automating password change with expect...

[InigoMontoya]

Sorry I don't mean to dump a whole block of code here but I've been trying to get this thing to work for a while now and It just keeps failing. I've narrowed it down to one last error but I can't quite figure it out. I'm hoping someone here can help.

What this section of the script is supposed to do is during a file transfer session it should be able to change the password automatically and store it in a file when prompted by the server.

I modified it a bit from when it failed and I have not tested it since. The last time it failed with a..

can not find channel named "file5" while executing "puts -nonewline $pfile $newpass"

I changed the variable named from $pfile to $pfile2 and added a new line..

set pfile2 [open $passfile w]

Perhaps I had to open the file for writing first. But this section seemed to have worked before w/out it.

If anyone has any ideas it would be greatly appreciated.
