Hi
I just recently discovered Apache SSHD and am testing it to see if we can
use this to use as a client for remote SSH servers.
As part of this, I'd like to access/use keys within the local SSH agent I
have running on my machine. I couldn't find any examples for this exact
case, but yesterday I was playing with something like this:
try (SshClient client = SshClient.setUpDefaultClient()) {
client.getProperties().put(SshAgent.SSH_AUTHSOCKET_ENV_NAME,
System.getenv().get("SSH_AUTH_SOCK"));
org.apache.sshd.client.auth.pubkey.UserAuthPublicKeyFactory
factory
= new
org.apache.sshd.client.auth.pubkey.UserAuthPublicKeyFactory();
client.setUserAuthFactories(Collections.<NamedFactory<UserAuth>>singletonList(factory));
client.setAgentFactory(new UnixAgentFactory());
client.start();
.
.
.
The problem I ran into is that the AgentClient appears to require the
Apache Portable Runtime (APR) and the tcnative-1 library (stack trace
below). Is there any way to access the local SSH agent without requiring a
binary install on the machines where I'm using the SshClient?
Thanks in advance,
Patrick
