Hi Pratik, It looks like it is failing when it tries to read the 'y/n' response from /dev/tty. Can you check that is set up correctly on the system? Running 'strace -o logfile dbclient...' might have some clues if you send me it.
You can skip the hostkey confirmation with '-y' but that means you lose security against the SSH session being altered or monitored. Useful for debugging though.
