Same code cause the different result.

[叶佑群]

Hi, all

    I have code as:

/            pobj = subprocess.Popen (["smbpasswd", user], stdin 
=subprocess.PIPE)
             password += "\n"
             pobj.stdin.write (password)
             pobj.stdin.write (password)/

     the command smbpasswd will change the samba user's password, In 
shell this will run as below:

/            [root at localhost ~]# smbpasswd mytest1
             New SMB password:
             Retype new SMB password:
             [root at localhost ~]# /

     but in python code, it always prompt to wait input the password, it 
is seems that pobj.stdin.write () doesn't work. It is anything wrong 
with my code? I have another block code that runs as expected:

/            pobj = subprocess.Popen (["passwd", user], stdin = 
subprocess.PIPE)
             password = password + "\n"
             pobj.stdin.write (password)
             pobj.stdin.write (password)/

     It is so curious and I wonder why.It is the same result when 
substitute smbpasswd with pdbedit.
