 ====== XRouter Tour - Telnet Interfaces ======
-Up to 3 "telnet" interfaces can be configured on XRouter. The general purpose one defaults to TCP port 23. There's a sysop-only one, usually on TCP port 513, and one for machine-to-machine interactions, the so-called "Telnet Proxy".

+Up to 3 types of "telnet" interface can be configured on XRouter.
+The general purpose one defaults to TCP port 23. There's a sysop-only one, usually on TCP port 513, and one for machine-to-machine interactions, the so-called "Telnet Proxy". These are described below:

 Here's a typical login to port 23 from a Linux terminal:

 The other way to gain sysop privileges, on a more secure uplink, would be to issue the @ command followed by the plain text password, for example:

+==== Remote Login (RLOGIN) ====
+RLOGINPORT, if enabled, is intended for sysops-only. You can connect directly as a sysop, using your "sysop" password instead of your "user" one...

+==== Telnet Proxy ====
+The telnet proxy is intended mainly for machine-to-machine operations, e.g. to allow a TCP application to control the node or make outgoing NetRom/AX25 connections. The difference between this and "normal" telnet is that, after the password challenge is completed, the session switches to pure binary mode.

+The telnet proxy has been used by a several applications, including a BBS and a node crawler.
+(The text sent after login is configurable).
+On the next page we'll look at a typical use of the telnet proxy.
