Re: [Ssh-sftp-perl-users] login using scripted password?

Yeah, but I goofed on the output I provided <sheepish>  Both samples had 
"interactive=>'false'" set, but in one case, I manually entered the 
password when prompted.

When "interactive=>'false'" is commented out, here's what the output 
*really* looks like:

user@desktop ~/development/perl $ ./myscript.pl

desktop: Next method to try is publickey.
Permission denied at ./myscript.pl line 14
user@desktop ~/development/perl $

Notice that it gives me the error message "Permission denied at 
./myscript.pl line 14".  The only thing that changed in this example is 
that I added the "#" to the beginning of line 11.

Sorry for the confusion -- multitasking just provides new opportunities 
to embarrass yourself on-line :/
