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.

[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).

Platforms using PAM
-------------------
As of OpenSSH 4.3p1, sshd will no longer check /etc/nologin itself when
PAM is enabled. To maintain existing behaviour, pam_nologin should be
added to sshd's session stack which will prevent users from starting shell
sessions. Alternatively, pam_nologin can be added to either the auth or
account stacks which will prevent authentication entirely, but will still
return the output from pam_nologin to the client.

How to use OpenSSH-based virtual private networks
-------------------------------------------------
OpenSSH contains support for VPN tunneling using the tun(4) network
tunnel pseudo-device which is available on most platforms, either for
layer 2 or 3 traffic.
The following brief instructions on how to use this feature use
a network configuration specific to the OpenBSD operating system.
(1) Server: Enable support for SSH tunneling
To enable the ssh server to accept tunnel requests from the client, you
have to add the following option to the ssh server configuration file
(/etc/ssh/sshd_config):
PermitTunnel yes
Restart the server or send the hangup signal (SIGHUP) to let the server
reread it's configuration.
(2) Server: Restrict client access and assign the tunnel
The OpenSSH server simply uses the file /root/.ssh/authorized_keys to
restrict the client to connect to a specified tunnel and to
automatically start the related interface configuration command. These
settings are optional but recommended:
tunnel="1",command="sh /etc/netstart tun1" ssh-rsa ... reyk@openbsd.org
(3) Client: Configure the local network tunnel interface
Use the hostname.if(5) interface-specific configuration file to set up
the network tunnel configuration with OpenBSD. For example, use the
following configuration in /etc/hostname.tun0 to set up the layer 3
tunnel on the client:
inet 192.168.5.1 255.255.255.252 192.168.5.2
OpenBSD also supports layer 2 tunneling over the tun device by adding
the link0 flag:
inet 192.168.1.78 255.255.255.0 192.168.1.255 link0
Layer 2 tunnels can be used in combination with an Ethernet bridge(4)
interface, like the following example for /etc/bridgename.bridge0:
add tun0
add sis0
up
(4) Client: Configure the OpenSSH client
To establish tunnel forwarding for connections to a specified
remote host by default, use the following ssh client configuration for
the privileged user (in /root/.ssh/config):
Host sshgateway
Tunnel yes
TunnelDevice 0:any
PermitLocalCommand yes
LocalCommand sh /etc/netstart tun0
A more complicated configuration is possible to establish a tunnel to
a remote host which is not directly accessible by the client.
The following example describes a client configuration to connect to
the remote host over two ssh hops in between. It uses the OpenSSH
ProxyCommand in combination with the nc(1) program to forward the final
ssh tunnel destination over multiple ssh sessions.
Host access.somewhere.net
User puffy
Host dmzgw
User puffy
ProxyCommand ssh access.somewhere.net nc dmzgw 22
Host sshgateway
Tunnel Ethernet
TunnelDevice 0:any
PermitLocalCommand yes
LocalCommand sh /etc/netstart tun0
ProxyCommand ssh dmzgw nc sshgateway 22
The following network plan illustrates the previous configuration in
combination with layer 2 tunneling and Ethernet bridging.

192.168.1.25
(5) Client: Connect to the server and establish the tunnel
Finally connect to the OpenSSH server to establish the tunnel by using
the following command:
ssh sshgateway
It is also possible to tell the client to fork into the background after
the connection has been successfully established:
ssh -f sshgateway true
Without the ssh configuration done in step (4), it is also possible
to use the following command lines:
ssh -fw 0:1 sshgateway true
ifconfig tun0 192.168.5.1 192.168.5.2 netmask 255.255.255.252
Using OpenSSH tunnel forwarding is a simple way to establish secure
and ad hoc virtual private networks. Possible fields of application
could be wireless networks or administrative VPN tunnels.
Nevertheless, ssh tunneling requires some packet header overhead and
runs on top of TCP. It is still suggested to use the IP Security
Protocol (IPSec) for robust and permanent VPN connections and to
interconnect corporate networks.

* added test for HAVE_LONG_DOUBLE
*
* Ben Lindstrom <mouring@eviladmin.org> 02/12/01 for OpenSSH
* Removed all hint of VARARGS stuff and banished it to the void,
* and did a bit of KNF style work to make things a bit more
* acceptable. Consider stealing from mutt or enlightenment.
* tridge@samba.org, idra@samba.org, April 2001
* got rid of fcvt code (twas buggy and made testing harder)
* added C99 semantics
*
* date: 2002/12/19 19:56:31; author: herb; state: Exp; lines: +2 -0
* actually print args for %g and %e
*
* date: 2002/06/03 13:37:52; author: jmcd; state: Exp; lines: +8 -0
* Since includes.h isn't included here, VA_COPY has to be defined here. I don't
* see any include file that is guaranteed to be here, so I'm defining it
* locally. Fixes AIX and Solaris builds.
*
* date: 2002/06/03 03:07:24; author: tridge; state: Exp; lines: +5 -13
* put the ifdef for HAVE_VA_COPY in one place rather than in lots of
* functions
*
* date: 2002/05/17 14:51:22; author: jmcd; state: Exp; lines: +21 -4
* Fix usage of va_list passed as an arg. Use __va_copy before using it
* when it exists.
*
* date: 2002/04/16 22:38:04; author: idra; state: Exp; lines: +20 -14
* Fix incorrect zpadlen handling in fmtfp.
* Thanks to Ollie Oldham <ollie.oldham@metro-optix.com> for spotting it.
* few mods to make it easier to compile the tests.
* addedd the "Ollie" test to the floating point ones.
*
* Martin Pool (mbp@samba.org) April 2003
* Remove NO_CONFIG_H so that the test case can be built within a source
* tree with less trouble.
* Remove unnecessary SAFE_FREE() definition.
*
* Martin Pool (mbp@samba.org) May 2003
* Put in a prototype for dummy_snprintf() to quiet compiler warnings.
*
* Move #endif to make sure VA_COPY, LDOUBLE, etc are defined even
* if the C library has some snprintf functions already.

- Similarly, if you do not have "scp" in your system's $PATH then the
multiplex scp tests will fail (since the system's shell startup scripts
will determine where the shell started by sshd will look for scp).
- Recent GNU coreutils deprecate "head -[n]": this will cause the yes-head
test to fail. The old behaviour can be restored by setting (and
exporting) _POSIX2_VERSION=199209 before running the tests.
