    Default OS X, Linux Samba Server blues

    I maintain network of heterogeneous computers. Most are PC's running
    Win2k, but I also have a Mac, Windows and Linux enterprise equipment.

    This is my setup:
    Linux File Server (Samba 2.2.x)
    30 Win2k Clients
    *1* Mac OSX 10.2.6 client

    Here is my problem, and I don't think it has been like this the entire
    time my user has been on the network, so I'm thinking it could be a
    version update issue
    ....but I digress...
    When we try to copy any file of size greater than .5mb, the transfer
    is painfully slow. Putting files on the file server is not an issue,
    since the transfer rate is similar to that of the PC's, which have no
    problem either way.

    I have checked the obvious; CAT cable, ram (approaching 1gb), running
    processes, changing the Samba server send and recieve buffer size,
    etc. to no avail. I've trolled the Google groups, Macosxhints.com,
    etc, and have found a little bit of info...I'm not the only one.

    Now, unlike most (as I am told) IT professionals, I will not leave my
    Mac user out to dry. There has GOT to be an answer to this issue, I
    just haven't found it yet.

    Any help?

    My problem appears to be OSX itself. Rebooted into OS9, downloaded and
    installed an evaluation version of Dave for OS9, and the Mac
    transferred a large file in the same amount of time the Win2k clients
    do.

    Since that part is isolated, I wonder where to go from here? Does this
    latest update break OSX's TCP/IP stack?

    What hardware is the Mac?
    & have there been any recent network change/upgrade?

    I have a RevA G3 10.2.4, and a 7600/200 9.2.2 here which had
    similar problems following upgrade of switches to autonegotiate
    100Mb/s full duplex. The Ether ports couldn't handle this.
    Lucky I found a couple of Asante 590 cards to fix it.

    G4 dual 877. Onboard NIC. This is an OSX issue, without a doubt. It
    was confirmed after the OS9 reboot and DAVE install. Whether OSX is
    misconfigured, or a bug, I don't know.

    I had a similar problem. It was a mode mismatch (full-duplex vs
    half-duplex). You may need to force your Mac's NIC into the right mode
    rather than letting it autodetect. I don't have the details, but I think
    I saw a startup script on macosxhints that would do this.

    Tried that. Our hub is half-duplex, and the Mac correctly identifies
    it. I changed the duplexing on the Mac, but that just created more
    collisions.

    Thanks.
