    Re: Ubuntu Overheating on Idle

    To what does "it" refer?
    If you meant turbostat, then I disagree.

    Re: Ubuntu Overheating on Idle

    turbostat (linux-tools-common) package will work with your processor. Myself, I haven't used "sensors" for years.

    Re: No iP using static DHCP

    No.

    If you use Ubuntu as your DHCP server, everything should be good.

    I have never done that. I reserve a pool for visiting computers and phones, so they get an IP adress, but it never ever...

    Re: dhcp server and iptables

    Seiji, I disagree. As far as I can tell, yes, they broadcast when they don't know anything, but thereafter and for renewals, they use the actual addresses. Even though I have static IP addresses, my...

    Is exactly the 14 bytes, in order, of the raw ethernet frame segment for [DST MAC, SRC MAC, ETHERTYPE], and breaks down as:

  8. Re: Multiple kernel log entries with unknown mac address

    Those type of packets are often from the router or modem, and are exploratory. The IP 224.0.0.1 is a multicast address. The source MAC address seems to be from some sort of NetGear device (...
