sudo && rsh question

[Wilkinson,Alex]

I have a slight problem with running sudo over an rsh connection.
If I rsh to a box and pass to it the sudo command my password gets echo'ed to stdout.

eg

# rsh host sudo ls /
Password:thepassword

It seems that this is a terminal handling problem.

If I run:

# rsh host xterm -e sudo ls /

an exterm starts up and I can type my password in without it being echo'ed to stdout.

The xterm then sits in the background.

I have tryed using subshells and couldn't suss it out.

Can anyone recommend a way so that the terminal does *not* echo my password when sudo prompts
for it.

Thanks
