Netbeans SSH：无法连接到服务器...算法协商失败 - 如何修复？

Question

服务器提供以下调试输出。无论如何，似乎有通用算法我从 Netbeans 收到 "algorithm negotiation failed" 错误。从以下答案我知道可能是缺少算法的原因 (JSchException: Algorithm negotiation fail).

您知道出了什么问题以及如何解决吗？

Answer 1

终于在这里找到了答案：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 com-jcraft-jsch.jar 版本 x.x 复制到此文件夹

4) 重启 Netbeans

宾果！！ SSH 再次工作并与 OpenSSH x.x 服务器

一起工作
