How do I use the fingerprint scanner on a HP Probook?

Question

I researched this on SO and could not find a truly complete answer. Many people, including myself, are able to send an email through C# System.Net.Mail by using port 25 or 587 and NOT using SSL. For example, see here: https://stackoverflow.com/questions/1317809/sending-email-using-a-godaddy-account

Others have a solution using System.Web.Mail which is obsolete though: How can I send emails through SSL SMTP with the .NET Framework?

However, it seems nobody has a solution yet on how to send the emails using SSL with port 465. Does anybody have a solution or at least knows why SSL is not working from C#?

Here is the code I'm using:

try
{
    MailMessage mail = new MailMessage("[email protected]", receivingEmail, subject, body);
    string host = "smtpout.secureserver.net";
    int port = 465; // it's 465 if using SSL, otherwise 25 or 587
    SmtpClient smtpServer = new SmtpClient(host, port);
    smtpServer.Credentials = new NetworkCredential("[email protected]", "yourpassword");
    smtpServer.EnableSsl = true;
    smtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
    smtpServer.Send(mail);
}
catch (Exception ex)
{
    // do something with the exception
    ...
}

Solution 1

You can take a look at the Fingerprint integration page on Launchpad, where there are all the infos about fingerprint readers, to see if yours is supported and how to use it on Ubuntu.

Solution 2

First, check the compatibility of your hardware.

Supported devices | freedesktop.org

Unsupported devices | freedesktop.org

Second, please understand that logging in via fingerprint identification, AKIK, is sometimes unreliable.

fprint is not entirely stable, and may not work all the time.

From the Ubuntu Forums

The rest of this post was transcribed from This post on the Ubuntu Forums.
I have not used it personally, but it was the most up to date tutorial for Ubuntu I could find. You may need to debug the gksu.py wrapper script

To configure your device:

Install fprint

sudo apt-get install fprint-demo libfprint-dev libfprint0 libpam-fprint aes2501-wy

Next, enroll your fingers using either the terminal or a graphical user interface.

Terminal

pam_fprint_enroll

Graphical

fprint_demo

Next, configure PAM so that the fingerprint reader can be useful.

gksu gedit /etc/pam.d/common-auth

Add this at the top of the file (do it multiple times for however many attempts you want to allow)

# Fingerprint only
auth sufficient pam_fprint.so

Or, use these options if you want to require the fingerprint and the password.

# Fingerprint + password
auth required pam_fprint.so

For programs using gksudo/gksu, copy the wrapper gksu.py below to /usr/local/bin/gksu add fingerprint support and enter the following code

sudo mv ./gksu.py /usr/local/bin/gksu
sudo chmod 755 /usr/local/bin/gksu
sudo apt-get install python-gnome2-extras python-pexpect

gksu.py

Are you getting a specific exception? If you are, please post the exception message. Otherwise, it's worth raising a support ticket with GoDaddy.

[jrummell]

Have tried modifying the System.Web.Mail answer to use System.Net.Mail?

[Damiano Fusco]

dash, I get a "Failure to send email" exception and the inner exception is "Unable to Send email" with another inner exception saying "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond"

[Damiano Fusco]

jrummell, no I did not try that as that answer did not actually work for me.
