Hi Li,
I have posted my comments on the code you published in the pull request - in
general, it is OK - except for a few minor issue that need to be fixed.
{quote}The UnixAgentFactory use Tomcat JNI, but I don't think it is
necessary{quote}
The usage of Tomcat JNI is neither here nor there - the JNI provides some
useful performance improvements. Although you make a good point - perhaps the
choice between the {{LocalAgentFactory}} and the {{UnixAgentFactory}} should be
made based on some user-defined property whose *default* value should be _Unix_
is {{OsUtils.isUnix()}} and _Local_ otherwise. This would mean that the user
can override this default choice - e.g., if no JNI available/wanted

Goldstein Lyor commented on SSHD-700:
-
I have reviewed the code and have a few questions/issues:
* In {{ProxyAgentFactory}} you replaced {{UnixAgentFactory}} with
{{LocalAgentFactory}} - have you tested the code on _Unix_ ? Perhaps the
correct code would be to use:
{code:java}
@Override
public List getChannelForwardingFactories(FactoryManager
manager) {
return OsUtils.isUnix() ? UnixAgentFactory.DEFAULT_FORWARDING_CHANNELS :
LocalAgentFactory.DEFAULT_FORWARDING_CHANNELS;
}
{code}
* The code is using cascaded calls - e.g.
{code:java}
session.getProperties().put("agentType", requestType);
rtn.setChannelType((String) getSession().getProperties().get("agentType"));
<-- what if not set ?
{code}
please avoid such coding as it makes things difficult to read and/or debug.
* Specifically on the issue of properties, you should use
{code:java}
PropertyResolverUtils.updateProperty(session, "agentType", requestType);
PropertyResolverUtils.getString(session, "agentType");
{code}
* We do not repeat strings (e.g. {{agentType}}) - please use a literal constant
- in this case on the {{FactoryManager}} with the appropriate *documentation*
comment as to what it is used for. In this context, please note that we do not
use camel-case - I would suggest a value of {{agent-fw-auth-type}}.
* In the code below, please replace the constants (104, 204) with properly
named literal constants in {{SshAgentConstants}}. In this context, please add a
javadoc comment link to the *documentation* on which they are based.
{code:java|title=AbstractAgentProxy#getIdentities}
byte cmd = SshAgentConstants.SSH2_AGENTC_REQUEST_IDENTITIES;
byte okcmd = SshAgentConstants.SSH2_AGENT_IDENTITIES_ANSWER;
if (CHANNEL_TYPE_IETF.equals(channelType)) {
cmd = (byte) 204;
okcmd = (byte) 104;
}
{code}
Please review, fix and re-submit as a pull request

Hi [~lfn],
I have gone over the log but have not found anything suspicious. I have merged
the changes from the branch into the _master_ so you can no clone it instead of
the special code. I wish I could help more, but like I said, agent forwarding
is not my forte. What I can suggest is that you post a question on the
{{dev@mina.apache.org}} mailing list with a reference to this issue and ask for
the community's help - perhaps someone can put you on the right track. If you
do solve the issue, I would like to ask you to update this issue along with the
code that solved it - perhaps as a pull-request - so we can either fix it or
use it as part of the documentation

I really appreciate it. When I started using Apache SSHD a few months ago, due to a lack of documentation, I could only use it by learning test cases and constant attempts. Today I found the professional guidance document has been provided, and sincerely happy. Thanks for all your efforts. I made modifications to my code based on your comments, and re-run it with SSHD 1.4.0-snapshot, the problem remains. And I have some questions: 1. I would have liked to use the SSH Client singleton, but some configurations may not share for different server shells. If I configure the agentFactory for the client instance, but the user do not provide agent forward property within server connection, an exception may throw. In addition, I also worry about thread safety for the client object, the "SSH_AUTH_SOCK" property must not be mixed for different users. So I prefer to use different SshClient object for each server shell, and close it after the client session is closed. 2. If the "channel.setAgentForwarding(true)" is not invoked, the keys won't be forwarded to the next host when I use "ssh -A nextHost" (The "SSH_AUTH_SOCK" system environment variable won't be set). 3. I have tried the UnixAgentFactory with tomcat jni and APR library in Linux server, but the problem is still there. I usually coding on Windows, and the ProxyAgentFactory indeed work for the standard agent forwarding (auth-agent-...@openssh.com). The attached file "environment.png" is my environment to reproduce the problem. I use Mina SSHD to develop a SSH jump server. If it is not clear enough, please let me know.

