[sork] Re: expect and passwd

[lody at great2cu.net]

The expect script runs now without problems!

The tip with -d at first did not help, there was no output in the logfile, 
except when a wrong parameter or command was given.

Then I inserted a new topline in passwd_expect:

#!/usr/bin/expect -d

And then called the script:

./passwd_expect <login_name> <old_passwd> <new_passwd>

With the output sent to the terminal I could debug the required strings to 
match against.

So success at last

You were all a big help.

Next step will be the synchronisation with samba password, but I think that is 
beyond the scope of this mailing list
