What does the heading Cost = 0 (normal cost) mean?

SackOpts Selective Acknowledgements (RFC 2018). Selective acknowledgements allow TCP to recover from IP packet loss without resending packets that were already received by the receiver. Most useful when employed with TCP large windows.

does this change to any other number when changing settings?Seeing different posts all seem to show the same Cost = 0 (normal cost).

Mine is set to 1

SG Recommends:

SackOpts="1" (string var, recommended setting is 1. Possible settings are 0 - No Sack options or 1 - Sack Option enabled) Selective Acknowledgements, as documented in RFC 2018

ok mine is the same but my TOS is set as a string value.If I set it as a dword value it shows nothing under IP type of service field (RFC1349)= Yet it is recommended to use the dword value.is this correct?

Ahhhhhhh thks Lobo that hit the nail on zee head, man thks for the wakeup call.I was trying to figure out and not thinking that the dword value would apply to win 2000,XP and not win 98se. More experimenting rite?

Are you setting it manually or using Cablenut?

Lobo · Post by **Lobo** » Tue Jul 16, 2002 11:00 am

Of cousre but backup registry in 98SE first

jujet84 · Post by **jujet84** » Tue Jul 16, 2002 11:16 am

Always backup lobo learnt that the hard way hahah.

mnosteele52 yes i have cablenut installed but I do install manually always have.
Like the hands on approach.
I use REGEditX to enter manualy, which when entering any info in the registry or changing this reg program takes me rite back to my last entrie.I realy like this proggie.
