In Linux, the functionality of the PPP, divided into two parts: a component of the kernel which controls low-level (HDLC, IPCP, IPXCP) protocols and daemon pppd from user space that controls several high level, such as PAP and CHAP protocols. The PPP kernel driver was written by Michael Callahan and reworked by Paul Mackerras.

The current version of PPP for Linux contains the PPP daemon pppd and a program named chat to call the remote system. The pppd was from a free PPP implementation for Sun and 386BSD machines which, in turn was written by Drew Perkins and others, and maintained by Paul Mackerras. It was ported to Linux by Al Longyear. The chat was written by Karl Fox. Read the rest of this entry »

You may have read in some sites specialized in securities of the subject, Cisco CCNP certification will appear in a few months in the version 6 with fresh content and to solve new problems to which networks professionals about now face .
Specifically, the composite examination will be divided into three blocks and available from the month of July 2010:

• Implementing Cisco IP Routing (ROUTE 642-902) which replaces the current BSCI (Building Scalable Cisco Internetworks)
• Implementing Cisco IP Switched Networks (SWITCH 642-813) which replaces the current BCMSN (Building Cisco Multilayer Switching Networks)
• Troubleshooting (TShoot 642-832), which normally replace the current reviews ISCW and ONT.
