--------------------编程问答-------------------- 参考：http://www.ganymed.ethz.ch/ssh2/FAQ.html
Many default SSH server installations are configured to refuse the authentication type "password". Often, they only accept "publickey" and "keyboard-interactive". You have different options:
Enable password authentication. E.g., in case of OpenSSH on Fedora, edit /etc/sshd/sshd_config and change the value of "PasswordAuthentication" to "yes", then send a HUP signal to the daemon so that it re-reads its configuration.
Switch to public-key authentication. Probably the best choice.
Try to use keyboard-interactive authentication. If you have a GUI that interacts with a user, then this is doable (check out the SwingShell.java example).
In general it is a good idea to call either Connection.getRemainingAuthMethods() or Connection.isAuthMethodAvailable() before using a certain authentication method. --------------------编程问答--------------------
ava.io.IOException：密码验证失败。
原因是：java.io.IOException：密码验证方法不被服务器支持在这个阶段。
看看你服务器支持什么模式的密码验证。 SSL？？？？没用过linux --------------------编程问答-------------------- 路 过 --------------------编程问答-------------------- 如何解决呢？各位大侠 --------------------编程问答-------------------- 如何切换到这种模式呢
Switch to public-key authentication. Probably the best choice.
--------------------编程问答-------------------- 明显是密码错误了么
你用ssh连接工具用root用户root密码能登陆进去么？ --------------------编程问答-------------------- 看看这篇文章http://zoouyong20.iteye.com/blog/1122323 --------------------编程问答-------------------- 解决方法：
vi /etc/sshd/sshd_config
PasswordAuthentication yes
重启服务：
linux：
/etc/init.d/sshd restart
freebsd：
/etc/rc.d/sshd restart
补充：Java , Web 开发
