SFTP连接失败：DH GEX组超出范围

嗨，我想连接到一个SFTP服务器，但它一直失败，这个错误： DH GEX组超出范围

这是详细的日志…环顾四周，我发现问题与密钥大小有关

OpenSSH_7.4p1 Ubuntu-10, OpenSSL 1.0.2g 1 Mar 2016 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to **** [****] port 22. debug1: Connection established. debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_7.4p1 Ubuntu-10 debug1: Remote protocol version 2.0, remote software version XFB.Gateway Windows debug1: no match: XFB.Gateway Windows debug1: Authenticating to ****:22 as 'User' debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: algorithm: diffie-hellman-group-exchange-sha1 debug1: kex: host key algorithm: ssh-rsa debug1: kex: server->client cipher: aes256-ctr MAC: hmac-sha1 compression: none debug1: kex: client->server cipher: aes256-ctr MAC: hmac-sha1 compression: none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(2048<8192<8192) sent debug1: got SSH2_MSG_KEX_DH_GEX_GROUP ssh_dispatch_run_fatal: Connection to **** port 22: DH GEX group out of range Couldn't read packet: Connection reset by peer 

这里build议的以下解决scheme不起作用：

-o KexAlgorithms = diffie-hellman-group-exchange-sha1 -o HostKeyAlgorithms = + ssh-dss

• 在安装rpm时修改PAM文件以添加configuration更改？
• 基于文件的日志监控与邮件触发器只？
• tcpdump的默认捕获大小在类似的服务器上有所不同
• 与Jenkins Docker Plugin和Jenkins Docker Slaves混淆
• 解释/ proc / diskstats中的读取，写入和总IO时间

我也尝试这个build议这里的build议

KexDHMin = 1024

但我得到这个错误

 command-line: line 0: Bad configuration option: kexdhmin 

任何想法，我可以做什么来解决它？
