Switch user terminal error
Hello All,

Here I am trying to login a Linux machine as admin user from a Solaris box..

& then switch to root user..

Code I use:

Code:
ssh admin@<IP> << END
su - root  << A
echo "Hello I am logged in as root"
exit
A
exit
END

But the error I get..
Code:
su: must be run from a terminal

Hello Rudic

I am sorry if I was not clear enough..Smilie

Problem I am facing here, Using the script I am not able to switch user to root in the remote Linux machine due to the error

Code:
su: must be run from a terminal

Can you please advice? Am I missing something in my script?

Note: I am able to switch to root after a manual login in the Linux machine..

man ssh:
Quote:
-t Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing
menu services. Multiple -t options force tty allocation, even if ssh has no local tty.
