mina sshd questions

["Zhuyulei (A)" <zh...@huawei.com>]

Hi,
I am using mina sshd 0.12.0, but there is little documentation...I have some questions about how to use mina sshd...

I can set up ssh server and use ssh client connecting the ssh server, but now I want to do not only this...

I want to know if mina sshd can do ssh reverse, just like this:
Now I have 2 Linux machines: controller-10-68-168-154 and controller-10-68-168-156
On controller-10-68-168-154:
controller-10-68-168-154:~ # ssh -NfR 9090:localhost:22 controller-10-68-168-156
Password:
controller-10-68-168-154:~ #

On controller-10-68-168-156, I can get 127.0.0.1:9090 listenning:
controller-10-68-168-156:~ # netstat -tnl | grep 127.0.0.1
tcp        0      0 127.0.0.1:9090          0.0.0.0:*               LISTEN
controller-10-68-168-156:~ #
then I can do this to connect controller-10-68-168-154:
controller-10-68-168-156:~ # ssh -p 9090 localhost
Password:

controller-10-68-168-154:~ #

Is Mina SSHD sshServer able to do this? How can I implement this with Mina SSHD? Anyone can show me an example? Thanks.

Yes, the Mina SSHD Server supports that.
If you launch the default sshd server from the distribution:
  bin/sshd.sh -p 8000

You can then run
  ssh -NfR 9090:localhost:8000 localhost

and then connect
  ssh -p 9090 localhost

The mina ssh client process (bin/ssh.sh) does not support all those
options, but it does support all that programmatically.

You'll find plenty of port forwarding tests you can have a look at in the
source code:
