Thanks,

$username\n? was a mistake by me

I just wanted to mention that I had to use

$exp->send( "$_send\r" );
[download]

for the script to fire properly. I had been reading the perldoc's on the Expect.pm module as well as the 2 pages in the Perl Cookbook. I will add a Net::Ping and Mail::Mailer to the program next (for error checking / availability) as well as reporting. Will post to CUFP when its done. Thanks again sschneid.
