Method Detail

withSSHTimeout

public PortUtils.ConnectionCheckSSH withSSHTimeout(int time,
                                                   TimeUnit units)

execute

public boolean execute()
                throws InterruptedException

Tests the SSH connection. If the parent PortUtils.ConnectionCheck.withRetries(int) was set to more than zero then more than one attempt will be made, waiting (for the period specified by the parent PortUtils.ConnectionCheck.withEveryRetryWaitFor(int, TimeUnit)) between attempts. Note that, prior to testing that the port accepts SSH connection, it will first be tested to verify that it is open to TCP connections using PortUtils.ConnectionCheck.execute(), and this will also be subjected to retries, so that the total retry time for a port that is initially unavailable and then slow to accept SSH connections can be up to double what might be expected.

Returns:

true if the connection succeeded, false if it failed despite any retries.

Throws:

InterruptedException - if interrupted while waiting between retries. Connects to sshd on host:port. Retries while attempts reached with delay First with tcp port wait, then with ssh connection wait

IllegalStateException - if the TCP port is not reachable despite retries.

InterruptedException - if interrupted while waiting between retries.
