SSH

Available as of Camel 2.10
The SSH component enables access to SSH servers such that you can send an SSH command, and process the response.
Maven users will need to add the following dependency to their pom.xml for this component:
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-ssh</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

ssh:[username[:password]@]host[:port][?options]

Options

Name Default Value Description
host Hostname of SSH Server
port 22 Port of the SSH Server
username Username used for authenticating with SSH Server.
password Password used for authenticating with SSH Server. Used if keyPairProvider is null.
keyPairProvider Refers to a org.apache.sshd.common.KeyPairProvider to use for loading keys for authentication. If this option is used, then password is not used.
keyType ssh-rsa Refers to a key type to load from keyPairProvider. The key types can for example be "ssh-rsa" or "ssh-dss".
certResource null Camel 2.11: Path reference to a public key certificate. Prefix path with classpath:, file:, or http:.
certFilename null @deprecated: Use certResource instead. Refers to a filename to use within file based keyPairProvider.
timeout 30000 Milliseconds to wait beforing timing out connection to SSH Server.

Consumer Only Options

Name Default Value Description
initialDelay 1000 Milliseconds before polling the SSH server starts.
delay 500 Milliseconds before the next poll of the SSH Server.
useFixedDelay true Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details.
pollCommand null Command to send to SSH Server during each poll cycle. You may need to end your command with a newline, and that must be URL encoded %0A.

Usage as a Producer endpoint

When the SSH Component is used as a Producer (.to("ssh://...")), it will send the message body as the command to execute on the remote SSH server.
Here is an example of this within the XML DSL. Note that the command has an XML encoded newline (&10;).
<route id="camel-example-ssh-producer">
  <from uri="direct:exampleSshProducer"/>
  <setBody>
    <constant>features:list&#10;</constant>
  </setBody>
  <to uri="ssh://karaf:karaf@localhost:8101"/>
  <log message="${body}"/>
</route>

Authentication

The SSH Component can authenticate against the remote SSH server using one of two mechanisms: Public Key certificate or username/password. Configuring how the SSH Component does authentication is based on how and which options are set.
  1. First, it will look to see if the certResource option has been set, and if so, use it to locate the referenced Public Key certificate and use that for authentication.
  2. If certResource is not set, it will look to see if a keyPairProvider has been set, and if so, it will use that to for certificate based authentication.
  3. If neither certResource nor keyPairProvider are set, it will use the username and password options for authentication.
The following route fragment shows an SSH polling consumer using a certificate from the classpath.
In the XML DSL,
<route>
  <from uri="ssh://scott@localhost:8101?certResource=classpath:test_rsa&seFixedDelay=true&elay=5000&ollCommand=features:list%0A"/>
  <log message="${body}"/>
</route>
In the Java DSL,
from("ssh://scott@localhost:8101?certResource=classpath:test_rsa&useFixedDelay=true&delay=5000&pollCommand=features:list%0A")
    .log("${body}");
An example of using Public Key authentication is provided in examples/camel-example-ssh-security.

Certificate Dependencies

You will need to add some additional runtime dependencies if you use certificate based authentication. The dependency versions shown are as of Camel 2.11, you may need to use later versions depending what version of Camel you are using.
<dependency>
  <groupId>org.apache.sshd</groupId>
  <artifactId>sshd-core</artifactId>
  <version>0.8.0</version>
</dependency>
<dependency>
  <groupId>org.bouncycastle</groupId>
  <artifactId>bcpg-jdk15on</artifactId>
  <version>1.47</version>
</dependency>
<dependency>
  <groupId>org.bouncycastle</groupId>
  <artifactId>bcpkix-jdk15on</artifactId>
  <version>1.47</version>
</dependency>
