Hi Eran,
Im very busy at the moment Im sorry, there is a difference between executing from local: you have TERM set. when you execute remsh, i think it doesnt read users .profile and so no tty...

I would investigate this point if I were you:
/home/vbe> remsh octant "env"
_=/usr/bin/env
PATH=/usr/bin:/usr/ccs/bin:/usr/bin/X11:/usr/contrib/bin:/usr/local/bin:
LOGNAME=vbe

caph:/home/vbe>
octant:/home/berridge $ env

I named your script stty_test01 on octant.
This is my output:
caph:/home/vbe> remsh octant "./stty_test01"
stty: : Unknown error
please give you name
victor
stty: : Unknown error
your name is victor
caph:/home/vbe>

If I find some time this evening I will give a look at your problem if you havent found a solution...

Best regards
Victor

Hi,

stty command is to disaplay or set options for the device that is your current standard input. When you run your script remotely, via remsh, your standard input is on the local machine where you are working, whereas stty is run on the remote machine. This explains the error you observe.
I think, a simple way is to ask for the user name locally and then to pass this name to the remote machine to check if an user can run what you would like to be run or not. Exactly as the standard services like telnet , ft and so on do.

Hope this helps.

Rgds.
