[Heads up] SSH server in java
Over the past days, I've been working on a implementing a SSH server
in java to replace to gshell remoting bits.
The project is currently hosted at google code:
http://code.google.com/p/sshd/
This project is based on Mina and the current status is that the ssh
protocol is in a working state, but there are still a lots of things
to iron.
I've been able to connect using openssh 5.0 and 5.1 and also jsch
(from which i borrowed from code btw) and launch an /bin/sh shell and
issue a few commands.
I'd be happy if any committer is interested to work on that to give
him commits rights on the project.

Yes, a vote is already going on to start the SSH subproject.

I will investigate more... I did not see the exception spat out on the
client when entering a bad command... perhaps that is because of the
above msgs?

Have you talked to the mina folks about it? Anyways, I can't stop
saying how thrilled I am about this. You rock! Needless to say next

Not sure what those lines mean. When I connect using OpenSSH and
launch a bad command in ServiceMix, I can see the usual output from

There are still lots of things to do, but i think i could release a

Btw, this project should soon move into Apache as a Mina subproject,
but I will do a release before that at google so that we can embed it.

Not sure what those lines mean. When I connect using OpenSSH and
launch a bad command in ServiceMix, I can see the usual output from
gshell on stderr with the ansi colors.

There are still lots of things to do, but i think i could release a
0.1 very soon.
Btw, this project should soon move into Apache as a Mina subproject,
but I will do a release before that at google so that we can embed it.

Re: [Heads up] SSH server in java
Posted by Jason Dillon <ja...@gmail.com>.
Any idea what this means:
<snip>
Bliss:Applications jason$ ssh localhost -p 8081
jason@localhost's password:
channel_by_id: 1: bad id: channel free
channel_input_success_failure: 1: unknown
channel_by_id: 1: bad id: channel free
channel_input_success_failure: 1: unknown
</snip>
This is from "OpenSSH_5.1p1, OpenSSL 0.9.7l 28 Sep 2006" on Mac OS X.
It does connect and seems to work well. Though seems to not handle
sending over exceptions, like when a command is not resolved. But I
might look into that some more later today.
Whats the status of the SSH work, any release on the horizon? I'm
sold on this for the GShell remoting direction, and really this is
what I wanted from the start. So I'd like to drop the other whisper/
remoting muck and just use this.
Your thoughts?

Re: [Heads up] SSH server in java
Posted by Jason Dillon <ja...@gmail.com>.

Re: [Heads up] SSH server in java
Posted by Guillaume Nodet <gn...@gmail.com>.
Yes, i've refactored things a bit in the sshd project to make room for
the client side.
It's really limited for now and only support user/password
authentication and launching a shell.
I've implemented a gshell action at [1] for the client:
[1] https://svn.apache.org/repos/asf/servicemix/smx4/kernel/trunk/gshell/gshell-core/src/main/java/org/apache/servicemix/kernel/gshell/core/sshd/SshAction.java

Re: [Heads up] SSH server in java
Posted by Guillaume Nodet <gn...@gmail.com>.
Yes, i've refactored things a bit in the sshd project to make room for
the client side.
It's really limited for now and only support user/password
authentication and launching a shell.
I've implemented a gshell action at [1] for the client:
[1] https://svn.apache.org/repos/asf/servicemix/smx4/kernel/trunk/gshell/gshell-core/src/main/java/org/apache/servicemix/kernel/gshell/core/sshd/SshAction.java

Re: [Heads up] SSH server in java
Posted by Jason Dillon <ja...@gmail.com>.
Cool, I'm going to start a gshell-ssh module under gshell-commands for
the sshd and ssh commands, which will replace the gshell-remote bits :-)
I noticed you got some client goo in there too... how is that working?

Re: [Heads up] SSH server in java
Posted by Jason Dillon <ja...@gmail.com>.
Cool, I'm going to start a gshell-ssh module under gshell-commands for

I noticed you got some client goo in there too... how is that working?

Re: [Heads up] SSH server in java
Posted by Jason Dillon <ja...@gmail.com>.

I noticed you got some client goo in there too... how is that working?

