User Interface Commands
CHAPTER 2 User Interface Commands This chapter describes the commands used to access user and privileged EXEC command modes. It provides a description of the help command and features, lists the command editing keys and functions, and details the command history feature. This chapter also includes the EXEC commands that can be used to set various terminal parameters on a temporary basis (for the duration of a session). It includes the Telnet commands you can use to make a connection from a terminal to a remote router in order to configure the router. The commands to actually configure these parameters on a more permanent basis are provided in the “Terminal Line and Modem Support Commands” chapter in the Router Products Command Reference publication. You need enter only enough characters of a command to uniquely identify the command, thereby abbreviating the command syntax you type. For user interface task information and examples, refer to the “Understanding the User Interface” chapter of the Router Products Configuration Guide. User Interface Commands 2-1 clear line clear line Use the clear line EXEC command to return a terminal line to idle state. clear line line-number Syntax Description line-number Absolute line number Default None Command Mode EXEC Usage Guidelines Use this command to log out of a specific session running on another line. If the line uses a modem, the modem will be disconnected. Example In the following example, line 3 is reset: clear line 3 2-2 Router Products Command Reference connect connect To make a Telnet connection, enter the connect EXEC command at the system prompt. -

List of NMAP Scripts Use with the Nmap –Script Option
List of NMAP Scripts Use with the nmap –script option Retrieves information from a listening acarsd daemon. Acarsd decodes ACARS (Aircraft Communication Addressing and Reporting System) data in real time. The information retrieved acarsd-info by this script includes the daemon version, API version, administrator e-mail address and listening frequency. Shows extra information about IPv6 addresses, such as address-info embedded MAC or IPv4 addresses when available. Performs password guessing against Apple Filing Protocol afp-brute (AFP). Attempts to get useful information about files from AFP afp-ls volumes. The output is intended to resemble the output of ls. Detects the Mac OS X AFP directory traversal vulnerability, afp-path-vuln CVE-2010-0533. Shows AFP server information. This information includes the server's hostname, IPv4 and IPv6 addresses, and hardware type afp-serverinfo (for example Macmini or MacBookPro). Shows AFP shares and ACLs. afp-showmount Retrieves the authentication scheme and realm of an AJP service ajp-auth (Apache JServ Protocol) that requires authentication. Performs brute force passwords auditing against the Apache JServ protocol. The Apache JServ Protocol is commonly used by ajp-brute web servers to communicate with back-end Java application server containers. Performs a HEAD or GET request against either the root directory or any optional directory of an Apache JServ Protocol ajp-headers server and returns the server response headers. Discovers which options are supported by the AJP (Apache JServ Protocol) server by sending an OPTIONS request and lists ajp-methods potentially risky methods. ajp-request Requests a URI over the Apache JServ Protocol and displays the result (or stores it in a file). -

Pragma Systems & Stay-Linked™: Remote SSH Connectivity Done Right
WHITE PAPER Pragma Systems & Stay‐Linked™: Remote SSH Connectivity Done Right This paper is designed to serve as a primer for upgrading – or choosing and implementing – a highly effective, secure SSH connectivity solution. This document provides an overview of key regulatory and market developments driving the need to make remote computing systems more secure; takes a look at the origins of SSH and the factors that have led to its becoming the enterprise security protocol of choice; outlines key components of an optimal SSH‐based security approach; and, then, examines the market’s most trusted, effective, end‐to‐end, server and client SSH security solution, offered in partnership by Pragma Systems and Stay‐Linked.

Rsync Considered Inefficient and Harmful
rsync considered inefficient and harmful [email protected] [email protected] 1 RPKI uses rsync • RPKI uses rsync as its data publicaon protocol for wider public access. • The use is very constrained: – it’s a source, not a sink – It’s got specific objects in the tree (hopefully) • The use has been somewhat controversial – Not an IETF standard – Issues around efficiency/efficacy/scaling – Proposals to use HTTP, delta protocols • Tes>ng by NIST/BBN/RIPE on its behaviour 2 rsync: the protocol 3 rsync: the protocol • Andrew Tridgell design (with Paul Mackerass) – PhD thesis 1999, protocol 1996 • Designed to be highly efficient in using the net – Block checksums, only block differences sent – FleXible (a gazillion op>ons) – Send and Receive func>on de-coupled from client & server role • Massive organic feature growth in a single implementaon • Now on v31 of the protocol. – Such changes. Many op>ons. 4 rsync: the protocol 1. Connect. This iden>fies a client and a server – The client & server can be the sender or receiver and vice versa. These are completely decoupled from ‘who calls’ 2. Client passes capabili>es list, arguments – Iden>fies who takes the Sender/Receiver role 3. If Receiver, client sends a set of filter expressions at this point. 4. Receiver sends a list of checksums of blocks in files it thinks may be changed (if has none, sends null) 5. Sender sends a delta of new bytes plus eXis>ng blocks to the client to reconstruct the file 5 rsync: the protocol • The outcome is highly efficient on the wire • The checksum blocks eXchanged for the delta algorithm are a modified CRC32, that works on a sliding window. -
