![]() ![]() I'm still searching for that info myself actually). 1 02-21-2010 linuxgeek Registered User 78, 0 sudo: no tty present and no askpass program specified Hi Gurus: Can you help me get out of this message I already commented out the ff line in /etc/sudoers file but still prompts me for this message. Note that this issue can also indicate a password prompt when you run a. (Apologies for my point in the right direction instead of a perfect answer. sudo: no tty present and no askpass program specified. This blog attempts to explain, but perhaps could have spent more time on the 'sudo' example: So the question is, how does one emulate the "-t" option inside the Paramiko object? There's your answer. Now the remote sudo runs fine inside SSH, no complaints about tty. ![]() Localhost$ ssh -C 'sudo su - anotheruser ssh -t /run/this/executable' How do you fix this with bare ssh command? Pass in the -t, ex: In any case, you are able to run non-sudo commands using the above, but prefixing with sudo causes "no tty present". Maybe you're not allowed to touch sudoers or any other file on host2. (Why not SSH directly to the target box? Well, maybe SSH keys are only setup between host1 and host2, or the network is routed to prohibit host2 access w/o travelling through host1. Localhost$ ssh -C 'sudo su - anotheruser ssh /run/this/executable' Asking for help, clarification, or responding to other answers. The -t option forces pseudo-tty allocation. You will have to either use an askpass helper program or configure the required sudo rules to use NOPASSWD, if that is an option.FYI - may help you in your search - note you get the SAME error in plain SSH if you encapsulate one SSH command inside another, ex: Thanks for contributing an answer to Stack Overflow Please be sure to answer the question.Provide details and share your research But avoid. In order to avoid this error, we have to run ssh command as follows: ssh -t hostname sudo command ssh -t userhostname sudo command ssh -t sudo command1 /path/to/file. If sending the script over the SSH standard input like this is a requirement (instead of just copying the script to the server), then the first option will not work. Note that since you are piping your shell script to the standard input stream of the SSH connection, sudo will be unable to securely prompt for a password. This can be done in your script, for example, with something like: export SUDOASKPASS=/usr/lib/openssh/gnome-ssh-askpass sudo -A. Tell sudo to prompt for your password using an askpass program with the -A option on sudo (not to be confused with the -A option for ssh!). This is as easy as logging in with ssh -t. Ensure you have a tty so sudo can securely prompt for your password on the server. You might not get a password request from sudo with the following error message: sudo: no tty present and no askpass program specified You can try executing. To authenticate with sudo remotely, you will have to do one of the two things it is requesting. An askpass program is a (typically graphical) helper program that simply prompts for a password securely. Unless you have sudo rules allowing you to run commands with no password, it will always need to prompt for your password, either from your shell's terminal or using an askpass program, if so configured. See SSH inside SSH fails with 'stdin: is not a tty' for a more detailed explanation. Then add the NOPASSWD to the file or application the job is calling. If that does not work, check and see if a particular job is sending out the mail. < Your Username > ALL (ALL) NOPASSWD: ALL.Then add the following at the end of the file. ![]() If you pass a command to ssh, it assumes that the command doesn't need a terminal and doesn't create one, unless you pass -t. Hello, I suggest first running the following commands: sudo visudo. It provides the ability to forward your credentials so you can ssh from server to another system using your local SSH key. You need to have a terminal available to run sudo so that it can prompt you for the password. The -A option to the ssh command applies to SSH only. SSH authentication and sudo authentication are two different sets of credentials. Sudo: No Tty Present And No Askpass ProgramĬan demonstrate this problem like this: $ ssh 'sudo /usr/bin/id -u' password: sudo: no tty present and no askpass program specified. Sudo: No Tty Present And No Askpass Program.I have added a user like this: $ adduser -system -home /no/home -no-create-home -group -disabled-password -disabled-login testuser Added a user to a group: $ adduser testuser testgroup added lines to sudoers (visudo): testuser ALL=(ALL) NOPASSWD: ALL%testgroup ALL=(ALL:ALL) NOPASSWD: ALL When I try to run the bash script with the following content: #!/bin/sh sudo -u testuser /usr/bin/php /usr/local/bin/script.php But when I run this script, I get the error in the log: sudo: no tty present and no askpass program specified Edit: requiretty is not in the sudoers file. ![]()
