  • Execute sudo without Password?

    7 answers



  • How do I reset a lost administrative password?

    14 answers



I have only an account with no password. The other one is the guest.



When I runsudo and and it asks to introduce the password I click ENTER, and it says to try again. I also tried to go to the account management to change the password but there I also click ENTER in the window that appears to confirm the authentication and it tells me to try again. I have no password.



Is there something that I have to write when I don't have a password by default? What can I do to solve this problem?



Also, I already did passwd and pressed enter in password UNIX (actual): and it says that passwd: token authentication error.

  • Possibly related: Execute sudo without Password? E.g. See this answer - the solution might be to set NOPASSWD: ALL in your sudoers file.

  • I can't because I can't get passed sudo command, so I can't set nothing.

  • Maybe you could do it in single-user mode? See How do I boot into single-user mode from GRUB?

  • Yes, that was just what I did to solve the problem. I used this answer. I reset the password in order to have something to put into the sudo command. Thanks, man.

  • So just to clarify, you created a password for your user account, right?

Problem in reading from socket

Image
Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I have a spark streaming program, that reads data from a socket I have craeted using: nc -lk 9999 The program reads the data from socket and exclude the "Error" messages. When I write manually in socket, it works fine. I have created a python script that prints "Error" messages frequently. I will save the result in a file using: stdbuf -oL python my_script.py &>> my_file.txt and read the file from the socket: nc -lk 9999 | tail -f my_file.txt Every thing is ok, the socket will read data from file while the file is being updated on the background, But the problem is that my spark program doen't capture the "Error" messages.

Actually the program doesn't work if I read file from socket in...
