  • 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.

  • Finger RFC #1288
    Network Working Group D. Zimmerman Request for Comments: 1288 Center for Discrete Mathematics and Obsoletes: RFCs 1196, 1194, 742 Theoretical Computer Science December 1991 The Finger User Information Protocol Status of this Memo This memo defines a protocol for the exchange of user information. This RFC specifies an IAB standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract This memo describes the Finger user information protocol. This is a simple protocol which provides an interface to a remote user information program. Based on RFC 742, a description of the original Finger protocol, this memo attempts to clarify the expected communication between the two ends of a Finger connection. It also tries not to invalidate the many existing implementations or add unnecessary restrictions to the original protocol definition. This edition corrects and clarifies RFC 1196.

This section contains more practical information to help you know best about Socket programming, it contains different lab exercises based on Unix and C language. We hope these exercises will provide you practice for socket programming. Towards the end of this section, we have given the list of Unix commands frequently required by the Unix users, further we have given a list of port numbers to indicate the TCP/IP services which will be helpful to you during socket programming. To successfully complete this section, the learner should have the following knowledge and skills prior to starting the section. S/he must have: • Studied the corresponding course material of BCS-052 and completed the assignments. • Proficiency to work with Unix and Linux and C interface. • Knowledge of networking concepts, including network operating system, client- server relationship, and local area network (LAN). Also, to successfully complete this section, the learner should adhere to the following: • Before attending the lab session, the learner must already have written steps/algorithms in his/her lab record. This activity should be treated as home- work that is to be done before attending the lab session. • The learner must have already thoroughly studied the corresponding units of the course material (BCS-052) before attempting to write steps/algorithms for the problems given in a particular lab session.
