Linux Lab 4.1 - Fatal error when I expand Root entry

Former Member

Hi all,

    Ran into the following problem. Any pointers to resolve this would be of great help.

     Description:

     Linux Lab 4.1

     Document: Linux_on_Zynq_Lab4_1_v02.pdf

     Steps 1 to 24 go through fine.

     At Step 25, last line:

     Expand the Rot entry and after a few seconds, the tree will populate with a file system structure as see in Figure 19

     When I expand the root entry,  I see the following fatal error:

tFailed to connect sshd on 192.168.1.10:22

ttwith OK and details buttons

tThe details button gives:
tjava.net.SocketException:Network is
unreachable:coonect

t
    I did some online research on the above message but did not seem to be relevant to what I am doing.

  
tAny idea to resolve this would be of great help !!

Thank you


Adding to the above, I see that the IPv4 address as
192.168.248.1

and

192.168.40.1 for two different Ethernet Network adapters

This should not cause a conflict ?

please comment ..

    Hi lasur2,

    I think I ran into similar a similar error when developing this lab.  IIRC, it was related to not being able to establish a connection to ZedBoard because of my improper network configuration and then later on I found that the sftp server was not running on ZedBoard.

    The easiest one of these to check would be your network configuration.  Make sure that you are able to reach the ZedBoard host from your PC by pinging the IP address 192.168.1.10.  If this does not work, check your network configuration.  If your 192.168.40.1 adapter is configured for a class C network, you may need to change the address of this adapter so that it is on the same subnet as the ZedBoard address.  Something like IP=192.168.1.100 with SM=255.255.255.0 should work.  Also, I always seem to have problems on my laptop where I need to disable my wireless adapter first in order to route the SDK connections across my wired ethernet adapter to ZedBoard.

    Try looking at those things first and see if you are able to get a network configuration that works better for you.

    Regards,
