OpenSSH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 9.6的编译工作。
一、编译环境
1、准备环境
基于vmware workstation发布的x86虚拟机，最小化安装了openEuler 22.03 LTS，版本信息如下：
[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_64
[root@localhost ~]# ssh -V
OpenSSH_8.8p1, OpenSSL 1.1.1m 14 Dec 2021
[root@localhost ~]# sshd -V
unknown option -- V
OpenSSH_8.8p1, OpenSSL 1.1.1m 14 Dec 2021
usage: sshd [-46DdeiqTt] [-C connection_spec] [-c host_cert_file]
[-E log_file] [-f config_file] [-g login_grace_time]
[-h host_key_file] [-o option] [-p port] [-u len]
[root@localhost SPECS]# openssl
OpenSSL> version
OpenSSL 1.1.1m 14 Dec 2021
OpenSSL> exit2、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

%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.
