Richard O'Sullivan updated CAMEL-8202:
--------------------------------------
Description:
A previous issue, CAMEL-5242, "Add support for pki based auth in camel-jsch"
defined the default location of the SSH known_hosts file to as
DEFAULT_KNOWN_HOSTS = "META-INF/.ssh/known_hosts".
But this default causes excessive logging with the misleading message:
JSCH -> Permanently added 'X' (RSA) to the list of known hosts.
It is misleading because the addition is not permament. It repeats with every
SFTP connection. It is logged as a WARN which creates unnecesary review and
filtering when analyzing the log files.
Although it is possible to configure the SFTP endpoint to specify the location
of the common known_hosts file location, this must be added to every SFTP
endpoint deployed to a Camel engine. For example, in a Spring XML/DSL the
additional option is:
{code:xml}
knownHostsFile={{user.home}}/.ssh/known_hosts
{code}
FIX: Change the default to be the ".ssh/known_hosts" file in the user's home
path. In ScpOperations.java, the declaration becomes...
{code:java}
private static final String DEFAULT_KNOWN_HOSTS;
static { DEFAULT_KNOWN_HOSTS = System.getProperty("user.home") +
"/.ssh/known_hosts"; }
{code}
