Library /sys$common/syshlp/ncphelp.hlb SET, EXECUTOR, ALIAS INCOMING option  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Specifies whether the local node is willing to accept incoming
 requests directed to the alias node identifier specified for  the
 local node.  The alias node identifier is described under the ALIAS
 NODE parameter.  There are two options for ALIAS INCOMING:

     ENABLED     Specifies that the local node will accept
                 incoming connect requests directed to the alias
                 node identifier.  This is the default if an
                 alias node identifier has been specified.

     DISABLED    Specifies that the local node will not
                 accept the incoming connect requests
                 directed to the alias node identifier.
