JSch session.connect 错误:算法协商失败

问题描述 投票:0回答:1

尝试通过 Jsch 连接到 SFTP 服务器,我正在使用 com.github.mwiede:jsch:0.1.72 出现以下错误:

session.connect()

我检查了另一个SO(JSchException:算法协商失败),但潜在的错误是不同的。 Jsch日志如下:

我能够通过以下设置解决此问题:

session.setConfig("kex", session.getConfig("kex") + ",diffie-hellman-group1-sha1")
session.setConfig("server_host_key", session.getConfig("server_host_key") + ",ssh-dss")
