    vxlan

    I've not done this through NAT, so let's start from scratch. One host or the other needs to make a connection. NAT on the right will block incoming by default, so let's concentrate on the other direction. From the right FW (192.168.19.2), send a ping to 1.2.3.4, it should arrive at the left...

    Other RAID 1 on old Supermicro server

    I've had this happen to me before. Your "good" disk has a faulty sector and the RAID card is infinitely retrying to read it. I used sysutils/ddrescue. In my case both disks were OK but had bad sectors in different places. I was able to read all the good sectors off one disk and use the...

    Solved trouble with IPv6 aliases

    Well the manpage says that ipv6_network_interfaces is the equivalent of network_interfaces and normally manual configuration of this variable is not needed. Looking at the network_interfaces, we are told that setting it to anything other than the default is deprecated. I didn't bother reading...

    Answering the 2nd part: Down all the other interfaces, grab a cat 5 cable and plug it into a switch. Try each NIC, whichever lights up is the one you want.

    want to shutdown laptop at 5% battery level.

    My laptop is console only. I have a cron job every minute that beeps when it goes below 10%. That's enough hassle to make me push the power button or plug it into power.

    6-7 devices all rsync'd at the same time would see benefit only if they hashed decently over all the links. That's hard to predict without testing. It really depends, as mer says, on the traffic pattern.

    What is your preferred science-fiction serie or movie.

    I saw the '56 version first (I still remember my Mum and her friend having afternoon coffee while it was on in the background), but the '78 is a great remake, IMHO. I'm a huge fan of Vincent Price, so the Fly '58 certainly gets my vote, but the later one was great too.
