This feature is new in the Solaris Express 1/04 release.
Retransmission parameters and packet time-out parameters have been added to the /etc/inet/ike/config file. The parameters enable the administrator to tune the IKE Phase 1 (Main Mode) negotiation. The tuning enables Solaris IKE to interoperate with platforms that implement the IKE protocol differently. The parameters also help the administrator adjust for network interference and heavy network traffic.
For a detailed description of the parameters, see the ike.config(4) man page.
