OpenSSHのChangeLog
20051213
- (djm) OpenBSD CVS Sync
(略)
- reyk@cvs.openbsd.org 2005/12/06 22:38:28
[auth-options.c auth-options.h channels.c channels.h clientloop.c]
[misc.c misc.h readconf.c readconf.h scp.c servconf.c servconf.h]
[serverloop.c sftp.c ssh.1 ssh.c ssh_config ssh_config.5 sshconnect.c]
[sshconnect.h sshd.8 sshd_config 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
