FPGA ZedBoard - SSH Connection: Permission Denied #71

Closed GioAgu17 closed 7 years ago

GioAgu17 commented 7 years ago

Hi everybody,

I prepared my Linux VM with the command 'make all' in the fpga directory, and everything seemed to be ok. The SD card was also partitioned and I put all required contents on it. After this, I tried to boot the zedboard, and what it appears is:

IP-Config: Got DHCP answer from 10.79.3.252, my address is 10.79.3.220
IP-Config: Complete:

Welcome to Buildroot
buildroot login: root

Why I can't see the normal login as it is descripted in the fpga.README? Also why it starts with BuildRoot?

Thank you in advance for your attention.

I want to establish an SSH connection. So I open a new terminal and try this:

user@vivado-pcie:~$ ssh root@10.79.3.220 root@10.79.3.220's password: Permission denied, please try again. root@10.79.3.220's password: Permission denied, please try again. root@10.79.3.220's password: Permission denied (publickey,password,keyboard-interactive).

The password is not pulp, nor pulpino. I also tried to change password from the previous terminal but nothing.

What do you mean with login?

Thank you so much

Can you login to the board over uart? I think by default the password might not even be active.

but you can login over uart and then change the password with passwd to whatever you like. it is then stored on the sdcard. when you change the password you might need to first set a correct date, otherwise the ssh service might not accept it because it is too old.

I think I logged in over uart, I mean using the uart connection in the ZedBoard.

I tried to change the date, but still the root refuses my trial.

date --set "2017-05-11 12:17:00"

Thu May 11 12:17:00 UTC 2017

date

Thu May 11 12:17:02 UTC 2017

passwd

Changing password for root New password: Bad password: too weak Retype password: Password for root changed by root

passwd

Changing password for root New password: Retype password: Password for root changed by root

then again: ssh root@10.79.3.220 root@10.79.3.220's password: Permission denied, please try again. root@10.79.3.220's password: Permission denied, please try again. root@10.79.3.220's password: Permission denied (publickey,password,keyboard-interactive).

I copied my public key into the root and now it works!

Thank you so much for the help!

user@vivado-pcie:~/.ssh$ ssh root@10.79.3.220
