Unix TCP Equivalent Settings in Windows 2000?

Posted by Cliff on from the RWIN-SWIN-and-MTU dept.

sameerdesai asks: "While working on a project that required client-server functionality I was running into processes that wouldn't finish and eventually hang. While running packet tracing, I found out the tcp_fin_wait_2_timeout setting on the server side (UNIX) was too low for the Windows client, and after increasing that value it worked great. I am trying to apply a similar technique for a Windows server and was wondering what the equivalent registry key is for UNIX's tcp_fin_wait_2_timeout setting? Also, is there a guide out there that compares TCP setting in UNIX with Windows?"

    Is HKLM\System\CurrentControlSet\Services\Tcpip\Param eters
    REG_DWORD
    30

    Setting this to anything below 30 decimal will just set it to 30 anyway though.

      Looks like you forgot to mention one thing, and the slashed up URL made it slightly more difficult to discover.

      There are about a hundred different entries contained in HKLM\System\CurrentControlSet\Services\Tcpip\Param eters. The REG_DWORD in question is the one labeled "TcpTimedWaitDelay". Accepted values are between 30 and 300 (seconds).

    REGEDIT [/v|-v] [/s|-s] <FILENAME>

    [/s|-s]
    When a filename is specified on the command line, this switch is used to suppress any informational dialog boxes that would normally be displayed. This is useful when the Setup program for an application wants to execute REGEDIT.EXE with a .REG file, but does not want the user to be confused by any dialog boxes that are displayed.

    Put what you need in the file you wish to import.

    "REGEDIT " isn't the obscure part. Just IMHO everything about the bits and handles after that is about equally obscure between regedit and /proc. Both are equally unfriendly. But you can do /proc without a special GUID program, so also IMHO it wins the toss.
