我们正在使用 Ganymed-SSH 库并在对另一台机器执行 SSH 时遇到此错误。

[root@XXXX test]# java -classpath .:ganymed-ssh2-build210.jar Basic

谁能解释这里可能是什么问题？我们应该从哪里开始调试？来自普通 shell 的 SSH 访问正常工作。

可能你的公钥有问题

在 solaris 10 上的 141742-01/02 补丁后 ssh 失败！

在 ssh/sshd 中启用的 aes192/aes256 支持在 S10u3 或更早版本上不起作用

一种解决方法是禁用 ssh 和 sshd 的 aes192/aes256 密码。更改两个配置文件 /etc/ssh/ssh_config 和 /etc/ssh/sshd_config 并添加以下行：

密码 aes128-ctr、aes128-cbc、arcfour、3des-cbc、blowfish-cbc

您必须重新启动 sshd 以获取更改（“svcadm restart ssh”）。
