email should be sent via localhost, not the hostname

[Chris Jones]

ServletUtils.java seems to determine the host to connect to to send email with:

mailHost = InetAddress.getLocalHost().getHostName();

which (AFAIKS) returns the equivalent of /etc/hostname, which may not necessarily resolve to a 127.0.0.0/8 address. In doing so Eucalyptus may end up talking to the LAN/public IP of the machine for SMTP, which will result in relaying being denied in a default Ubuntu postfix install.

Is there any reaosn for not using "localhost"?

Chris,

I agree. I'm committing such a fix to the Ubuntu Eucalyptus package.

I'm also adding a task against Eucalyptus upstream, in case they know better. If so, please speak up. If not, please cherry pick r601 from lp:~ubuntu-core-dev/eucalyptus/ubuntu and apply upstream.

    information, LP: #424457
  * clc/modules/www/src/main/java/edu/ucsb/eucalyptus/admin/server/ServletUtils.java:
    if we're going to use the local host to send email, use 'localhost' as
    the hostname, rather than the externally resolvable hostname which
    breaks in the default ubuntu postfix configuration, LP: #412676
  * debian/control:
    - have eucalyptus-common depend on openssh-server and openssh-client,
      as these should really be installed on most any Eucalyptus system,
      LP: #411656
    - have eucalyptus-common recommend unzip, since Eucalyptus uses zip
      files for credentials, which may be needed on various systems,
      LP: #436876
    - recommend libpam that provides pam_motd, LP: #436199
    - conflict with apache2-mpm-itk, LP: #338344
  * debian/eucalyptus-common.postinst: configure VNET_DHCPDAEMON and
    VNET_DHCPUSER appropriately for default Ubuntu on initial install,
    LP: #364938

  [ Colin Watson ]
  * debian/control:
    - Make eucalyptus-nc explicitly depend on apache2-mpm-worker |
      apache2-mpm-prefork, since the NC requires that Apache be configured
      to only start a single child (LP: #338344).
