Setting a Hostname

JetPatch Agent Manager needs to access its host server by hostname. To enable this:

1. Configure a server hostname:
   1. Log into the server, and open the following file for editing:

      /etc/sysconfig/network

   2. Set the HOSTNAME to the new hostname. For example:

      HOSTNAME="intigua.example.com"

      Save the file.

   3. Run:

      hostname <hostname>

      where <hostname> is the new hostname. For example:

      hostname intigua.example.com

2. Make sure the hostname is accessible by local applications:
   1. Run:

      hostname -f

      If the correct hostname is returned, it is available to applications and you're done with this. Otherwise:

   2. Check if nss-myhostname is installed. If not, run:

      yum install nss-myhostname

      and wait for installation to complete.

   3. Open the following file for editing:

      /etc/nsswitch.conf

   4. Find the line beginning with hosts, and add the new hostname to the end of the line. For example, change

      hosts: files mdns4_minimal dns

      to

      hosts: files mdns4_minimal dns intigua.example.com

   5. Again run hostname -f to confirm that the hostname is successfully resolved.
