How to launch the passwd command through remsh

[Augusto Vinhaes]

I'm testing some scripts and I'd like to launch the passwd command through remsh. The problem is that the passwd command requires keyboard input and this is not possible via remsh. I always got the message "Cannot open your control terminal". Is there a way to do it ? Maybe using input redirection ...

Thanks,
Augusto

One way is to use an 'expect' script. You can download expect from:

Did you use the -n option? If you want to use it without prompting, look at using the expect language.

Hi there,

We have about 53 servers here and for changing passwords of a particular user on all the server, we do the following:

1) Change the password of the user on a particular box (in our case, the admin server).

Once this is done, we replace the corresponding line or password field of all the /etc/passwd files on all the servers for the said user.

Notes: This inter-operatability is limited to HP-UX servers only. We have 10.20 and 11.00 here and it works here.

In case you wanted a Linux box's password to be reset, this will not work there since the PAM (password authentication module) libraries are different there.

Hope this helps,

Thanks

Look into this as a start:

If you have a non-trusted non-PAM non-NIS system, you could edit the /etc/password directly and replace the password.

Here is a small C program to generate an encrypted password suitable for /etc/passwd.
(find attached a "C" subroutine that does the actual encryption)

#include

main (argc, argv)
int argc;
char *argv [];
{
char *tt[200];
make_passwd (argv[1], tt);
puts(tt);
}
