Adds a rule to a security group that allows traffic to pass.


euca-authorize  group_name [-P {tcp,udp} -p port_range] [-s cidr_range]
euca-authorize  group_name [-P icmp -t type:code] [-s cidr_range]


Option Description Required
group_name Name of the security group to add the rule to. Yes
--egress (VPC only) Manage an egress rule, which controls traffic leaving the group.

Default: If this option is not specified, the rule is an ingress rule (applies to traffic entering the group).

-P, --protocol protocol | protocol_number IP protocol name or number.

Valid values: tcp | udp | icmp -1/all

Note: You can specify arbitrary IANA-assigned protocol numbers as well as the special values "all" and "-1", which refer to all network traffic, in VPC security groups. As a convenience, if a protocol is specified by name euca-authorize and euca-revoke will consult /etc/protocols to discover its number.
-p port_range Specifies the range of ports to allow for TCP and UDP. Not valid for ICMP.

Valid values: Single integer or range (min-max). Use -1 to specify all ports.

-t, --icmp-type-code ICMP type and code specified as "type:code". Only works if you specify ICMP as the protocol. Conditional
-o, --source-group source_group (Non-VPC only) Group from which traffic is authorized by the rule. Every instance in the security group is allowed to pass traffic. No
-u, --source-group-user source_group_user ID of the security group user you name in the -o parameter No
-s, --source-subnet source_subnet Addresses to apply the rule to
