 a certain period of inactivity. The trade-off is that a session may be
 closed if there is a temporary lapse of network connectivity. A setting
 if 0 disables keepalives.
+.B \-J \fIproxy_command
+Use the standard input/output of the program \fIproxy_command\fR rather than using
+a normal TCP connection. A hostname should be still be provided, as this is used for
+comparing saved hostkeys.
+.B \B \fIendhost:endport
+"Netcat-alike" mode, where Dropbear will connect to the given host, then create a
+forwarded connection to \fIendhost\fR. This will then be presented as dbclient's
+standard input/output.
+
+Dropbear will also allow multiple "hops" to be specified, separated by commas. In
+this case a connection will be made to the first host, then a TCP forwarded 
+connection will be made through that to the second host, and so on. Hosts other than
+the final destination will not see anything other than the encrypted SSH stream. 
+This syntax can also be used with scp or rsync (specifying dbclient as the 
+ssh/rsh command). A port for a host can be specified with a slash (eg [email protected]/44 ).

+.B DROPBEAR_PASSWORD
+A password to use for remote authentication can be specified in the environment
+variable DROPBEAR_PASSWORD. Care should be taken that the password is not
+exposed to other users on a multi-user system, or stored in accessible files.
+.TP
 .B SSH_ASKPASS
 dbclient can use an external program to request a password from a user.
 SSH_ASKPASS should be set to the path of a program that will return a password
 on standard output. This program will only be used if either DISPLAY is set and
 standard input is not a TTY, or the environment variable SSH_ASKPASS_ALWAYS is
 set.
