There is not much to the code:
jsch = new JSch();
if (ci.getKeypath().length() > 0) {
jsch.addIdentity(ci.getKeypath());
}
session = jsch.getSession(ci.getUser(), ci.getHost(), ci.getPort());
session.setUserInfo(ci);
session.connect();
where ci implements UserInfo, but also has additional fields for the
privatekey file etc...
Maybe this is a problem because the keu is in DSA format and not RSA format?
