Answer 1

如果您的奴隶机器是Mac，那么转到系统偏好设置 - ＆gt; 分享并启用远程登录，然后重试。

Answer 2

我也有这个问题。我跟踪了奴隶的日志。

tail -f /var/log/*.log

我已经看到了这个消息。

Sep 20 14:51:43 clicrdv.aws-eu-west-01.batch-01.adm sshd[1035]: fatal: no matching mac found: client hmac-sha1-96,hmac-sha1,hmac-md5-96,hmac-md5 server hmac-sha2-512,hmac-sha2-256,hmac-ripemd160 [preauth]

然后，我在/ etc / ssh / sshd_config

中删除了这一行

#MACs hmac-sha2-512,hmac-sha2-256,hmac-ripemd160

然后重启ssh。那就没问题了。

Answer 3

我怀疑您需要为JVM安装Java Cryptography Extension。没有它，RSA密钥大小是有限的，并且没有建立身份验证。

有关详细信息，请参阅https://issues.jenkins-ci.org/browse/JENKINS-26495。

Answer 4

我遇到了这个问题，并通过用主机名替换IP地址解决了这个问题。

Answer 5

我的问题已解决，方法是用IP地址替换主机名。
