 dhcpd: DHCPREQUEST for 10.148.56.181 from 00:22:4d:82:14:fd (COMPUTERXX) via eth0
    Nov 26 08:36:02 SERVER01 dhcpd: DHCPACK on 10.148.56.181 to 00:22:4d:82:14:fd (COMPUTERXX) via eth0
    Nov 26 08:36:27 SERVER01 dhcpd: DHCPDISCOVER from 00:22:4d:82:14:fd (COMPUTERXX) via eth0
    Nov 26 08:36:27 SERVER01 dhcpd: DHCPOFFER on 10.148.56.181 to 00:22:4d:82:14:fd (COMPUTERXX) via eth0
    Nov 26 08:36:27 SERVER01 dhcpd: DHCPREQUEST for 10.148.56.181 (10.148.56.2) from 00:22:4d:82:14:fd (COMPUTERXX) via eth0
    Nov 26 08:36:27 SERVER01 dhcpd: DHCPACK on 10.148.56.181 to 00:22:4d:82:14:fd (COMPUTERXX) via eth0

    What we see when there is an update made to the DNS by the DHCP:

    Nov 26 08:12:27 SERVER01 dhcpd: DHCPDISCOVER from 00:19:d1:a9:95:5f (COMPUTERXX) via eth0
    Nov 26 08:12:27 SERVER01 dhcpd: DHCPOFFER on 10.148.56.143 to 00:19:d1:a9:95:5f (COMPUTERXX) via eth0
    Nov 26 08:12:27 SERVER01 dhcpd: Added new forward map from COMPUTERXX.domain.com to 10.148.56.143
    Nov 26 08:12:27 SERVER01 dhcpd: unable to add reverse map from 143.56.148.10.in-addr.arpa. to COMPUTERXX.domain.com: timed out
    Nov 26 08:12:27 SERVER01 dhcpd: DHCPREQUEST for 10.148.56.143 (10.148.56.2) from 00:19:d1:a9:95:5f (COMPUTERXX) via eth0
    Nov 26 08:12:27 SERVER01 dhcpd: DHCPACK on 10.148.56.143 to 00:19:d1:a9:95:5f (COMPUTERXX) via eth0
    Nov 26 08:12:38 SERVER01 dhcpd: DHCPINFORM from 10.148.56.143 via eth0
    Nov 26 08:12:38 SERVER01 dhcpd: DHCPACK to 10.148.56.143 (00:19:d1:a9:95:5f) via eth0

    - Note that there is an unable to add reverse map error ( We don't want to allow reserve map... Is there any way to force the DHCP not to update the reverse map ) ??? Our DHCP config is managed thru imanager.

    If we look in the var/log/messages from the redhat DNS, we don't see any error related to problem with registering new binds.

    We have 25 servers in 25 different sites and all of them have the same problem... only few of the pcs gets registered....


    Any ideas ?
