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。本文在国产openEuler 22.03 LTS系统上完成OpenSSH 9.4的编译工作。
一、准备编译环境：
1、发布一台虚拟机，最小化安装openEuler 22.03 LTS，查看系统信息如下：
[root@localhost ~]# cat /etc/os-release
NAME="openEuler"
VERSION="22.03 LTS"
ID="openEuler"
VERSION_ID="22.03"
PRETTY_NAME="openEuler 22.03 LTS"
ANSI_COLOR="0;31"
[root@localhost ~]# rpm -qa|grep openssh
openssh-8.8p1-2.oe2203.x86_64
openssh-server-8.8p1-2.oe2203.x86_64
openssh-clients-8.8p1-2.oe2203.x86_642、 修改系统源为阿里源
[root@localhost ~]# cp /etc/yum.repos.d/openEuler.repo{,.bak}
[root@localhost ~]# sed -i "s/repo.openeuler.org/mirrors.aliyun.com\/openeuler/g" /etc/yum.repos.d/openEuler.repo
[root@localhost ~]# yum install tree -y

%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.
%description server
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.

Complete!
2、因为openssh9.*加密算法只支持256位以上，因此原来v8.8的配置文件不能直接用了，先替换配置文件，再重启服务，因是CRT远程连接，建议可多重启几次：
[root@localhost x86_64]# cp /etc/ssh/sshd_config.rpmnew /etc/ssh/sshd_config
cp：是否覆盖'/etc/ssh/sshd_config'？ y
[root@localhost ssh]# systemctl restart sshd
[root@localhost ssh]# systemctl status sshd

[root@localhost ssh]# systemctl restart sshd 
3、核对版本信息：
[root@localhost ssh]# ssh -V
OpenSSH_9.4p1, OpenSSL 1.1.1v 1 Aug 2023
[root@localhost ssh]# sshd -V
OpenSSH_9.4, OpenSSL 1.1.1v 1 Aug 2023
[root@localhost ssh]# rpm -qa |grep openssh
openssh-9.4p1-oe2203.x86_64
openssh-clients-9.4p1-oe2203.x86_64
openssh-server-9.4p1-oe2203.x86_64
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。
附1：异常倒回
[root@localhost ssh]# yum remove openssh openssh-server openssh-clients
[root@localhost ssh]# yum install openssh openssh-server openssh-clients -y
附2：连接问题
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Linux服务器也会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。
可以看到连接也是没有任何问题的。
