Subject SSHd and STDOUT/STDIN/STDERR
Date Sun, 24 May 2009 09:37:46 GMT
Hello.
I tried SSHd. It builds nicely, everything great in general. I use
Mina 2.0.0-M5 for it. However, when I use a regular SSH in a Mac or
Unix terminal, my STDOUT/STDIN somewhere gone. Nothing happens after
I've got shell prompt.

Nothing special on server side, just:

sshd.setShellFactory(new ProcessShellFactory(new String[]{"/bin/bash",
"-i", "-l"}));

Here is a full log from server:

And this is what I'm getting in a terminal:
-----------------------------
$ ssh -p 8022 localhost
The authenticity of host '[localhost]:8022 ([::1]:8022)' can't be established.
DSA key fingerprint is ff:68:69:97:72:20:75:45:37:ba:bb:48:0e:25:0a:bb.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '[localhost]:8022' (DSA) to the list of known hosts.
bo@localhost's password:
bash: no job control in this shell
sphinx:rush bo$
-----------------------------

So I've got my shell, but when I type, nothing happens at all. I've
looked at source code and seems like channel forwards all the
input/output correctly...

Any ideas what I am missing? Thanks.
