Description (partial)

IPS Sig auto-updates may fail with the following diagnostics:

Auto Update Statistics
   lastDirectoryReadAttempt = 11:59:55 UTC Mon Apr 14 2014
    =   Read directory:
    =   Error: AutoUpdate exception: openConnection: Caught IpAddrException badAddrString.  Unable to use the DNS settings for AutoUpdate.Verify DNS server IP or IP in cisco-url (if configured) and try again.

This can happen in IPS software 7.2 and later, which uses URL in auto-update configuration. The issue is caused by nscd Linux daemon not running on the IPS.
