I recall being able to go past 8000 with send_frame_size and recv_frame_size
parameters and things worked stably up to something like 8044, but it did
eventually hard cap out.
Couple extra samples sometimes helps out :)

There were 2 SD cards that came with the E310... The one that was inserted, and
another one that was in its own bag.
I am using the one that was inserted. Is that correct?

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.

Nate, Thanks for all the info..
I just want to refresh your memory that I was able to connect via serial
port... Only root was needed and no password was needed... so that worked
fine.. because this is how I altered the IP address of the E310.
So with that stated, should I just jump t refresh
Hi Konstantin,
You can try connecting via the Serial port [1]. I would suggest to first try
undoing any changes you have made to the ssh_config. By default it will not
require any passwords.
If that is not successful, I would suggest downloading a fresh release-4 image
from [2] and writing it
OK.. I did it your way and I am connecting via ping your way now too
Bu again, when I do the ssh command, it is asking for a password.
So, I am getting the samething as I was before...
Does ssh have to be setup on the E310???
Is there a way to check/reset the password on the E310?
Thanks
Hi Konstantin,
After setting the NIC to be Bridged for the VM from 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.

Hi Konstantin,
When operating in bridged mode, did you manually set the (static) IP address
within your VM?

Now, I tried to use Windows Putty to login...
I get to a screen that tells me to place login - which when I place root... it
then takes me to the prompt
root@192.168.10.2's password:
When I place enter a few times it tells me access denied.
The E310 unit is new, so I am assuming there is no pr
Nate,
As soon I put it into bridged mode, nothing works.. What I mean is that I am
not able to communicate/ping to the E310 that way.
It may work maybe for other VM software, but again, I am using Oracle
VirtualBox.
Thanks

Yes I did.. It basically asks 3 times for the password.. After the 3rd time,
the terminal goes back to prompt $...
I am thinking right now... Do I have to install ssh on the E310?

Hello Konstantin:
A quick and easy way to get a Linux system up-and-running would be to use
the Live SDR Environment.
Download the ISO image, write it to a USB 3.0 flash drive, boot from it,
and then try SSH'ing into the E310.

Hi Konstantin,
You may want to try putting your VM into a Bridge Network mode. There may be an
issue with the NAT routing. If operating in Bridged mode, ensure your Host, VM
and E3xx all have different IP addresses.

Paolo,
Thats a fundamental H/W limitation of the current FPGA design. Long story
short, it would have been inefficient to support an MTU slightly larger than a
2^N size. It’s also a pretty conservative number in terms of a an MTU that
works for 99% of Hosts and network gear.

Dear Konstantin,
can you please rather copy and paste the text from the console than
making screenshots? makes it easier to read, and research :)
Anyway, in that debug output, there's nothing indicating that the
problem is actually the USRP, and not e.g. a connection breakup by the
virtualizer. C

Hello Konstantin:
Is this a brand-new unit? There should be no password required. Maybe
someone else changed its configuration?
After changing the /etc/ssh/sshd_config file, did you restart the SSH

Hello to all the mailing list.
I'm playing around with my X310, as far as I can understand the maximum

X300_10GE_DATA_FRAME_MAX_SIZE = 8000;).

that is really peculiar, as 400k is really not a rate I'd assume you'd

Hi Marcus,
Thanks for the response. I attach the flowgraph I am using for this test,
and for which I got the "unknown data type of samples" error.
I wasn't aware that the metadata was included in the PDUs, so that makes
more sense now.
The point of moving to C++ was that the flowgraph I *really*
