Question

服务器提供以下调试输出。似乎有一个共同的算法无论如何我从Netbeans得到“算法协商失败”错误。从以下答案我知道可能缺少算法的原因（JSchException: Algorithm negotiation fail）。

你有什么想法会出错吗？如何解决？

答案终于在这里找到：https://netbeans.org/bugzilla/show_bug.cgi?id=251641

Netbeans XXX使用JSch库XXX。可能需要更新的库。

1）下载最新版本的JSch库（http://www.jcraft.com/）

2）将当前文件重命名为备份C：\ Program Files [当前netbeans文件夹] \ ide \ modules \ com-jcraft-jsch.jar

3）将下载的版本x.x的com-jcraft-jsch.jar复制到此文件夹

4）重启Netbeans

宾果!! SSH再次运行并与OpenSSH x.x服务器配合使用