Re: [Heads up] SSH server in java
Posted by Jason Dillon <ja...@gmail.com>.
Any idea what this means:
<snip>
Bliss:Applications jason$ ssh localhost -p 8081
jason@localhost's password:
channel_by_id: 1: bad id: channel free
channel_input_success_failure: 1: unknown
channel_by_id: 1: bad id: channel free
channel_input_success_failure: 1: unknown
</snip>
This is from "OpenSSH_5.1p1, OpenSSL 0.9.7l 28 Sep 2006" on Mac OS X.
It does connect and seems to work well. Though seems to not handle
sending over exceptions, like when a command is not resolved. But I
might look into that some more later today.
Whats the status of the SSH work, any release on the horizon? I'm
sold on this for the GShell remoting direction, and really this is
what I wanted from the start. So I'd like to drop the other whisper/
remoting muck and just use this.
Your thoughts?

Re: [Heads up] SSH server in java
Posted by Jason Dillon <ja...@gmail.com>.
Fricken awesome! I'd be more than happy to make the gshell remoting
stuff go away in favor of using ssh ;-) I will take a closer look at
this in the next day or so. I'm very excited by this work!

Re: [Heads up] SSH server in java
Posted by Jason Dillon <ja...@gmail.com>.
Any idea what this means:
<snip>
Bliss:Applications jason$ ssh localhost -p 8081
jason@localhost's password:
channel_by_id: 1: bad id: channel free
channel_input_success_failure: 1: unknown
channel_by_id: 1: bad id: channel free
channel_input_success_failure: 1: unknown
</snip>
This is from "OpenSSH_5.1p1, OpenSSL 0.9.7l 28 Sep 2006" on Mac OS X.
It does connect and seems to work well. Though seems to not handle
sending over exceptions, like when a command is not resolved. But I
might look into that some more later today.
Whats the status of the SSH work, any release on the horizon? I'm
sold on this for the GShell remoting direction, and really this is
what I wanted from the start. So I'd like to drop the other whisper/
remoting muck and just use this.
Your thoughts?

Re: [Heads up] SSH server in java
Posted by Jason Dillon <ja...@gmail.com>.
Fricken awesome! I'd be more than happy to make the gshell remoting
stuff go away in favor of using ssh ;-) I will take a closer look at
this in the next day or so. I'm very excited by this work!

Re: [Heads up] SSH server in java
Posted by Guillaume Nodet <gn...@gmail.com>.
I've just done a real quick prototype to plug into smx kernel and I've
been able to log in into smx kernel using an ssh client and issue a
few commands.
Following is the class that does everything and the spring config to
start the ssh server.
The BogusPasswordAuthenticator is a dummy class which I pasted below too.
Notice the use of stream filters to convert CR / CRLF stuff. I think
this is because both sshd and the geronimo gshell do not handle well
the pty request and/or VT100 stuff. But I'm still not sure where the
conversion should happen exactly.
Also note that i've redefined the ConsoleErrorHandlerImpl, because the
default one uses the application.getIO() for displaying errors so they
are not available remotely.
Let me know what you think, but it basically makes the whole remote
bits of gshell unused.
I have not implemented the ssh command which should be easy using jsch lib.
Let me know if / how I can help you with that bits.
==================================================
package org.apache.servicemix.kernel.gshell.core.sshd;
import com.google.code.sshd.PasswordAuthenticator;
public class BogusPasswordAuthenticator implements PasswordAuthenticator {
public Object authenticate(String username, String password) {
return (username != null && username.equals(password)) ?
username : null;
}
}

Re: [Heads up] SSH server in java
Posted by Guillaume Nodet <gn...@gmail.com>.
I've just done a real quick prototype to plug into smx kernel and I've
been able to log in into smx kernel using an ssh client and issue a
few commands.
Following is the class that does everything and the spring config to
start the ssh server.
The BogusPasswordAuthenticator is a dummy class which I pasted below too.
Notice the use of stream filters to convert CR / CRLF stuff. I think
this is because both sshd and the geronimo gshell do not handle well
the pty request and/or VT100 stuff. But I'm still not sure where the
conversion should happen exactly.
Also note that i've redefined the ConsoleErrorHandlerImpl, because the
default one uses the application.getIO() for displaying errors so they
are not available remotely.
Let me know what you think, but it basically makes the whole remote
bits of gshell unused.
I have not implemented the ssh command which should be easy using jsch lib.
Let me know if / how I can help you with that bits.
