Nslookup

A utility used to find the IP address or host name of a machine on a network. To use the nslookup command on the VPN Gateway, it must have been configured to use a DNS server.

NTP (Network Time Protocol)

A protocol used to synchronize the real-time clock in a computer. There are numerous primary and secondary servers on the Internet that are synchronized to the Coordinated Universal Time (UTC) through radio, satellite or modem.

NVG

Nortel VPN Gateway.

Passphrase

Passphrases differ from passwords only in length. Passwords are usually short, from six to ten characters. Short passwords may be adequate for logging onto computer systems that are programmed to detect a large number of incorrect guesses, but they are not safe for use with encryption systems. Passphrases are usually much longer—up to 100 characters or more. Their greater length makes passphrases more secure.

PEM (Privacy Enhanced Mail)

A standard for secure e-mail on the Internet. It supports encryption, digital signatures and digital certificates as well as both private and public key methods. Keys and certificates are often stored in the PEM format.

Ping (Packet INternet Groper)

A utility used to determine whether a particular IP address is online.

PKCS12

A standard for storing private keys and certificates.

PKI (public key infrastructure)

Short for public key infrastructure, a system of digital certificates, Certificate Authorities, and other registration authorities that verify and authenticate the validity of each party involved in an Internet transaction. PKIs are currently evolving and there is no single PKI nor even a single agreed-upon standard for setting up a PKI. However, nearly everyone agrees that reliable PKIs are necessary before electronic commerce can become widespread.

A PKI is also called a trust hierarchy.
