Sometimes on a Linux client you may experience SshConnector.getInstance taking up to a minute to return. This problem is caused by the JCE provider SecureRandom implementation because if there is not enough randomness available /dev/random will block until there is.
The delay can however be overcome by setting the following system property:
-Djava.security.egd=file:/dev/./urandom
This has the effect of using an alternative non-blocking random number generator however does come with the price of lower security.
