Installing the PTF

Apply the PTF to 3DNS System version 1.0.4 using the following process:

  1. Click here and follow the instructions for using the F5 Networks FTP site.

  2. Download 3dns104PTF-01.tar.gz file to the /var/tmp/ directory on the target 3DNS System.

  3. Enter the following commands on the command line:

    ndc stop
    kill `cat /var/run/big3d.pid`
    kill `cat /var/run/syslog.pid`
    ps -aux thttpd
    kill pid#
    cd /
    gtar xvzpUf /var/tmp/3dns104PTF-01.tar.gz

  4. Reinstall the big3d utility by selecting Install and Start big3d from the 3DNS Maintenance menu.

  5. Restart the syslogd utility.

  6. Restart the thttpd web server by selecting Start 3DNS Administration from the 3DNS Maintenance menu.

  7. Enter the following on the command line to complete the PTF installation:

    ndc restart

Note:  It is very important that you start big3d on all BIG/ip controllers, and then restart named on all 3DNS Systems.


What's fixed in this PTF

  This PTF resolves the following issues:

  • Fix 1863:  MX queries are corrupted when domain names and zone names are identical
    If you used zone names and domain names that were identical, the 3DNS System would return corrupted records. This issue is resolved, and the following example /etc/wideip.conf configuration now works properly. 

      wideip {
      address 192.168.111.111

       name "www.domain.com"
       alias "domain.com"
      pool {
         type "VSb"
         lbmode rr
         address 192.168.111.111
        }
       }

    The corresponding excerpt from /var/namedb/db.domain.com would read:

    domain.com. IN MX 10 mx.domain.com
    www.domain.com. IN A 192.168.111.111

  • Fix 2247:  The big3d parent process occasionally stops working
    The big3d's parent process occasionally stops working on the BIG/ip Controller when issuing virtual server status commands on behalf of the 3DNS Controller.  Because the 3DNS controller communicates with the BIG/ip Controller using the parent process of big3d, iQuery communication would be stopped. This problem was caused by a race condition between big3d and bigpipe for a system resource.  In the updated software, the race condition is now properly detected, error messages are logged, and queries are resubmitted.
