DESCRIPTION

The telnetd command is a server that supports the DARPA standard TELNET virtual
terminal protocol.  Telnetd is started by the inetd daemon when a request for a
telnet connection has been received in the /etc/services file.

When a TELNET session is started, telnetd sends TELNET options to the client
(remote) host to indicate an ability to do remote echo of characters, to
suppress go ahead, and to receive terminal-type information.

If the client host agrees, telnetd requests its terminal type.  On receipt,
telnetd checks whether the indicated type is supported on the local system.  If
not, it again requests a terminal type.  This terminal type negotiation
continues until the remote client sends an acceptable terminal type or until
the client sends the same type twice in a row, indicating that it has no other
types available.

The telnetd server supports the following TELNET options:

  o Binary

  o Echo/no echo

  o Suppress go ahead

  o Timing mark.

The telnetd command also recognizes the following options for the remote
client:

  o Binary

  o Suppress go ahead

  o Terminal type.

FLAGS

-s     Silent flag.  The -s flag causes telnetd to suppress the banner that is
       usually provided to remote users.  This flag is used whenever banner
       information, which includes the hostname, should not be made available
       to remote users.

FILES

/etc/inetd.conf     Configures the inetd daemon.
