How to Discover DNS Zone by nslookup

This task includes the following steps:

1. Prerequisite - Set up protocol credentials

   This discovery uses the following protocols:

   • SSH protocol

   • NTCMD protocol

   • Telnet protocol

   For credential information, see Supported Protocols.

2. Prerequisite - Protocol parameters

   • If some commands are configured to run with sudo on the target host, in the Protocol Parameters dialog box, fill in the following fields:

     • Sudo paths. Enter the full path to the sudo executable, together with the name of the executable. You can add more than one entry if executable files are placed in various places on the target operating systems.

       Example: sudo,/usr/bin/sudo,/bin/sudo

     • Command List. Enter a list of the commands that are prefixed with the sudo.

       Example: lspath,ifconfig

   • Before activating discovery, confirm that the discovery user has all the required permissions to run the following command:

     cat <path to named config file and its include files>

     For details, see "Protocol Parameter Dialog Box" in the Data Flow Management section of the UCMDB Help.

3. Run the discovery

   1. Run the Range IPs by ICMP job.

   2. Run the Host Connection by Shell job.

   3. Run the Host Applications by Shell job.

   4. Run the DNS Zone by nslookup job.

      For details on running jobs, refer to "Module/Job-Based Discovery" in the Data Flow Management section of the UCMDB Help.
