  • Change MAC address on NICs

    I solved IT!
    udev rules!
    I used what information i got here "Change interface mac (hw) address using udev rules" to change the hardware address on udev level.
    That happens before networkd, netplan and omv detects the interface mac address.
    The only change differnce from the servefault guide is, i used KERNEL== instread of ATTRS{Serial}== to select my networks.
    I will be making a future post somewhere inhere to walktrough what I did.

  • Change MAC address on NICs

    Hello everyone


    I recently went back to OMV by installing it on a Synology DS1010+ (Its basically an small computer with a BIOS and everything), but I noticed that there was really poor network performance.

    When I dug a little deeper into the issue, I noticed that both NICs, have the same MAC address. =O

    Now, I know some advanced Linux stuff, and I have been poking around in the terminal to locate where I can set the correct MAC addresses as printed on the back of the unit, but without luck.

    I noticed that there exists some network configuration in the /etc/openmediavault/config.xml file but that was all I could find.

    I know it is possible to set static MAC addresses in config files in Linux and all I want to achieve is, to do it the most possible right way with OMV.
    Can someone point me to where I can set the MAC addresses on my NICs?

  • USB 3.0 problem on ESXi 6.0.0

    Hello all


    I've been up all night trying to work this out but with no luck
    I just installed ESXi on my Gigabyte BRIX pro gb-bxi7-4770r and I have been using ESXi on another system so I know ESXi really well.
    Before I did the installation the OMV was directly on the BRIX's SSD and the USB 3.0 was working 100%.
    The BRIX only have USB 3.0 and do not have aney USB 2 ports. So when I do the installation on a VM in ESXi, I add the xHCI before I begin, so I make shure that the OMV sees the controller.
    When the installation is done and I add my USB 3.0 devices, I noticed a VERY slow speed compared to what I was used to so I did a "lsusb" and "lsusb -t" and found this:

    Code
    frands@Exill-OMV:/$ sudo lsusb

    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

    Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

    Bus 001 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse

    Bus 001 Device 003: ID 174c:55aa ASMedia Technology Inc.

    Bus 001 Device 004: ID 0e0f:0002 VMware, Inc. Virtual USB Hub

    Bus 001 Device 005: ID 0e0f:0002 VMware, Inc. Virtual USB Hub

    Bus 001 Device 006: ID 152d:0567 JMicron Technology Corp. / JMicron USA Technology Corp.


    Code
    frands@Exill-OMV:/$ sudo lsusb -t

    /:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M

    /:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 480M

        |__ Port 1: Dev 2, If 0, Class=HID, Driver=usbhid, 12M

        |__ Port 2: Dev 3, If 0, Class=stor., Driver=usb-storage, 480M

        |__ Port 3: Dev 4, If 0, Class=hub, Driver=hub/7p, 480M

            |__ Port 1: Dev 6, If 0, Class=stor., Driver=usb-storage, 480M

        |__ Port 4: Dev 5, If 0, Class=hub, Driver=hub/7p, 480M


    Now I am really confused, because the USB 3.0 devices gets connected as a USB 2 device wich makes no sens at all and the USB 3.0 controller is there. ?(
    I have no idea what I have done wrong. I have tried to make a "Debian 7 x64" VM, where it warned me that USB 3.0 might not be supported by the operating system when I added the xHCI controller. But when I created a "Other 3.x Linux x64" VM there was no warning about the USB 3.0 controller.
    I have no idea why it won’t connect to the USB 3.0 ports and I REALLY need the speed because of the amount of data I transfer.
    Help ;(

  • SSH key configuration not working

    When I open a new PuTTY terminal, I open a pre-configured session with my servers address and the non root user I created on the server.
    This time I opened a new terminal and used the root user to login and bang: "Authenticating with public key "imported-openssh-key" from agent".!
    So all this time, I've created the keys with the root user, but I did not use the root user to login with afterwards. I used the non root user I created in the web interface.


    So far so good. I just generated a new pair of 4096 keys with the root user and now I can't login with root.
    But I added the key to the non root user in the WebGUI and now I can log in with the user but not root.
    This is getting more and more wired. But I don't need to directly login as the root user. I need to login as my own non root and from there I can su to root if needed.


    So for what I need now, its working.
    Just at final question before I mark this as solved:
    If I added a key via the WebGUI, can I then remove the /.ssh/autherized_keys file from the server?
    Because I don't need to login as root from SSH, so theoretically removing that should not effect anything.
    I can see that the public key I added to my user in the WebGUI is still showing after I saved it. Is that normal?

  • SSH key configuration not working

    Hmm. I am using puttygen to convert the key I get from the process to a private key, that I load into pagent and then I try to login.
    Should I try and generate the key with puttygen and put it into the servers authorized_keys?
    Is it better to do this via SSH or use the WebGUI?

  • SSH key configuration not working

    Hello all


    I am trying to add private key to my server, since I need the good security on SSH. I followed this guide:
    https://sites.google.com/site/…howto/generate-an-ssh-key

    I tried different times, but no success. When I have completed the guide, my putty client says that the connection was refused (Server sent publickey).
    The Authentication log on the server says the same thing.
    This is my OMV version: http://puu.sh/e1gfp/60163932a5.png


    I checked that the key was added to the authenticated keys file and enverything there is OK.
    I checked the permissions and they are fine.
    I tried to turn on and off the SSH service from the WebGUI but with no luck.
    If its not much to ask, I need a little help here.


    I had a previous server, an Ubuntu Headless Server, where I had 4096 bit private keys on and it worked fine.
    I needed new server hardware and needed good dynamic software RAID, so I found OMV and I LOVE IT!
    The difference between Ubuntu CLI and Debian CLI is not very big and I am starting to like Debian more and more.
    I just cant get those keys to work.
    If you need more information to help, please let me know :)
