That doesn't work. Now instead of printing the LINE --- 3 times , it prints LINE --- just once.

Also, I am not very clear what you meant by it trying to read line from filename.

I have a surrounding while loop to that above code and that works perfectly file

Code:
while read remotehost
do
 Above mentioned Code
done < "$remotehostlist"

This while loop works fine and provides me the value of remote host.
However the inner while loop does not print the value of $line.

That is the weird part

I changed the code to try this as well.. It still doesnt work!!

Code:
while read  remotehost
do
  ssh -t $2@$remotehost  <<REMOTE

   ls /path/to/dir | while read line
     do
        echo "LINE --- $line"
     done

REMOTE
done < "$remotehostlist"

This code still prints LINE --- 3 times. But does not print value of $line
