Revision 1.27, Tue Dec 6 22:38:27 2005 UTC (18 years, 5 months ago) by reyk
Branch: MAIN
Changes since 1.26: +3 -1 lines
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
