Nate,

I am close to returning this unit.

I feel that I am doing everything correctly…

1.  I setup the IP static address correctly in the interfaces via the serial cable – proof that I can ping to it from both Linux and Windows
   

2.  I double checked both sshd_config files in E310 and Linux VM OS – both have the permission parameter to have no password for login.
   

3.  VM is in network bridged mode too, as you suggested.
   

When I hookup the Ethernet, I am able to ping, but when I do the ssh command to login, I am still getting the permission denied.

Please tell me any last items to double check before I return the unit, or if I can get someone on the phone to assist me with this issue.

Thanks,

Konstantin

Nate,

I think I know what the issue is…

Unfortunately, I have tried so many permutations of fixes, I think I never updated the E310’s IP address..

I hooked up the serial way and wanted to double check if I updated the
E310’s IP address…

When I tried to get to the following directory, as directed by the
website page,  I received permission denied…

What is the issue?

Thanks

Nate,

I went to start to redo the SD card and the 3rd link gave no instructions.  Here is the screen shot.

Btw,  I received a second SD card with the purchase of the E310.  I plugged that in and it did not work.

Are you sure I need to redo the card?  Or is there an SSH setup on the E310 I may need to do?

Thanks

Hi Konstantin,

Yes, I suspect there may be an issue with a configuration or change to the SSH configs on your current image. Starting with a fresh release-4 image should resolve the issue.

Again… This was not explained clearly….

Are you stating I need a micro SD Card adapter/burner to do this?

I thought I just leave it hooked up to the E310 with the SD card in it and
this can be done?

Please clarify… And if I do need a burner, which one do you suggest I buy…

Hi Konstantin,

We have no way of knowing what device the SD Card will enumerate as. There
are many guides online for using utilities like fdisk and dmesg to find the
name of the device.

Using Windows or Linux you will need to remove the micro SD card and use a
USB to micro SD card adapter to mount the disk on your host computer.

I'm sorry you are having such difficulty with the E310. There is a fair
amount of Linux knowledge which is assumed by the manuals and which is
necessary to use the E310 effectively. We can continue helping as possible,
but it will be faster and hopefully somewhat less frustrating to make use
of the many Linux guides available.

Here is one from SparkFun which covers Windows and Linux.

Hi Konstantin,

In regards to the page not showing instructions, please copy and paste the
full links listed below. If you note within the screenshot you posted, you
have the URL of:

"https://kb.ettus.com/Ettus_USRP_E300_Embedded_Family_Hardware_Resource"

The full address is:

"https://kb.ettus.com/Ettus_USRP_E300_Embedded_Family_
Hardware_Resources#SD_Card_Images"

In regards to the permission denied prompt that is being given in your
terminal screenshot -- This is because the command that you are issuing
"/etc/network/interfaces" is not valid. When you issue a command that is
the path to a file such as that, the system is attempting to pass the file
and execute it via the default shell (/bin/sh). I suspect you're attempting
to edit the file, which can be done with the utility "vi", such as "vi
/etc/network/interfaces".

I would suggest starting with a fresh "release-4" image for the E310 at
this point.

You will need to download the .xz file of the release image for the speed
grade of your device (details are in the link below for which SG you need
based on the serial number), and then decompress it with a 7z (7zip) or
other similar tool. You will then need to burn the image to the SD card,
which can be done with WinDisk32Imager or the Linux utility "dd", or
"bmaptool".

The default setting for the "release-4" image will give the E310 a static
IP address of 192.168.10.2. If you then put your VM NIC Settings into a
Bridged Mode, and set a static IP Address within the VM to "192.168.1.3",
you should be able to connect to the E310 with the root account and no
password via SSH.

Dekek,

Could the issue be that the ehternet cable that is in the unit is not
a crossover cable..  Again, I am connecting the laptop ehternet NIC
card directly to the E310…  I am assuming I need a crossover cable
since I am hooking this up without going through a router that
automatically assigns the IP address via DHCP…

If am done working on this today.. Will tell you tomorrow.

Again, this is something that is not mentioned in your app papers…

I realize that I am not a Linux expert and/or a network IP expert.. I
am a comm design expert though….  My point is, if this crossover cable
was needed, it should be better documented in your getting started
documents.

Hello,

Yes, a micro SD card adapter is needed. I'm going to add to our
documentation to highlight that point. There is no way to overwrite
the entire SD remotely. This is true for nearly every embedded system.

We do not have any recommended micro SD card adapter. There are many
from good brands such as Kingston, Anker, and Transcend on Amazon. I
have yet to encounter an adapter which will not work, including the $2
Kingston one. I use a USB3 one which supports many different card formats.

     Subject: Re: [USRP-users] When ssh'ing Getting prompt for
     Password Issue

     Hi Konstantin,

     In regards to the page not showing instructions, please copy
     and paste the full links listed below. If you note within the
     screenshot you posted, you have the URL of:

     "https://kb.ettus.com/Ettus_USRP_E300_Embedded_Family_Hardware_Resource"

     The full address is:

     "https://kb.ettus.com/Ettus_USRP_E300_Embedded_Family_Hardware_Resources#SD_Card_Images"

     In regards to the permission denied prompt that is being given
     in your terminal screenshot -- This is because the command
     that you are issuing "/etc/network/interfaces" is not valid.
     When you issue a command that is the path to a file such as
     that, the system is attempting to pass the file and execute it
     via the default shell (/bin/sh). I suspect you're attempting
     to edit the file, which can be done with the utility "vi",
     such as "vi /etc/network/interfaces".

     I would suggest starting with a fresh "release-4" image for
     the E310 at this point.

     You will need to download the .xz file of the release image
     for the speed grade of your device (details are in the link
     below for which SG you need based on the serial number), and
     then decompress it with a 7z (7zip) or other similar tool. You
     will then need to burn the image to the SD card, which can be
     done with WinDisk32Imager or the Linux utility "dd", or
     "bmaptool".

     The default setting for the "release-4" image will give the
     E310 a static IP address of 192.168.10.2. If you then put your
     VM NIC Settings into a Bridged Mode, and set a static IP
     Address within the VM to "192.168.1.3", you should be able to
     connect to the E310 with the root account and no password via SSH.

     change to the SSH configs on your current image. Starting with
     a fresh release-4 image should resolve the issue.

     suggest to first try undoing any changes you have made to the
     ssh_config. By default it will not require any passwords.

     fresh release-4 image from [2] and writing it to the SD Card.
     The SD Card section [3] of the Ettus KB will detail which
     image you need based on your device serial number.

     VirtualBox, you need to start the VM, then within the System
     Settings -> Network of the VM, manually set the NIC to have a
     static IP address.
