.TH dbclient 1 .SH NAME dbclient \- lightweight SSH2 client .SH SYNOPSIS .B dbclient [\-Tt] [\-p .I port\fR] [\-i .I id\fR] [\-L .I l\fR:\fIh\fR:\fIr\fR] [\-R .I l\fR:\fIh\fR:\fIr\fR] [\-l .IR user ] .I host .SH DESCRIPTION .B dbclient is a SSH 2 client designed to be small enough to be used in small memory environments, while still being functional and secure enough for general use. .SH OPTIONS .TP .B \-p \fIport Remote port. Connect to port .I port on the remote host. Default is 22. .TP .B \-i \fIidfile Identity file. Read the identity from file .I idfile (multiple allowed). .TP .B \-L \fIlistenport\fR:\fIhost\fR:\fIport\fR Local port forwarding. Forward the port .I listenport on the local host through the SSH connection to port .I port on the host .IR host . .TP .B \-R \fIlistenport\fR:\fIhost\fR:\fIport\fR Remote port forwarding. Forward the port .I listenport on the remote host through the SSH connection to port .I port on the host .IR host . .TP .B \-l \fIuser Username. Login as .I user on the remote host. .TP .B \-t Allocate a pty. .TP .B \-T Don't allocate a pty. .TP .B \-N Don't request a remote shell or run any commands. Any command arguments are ignored. .TP .B \-f Fork into the background after authentication. A command argument (or -N) is required. This is useful when using password authentication. .TP .B \-g Allow non-local hosts to connect to forwarded ports. Applies to -L and -R forwarded ports, though remote connections to -R forwarded ports may be limited by the ssh server. .TP .B \-y Always accept hostkeys if they are unknown. If a hostkey mismatch occurs the connection will abort as normal. .TP .B \-W \fIwindowsize Specify the per-channel receive window buffer size. Increasing this may improve network performance at the expense of memory use. Use -h to see the default buffer size. .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. .SH ENVIRONMENT .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. .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. .SH AUTHOR Matt Johnston ([email protected]). .br Gerrit Pape ([email protected]) wrote this manual page. .SH SEE ALSO dropbear(8), dropbearkey(8) .P http://matt.ucc.asn.au/dropbear/dropbear.html
