    Hello, I have problem with boot tftp. I've tried to config my Cisco801 to
    boot from TFTP server, which is actually my winxp notebook with the
    SolarWinds TFTP server
    installed. When the router try get file from tftp server, it failed with
    error message of buffer overflow as follow:

    boot# list
    Status Size Dev Name
    ------ 48K flash TinyROM-1.4(1)
    8128K free 8192K total
    boot# boot tftp
    Accessing tftp://192.168.0.5/c800-y6-mw.121-9.bin
    TFTP initiated.

    File name: c800-y6-mw

    RAM size: 0x0066e394 (6742932)

    Raw size: 0x0054e880 (5564544)

    Image size: 0x002d162c (2954796)

    |----------------+----------------+----------------+----------------|

    Error 7 at offset 24.
    boot tftp: failed (1 second), "buffer overflow"
    boot: failed, "buffer overflow"
    boot#

    Info from tftp server:

    2005-04-02 21:00 :Sending c800-y6-mw.121-9.bin to (192.168.0.1)
    2005-04-02 21:00 :Timeout error sending c800-y6-mw.121-9.bin from
    (192.168.0.1), 512 bytes

    Questions:

    Why will it happen ( I've tried to use another tftp servers - didn't help)?
    How can I config my router 801 ?

    Thanks

  2. With MS-Win, nothing can amaze me anymore.

    Ever tried with something else like an OS?
