    Does the router you're connecting the CN box to support gigabit transfer?
    Is your net connection anywhere near fast enough to warrant needing gigabit? If the answer to both questions is No then it's pretty pointless having them in there anyway

    What I can't understand then is howcome CN says that the two cards installed fine? As you say, maybe there are instabilities in the driver.
    How many times does Windows tell you something is installed fine only for it to be totally unstable when you actually try and use it? A bad driver is a bad driver regardless of OS.

    Just a thought, the cards came with a Linux driver diskette. Maybe I could try a manual install as apposed to automatic. Think that could help?
    I don't think CN will happily let you change or install much outside of what is installed by default but there's no harm in giving it a go if you're testing things out.

    I also heard that even though you disable DHCP in the setup, CN actually doesn't do it. You have to manually kill the dhcpd to stop it from running.
    Never heard that before or had any problems at all with DHCP. It's disabled on our Censornet box and the router and enabled on our PDC. Think you're barking up the wrong tree on that one...

    I find vendor provided drivers for Linux to be junk. I wouldn't bother trying to use it.

    Good point. My router probably doesn't, but I plan on running a fibre optic network with gigabit switches so I thought why not get the cards now while testing.

    Any suggested compatable NICs I could use. I have tried the CN webpage to get compatabilites but have not been able to find any.

    Seems like the general consensus is that the NICs are the problem. I will try 10/100 3Com or RTL and see how it goes. I am at work now so will only be able to try when I get home.

    Thanks for the help so far

    The proxy server we have runs:
    Code:
    0000:02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express (rev 01)
    0000:04:01.0 Ethernet controller: 3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 24)
    However we also have the webservers (x2 machines):
    Code:
    0000:04:04.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5780 Gigabit Ethernet (rev 03)
    0000:04:04.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5780 Gigabit Ethernet (rev 03)
    And the print server:
    Code:
    0000:00:12.0 Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 7c)
    The primary MX:
    Code:
    0000:02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express (rev 01)
    0000:04:01.0 Ethernet controller: 3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 24)
    The Zimbra mail server:
    Code:
    0000:00:04.0 Ethernet controller: Silicon Integrated Systems [SiS] SiS900 PCI Fast Ethernet (rev 90)
    0000:00:09.0 Ethernet controller: Lite-On Communications Inc LNE100TX (rev 20)
    0000:00:0a.0 Ethernet controller: Lite-On Communications Inc LNE100TX (rev 20)
    And a random spare box doing nothing:
    Code:
    0000:00:02.0 Ethernet controller: Intel Corporation 82557/8/9 [Ethernet Pro 100] (rev 05)
    All of these network cards work fine on the Ubuntu Dapper, although some are unconfigured and are inactive so are not put under excessive load.

    One way or the other, you're going to have a bottleneck for the actual internet access - if you're just sharing a standard DSL connection there's no benefit to be had from trying to go gigabit right up to the router or even the CN box, especially if the router only supports 100mbit cat5 anyway. I'd definitely ditch the newer cards and go for some older ones

    I can vouch for the old cheap and cheerful realtek 8139 chipset based NICs being happy.

    Taken from the Censornet forum re a list of compatible cards -

    Not as such - but if you look in the directory
    /lib/modules/2.6.6/kernel/drivers/net
    on your CN you should find the information you need.
    To save you digging, the chipset drivers in that dir are -

    modinfo followed by a module name will give you the specifics for each module.

    Edit:
    See this thread on the Censornet forum re the 8169 module being very unhappy/unreliable/a PITA.

    You're quite correct. Suppose there's no harm running gigabit on a local LAN, but pointless for ADSL internet access.

    I will be getting 2 Realteks's this afternoon to try tonight and I will post my findings tomorrow or possibly later on from home. Fortunaltey reinstalling CN is quick.

    Thanks for the info on the chipsets, this will make life a little easier.

    Re: Censornet newbie, please help

    I had an issue with the DHCP service on a censornet box and still do. It is disabled in the setup but the service is still running when the box is restarted. It has happened a few times. One way of tracking is to see what ip your client has. Mine kept getting the DNS setting from the CN box which was the router IP.

    I think it was chrisH that told me to run the command /etc/init.d/dhcp stop. I am now in the process of removing this service from startup.

    Re: Censornet newbie, please help

    There we go, I knew that there was something to do with DHCP. It might not be significant to my situation, but seeing as though someone earlier brought it up as a possible reason I thought that I should mention it.

    Thanks for proving that all these late nights trying to get CN up and running hasn't caused me to loose my mind.

    Cheers

    Re: Censornet newbie, please help

    Just an update

    Problem solved. After replacing the NIC's, CN is now working like a charm.
    I just have to work through the guide to see what the various config options are.

    Thanks for those who have contributed.

    Cheers
    Gareth
