ssh\u调度\u运行\u致命未找到匹配的密钥交换方法（在Zend Studio远程连接上）

我使用MacBookOSX作为本地机器，笔记本lUbuntu作为本地网络上的服务器。 SSH和SFTP连接与osx终端完美配合，但我在Zend Studio 11远程连接方面遇到问题（不幸的是，我无法使用最新版本的ZS…）

我在本地网络上设置了lUbuntu服务器的远程连接配置文件，其中包含本地ip地址、用户名和密码。然后，当我尝试测试连接时，它将返回错误消息“无法连接192.168上的sshd。”

lUbuntu server auth.log显示以下消息：

Feb 15 16:09:08 ubuntu sshd[1907]: fatal: ssh_dispatch_run_fatal: Connection to 192.168.###.##: no matching key exchange method found [preauth]

顺便说一句，到其他远程网络和服务器的相同远程连接工作正常

那么，我该如何解决这个问题呢

具有DEBUG3 LogLevel的整个auth.log堆栈：

双方的清单没有共同的交集：

服务器：

Feb 15 18:11:09 ubuntu sshd[2411]: debug2: kex_parse_kexinit: curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1 [preauth]

客户：

Feb 15 18:11:09 ubuntu sshd[2411]: debug2: kex_parse_kexinit: diffie-hellman-group1-sha1,diffie-hellman-group-exchange-sha1 [preauth]

您应该尝试更新到当前的JSCH版本。0.1.50不是最新版本，在当前服务器上使用它时出现了一些问题

如果不是选项，您可以临时将kex算法添加到服务器列表中，例如在

/etc/ssh/sshd_config

中添加一行：

KexAlgorithms curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

---

然后重新启动

sshd

服务器：

服务sshd restart

从客户端或服务器发布整个错误消息。我怀疑您的IDE已经过时。我已经更新了问题描述，并在服务器端添加了完整的auth.log堆栈（请参阅描述末尾）临时解决方案（使用kex算法）不起作用。。。我已经将您的kexalgoriths行添加到sshd_config的末尾，并重新启动sshd。。测试连接在auth.log中生成新错误：错误：从192.168.100.2收到断开连接：3:java.security.invalidalgorithParameterException:Prime size必须是64的倍数，并且只能在512到1024（包括）之间[preauth]，因此请尝试使用其他受支持的kex（更新了答案中的行），但是更新jsch可能是更合理的解决方案，现在它可以与您的tmp解决方案一起使用。非常感谢。我应该在JSCH更新后删除这一kex行吗？是的，您应该尝试一下，它应该可以工作。它是默认列表，添加了客户端版本支持的kex。但它已被upsteam淘汰，因此不再推荐使用。
