我们正在使用Ganymed-SSH库并在与另一台机器进行SSH时遇到此错误。

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

ERROR:java.io.IOException: There was a problem while connecting to 10.X.X.X:22

有谁可以解释这里可能出现的问题？我们应该从哪里开始调试？普通shell的SSH访问正常。

Answer 1

您的公钥可能存在问题

Answer 2

在solaris 10上的141742-01 / 02补丁之后，ssh失败了！

启用ssh / sshd中的aes192 / aes256支持在S10u3或更早版本上无效

解决方法是禁用ses和sshd使用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”）。
