Dear All ,
Some interesting thing in this situation that i have discovered in this
process which i would like to share with you all.
I can't connect via ssh both the virtual IP's when i am being in root. But i
can connect via SSH with both the virtual TS's IP's which are 10.80.4.246
and 10.80.4.247 respectively by being normal user. When it asks for password
i simply enter my machine login password and i can easily connect.
Now when i am going to do the same being normal user but not sudo , i mean
start the prepare.sh script and preparing the TS1 and TS2 , i am getting one
error as "sudo: no tty present and no askpass programme specified".
Now my question is can i get connected by being normal user or i do have to
do that by being SUDO? To get rid if this no tty error do i need to change
the sudoers file in etc?
Any reply on this issue ,
Regards,
Sougata
