Logical hostname

From Zimbra :: Wiki

Jump to: navigation, search
Every Zimbra host has a logical hostname under which that host's configuration data is stored in LDAP.  

The logical hostname need not be related to the name returned by the hostname command, nor need it be the name returned from a reverse lookup of the host's IP address.

The logical hostname need not be related to the domains hosted.

The logical hostname is selected at install time, and is configured in the LDAP server at that time.

The logical hostname can be determined by running the zmhostname command.

Changing the logical hostname is a pain.

The following requirements for the logical hostname should be met:

  • The logical hostname should resolve in DNS from the other hosts in the system.
  • The logical hostname should resolve in DNS from itself.
  • If the logical hostname resolves to an IP address not configured on the host, then certain port forwarding should be configured. (See NAT and DNS)
