  • Does the BIOS list the card when you boot the system? (Might need to change/disable the BIOS setting from "Full Screen LOGO" or similar to see POST messages e.g. to see the memory check count, disks found, peripherals enumerated etc).

    Worth mentioning since it seems possible the card is not being recognised at all by the motherboard hardware...
    Ignore the following if you are using a modern motherboard...

    How old is the motherboard? Make and Model? Type of PCIe slots...

    1. On some very old motherboards - the x16 slot will only support graphics cards
    2. Suspect your card is PCIe V2.0. Version 2.0 cards *should* work in Version 1.x slots - but there are a few exceptions
    3. Are the slots sharing bandwidth? Two of my motherboards, for example, have this restriction


    The PCIEX1_2 and PCIEX1_3 slots share bandwidth with the PCIX4_1 slot. When the PCIEX4_1 slot is populated with x4 card or greater, the PCIEX1_2 and PCIEX1_3 slots become unavailable.

  • Dave - the command you posted produces an inconsistent system - it does not install kernel components such as kernel-abi-whitelists kernel-headers kernel-tools kernel-doc etc for those that have them installed, whereas the following does... (note the asterisk)

    Installed the new kernel and associated kernel components on ClearoS 7.2 and on both 32 / 64 bit ClearOS 6.9 systems. All three came up OK and are running..

    Will report any problems - none so far...

    HeHe - this had me going for a minute or two...

    Received an email from "root@server.lan" with the message (name of server obscured by consonants changed to x)


    0 MBytes were trimmed on 2017-06-22 for disk /dev/sda installed in xaxexax.xuxex.xxxeax

    Huh! - that's my wording of a particular script - what's going on? Has my system been hacked?
    Then thought - maybe I posted that script here...
    Voila! - whoever ran that script didn't change the email address the report was to be sent to :)

    So whoever who are (probably in Mexico according to 'whois' using the original address in the email header) - change the script so you get the email and not me...

    Re: Interesting ethernet problem

    OK - just to close this out as the replacement has arrived from China (ordered 2 so now have a spare).
    Original Dual NIC was


    Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) (rev 01)
    Subsystem: Intel Corporation PRO/1000 MT Dual Port Server Adapter

    The replacement is the same functionally - but different brand, physically slightly smaller and a newer version chipset...

    Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) (rev 03)
    Subsystem: Compaq Computer Corporation NC7170 Gigabit Server Adapter

    Machine came straight up with the new NICs - so conclude for now the old dual NIC adaptor is dead (will check for sure later in a test machine...)
    It's running my web-server amongst other duties - http://www.sraellis/tk/ - let's hope it runs reliably for several more years :)

    Tony Ellis replied to a discussion, Blank Screen ... again ...

    On the few occasions this has been encountered - a text mode install solved the 'blank screen' problem. Also setup the system so tty1 goes to the familiar Linux prompt and not the standard ClearOS login screen with the red square...

    Tony Ellis replied to a discussion, Interesting ethernet problem

    Possibly PS - but think unlikely...

    https://www.sraellis.tk/frame-34-voltages.html shows the average for the two voltages monitored has remained stable - but that of course would not pick up any instantaneous peaks or dips or problems on other voltage rails...

    Haven't looked in the machine. It is still running with the 'broken' NICs inside it and wasn't powered off, just added the usb ethernet dongles. It went straight back into operation and hasn't missed a beat since.

    We will see what happens when the replacement arrives (coming from overseas - replacements for dual NIC PCI 32-bit gigabyte adaptors are not available here... being Mini-ITX have only one PCI slot).

    Interesting ethernet problem

    This is a short story of an interesting fault. But first a small simplified part of my system setup

    The problem was this appearing at random times... only lasted for about a few seconds at most for each disruption which could be up to several hours apart.

    Tried everything to fix "alice" over about two weeks - nothing helped. Then woke up one morning to find "may" had totally
    lost internet connectivity. A check showed the e1000 PCI card in "may" had "died". Another is on order and "may" is running
    using two USB ethernet dongles temporarily while waiting. The majority of internet traffic has been moved over to "alice".

    As for my problem with "alice"... Gone :-) - so "may" was the culprit and no amount of work on "alice" would have fixed it...

    BTW "alice" was my maternal grandmother and "may" her twin sister...

    not worry about the rsync getting interrupted as it might in an ssh session.

    Use the "screen" utility from ssh for such long-running programs. You can disconnect from screen and log out of ssh if you wish. Later log back into ssh if necessary and then connect to screen. Even have multiple "screens" from one ssh session. Less resource intensive than vnc with a gui. Always install this here onto ClearOS here...

    Lots of help for this on the 'web' eg https://www.rackaid.com/blog/linux-screen-tutorial-and-how-to/

  • Great work - thanks.

    Been running 6.9 since May 1 with zero problems...
