| | Rlogin - Wikipedia, the free encyclopedia |
 | | In computing, rlogin is a Unix software utility that allows users to log in on another host via a network, communicating via TCP port 513. | | | rlogin is most commonly deployed on corporate or academic networks, where user account information is shared between all the unix machines on the network (often using NIS). | | | Due to these serious problems rlogin was rarely used across untrusted networks (like the public internet) and even in closed deployments it has fallen into relative disuse (with many Unix and Linux distributions no longer including it by default). |

| | rlogin - a Whatis.com definition |
| | Rlogin (remote login) is a Unix command that allows an authorized user to login to other UNIX machines (hosts) on a network and to interact as if the user were physically at the host computer. | | | A secure version of rlogin (slogin) was combined with two other UNIX utility, ssh and scp, in the Secure Shell suite, an interface and protocol created to replace the earlier utilities. | | | Once logged in to the host, the user can do anything that the host has given permission for, such as read, edit, or delete files. |

| | Chapter 26. Telnet and Rlogin: Remote Login |
| | Rlogin is from Berkeley Unix and was developed to work between Unix systems only, but it has been ported to other operating systems also. | | | We'll look at two examples: the first shows the client-server protocol at the start of an Rlogin session, and the second shows what happens when we type our interrupt key to abort a running process on the server that is generating lots of output. | | | Rlogin appeared with 4.2BSD and was intended for remote login only between Unix hosts. |

| | RLogin |
| | The most common problems with rlogin are found at the host end and the configuration of your remote login server software. | | | It is widely used between Unix hosts because it provides transport of more of the Unix terminal environment semantics than does the Telnet protocol, and because on many Unix hosts it can be configured not to require user entry of passwords when connections originate from trusted hosts. | | | RFC 1282 defines the rlogin protocol and how it works. |

Eight-bit mode is the default. |

| | Introduction to PuTTY |
| | SSH, Telnet and Rlogin are three ways of doing the same thing: logging in to a multi-user computer from another computer, over a network. | | | Windows computers have their own ways of networking between themselves, and unless you are doing something fairly unusual, you will not need to use any of these remote login protocols. | | | The commands, and responses, can be sent over a network, so you can sit at one computer and give commands to another one, or even to more than one. |

| | Security Vulnerability between FTP and Berkeley Rsh/Rlogin Protocols |
| | These files specify hosts that can be trusted to make such a connection; if the host is not mentioned, or the luser field does not match the trusted user on the client system (by default the same as the user on the server, but overridable), the connection is rejected. | | | Authentication is normally done by checking the files hosts.equiv (in /etc under unix), and then by looking for a file called.rhosts in the ruser's home directory. | | | Rlogin operates the same way, but the port number is 513 rather than 514, and "cmd" is replaced by /, eg "vt100/9600", and the data is terminal formatted data, where rsh is typically sending Unix-style input (normally LF-delimited lines of text, although this is by no means compulsory). |
