SSH

Since 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]

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 (
).

<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.

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.
If certResource is not set, it will look to see if a keyPairProvider has been set, and if so, it will use that for certificate based authentication.
If neither certResource nor keyPairProvider are set, it will use the username and password options for authentication. Even though the username and password are provided in the endpoint configuration and headers set with SshConstants.USERNAME_HEADER (CamelSshUsername) and SshConstants.PASSWORD_HEADER (CamelSshPassword), the endpoint configuration is surpassed and credentials set in the headers are used.

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&amp;useFixedDelay=true&amp;delay=5000&amp;pollCommand=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.
