Here at Yahoo!, we aspire to make the world’s daily habits inspiring and entertaining. More than ever, we’re focused on building products that are beautiful and meaningful for our users. Sometimes, this means we have to make tough decisions — like closing down features that we feel aren’t adding enough value for you. This helps us spend more energy on creating experiences that make Yahoo! the most fun way to spend your time.

With this in mind, we have decided to discontinue several Yahoo! product features. This will enable us to refocus our efforts on modernizing our core Yahoo! products experiences and of course, create new ones. You can find more details below, including how the closures will work.

OpenVPN is an open source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange. It is capable of traversing network address translators (NATs) and firewalls. It was written by James Yonan and is published under the GNU General Public License (GPL).
OpenVPN allows peers to authenticate each other using a pre-shared secret key, certificates, or username/password. When used in a multiclient-server configuration, it allows the server to release an authentication certificate for every client, using signature and Certificate authority. It uses the OpenSSL encryption library extensively, as well as the SSLv3/TLSv1 protocol, and contains many security and control features.

Bagi kalangan pengguna modem, mungkin sering atau masih menggunakan mobile partner software bawaan dari masing masing modem utamanya huawei.

Mobile partner biasanya di gunakan untuk melakukan koneksi ke internet dengan menggunakan modem yang terhubung dengan jaringan nirkabel (3G/EDGE). Fungsi utamanya yakni
1. SMS/MMS
2. Telepon (Jika modem support voice call)
3. Cek USSD (modem terbaru dan mobile partner terbaru pula)
4. SIM Tolkit (tidak semua modem dan mobile partner support fitur ini)

Semakin baru modem, fitur yang di tawarkan pun semakin banyak tapi saya lebih sering memakai modem untuk internetan dan SMS.
