A keep-alive of "1" ("send a keep alive packet every 1 minute") will make a TCP session appear to be "active" (not idle), and will prevent idle tcp session disconnects on any networking equipment between your client and your Terminal Server (F5 network load balancing devices, firewalls, routers, switches, etc). If required, unlock the phone options. Sun Solaris 9 Sun Solaris 10 The IP-in-IP packet processing implementation in the IPsec and IP stacks in the kernel in Sun Solaris 9 and 10, and OpenSolaris snv_01 though snv_85, allows local users to cause a denial of service (panic) via a self-encapsulated packet that lacks IPsec protection. 0L gas and did see a slight improvement but you can't expect to much from a programmer alone on a gas engine. • Hybird loss and latency based algorithm.
