With respect to IPv6, the client is affected by the Connection Broker configuration as given in the following files:
Default configuration file (optional):
Global configuration file (optional):
User-specific configuration file (optional):
A configuration file explicitly specified by the
The common DTD for all these XML configuration files is:
You can see the contents of the DTD also in the Tectia Server for IBM z/OS User Manual.
All of the above-mentioned configuration files are optional; if none are provided, the defaults, as defined in the DTD, are used. Files later in the above list override settings in their predecessors, if any.
For the purposes of IPv6 support, the
address-family sub-element of the
default-settings element is the first consideration:
<!-- Both ipv4 and ipv6 are enabled by default --> <!ENTITY default-address-family-type "any"> <!-- address-family mode setting ipv4 & ipv6--> <!ELEMENT address-family EMPTY> <!ATTLIST address-family type (any|inet|inet6) "&default-address-family-type;">
These lines in the DTD mean that
address-family may be coded as
inet6 and that if not
specified, it defaults to
any. Note that the default on the client side is
the more permissive setting to support both IPv4 and IPv6, whereas the server defaults are
generally more conservative, supporting IPv4 only, in the absence of explicit
In many other places in the Connection Broker configuration, such as in tunnel definitions, IP
addresses or host names may be specified. Depending on the
chosen, IPv4 or IPv6 addresses are allowable.
