want to use output of c programme in expect
hi
i am having a c code which gives the output of my password in text format

i.e when i run my c code which which gives the password asfollows====>>>>>>
$./passwdprogram ======>>>>>>abc@123(this is the output)


now i have an expect script to remotely ssh which uses the password set in programme and works fine
if given in clear text format as follows
==========================================
#!/usr/bin/expect -f

set argu [lindex $argv 0]
set argg [lindex $argv 1]
set password "abc@123" ================here i want to change


spawn ssh user@<ip adress > sh portalhits $argu $argg
expect "^password:"
send "$password\r"
interact
==========================================
I want to use this in the following way

#!/usr/bin/expect -f

set argu [lindex $argv 0]
set argg [lindex $argv 1]
set password "./passwordprogramme" (in c) ================here i want to change


spawn ssh user@<ip adress> sh portalhits $argu $argg
expect "^password:"
send "$password\r"
interact
============================
so i want to figure that is there any way by which i can set the variable password with the output of the c code(./passwordprogramme) programme

can we do this by system() command .


Thanx Smilie

LEARN ABOUT SUSE

nwauth

NWAUTH(1)							      nwauth								 NWAUTH(1)

NAME

       nwauth - Verify username/password

SYNOPSIS

       nwauth [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -D ]

DESCRIPTION

       nwauth  does  nothing  but logging into a NetWare server. If the login was successful, an error code of 0 is returned. If the login was not
       successful, an error code of 1 is returned. It was designed for use by other programs who want authenticate users via a NetWare server.

       If there is no -P or -n option specified on command line, nwauth always expects a password on stdin. If the stdin is a tty, then  the  user
       is prompted for a password. Otherwise nwauth simply reads stdin for a password.

       nwauth  looks  up the file $HOME/.nwclient to find a file server and a user name if they are not specified on command line. See nwclient(5)
       for more information. Please note that the access permissions of .nwclient MUST be 600, for security reasons.

OPTIONS

       -h
	  -h is used to print a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user name
	  If the user name your NetWare administrator gave to you differs from your unix user-id, you should use -U to tell the server about  your
	  NetWare user name.

       -D
	  nwauth  says	that  your password is correct if you have existing connection to server with name user name. This is handy for some shell
	  scripts, but it is unacceptable for authorization modules, such as PAM, PHP or Apache. It was pointed to me that this behavior  was  not
	  well	known, and there exist at least one PAM module which does not know that (this module is not part of ncpfs; you should use PAM mod-
	  ule which comes with ncpfs instead anyway).
