The boot hangs at Starting dropbear sshd... for a long time.

criminus

Hello everyone,

 

As I said, the boot hangs very long time about 1-1.5 h at

 

     Starting dropbear sshd [     2.692626] random: uninitialized urandom read (23 bytes read)

     OK

 

Or when there is openssh instead of dropbear, it hangs at

    

    Starting Network: OK

 

 

Why is this? How can I solve this?

    Hi, I don't know the answer (and don't know what board you're discussing either, is it the BeagleBone Black? or some other?), but it's worth checking you're running a recent Linux image. What instructions…

    Hi,

     

    I don't know the answer (and don't know what board you're discussing either, is it the BeagleBone Black? or some other?), but it's worth checking you're running a recent Linux image.

    What instructions are you following?

    Hi,

     

    Thanks for your reply. Board is BeagleBone Black.

     

    I used Buildroot.

     

    There is what I did:

     

         $ make beaglebone_defconfig

         $ make menuconfig

     

    Then I selected openssh on Target Packages/ Networking applications, and saved.

     

    image

     

    Then I build.

     

         $ make

    I see. That was important information.

    In that case, the problem could be anything. It could be a bug in the specific code release you're trying to build. You may need to ask on the beaglebone mailer, with further information (including what you downloaded and where). Also you'll need to mention the precise version of BeagleBone Black you're using (e.g. original BBB, or BBB-Wireless, etc) in case there's any known issue with the code.

    criminus can you rebuild without SSHD to verify the rest of the system?
