Ssh & sudo

Shell Programming and Scripting
1

when the following command is issued the command prompt is received, how do I get past this?

ssh -t usera@hosta sudo su - userb -c  id

Unless you are root on the remote server, su will ask for a password. So I don't quite get what you are seeing.

Try this:

ssh -t usera@hosta sudo 'su - userb -c id'

Thats exactly what Jim said in post #2
I understand you ar not root then... You will have to see with your admins if then can correct the sudoers files for your requirement...

If you have sudo rights with the NOPASSWD option set, then you will not be prompted. An example line from out file reads:-

SECADMIN ALL= NOPASSWD: /usr/bin/mkdir

There may be some resistance to this option though as it means there is no challenge to the command for that user/group.

I hope that this helps,
