VMS Help TCPTRACE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Starts the TCPTRACE utility.

    Format

      TCPTRACE  host [/BUFFERS=n | /FULL | /OUTPUT |/PACKETS=n |

                /PORT=option | /PROTOCOL=option]

1 - Parameters

 host

    Required.

    Remote host to which you are sending packets for tracing.

2 - Qualifiers

 2.1 - /BUFFERS

       /BUFFERS=n

    Optional. Default: 100.

    Number of buffers that TCPTRACE allocates for temporary storage.
    These buffers must be locked into the process working set, so
    you may have to decrease the number to accomodate the working
    set size or increase the number to prevent TCPTRACE from dropping
    packets.

 2.2 - /FULL

    Optional. Default: Brief display.

    Displays the packet contents.

 2.3 - /OUTPUT

    Optional. Default: Screen display.

    Redirects the trace output to a file. If you specify a file name
    that already exists, TCPTRACE appends new trace information to
    the existing file.

 2.4 - /PACKETS

       /PACKETS=n

    Optional. Default: 10.

    Stops the trace after TCPTRACE displays the specified number of
    packets.

 2.5 - /PORT

       /PORT ={LOCAL | REMOTE}= n

    Optional. Default: Trace all port numbers.

    Specifies the local or remote port number to trace. Use in
    conjunction with the /PROTOCOL qualifier to filter tracing to
    an exact port and protocol.

 2.6 - /PROTOCOL

       /PROTOCOL = {ARP | ICMP | IP | TCP | UDP}

    Optional. Default: IP

    Specifies the protocol to trace. Use in conjunction with the
    /PORT qualifier to filter tracing to an exact port and protocol.

3 - Examples

    1.$  TCPTRACE HOST1 /FULL /PORT=REMOTE=21

      Traces packets for host HOST1 and remote port number 21.
      TCPTRACE provides a full display of the packets contents.

    2.$  TCPTRACE HOST2 /FULL /PORT=(LOCAL=23, REMOTE=1056) -

      _$  /PACKETS=30 /OUTPUT=TELNET_TRACE.TXT)

      Traces packets for host HOST2 with a local port of 23 and
      remote port number of 1056. TCPTRACE provides a full display
      of the packets contents. TCPTRACE continues the trace for 30
      packets and writes the output to the file TELNET_TRACE.TXT in
      the current directory.