Goldstein Lyor commented on SSHD-700:

Hi Li,
I have not yet been able to set up the test environment (like I said, it will
take some time), but I do have a few preliminary remarks after reviewing the
code you posted.
# The code creates a new client instance every time {{startShell}} is called.
This is *wrong* (please read the documentation). The idea is to create *one*
client instance during the _main_ initialization and re-use it again and again
to create sessions. The client should be stopped when the application exits
(not really 100% necessary, but highly recommended). The code you posted
creates lots of thread, pools, etc. where they are not needed.
# The code does not register a {{ForwardingFilter}} at the client or the server
- this means that *no forwarding may occur* - again, please read the
documentation that was recently posted on the [Github MINA
site|https://github.com/apache/mina-sshd].
# The authentication process is *wrong*- if will always fail the 1st time and
require the password since you do not provide a key-pair identity - again,
please read the documentation how to properly execute the authentication.
# Please don't 2nd guess the API - if you need a {{ChannelShell}} call the
appropriate API:
{code:java}
ChannelShell channel = session.createShellChannel();
{code}
# Your code checks
{code:java}
if (env.getEnv().containsKey("SSH_AUTH_SOCK")) {
channel.setAgentForwarding(true);
}
{code}
you actually already checked this in:
{code:java}
if (env.getEnv().containsKey(SshAgent.SSH_AUTHSOCKET_ENV_NAME))
{code}
# you are setting up the server to use the {{ProxyAgentFactory}} - which
actually uses {{UnixAgentFactory}} and this requires the [Apache Portable
Runtime Library|https://apr.apache.org/] - have you installed it ? configured
it ? Made sure it is available for loading in the {{LD_LIBRARY_PATH}} (see
{{AprLibrary}} class) ?
In this context, I have never seen this kind of agent proxy run on _Windows_ -
it's not impossible, just much more complicated than _Unix_. I mention this
because _XShell_ and _XAgent_ are _Windows_ application and I am not clear as
to the set-up you are trying to test (see further below).
# Finally, in order to correctly debug this issue, please describe *exactly*
the setup your are trying to use - who is the client (_XShell_?) ? Who is the
server ? Who is the agent (_XAgent ?) ? How are they set up, etc... I recommend
you attach some text or PDF document that explains this - perhaps some drawing
of the set up environment

Hi Li,
Please try to clone https://github.com/lgoldstein/mina-sshd/tree/SSHD-700
compile it and see if it solves your problem. Try debugging it if it doesn't
and maybe diagnose what is failing - I cannot re-create it.
*Note:* some special initialization may be required similar to what I already
showed - see {{ChannelAgentForwardingFactory OPENSSH/IETF}} implementations as
well as {{SshAgentServer.PROXY_CHANNEL_TYPE}} configuration value. I believe
some kind of combination of the 2 should do the trick.
Is there some way I can re-create your problem ? I cannot download and install
_XShell_ for various reasons, so I cannot test it locally. If you can suggest
some way to use _XShell_ that would be a great help - otherwise, I rely on you
to debug the code and suggest a fix (please make sure that the fix does not
break backward compatibility)

Goldstein Lyor commented on SSHD-700:
-
XShell_ seems to be referring to [Secure Shell Authentication Agent Protocol -
Draft 2|https://tools.ietf.org/html/draft-ietf-secsh-agent-02]. Your code seems
correct, but agent forwarding is not my specialty. An initial search shows that
the following might work:
1. Define a new class that extends {{ChannelAgentForwardingFactory}} and
override its {{getName()}} method to return {{auth-agent-req}}.
2. When initializing the *server* add your factory to the server's:
{code:java}
SshServer server = SshServer.setupDefaultServer();
List factories = server.getChannelFactories();
List updated = new ArrayList<>(factories.size() + 1);
updated.addAll(factories);
updated.add(new MyForwardingFactory());
server.setChannelFactories(updated);
server.start();
{code}
I believe this should work
