.SH DESCRIPTION
.B dbclient
is a SSH 2 client designed to be small enough to be used in small memory
@@ -87,22 +93,40 @@ useful for working around firewalls or routers that drop connections after
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 matt@martello/44 ).
.SH ENVIRONMENT
.TP
.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.

.B DROPBEAR_PASSWORD
A password to use for remote authentication can be specified in the environment
