| | | | | | | | | | [channels.c] When we added support for specified bind addresses for port forwards, we added a quirk SSH_OLD_FORWARD_ADDR. There is a bug in our handling of this for -L port forwards that causes the client to listen on both v4 and v6 addresses when connected to a server with this quirk, despite having set 0.0.0.0 as a bind_address. report and patch from Jan.Pechanec AT Sun.COM; ok dtucker@

| | | | | | | | | | | | | [channels.c channels.h servconf.c sshd_config.5] Add PermitOpen directive to sshd_config which is equivalent to the "permitopen" key option. Allows server admin to allow TCP port forwarding only two specific host/port pairs. Useful when combined with Match. If permitopen is used in both sshd_config and a key option, both must allow a given connection before it will be permitted. Note that users can still use external forwarders such as netcat, so to be those must be controlled too for the limits to be effective. Feedback & ok djm@, man page corrections & ok jmc@.
