目前OpenSSH版本已至9.4，其作为操作系统底层管理平台软件，需要保持更新以免遭受安全攻击，编译生成rpm包是生产环境中批量升级的最佳途径。编译软件包时与当前的运行环境有较大关系，请注意本安装包系在CentOS Stream 8原生系统纯净系统下编译完成的。实际本软件包可用于Anolis OS8.*/BClinux8U8等el8运行环境的Linux系统升级openssh。
一、准备编译环境：
1、发布一台虚拟机，最小化安装CentOS Stream 8，查看系统信息如下：
[root@localhost ~]# cat /etc/os-release
NAME="CentOS Stream"
VERSION="8"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="8"
PLATFORM_ID="platform:el8"
PRETTY_NAME="CentOS Stream 8"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:8"
HOME_URL="https://centos.org/"
BUG_REPORT_URL="https://bugzilla.redhat.com/"
REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux 8"
REDHAT_SUPPORT_PRODUCT_VERSION="CentOS Stream"2、查看系统所带openssl的版本信息：
[root@localhost ~]# ssh -V
OpenSSH_8.0p1, OpenSSL 1.1.1k FIPS 25 Mar 2021
[root@localhost ~]# openssl version
OpenSSL 1.1.1k FIPS 25 Mar 2021
[root@localhost ~]# rpm -qa|grep openssh
openssh-server-8.0p1-12.el8.x86_64
openssh-8.0p1-12.el8.x86_64
openssh-clients-8.0p1-12.el8.x86_643、查看系统源：

%description
SSH (Secure SHell) is a program for logging into and executing
commands on a remote machine. SSH is intended to replace rlogin and
rsh, and to provide secure encrypted communications between two
untrusted hosts over an insecure network. X11 connections and
arbitrary TCP/IP ports can also be forwarded over the secure channel.
OpenSSH is OpenBSD's version of the last free version of SSH, bringing
it up to date in terms of security and features, as well as removing
all patented algorithms to separate libraries.
This package includes the core files necessary for both the OpenSSH
client and server. To make this package useful, you should also
install openssh-clients, openssh-server, or both.
%description clients
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package includes
the clients necessary to make encrypted connections to SSH servers.
You'll also need to install the openssh package on OpenSSH clients.

OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
the secure shell daemon (sshd). The sshd daemon allows SSH clients to
securely connect to your SSH server. You also need to have the openssh
package installed.
%description askpass
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
an X11 passphrase dialog for OpenSSH.
%description askpass-gnome
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
an X11 passphrase dialog for OpenSSH and the GNOME GUI desktop
environment.

2、版本验证：
Last login: Mon Sep 11 05:45:02 2023 from 192.168.80.1
[root@localhost ~]# ssh -V
OpenSSH_9.4p1, OpenSSL 1.1.1k FIPS 25 Mar 2021
[root@localhost ~]# sshd -V
OpenSSH_9.4, OpenSSL 1.1.1k FIPS 25 Mar 2021
[root@localhost ~]# rpm -qa |grep openssh
openssh-9.4p1-1.el8.x86_64
openssh-server-9.4p1-1.el8.x86_64
openssh-clients-9.4p1-1.el8.x86_64
[root@localhost ~]# 
可以将/root/rpmbuild/RPMS/x86_64下的软件包进行拷贝分发或放到http服务器共享。至此，rpm包制作完成。
3、注意事项
openssh升级到9.*后加密算法最低要求256位，因此升级openssh后低版本的客户端和CRT都将无法连接，报以下错误：
Key exchange failed.
No compatible key-exchange method. The server supports these methods: sntrup761x25519-sha512@openssh.com,curve25519-sha256,curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256
此时其它未升级openssh的centos6服务器都连不上更新服务器的，不要以为升级失败了，只需将需要连接本服务器的主机的openssh-client也升级了即可。
Windows连接请升级SecureCRT到8.*.*版本，同时会话属性中仅启用256或512位算法，即可正常连接。
可以看到连接是没有任何问题的。文章来源：https://www.toymoban.com/news/detail-707333.html
