New Features

Eucalyptus 4.1.2 introduces the following new feature.

Feature Description
Adds the ability to pass SCTP traffic between instances. This feature enables SCTP traffic passing between instances when using EDGE network mode.
  1. SCTP requires the conn track modules to be installed on each NC running in EDGE mode:

    modprobe nf_conntrack_proto_sctp

  2. Check the underlying network to verify it is configured and capable of passing new types of IP traffic. Perform the test outside the Eucalyptus cloud.
  3. Modify the cloud.network.ec2_classic_additional_protocols_allowed property:

    euca-modify-property –p cloud.network.ec2_classic_additional_protocols_allowed =132

  4. Set the euca-authorize option to --protocol 132 (the IANA-assigned protocol number for SCTP) to enable SCTP for a security group:

    euca-authorize mygroup --protocol 132

  • If you need to remove the rule from a security group, use euca-revoke.
  • If you want to remove the protocol from the cloud property, all the related security group rules should be revoked first.
  • All ports are available to SCTP. (Port ranges are ignored.)
