Further to the answer you were given last year.

We could be more specific if you state which version of Windows and which version of unix.
The general solution is to use Windows "rsh" which is specifically for running unix commands on a unix server from a Windows command prompt (or Windows Batch File). Check with your Network Administrator whether remote shell is allowed in your security policy.

You will find many methods described on the Internet to get Windows rsh to work. Here is the simplest.

1) Choose a user on the unix server "unixserver" to host the commands. "unixuser".
Do not use "root" because this is inherantly insecure.
2) Note the username you use to log into you PC. "dosuser".
3) Create (or add to) a .netrc file in the home directory of "unixuser" with permissions 600 owned by "unixuser" and containing:
Code:
ip_address_of_pc dosuser

On some systems where we have IP address above it has to be fully qualified host name which you can find out by issuing "who -R am i" from a telnet session from the same PC.

4) Test rsh from the Windows command prompt. For example run unix command "pwd".
Code:
rsh unixserver -l unixuser -n pwd

Interestingly the obvious command to try is "who am i" but this will not work because "rsh" does not have a terminal context.

The command to be executed from rsh could be a shell script containing thousands of commands.

NAME
kf -- securely forward tickets SYNOPSIS
kf [-p port | --port=port] [-l login | --login=login] [-c ccache | --ccache=ccache] [-F | --forwardable] [-G | --no-forwardable] [-h | --help] [--version] host ... DESCRIPTION
The kf program forwards tickets to a remote host through an authenticated and encrypted stream. Options supported are: -p port, --port=port port to connect to -l login, --login=login remote login name -c ccache, --ccache=ccache remote cred cache -F, --forwardable forward forwardable credentials -G, --no-forwardable do not forward forwardable credentials -h, --help --version kf is useful when you do not want to enter your password on a remote host but want to have your tickets one for example AFS. In order for kf to work you will need to acquire your initial ticket with forwardable flag, i.e. kinit --forwardable. telnet is able to forward tickets by itself. SEE ALSO
