[openbsd-compat/port-tun.c openbsd-compat/port-tun.h] Add support
for tunnel forwarding for FreeBSD and NetBSD. NetBSD's support is
limited to IPv4 tunnels only, and most versions don't support the
tap(4) device at all.
|

again by providing a sys_tun_open() function for your platform and
setting the CUSTOM_SYS_TUN_OPEN define. More work is required to match
OpenBSD's tunnel protocol, which prepends the address family to the
packet

[serverloop.c ssh.c ssh_config.5 sshd_config.5 configure.ac]
two changes to the new ssh tunnel support. this breaks compatibility
with the initial commit but is required for a portable approach.
- make the tunnel id u_int and platform friendly, use predefined types.
- support configuration of layer 2 (ethernet) or layer 3
(point-to-point, default) modes. configuration is done using the
Tunnel (yes|point-to-point|ethernet|no) option is ssh_config(5) and
restricted by the PermitTunnel (yes|point-to-point|ethernet|no) option
in sshd_config(5).

Add support for tun(4) forwarding over OpenSSH, based on an idea and
initial channel code bits by markus@. This is a simple and easy way to
use OpenSSH for ad hoc virtual private network connections, e.g.
administrative tunnels or secure wireless access. It's based on a new
ssh channel and works similar to the existing TCP forwarding support,
except that it depends on the tun(4) network interface on both ends of
the connection for layer 2 or layer 3 tunneling. This diff also adds
support for LocalCommand in the ssh(1) client.
ok djm@, markus@, jmc@ (manpages), tested and discussed with others

[channels.c clientloop.c clientloop.h misc.c misc.h ssh.c ssh_config.5]
implement support for X11 and agent forwarding over multiplex slave
connections. Because of protocol limitations, the slave connections inherit
the master's DISPLAY and SSH_AUTH_SOCK rather than distinctly forwarding
their own.

bz#413: allow optional specification of bind address for port forwardings.
Patch originally by Dan Astorian, but worked on by several people
Adds GatewayPorts=clientspecified option on server to allow remote
forwards to bind to client-specified ports.

sshd command-line arguments and configuration file options that
specify time may be expressed using a sequence of the form:
time[qualifier], where time is a positive integer value and qualifier
is one of the following:

600 600 seconds (10 minutes)
10m 10 minutes
