Sun Java System Messaging Server 6.3 64-bit Installation Technical Note

ProcedureTo Ensure DNS is Running and Configured Properly

  1. Make sure that the /etc/resolv.conf file has name server entries with the IP addresses of valid name servers. For example:

  2. Make sure that the /etc/hosts file has an entry for the fully qualified host name of the server. This fully qualified host name should be listed before the non fully qualified host name. For example: wireless loghost
  3. Make sure that the /etc/nsswitch.conf file is configured to use files first to resolve host names. The hosts line in the nsswitch.conf file should list files first in its entry:

    hosts: files dns nis [NOTFOUND=return]

    Or, if NIS is not used:

    hosts: files dns
  4. On Solaris 10 platforms, you not only have to add the Fully Qualified Domain Name (FQDN) to the /etc/hosts file, but also to the /etc/inet/ipnodes file.

    Otherwise, you'll get an error indicating that your host name is not a fully qualified domain name (FQDN).
