I'm running a bash script to execute a command on a remote host. Here is the command: 

ssh ppuser@10.101.5.91 "sudo mv /tmp/$2.tar.gz $1"

$1 and $2 are command line arguments. But while executing I'm getting this error : no tty present and no askpass program specified.

Hope you will help me, any help would be greatly appreciated. Thank You.

  • It seems that you need to set up ssh key authentication http://stackoverflow.com/questions/7260/how-do-i-setup-public-key-authentication – user3132194 Apr 22 '14 at 06:47

Somewhere in your sudoers file you have following 

Defaults requiretty

Just comment this line - remove it. Or

Defaults !requiretty

For specific program name you can also attempt following:

Defaults </path to program> requiretty

change it to 

Defaults </path to program> ! requiretty

Specific to user you can add

Defaults:username !requiretty

Adding What already have been specified in comment, For the same you will have to 

user-name    ALL=(ALL)  NOPASSWD: ALL

Its for passwordless sudo

  • Have you tried after removing every entry for tty `Defaults !requiretty` basically two things are required to run cmd on remote the way you are doing 1) requiretty removed 2) and NOPASSWD sudo for user with which you are connecting remotely. – PradyJord Apr 22 '14 at 09:24
  • Hello Jord, Thanks for the help, after adding NOPASSWD after the sudo on sudores file, it worked. I'll edit ur answer thank you..so..much... :) – Madura Dissanayake Apr 22 '14 at 10:29

Looks like you are invoking sudo, and it is not working because it doesn't have a tty bound. add 

"Defaults visiblepw"

in sudoers file enables sudo even if a console doesn't allocate a tty. Use visudo on the remote machine to add this and see if this helps.

Try this command

sshpasss -p password ssh ppuser@10.101.5.91 "sudo mv /tmp/$2.tar.gz $1"

  • Hello @Rahul, I have already added public key to the remotehost(10.101.5.91) so i need to execute the command without the password. So hope u will help, thank You.... :) – Madura Dissanayake Apr 22 '14 at 06:54
  • The OP is successfully authenticating through ssh. The error is coming from sudo. You also misspelled "sshpass". – Kenster Sep 05 '15 at 21:38
