.SH DESCRIPTION
|
|
|
|
|
.B dropbear
|
|
|
|
|
is a SSH 2 server designed to be small enough to be used in small memory
|
|
|
|
|
environments, while still being functional and secure enough for general use.

.B \-W \fIwindowsize

Specify the per-channel receive window buffer size. Increasing this

.TP

|
.B \-K \fItimeout_seconds
|
|
|
|
|
Ensure that traffic is transmitted at a certain interval in seconds. This is
|
|
|
|
|
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.
