    Ramon: You may want to think again, about using Yahoo Mail, to send
    email to this mailing list. Interesting what they add to your
    emails.... For those who cannot read Spanish, it says, more or less,
    "Everything about Love and Sex! The complete guide for the life of
    todays woman". Many of the people on the list use Gmail and Google
    does not add stuff like that to our emails. I am going to send you an
    invitation to get a Gmail account. Saludos desde Colombia, Lanny

    My point, as I'm sure you guessed or deduced, was that requests for
    help on this list should be at least a little more descriptive than a
    single FLA.

    And yes, I didn't know the answer, although I did understand the
    question. It's like the bottom posters, the "let's include the whole
    25 message thread" posters, and the "guess what _I_ want" posters, and
    also for those on the list who really don't know enough to understand
    minimalistic requests like this.

    (P.S.: 10Gb LAN, for those who don't know....)

    :-)

    yes, some 10gb cards are, yes there are people using them. I dont see
    what the issue is, are you conducting a random survey of some sorts ?

    I'll like to know from others their experience using 10 Gb LAN with CentOS 4 & 5.

    There is a chance here at work to change our backbone network to 10 Gb LAN if this get approved (by the CIO) i'll like to include to this project some 10 Gb Network Cards for our CentOS servers in order to connect them directly to the new backbone.

    Thank you in advance

    Hi, for the sake of the the CentOS email servers, would you
    please turn off attaching the additional copy of your email in
    HTML format?

    You are sending your email out in both plain text and HTML
    format, which more than doubles the size of your email, thereby
    doubling the amount of bandwidth the CentOS email server has
    to use to send it to the many many people on the list. This
    increases the cost of sending out your email by almost 100% but
    doesn't provide any more actual content.

    to see how to turn off HTML in many email clients look at
    this web page:
    http://expita.com/nomime.html#programs

    This is desired by the CentOS mailing list rules. per:

    1. Please turn off HTML in your e-mail client for these mailing
    lists. We have several subscribers who read the list with
    text only readers and they can't easily read HTML formatted
    e-mails. There is a place (somewhere) for the flowery stationary
    and themes that some mail clients offer ... but this is not
    it. Again, please only post text e-mails to these mailing lists.

    Quoted from:
    http://www.centos.org/modules/tinycontent/index.php?id
    (near the bottom)


    Thanks,
    Jeff Kinz

    and while we are at that: please use a decent mail program that can attach
    the correct MIME content-encoding header for your special characters.
    These are coming out as garbage because your message is us-ascii.

    Hi Kai
    Your email client doesn't understand "plain/text" ?

    Sorry, if that was not clear, I was referring (like you) to Ramon's
    messages which were sent/typed with utf-8 character-encoding, but not
    declared as such.

    I really do wonder what you want to accomplish by that. It's hard enough
    to saturate a GBit link with for example httpd, and same goes for most
    other usage scenarios I can imagine.

    You're really going to hit limits regarding storage (if that is local).

    Ah, thank you - I couldn't even read what you wrote without beginning
    this reply, so I figured I'd follow through and remind you to send
    your email in text only (which you can do from Yahoo email, too, BTW).

    Muchas gracias, se?or!

    but if you were using a proper email client you would not have that
    problem.

    AAMOF, I'm using gmail - the problem was tiny print that my aging eyes
    have trouble reading, not an encoding issue. Plain text is simply
    easier to read....

    Or are you suggesting that gmail is not a proper email client?

    Hello all,

    Is 10 Gb supported by CentOS 4 and 5? Anyone using it?

    Some but not all 10 Gb network cards are supported.
    Some driver support is better than other...

    You can download the latest CentOS and look at the driver
    list for out of the box support. Since CentOS is built from redhat
    packaged source you can also inspect the release note on both
    the CentOS and Red Hat web pages.

    One caution is that a current kernel may support your card
    but the kernel in the install media may not if it is a very new
    part. This is easy to solve if you understand it but a road block
    if you do not.

    Do some bandwidth arithmetic and make sure that the slot you
    plug your card into can support the bandwidth you expect.
    Same for system memory.... I do know that the bandwidth of
    my little KIM-1 6502 processor based system cannot support 10Gb.

    Do some homework.... there are some good/ better/ best 10Gb parts out there now.

    One example:
    http://service.chelsio.com/site-bin/readme.cgi?FILE=linux/t3/README-cxgb3toe
    Since RHEL is supported CentOS is 'supportable'.

    Other vendors have cards and support too but a Chelsio driver
    engineer bought me a beer last month....
    or did I buy him one..... so much beer, so much good tequila and so
    little time..... well never mind.
