See SSH inside SSH fails with 'stdin: is not a tty' for a more detailed explanation. 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. And add your gitlab runner user to the bottom. You need to have a terminal available to run sudo so that it can prompt you for the password. However, the message that keeps appearing if the script is run via cron: Open up the sudoers file for editing in your favorite editor. Our Oracle DBA has a script (see code below) which triggers a transport script (from another user's account) to transfer the file over to an external server using the local ch33data userid. sudo: no tty present and no askpass program specified. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. Useful sudo commands to help you with your deployments to SSH Targets.

Where "major" is the correct major number.I'm stuck. 6 Answers Sorted by: 102 A simple way is to specify -t: ssh -t remotehost 'sudo. In chroot environments, these other answers may not work correctly. 3) With great power comes great responsibility. It usually boils down to these three things: 1) Respect the privacy of others. yourExecutable This directs sudo to read the password from the standard input, stdin. We trust you have received the usual lecture from the local System Administrator. So I'd inspect /dev/console or /dev/ptmx to find the correct major number, then run: mknod /dev/tty c major 0 sudo: no tty present and no askpass program specified Alternate Answer. dev/console and /dev/ptmx have the same major number. In this case, the major number is 5 and the minor number is 0. On an Ubuntu system I have available, I see these entries in /dev: crw- 1 root root 5, 1 Apr 16 18:36 consoleĬrw-rw-rw- 1 root tty 5, 2 Sep 24 15:35 ptmxĬrw-rw-rw- 1 root tty 5, 0 Sep 24 14:25 tty Alternately, to create a device, you use the mknod command, but you need to know the correct major and minor numbers for the tty device. It fails, because sudo is trying to prompt on root password and there is no pseudo-tty allocated. Regarding how to recover /dev/tty, It's possible that rebooting the server would be sufficient the system might recreate all devices in /dev during bootup. You should be able to run sudo -S to become root. sudo: no tty present and no askpass program specified How do I fix this problem on Linux or Unix based systems This is done in Fedora, RHEL, CentOS, many other Linux distribution, and Unix-like systems for security concern as it will show the password in clear text format. Sudo has an option -S to read the password from standard input instead of /dev/tty. > sudo vim /etc/sudoers Depending on the user add at the bottom of the file: Apache can check lsof as root for cronlocalbatch.php apache ALLNOPASSWD:/. ![]() You've indicated in comments that /dev/tty is missing on your system. Sudo tries to open /dev/tty for read-write and prints that error if it fails.
